Feasibility and Preliminary Efficacy of a New Online Self-Help Intervention for Depression among Korean College Students' Families. Applying innovative online approaches to interventions for preventing depression is necessary. Since depressive emotions are typically shared within the family, the development of interventions involving family members is critical. This study thus aimed to examine the feasibility, acceptability, and preliminary outcomes of a new online self-help intervention, MindGuide, among Korean college students' families. We developed MindGuide, which integrates cognitive behavioral therapy with mindfulness and an emotional regulation approach. A one-group pretest-posttest design was used to measure the changes in the Center for Epidemiological Studies Depression Scale, the Attitude Toward Suicide scale, and the Satisfaction With Life Scale before and after the intervention. Of the 34 families that began the program, completion rates were 88.2%, 85.3%, and 91.2% for fathers, mothers, and children, respectively. The findings indicated that the MindGuide program is feasible and acceptable for families of Korean college students. The results support the potential effect of MindGuide on reducing depression, improving positive attitudes toward suicide prevention, and enhancing family relationships in participants at risk of depression. However, future research is needed to thoroughly explore and evaluate the efficacy of the MindGuide program.

Evaluating the Efficacy of Internet-Delivered Cognitive Behavioral Therapy Blended With Synchronous Chat Sessions to Treat Adolescent Depression: Randomized Controlled Trial. Depression is a common and serious problem among adolescents, but few seek or have access to therapy. Internet-delivered cognitive behavioral therapies (ICBTs), developed to increase treatment access, show promise in reducing depression. The inclusion of coach support in treatment is desired and may be needed. The aim of this study was to determine the efficacy of an ICBT protocol blended with weekly real-time therapist sessions via chat; blended treatment, for adolescent depression, including major depressive episode (MDE). The protocol has previously been evaluated in a controlled study. In a two-arm randomized controlled trial, adolescents 15 to 19 years of age were recruited through a community setting at the national level in Sweden (n=70) and allocated to either 8 weeks of treatment or to minimal attention control. Depression was assessed at baseline, at posttreatment, and at 12 months following treatment (in the intervention group). The primary outcome was self-reported depression level as measured with the Beck Depression Inventory II at posttreatment. The intervention was offered without the need for parental consent. Over two weeks, 162 adolescents registered and completed the baseline screening. Eligible participants (n=70) were on average 17.5 years of age (SD 1.15), female (96%, 67/70), suffered from MDE (76%, 53/70), had no previous treatment experience (64%, 45/70), and reported guardian(s) to be aware about their depression state (71%, 50/70). The average intervention completion was 74% (11.8 of 16 modules and sessions). Following the treatment, ICBT participants demonstrated a significant decrease in depression symptoms compared with controls (P<.001), corresponding to a large between-group effect (intention-to-treat analysis: d=0.86, 95% CI 0.37-1.35; of completer analysis: d=0.99, 95% CI 0.48-1.51). A significant between-group effect was observed in the secondary depression outcome (P=.003); clinically significant improvement was found in 46% (16/35) of ICBT participants compared with 11% (4/35) in the control group (P=.001). The results are in line with our previous study, further demonstrating that adolescents with depression can successfully be engaged in and experience significant improvement following ICBT blended with therapist chat sessions. Findings on participants' age and baseline depression severity are of interest in relation to used study methods. ClinicalTrials.gov NCT02363205; https://clinicaltrials.gov/ct2/show/NCT02363205.

Self-compassion enhances the efficacy of explicit cognitive reappraisal as an emotion regulation strategy in individuals with major depressive disorder. Cognitive reappraisal has been shown to be an effective strategy to regulate depressed mood in healthy and remitted depressed individuals. However, individuals currently suffering from a clinical depression often experience difficulties in utilizing this strategy. Therefore, the goal of this study was to examine whether the efficacy of explicit cognitive reappraisal in major depressive disorder can be enhanced through the use of self-compassion and emotion-focused acceptance as preparatory strategies. Thereby, explicit cognitive reappraisal refers to purposefully identifying, challenging, and modifying depressiogenic cognitions to reduce depressed mood. To test our hypotheses, we induced depressed mood at four points in time in 54 participants (64.8% female; age M = 35.59, SD = 11.49 years) meeting criteria for major depressive disorder. After each mood induction, participants were instructed to either wait, or employ self-compassion, acceptance, or reappraisal to regulate their depressed mood. Depressed mood was assessed before and after each mood induction and regulation period on a visual analog scale. Results indicated that participants who had utilized self-compassion as a preparatory strategy experienced a significantly greater reduction of depressed mood during reappraisal than did those who had been instructed to wait prior to reappraisal. Participants who had used acceptance as a preparatory strategy did not experience a significantly greater reduction of depressed mood during subsequent reappraisal than those in the waiting condition. These findings provide preliminary evidence that the efficacy of explicit cognitive reappraisal is moderated by the precursory use of other emotion regulation strategies. In particular, they suggest that depressed individuals might benefit from using self-compassion to facilitate the subsequent use of explicit cognitive reappraisal.

[Behavioral Activation for Depression: Theory and Practice]. Behavioral activation (BA) has recently attracted marked attention. While cognitive therapy focuses on the cognitive distortion of patients with depression and asks them to change their behaviors as the process of altering the cognitive distortion, BA pays attention to behavior to avoid an unpleasant situation or social situation as a key symptom that leads to persistence of the depression. Avoidance behaviors are often seen during every process of depression, from onset to recurrence. Avoidance behaviors, a decrease in pleasant phenomena, or increase in unpleasant phenomena, result in reinforcing a depressive mood. If patients can set appropriate behavioral targets and achieve them, the beneficial behaviors will be further promoted with positive feed-back. The behavioral change, as-a consequence, will result in improvement of the mood, cognition, and depression itself. In this manuscript, the author presents two clinical cases, in which BA assisted the patients in recovering from their depression. The first case was a male in his thirties who repeatedly took sick leave from his work because of maladjustment, which resulted in persistent depression. The second case was a female in her thirties who suffered from OCD and then became maladjusted to her place of work, depressive, and emotionally unstable. In both cases, avoidant behaviors caused their conditions to persist. Appropriate activities formed by BA improved their moods, and their self-efficacies were gradually regained. It was suggested that BA is markedly effective, especially in patients whose avoidant behaviors mainly cause the persistence of their depressive symptoms.

Randomized cost-effectiveness trial of group interpersonal psychotherapy (IPT) for prisoners with major depression. This study tested the effectiveness and cost-effectiveness of interpersonal psychotherapy (IPT) for major depressive disorder (MDD) among prisoners. It is the first fully powered randomized trial of any treatment (pharmacological or psychosocial) targeting MDD among incarcerated individuals. One hundred eighty-one male (n = 117) and female (n = 64) prisoners from prison facilities in 2 states were randomized to group IPT (delivered by master's-level and nonspecialist prison counselors) for MDD plus prison treatment as usual (TAU) or to TAU alone. Participants' average age was 39 (range = 20-61); 20% were African American and 19% were Hispanic. Outcomes assessed at posttreatment and 3-month follow-up included depressive symptoms (primary; assessed using the Hamilton Rating Scale for Depression), suicidality (assessed with the Beck Scale for Suicide Ideation and Beck Hopelessness Scale), in-prison functioning (i.e., enrollment in correctional programs; discipline reports; aggression/victimization; and social support), remission from MDD, and posttraumatic stress disorder symptoms. IPT reduced depressive symptoms, hopelessness, and posttraumatic stress disorder symptoms, and increased rates of MDD remission relative to prison TAU alone. Effects on hopelessness were particularly strong. Cost per patient was $2,054 including costs for IPT training and supervision or $575 without these costs. For providers running their second or subsequent IPT group, cost per additional week in remission from MDD (relative to TAU alone) was $524 ($148 excluding training and supervision costs, which would not be needed for established programs). IPT is effective and cost-effective and we recommend its use for MDD among prisoners. It is currently the only treatment for MDD evaluated among incarcerated individuals.

Time-intensive behavioural activation for depression: A multiple baseline study. Depression is the second leading cause of disability, worldwide, and increasing access to its effective/preferred treatment requires more attention. Behavioural activation and time-intensive treatment delivery both show promise in this regard, yet research into their combination is limited. This study aimed to investigate the feasibility, effectiveness, and acceptability of time-intensive behavioural activation (BA) for depression METHODS: Eight adults with major depressive disorder were recruited from three outpatient IAPT services in London. The study employed a single case experimental design with multiple baselines. All participants completed time-intensive BA, consisting of up to seven twice weekly sessions with daily prompting in-between and three optional booster sessions. Idiographic, standardised and process measures of depression symptomatology were collected. Treatment recruitment and retention indicated that the intervention was feasible. Visual and statistical analyses showed that relative to baseline, 6 out of 8 participants made significant improvements in all idiographic symptoms of depression following the intervention. According to standardised measures of depression, four out of eight participants were considered treatment responders. Five participants completed follow-up measures and the majority of progress was maintained after the withdrawal of the intervention. The intervention was also considered highly acceptable by participants and therapists. Conclusions cannot be drawn about the generalizability or the long-term durability of the findings CONCLUSIONS: Overall this study provides new, but tentative evidence highlighting the potential of time-intensive BA as a feasible, effective and acceptable treatment for some adult outpatients with depression. The findings now warrant further, more rigorous evaluation of the treatment.

Treatment of depression and/or anxiety - outcomes of a randomised controlled trial of the tree theme method® versus regular occupational therapy. Depression and anxiety disorders are a major concern in western countries, and because these often have a negative affect on everyday life interventions based on activities in everyday life are needed. The Tree Theme Method® (TTM) is a client-centred occupational therapy intervention designed to increase the ability to cope with, and to enhance satisfaction with, everyday life, both at home and at work. The aim of this study was to compare the short term outcomes of the TTM intervention with regular occupational therapy treatment for people with depression and/or anxiety disorders. This randomised controlled trial included patients from three counties in Sweden. Men and women with depression and/or anxiety disorders, ages 18 to 65, were randomised to either TTM or regular occupational therapy. Assessment data were collected at baseline and the follow-up directly after completing the intervention. Non-parametric and parametric statistical methods were used. The questionnaires were answered by 118 patients at baseline and by 107 patients after completing the intervention. No significant differences in short term outcomes were found between the groups. Both groups showed positive significant outcomes regarding almost all aspects of activities in everyday life, psychological symptoms, and health-related and intervention-related aspects. Despite the lack of differences between the groups, the positive outcomes regarding activities in everyday life, psychological symptoms, and health-related aspects after completing the intervention indicates the need for further research on the long-term perspective of TTM compared to regular occupational therapy.

Nonpharmacological Treatment for Supporting Social Participation of Adults with Depression. Social withdrawal is predominantly seen among adults with depression. However, a dearth of reviews exists that explore nonpharmacological treatments, especially occupational therapy (OT) interventions and their effect in promoting social participation. The aim of this research was to review what intervention programs are conducted to support the social participation of adults with depression and their effectiveness. A systematic review was performed wherein relevant articles were searched in PubMed, CINAHL, Wiley Online Library, PsycINFO, and OTseeker databases and AJOT, BJOT, SJOT, and OTMH journals. Only English articles published from January 2010 to December 2018, which tackled intervention for adults aged 20-60 years with depression, were considered. Ten out of 918 studies met the screening criteria. Among the ten studies, the effective intervention programs were categorized as either occupation-based intervention (OBI) or cognitive behavioral therapy-based intervention (CBT-BI). These programs sought the following outcomes: behavioral change in social participation (n = 4), reduction of depression or depressive symptoms (n = 13), life satisfaction (n = 4), and quality of life (QoL) (n = 1). Studies showed moderate (n = 3) to strong (n = 7) level of certainty, whereas they also revealed high to unclear (n = 3) and low (n = 7) risk of bias. Both OBI such as animal-assisted therapy and CBT-BI such as behavioral change program and health education have a strong level of certainty and low risk of bias in promoting social participation by supporting positive behavioral change and reducing depressive symptoms. Furthermore, the sport and exercise program of OBI was popular in encouraging participation and engagement with other people. Other programs were suggested for combined interventions to support social participation, life satisfaction, and QoL.

Bibliotherapy as a treatment for depression in primary care. This study was designed to determine whether a physician-delivered bibliotherapy prescription would compare favorably with the prevailing usual care treatment for depression in primary care (that often involves medication) and potentially offer an alternative. Six family physicians were trained to write and deliver prescriptions for cognitive-behavioral bibliotherapy. Thirty-eight patients were randomly assigned to receive either usual care or a behavioral prescription to read the self-help book, Feeling Good (Burns, D. D. (1999). Feeling good: The new mood therapy. New York: HarperCollins). The treatment groups did not differ in terms of overall outcome variables. Patients in both treatment groups reported statistically significant decreases in depression symptoms, decreases in dysfunctional attitudes, and increases in quality of life. Although not statistically significant, the mean net medical expenses in the behavioral prescription group were substantially less. This study provided empirical evidence that a behavioral prescription for Feeling Good may be as effective as standard care, which commonly involves an antidepressant prescription.

Identifying moderators of the adherence-outcome relation in cognitive therapy for depression. Little is known about the influence of patients' pretreatment characteristics on the adherence-outcome relation in cognitive therapy (CT) for depression. In a sample of 57 depressed adults participating in CT, the authors examined interactions between pretreatment patient characteristics and therapist adherence in predicting session-to-session symptom change. Using items from the Collaborative Study Psychotherapy Rating Scale, the authors assessed 3 facets of therapist adherence: cognitive methods, negotiating/structuring, and behavioral methods/homework. Two graduate students rated Sessions 1-4 for adherence. Symptoms were assessed prior to each session with the Beck Depression Inventory-II. Moderators were assessed as part of patients' intake evaluations. After correcting for multiple comparisons, patient gender remained a significant moderator of the relationship between cognitive methods and next-session symptom change; cognitive methods more strongly predicted greater symptom improvement for women as compared to men. Pretreatment anxiety and number of prior depressive episodes were significant moderators of the relationship between behavioral methods/homework and next-session symptom change, with greater behavioral methods/homework predicting symptom improvement more strongly among patients high in pretreatment anxiety and among patients with relatively few prior depressive episodes. This is the first study to provide evidence of how therapist adherence is differentially related to outcome among depressed patients with different characteristics. If replicated, these findings may inform clinical decisions regarding the use of specific facets of adherence in CT for depression with specific patients.

Four hygienic-dietary recommendations as add-on treatment in depression: a randomized-controlled trial. Modifying diet, exercise, sunlight exposure and sleep patterns may be useful in the treatment of depression. Eighty nonseasonal depressive outpatients on anti-depressant treatment were randomly assigned either to the active or control group. Four hygienic-dietary recommendations were prescribed together. Outcome measures were blinded assessed before and after the six month intervention period. A better evolution of depressive symptoms, a higher rate of responder and remitters and a lesser psychopharmacological prescription was found in the active group. Small sample size. Lacked homogeneity concerning affective disorders (major depression, dysthimia, bipolar depression). This study suggests lifestyle recommendations can be used as an effective antidepressant complementary strategy in daily practice.

The Appalachia Mind Health Initiative (AMHI): a pragmatic randomized clinical trial of adjunctive internet-based cognitive behavior therapy for treating major depressive disorder among primary care patients. Major depressive disorder (MDD) is a leading cause of disease morbidity. Combined treatment with antidepressant medication (ADM) plus psychotherapy yields a much higher MDD remission rate than ADM only. But 77% of US MDD patients are nonetheless treated with ADM only despite strong patient preferences for psychotherapy. This mismatch is due at least in part to a combination of cost considerations and limited availability of psychotherapists, although stigma and reluctance of PCPs to refer patients for psychotherapy are also involved. Internet-based cognitive behaviorial therapy (i-CBT) addresses all of these problems. Enrolled patients (n = 3360) will be those who are beginning ADM-only treatment of MDD in primary care facilities throughout West Virginia, one of the poorest and most rural states in the country. Participating treatment providers and study staff at West Virginia University School of Medicine (WVU) will recruit patients and, after obtaining informed consent, administer a baseline self-report questionnaire (SRQ) and then randomize patients to 1 of 3 treatment arms with equal allocation: ADM only, ADM + self-guided i-CBT, and ADM + guided i-CBT. Follow-up SRQs will be administered 2, 4, 8, 13, 16, 26, 39, and 52 weeks after randomization. The trial has two primary objectives: to evaluate aggregate comparative treatment effects across the 3 arms and to estimate heterogeneity of treatment effects (HTE). The primary outcome will be episode remission based on a modified version of the patient-centered Remission from Depression Questionnaire (RDQ). The sample was powered to detect predictors of HTE that would increase the proportional remission rate by 20% by optimally assigning individuals as opposed to randomly assigning them into three treatment groups of equal size. Aggregate comparative treatment effects will be estimated using intent-to-treat analysis methods. Cumulative inverse probability weights will be used to deal with loss to follow-up. A wide range of self-report predictors of MDD heterogeneity of treatment effects based on previous studies will be included in the baseline SRQ. A state-of-the-art ensemble machine learning method will be used to estimate HTE. The study is innovative in using a rich baseline assessment and in having a sample large enough to carry out a well-powered analysis of heterogeneity of treatment effects. We anticipate finding that self-guided and guided i-CBT will both improve outcomes compared to ADM only. We also anticipate finding that the comparative advantages of adding i-CBT to ADM will vary significantly across patients. We hope to develop a stable individualized treatment rule that will allow patients and treatment providers to improve aggregate treatment outcomes by deciding collaboratively when ADM treatment should be augmented with i-CBT.

