A randomized trial of the Positive Thoughts and Action program for depression among early adolescents

Mental Health Interventions in Middle Schools: A 10-Year Review of Research

Schools can play an important role in addressing growing concerns about adolescent mental health. Mental health of high school students has predominantly been the focus in literature with less emphasis on younger adolescents. This review identified articles published in the last decade that described evaluations of middle school-based mental health interventions and randomized participants to an intervention or control condition. Fourteen interventions met the inclusion criteria. About two-thirds of interventions were based on mindfulness or cognitive behavioral therapy. Many trials utilized racially diverse, low-income samples. All interventions were delivered to groups, and three contained a parent component. Five trials increased rigor by using an active control condition. Almost two-thirds of the interventions were effective (p < .10) in reducing at least one depression, anxiety, affect, or internalizing symptom outcome compared to a control group. This article provides information about intervention characteristics, efficacy, theoretical framework, and acceptability/feasibility.

A comparison of the effectiveness of cognitive behavioural interventions based on delivery features for elevated symptoms of depression in adolescents: A systematic review

Background

Depression is a public health problem and common amongst adolescents. Cognitive behavioural therapy (CBT) is widely used to treat adolescent depression but existing research does not provide clear conclusions regarding the relative effectiveness of different delivery modalities.

Objectives

The primary aim is to estimate the relative efficacy of different modes of CBT delivery compared with each other and control conditions for reducing depressive symptoms in adolescents. The secondary aim is to compare the different modes of delivery with regard to intervention completion/attrition (a proxy for intervention acceptability).

Search Methods

The Cochrane Depression, Anxiety and Neurosis Clinical Trials Register was searched in April 2020. MEDLINE, PsycInfo, EMBASE, four other electronic databases, the CENTRAL trial registry, Google Scholar and Google were searched in November 2020, together with reference checking, citation searching and hand-searching of two databases.

Selection Criteria

Randomised controlled trials (RCTs) of CBT interventions (irrespective of delivery mode) to reduce symptoms of depression in young people aged 10-19 years with clinically relevant symptoms or diagnosis of depression were included.

Data Collection and Analysis

Screening and data extraction were completed by two authors independently, with discrepancies addressed by a third author. CBT interventions were categorised as follows: group CBT, individual CBT, remote CBT, guided self-help, and unguided self-help. Effect on depressive symptom score was estimated across validated self-report measures using Hedges' g standardised mean difference. Acceptability was estimated based on loss to follow-up as an odds ratio. Treatment rankings were developed using the surface under the cumulative ranking curve (SUCRA). Pairwise meta-analyses were conducted using random effects models where there were two or more head-to-head trials. Network analyses were conducted using random effects models.

Main Results

Sixty-eight studies were included in the review. The mean age of participants ranged from 10 to 19.5 years, and on average 60% of participants were female. The majority of studies were conducted in schools (28) or universities (6); other settings included primary care, clinical settings and the home. The number of CBT sessions ranged from 1 to 16, the frequency of delivery from once every 2 weeks to twice a week and the duration of each session from 20 min to 2 h. The risk of bias was low across all domains for 23 studies, 24 studies had some concerns and the remaining 21 were assessed to be at high risk of bias. Sixty-two RCTs (representing 6435 participants) were included in the pairwise and network meta-analyses for post-intervention depressive symptom score at post-intervention. All pre-specified treatment and control categories were represented by at least one RCT. Although most CBT approaches, except remote CBT, demonstrated superiority over no intervention, no approaches performed clearly better than or equivalent to another. The highest and lowest ranking interventions were guided self-help (SUCRA 83%) and unguided self-help (SUCRA 51%), respectively (very low certainty in treatment ranking). Nineteen RCTs (3260 participants) were included in the pairwise and network meta-analyses for 6 to 12 month follow-up depressive symptom score. Neither guided self-help nor remote CBT were evaluated in the RCTs for this time point. Effects were generally attenuated for 6- to 12-month outcomes compared to posttest. No interventions demonstrated superiority to no intervention, although unguided self-help and group CBT both demonstrated superiority compared to TAU. No CBT approach demonstrated clear superiority over another. The highest and lowest ranking approaches were unguided self-help and individual CBT, respectively. Sixty-two RCTs (7347 participants) were included in the pairwise and network meta-analyses for intervention acceptability. All pre-specified treatment and control categories were represented by at least one RCT. Although point estimates tended to favour no intervention, no active treatments were clearly inferior. No CBT approach demonstrated clear superiority over another. The highest and lowest ranking active interventions were individual CBT and group CBT respectively. Pairwise meta-analytic findings were similar to those of the network meta-analysis for all analyses. There may be age-based subgroup effects on post-intervention depressive symptoms. Using the no intervention control group as the reference, the magnitudes of effects appear to be larger for the oldest age categories compared to the other subgroups for each given comparison. However, they were generally less precise and formal testing only indicated a significant difference for group CBT. Findings were robust to pre-specified sensitivity analyses separating out the type of placebo and excluding cluster-RCTs, as well as an additional analysis excluding studies where we had imputed standard deviations.

Authors' Conclusions

At posttreatment, all active treatments (group CBT, individual CBT, guided self-help, and unguided self-help) except for remote CBT were more effective than no treatment. Guided self-help was the most highly ranked intervention but only evaluated in trials with the oldest adolescents (16-19 years). Moreover, the studies of guided self-help vary in the type and amount of therapist support provided and longer-term results are needed to determine whether effects persist. The magnitude of effects was generally attenuated for 6- to 12-month outcomes. Although unguided self-help was the lowest-ranked active intervention at post-intervention, it was the highest ranked at follow-up. This suggests the need for further research into whether interventions with self-directed elements enable young people to maintain effects by continuing or revisiting the intervention independently, and whether therapist support would improve long-term outcomes. There was no clear evidence that any active treatments were more acceptable to participants than any others. The relative effectiveness of intervention delivery modes must be taken into account in the context of the needs and preferences of individual young people, particularly as the differences between effect sizes were relatively small. Further research into the type and amount of therapist support that is most acceptable to young people and most cost-effective would be particularly useful.

