Effects of psychotherapy for depression in children and adolescents: a meta-analysis

Trajectories of Chinese adolescent depression before and after COVID-19: A cross-temporal meta-analysis with segmented regression

BACKGROUND

The COVID-19 pandemic has had a profound impact on adolescent mental health, particularly in China. However, there is a lack of research examining the trends in depressive symptom levels among Chinese adolescents before and after the pandemic. This study aims to investigate the changes in depressive symptom levels among Chinese adolescents pre- and post-pandemic and to identify the factors influencing these changes.

METHODS

English-language databases (Web of Science, PubMed, Scopus, ProQuest, and Wiley) and Chinese-language databases (CNKI, VIP, and Wanfang) were searched for relevant studies. A total of 90 articles (91 studies) were included in the cross-temporal meta-analysis (N = 473,781), all of which used the Patient Health Questionnaire-9 (PHQ-9) to measure depressive symptoms in Chinese adolescents. The data for these studies were collected over the period from 2010 to 2023.

RESULTS

Findings indicated that: (1) From 2010 to 2020, year was not a significant predictor of adolescent depressive symptom levels, whereas from 2021 to 2023, year became a significant positive predictor. (2) From 2010 to 2020, females exhibited a more pronounced decrease in depressive symptom levels compared to males; however, from 2021 to 2023, gender differences were not significant. (3) From 2010 to 2020, previous social connectedness, including family size three years prior, divorce rate one year prior, and urbanization level three years prior, significantly and negatively predicted the current year's adolescent depressive symptom levels; however, from 2021 to 2023, the predictive effect of all social indicators was not significant.

CONCLUSIONS

This study enhances the understanding of the mechanisms underlying depression among Chinese adolescents and provides a foundation for decision-making in prevention and intervention strategies.

Craftwell: a feasibility and acceptability study of outdoor heritage crafting for wellbeing and mental health

Background

There has been increasing interest in creativity, heritage and nature to improve health-related outcomes. However, limited research has examined the intersection of heritage crafting in the context of natural spaces. This study aims to explore the feasibility and acceptability of an archaeologically informed outdoor heritage crafting intervention.

Methods

A mixed-methods single group before and after feasibility study was conducted. Participants completed questionnaires, including validated items measuring outcomes related to mental health, wellbeing, social connectedness, mindfulness, perceived state of flow and the connection with nature and the environment. Qualitative interviews were conducted with participants to explore their experiences, and data were analyzed using thematic analysis.

Results

Forty-eight participants from a University in the United Kingdom attended the workshops, achieving the recruitment target within the required timeframe. The response rate to all pre-workshop measures was 100% and remained at 100% post-workshop, with the exception of missing data for two participants (4.2%) for measures assessing wellbeing and anxiety, and missing data for five participants (10.4%) for the measure assessing depression. Therefore, response and retention rates indicate high levels of feasibility to conduct a robust evaluation of this intervention. Five themes were identified, including: participant motivation to sign up; engaging with creative activities in a natural setting; skilled facilitation and a flexible approach; group delivery, and duration and frequency of workshops. Overall, the workshops were positively received by participants, primarily attributing their satisfaction to engagement with group-based creative activities in a natural setting with an educational component.

Conclusion

This study has shown it is feasible and acceptable to deliver and evaluate an archaeologically informed heritage crafting intervention to support wellbeing. These results suggest the need for formal testing of the potential health benefits of the intervention to address policy imperatives for developing and implementing community- and place-based approaches to support mental health.

Treating the Psychological Distress in Children with Adventitious Blindness

Less than half of those who need mental health counseling receive it globally, underscoring the urgent need for psychology-focused intervention. According to data, 30.9% of Nigerians experience psychological anguish. This study investigated the efficacy and moderators of group cognitive behaviour therapy in psychologically distressed schoolchildren with adventitious blindness in Nigeria. A total of 98 students with adventitious blindness were recruited and participated in this study. The participants were assessed at three points using Perceived Emotional Distress Inventory. A mixed model ANCOVA with repeated measures shows that the CBT treatment had a dependable significant effect in decreasing psychological distress. The results showed that sociodemographic factors do not significantly moderate the efficacy of CBT treatment on the reduction of psychological distress in schoolchildren with adventitious blindness. In conclusion, the effect of a group cognitive behavioural therapy had a consistent significant reduction in psychological distress and none of their sociodemographic characteristics moderated the effects. Therefore, cognitive-behavioural practitioners should collaborate with special schools to diagnose and provide CBT treatment to schoolchildren living with adventitious blindness.