STEP.De study-a multicentre cluster-randomised effectiveness trial of exercise therapy for patients with depressive symptoms in healthcare services: study protocol. Although exercise therapy has widely been shown to be an efficacious treatment modality for depression, evidence for its effectiveness and cost efficiency is lacking. The Sport/Exercise Therapy for Depression study is a multicentre cluster-randomised effectiveness trial that aims to compare the effectiveness and cost efficiency of exercise therapy and psychotherapy as antidepressant treatment. 480 patients (aged 18-65) with an International Classification of Diseases diagnosis associated with depressive symptoms are recruited. Up to 30 clusters (psychotherapists) are randomly assigned to allocate patients to either an exercise or a psychotherapy treatment as usual in a 2:1 ratio. The primary outcome (depressive symptoms) and the secondary outcomes (work and social adjustment, quality of life) will be assessed at six measurement time points (t0: baseline, t1: 8 weeks after treatment initiation, t2: 16 weeks after treatment initiation, t3/4/5: 2, 6, 12 months after treatment). Linear regression analyses will be used for the primary endpoint data analysis. For the secondary endpoints, mixed linear and logistic regression models with fixed and random factors will be added. For the cost efficiency analysis, expenditures in the 12 months before and after the intervention and the outcome difference will be compared between groups in a multilevel model. Recruitment start date was 1 July 2018 and the planned recruitment end date is 31 December 2020. The study protocol was approved by the ethics committee of the University of Potsdam (No. 17/2018) and the Freie Universität Berlin (No. 206/2018) and registered in the ISRCTN registry. Informed written consent will be obtained from all participants. The study will be reported in accordance with the Consolidated Standards of Reporting Trials and the Recommendations for Interventional Trials statements. The results will be published in peer-reviewed academic journals and disseminated to the public. ISRCTN28972230.

The Generalizability of Randomized Controlled Trials of Self-Guided Internet-Based Cognitive Behavioral Therapy for Depressive Symptoms: Systematic Review and Meta-Regression Analysis. Self-guided internet-based cognitive behavioral therapies (iCBTs) for depressive symptoms may substantially increase accessibility to mental health treatment. Despite this, questions remain as to the generalizability of the research on self-guided iCBT. We sought to describe the clinical entry criteria used in studies of self-guided iCBT, explore the criteria's effects on study outcomes, and compare the frequency of use of these criteria with their use in studies of face-to-face psychotherapy and antidepressant medications. We hypothesized that self-guided iCBT studies would use more stringent criteria that would bias the sample toward those with a less complex clinical profile, thus inflating treatment outcomes. We updated a recently published meta-analysis by conducting a systematic literature search in PubMed, MEDLINE, PsycINFO, and EMBASE. We conducted a meta-regression analysis to test the effect of the different commonly used psychiatric entry criteria on the treatment-control differences. We also compared the frequency with which exclusion criteria were used in the self-guided iCBT studies versus studies of face-to-face psychotherapy and antidepressants from a recently published review. Our search yielded 5 additional studies, which we added to the 16 studies identified by Karyotaki and colleagues in 2017. Few self-guided iCBT studies excluded patients with severe depressive symptoms (6/21, 29%), but self-guided iCBT studies were more likely than antidepressant (14/170, 8.2%) studies to use this criterion. However, self-guided iCBT studies did not use this criterion more frequently than face-to-face psychotherapy studies (6/16, 38%). Beyond this, we found no evidence that self-guided iCBTs used more stringent entry criteria. Strong evidence suggested that they were actually less likely to use most entry criteria, especially exclusions on the basis of substance use or personality pathology. None of the entry criteria used had an effect on outcomes. A conservative interpretation of our findings is that the patient population sampled in the literature on self-guided iCBT is relatively comparable with that of studies of antidepressants or face-to-face psychotherapy. Alternatively, studies of unguided cognitive behavioral therapy may sample from a more heterogeneous and representative patient population. Until evidence emerges to suggest otherwise, the patient population sampled in self-guided iCBT studies cannot be considered as less complex than the patient population from face-to-face psychotherapy or antidepressant studies.

Web-based cognitive behavior therapy for depression with and without telephone tracking in a national helpline: secondary outcomes from a randomized controlled trial. An earlier report indicated that callers to a telephone counseling service benefited from the addition of an evidence-based Web intervention for depression. It is not known whether the Web intervention would also lower alcohol use and stigma, or improve quality of life and knowledge of depression and its treatments. To report the secondary outcomes of a trial of a Web-based cognitive behavior therapy (CBT) intervention for depression, including hazardous alcohol use, quality of life, stigma, depression literacy, and CBT literacy. We recruited a sample of 155 callers to Lifeline, a national telephone counseling service in Australia, who met the criteria for moderate to high psychological distress. Participants were randomly assigned to 1 of 4 conditions: (1) Web CBT plus weekly telephone tracking, (2) Web CBT only, (3) weekly telephone tracking only, and (4) neither Web CBT nor telephone tracking. Participants were assessed at preintervention, postintervention, and 6 and 12 months postintervention. At postintervention, participants who completed the Web intervention either with or without telephone support had lower levels of hazardous alcohol use (without tracking: P = .008, effect size = 0.23; with tracking: P = .003, effect size = 0.26), improved quality of life (without tracking: P = .001, effect size = 0.81; with tracking: P = .009, effect size = 0.63), and improved CBT literacy (without tracking: P = .01, effect size = 0.71; with tracking: P < .001, effect size = 0.80) compared with those who did not receive the Web intervention or telephone support. Results for quality of life and CBT literacy were maintained at 6- and 12-month's follow-up, but differences in hazardous alcohol use were not significantly different between conditions at 6 and 12 months. Although omnibus tests for depression literacy and stigma were nonsignificant, contrasts revealed that those in the Web-only condition showed significantly lower levels of stigma than participants in the control condition at postintervention. This was true for participants in the Web-only and Web plus tracking conditions at 6 months. Similarly, those in the Web-only and Web plus tracking conditions had significantly higher depression literacy at postintervention, and this was maintained in the Web-only condition at 6-months' follow-up. No significant differences were found in depression literacy and stigma between conditions at 12 months. Evidence-based Web interventions for depression can be effective not only in reducing depression symptoms but also in improving other health outcomes, including quality of life, hazardous alcohol use, and knowledge about effective strategies for depression self-management.

The efficacy and optimal matching of an Internet-based acceptance and commitment therapy intervention for depressive symptoms among university students: A randomized controlled trial in China. The present study tested the efficacy of an unguided internet-based Acceptance and Commitment Therapy (iACT) program for depression, and identified the psychological characteristics of participants who benefitted the most from the program. Undergraduate students with mild to severe symptoms of depression were randomized to the iACT group (n=95) or the waiting-list group (WLC group; n=87). Depressive symptoms and positive mental health were assessed at baseline (T0 ), at the end of the 6-week program (T1 ), and at a 3-month follow-up (T2 ). Compared with the WLC group, the iACT group showed significantly more improvement in depressive symptoms (d=1.27) and positive mental health (d=0.59), both at T1 and T2 . Latent Profile Analysis identified three classes of participants: Sensitive-to-Relationship, Low-Reactive-Depression, and Endogenous-Depression group. In general, the treatment was particularly suitable for the Sensitive-to-Relationship class. The iACT was effective in treating the depressive symptoms of undergraduates, especially suitable for the clients with high baseline depression, high externality, high resistance, and high sensitivity to relationships.

Cost-Utility Analysis of Mindfulness-Based Cognitive Therapy Versus Antidepressant Pharmacotherapy for Prevention of Depressive Relapse in a Canadian Context: Analyse coût-utilité de la thérapie cognitive basée sur la pleine conscience contre la pharmacothérapie antidépressive pour prévenir la rechute de la dépression en contexte canadien. Patients suffering from major depressive disorder (MDD) experience impaired functioning and reduced quality of life, including an elevated risk of episode return. MDD is associated with high societal burden due to increased healthcare utilization, productivity losses, and suicide-related costs, making the long-term management of this illness a priority. The purpose of this study is to evaluate the cost-effectiveness of mindfulness-based cognitive therapy (MBCT), a first-line preventative psychological treatment, compared to maintenance antidepressant medication (ADM), the current standard of care. A cost-utility analysis was conducted over a 24-month time horizon to model differences between MBCT and ADM in cost and quality-adjusted life years (QALY). The analysis was conducted using a decision tree analytic model. Intervention efficacy, utility, and costing data estimates were derived from published sources and expert consultation. MBCT was found to be cost-effective compared to maintenance ADM over a 24-month time horizon. Antidepressant pharmacotherapy resulted in 1.10 QALY and $17,255.37 per patient on average, whereas MBCT resulted in 1.18 QALY and $15,030.70 per patient on average. This resulted in a cost difference of $2,224.67 and a QALY difference of 0.08, in favor of MBCT. Multiple sensitivity analyses supported these findings. From both a societal and health system perspective, utilizing MBCT as a first-line relapse prevention treatment is potentially cost-effective in a Canadian setting. Future economic evaluations should consider combined treatment (e.g., ADM and psychotherapy) as a comparator and longer time horizons as the literature advances.

A DILEMMA-FOCUSED INTERVENTION FOR DEPRESSION: A MULTICENTER, RANDOMIZED CONTROLLED TRIAL WITH A 3-MONTH FOLLOW-UP. Since long ago it has been asserted that internal conflicts are relevant to the understanding and treatment of mental disorders, but little research has been conducted to support the claim. The aim of this study was to test the differential efficacy of group cognitive behavioral therapy (CBT) plus an intervention focused on the dilemma(s) detected for each patient versus group individual CBT plus individual CBT for treating depression. A comparative controlled trial with a 3-month follow-up was conducted. One hundred twenty-eight adults meeting criteria for MDD and/or dysthymia, presenting at least one cognitive conflict (implicative dilemma or dilemmatic construct, assessed by the repertory grid technique) and who had completed seven sessions of group CBT were randomly assigned to eight sessions of individual manualized CBT or dilemma-focused therapy (DFT). The Beck Depression Inventory-II was administered at baseline, at the end of therapy and after 3 months' follow-up. Multilevel mixed effects modeling yielded no significant differences between CBT and DFT with the intention-to-treat sample. Equivalent effect sizes, remission, and response rates were found with completers as well. In combination with group CBT, both individual CBT and DFT significantly reduced depressive symptoms. Both conditions obtained comparable results to those in the literature. Thus, the superiority of the adjunctive DFT was not demonstrated. Working with dilemmas can be seen as a promising additional target in the psychotherapy of depression, but further research is still required.

Efficacy of cognitive-behavioural therapy and other psychological treatments for adult depression: meta-analytic study of publication bias. It is not clear whether the effects of cognitive-behavioural therapy and other psychotherapies have been overestimated because of publication bias. To examine indicators of publication bias in randomised controlled trials of psychotherapy for adult depression. We examined effect sizes of 117 trials with 175 comparisons between psychotherapy and control conditions. As indicators of publication bias we examined funnel plots, calculated adjusted effect sizes after publication had been taken into account using Duval & Tweedie's procedure, and tested the symmetry of the funnel plots using the Begg & Mazumdar rank correlation test and Egger's test. The mean effect size was 0.67, which was reduced after adjustment for publication bias to 0.42 (51 imputed studies). Both Begg & Mazumbar's test and Egger's test were highly significant (P<0.001). The effects of psychotherapy for adult depression seem to be overestimated considerably because of publication bias.

The clinical effectiveness of cognitive therapy for depression in an outpatient clinic. Cognitive therapy (CT) has been shown to be efficacious in the treatment of depression in numerous randomized controlled trials (RCTs). However, little evidence is available that speaks to the effectiveness of this treatment under routine clinical conditions. This paper examines outcomes of depressed individuals seeking cognitive therapy at an outpatient clinic (N=217, Center for Cognitive Therapy; CCT). Outcomes were then compared to those of participants in a large NIMH-funded RCT of cognitive therapy and medications as treatments for depression. The CCT is shown to be a clinically representative setting, and 61% of participants experienced reliable change in symptoms over the course of treatment; of those, 45% (36% of the total sample) met criteria for recovery by the end of treatment. Participants at CCT had similar outcomes to participants treated in the RCT, but there was some evidence that those with more severe symptoms at intake demonstrated greater improvement in the RCT than their counterparts at CCT. The CCT may not be representative of all outpatient settings, and the structure of treatment there was considerably different from that in the RCT. Treatment fidelity was not assessed at CCT. Depressed individuals treated with cognitive therapy in a routine clinical care setting showed a significant improvement in symptoms. When compared with outcomes evidenced in RCTs, there was little evidence of superior outcomes in either setting. However, for more severe participants, outcomes were found to be superior when treatment was delivered within an RCT than in an outpatient setting. Clinicians treating such patients in non-research settings may thus benefit from making modifications to treatment protocols to more closely resemble research settings.

Feasibility study of an interactive multimedia electronic problem solving treatment program for depression: a preliminary uncontrolled trial. Computer-based depression interventions lacking live therapist support have difficulty engaging users. This study evaluated the usability, acceptability, credibility, therapeutic alliance and efficacy of a stand-alone multimedia, interactive, computer-based Problem Solving Treatment program (ePST™) for depression. The program simulated live treatment from an expert PST therapist, and delivered 6 ePST™ sessions over 9weeks. Twenty-nine participants with moderate-severe symptoms received the intervention; 23 completed a minimally adequate dose of ePST™ (at least 4 sessions). Program usability, acceptability, credibility, and therapeutic alliance were assessed at treatment midpoint and endpoint. Depressive symptoms and health-related functioning were assessed at baseline, treatment midpoint (4weeks), and study endpoint (10weeks). Depression outcomes and therapeutic alliance ratings were also compared to previously published research on live PST and computer-based depression therapy. Participants rated the program as highly usable, acceptable, and credible, and reported a therapeutic alliance with the program comparable to that observed in live therapy. Depressive symptoms improved significantly over time. These findings also provide preliminary evidence that ePST™ may be effective as a depression treatment. Larger clinical trials with diverse samples are indicated.

An effectiveness trial of group cognitive behavioral therapy for patients with persistent depressive symptoms in substance abuse treatment. Although depression frequently co-occurs with substance abuse, few individuals entering substance abuse treatment have access to effective depression treatment. The Building Recovery by Improving Goals, Habits, and Thoughts (BRIGHT) study is a community-based effectiveness trial that compared residential substance abuse treatment with residential treatment plus group cognitive behavioral therapy for depression delivered by substance abuse treatment counselors. We hypothesized that intervention clients would have improved depression and substance use outcomes compared with those of clients receiving usual care. A nonrandomized controlled trial using a quasi-experimental intent-to-treat design in which 4 sites were assigned to alternate between the intervention and usual care conditions every 4 months for 2½ years. Four treatment programs in Los Angeles County. We screened 1262 clients for persistent depressive symptoms (Beck Depression Inventory-II score >17). We assigned 299 clients to receive either usual care (n = 159) or usual care plus the intervention (n = 140). Follow-up rates at 3 and 6 months after the baseline interview were 88.1% and 86.2%, respectively, for usual care and 85.7% and 85.0%, respectively, for the intervention group. Sixteen 2-hour group sessions of cognitive behavioral therapy for depression. Change in depression symptoms, mental health functioning, and days of alcohol and problem substance use. Intervention clients reported significantly fewer depressive symptoms (P < .001 at 3 and 6 months) and had improved mental health functioning (P < .001 at 3 months and P < .01 at 6 months). At 6 months, intervention clients reported fewer drinking days (P < .05) and fewer days of problem substance use (P < .05) on days available. Providing group cognitive behavioral therapy for depression to clients with persistent depressive symptoms receiving residential substance abuse treatment is associated with improved depression and substance use outcomes. These results provide support for a new model of integrated care. clinicaltrials.gov Identifier: NCT01191788.