School-based depression and anxiety prevention programs: An updated systematic review and meta-analysis

Depression and anxiety are often first experienced during childhood and adolescence, and interest in the prevention of these disorders is growing. The focus of this review was to assess the effectiveness of psychological prevention programs delivered in schools, and to provide an update to our previous review from five years ago (Werner-Seidler, Perry, Calear, Newby, & Christensen, 2017). Three electronic databases were systematically searched for published articles of randomised controlled trials (RCTs) evaluating the efficacy of school-based prevention programs until October 2020. There were 130 articles that met inclusion criteria, representing 118 unique trials and 45,924 participants. Small between-group effect sizes for depression (g = 0.21) and anxiety (g = 0.18) were detected immediately post-intervention. Subgroup analyses suggested that targeted prevention programs (for young people with risk factors or symptoms) were associated with significantly greater effect sizes relative to universal programs for depression, which was confirmed by meta-regression. There was also some evidence that external providers conferred some benefit over school-staff delivered programs. Overall, study quality was moderate and no association between risk of bias and effect size was detected. School-delivered psychological prevention programs have small effects in reducing symptoms of depression and anxiety. Refinement of these programs, and knowledge about how they can be sustainably delivered in schools beyond the trial period is now needed for population-level preventive effects.

School-based interventions to prevent anxiety, depression and conduct disorder in children and young people: a systematic review and network meta-analysis

Background

Schools in the UK increasingly have to respond to anxiety, depression and conduct disorder as key causes of morbidity in children and young people.

Objective

The objective was to assess the comparative effectiveness of educational setting-based interventions for the prevention of anxiety, depression and conduct disorder in children and young people.

Design

This study comprised a systematic review, a network meta-analysis and an economic evaluation.

Data sources

The databases MEDLINE, EMBASE™ (Elsevier, Amsterdam, the Netherlands), PsycInfo® (American Psychological Association, Washington, DC, USA) and Cochrane Central Register of Controlled Trials (CENTRAL) were searched to 4 April 2018, and the NHS Economic Evaluation Database (NHS EED) was searched on 22 May 2019 for economic evaluations. No language or date filters were applied.

Main outcomes

The main outcomes were post-intervention self-reported anxiety, depression or conduct disorder symptoms.

Review methods

Randomised/quasi-randomised trials of universal or targeted interventions for the prevention of anxiety, depression or conduct disorder in children and young people aged 4–18 years were included. Screening was conducted independently by two reviewers. Data extraction was conducted by one reviewer and checked by a second. Intervention- and component-level network meta-analyses were conducted in OpenBUGS. A review of the economic literature and a cost–consequence analysis were conducted.

Results

A total of 142 studies were included in the review, and 109 contributed to the network meta-analysis. Of the 109 studies, 57 were rated as having an unclear risk of bias for random sequence generation and allocation concealment. Heterogeneity was moderate. In universal secondary school settings, mindfulness/relaxation interventions [standardised mean difference (SMD) –0.65, 95% credible interval (CrI) –1.14 to –0.19] and cognitive–behavioural interventions (SMD –0.15, 95% CrI –0.34 to 0.04) may be effective for anxiety. Cognitive–behavioural interventions incorporating a psychoeducation component may be effective (SMD –0.30, 95% CrI –0.59 to –0.01) at preventing anxiety immediately post intervention. There was evidence that exercise was effective in preventing anxiety in targeted secondary school settings (SMD –0.47, 95% CrI –0.86 to –0.09). There was weak evidence that cognitive–behavioural interventions may prevent anxiety in universal (SMD –0.07, 95% CrI –0.23 to 0.05) and targeted (SMD –0.38, 95% CrI –0.84 to 0.07) primary school settings. There was weak evidence that cognitive–behavioural (SMD –0.04, 95% CrI –0.16 to 0.07) and cognitive–behavioural + interpersonal therapy (SMD –0.18, 95% CrI –0.46 to 0.08) may be effective in preventing depression in universal secondary school settings. Third-wave (SMD –0.35, 95% CrI –0.70 to 0.00) and cognitive–behavioural interventions (SMD –0.11, 95% CrI –0.28 to 0.05) incorporating a psychoeducation component may be effective at preventing depression immediately post intervention. There was no evidence of intervention effectiveness in targeted secondary, targeted primary or universal primary school settings post intervention. The results for university settings were unreliable because of inconsistency in the network meta-analysis. A narrative summary was reported for five conduct disorder prevention studies, all in primary school settings. None reported the primary outcome at the primary post-intervention time point. The economic evidence review reported heterogeneous findings from six studies. Taking the perspective of a single school budget and based on cognitive–behavioural therapy intervention costs in universal secondary school settings, the cost–consequence analysis estimated an intervention cost of £43 per student.

Limitations

The emphasis on disorder-specific prevention excluded broader mental health interventions and restricted the number of eligible conduct disorder prevention studies. Restricting the study to interventions delivered in the educational setting may have limited the number of eligible university-level interventions.

Conclusions

There was weak evidence of the effectiveness of school-based, disorder-specific prevention interventions, although effects were modest and the evidence not robust. Cognitive–behavioural therapy-based interventions may be more effective if they include a psychoeducation component.