Transdiagnostic Sleep and Circadian Intervention in Youth: Long-Term Follow-Up of a Randomized Controlled Trial

OBJECTIVE

This preregistered study compared the effects of the Transdiagnostic Sleep and Circadian Intervention (TranS-C) with psychoeducation (PE) about sleep, health, yoga, meditation, and outdoor appreciation activities on sleep and circadian functioning, health risk, and sleep health behaviors at long-term follow-up (LTFU), an average of 8 years following treatment. We also examined if more sleep health behaviors at LTFU were associated with better sleep and circadian functioning at LTFU and if better sleep and circadian functioning were associated with lower health risk at LTFU.

METHOD

At baseline, we randomly assigned adolescents with an eveningness chronotype to TranS-C (n = 89) or PE (n = 87). Of this sample, we assessed 106 young adults (mean age at follow-up = 22.5 years; n = 55 from TranS-C; n = 51 from PE) an average of 8 years following treatment.

RESULTS

Despite TranS-C (vs PE) sustaining improvement in circadian functioning through 12-month follow-up, at LTFU, there were no significant differences between the conditions on any outcome, including sleep and circadian functioning, risks in 5 health domains indexed by self-report and ecological momentary assessment, sleep health behaviors, and physical measurements. Across both conditions, measures indicating poorer sleep and circadian functioning were associated with higher health risk across multiple domains, and more sleep health behaviors were associated with lower levels of eveningness at LTFU.

CONCLUSION

These results provide an important window into the influence of development on long-term outcomes for youth and raise the possibility that interventions for youth could be enhanced with a focus on habit formation.

PLAIN LANGUAGE SUMMARY

This study evaluated the effects of a psychological treatment (the Transdiagnostic Sleep and Circadian Intervention [TranS-C]), relative to a psychoeducation active control (PE) at 8 years following treatment, on sleep problems, the preference and tendency for later bedtimes and health risk (ie, risk for worse health). Across both groups combined, the study also examined whether more sleep health behaviors are related to better sleep and whether better sleep is related to lower health risk. At long-term follow-up, there were no differences between TranS-C and PE on any outcome. However, overall poorer sleep was related to greater health risk, and those who engaged in better sleep habits tended to have an earlier "feeling best" sleep rhythm at long-term follow-up. Given evidence that youth tend to outgrow their preference and tendency for later bedtimes with age, our findings shed light on the potential impact of development on long-term outcomes for youth and raise the question of whether treatments for youth could be improved with evidence-based tools for promoting habit formation of positive sleep behaviors.

Effectiveness of Mental Health Treatment Interventions for At-Risk Youth Within the Minnesota Runaway Intervention Program

ABSTRACT

The Runaway Intervention Program (RIP) is a strengths-based, nurse-led home visitation and case management model for runaway youth at risk of sexual exploitation, violence, and mental health challenges. RIP aims to promote healthy development, reduce trauma responses, and lower risk behaviors. This study evaluates the effectiveness of three optional psychological interventions-individual therapy, group therapy, and combined therapy-administered by licensed mental health practitioners. Using archival data from 128 RIP participants enrolled between 2015 and 2019, the study assessed pretreatment and posttreatment posttraumatic stress disorder (PTSD) symptoms using the University of California Post t raumatic Stress Disorder Index.Statistical analysis suggested a reduction in PTSD symptoms from pretreatment ( M = 35.33, SD = 15.29) to posttreatment ( M = 22.91, SD = 16.31), regardless of treatment type. There was no significant difference in symptom reduction between the three treatment modalities, indicating comparable effectiveness across modalities. Across all treatment modalities, clinically significant change analysis showed that 41% of participants recovered, 51% showed no change, 2% improved, and 6% deteriorated. These findings suggest that although RIP interventions effectively reduce PTSD symptoms, no single modality outperformed the others. The results underscore the value of flexible therapeutic options to address the diverse needs of runaway youth.