Feasibility, acceptability and future adaptation of the Chinese translated Behavioural activation (C-BA) treatment for depression: A pilot study. Although depression is prevalent among Chinese international students (CIS), only 4% of CIS seek treatment. Behavioural activation (BA) has been suggested as a culturally sensitive treatment for depression that has the potential to meet the clinical needs of CIS. The current pilot study tested the feasibility, acceptability and themes for future cultural adaptations of a Chinese translated BA treatment (C-BA) among CIS. Six CIS with elevated depressive symptoms (Beck Depression Inventory, BDI ≥14) completed a six-session individual C-BA treatment and assessments at pre- and post-treatment and a 1-month follow-up. Primary outcome measures included treatment feasibility, acceptability and qualitative interview data informing future adaption of C-BA. Exploratory analyses examined group changes in depressive symptoms over time and clinically significant symptom changes on individual levels. All participants found the treatment to be highly feasible and culturally acceptable, and were highly engaged in the treatment. Themes of future cultural adaptions were generated from the qualitative interviews. Significant decreases in depressive symptoms were observed at a one1-month post-treatment follow-up assessment. Preliminary evidence suggests that C-BA has the potential to be a culturally sensitive treatment for depression among CIS. CIS demonstrated openness to psychotherapy and high treatment engagement.

Art therapy for patients with depression: expert opinions on its main aspects for clinical practice. Art therapy is based mainly on clinical experience and is rarely described and evaluated scientifically. There is a need for further exploration of its use in patients with depression. The aim of this study was to explore what experts consider to be the main aspects of art therapy in clinical practice for patients with depression. Eighteen occupational therapists experienced and educated in art therapy participated. The experts answered three rounds of Delphi questionnaires and ranked their agreement with 74 assertions. Consensus was defined as 70% or higher. The experts agreed more on assertions about theoretical frames of reference than about clinical practice. The main aspects of art therapy were agreed to be the patients' opportunity to express themselves verbally and through making art. It was equally important that art tasks provided an opportunity to address depressive thoughts, feelings, life experiences, and physical symptoms. Experts in the field of art therapy considered that the main aspect of clinical practice in art therapy for patients with depression is that art themes should promote expression related to both to depression and personal history.

Psychological Treatment of Depression in Primary Care: Recent Developments. We give an overview of recent developments on psychological treatments of depression in primary care. In recent years, it has become clear that psychotherapies can effectively be delivered through e-health applications. Furthermore, several studies in low and middle income countries have shown that lay health counselors can effectively deliver psychological therapies. Behavioral activation, a relatively simple form of therapy, has been found to be as effective as cognitive behavior therapy. Treatment of subthreshold depression has been found to not only reduce depressive symptoms but also prevent the onset of major depression. In addition, therapies are effective in older adults, patients with general medical disorders and in perinatal depression. Psychological therapies are effective in the treatment of depression in primary care, have longer lasting effects than drugs, are preferred by the majority of patients, and can be applied flexibly with different formats and across different target groups.

[Behavioral activation and depression: a contextual treatment approach]. Depression is a widespread psychological disorder that affects approximately one in five North American. Typical reactions to depression include inactivity, isolation, and rumination. Several treatments and psychological interventions have emerged to address this problematic. Cognitive behavioural therapies have received increasingly large amounts of empirical support. A sub-component of cognitive behavioural therapy, behavioural activation, has been shown to in itself effectively treat symptoms of depression. This intervention involves efforts to re-activate the depressed client by having them engage in pleasant, gratifying, leisure, social, or physical activities, thereby counteracting the tendency to be inactive and to isolate oneself. Clients are guided through the process of establishing a list of potentially rewarding social, leisure, mastery-oriented or physical activities, to then establish a gradual hierarchy of objectives to be accomplished over the span of several weeks. Concrete action plans are devised, and solutions to potential obstacles are elaborated. The client is the asked to execute the targeted objective and to record their mood prior to and following the activity. Behavioural activation effectively reverses the downward spiral to depression. Interestingly, studies show that behavioural activation has a positive effect on cognitive activities. It has been shown to reduce rumination and favour cognitive restructuring, without requiring cognitively-based interventions. The advantage of this treatment is therefore that it is simpler to administer in comparison to full-packaged cognitive behavioural therapies, it requires a lesser number of sessions and can be disseminated in a low-intensity format. This article begins by summarizing the origins of the behavioural model of depression, which serves as a basis to the understanding of behavioural activation. This is followed by a detailed explanation of the different phases involved in a behavioural activation intervention. Empirical support for behavioural activation is then presented in regards to depression as well as comorbid physical and psychological health problems. The results of meta-analyses and randomized controlled trials are presented. Behavioural activation is then discussed within the framework of third-wave therapies, discussing the potential role of mindfulness in behavioural activation objectives. Specifically, it is suggested that mindfulness, although not necessarily directly addressed in behavioural activation interventions, is an integral part of this intervention as clients are asked to record their mood and activities and to become cognizant of the relationship between their symptoms of depression and the participation in activities that provide positive reinforcement. This favours self-awareness and allows clients to realize the impact of their actions on their physical and psychological states. In engaging in self-observation and self-recording, and in participating in a variety of tasks and activities, clients are indirectly encouraged to focus on the here and now rather that to succumb to the depressive tendency that is to ruminate. Suggestions are made as to how therapists can include mindfulness-based activities in the behavioural activation hierarchy. It is hypothesized that, due to the calming effect of mindfulness practices on the nervous system, incorporating mindfulness-based activities-such as yoga, tai chi, Qi Gong, or meditation-could for some people enhance the efficacy of behavioural activation interventions and foster a greater sense of well-being. The article concludes by discussing issues that should be addressed in future research. It is suggested that future studies on behavioural activation explore the impacts of incorporating mindfulness-based activities in the behavioural activation hierarchy in comparison to a traditional hierarchy limited to the accomplishment of gratifying or mastery-oriented tasks, social outings, leisure activities and physical activity.

Effects of Scheduled Waiting for Psychotherapy in Patients With Major Depression. The role of nonspecific factors in the outcome of psychotherapy is poorly understood. To study the effects of pretreatment expectancy of scheduled psychotherapy, we examined the effects of an agreed waiting time on the outcome of psychodynamic psychotherapy. Thirty-three treatment-naive outpatients with major depressive disorder were randomly selected to start psychotherapy either directly (DG; n = 17) or after waiting for 6 months (WG; n = 16). In WG, 18% to 60% of the total decline in symptoms took place during the waiting time. After 1 year of active psychotherapy, the anxiety score declined significantly only in WG, and the total length of treatment needed was shorter in WG. No other outcome differences between WG and DG were found. We conclude that scheduled waiting associates with a significant decline in depressive symptoms. Scheduled waiting should be regarded as a preparatory treatment and not as an inert nontreatment control.

The Effectiveness of Cognitive Behavioral Therapy versus Psychoeducation in the Management of Depression among Patients Undergoing Haemodialysis. The aim of this randomized controlled trial was to compare the effectiveness of psychoeducation versus cognitive behavioral therapy (CBT) in the management of depression among renal dialysis patients. A sample of 130 dialysis patients participated in the study and they were assigned at random to one of two therapies: psychoeducation (N = 65) or CBT (N = 65). Hamilton depression rating scale was completed by the participants in both groups prior to the therapies and after completion. Both therapies were effective in the management of depression, although psychoeducation was superior. Psychoeducation is recommended over CBT in the management of depression among renal dialysis patients.

Psychological treatments for persistent depression: A systematic review and meta- analysis of quality of life and functioning outcomes: Correction to McPherson and Senra (2022). Reports an error in "Psychological treatments for persistent depression: A systematic review and meta-analysis of quality of life and functioning outcomes" by Susan McPherson and Hugo Senra (Psychotherapy, Advanced Online Publication, Jun 27, 2022, np). In the article, there were errors in the abstract. The confidence interval in the sentence Quality of life at follow-up: pooled g = 0.21 should appear as follows: 95% CI, 0.10-0.32. In the sentence The psychological interventions were associated with improvements in patients' functioning at end-of-treatment, the pooled g should appear as g = 0.35. The confidence interval in the sentence Functioning at follow-up resulted in: pooled g = 0.33 should appear as follows: 95% CI, 0.15-0.51. Figure 5 also has been corrected. All versions of this article have been corrected. (The following abstract of the original article appeared in record 2022-76312-001.) To date it is unclear whether psychological therapies have potential to improve quality of life and functioning in patients with persistent depression. This meta-analysis examines the effect of psychological therapies for improving quality of life and functioning in patients with persistent forms of depression. Data sources include Medline and Meta-Analytic Psychotherapy Database (METAPSY), searched 07/2021. Eligible studies were randomized controlled trials where participants had major depressive disorder on entry and met criteria for a persistent form of depression, for example, chronic, treatment resistant or recurrent depression. Standardized mean differences (Hedge's g) were calculated in random-effects meta-analyses. Fourteen studies met inclusion criteria (N = 1898). Psychological interventions were associated with improvements in patients' quality of life at the end of treatment: pooled g = 0.24 (95% confidence intervals [CIs] 0.13-0.34); low to moderate levels of heterogeneity (I² = 0% [95% CI 0%-41.2%]). Quality of life at follow-up: pooled g = 0.21 (95% CI 0.01-0.32); low to high levels of heterogeneity considering the wide CI for I² (I² = 10.36% [95% CI 0%-77.5%]). The psychological interventions were associated with improvements in patients' functioning at end of treatment: pooled g = 0.34 (95% CI 0.21-0.48); low to high levels of heterogeneity considering the wide CI for I² (I² = 0% [95% CI 0%-81.7%]). Functioning at follow-up resulted in: pooled g = 0.33 (95% CI 0.15-0.50); low to high levels of heterogeneity considering the wide CI for I² (I² = 0% [95% CI 0%-86.2%]). This meta-analysis highlights the potential benefits of psychological therapies for improving quality of life and functioning in patients with persistent depression, with strongest long-term effects for mindfulness-based cognitive therapy, interpersonal therapy in combination with antidepression medication, and long-term psychoanalytic psychotherapy.

Effectiveness of interpersonal psychotherapy for community living depressed women involved with the justice system. Despite the prevalence of depression among women in the justice system, and its potentially significant consequences, there is a dearth of studies investigating psychological treatments for depression in this context, especially outside prison. Our aim was to gather preliminary data on whether individual interpersonal psychotherapy (IPT) is an acceptable and effective treatment for depression in women at an early stage in the justice system. In this pilot study, IPT was offered to 24 depressed women following their first or second contact with the justice system. The women were assessed using a range of scales to quantify depression, anxiety, post-traumatic stress disorder (PTSD) and social support. Multilevel models were used to explore interactions between change in depression and other features given the multiplicity and complexity of problems. Details on engagement and attrition were also collected. Therapy attrition was low, despite challenging life-circumstances and depression scores followed a linear trajectory with scores significantly decreasing over the time (β = -0.59, SE = 0.07, p < 0.001). Participants with more adverse life events, attachment related anxiety and lower social support had poorer outcomes. Results are encouraging. More than half of the hard-to-reach women who were eligible did engage, and retention rates suggest the therapy was acceptable to them. Depression scores improved, and potential factors affecting treatment outcome were identified. A randomised controlled trial is now warranted, ensuring adequate supplementary support for women with dependants living on their own and without employment.

Psychological therapies for preventing seasonal affective disorder. Seasonal affective disorder (SAD) is a seasonal pattern of recurrent major depressive episodes that most commonly occurs during autumn or winter and remits in spring. The prevalence of SAD ranges from 1.5% to 9%, depending on latitude. The predictable seasonal aspect of SAD provides a promising opportunity for prevention. This is one of four reviews on the efficacy and safety of interventions to prevent SAD; we focus on psychological therapies as preventive interventions. To assess the efficacy and safety of psychological therapies (in comparison with no treatment, other types of psychological therapy, second-generation antidepressants (SGAs), light therapy, melatonin or agomelatine or lifestyle interventions) in preventing SAD and improving patient-centred outcomes among adults with a history of SAD. We conducted a search of the Cochrane Depression, Anxiety and Neurosis Review Group Specialised Register (CCDANCTR) to 11 August 2015. The CCDANCTR contains reports of relevant randomised controlled trials from EMBASE (1974 to date), MEDLINE (1950 to date), PsycINFO (1967 to date) and the Cochrane Central Register of Controlled Trials (CENTRAL). Furthermore, we searched the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Knowledge, The Cochrane Library and the Allied and Complementary Medicine Database (AMED) (to 26 May 2014). We conducted a grey literature search (e.g. in clinical trial registries) and handsearched the reference lists of all included studies and pertinent review articles. To examine efficacy, we planned to include randomised controlled trials on adults with a history of winter-type SAD who were free of symptoms at the beginning of the study. To examine adverse events, we intended to include non-randomised studies. We planned to include studies that compared psychological therapy versus any other type of psychological therapy, placebo, light therapy, SGAs, melatonin, agomelatine or lifestyle changes. We also intended to compare psychological therapy in combination with any of the comparator interventions listed above versus the same comparator intervention as monotherapy. Two review authors screened abstracts and full-text publications against the inclusion criteria. Two review authors planned to independently extract data and assess risk of bias. We planned to pool data for meta-analysis when participant groups were similar and when studies assessed the same treatments versus the same comparator and provided similar definitions of outcome measures over a similar duration of treatment; however, we included no studies. We identified 2986 citations through electronic searches and reviews of reference lists after de-duplication of search results. We excluded 2895 records during title and abstract review and assessed 91 articles at full-text review for eligibility. We found no controlled studies on use of psychological therapy to prevent SAD and improve patient-centred outcomes in adults with a history of SAD. Presently, there is no methodologically sound evidence available to indicate whether psychological therapy is or is not an effective intervention for prevention of SAD and improvement of patient-centred outcomes among adults with a history of SAD. Randomised controlled trials are needed to compare different types of psychological therapies and to compare psychological therapies versus placebo, light therapy, SGAs, melatonin, agomelatine or lifestyle changes for prevention of new depressive episodes in patients with a history of winter-type SAD.

Predicting early dropout in online versus face-to-face guided self-help: A machine learning approach. Early dropout hinders the effective adoption of brief psychological interventions and is associated with poor treatment outcomes. This study examined if attendance and depression treatment outcomes could be improved by matching patients to either face-to-face or computerized low-intensity psychological interventions. Archival clinical records were analysed for 85,664 patients who accessed face-to-face or computerized guided self-help (GSH). The primary outcome was early dropout (attending ≤3 sessions). Supervised machine learning analyses were applied in a training sample (n = 55,529). The trained algorithm was cross-validated in an independent test sample (n = 30,135). The clinical utility of the model was evaluated using logistic regression, chi-square tests, and sensitivity analyses in a balanced subsample. Patients who received their model-indicated treatment modality were 12% more likely to receive an adequate dose of treatment OR = 1.12 (95% CI = 1.02 to 1.24), p = .02, and the strength of this effect was larger in the balanced subsample (OR = 2.10, 95% CI = 1.65 to 2.68, p < .001). Patients had better treatment outcomes when matched to their model-indicated treatment modality. Machine learning approaches may enable services to optimally match patients to the treatment modality that maximizes attendance.