Future work

Future trials for prevention of anxiety and depression should evaluate cognitive–behavioural interventions with and without a psychoeducation component, and include mindfulness/relaxation or exercise comparators, with sufficient follow-up. Cost implications must be adequately measured.

Psychological Treatments for Depression in Adolescents: More Than Three Decades Later

Depression is a common and impairing disorder which is a serious public health problem. For some individuals, depression has a chronic course and is recurrent, particularly when its onset is during adolescence. The purpose of the current paper was to review the clinical trials conducted between 1980 and 2020 in adolescents with a primary diagnosis of a depressive disorder, excluding indicated prevention trials for depressive symptomatology. Cognitive behavioral therapy (CBT) is the pre-eminent treatment and is well established from an evidence-based treatment perspective. The body of research on the remaining treatments is smaller and the status of these treatments is varied: interpersonal therapy (IPT) is well established; family therapy (FT) is possibly effective; and short-term psychoanalytic therapy (PT) is experimental treatment. Implementation of the two treatments that work well-CBT and IPT-has more support when provided individually as compared to in groups. Research on depression treatments has been expanding through using transdiagnostic and modular protocols, implementation through information and communication technologies, and indicated prevention programs. Despite significant progress, however, questions remain regarding the rate of non-response to treatment, the fading of specific treatment effects over time, and the contribution of parental involvement in therapy.

Partnering with School Providers to Co-Design Mental Health Interventions: An Open Trial of Act & Adapt in Urban Public Middle Schools

Schools are well positioned to provide access to youth mental health services, but implementing effective programs that promote emotional and behavioral functioning in school settings is complicated by the poor fit of interventions developed in research settings to complex school contexts. The current study formed a research-practice partnership with two urban public schools and mental health providers employed by those schools (N = 6, 100% female, 50% Black/African American, 50% White/Caucasian) in the adaptation of a depression prevention intervention, Act & Adapt. The intervention was modified by decreasing meeting time and streamlining session content, increasing flexibility, making intervention materials more similar to academic curriculum, and increasing the focus on managing disruptive behavior within group sessions. In an open trial, 6^th grade students (N = 22; 59% boys, 31% Hispanic, 22% Black/African American, 4% Asian, 30% White/Caucasian) at both schools who were identified as clinically "at risk" reported improvements from baseline to post-intervention and at one-year follow-up on measures of emotional and behavioral difficulties and coping strategies, with parallel results by caregiver report. The providers reported satisfaction with the intervention, and qualitative analyses of provider focus groups suggested both barriers and facilitators to research-practice collaborations to implement mental health interventions in schools.

Effects of Preference on Outcomes of Preventive Interventions among Ethnically Diverse Adolescents At-Risk of Depression

Patient-centered care includes efforts to align treatment with patient preferences to improve outcomes and has not been studied in adolescent depression prevention. Within a school-based randomized trial, we examined the effects of offering a preference between two evidence-based preventive interventions for youth at risk of depression, Learning to BREATHE (L2B) and Interpersonal Therapy-Adolescent Skills Training. We examined the effects of 3 preference factors (assignment condition [preference vs. random], receipt of preferred program, and baseline program preference) on outcomes in a diverse sample of 111 adolescents (M age = 15.18 years, SD = .86): 81 (73%) girls, 45 (41%) White, 40 (36%) Asian American, 8 (7%) Latinx, 1 (1%) African American, and 17 (15%) multiracial or other race/ethnicity. Findings revealed little evidence that receiving a preferred intervention or being given a choice of interventions was linked to greater improvement or initial engagement. Further, analyses did not indicate that adolescents with baseline indications for a specific intervention would benefit more from that intervention; rather, adolescents with generally lower baseline functioning improved more regardless of the intervention received. However, receipt of L2B and a baseline preference for L2B were associated with greater improvements in about half of the outcomes examined, with effect sizes ranging from R 2 = 0.04 to 0.14. There was little support for the need to match interventions to adolescent preferences in school-based prevention efforts. Rather, the more scalable mindfulness-based intervention had stronger effects than the interpersonal intervention and may hold promise for diverse adolescents.

Effect of 4 weeks daily wild blueberry supplementation on symptoms of depression in adolescents

Adolescence is an important period for cognitive maturation and emotional regulation, and this age group is particularly vulnerable to developing depression. Diets rich in fruits and vegetables have been associated with decreased risk of developing depressive disorders across the lifespan, maybe due to the high flavonoid content of these foods. Previously, we have shown increases in transient positive affect (PA) in both children and young adults 2 h after administration of a wild blueberry (WBB) intervention. Here, using a randomised double-blind, placebo-controlled trial, we investigated the effects of 4 weeks, daily WBB supplementation (containing about 253 mg anthocyanins) on transient and chronic mood in adolescents. Healthy 12-17-year old (n 64, thirty-five females) participants were randomly assigned to receive either a WBB or matched placebo supplementation. Depression and anxiety symptoms were assessed before and after the intervention period using the Mood and Feeling Questionnaire and Revised Child Anxiety and Depression Scale. Transient affect was assessed before, 2 weeks and at 4 weeks using PA and negative affect. Following the intervention period, there were significantly fewer self-reported depression symptoms in participants who were supplemented with WBB compared with placebo (P = 0·02, 95 % CI -6·71, -5·35). There was no between-group effect on anxiety symptoms or on transient affect. Further investigation is required to identify specific mechanisms that link flavonoids consumption and mood. If replicated, the observed effects of WBB supplementation may be a potential prevention strategy for adolescent depression and may have benefits for public mental health.