The moderation effect of mental health services use on the relationship between exposures to adverse childhood experiences and mental health outcomes among US adolescents

BACKGROUND

The prevailing exposure to Adverse Childhood Experiences (ACEs) among youth is associated with adolescents' mental health. However, few studies have examined whether receiving help from mental health services affects mental health outcomes among adolescents with ACEs. Therefore, this study examines the moderated effects of mental health services use on the relationship between exposures to ACEs and mental health outcomes among US adolescents.

METHODS

The sample was restricted to adolescents aged 11-17 using data from the National Health Interview Survey (NHIS) from 2019, 2021, and 2022. Multivariate logistic regressions and descriptive analyses were performed to estimate the moderation effect of mental health services use.

RESULTS

Using mental health services buffered the associations between ACEs and severe anxiety and depressive symptoms. Receiving counseling/therapy moderated the impact of ever living with an individual who had severe anxiety (Adjusted Odds Ratio, AOR: 0.58, p < .05) and depressive symptoms (AOR: 0.38, p < .01) among adolescents. Furthermore, counseling/therapy moderated the effect of ever living with an individual with a history of alcohol or drug abuse on severe depressive symptoms (AOR: 0.49, p < .05) and the effect of being a victim or witness of violence on severe anxiety symptoms (AOR: 0.45, p < .01). In addition, taking prescription medication moderated the effect of the experience of incarcerated family members on severe anxiety symptoms (AOR: 0.41, p < .05).

CONCLUSION

Our findings suggest that policy and practice need to encourage access to mental health care for vulnerable adolescents with ACEs to reduce the detrimental effect of their experiences on their mental health problems.

Cognitive behavioral program for the prevention of depression in at-risk adolescents: isolating the effects of dose

The current study estimated effects of intervention dose (attendance) of a cognitive behavioral prevention (CBP) program on depression-free days (DFDs) in adolescent offspring of parents with a history of depression. As part of secondary analyses of a multisite randomized controlled trial, we analyzed the complete intention-to-treat sample of 316 at-risk adolescents ages 13 to 17 years. Youth were randomly assigned to the CBP program plus usual care (n = 159) or to usual care alone (n = 157). The CBP program involved 8 weekly acute sessions and 6 monthly continuation sessions. Results showed that higher CBP program dose predicted more DFDs, with a key threshold of approximately 75% of a full dose in analyses employing instrumental variable methodology to control multiple channels of bias. Specifically, attending at more than 75% of acute phase sessions led to 45.3 more DFDs over the 9-month period after randomization, which accounted for over 12% of the total follow-up days. Instrument sets were informed by study variables and external data, including weather and travel burden. In contrast, conventional analysis methods failed to find a significant dose-outcome relation. Application of the instrumental variable approach, which better controls the influence of confounding, demonstrated that higher CBP program dose resulted in more DFDs.

The therapeutic alliance in blended versus face-to-face cognitive behavioral therapy for adolescents and young adults with a depressive disorder

Introduction

A depressive disorder during adolescence is a serious and disabling disorder, which has a high impact on the development of adolescents. Blended treatment, combining online and face-to-face sessions, is effective and can reduce some of the barriers for adolescents to use mental health care. There is a lack of knowledge about whether therapeutic alliance is established in blended treatment for adolescents and young adults suffering from a depressive disorder. This study examines whether the quality of the therapeutic alliance differs when cognitive behavior therapy (CBT) is delivered in combination with online intervention (b-CBT) compared to solely face-to-face (FtF-CBT) and the extent to which a stronger therapeutic alliance is associated with better treatment outcome.

Methods

A pragmatic quasi-experimental design was used. Data collected within two separate studies were combined. A total of 85 participants (80 % female), aged 13-22 (mean = 16.63, SD = 1.92) were recruited within mental health care institutions and diagnosed with a depressive disorder (using K-SADS). Assessments were done at pre-treatment (T0), after five weeks (T1), after ten weeks (T2), post-treatment (T3) and one to four weeks after treatment (T4) and included measures of depressive symptomatology (CDI-2). The therapeutic alliance was measured at T1, T2 and T3 by the TASC. t-tests for independent samples were used to test differences in therapeutic alliance rates between b-CBT and FtF-CBT at post-treatment. A linear growth model for depressive symptoms based on five time points with Latent Growth Curve Analysis (LGCA) was used to test whether the therapeutic alliance is associated with depressive symptoms.