Reducing Stress and Preventing Depression (RESPOND): Randomized Controlled Trial of Web-Based Rumination-Focused Cognitive Behavioral Therapy for High-Ruminating University Students. Prevention of depression is a priority to reduce its global disease burden. Targeting specific risk factors, such as rumination, may improve prevention. Rumination-focused Cognitive Behavioral Therapy (RFCBT) was developed to specifically target depressive rumination. The primary objective of this study was to test whether guided Web-based RFCBT (i-RFCBT) would prevent the incidence of major depression relative to usual care in UK university students. The secondary objective was to test the feasibility and estimated effect sizes of unguided i-RFCBT. To address the primary objective, a phase III randomized controlled trial was designed and powered to compare high risk university students (N=235), selected with elevated worry/rumination, recruited via an open access website in response to circulars within universities and internet advertisements, randomized to receive either guided i-RFCBT (interactive Web-based RFCBT, supported by asynchronous written Web-based support from qualified therapists) or usual care control. To address the secondary objective, participants were also randomized to an adjunct arm of unguided (self-administered) i-RFCBT. The primary outcome was the onset of a major depressive episode over 15 months, assessed with structured diagnostic interviews at 3 (postintervention), 6, and 15 months post randomization, conducted by telephone, blind to the condition. Secondary outcomes of symptoms of depression and anxiety and levels of worry and rumination were self-assessed through questionnaires at baseline and the same follow-up intervals. Participants were randomized to guided i-RFCBT (n=82), unguided i-RFCBT (n=76), or usual care (n=77). Guided i-RFCBT reduced the risk of depression by 34% relative to usual care (hazard ratio [HR] 0.66, 95% CI 0.35 to 1.25; P=.20). Participants with higher levels of baseline stress benefited most from the intervention (HR 0.43, 95% CI 0.21 to 0.87; P=.02). Significant improvements in rumination, worry, and depressive symptoms were found in the short-to-medium term. Of the 6 modules, guided participants completed a mean of 3.46 modules (SD 2.25), with 46% (38/82) being compliant (completing ≥4 modules). Similar effect sizes and compliance rates were found for unguided i-RFCBT. Guided i-RFCBT can reduce the onset of depression in high-risk young people reporting high levels of worry/rumination and stress. The feasibility study argues for formally testing unguided i-RFCBT for prevention: if the observed effect sizes are robustly replicated in a phase III trial, it has potential as a scalable prevention intervention.

Sudden gains in cognitive-behavior therapy for treatment-resistant depression: Processes of change. Sudden gains were investigated in cognitive-behavioral therapy (CBT) for treatment-resistant depression (TRD). Client and therapist processes in sessions proximal to sudden gains were examined to better understand the antecedents of sudden gains and potential mechanisms linking them to outcome. Participants were 156 adults with TRD in a randomized controlled trial of CBT as an adjunct to pharmacotherapy (Wiles et al., 2013). Depression symptoms were assessed by the Beck Depression Inventory-II at each session. In a subsample of 50 clients, audio-recordings of 125 therapy sessions were rated for hope, emotional processing, and therapist competence in case-conceptualization. Sudden gains were experienced by 54% of participants. Those with gains reported significantly lower depression severity at 12-month follow-up and more remission of symptoms than those without gains. Sudden gains also predicted lower depression at follow-up, beyond the slope of linear change in symptoms across treatment. Therapists demonstrated greater competence in case conceptualization with clients who reported sudden gains, and those with gains expressed more hope in sessions prior to a gain. In addition, more hope and emotional processing in the pregain sessions predicted less depression at follow-up, controlling for depression scores in the prior session. Better therapist conceptualization skills and more client hope in the baseline and pregain sessions were also associated with more emotional processing in those same sessions. This study extends the phenomenon of sudden gains in CBT for depression to a treatment-resistant population and identified important therapy processes that predicted long-term outcomes: hope and emotional processing.

Cognitive bias modification to prevent depression (COPE): results of a randomised controlled trial. Although efficacious treatments for major depression are available, efficacy is suboptimal and recurrence is common. Effective preventive strategies could reduce disability associated with the disorder, but current options are limited. Cognitive bias modification (CBM) is a novel and safe intervention that attenuates biases associated with depression. This study investigated whether the delivery of a CBM programme designed to attenuate negative cognitive biases over a period of 1 year would decrease the incidence of major depression among adults with subthreshold symptoms of depression. Randomised double-blind controlled trial delivered an active CBM intervention or a control intervention over 52 weeks. Two hundred and two community-dwelling adults who reported subthreshold levels of depression were randomised (100 intervention, 102 control). The primary outcome of interest was the incidence of major depressive episode assessed at 11, 27 and 52 weeks. Secondary outcomes included onset of clinically significant symptoms of depression, change in severity of depression symptoms and change in cognitive biases. Adherence to the interventions was modest though did not differ between conditions. Incidence of major depressive episodes was low. Conditions did not differ in the incidence of major depressive episodes. Likewise, conditions did not differ in the incidence of clinically significant levels of depression, change in the severity of depression symptoms or change in cognitive biases. Active CBM intervention did not decrease the incidence of major depressive episodes as compared to a control intervention. However, adherence to the intervention programme was modest and the programme failed to modify the expected mechanism of action.

Schema therapy for patients with chronic depression: a single case series study. This study tested the effectiveness of schema therapy (ST) for patients with chronic depression. Twelve patients with a diagnosis of chronic depression participated. The treatment protocol consisted of 60 sessions, with the first 55 sessions offered weekly and the last five sessions on a biweekly basis. A single case series A-B-C design, with 6 months follow-up was used. Baseline (A) was a wait period of 8 weeks. Baseline was followed by introduction to ST and bonding to therapist (phase B) with individually tailored length of 12-16 sessions, after which further ST was provided (phase C) up to 60 sessions (included the sessions given as introduction). Patients were assessed with Hamilton Rating Scale for Depression three times during baseline, at the end of phase B, then every 12 weeks until the end of treatment and at 6 months follow-up. Secondary outcome measures were the Hamilton Rating Scale for Anxiety and the Young Schema Questionnaire. At the end of treatment 7 patients (approximately 60%) remitted or satisfactorily responded. The mean HRSD dropped from 21.07 during baseline to 9.40 at post-treatment and 10.75 at follow-up. The effects were large and the gains of treatment were maintained at 6-month follow-up. Only one patient dropped out for reasons not related to treatment. The lack of control group, the small sample and the lack of a multiple baseline case series. This preliminary study supports the use of ST as an effective treatment for chronic depression.

Change in defense mechanisms and coping patterns during the course of 2-year-long psychotherapy and psychoanalysis for recurrent depression: a pilot study of a randomized controlled trial. Very little research has been conducted so far to study the potential mechanisms of change in long-term active psychological treatments of recurrent depression. The present pilot randomized controlled trial aimed to determine the feasibility of studying the change process occurring in patients during the course of 2-year-long dynamic psychotherapy, psychoanalysis, and cognitive therapy, as compared with clinical management. In total, eight outpatients presenting with recurrent depression, two patients per treatment arm, were included. All patients were randomly assigned to one of the four treatment conditions. Defense mechanisms and coping patterns were assessed using validated observer-rated methodology based on transcribed, semistructured follow-along independent dynamic interviews. The results indicated that, whereas some patients in the active treatments changed on the symptomatic levels, some others remained unchanged during the course of their 2-year-long treatment. However, with regard to potential mechanisms of change in these patients, changes in defense mechanisms and coping patterns were revealed to be important processes over time in successful therapies and, to a lesser extent, in less successful treatments. No change was found either on outcome or on the process measure for the control condition, that is, clinical management. These results are discussed along with previous data comparing change in defense mechanisms and coping during the course of treatments.

Is perceived control of depression related to therapy outcome for depression? A longitudinal study. The present study followed a group of patients over a two-year period after they had received a cognitive behavioral psychoeducational intervention targeting patients' ability to cope with depression. The main aims were to examine whether a change in both depressive symptoms and in the perceived control of depression occurred and the relationship between depressive symptoms and perceived control. Using a prospective longitudinal design, a sample of 183 patients was assessed at four time points during a two-year period. The patients showed a large reduction in depressive symptoms over the two-year period after the course ended. During the same time period, perceived controllability of depression increased. A parallel latent growth curve model showed that increased control beliefs were related to reduced depressive symptoms. The decrease in depressive symptoms over time was not dependent on the patients' initial level of depression or initial control of depression, use of medication, duration of previous depressive episodes, alcohol use or sociodemographic variables. Group interventions aimed at increasing coping skills for preventing and mastering of depression may lead to a large and stable reduction in depressive symptoms. A key factor in prevention may be to strengthen patients' perceived ability to cope with the different symptoms of depression.

Effects of intensive short-term dynamic psychotherapy on social cognition in major depression. Background: Social cognition is commonly affected in psychiatric disorders and is a determinant of quality of life. However, there are few studies of treatment.Objective: To investigate the efficacy of intensive short-term dynamic psychotherapy on social cognition in major depression.Method: This study used a parallel group randomized control design to compare pre-test and post-test social cognition scores between depressed participants receiving ISTDP and those allocated to a wait-list control group. Participants were adults (19-40 years of age) who were diagnosed with depression. We recruited 32 individuals, with 16 participants allocated to the ISTDP and control groups, respectively. Both groups were similar in terms of age, sex and educational level.Results: Multivariate analysis of variance (MANOVA) demonstrated that the intervention was effective in terms of the total score of social cognition: the experimental group had a significant increase in the post-test compared to the control group. In addition, the experimental group showed a significant reduction in the negative subjective score compared to the control group as well as an improvement in response to positive neutral and negative states.Conclusion: Depressed patients receiving ISTDP show a significant improvement in social cognition post treatment compared to a wait-list control group.

Identifying change-dropout patterns during an Internet-based intervention for depression by applying the Muthen-Roy model. To date, only few studies have attempted to investigate non-ignorable dropout during Internet-based interventions by applying an NMAR model, which includes missing data indicators in its equations. Here, the Muthen-Roy model was used to investigate change and dropout patterns in a sample of patients with mild-to-moderate depression symptoms (N = 483) who were randomized to a 12-week Internet-based intervention (deprexis, identifier: NCT01636752). Participants completed the PHQ-9 biweekly during the treatment. We identified four change-dropout patterns: Participants showing high impairment, improvement and low dropout probability (C3, N = 134) had the highest rate of reliable change at 6- and 12-month follow-up. A further pattern was characterized by high impairment, deterioration and high dropout probability (C2, N = 32), another by low impairment, improvement and high dropout probability (C1, N = 198). The last pattern was characterized by high impairment, no change and low dropout probability (C4, N = 119). In addition to deterioration, also rapid improvement may lead to dropout as a result of a perceived "good enough" dosage of treatment. This knowledge may strengthen sensitivity for the mechanisms of dropout and help to consider its meaning in efforts to optimize treatment selection.

It can't hurt, right? Adverse effects of psychotherapy in patients with depression. Despite growing awareness of occasional adverse effects of psychological treatments, only a few instruments cover side effects and other unwanted effects of psychotherapy. For the present study, the Positive and Negative Effects of Psychotherapy Scale (PANEPS) was evaluated in a population of individuals with depression who had completed at least one course of face-to-face psychotherapy. A total of 135 individuals with a current or previous depressive episode as verified by a diagnostic interview filled out the online version of the PANEPS, which is designed to capture both positive and adverse events. Factor analysis yielded four dimensions: positive effects, side effects, malpractice, and unethical conduct. Internal consistency of the individual subscales was satisfactory to excellent (Cronbach's α: 0.72 and 0.92). Positive effects were reported by virtually all patients (95.6%). At the same time, approximately half of the sample noted at least one adverse event (52.6%). Among these, side effects (38.5%) and malpractice (26.7%) were significantly more prevalent than unethical conduct (8.1%). As expected, positive effects were negatively correlated with adverse events. Our results challenge the common clinical assumption that some degree of destabilization is necessary for symptom improvement. The survey was conducted anonymously, and the sample underwent diagnostic verification. The results indicate a need for improved treatment guidelines and mechanisms to monitor treatment.

Improved emotion regulation in depression following cognitive remediation: A randomized controlled trial. Executive functions (EFs) play a key role in emotion regulation and, related to this, depression. Cognitive remediation (CR) targeting EFs, such as Goal Management Training (GMT) and computerized cognitive training (CCT), may reduce maladaptive emotion regulation. However, the clinical potential of GMT in the context of depression and emotion regulation remains to be tested. Hence, the primary aim of the present study was to compare effects of GMT with CCT on symptoms of emotion dysregulation. The paper reports the effects of a preregistered randomized controlled trial. Sixty-three participants (18-60yrs) with active or remitted depression and EF complaints were randomized to nine sessions of GMT (n = 35) or CCT (n = 28). All were assessed at baseline, post-intervention, and at 6-month follow-up. The Ruminative Response Scale and the Difficulties in Emotion Regulation Scale were employed to assess emotion regulation. Both groups improved following the intervention on emotion regulation domains after controlling for intention-to-treat, including brooding rumination and on items reflecting non-accepting reactions to distress. Relative to CCT, the GMT-group demonstrated increased clarity of emotional responses in the per protocol analysis. Our findings demonstrate the potential of GMT and CCT in reducing maladaptive emotion regulation in depression.

What the future holds: Machine learning to predict success in psychotherapy. Machine learning (ML) may help to predict successful psychotherapy outcomes and to identify relevant predictors of success. So far, ML applications are scant in psychotherapy research and they are typically based on small samples or focused on specific diagnoses. In this study, we predict successful therapy outcomes with ML in a heterogeneous sample in routine outpatient care. We trained established ML models (decision trees and ensembles of them) with routinely collected clinical baseline information from n = 685 outpatients to predict a successful outcome of cognitive behavioral therapy. Treatment success was defined as clinically significant change (CSC) on the Brief-Symptom-Checklist (reached by 326 patients; 48%). The best performing model (Gradient Boosting Machines) achieved a balanced accuracy of 69% (p < .001) on unseen validation data. Out of 383 variables, we identified the 16 most important predictors, which were still able to predict CSC with 67% balanced accuracy. Our study demonstrates that ML models built on data, which is typically available at the outset of therapy, can predict whether an individual will substantially benefit from the intervention. Some of the predictors were theoretically expected (e.g., level of functioning), but others need further validation (e.g., somatization). From a theoretical and practical perspective, ML is clearly an attractive addition to more established psychotherapy research methodology.

Alleviating distressing intrusive memories in depression: a comparison between computerised cognitive bias modification and cognitive behavioural education. Negative appraisals maintain intrusive memories and intrusion-distress in depression, but treatment is underdeveloped. This study compared the efficacy of computerised bias modification positive appraisal training (CBM) versus a therapist-delivered cognitive behavioural therapy session (CB-Education) that both aimed to target and alter negative appraisals of a negative intrusive autobiographical memory. Dysphoric participants (Mean BDI-II = 27.85; N = 60) completed baseline ratings of a negative intrusive memory, negative appraisals and the Impact of Event Scale, and were randomly allocated either one session of CBM, CB-Education, or a no intervention monitoring control condition (Control). Mood and intrusion symptoms were assessed at one week follow-up. For all groups, there were significant reductions over one week in mood (depression and anxiety), memory intrusiveness and negative appraisals. Groups differed in terms of intrusion-related distress, with the CB-Education group showing greatest reduction, followed by the CBM group. The study provides evidence for the link between maladaptive appraisals of intrusive memories and distress in depressed mood. Further, both a single session of CB-Education and (to a lesser degree) CBM are useful in reducing intrusion-related distress. This study may have been underpowered to detect differences and replication is needed with larger samples.

Changes in interpersonal problems in the psychotherapeutic treatment of depression as measured by the Inventory of Interpersonal Problems: A systematic review and meta-analysis. Interpersonal problems are commonly reported by depressed patients, but the effect of psychotherapeutic treatment on them remains unclear. This paper reviews the effectiveness of psychotherapeutic interventions for depression on interpersonal problems as measured by the Inventory of Interpersonal Problems (IIP). An electronic database search identified articles reporting IIP outcome scores for individual adult psychotherapy for depression. A systematic review and, where possible, meta-analysis was conducted. Twenty-eight studies met inclusion criteria, 10 of which could be included in a meta-analysis investigating changes in the IIP after brief psychotherapy. Reasons for exclusion from the meta-analysis were too few participants with a diagnosis of depression (n=13), IIP means and SDs unobtainable (n=3) and long-term therapy (n=2). A large effect size (g=0.74, 95% CI=0.56-0.93) was found for improvement in IIP scores after brief treatment. Paucity of IIP reporting and treatment type variability mean results are preliminary. Heterogeneity for improvement in IIP after brief psychotherapy was high (I2=75%). Despite being central to theories of depression, interpersonal problems are infrequently included in outcome studies. Brief psychotherapy was associated with moderate to large effect sizes in reduction in interpersonal problems. Of the dimensions underlying interpersonal behaviour, the dominance dimension may be more amenable to change than the affiliation dimension. Yet, high pre-treatment affiliation appeared to be associated with better outcomes than low affiliation, supporting the theory that more affiliative patients may develop a better therapeutic relationship with the therapist and consequently respond more positively than more hostile patients.