Evidence Base Update for Measures of Social Skills and Social Competence in Clinical Samples of Youth

Social skills and social competence are key transdiagnostic processes in developmental psychopathology and are the focus of an array of clinical interventions. In this Evidence Base Update, we evaluated the psychometric properties of measures of social skills and social competence used with clinical samples of children and adolescents. A systematic literature search yielded eight widely used measures of social skills and one measure of social competence. Applying the criteria identified by Youngstrom et al. (2017), we found that, with some exceptions, these measures had adequate to excellent norms, internal consistency, and test-retest reliability. There was at least adequate evidence of construct validity and treatment sensitivity in clinical samples for nearly all measures assessed. Many of the scales included items assessing constructs other than social skills and competence (e.g., emotion regulation). Development of updated tools to assess youth's effectiveness in key interpersonal situations, including those occurring online, may yield clinical dividends.

Practitioner Review: Effectiveness of indicated school-based interventions for adolescent depression and anxiety - a meta-analytic review

BACKGROUND

Interest in delivering psychological interventions within schools to facilitate early intervention is increasing. However, most reviews have focused on universal or preventative programmes rather than interventions designed to decrease existing symptoms of depression or anxiety. This paper aims to provide a meta-analytic review of randomised controlled trials of indicated psychological interventions for young people aged 10-19 with elevated symptoms of depression and/or anxiety.

METHODS

Eight electronic databases were systematically searched from inception to April 2019 for eligible trials. Study quality was assessed using two scales designed to evaluate psychotherapy intervention trials. Random effects meta-analyses were conducted separately for trials that recruited participants based on symptoms of depression and based on symptoms of anxiety.

RESULTS

Data from 45 trials were analysed. Most interventions studied used cognitive and behavioural strategies. Few studies met methodological quality criteria, but effect size was not associated with study quality. Indicated school-based interventions had a small effect on reducing depression symptoms (SMD = .34, 95% CI -0.48, -0.21) and a medium effect on reducing anxiety symptoms (SMD = -.49, 95% CI -0.79, -0.19) immediately postintervention. Subgroup analyses indicated that interventions delivered by internal school staff did not have significant effects on symptoms. Reductions in depression were maintained at short-term (≤6 months) but not medium (>6 months ≤ 12) or long-term (>12-month) follow-up. Reductions in anxiety symptoms were not maintained at any follow-up.

CONCLUSIONS

Indicated school-based interventions are effective at reducing symptoms of depression and anxiety in adolescents immediately postintervention but there is little evidence that these reductions are maintained. Interventions delivered by school staff are not supported by the current evidence base. Further high-quality randomised controlled trials incorporating assessment of longer-term outcomes are needed to justify increased investment in school-based interventions for adolescent depression and anxiety.

Meta-Analysis: 13-Year Follow-up of Psychotherapy Effects on Youth Depression

OBJECTIVE

Youth depression is a debilitating condition that constitutes a major public health concern. A 2006 meta-analysis found modest benefits for psychotherapy versus control. Has 13 more years of research improved that picture? We sought to find out.

METHOD

We searched PubMed, PsychINFO, and Dissertation Abstracts International for 1960 to 2017, identifying 655 randomized, English-language psychotherapy trials for individuals aged 4 to 18 years. Of these, 55 assessed psychotherapy versus control for youth depression with outcome measures administered to both treatment and control conditions at post (κ = 53) and/or follow-up (κ = 32). Twelve study and outcome characteristics were extracted, and effect sizes were calculated for all psychotherapy versus control comparisons. Using a three-level random-effects model, we obtained an overall estimate of the psychotherapy versus control difference while accounting for the dependency among effect sizes. We then fitted a three-level mixed-effects model to identify moderators that might explain variation in effect size within and between studies.

RESULTS

The overall effect size (g) was 0.36 at posttreatment and 0.21 at follow-up (averaging 42 weeks after posttreatment). Three moderator effects were identified: effects were significantly larger for interpersonal therapy than for cognitive behavioral therapy, for youth self-reported outcomes than parent-reports, and for comparisons with inactive control conditions (eg, waitlist) than active controls (eg, usual care). Effects showed specificity, with significantly smaller effects for anxiety and externalizing behavior outcomes than for depression measures.

CONCLUSION

Youth depression psychotherapy effects are modest, with no significant change over the past 13 years. The findings highlight the need for treatment development and research to improve both immediate and longer-term benefits.

A Systematic Review and Meta-Analysis of School-Based Stress, Anxiety, and Depression Prevention Programs for Adolescents

Given the recent rise in adolescent mental health issues, many researchers have turned to school-based mental health programs as a way to reduce stress, anxiety, and depressive symptoms among large groups of adolescents. The purpose of the current systematic review and meta-analysis is to identify and evaluate the efficacy of school-based programming aimed at reducing internalizing mental health problems of adolescents. A total of 42 articles, including a total of 7310 adolescents, ages 11-18, met inclusion for the meta-analyses. Meta-analyses were completed for each of the three mental health outcomes (stress, depression, and anxiety) and meta-regression was used to determine the influence of type of program, program dose, sex, race, and age on program effectiveness. Overall, stress interventions did not reduce stress symptoms, although targeted interventions showed greater reductions in stress than universal programs. Overall, anxiety interventions significantly reduced anxiety symptoms, however higher doses may be necessary for universal programs. Lastly, depression interventions significantly reduced depressive symptoms, but this reduction was moderated by a combination of program type, dose, race, and age group. Although, school-based programs aimed at decreasing anxiety and depression were effective, these effects are not long-lasting. Interventions aimed at reducing stress were not effective, however very few programs targeted or included stress as an outcome variable. Implications for practice, policy and research are discussed.