Results

No differences in therapeutic alliance between b-CBT and FtF-CBT were found on either client-rated or therapist-rated therapeutic alliance. For both intervention groups, no significant association between the therapeutic alliance and depressive outcome was found.

Discussion

This study shows that providing part of CBT using an online environment does not have a negative impact on the therapeutic alliance. In contrast to earlier research, no association was found between the therapeutic alliance and therapy outcome in neither the b-CBT nor the FtF-CBT intervention.

Single-blinded, randomised, parallel-group, controlled trial comparing the efficacy and cost-effectiveness of therapist- and self-guided internet-delivered behavioural activation versus treatment as usual for adolescents with mild to moderate depression: study protocol

INTRODUCTION

The number of adolescents seeking professional help for depression is increasing and, despite advances in treatment, large unmet treatment needs remain. In the current protocol, we describe the design and methodology of a randomised controlled trial (RCT) to evaluate the clinical efficacy of two forms of internet-delivered behavioural activation (I-BA), with and without therapist support, in reducing depressive symptoms, compared with treatment as usual (TAU). Secondary objectives include examining the 12-month maintenance of the treatment effects and conducting a health economic evaluation of the interventions.

METHODS AND ANALYSIS

In this single-blinded RCT, we aim to include 215 participants aged 13-17 years with mild to moderate depression who will be randomised (1:1:1 ratio) to 10 weeks of either therapist-guided or self-guided I-BA, or TAU provided by regular mental health clinics. Data will be collected at baseline, weekly for the initial 10 weeks, post-treatment and at 3 and 12-month follow-ups. The primary endpoint is the 3-month follow-up. The primary outcome is blinded clinician-rated severity of depressive symptoms, measured by the Children's Depression Rating Scale-Revised. Treatment response is defined as a score of 'Much improved' or 'Very much improved' on the Clinical Global Impression-Improvement Scale, administered at the primary endpoint. Outcome assessors will be blinded to treatment conditions at all assessment points. A health economic evaluation of I-BA will be performed, both in the short term (primary endpoint) and the long term (12-month follow-up).

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Swedish Ethical Review Authority in June 2021. The final participant was enrolled on 3 May 2024 and expected to reach the primary endpoint by November 2024. The results of this study will be disseminated through publication in peer-reviewed journals, presented at conferences and communicated to healthcare providers and the public.

Testing the Impacts of Rational-Emotive Couple Intervention in a Sample of Parents Seeking Divorce

Marital burnout has not been extensively studied despite its huge consequences on family wellbeing and quality of family life. This study, using randomised-controlled trial, tested the impact of rational-emotive couple intervention on marital burnout in a sample of parents seeking a divorce. A total of 67 parents who participated during the rational-emotive couple intervention (RECI) were assessed using the marital burnout scale, Beck depression inventory, and parent rational and irrational beliefs scale. Crosstabulation, multivariate test analysis, and bivariate analysis were used to analyse the data collected. Results show a significant reduction of marital burnout in RECI group participants, and significant improvement was maintained at the follow-up stage. The result of the group and gender interaction effect shows no significant interaction effect of group and gender on participants' marital burnout at Time two and Time 3, respectively. The results indicate that a decrease in parents' irrational beliefs accounts for marital burnout among couples seeking a divorce. Marital burnout is positively associated with depression among couples seeking a divorce. This study concludes that the RECI is an effective intervention that reduces marital burnout which is a direct consequence of irrational beliefs which later metamorphose into depressive symptoms.

Improving usual care outcomes in major depression in youth by targeting memory specificity: A randomized controlled trial of adjunct computerized memory specificity training (c-MeST)

OBJECTIVE

Extending on previous findings that computerized Memory Specificity Training (c-MeST) improves memory specificity and depressive symptoms in Major Depressive Disorder (MDD) in adults, this study aimed to assess the effects of c-MeST in youth with MDD on memory specificity and depression in addition to other treatment.

METHODS

Participants aged 15-25 (N = 359, 76 % female; M age = 19.2, SD = 3.1), receiving predominantly psychological therapy or counseling (85 %) and/or antidepressants (52 %) were randomized to usual care and c-MeST or usual care. Cognitive and clinical outcomes were assessed at baseline and at one, three, and six-month follow-ups.