Optimizing the ingredients for imagery-based interpretation bias modification for depressed mood: is self-generation more effective than imagination alone? Negative interpretation is thought to be crucial in the development and maintenance of depression. Recently developed cognitive bias modification paradigms, intending to change these biases towards a more optimistic interpretation tendency (CBM-I), seem to offer new promising implications for cognitive therapy innovation. This study aimed to increase our knowledge of the underlying mechanisms of action of imagery-based CBM-I in the context of depressed mood. We therefore compared the efficacy of CBM-I requiring participants to imagine standardized positive resolutions to a novel, more active training version that required participants to generate the positive interpretations themselves. Fifty-four participants were randomly allocated to (1) standardized CBM-I, (2) self-generation CBM-I or (3) a control group. Outcome measures included self-report mood measures and a depression-related interpretation bias measure. Both positive training variants significantly increased the tendency to interpret fresh ambiguous material in an optimistic manner. However, only the standardized imagery CBM-I paradigm positively influenced mood.

Metacognitive Training for Depression: Feasibility, safety and acceptability of two new treatment modules to reduce suicidality. Recent evidence favours psychological interventions explicitly targeting suicidality; however, group treatments on suicidality are rare and are assumed to have unfavourable effects. We developed two modules specifically addressing suicidality that replace two existing modules in the Metacognitive Training for Depression (D-MCT). The aim of the current study was to examine the feasibility, safety, and acceptability of this intervention (D-MCT/S). Forty-eight inpatients with depression received eight sessions of D-MCT/S over 4 weeks in addition to standard treatment. Patients were assessed before the training, 4 and 8 weeks later regarding suicidality (primary outcome: Beck Suicide Scale [BSS]), hopelessness, depression (e.g. Hamilton Depression Rating Scale [HDRS]), dysfunctional attitudes, and self-esteem. Negative effects of the modules and subjective appraisal were assessed. Suicidality, hopelessness, and depression decreased over time. Whereas the effects on the BSS only reached trend level, a large effect was observed when the suicide item of the HDRS was used. Two of the 46 patients (4%) reported a deterioration in their symptoms, but this was not associated with the D-MCT/S. Negative effects of the general training were rather low, and acceptability was high. In general, patients evaluated the two new modules on suicidality similarly to the established modules. However, both modules were assessed as distressing by 39% of the patients. When we addressed suicidality in the D-MCT/S, we did not observe any contagious effects. In fact, the pilot versions of the two modules on suicidality are promising in terms of feasibility, safety, and acceptability. The results will be used to improve current shortcomings. The trial was registered with the German Clinical Trials Register (#DRKS-ID: DRKS00010543) on 23 August 2016.

Introducing a Group Therapy Program (PLAN D) for Young Outpatients with Derealization and Depersonalization: A Pilot Study. Depersonalization and derealization (DD) cause significant distress and are associated with poor role and social functional outcomes. Despite the relatively high prevalence of DD symptoms and the chronic course in those suffering from a DD disorder, there still exists a need for effective interventions. Preliminary evidence indicates that cognitive behavioral therapy (CBT) delivered in an individual setting demonstrates some positive intervention effects for patients with DD regarding their symptom levels. By considering DD-specific treatment needs, a group therapy program was developed as an add-on therapy based on CBT techniques called PLAN D comprising the following elements: psychoeducation, lifestyle interventions, acceptance and mindfulness training, and new patterns of DD-related cognitions. In a pilot study, we present an 8-week group intervention for adolescents and young adults with DD disorder. To our knowledge, no standardized group intervention program for DD exists so far. Thus, this novel intervention represents a promising opportunity to positively influence long-term outcomes and course of DD.

Interpersonal Circumplex Profiles Of Persistent Depression: Goals, Self-Efficacy, Problems, And Effects Of Group Therapy. We assessed severely and persistently depressed patients' interpersonal self-efficacy, problems, and goals, plus changes in interpersonal functioning and depression during 20 weeks of group therapy. Outpatients (32 female, 26 male, mean age = 45 years) completed interpersonal circumplex measures of goals, efficacy, and problems before completing 20 weeks of manualized group therapy, during which we regularly assessed depression and interpersonal style. Compared to normative samples, patients lacked interpersonal agency, including less self-efficacy for expressive/assertive actions; stronger motives to avoid conflict, scorn, and humiliation; and more problems with being too submissive, inhibited, and accommodating. Behavioral Activation and especially Cognitive Behavioral Analysis System of Psychotherapy interventions produced improvements in depression and interpersonal agency, with increases in "agentic and communal" efficacy predicting subsequent decreases in depression. While severely and persistently depressed patients were prone to express maladaptive interpersonal dispositions, over the course of group therapy, they showed increasingly agentic and beneficial patterns of cognitions, motives, and behaviors.

Emotion regulation skills training enhances the efficacy of inpatient cognitive behavioral therapy for major depressive disorder: a randomized controlled trial. Deficits in emotion regulation skills are possible factors maintaining major depressive disorder (MDD). Therefore, the aim of the study was to test whether integrating a systematic emotion regulation training (ERT) enhances the efficacy of routine inpatient cognitive behavioral therapy (CBT) for MDD. In a prospective randomized controlled trial, 432 inpatients meeting criteria for MDD were assigned to receive either routine CBT or CBT enriched with an intense emotion regulation skills training (CBT-ERT). Participants in the CBT-ERT condition demonstrated a significantly greater reduction in depression (response rates - CBT: 75.5%, CBT-ERT: 84.9%; remission rates - CBT: 51.1%, CBT-ERT: 65.1%). Moreover, CBT-ERT participants demonstrated a significantly greater reduction of negative affect, as well as a greater increase of well-being and emotion regulation skills particularly relevant for mental health. Integrating strategies that target emotion regulation skills improves the efficacy of CBT for MDD.

Predictors of treatment attendance in cognitive and dynamic therapies for major depressive disorder delivered in a community mental health setting. Our goal was to evaluate treatment attendance patterns, including both treatment completion and premature termination from treatment, for 2 evidence-based psychotherapies for major depressive disorder (MDD) delivered in a community mental health setting. We explored rates of premature termination across the course of treatment as well as the factors that predicted and moderated premature termination and treatment completion. This investigation included 237 patients with MDD who participated in a noninferiority trial comparing short-term dynamic psychotherapy (DT) to cognitive therapy (CT). Patients in both conditions were offered 16 sessions of treatment and had up to 5 months to complete treatment. All patients completed an extensive self-report battery at treatment baseline as well as measures of the therapeutic alliance and opinions about treatment following Session 2. Premature termination from both treatments was high with 27% of patients discontinuing treatment very early after only an intake session or a single treatment session. Patients in CT were significantly more likely to terminate treatment prematurely, χ²(3) = 14.35, p = .002. Baseline physical health functioning, subthreshold psychotic symptoms, Session 2 ratings of agreement on tasks, and Session 2 ratings of treatment sensibility all independently predicted premature termination of services. Trauma history significantly moderated very early termination of treatment, χ²(3) = 10.26, p = .017, with patients with high trauma histories more likely to complete DT but terminate prematurely from CT. Very early termination from services was higher in CT compared with DT. Including techniques to improve engagement in both therapies and matching patients to treatment based on predictors/moderators may be effective ways to optimize treatment engagement.

The effect of strategies of personal resilience on depression recovery in an Australian cohort: a mixed methods study. Strategies of personal resilience enable successful adaptation in adversity. Among patients experiencing depression symptoms, we explored which personal resilience strategies they find most helpful and tested the hypothesis that use of these strategies improves depression recovery. We used interview and survey data from the Diagnosis, Management and Outcomes of Depression in Primary Care 2005 cohort of patients experiencing depression symptoms in Victoria, Australia. A total of 564 participants answered a computer-assisted telephone interview question at 12 months follow-up, about what they found most helpful for their depression, stress or worries. Depressive disorder and severity were measured at annual follow-up using the Composite International Diagnostic Interview and the Patient Health Questionnaire self-rating questionnaire. Using interview responses, we categorised participants as users or not of strategies of personal resilience, specifically, drawing primarily on expanding their own inner resources or pre-existing relationships: 316 (56%) were categorised as primarily users of personal resilience strategies. Of these, 193 (61%) reported expanding inner resources, 79 (25%) drawing on relationships and 44 (14%) reported both. There was no association between drawing on relationships and depression outcome. There was evidence supporting an association between expanding inner resources and depression outcome: 25 per cent of users having major depressive disorder 1 year later compared to 38 per cent of non-users (adjusted odds ratio: 0.59, confidence interval: 0.36-0.97). This is the first study to show improved outcome for depression for those who identify as most helpful the use of personal resilience strategies. The difference in outcome is important as expanding inner resources includes a range of low intensity, yet commonly available strategies.

Depression and mentalizing: A psychodynamic therapy process study. The present study aimed to explore the relationship between changes in depressive symptoms and the capacity to mentalize over the course of a 3-month inpatient psychodynamic therapy in a sample of 56 patients with depression. Depressive symptoms and mentalizing were assessed weekly during treatment and at 1-year follow-up with the Beck Depression Inventory and the Reflective Functioning Questionnaire (RFQ). Data were analyzed using Latent Growth Curve (LGC) modeling with structured residuals. In the total sample, depressive symptoms improved on average from baseline to the end of treatment, while mentalizing skills did not. However, individual variations were observed in mentalizing skills, with some patients improving while others did not. Within-patient residual changes in mentalizing skills did not predict residual changes in depressive symptoms. Accordingly, the results did not support mentalizing as a mechanism of change at this level. Nonetheless, between-patient effects were found, showing that patients with higher levels of mentalizing at baseline and patients whose mentalizing skills improved over the course of therapy also had greater reductions in depressive symptoms. We suggest that the presence of relatively higher mentalizing skills might be a factor contributing to moderately depressed individuals' ability to benefit from treatment, while relatively poor or absent mentalizing capacity might be part of the dynamics underlying treatment resistance in individuals with severe depression.

Patient interpersonal and cognitive changes and their relation to outcome in interpersonal psychotherapy for depression. Despite interpersonal psychotherapy's (IPT) efficacy for depression, little is known about its change-promoting ingredients. This exploratory study examined candidate change mechanisms by identifying whether patients' interpersonal and cognitive characteristics change during IPT and whether such changes relate to outcomes. Patients were 95 depressed adults receiving manualized IPT. We used multilevel modeling to assess the relation between change in each interpersonal and cognitive domain and outcome. Across all interpersonal and cognitive variables measured, patients showed significant improvement. Unexpectedly, reduced romantic relationship adjustment was related to posttreatment depression reduction (β = 2.028, p = .008, self-rated; β = 1.474, p = .022, clinician-rated). For the other measured domains, change was not significantly associated with outcome (though changes in some interpersonal variables evidenced a trend-level relation to outcome). Possible reciprocal influences among IPT, depression, and romantic relationship functioning are discussed, as are implications for future research.

Using Artificial Intelligence to Predict Change in Depression and Anxiety Symptoms in a Digital Intervention: Evidence from a Transdiagnostic Randomized Controlled Trial. While digital psychiatric interventions reduce treatment barriers, not all persons benefit from this type of treatment. Research is needed to preemptively identify who is likely to benefit from these digital treatments in order to redirect those people to a higher level of care. The current manuscript used an ensemble of machine learning methods to predict changes in major depressive and generalized anxiety disorder symptoms from pre to 9-month follow-up in a randomized controlled trial of a transdiagnostic digital intervention based on participants' (N=632) pre-treatment data. The results suggested that baseline characteristics could accurately predict changes in depressive symptoms in both treatment groups (r=0.482, 95% CI[0.394, 0.561]; r=0.477, 95% CI[0.385, 0.560]) and anxiety symptoms in both treatment groups (r=0.569, 95% CI[0.491, 0.638]; r=0.548, 95% CI[0.464, 0.622]). These results suggest that machine learning models are capable of preemptively predicting a person's responsiveness to digital treatments, which would enable personalized decision-making about which persons should be directed towards standalone digital interventions or towards blended stepped-care.

Depression and psychodynamic psychotherapy. Depression is a complex condition, and its classical biological/psychosocial distinction is fading. Current guidelines are increasingly advocating psychotherapy as a treatment option. Psychodynamic psychotherapy models encompass a heterogeneous group of interventions derived from early psychoanalytic conceptualizations. Growing literature is raising awareness in the scientific community about the importance of these treatment options, as well as their favorable impact on post-treatment outcomes and relapse prevention. Considering the shifting paradigm regarding treatment of depressive disorder, the authors aim to provide a brief overview of the definition and theoretical basis of psychodynamic psychotherapy, as well as evaluate current evidence for its effectiveness.

How and when immersion and distancing are useful in emotion focused therapy for depression. Objective: The potential benefit or harm of immersion (egocentric perspective) and distancing (observer perspective) on negative experiences are unclear and have not been empirically investigated in therapy. This is a first exploratory study aimed to analyze and compare the perspectives adopted on reflection (immersion and distancing) of negative experiences across therapy and the relationship between them and depressive symptoms in contrasting therapeutic outcomes of emotion-focused therapy (EFT). Method: Three good-outcomes cases and three poor-outcomes cases of EFT, diagnosed with mild to moderate depression at the beginning of therapy, were randomly selected. Immersion and distancing on negative experiences were analyzed using the measure of immersed and distanced speech. The depressive symptoms were assessed by the Beck Depression Inventory-II. Results: Significant differences across sessions were only found in the good-outcome cases which showed a significant decrease of immersion and an increase of distancing, and this evolution pattern was found related to the reduction of symptoms. Moreover, at the beginning of therapy, distancing was higher in the poor-outcome cases rather than in the good-outcome cases. Conclusion: The progressive and significant evolution from higher immersion at the initial phase to higher distancing in the final phase may be helpful in EFT for depression.

Latent change score modeling as a method for analyzing the antidepressant effect of a psychosocial intervention in Alzheimer's disease. Developing and evaluating interventions for patients with age-associated disorders is a rising field in psychotherapy research. Its methodological challenges include the high between-subject variability and the wealth of influencing factors associated with longer lifetime. Latent change score modeling (LCSM), a technique based on structural equation modeling, may be well suited to analyzing longitudinal data sets obtained in clinical trials. Here, we used LCSM to evaluate the antidepressant effect of a combined cognitive behavioral/cognitive rehabilitation (CB/CR) intervention in Alzheimer's disease (AD). LCSM was applied to predict the change in depressive symptoms from baseline as an outcome of the CORDIAL study, a randomized controlled trial involving 201 patients with mild AD. The participants underwent either the CORDIAL CB/CR program or standard treatment. Using LCSM, the model best predicting changes in Geriatric Depression Scale scores was determined based on this data set. The best fit was achieved by a model predicting a decline in depressive symptoms between before and after testing. Assignment to the intervention group as well as female gender revealed significant effects in model fit indices, which remained stable at 6- and 12-month follow-up examinations. The pre-post effect was pronounced for patients with clinically relevant depressive symptoms at baseline. LCSM confirmed the antidepressant effect of the CORDIAL therapy program, which was limited to women. The effect was pronounced in patients with clinically relevant depressive symptoms at baseline. Methodologically, LCSM appears well suited to analyzing longitudinal data from clinical trials in aged populations, by accounting for the high between-subject variability and providing information on the differential indication of the probed intervention.

When less could be more: Investigating the effects of a brief internet-based imagery cognitive bias modification intervention in depression. Depression is a highly prevalent condition worldwide, yet multiple barriers to treatments means that the development of low intensive and easily accessible psychological interventions is crucially needed. The current study sought to investigate the efficacy of a brief, self-administered imagery cognitive bias modification (imagery CBM) procedure delivered online to a sample of 101 individuals with depressive symptoms. Compared to a closely matched control condition or a waitlist condition, imagery CBM led to greater improvements in depressive symptoms (d = 0.86, 95% CI = [0.33, 1.3] and d = 1.17, 95% CI = [0.62, 1.65]) interpretation bias and anhedonia. Despite the limitation to a two week follow-up, the study findings highlight the potential of imagery CBM as a brief, easily accessible intervention for depression that can be delivered remotely in peoples' home.