The Efficacy of Psychological Capital Intervention (PCI) for Depression From the Perspective of Positive Psychology: A Pilot Study

Extensive psychological interventions primarily target the negative symptoms of depression and the deficits in positive resources have been systematically neglected. So far, little attention has been devoted to psychological capital (PsyCap) intervention from the perspective of developing positive resources. The aim of the present pilot study was to evaluate the efficacy of psychological capital intervention (PCI) for depression in a randomized controlled trial. A total of 56 patients were randomized to either care as usual (CAU) for normal medication or psychological capital intervention (PCI) group, where the normal medication was supplemented with the PCI. Participants were assessed at pre- and post-treatment, as well as 6-month follow-up, on measures of depressive symptoms and PsyCap. The PCI group displayed significantly larger improvements in PsyCap and larger reductions in depression symptoms from pre- to post treatment compared to control group. Improvements were sustained over the 6-month follow-up period. Targeting the positive resources intervention in the PCI may be effective against the treatment of depression.

Trajectories of change in maternal and adolescent depressive symptoms in the depression prevention initiative

BACKGROUND

Given the prevalence and consequences of adolescent depression, depression prevention has become an important area of research. While prevention programs like Interpersonal Psychotherapy - Adolescent Skills Training (IPT-AST) have demonstrated effectiveness, little research to date has studied the relationship between maternal depression and adolescent outcomes in these programs.

METHOD

The current study investigated the relationship between maternal and adolescent depressive symptoms in 167 mother-adolescent dyads who were enrolled in the Depression Prevention Initiative (DPI), a randomized controlled trial that compared IPT-AST to group counseling (GC). First, the study examined the relationship between initial levels of adolescent and maternal depressive symptoms. The study then investigated whether maternal depressive symptoms improved over the two-year study period. Finally, the study assessed whether maternal and adolescent symptoms changed concurrently across time.

RESULTS

Results indicated that initial levels of maternal and adolescent symptoms were positively associated. Additionally, maternal symptoms improved across the two-year period. Maternal and adolescent outcomes were related across time: as adolescents improved in our study, their mothers also improved.

LIMITATIONS

The study utilized self-report data only and did not allow for the testing of causality in the relationship between mother-youth depression.

CONCLUSIONS

These findings add to the literature demonstrating that as one part of the mother-child dyad improves, the other improves as well. These findings extend the current understanding of the relationship between maternal and adolescent depressive symptom outcomes, and have important implications for the prevention and treatment of depression.

Indicated preventive interventions for depression in children and adolescents: A meta-analysis and meta-regression

Depression contributes about 2% to the global burden of disease. A first onset of depressive disorder or subsyndromal depressive symptoms is common in adolescence, indicating that early prevention is a priority. However, trials of preventive interventions for depression in youths show conflicting results. This systematic review and meta-analysis investigated the effectiveness of group-based cognitive behavioral therapy (GB-CBT) as a preventive intervention targeting subsyndromal depression in children and adolescents. In addition, the impact of different covariates (type of comparator and use of booster sessions) was assessed. Relevant articles were identified from previous systematic reviews, and supplemented with an electronic search spanning from 01/09/2014 to 28/02/2018. The retrieved articles were assessed for eligibility and risk of bias. Relevant data were extracted. Intervention effectiveness was pooled using a random-effects model and the impact of covariates assessed using meta-regression. 38 eligible articles (34 trials) were obtained. The analysis showed GB-CBT to significantly reduce the incidence (relative risk 0.43, 95% CI 0.21-0.87) and symptoms (Cohen's d -0.22, 95% CI -0.32 to -0.11) of depression at post-test compared to all controls. Comparisons with passive comparators suggested that the effect decayed over time. However, compared to active controls, a significant intervention effect was evident only after 12 month or more. Our results suggest that the preventive effect of GB-CBT wears off, but still lasts longer than the effect of active comparators. Only a few studies included booster sessions, precluding firm conclusions. Future studies should clarify to what extent maintenance strategies can prolong the preventive effect of GB-CBT.

SCHOOL-RELATED OUTCOMES FROM A RANDOMIZED CONTROLLED TRIAL OF ADOLESCENT DEPRESSION PREVENTION PROGRAMS

Previous research has demonstrated the effectiveness of school-based depression prevention programs in reducing depressive symptoms and improving functioning. This study examined whether these programs have positive effects on school-related outcomes. Students at 10 middle and high schools in New Jersey were randomized to weekly sessions of Interpersonal Psychotherapy - Adolescent Skills Training (IPT-AST) or group counseling (GC). Analyses examined whether there were intervention effects on participants' grades, attendance rates, and disciplinary outcomes over approximately one year post-intervention. Although there were no significant main effects of intervention condition, moderation analyses indicated more favorable effects of IPT-AST among certain higher-risk subgroups (e.g., those from low-income families). Participants who experienced meaningful improvement in their depressive symptoms had significantly more positive outcomes on overall grades than those who did not experience meaningful improvement, regardless of intervention condition. Further research is needed to clarify the effects of depression prevention programs on these school-related outcomes.

A non-randomised pragmatic trial of a school-based group cognitive-behavioural programme for preventing depression in girls

The aim of this study was to investigate the effectiveness of the DISA-programme in preventing depressive symptoms (DS) in adolescent girls, as implemented in a real-world school setting, accounting for baseline socioeconomic and psychosocial factors, and to investigate whether the effects of these baseline variables on DS differed between intervention participants and non-participants. In this non-randomised pragmatic trial, an electronic questionnaire was disseminated in 2011 (baseline) and 2012 (follow-up) in schools in one municipality in northern Sweden. Pupils (total n=275; intervention participants identified in the questionnaire: n=53; non-participants: n=222) were 14–15 years old at baseline. The groups were compared by means of SEM. DISA could not predict differences in DS at follow-up in this real-life setting. In the overall sample, sexual harassment victimisation (SH) at baseline was associated with DS at follow-up and the estimate for SH increased in the DISA-participants compared to the overall sample.