RESULTS

The usual care and c-MeST group reported higher memory specificity at one-month (d = 0.42, p = .022), but not at three or six months (d's < 0.15, p's > 0.05). The rate of MDE was numerically lower in the c-MeST group at each follow-up time-point, but group was not a statistically significant predictor at one month (64 % usual care and c-MeST vs. 68 % usual care, OR = 0.81, p = .606), three months (67 % usual care and c-MeST vs. 72 % usual care, OR = 0.64, p = .327) or six months (55 % usual care and c-MeST vs. 68 % usual care, OR = 0.56, p = .266). The usual care and c-MeST group did report lower depressive symptoms at one month (d = 0.42, p = .023) and six-months (d = 0.84, p = .001), but not three-months (d = 0.13, p > .05).

CONCLUSIONS

c-MeST may reduce symptoms in youth with MDD when provided alongside other treatments. However, there are significant limitations to this inference, including high attrition in the study and a need for more data on the acceptability of the intervention.

Cognitive and interpersonal moderators of two evidence-based depression prevention programs

OBJECTIVE

To test potential cognitive and interpersonal moderators of two evidence-based youth depression prevention programs.

METHOD

Two hundred four adolescents (Mage = 14.62 years, SD = 1.65; 56% female; 71% White, 11% Black, 11% multiracial, 5% Asian, 2% other races, 18% Hispanic/Latinx) were randomized to either a cognitive-behavioral (Coping With Stress [CWS]) or interpersonal (Interpersonal Psychotherapy-Adolescent Skills Training [IPT-AST]) prevention program. Potential moderators, selected based on theory and research, included rumination, negative cognitive style, dysfunctional attitudes, hopelessness, parent-adolescent conflict, negative interactions with parents and friends, and social support from parents and friends. Depression symptoms were assessed repeatedly through 18 months postintervention.

RESULTS

After adjusting for multiple comparisons, rumination (B = -2.02, SE = .61, p = .001, d = .47), hopelessness (B = -2.03, SE = .72, p = .005, d = .41), and conflict with father (B = 1.68, SE = .74, p = .02, d = .32) moderated intervention effects on change in depression symptoms from postintervention through 18-month follow-up. For example, at high levels of conflict with father, youth in IPT-AST reported a significant decrease in symptoms during follow-up, whereas youth in CWS reported a nonsignificant change in symptoms. At low levels of conflict with father, youth in IPT-AST reported a significant increase in symptoms during follow-up, whereas youth in CWS reported a nonsignificant change in symptoms.

CONCLUSIONS

These exploratory secondary analyses of Personalized Depression Prevention study data highlight specific cognitive and interpersonal risk factors that could be considered when determining which prevention program may be most effective for a given adolescent.

The effect of behavioral activation play therapy in adolescents with depression: A study protocol for a randomized controlled trial

BACKGROUND

Depression is a common psychological problem in adolescents worldwide. Although the World Health Organization recommends that members of this population engage in physical activity to reduce depressive symptoms, compliance with this recommendation is often low. Furthermore, although behavioral activation (BA) is recommended as a treatment for adolescents with depression, the reported effect size is small. Compared with traditional exercises, gamified physical activity (GPA) can be particularly appealing to adolescents because it is perceived as an enjoyable experience. In this study, we integrated BA and GPA to create behavioral activation play therapy (BAPT). We designed a clinical trial to investigate the feasibility, acceptability, and effectiveness of this treatment in adolescents with depression.

METHODS

This study is a randomized controlled trial (RCT) with a three-arm, assessor-blinded design, conducted to validate the effectiveness and applicability of BAPT for treating adolescent with depression. We will recruit 258 participants and randomly assign them to a BAPT group, BA group, or GPA group using a ratio of 1:1:1. Based on conventional strategies for treatment and care, the three groups will receive nine BAPT sessions, nine BA sessions, or nine GPA sessions, respectively. We will compare the outcomes of the BAPT with those of the BA and GPA interventions.

DISCUSSION

This is the first RCT to explore the effectiveness and applicability of BAPT in adolescents with depression. This study will provide evidence that may help to decrease depressive symptoms in adolescents, and will demonstrate the treatment effectiveness in terms of increasing levels of physical activity, reducing the rate of non-suicidal self-injury behaviors, and improving sleep quality. We will also assess the presence of side effects and the treatment adherence of patients receiving BAPT.