Assessing in-session rumination and its effects on CBT for depression. The study evaluated if rumination of patients during therapy (i.e., in-session rumination) relates to whether or not they do less well in CBT treatment. We developed a reliably assessed in-session rumination observational measure and evaluated its relationship to depression over the course of CBT. Rated sessions came from 63 treatment-naïve patients with major depressive disorder who participated in CBT in the PReDICT study (Dunlop et al., 2017). In-session rumination was operationalized as repetitive, negative, and passive talking about depressive topics. Trained undergraduates rated the intensity and duration of in-session rumination occurring during 57 initial therapy sessions (i.e., session one) and 45 sessions in the middle of treatment (i.e., session eight). The observational ratings were sufficiently reliable (all ICCs > 0.69). Mixed model results indicated that greater intensity of in-session rumination during the initial treatment session predicted higher levels of subsequent clinician-rated depressive symptoms (p < .023). Regression results indicated that greater intensity and duration of in-session rumination at session 8 significantly predicted higher clinician-rated symptoms at end of treatment (p's < 0.02). In-session rumination intensity and duration were not, however, related to subsequent self-reported depressive symptoms. The results support efforts to identify which patients might benefit from rumination-specific interventions.

An investigation of extreme responding as a mediator of cognitive therapy for depression. Although the efficacy of Cognitive Therapy (CT) for depression is well documented, questions remain about the conditions under which CT is maximally effective, and the mechanisms by which CT is efficacious. This study examined the role of extreme responding (ER) as a mediator and predictor of relapse, as well as a predictor of acute treatment outcome. To test mediation, ER of participants in CT was compared to ER of participants receiving Behavioral Activation (BA). Results indicated that ER was not a mediator of relapse in either condition. Both CT and BA showed reductions in depression severity, however neither group showed significant changes in ER over the course of treatment. Finally, ER did not predict or moderate acute treatment outcome. The implications of these results, strengths and limitations of the current study, and future research directions are discussed.

Cognitive and Metacognitive Mechanisms of Change in Metacognitive Training for Depression. Metacognitive Training for Depression (D-MCT), a low-threshold group intervention, has been shown to improve depressive symptoms. It aims at the reduction of depression by changing dysfunctional cognitive as well as metacognitive beliefs. The purpose of the present study was to investigate whether the mechanisms of change in D-MCT are cognitive (and thus primarily concern the content of cognition) or metacognitive in nature. Eighty-four outpatients with depression were included in a randomized controlled trial comparing D-MCT to an active control intervention. Level of depression, dysfunctional cognitive beliefs (DAS), and metacognitive beliefs (MCQ subscales: Positive Beliefs, Negative Beliefs, Need for Control) were assessed before (t0) and after treatment (t1). Severity of depression was also assessed 6 months later (t2). Linear regression analyses were used to determine whether change in depression from t0 to t2 was mediated by change in cognitive vs. metacognitive beliefs from t0 to t1. D-MCT's effect on change in depression was mediated by a decrease in dysfunctional metacognitive beliefs, particularly 'need for control'. Our findings underline that one of the key mechanisms of improvement in D-MCT is the change in metacognitive beliefs. The current study provides further support for the importance of metacognition in the treatment of depression.

Efficacy of an internet and app-based gratitude intervention in reducing repetitive negative thinking and mechanisms of change in the intervention's effect on anxiety and depression: Results from a randomized controlled trial. Repetitive negative thinking (RNT) has been identified as a transdiagnostic process that is involved in various forms of psychopathology, including anxiety and depression. This randomized controlled trial compared a 5-week internet and app-based gratitude intervention (intervention group; IG) with adherence-focused guidance against a wait list control group (WLG) in reducing RNT in a sample with elevated RNT. A total of 260 individuals were randomized to either the IG or the WLG. Data were collected at baseline (T1), within one week post intervention (T2), and at three (3-MFU) and six-months of follow-up (6-MFU; for IG only). The primary outcome was RNT. Secondary outcomes included other mental health outcomes and resilience factors. Participants of the IG reported significantly less RNT at T2 (d = 0.61) and 3-MFU (d = 0.75) as compared to WLG. Improvements were sustained until 6-MFU. Significant, small to moderate effect sizes were identified for most secondary outcomes at T2 and 3-MFU. Furthermore, results of mediation analyses revealed that the gratitude intervention exerts its effect on anxiety and depression by reducing the risk factor of RNT, while the mediating role of resilience was less clear. The gratitude intervention investigated in this study was found to be effective in reducing RNT. Gratitude interventions might affect mental health by two parallel pathways: increasing resources and reducing risk factors. EB 201701-03-Lehr. DRKS00011862.

Metacognitive Training for Depression (D-MCT) reduces false memories in depression. A randomized controlled trial. Metacognitive Training for Depression (D-MCT) is a highly standardized group program targeted at depression-related ("Beckian") emotional as well as cognitive biases, including mood-congruent and false memory. While prior results are promising with respect to psychopathological outcomes (depression), it is unclear whether D-MCT also meets its goal of improving cognitive biases, such as false memories. In the framework of a randomized controlled trial (registered trial, DRKS00007907), we investigated whether D-MCT is superior to an active control condition (health training, HT) in reducing the susceptibility of depressed patients for false memories. False memories were examined using parallel versions of a visual variant of the Deese-Roediger McDermott paradigm. Both groups committed less false memories at post assessment after 4 weeks compared to baseline. Relative to HT, D-MCT led to a significant decrease in high-confident false memories over time. The study presents first evidence that D-MCT decreases the susceptibility of depressed patients for false memories, particularly for errors made with high confidence that are presumably the most "toxic" in terms of mood-congruent memory distortions.

Sequential multiple assignment randomized trial (SMART) with adaptive randomization for quality improvement in depression treatment program. Implementation study is an important tool for deploying state-of-the-art treatments from clinical efficacy studies into a treatment program, with the dual goals of learning about effectiveness of the treatments and improving the quality of care for patients enrolled into the program. In this article, we deal with the design of a treatment program of dynamic treatment regimens (DTRs) for patients with depression post-acute coronary syndrome. We introduce a novel adaptive randomization scheme for a sequential multiple assignment randomized trial of DTRs. Our approach adapts the randomization probabilities to favor treatment sequences having comparatively superior Q-functions used in Q-learning. The proposed approach addresses three main concerns of an implementation study: it allows incorporation of historical data or opinions, it includes randomization for learning purposes, and it aims to improve care via adaptation throughout the program. We demonstrate how to apply our method to design a depression treatment program using data from a previous study. By simulation, we illustrate that the inputs from historical data are important for the program performance measured by the expected outcomes of the enrollees, but also show that the adaptive randomization scheme is able to compensate poorly specified historical inputs by improving patient outcomes within a reasonable horizon. The simulation results also confirm that the proposed design allows efficient learning of the treatments by alleviating the curse of dimensionality.

Internet-delivered cognitive control training as a preventive intervention for remitted depressed patients: Evidence from a double-blind randomized controlled trial study. Cognitive control impairments may place remitted depressed (RMD) patients at increased risk for developing future depressive symptomatology by disrupting emotion regulation processes. Research has shown that directly targeting cognitive control has beneficial effects on high trait ruminators and clinically depressed patients. The current study tested whether internet-delivered cognitive control training (CCT) can be used as an intervention to increase resilience to depression in RMD patients. Effects of CCT were assessed using a double-blind randomized controlled design. RMD patients performed 10 sessions of a working memory-based CCT (N = 34) or a low cognitive load training (N = 34; active control condition) over a period of 14 days. Assessments took place prior to training, immediately following 2 weeks of training, and at 3 months follow-up. Brooding and depressive symptomatology were selected as primary outcome measures, alternative indicators for emotion regulation and residual symptomatology were selected as secondary outcome measures, along with indicators of functioning. Compared to an active control condition, CCT demonstrated beneficial effects on a cognitive transfer task, brooding, depressive symptomatology, residual complaints, self-reported use of general maladaptive emotion regulation strategies, and resilience after controlling for intention to treat. Furthermore, completers of the CCT reported a reduction in experienced disability and cognitive complaints. However, no beneficial effects were found for self-reported use of adaptive emotion regulation strategies. These findings demonstrate the effectiveness of CCT as an intervention to reduce cognitive vulnerability, residual symptomatology, and foster resilience following recovery from depression. CCT thus holds potential as a preventive intervention for RMD patients. (PsycINFO Database Record

Cognitive training for modifying interpretation and attention bias in depression: Relevance to mood improvement and implications for cognitive intervention in depression. Depressed individuals interpret ambiguous information more negatively and this has been suggested a central component in cognitive models of depression. In this study we investigated the effectiveness of the interpretation modification training on modifying interpretation bias in depression and its association with symptoms reduction. In a double-blind, randomized controlled design, twenty-two depressed individuals (mean age=19.86, SD=1.16) were randomly assigned to the experimental and control groups. They completed 10 sessions of cognitive training with the Ambiguous Hallmark Program (AHP) over 5 weeks. Participants' interpretation bias and their depressive scores were assessed and compared before and after the intervention. Results showed that the AHP significantly decreased negative interpretation in the experimental group. Additionally, a significant decrease in the depressive scores was also observed in the intervention group compared to the control group. We also observed the transfer of learning from the AHP training to another interpretation bias task. The AHP can significantly modify negative interpretations and symptoms in depression providing preliminary supporting evidence for its clinical application especially in mild-to-moderate depression. Improved cognitive control over emotional information and unbiased attention to them could explain effects of the Interpretation modification paradigm. Further studies need to examine the efficacy of the AHP as a potential cognitive intervention in depression.

Social problem solving and depressive symptoms over time: a randomized clinical trial of cognitive-behavioral analysis system of psychotherapy, brief supportive psychotherapy, and pharmacotherapy. Depression is associated with poor social problem solving, and psychotherapies that focus on problem-solving skills are efficacious in treating depression. We examined the associations between treatment, social problem solving, and depression in a randomized clinical trial testing the efficacy of psychotherapy augmentation for chronically depressed patients who failed to fully respond to an initial trial of pharmacotherapy (Kocsis et al., 2009). Participants with chronic depression (n = 491) received cognitive-behavioral analysis system of psychotherapy (CBASP; McCullough, 2000), which emphasizes interpersonal problem solving, plus medication; brief supportive psychotherapy (BSP) plus medication; or medication alone for 12 weeks. CBASP plus pharmacotherapy was associated with significantly greater improvement in social problem solving than BSP plus pharmacotherapy, and a trend for greater improvement in problem solving than pharmacotherapy alone. In addition, change in social problem solving predicted subsequent change in depressive symptoms over time. However, the magnitude of the associations between changes in social problem solving and subsequent depressive symptoms did not differ across treatment conditions. It does not appear that improved social problem solving is a mechanism that uniquely distinguishes CBASP from other treatment approaches.

Rumination as a predictor of relapse in mindfulness-based cognitive therapy for depression. In mindfulness-based cognitive therapy (MBCT), it is proposed that training in mindfulness should reduce the tendency of formerly depressed patients to enter into ruminative thinking, thus reducing their risk of depressive relapse. However, data showing that rumination is associated with depressive relapse are lacking. In an uncontrolled study with 24 formerly depressed patients, rumination was assessed with the Ruminative Response Scale. To assess the occurrence of relapse or recurrence, the Structured Clinical Interview for DSM-IV was administered 12 months after the end of the MBCT. Rumination significantly decreased during the MBCT course. Post-treatment levels of rumination predicted the risk of relapse of major depressive disorder in the 12-month follow-up period even after controlling for numbers of previous episodes and residual depressive symptoms. The results provide preliminary evidence that rumination is important in the process of depressive relapse.

Therapeutic alliance in face-to-face and telephone-administered cognitive behavioral therapy. Telephone-administered therapies have emerged as an alternative method of delivery for the treatment of depression, yet concerns persist that the use of the telephone may have a deleterious effect on therapeutic alliance. The purpose of this study was to compare therapeutic alliance in clients receiving cognitive behavioral therapy (CBT) for depression by telephone (T-CBT) or face-to-face (FtF-CBT). We randomized 325 participants to receive 18 sessions of T-CBT or FtF-CBT. The Working Alliance Inventory (WAI) was administered at Weeks 4 and 14. Depression was measured during treatment and over 1 year posttreatment follow-up using the Hamilton Rating Scale for Depression and Patient Health Questionnaire-9. There were no significant differences in client or therapist WAI between T-CBT or FtF-CBT (Cohen's f² ranged from 0 to .013, all ps > .05). All WAI scores predicted depression end of treatment outcomes (Cohen's f² ranged from .009 to .06, all ps < .02). The relationship between the WAI and depression outcomes did not vary by treatment group (Cohen's f² ranged from 0 to .004, ps > .07). The WAI did not significantly predict depression during posttreatment follow-up (all ps > .12). Results from this analysis do not support the hypothesis that the use of the telephone to provide CBT reduces therapeutic alliance relative to FtF-CBT.

The Effects of Computerized Cognitive Control Training on Community Adults with Depressed Mood. Depression is frequently characterized by patterns of inflexible, maladaptive, and ruminative thinking styles, which are thought to result from a combination of decreased attentional control, decreased executive functioning, and increased negative affect. Cognitive Control Training (CCT) uses computer-based behavioral exercises with the aim of strengthening cognitive and emotional functions. A previous study found that severely depressed participants who received CCT exhibited reduced negative affect and rumination as well as improved concentration. The present study aimed to extend this line of research by employing a more stringent control group and testing the efficacy of three sessions of CCT over a 2-week period in a community population with depressed mood. Forty-eight participants with high Beck Depression Inventory (BDI-II) scores were randomized to CCT or a comparison condition (Peripheral Vision Training; PVT). Significant large effect sizes favoring CCT over PVT were found on the BDI-II (d = 0.73, p < .05) indicating CCT was effective in reducing negative mood. Additionally, correlations showed significant relationships between CCT performance (indicating ability to focus attention on CCT) and state affect ratings. Our results suggest that CCT is effective in altering depressed mood, although it may be specific to select mood dimensions.

Does cognitive behavioral therapy for depression target positive affect? Examining affect and cognitive change session-to-session. Researchers have been interested in the role of negative affect (NA) and positive affect (PA) in cognitive behavioral therapy (CBT) for depression. We examined cognitive change (CC) and these two affect variables across the course of CBT. Patients (N = 125; M age = 31.7, SD = 13.35; 60% female; 83% Caucasian) participated in 16 weeks of CBT for depression. They completed the Beck Depression Inventory-II (BDI-II) and the Immediate Cognitive Change Scale at each session and a measure of affect before and after each session. NA decreased (rate of change p < .001, d = -1.08) and PA increased (p < .001, d = 0.53) during treatment. CC predicted next-session PA, 0.06, 95% CI [0.01, 0.11], and NA, -0.09, 95% CI [-0.14, -0.04], and was concurrently associated with change in PA, 0.36, 95% CI [0.30, 0.42], and NA, -0.32, 95% CI [-0.42, -0.26], over the course of a session. Presession PA, 0.22, 95% CI [0.17, 0.26], and NA, -0.13, 95% CI [-0.17, -0.08], predicted postsession CC, while pre to postsession change in PA, -0.05, 95% CI [-0.09, -0.002], and NA, 0.06, 95% CI [0.01, 0.11], predicted change in depressive symptoms. Although NA and PA both change in CBT, the changes in PA are more modest. Both NA and PA predict symptom change, consistent with the possibility that increasing PA may be beneficial. CC and affect change are reciprocally related, suggesting that CC may contribute to affect change, while affect may also facilitate CC. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Social skills training for depression and comparative efficacy research: a 30-year retrospective. By the late 1970s it was clear that cognitive and behavioral therapies were promising alternatives to antidepressant medications for treatment of depressed outpatients. One such model of therapy, Social Skills Training, was developed by Michel Hersen and his colleagues specifically for treatment of depressed women. Professor Hersen and his colleagues obtained funding from the National Institute of Mental Health to conduct the first well-controlled randomized trial of this intervention, contrasting Social Skills Training, in combination with either placebo or active amitriptyline, against two active standards: amitriptyline alone and time-limited, psychodynamic psychotherapy in combination with placebo. The results of this study suggested that Social Skills Training (plus placebo) was at least as effective as amitriptyline alone or psychodynamic psychotherapy (plus placebo), with superior mode-specific effects on measures of social skill. The current narrative, which provides an autobiographical perspective of four critical years (1980-1984) in the early career of the author that were intertwined with the conduct and completion of this clinical trial, is an homage to Professor Hersen's talents as a supervisor, researcher, and mentor.