Parental involvement in adolescent depression interventions: A systematic review of randomized clinical trials

Despite the widespread research recommendations for psychiatric nurses and other mental health professionals to include parents in adolescent depression treatment, no systematic reviews have yet synthesized the findings from intervention studies that included parents in the treatment and/or prevention of adolescent depression. Therefore, this systematic review was conducted to (i) identify and describe clinical trials that included parents as an integral component of adolescent depression interventions, (ii) examine the effectiveness of these trials in reducing depressive symptoms, and (iii) evaluate their methodological quality. We systematically searched the databases PubMed and PsycINFO. The search strategy adhered to the PRISMA statement to guide identification and selection of articles. Further, a structured evaluation form was adapted from the CONSORT statement and methodological literature to evaluate the elicited clinical trials. A total of 288 unique articles met criteria for abstract level screening, 45 articles were selected for full-text review, and 16 articles were included in the final analysis. We found that (i) available approaches to include parents in adolescent depression interventions vary in their theoretical stance, purpose, sample characteristics, and measured outcomes, (ii) the health outcomes of these approaches seemed to be contingent upon the nature of parental involvement, and (iii) effective translation of these approaches into practice needs to be considered in the light of their methodological rigour. Our review revealed a variety of promising approaches to utilize the parental and family contexts as a means of preventing or treating adolescent depression. However, more research is needed to determine which interventions, within what contexts, and using what resources will facilitate the best health outcomes for adolescents with depression and their parents.

Efficacy of an indicated intervention program for Indian adolescents with subclinical depression

Subclinical depressive symptoms in adolescents are associated with a host of impairments and constitute a risk factor for future depression. The aim of the present study was to study the efficacy of a school-based group coping skills program for Indian adolescents with subclinical depression. Adolescents (n = 120) across two schools comprised the intervention and control groups and were assessed at baseline, post-intervention, and 3 months no-contact follow-up. The intervention group adolescents received the 8-weekly Coping Skills program in same-gender groups of 4-8 adolescents each, and the control group adolescents received one interactive psycho-educatory session. The intervention group evidenced clinically significant reductions in depressive symptoms, negative cognitions, and academic stress, and increased social problem solving and coping skills, at both post-intervention and follow-up. With regard to moderators, initial levels of depressive symptoms and homework compliance were found to partially moderate the effect of intervention. No effects were found for parental depression, gender, and age. The present study calls for future development and implementation of programs to address subclinical psychopathology among adolescents in Indian schools.

Generalizability of Clinical Trial Results for Adolescent Major Depressive Disorder

BACKGROUND

Although there have been a number of clinical trials evaluating treatments for adolescents with major depressive disorder (MDD), the generalizability of those trials to samples of depressed adolescents who present for routine clinical care is unknown. Examining the generalizability of clinical trials of pharmacological and psychotherapy interventions for adolescent depression can help administrators and frontline practitioners determine the relevance of these studies for their patients and may also guide eligibility criteria for future clinical trials in this clinical population.

METHODS

Data on nationally representative adolescents were derived from the National Comorbidity Survey: Adolescent Supplement. To assess the generalizability of adolescent clinical trials for MDD, we applied a standard set of eligibility criteria representative of clinical trials to all adolescents in the National Comorbidity Survey: Adolescent Supplement with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of MDD (N = 592).

RESULTS

From the overall MDD sample, 61.9% would have been excluded from a typical pharmacological trial, whereas 42.2% would have been excluded from a psychotherapy trial. Among those who sought treatment (n = 412), the corresponding exclusion rates were 72.7% for a pharmacological trial and 52.2% for a psychotherapy trial. The criterion leading to the largest number of exclusions was "significant risk of suicide" in both pharmacological and psychotherapy trials.

CONCLUSIONS

Pharmacological and, to a lesser extent, psychotherapy clinical trials likely exclude most adolescents with MDD. Careful consideration should be given to balancing eligibility criteria and internal validity with applicability in routine clinical care while ensuring patient safety.

A Comparison of Early Adolescent Behavioral Health Risks Among Urban American Indians/Alaska Natives and their Peers

We sought to examine behavioral health indicators for an early adolescent population of American Indians/Alaska Natives (AI/AN) within an urban setting in Washington State. We conducted secondary data analyses from a randomized clinical trial implemented in local middle schools that compared AI/ANs (n = 43), non-Hispanic Whites (n = 620), and other racial/ethnic minority youth (n = 527) across a variety of behavioral health risks. AI/AN youth reported significantly more depressive symptoms than other racial/ethnic minorities as well as non-Hispanic Whites. They also reported more discrimination, more generalized anxiety, and were more likely to have initiated substance use, in comparison to non-Hispanic Whites. Psychosocial screening and early intervention are critically needed for AI/AN youth.