Effects of a Serious Game for Adolescent Mental Health on Cognitive Vulnerability: Pilot Usability Study

Background

Adolescent mental health is of utmost importance. E-mental health interventions, and serious games in particular, are appealing to adolescents and can have beneficial effects on their mental health. A serious game aimed at improving cognitive vulnerability (ie, beliefs or attitudes), which can predispose an individual to mental health problems, can contribute to the prevention of these problems in adolescents.

Objective

This study aimed to assess the feasibility of the prototype of a serious game called "Silver."

Methods

The prototype of the serious game was developed using a user-centered participatory design. The prototype of Silver focused on 1 aspect of a serious game for improving cognitive vulnerability in adolescents, that is, the recognition and identification of cognitive distortions. Through the game, players were required to identify and classify the character's thoughts as helpful or unhelpful. Upon successful advancement to the next level, the task becomes more challenging, as players must also identify specific types of cognitive distortions. A pre- and posttest uncontrolled design was used to evaluate the game, with a 1-week intervention phase in which participants were asked to play the game. Participants aged 12-16 years were recruited in schools. The outcomes of interest were the recognition of cognitive distortions and presence of participants' cognitive distortions. The game was also evaluated on its effects, content, and usefulness.

Results

A total of 630 adolescents played Silver and completed the assessments. Adolescents were significantly better at recognizing cognitive distortions at the pretest (mean 13.09, SD 4.08) compared to the posttest (mean 13.82, SD 5.09; t629=-4.00, P<.001). Furthermore, their cognitive distortions decreased significantly at the posttest (mean 38.73, SD 12.79) compared to the pretest (mean 41.43, SD 10.90; t629=7.98, P<.001). Participants also indicated that the game helped them recognize cognitive distortions. Many participants considered the game appealing (294/610, 48.2%) but boring (317/610, 52%) and preferred a more comprehensive game (299/610, 49%).

Conclusions

Findings from this study suggest that a serious game may be an effective tool for improving cognitive vulnerability in adolescents. The development of such a serious game, based on the prototype, is recommended. It may be an important and innovative tool for the universal prevention of mental health problems in adolescents. Future research on the effects of the game is warranted.

Delta-Beta Coupling in Adolescents with Depression: A Preliminary Examination of Associations with Age, Symptoms, and Treatment Outcomes

Cognitive behavioral therapy (CBT) is effective in treating adolescent depressive symptoms but with variable treatment response. Heterogeneity in treatment outcome may be due in part to individual differences in cognitive and emotional processes in depressed adolescents, and there is a need to identify biomarkers associated with symptoms and treatment outcomes. There has been growing interest in leveraging electroencephalography (EEG) data to examine correspondence between multiple frequency bands, and delta-beta coupling in particular is thought to underlie emotion regulation and offers a promising biomarker in adolescent depression. In the present study, clinically depressed adolescents aged 14-18 years old (N=54) completed 6-minutes of EEG at rest before and after a 16-session group CBT program. Analyses were focused on associations of pre- and post-treatment delta-beta coupling power with age, depressive symptoms and clinician-rated severity at baseline and the end of treatment, and clinician-rated improvement. Results indicated that older adolescents showed lower delta-beta coupling than younger adolescents and girls showed higher coupling post-treatment. Greater delta-beta coupling before and after treatment was associated with greater clinician-rated severity. Surprisingly, greater pre-treatment delta-beta coupling was associated with lower self-reported depressive symptoms with treatment. These results suggest that elevated delta-beta coupling, potentially reflecting more difficulty regulating emotions, is associated with gender and age in adolescents with depression and may be related to greater severity and poorer treatment outcomes, but replication in larger samples is needed.