The impact of personality disorder pathology on the effectiveness of Cognitive Therapy and Interpersonal Psychotherapy for Major Depressive Disorder. Despite extensive research, there is no consensus how Personality Disorders (PD) and PD features affect outcome for Major Depressive Disorder (MDD). The present study evaluated the effects of PD (features) on treatment continuation and effectiveness in Cognitive Therapy (CT) and Interpersonal Psychotherapy (IPT) for MDD. Depressed outpatients were randomized to CT (n=72) and IPT (n=74). Primary outcome was depression severity measured repeatedly with the Beck Depression Inventory-II (BDI-II) at baseline, three months, at the start of each therapy session, at post-treatment and monthly during five months follow-up. Comorbid PD and PD features did not affect dropout. Multilevel and Cox regression models indicated no negative effect of PD on BDI-II change and remission rates during treatment and follow-up, irrespective of the treatment received. For both therapies, higher dependent PD features predicted overall lower BDI-II scores during treatment, however this effect did not sustain through follow-up. Cluster A PD features moderated treatment outcome during treatment and follow-up: individuals with high cluster A PD features had greater BDI-II reductions over time in CT as compared to IPT. Not all therapists and participants were blind to the assessment of PD (features), and assessments were performed by one rater. Further research must investigate the state and trait dependent changes of PD and MDD over time. We found no negative impact of PD on the effectiveness and treatment retention of CT and IPT for MDD during treatment and follow-up. If replicated, cluster A PD features can be used to optimize treatment selection.

Predictors of Symptom Outcome in Interpretation Bias Modification for Dysphoria. Interpretation Bias Modification (IBM) interventions have been effective in reducing negative interpretation biases theorized to underlie depressive psychopathology. Although these programs have been highlighted as potential short-term interventions for depression, mixed evidence has been found for their effects on depressive symptoms. There is a need to examine attitudes towards training as well as individual difference factors that may impact symptom outcomes for IBM depression interventions. Seventy-two dysphoric young adults were randomly assigned to receive either an IBM targeting negative interpretation bias in personal evaluations or interpersonal situations or a healthy video control (HVC) condition. Compared to those who received HVC, participants in the IBM condition reported lower negative interpretation bias at posttreatment. No differences between conditions were found for symptom outcomes. Greater perceived treatment credibility and expectancy were associated with better treatment outcomes for both the IBM and HVC groups. Within the IBM group, a greater tendency toward assimilation with treatment scenarios was significantly associated with better treatment outcomes for both depressive and anger symptoms. This effect was unique from treatment credibility and expectancy. Pretreatment psychological reactance did not predict treatment response for either condition. Implications and future research directions are discussed.

Comparison and change of defense mechanisms over the course of psychotherapy in patients with depression or anxiety disorder: Evidence from a randomized controlled trial. Defense mechanisms play an important role in the development and maintenance of both health and psychopathology. Research is still in the early stages of investigating the specific relationships among diagnostic groups and defense mechanisms along with their response to different treatment types. For the present study a total of 47 outpatients diagnosed with depression or anxiety disorders were randomized to receive 25±3 sessions of cognitive-behavioral therapy with integrated elements of either emotion-focused therapy (CBT + EFT) or treatment components based on self-regulation theory (CBT + SR). An observer-rated method, the Defense Mechanism Rating Scale (DMRS) was used to code transcripts of the 1st, 8th, 16th and 24th session to assess change in defensive functioning. Over the course of therapy, overall defensive functioning (ODF) as well as adaptive defenses increased significantly, whereas maladaptive and neurotic defenses did not change. At the beginning of treatment, the proportion of adaptive defenses and ODF was significantly higher in patients diagnosed with anxiety disorders than in patients with depressive disorders. However, depressed patients exhibited greater improvement in their defensive functioning over the course of therapy. Results support the view of defense mechanisms as a useful transdiagnostic and transtheoretical concept and supports the notion that change of defense mechanisms may be a relevant mechanism of change in psychotherapy.

Interpersonal clarification effects in Cognitive-Behavioral Therapy for depression and how they are moderated by the therapeutic alliance. Although a wide body of research links depression to interpersonal deficits, Cognitive-Behavioral Therapy (CBT), considered the gold standard in the treatment of this condition, has not been developed to specifically address interpersonal difficulties. However, cognitive changes on a relational level occurring during CBT might play an important role in the treatment of depression. Interpersonal clarification refers to the process of better understanding the nature of one's interpersonal patterns during therapy. The aim of this study is to analyze the effects of interpersonal clarification in CBT and how they are moderated by the therapeutic alliance. A sample of 621 patients diagnosed with depression were treated with CBT by 126 therapists in a university outpatient clinic. Patients completed measures of interpersonal problems and depression severity at baseline, measures of symptomatic evolution before each session and process measures (assessing interpersonal clarification and alliance) after each session. Multilevel models separating between-patient (BP) and within-patient (WP) effects of interpersonal clarification, and including BP and WP alliance effects as covariates and moderators of the interpersonal clarification effects were conducted. Analyses showed both significant BP and WP effects interpersonal clarification, even when adjusting for alliance effects. Furthermore, significant interactive effects were found between outcome of WP interpersonal clarification with both BP alliance and WP alliance. Interpersonal clarification was measured with one single-item and adherence to CBT was not explicitly measured. The results present preliminary evidence for considering interpersonal clarification a meaningful change process in CBT for depression, especially in the context of a stronger therapeutic alliance.

The Current Research Landscape on the Artificial Intelligence Application in the Management of Depressive Disorders: A Bibliometric Analysis. Artificial intelligence (AI)-based techniques have been widely applied in depression research and treatment. Nonetheless, there is currently no systematic review or bibliometric analysis in the medical literature about the applications of AI in depression. We performed a bibliometric analysis of the current research landscape, which objectively evaluates the productivity of global researchers or institutions in this field, along with exploratory factor analysis (EFA) and latent dirichlet allocation (LDA). From 2010 onwards, the total number of papers and citations on using AI to manage depressive disorder have risen considerably. In terms of global AI research network, researchers from the United States were the major contributors to this field. Exploratory factor analysis showed that the most well-studied application of AI was the utilization of machine learning to identify clinical characteristics in depression, which accounted for more than 60% of all publications. Latent dirichlet allocation identified specific research themes, which include diagnosis accuracy, structural imaging techniques, gene testing, drug development, pattern recognition, and electroencephalography (EEG)-based diagnosis. Although the rapid development and widespread use of AI provide various benefits for both health providers and patients, interventions to enhance privacy and confidentiality issues are still limited and require further research.

Interpersonal problems as predictors of therapeutic alliance and symptom improvement in cognitive therapy for depression. The degree to which interpersonal problems of depressed patients improve over the course of cognitive therapy (CT) and relate to the quality of the therapeutic alliance and to symptom improvement, remains unclear. We analyzed data of adult outpatients (N=523) with major depressive disorder participating in a clinical trial to determine the factor structure of the Inventory of Interpersonal Problems-Circumplex (IIP-C) and to relate the observed factor scores to the quality of the therapeutic alliance and symptom improvement over the course of CT. Patients received 16-20 sessions protocol (50-60 min each) of individual CT according to the treatment manual by Beck et al. (1979). We found a three-factor structure (interpersonal distress, agency, and communion) of interpersonal problems. Interpersonal distress decreased (d=.90), but interpersonal style did not change substantively during CT (communion d=.03; agency d=.14). High initial agency scores related negatively to the therapeutic alliance (β=-.12), whereas high initial communion scores related positively to the therapeutic alliance (β=.15). Elevated pre-treatment interpersonal distress scores were related to both weaker therapeutic alliances (β=.13) and higher symptom levels throughout treatment (β=.10). All patients in this study had recurrent MDD and it is therefore uncertain whether the results would generalize to patients with other psychiatric disorders. This study supports the use of the IIP-C as a comprehensive measure of patients' interpersonal style and interpersonal distress. The IIP-C measured before CT showed some predictive validity with respect to therapeutic alliance measured at the midpoint and therapy outcome. The clinical importance of these findings is discussed.

Can integrating the Memory Support Intervention into cognitive therapy improve depression outcome? A randomized controlled trial. We investigated if improving a patient's memory for the content of their treatment, via the Memory Support Intervention, improves illness course and functional outcomes. The platform for investigating this question was major depressive disorder (MDD) and cognitive therapy (CT). Adults diagnosed with MDD (N = 178) were randomly allocated to CT + Memory Support (n = 91) or CT-as-usual (n = 87). Both treatments were comprised of 20-26, 50-min sessions over 16 weeks. Blind assessments were conducted before and immediately following treatment (post-treatment) and 6 months later (6FU). Patient memory for treatment, assessed with a free recall task, was higher in CT + Memory Support for past session recall at post-treatment. Both treatment arms were associated with reductions in depressive symptoms and functional impairment except: CT + Memory Support exhibited lower depression severity at 6FU (b = -3.09, p = 0.050, d = -0.27), and greater reduction in unhealthy days from baseline to 6FU (b = -4.21, p = 0.010, d = -1.07), compared to CT-as-usual. While differences in illness course and functional outcomes between the two treatment arms were limited, it is possible that future analyses of the type of memory supports and longer follow-up may yield more encouraging outcomes.

Rumination-focused cognitive-behavioural therapy for residual depression: phase II randomised controlled trial. About 20% of major depressive episodes become chronic and medication-refractory and also appear to be less responsive to standard cognitive-behavioural therapy (CBT). To test whether CBT developed from behavioural activation principles that explicitly and exclusively targets depressive rumination enhances treatment as usual (TAU) in reducing residual depression. Forty-two consecutively recruited participants meeting criteria for medication-refractory residual depression were randomly allocated to TAU v. TAU plus up to 12 sessions of individual rumination-focused CBT. The trial has been registered (ISRCTN22782150). Adding rumination-focused CBT to TAU significantly improved residual symptoms and remission rates. Treatment effects were mediated by change in rumination. This is the first randomised controlled trial providing evidence of benefits of rumination-focused CBT in persistent depression. Although suggesting the internal validity of rumination-focused CBT for residual depression, the trial lacked an attentional control group so cannot test whether the effects were as a result of the specific content of rumination-focused CBT v. non-specific therapy effects.

What Do People Really Think of Me? Evaluating Bias in Interpersonal Predictions Over the Course of Cognitive-Behavioral Therapy of Depression. Cognitive behavioral therapy (CBT) of depression is hypothesized to achieve its effects by correcting negative biases. However, little research has tested how biases change over the course of CBT. We focus on biases in interpersonal judgments and examine whether changes in biases occur in CBT and are associated with symptom improvements. A sample of 126 adults (60% women, mean age 31.7, 83% White) participated in CBT of depression. Observers provided ratings of patients participating in two interpersonal tasks on three occasions. Patients were asked to predict observers' ratings. In a thin slice (TS) task, observers evaluated how patients came across in a brief segment in which patients talked about themselves. In a Standard Interaction Task (SIT), observers rated the social skills patients displayed in challenging role plays. The difference between patient predictions and observer ratings provided measures of bias in these interpersonal judgments. TS and SIT bias became significantly less pessimistic and more realistic over the course of CBT. Improvements in TS bias were associated with a faster reduction in symptoms, whereas there was a non-significant trend for improvement in SIT bias being associated with faster symptom reduction. Consistent with the CBT model, negative interpersonal biases became more realistic throughout a course of CBT for depression and at least some of the changes in bias were related to therapeutic outcomes. We encourage future researchers to continue examining for whom and under which conditions correcting such biases produces the greatest benefits.

Predictors of treatment dropout in self-guided web-based interventions for depression: an 'individual patient data' meta-analysis. It is well known that web-based interventions can be effective treatments for depression. However, dropout rates in web-based interventions are typically high, especially in self-guided web-based interventions. Rigorous empirical evidence regarding factors influencing dropout in self-guided web-based interventions is lacking due to small study sample sizes. In this paper we examined predictors of dropout in an individual patient data meta-analysis to gain a better understanding of who may benefit from these interventions. A comprehensive literature search for all randomized controlled trials (RCTs) of psychotherapy for adults with depression from 2006 to January 2013 was conducted. Next, we approached authors to collect the primary data of the selected studies. Predictors of dropout, such as socio-demographic, clinical, and intervention characteristics were examined. Data from 2705 participants across ten RCTs of self-guided web-based interventions for depression were analysed. The multivariate analysis indicated that male gender [relative risk (RR) 1.08], lower educational level (primary education, RR 1.26) and co-morbid anxiety symptoms (RR 1.18) significantly increased the risk of dropping out, while for every additional 4 years of age, the risk of dropping out significantly decreased (RR 0.94). Dropout can be predicted by several variables and is not randomly distributed. This knowledge may inform tailoring of online self-help interventions to prevent dropout in identified groups at risk.

Modification of Hostile Interpretation Bias in Depression: A Randomized Controlled Trial. Interpretation Bias Modification (IBM) is gaining attention in the literature as an intervention that alters cognitive biases and reduces associated symptoms. Forty, primarily college-aged, non-treatment-seeking adults with major depressive disorder (MDD) were randomly assigned to receive either IBM targeting hostile interpretation bias (IBM-H) or a healthy video control (HVC) condition. Compared to those in HVC, participants in IBM-H reported more benign interpretations and fewer hostile interpretations at posttreatment. No difference in depressive interpretation bias was found between groups at posttreatment. IBM-H led to improved anger control at posttreatment and follow-up compared to HVC, though no effects of condition were found on trait anger or depressive symptoms. The IBM-H group perceived their treatment as less credible than the HVC group. For individuals with high expectancy of treatment success, IBM-H led to lower posttreatment depressive symptoms compared to HVC, while findings trended in the opposite direction for those with low expectancy of success. Overall, these preliminary findings point to boundary conditions for the efficacy of IBM protocols for anger and depression and potential improvements to be made to future IBM protocols.

Assessment of Automatic Thoughts in Patients with Depressive Illness at a Tertiary Hospital in Nepal. Cognitive functions have significant influence on psycho-social and general wellbeing. The quality, content and processing of negative thoughts initiate depressive symptoms; i.e. low mood, decreased self-worth and diminished interest in pleasurable activities. The study assessed the automatic thoughts of patients having depressive illness and evaluated and compared the changes after therapy; i.e. Psychotherapy and pharmacotherapy. Diagnosed cases of depressive illness (n=135), according to ICD-10 and study criteria, attending the out-patient clinic of Department of Psychiatry and Mental Health, Tribhuvan University Teaching Hospital, were included. Beck Depression Inventory was used to screen level of depressive symptoms. Automatic thoughts were assessed by the Automatic Thought Questionnaire-Revised before initiating therapy and after completion of therapy for comparison. Depressive patients received either of the three treatment procedures after randomization of the study sample into three different treatment groups; i.e. Cognitive behavior therapy, pharmacotherapy or combined therapy receiving both cognitive behavior therapy and pharmacotherapy. Among the total 135 patients, 53 (39.3%) had moderate, 47 (34.8%) had severe depressive and 35 (25.9%) had mild depressive symptoms before therapeutic interventions. Negative automatic thoughts were significantly present in depressed patients and reduced after all three interventions. Negative automatic thoughts of hopelessness, anxiety and inability coping were significantly reduced after therapy. Automatic negative thoughts were significantly correlated with depressive disorder. Combined therapy CBT with pharmacotherapy or CBT alone was found to be more effective in modifying automatic negative thoughts than pharmacotherapy alone, ultimately reducing depressive symptoms to a significant degree.

Rumination-focused cognitive behaviour therapy for non-responsive chronic depression: an uncontrolled group study. One-third of patients with depression do not respond satisfactorily to treatment, and approximately 20% of all patients treated for depression develop a chronic depression. One approach to more effective treatment of chronic and treatment-resistant depression is to target rumination - an underlying mechanism implicated in the development and maintenance of depression. The purpose of this uncontrolled group study was to investigate the feasibility of individual rumination-focused cognitive behavioural therapy (RfCBT) for patients with chronic and treatment-resistant depression. A total of 10 patients with chronic and treatment-resistant depression were offered 12-16 individual sessions of RfCBT. The primary outcome was depressive symptoms as measured by Hamilton Depression Scale at pre-, post- and 3-month follow-up. Secondary symptoms measured included self-reported rumination and worry. There was a significant reduction in depressive symptoms (p < 0.05), rumination (p < 0.01) and worry (p < 0.5) from pre- to post-treatment. Half of the participants (n = 5) showed significant reliable change on levels of depressive symptoms post-treatment. The reduction in depressive symptoms, rumination and worry were maintained at follow-up. RfCBT was associated with significant reductions in depressive symptoms in a small sample with chronic and treatment-resistant depression. Despite limitations of being a small uncontrolled study with limited follow-up, these results are promising in a difficult to treat population. RfCBT warrants further systematic evaluation.