Twelve-Month Outcomes of a Randomized Trial of the Positive Thoughts and Action Program for Depression Among Early Adolescents

This study was conducted to examine the 12-month effects on depression and depressive symptoms of a group-based cognitive-behavioral preventive intervention for middle school students (Positive Thoughts and Actions, or PTA), relative to a brief, individually administered supportive intervention (Individual Support Program, or ISP). A randomized clinical trial was conducted with 120 early adolescents (73 girls and 47 boys; age 12-14 years) drawn from a school-based population who had elevated depressive symptoms. Youths completed measures of depressive symptoms at baseline, post-intervention, and 6 and 12 months into the follow-up phase. Measures of internalizing problems, externalizing problems, school adjustment, interpersonal relationships, and health behavior were obtained from parents and/or youth. Multilevel models indicated that the effect of PTA on youth-reported depressive symptoms persisted until 12-month follow-up; d = 0.36 at post-intervention, d = 0.24 at 6-month follow-up, and d = 0.21 at 12-month follow-up. PTA youths also reported lower internalizing symptoms at post-intervention, d = 0.44, and at 12-month follow-up, d = 0.39. Time-limited effects were found for parent-reported internalizing symptoms and health behavior. Onset of new depressive episodes did not differ based on intervention group (21 % ISP; 17 % PTA). Results demonstrate support for the long-term efficacy of PTA, a cognitive-behavioral preventive intervention in which youths engage in personal goal-setting and practice social-emotional skills.

Supporting Students: A GRADE Analysis of the Research on Student Wellness and Classroom Mental Health Support

Recommendations derived from research evidence regarding program implementation in school-based mental health [SBMH] require knowledge of the intervention outcomes as well as the potential to translate program components into schools. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) analysis was applied to major areas of the SBMH literature in addressing the areas of effectiveness and the strength of recommendation in implementation. Nine areas were addressed: emotional intelligence, stigma reduction, mindfulness, anxiety, depression, addictions, suicide prevention, trauma, and eating disorders. Ninety-eight studies were retrieved across the nine areas. Effect sizes based on reported outcomes and estimates on the strength of recommendation were generated in each of the nine areas of interest. These results provide an overview of the quality of the evidence that will be of relevance to school personal in making program selections.

Cognitive behavioural therapy (CBT), third-wave CBT and interpersonal therapy (IPT) based interventions for preventing depression in children and adolescents

BACKGROUND

Depression is common in young people. It has a marked negative impact and is associated with self-harm and suicide. Preventing its onset would be an important advance in public health. This is an update of a Cochrane review that was last updated in 2011.

OBJECTIVES

To determine whether evidence-based psychological interventions (including cognitive behavioural therapy (CBT), interpersonal therapy (IPT) and third wave CBT)) are effective in preventing the onset of depressive disorder in children and adolescents.

SEARCH METHODS

We searched the specialised register of the Cochrane Common Mental Disorders Group (CCMDCTR to 11 September 2015), which includes relevant randomised controlled trials from the following bibliographic databases: The Cochrane Library (all years), EMBASE (1974 to date), MEDLINE (1950 to date) and PsycINFO (1967 to date). We searched conference abstracts and reference lists of included trials and reviews, and contacted experts in the field.

SELECTION CRITERIA

We included randomised controlled trials of an evidence-based psychological prevention programme compared with any comparison control for young people aged 5 to 19 years, who did not currently meet diagnostic criteria for depression.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trials for inclusion and rated their risk of bias. We adjusted sample sizes to take account of cluster designs and multiple comparisons. We contacted trial authors for additional information where needed. We assessed the quality of evidence for the primary outcomes using GRADE.

MAIN RESULTS

We included 83 trials in this review. The majority of trials (67) were carried out in school settings with eight in colleges or universities, four in clinical settings, three in the community and four in mixed settings. Twenty-nine trials were carried out in unselected populations and 53 in targeted populations.For the primary outcome of depression diagnosis at medium-term follow-up (up to 12 months), there were 32 trials with 5965 participants and the risk of having a diagnosis of depression was reduced for participants receiving an intervention compared to those receiving no intervention (risk difference (RD) -0.03, 95% confidence interval (CI) -0.05 to -0.01; P value = 0.01). We rated this evidence as moderate quality according to the GRADE criteria. There were 70 trials (73 trial arms) with 13,829 participants that contributed to the analysis for the primary outcome of depression symptoms (self-rated) at the post-intervention time point, with results showing a small but statistically significant effect (standardised mean difference (SMD) -0.21, 95% CI -0.27 to -0.15; P value < 0.0001). This effect persisted to the short-term assessment point (up to three months) (SMD -0.31, 95% CI -0.45 to -0.17; P value < 0.0001; 16 studies; 1558 participants) and medium-term (4 to 12 months) assessment point (SMD -0.12, 95% CI -0.18 to -0.05; P value = 0.0002; 53 studies; 11,913 participants); however, the effect was no longer evident at the long-term follow-up. We rated this evidence as low to moderate quality according to the GRADE criteria.The evidence from this review is unclear with regard to whether the type of population modified the overall effects; there was statistically significant moderation of the overall effect for depression symptoms (P value = 0.0002), but not for depressive disorder (P value = 0.08). For trials implemented in universal populations there was no effect for depression diagnosis (RD -0.01, 95% CI -0.03 to 0.01) and a small effect for depression symptoms (SMD -0.11, 95% CI -0.17 to -0.05). For trials implemented in targeted populations there was a statistically significantly beneficial effect of intervention (depression diagnosis RD -0.04, 95% CI -0.07 to -0.01; depression symptoms SMD -0.32, 95% CI -0.42 to -0.23). Of note were the lack of attention placebo-controlled trials in targeted populations (none for depression diagnosis and four for depression symptoms). Among trials implemented in universal populations a number used an attention placebo comparison in which the intervention consistently showed no effect.

AUTHORS' CONCLUSIONS

Overall the results show small positive benefits of depression prevention, for both the primary outcomes of self-rated depressive symptoms post-intervention and depression diagnosis up to 12 months (but not beyond). Estimates of numbers needed to treat to benefit (NNTB = 11) compare well with other public health interventions. However, the evidence was of moderate to low quality using the GRADE framework and the results were heterogeneous. Prevention programmes delivered to universal populations showed a sobering lack of effect when compared with an attention placebo control. Interventions delivered to targeted populations, particularly those selected on the basis of depression symptoms, had larger effect sizes, but these seldom used an attention placebo comparison and there are practical difficulties inherent in the implementation of targeted programmes. We conclude that there is still not enough evidence to support the implementation of depression prevention programmes.Future research should focus on current gaps in our knowledge. Given the relative lack of evidence for universal interventions compared with attention placebo controls and the poor results from well-conducted effectiveness trials of universal interventions, in our opinion any future such trials should test a depression prevention programme in an indicated targeted population using a credible attention placebo comparison group. Depressive disorder as the primary outcome should be measured over the longer term, as well as clinician-rated depression. Such a trial should consider scalability as well as the potential for the intervention to do harm.

Mediators and Moderators of a School-Based Cognitive-Behavioral Depression Prevention Program

This study tested potential moderators and mediators of an indicated depression prevention program for middle school students, Positive Thoughts and Actions (PTA). Participants were 120 students randomly assigned to PTA, or a brief, individually administered supportive intervention (Individual Support Program, or ISP). Youths completed measures of depressive symptoms at baseline, post-intervention, and 12-month follow-up. Hierarchical regression was used to test three moderators-ethnic minority status, gender, and baseline depressive symptoms-and three mediators representing functional outcomes targeted by PTA-parent-child communication, attitude towards school, and health behavior. Ethnic minority status did not moderate PTA effects at post-intervention but did moderate PTA effects at 12-month follow-up. At 12 months, PTA appeared to be more effective for White participants than ethnic minority youth. Follow-up analyses suggested this moderation effect was due to the tendency of ethnic minority youth, especially those with fewer symptoms at baseline, to drop out by 12 months. Neither gender nor baseline depressive symptoms moderated the effects of PTA. Although PTA improved health behavior and attitudes toward school, there was no evidence that any of these functional outcomes measured mediated the impact of PTA on depressive symptoms. Future directions are discussed.

A Randomized Depression Prevention Trial Comparing Interpersonal Psychotherapy--Adolescent Skills Training to Group Counseling in Schools

Given the rise in depression disorders in adolescence, it is important to develop and study depression prevention programs for this age group. The current study examined the efficacy of Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST), a group prevention program for adolescent depression, in comparison to group programs that are typically delivered in school settings. In this indicated prevention trial, 186 adolescents with elevated depression symptoms were randomized to receive IPT-AST delivered by research staff or group counseling (GC) delivered by school counselors. Hierarchical linear modeling examined differences in rates of change in depressive symptoms and overall functioning from baseline to the 6-month follow-up assessment. Cox regression compared rates of depression diagnoses. Adolescents in IPT-AST showed significantly greater improvements in self-reported depressive symptoms and evaluator-rated overall functioning than GC adolescents from baseline to the 6-month follow-up. However, there were no significant differences between the two conditions in onset of depression diagnoses. Although both intervention conditions demonstrated significant improvements in depressive symptoms and overall functioning, results indicate that IPT-AST has modest benefits over groups run by school counselors which were matched on frequency and duration of sessions. In particular, IPT-AST outperformed GC in reduction of depressive symptoms and improvements in overall functioning. These findings point to the clinical utility of this depression prevention program, at least in the short-term. Additional follow-up is needed to determine the long-term effects of IPT-AST, relative to GC, particularly in preventing depression onset.

Major Depressive Disorder Among Children and Adolescents

Depression among youths remains a public health concern, particularly because only a fraction of affected youths receive treatment. To obtain treatment, youths with depression must first be identified so that early intervention can occur. Furthermore, investigation of both more effective pharmacological agents and more widespread accessibility of cognitive-behavioral interventions are necessary. To address unmet needs in the identification and treatment of depression among youths, clinical counseling programs are being developed in primary care clinics and in schools to identify and treat depressive symptoms or milder major depressive disorder and have shown promising outcomes thus far in reducing depression and increasing quality of life.

Comparative efficacy and acceptability of psychotherapies for depression in children and adolescents: A systematic review and network meta-analysis

Previous meta-analyses of psychotherapies for child and adolescent depression were limited because of the small number of trials with direct comparisons between two treatments. A network meta-analysis, a novel approach that integrates direct and indirect evidence from randomized controlled studies, was undertaken to investigate the comparative efficacy and acceptability of psychotherapies for depression in children and adolescents. Systematic searches resulted in 52 studies (total N=3805) of nine psychotherapies and four control conditions. We assessed the efficacy at post-treatment and at follow-up, as well as the acceptability (all-cause discontinuation) of psychotherapies and control conditions. At post-treatment, only interpersonal therapy (IPT) and cognitive-behavioral therapy (CBT) were significantly more effective than most control conditions (standardized mean differences, SMDs ranged from -0.47 to -0.96). Also, IPT and CBT were more beneficial than play therapy. Only psychodynamic therapy and play therapy were not significantly superior to waitlist. At follow-up, IPT and CBT were significantly more effective than most control conditions (SMDs ranged from -0.26 to -1.05), although only IPT retained this superiority at both short-term and long-term follow-up. In addition, IPT and CBT were more beneficial than problem-solving therapy. Waitlist was significantly inferior to other control conditions. With regard to acceptability, IPT and problem-solving therapy had significantly fewer all-cause discontinuations than cognitive therapy and CBT (ORs ranged from 0.06 to 0.33). These data suggest that IPT and CBT should be considered as the best available psychotherapies for depression in children and adolescents. However, several alternative psychotherapies are understudied in this age group. Waitlist may inflate the effect of psychotherapies, so that psychological placebo or treatment-as-usual may be preferable as a control condition in psychotherapy trials.