Early treatment response in psychotherapy for depression and personality disorder: links with core conflictual relationship themes. Objective: Depressed personality disorder patients showing an early rapid response (or sudden gain) in psychotherapy have better outcomes. Early responders are five times more likely to recover, despite equivalent ratings of working alliance. We explored core conflictual relationship themes (CCRTs) of early responders compared to others to further elucidate process-outcome links. Method: Patients (N=20) with diagnosed major depression and personality disorder received 16 weeks of psychodynamic therapy. Early response was defined as a 50% reduction in Beck Depression Inventory symptoms during the first six sessions. Transcripts of therapy session three for early responders (n=10) and others (n=10) were analyzed using the CCRT Leipzig/Ulm method, identifying 728 components scored by two independent judges. Results: Relationship narratives showed CCRT-wish satisfaction was lower for those not having an early response, for both CCRT "Response of Other" and "Response of Self" components. These patients told narratives of others as more unreliable, aggressive, and less supportive, with less feelings of being loved and a lower experience of being self-determined. Conclusions: Specific negative relationship patterns may inhibit the ability to benefit from both therapy and extra-therapy relationships, contributing to a slower treatment response.

Combining imagination and reason in the treatment of depression: a randomized controlled trial of internet-based cognitive-bias modification and internet-CBT for depression. Computerized cognitive-bias modification (CBM) protocols are rapidly evolving in experimental medicine yet might best be combined with Internet-based cognitive behavioral therapy (iCBT). No research to date has evaluated the combined approach in depression. The current randomized controlled trial aimed to evaluate both the independent effects of a CBM protocol targeting imagery and interpretation bias (CBM-I) and the combined effects of CBM-I followed by iCBT. Patients diagnosed with a major depressive episode were randomized to an 11-week intervention (1 week/CBM-I + 10 weeks/iCBT; n = 38) that was delivered via the Internet with no face-to-face patient contact or to a wait-list control (WLC; n = 31). Intent-to-treat marginal models using restricted maximum likelihood estimation demonstrated significant reductions in primary measures of depressive symptoms and distress corresponding to medium-large effect sizes (Cohen's d = 0.62-2.40) following CBM-I and the combined (CBM-I + iCBT) intervention. Analyses demonstrated that the change in interpretation bias at least partially mediated the reduction in depression symptoms following CBM-I. Treatment superiority over the WLC was also evident on all outcome measures at both time points (Hedges gs = .59-.98). Significant reductions were also observed following the combined intervention on secondary measures associated with depression: disability, anxiety, and repetitive negative thinking (Cohen's d = 1.51-2.23). Twenty-seven percent of patients evidenced clinically significant change following CBM-I, and this proportion increased to 65% following the combined intervention. The current study provides encouraging results of the integration of Internet-based technologies into an efficacious and acceptable form of treatment delivery.

Cognitive psychotherapy treatment decreases peripheral oxidative stress parameters associated with major depression disorder. Studies have already pointed out the contribution of oxidative stress in the pathophysiology of major depressive disorder (MDD). The aim of the present study was to investigate the oxidative-antioxidative systems in MDD and in response to cognitive psychotherapies. Oxidative stress were analyzed in 49 MDD patients at baseline, post-treatment, and follow-up; and 49 control subjects without history of psychiatric disorders. MDD subjects presented an increase in oxidative damage related to control subjects for thiobarbituric acid reactive species (TBARS), nitric oxide, and a decrease in total thiol content. Cognitive psychotherapies were able to counteract peripheral oxidative stress in MDD patients, reducing TBARS levels (p<0.001) in the follow-up, nitric oxide (p<0.001) in the post-treatment and follow-up, and increasing the total thiol content (p<0.01) in the post-treatment and follow-up. Oxidative stress was associated with MDD and the regulation of these parameters might represent an important mechanism associated with the clinical improvement of cognitive psychotherapy.

Cognitive behaviour therapy and inflammation: A systematic review of its relationship and the potential implications for the treatment of depression. There is growing evidence confirming increased inflammation in a subset of adults with depression. The impact of this relationship has mostly been considered in biologically based interventions; however, it also has potential implications for psychological therapies. Cognitive behaviour therapy is the most commonly used psychological intervention for the treatment of depression with theories around its efficacy primarily based on psychological mechanisms. However, cognitive behaviour therapy may have an effect on, and its efficacy influenced by, physiological processes associated with depression. Accordingly, the purpose of this systematic review was to examine the relationship between cognitive behaviour therapy and inflammation. Studies examining the anti-inflammatory effects of cognitive behaviour therapy in people with depression and other medical conditions (e.g. cancer, diabetes and heart disease) were examined. In addition, the relationship between change in inflammatory markers and change in depressive symptoms following cognitive behaviour therapy, and the influence of pre-treatment inflammation on cognitive behaviour therapy treatment response were reviewed. A total of 23 studies investigating the anti-inflammatory effects of cognitive behaviour therapy were identified. In 14 of these studies, at least one reduction in an inflammatory marker was reported, increases were identified in three studies and no change was found in six studies. Three studies examined the relationship between change in inflammation and change in depressive symptoms following cognitive behaviour therapy. In two of these studies, change in depressive symptoms was associated with a change in at least one inflammatory marker. Finally, three studies examined the influence of pre-treatment inflammation on treatment outcome from cognitive behaviour therapy, and all indicated a poorer treatment response in people with higher premorbid inflammation. Preliminary evidence suggests inflammation should be considered within the context of cognitive behaviour therapy, although robust studies examining the relationship are sparse, and heterogeneity between studies and populations examined was high. The potential treatment implications of the bi-directional relationship between inflammation and cognitive behaviour therapy are discussed, and recommendations for future research are proposed.

Benefits of collaborative care for post-CABG depression are not related to adjustments in antidepressant pharmacotherapy. To determine whether the use and adjustment of antidepressant pharmacotherapy accounted for the beneficial effects of collaborative care treatment on the improvement of mood symptoms and health-related quality of life (HRQoL) after coronary artery bypass graft (CABG) surgery. In a post-hoc analysis of data from the Bypassing the Blues (BtB) trial we tested the impact of antidepressant medication on changes in depression and HRQoL from the early postoperative period to 8-month follow-up. Two hundred fifty-nine depressed post-CABG patients scoring ≥10 on the Patient Health Questionnaire-9 were classified in four groups according to whether or not they received antidepressants at baseline and 8-months following randomization. Patients using antidepressant pharmacotherapy at baseline and follow-up tended to be younger and female (p≤0.01), but were similar in various clinical characteristics. Just 24% (63/259) of patients were on an antidepressant at baseline which increased to 36% at follow-up (94/259). Compared to other groups, patients on antidepressants at both baseline and follow-up assessment showed the smallest improvement in mood symptoms and HRQoL. While multivariate analyses confirmed that randomization to collaborative care was associated with greater improvement in mood symptoms (odds ratio [OR]=3.1; 95%-confidence interval [CI]=1.8-5.4, p<0.0001) and mental HRQoL (OR=3.6, CI=1.4-9.3, p=0.01), use of antidepressant medication had no differential impact on either measure (p=0.06 and p=0.92, respectively). The beneficial effects of collaborative care for post-CABG depression were not generated by adjustments in antidepressant medication. Clinicaltrials.gov Identifier: NCT00091962.

Comparative Efficacy of Therapies for Treatment of Depression for Patients Undergoing Maintenance Hemodialysis: A Randomized Clinical Trial. Although depression is common among patients receiving maintenance hemodialysis, data on their acceptance of treatment and on the comparative efficacy of various therapies are limited. To determine the effect of an engagement interview on treatment acceptance (phase 1) and to compare the efficacy of cognitive behavioral therapy (CBT) versus sertraline (phase 2) for treating depression in patients receiving hemodialysis. Multicenter, parallel-group, open-label, randomized controlled trial. (ClinicalTrials.gov: NCT02358343). 41 dialysis facilities in 3 U.S. metropolitan areas. Patients who had been receiving hemodialysis for at least 3 months and had a Beck Depression Inventory-II score of 15 or greater; 184 patients participated in phase 1, and 120 subsequently participated in phase 2. Engagement interview versus control visit (phase 1) and 12 weeks of CBT delivered in the dialysis facility versus sertraline treatment (phase 2). The primary outcome for phase 1 was the proportion of participants who started depression treatment within 28 days. For phase 2, the primary outcome was depressive symptoms measured by the Quick Inventory of Depressive Symptoms-Clinician-Rated (QIDS-C) at 12 weeks. The proportion of participants who initiated treatment after the engagement or control visit did not differ (66% vs. 64%, respectively; P = 0.77; estimated risk difference, 2.1 [95% CI, -12.1 to 16.4]). Compared with CBT, sertraline treatment resulted in lower QIDS-C depression scores at 12 weeks (effect estimate, -1.84 [CI, -3.54 to -0.13]; P = 0.035). Adverse events were more frequent in the sertraline than the CBT group. No randomized comparison was made with no treatment, and persistence of treatment effect was not assessed. An engagement interview with patients receiving maintenance hemodialysis had no effect on their acceptance of treatment for depression. After 12 weeks of treatment, depression scores were modestly better with sertraline treatment than with CBT.

The effects of cognitive behavioural therapy on depression and quality of life in patients with maintenance haemodialysis: a systematic review. Depression is highly prevalent among Haemodialysis (HD) patients and is known to results in a series of adverse outcomes and poor quality of life (QoL). Although cognitive behavioural therapy (CBT) has been shown to improve depressive symptoms and QoL in other chronic illness, there is uncertainty in terms of the effectiveness of CBT in HD patients with depression or depressive symptoms. All randomised controlled trials relevant to the topic were retrieved from the following databases: CINHAL, MEDLINE, PubMed, PsycINFO and CENTRAL. The grey literature, specific journals, reference lists of included studies and trials registers website were also searched. Data was extracted or calculated from included studies that had measured depression and quality of life using valid and reliable tools -this included mean differences or standardised mean differences and 95% confidence intervals. The Cochrane risk of bias tool was used to identify the methodological quality of the included studies. Six RCTs were included with varying methodological quality. Meta-analysis was undertaken for 3 studies that employed the CBT versus usual care. All studies showed that the depressive symptoms significantly improved after the CBT. Furthermore, CBT was more effective than usual care (MD=-5.28, 95%CI -7.9 to -2.65, P=0.37) and counselling (MD=-2.39, 95%CI -3.49 to -1.29), while less effective than sertraline (MD=2.2, 95%CI 0.43 to 3.97) in alleviating depressive symptoms. Additionally, the CBT seems to have a beneficial effect in improving QoL when compared with usual care, while no significant difference was found in QoL score when compared CBT with sertraline. CBT may improve depressive symptoms and QoL in HD patients with comorbid depressive symptoms. However, more rigorous studies are needed in this field due to the small quantity and varied methodological quality in the identified studies.

Internet Cognitive-Behavioral Therapy for Depression in Older Adults With Knee Osteoarthritis: A Randomized Controlled Trial. To determine the efficacy of an internet-based cognitive-behavioral therapy (iCBT) program for depression in older adults with osteoarthritis (OA) of the knee and comorbid major depressive disorder (MDD). We conducted a randomized controlled trial in 69 adults (ages ≥50 years) meeting criteria for MDD and OA of the knee with 1-week postintervention (week 11) and 3-month followup (week 24) end points. Patients were allocated to either a 10-week iCBT program for depression added to treatment as usual (TAU) or to a TAU control group. Primary outcomes were depression symptoms (9-Item Patient Health Questionnaire [PHQ-9]) and psychological distress (Kessler-10 [K-10]). Secondary outcomes included arthritis self-efficacy (Arthritis Self-Efficacy Scale [ASES]), OA pain, stiffness, physical function (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), and physical and mental health (Short Form 12-Item health survey physical component and mental component summaries). Depression status was assessed by blinded diagnostic interview (the Mini-International Neuropsychiatric Interview) at intake and followup. Intent-to-treat analyses indicated between-group superiority of iCBT over TAU on the primary outcomes (PHQ-9: Hedges g = 1.01, 95% confidence interval [95% CI] 0.47, 1.54; K-10: Hedges g = 0.75, 95% CI 0.23, 1.28), at postintervention and 3-month followup (PHQ-9: Hedges g = 0.90, 95% CI 0.36, 1.44; K-10: Hedges g = 0.94, 95% CI 0.41, 1.48), and on secondary OA-specific measures (ASES: Hedges g = -0.81, 95% CI -0.29, -1.33; WOMAC: Hedges g = 0.56-0.65, 95% CI 0.04, 1.18) at the 3-month followup. The majority of iCBT participants (84%) no longer met diagnostic criteria at 3-month followup. Results support the efficacy of an iCBT program (requiring no face-to-face contact) for depression in individuals with comorbid depression and OA of the knee. Importantly, the benefits of the program extended beyond reduced depressive symptoms and distress to include increased self-efficacy and improved pain, stiffness, and physical function at followup.

The (cost) effectiveness of guided internet-based self-help CBT for dialysis patients with symptoms of depression: study protocol of a randomised controlled trial. Only a minority of dialysis patients with depressive symptoms are diagnosed and receive treatment. Depressive symptoms are highly prevalent in this population and are associated with adverse clinical outcomes. Underlying factors for this undertreatment may be the lack of evidence for the safety and effectivity of antidepressant medication, the reluctance of patients to adhere to antidepressant medication, the lack of mental healthcare provision in somatic healthcare environments and end-stage renal disease (ESRD) related physical limitations that complicate face-to-face psychotherapy. Guided Internet-based self-help treatment has demonstrated to be effective for depressive symptoms in other chronic patient populations and may overcome these barriers. The aim of this study is to investigate the (cost) effectiveness of a guided Internet-based self-help intervention for symptoms of depression in dialysis patients. This study is a cluster randomized controlled trial (RCT) that investigates the effectiveness of a 5-week Internet-based self-help Problem Solving Therapy (PST) for depressive symptoms in dialysis patients. Depressive symptoms will be measured using the Beck Depression Inventory - second edition (BDI-II), with a cut-off score of ≥10. We aim to include 206 dialysis patients with depressive symptoms who will be cluster randomized to the intervention or the Care as Usual (CAU) control group. Secondary outcomes will include anxiety symptoms, quality of life, economic costs and clinical outcomes, such as inflammatory factors and hair cortisol levels. Assessments will take place at baseline (T0), 2weeks after intervention (T1) and 6months (T2), 12months (T3) and 18months (T4) after intervention. The control group will be measured at the same time points. Analysis will be based on the intention-to-treat principle. Mixed models will be used to assess the changes within each condition between pre-treatment and post-treatment. If demonstrated to be (cost) effective, Internet-based PST will offer new possibilities to treat dialysis patients with depressive symptoms and to improve their quality of care.

Systematic Review and Meta-analysis of Interventions for Depression and Anxiety in Persons With Rheumatoid Arthritis. Psychiatric comorbidities, such as depression and anxiety, are very common in persons with rheumatoid arthritis (RA) and can lead to adverse outcomes. By appropriately treating these comorbidities, disease-specific outcomes and quality of life may be improved. The aim of this study was to systematically review the literature from controlled trials of treatments for depression and anxiety in persons with RA. We searched multiple online databases from inception until March 25, 2015, without restrictions on language, date, or location of publication. We included controlled trials conducted in persons with RA and depression or anxiety. Two independent reviewers extracted information including trial and participant characteristics. The standardized mean differences (SMDs) of depression or anxiety scores at postassessment were pooled between treatment and comparison groups, stratified by active versus inactive comparators. From 1291 unique abstracts, we included 8 RA trials of depression interventions (6 pharmacological, 1 psychological, 1 both). Pharmacological interventions for depression with inactive comparators (n = 3 trials, 143 participants) did not reduce depressive symptoms (SMD, -0.21; 95% confidence interval [CI], -1.27 to 0.85), although interventions with active comparators (n = 3 trials, 190 participants) did improve depressive symptoms (SMD, -0.79; 95% CI, -1.34 to -0.25). The single psychological trial of depression treatment in RA did not improve depressive symptoms (SMD, -0.44; 95% CI, -0.96 to 0.08). Seven of the trials had an unclear risk of bias. Few trials examining interventions for depression or anxiety in adults with RA exist, and the level of evidence is low to moderate because of the risk of bias and small number of trials.