Effectiveness of applied and casual games for young people's mental health: A systematic review of randomised controlled studies

Many youth experience mental health problems and digital games hold potential as mental health interventions. This systematic review provides an overview of randomised controlled studies assessing the effectiveness of digital applied and casual games for improving mental health in youth aged 6-24 years. A systematic search of PsycINFO, Web of Science and Pubmed yielded 145 eligible studies. Studies on (sub)clinical participant samples (n = 75) most often focused on attention-deficit/hyperactivity disorder (ADHD), autism and anxiety. Applied games were found most effective for improving social skills, verbal memory and anxiety, whereas casual games were found most effective for improving depression, anxiety and ADHD. Studies involving healthy youth (n = 70) were grouped into papers examining anxiety in medical settings, momentary effects on positive and negative affect, and papers employing a longitudinal design measuring mental health trait outcomes. Promising results were found for the use of games as distraction tools in medical settings, and for applied and casual games for improving momentary affect. Overall, our findings demonstrate the potential of digital games for improving mental health. Implications and recommendations for future research are discussed, such as developing evaluation guidelines, clearly defining applied games, harmonising outcome measures, including positive outcomes, and examining nonspecific factors that may influence symptom improvement as well.

In Context: Lessons About Adolescent Unipolar Depression From the Improving Mood With Psychoanalytic and Cognitive Therapies Trial

This paper summarizes the results of the Improving Mood with Psychoanalytic and Cognitive Therapies (IMPACT) study and its implications for psychological treatment of adolescents with moderate to severe unipolar major depression. IMPACT was a pragmatic, superiority, randomized controlled trial conducted in the United Kingdom, which compared the clinical and cost-effectiveness of short-term psychoanalytic therapy (STPP), cognitive-behavioral therapy (CBT), and a brief psychosocial intervention (BPI) in reducing depression symptoms in 465 adolescents with unipolar major depression, aged 11 to 17 years. Although this was a clinically heterogeneous group of adolescents, some symptoms (eg, sleep and concentration difficulties, irritability/anger) were common and disabling. The trial reported no significant difference among the 3 treatments in reducing depression symptoms. One year after treatment, 84% of participants showed improvement in depressive symptoms (<50% of baseline symptoms) and improved psychosocial functioning, achieving this through different symptom reduction trajectories. Although participants attended fewer treatment sessions than planned, the 3 treatments were delivered with fidelity to their respective models. Ending treatment without therapist agreement occurred in 37% of cases. This was not associated with outcomes by treatment group. Adolescents emphasized the importance of the therapeutic relationship in all 3 treatments. Results suggest that although most adolescents respond to time-limited, structured psychological therapy, subgroups of depressed adolescents are likely to need additional treatment or support. These include adolescents who live in complex circumstances and/or who believe that their needs are not met in therapy, some who stop treatment early, and the 16% to 18% of adolescents who do not respond to treatment.

Family-Based Interventions for Youth Depression: Meta-Analysis of Randomized Clinical Trials

Youth depression is an impairing pediatric condition for which psychotherapy effects are modest. Can outcomes be improved by treatments that address the family context, as proposed in practice parameters of the American Academy of Child and Adolescent Psychiatry? To find out, we searched five decades of research for randomized controlled trials testing family-based interventions; 11 trials were found for ages 4-18 years. Using robust variance estimation, we obtained estimates of effect size (ES) and tested candidate moderators that might explain variation in ES. Overall pooled ES of the studies was 0.33 at posttreatment, similar to that reported for all youth depression treatments in three prior meta-analyses (i.e., 0.36, 0.30, and 0.29), but higher for adolescents (ages ≥ 13, 0.50) than children (0.04). Taken together, our findings do not show superior outcomes for family-based interventions, and raise questions about how much confidence can be placed in the evidence base to date. The small number of relevant studies in more than five decades, together with the publication bias and risk of bias concerns, highlights the need for more trials testing family-based treatment, and for pre-registered reports, publicly-available preprints, and other mechanisms for improving the dissemination of completed research.

Research Review: The internalizing paradox - youth anxiety and depression symptoms, psychotherapy outcomes, and implications for research and practice

BACKGROUND

Youth anxiety and depression have long been combined within the empirically derived internalizing syndrome. The two conditions show substantial comorbidity, symptom co-occurrence, and overlap in treatment procedures, but paradoxically diverge in psychotherapy outcomes: strong, positive effects for anxiety and weak effects for depression.

METHODS

Drawing on recent research, we examine candidate explanations for this paradox to help identify strategies for addressing it by improving outcomes for youth depression.

RESULTS

Candidate explanations include that youth depression, compared with youth anxiety, has more varied comorbidities and more heterogeneous symptom combinations, has greater uncertainty regarding mediators and mechanisms of change, is treated with more complex and potentially confusing protocols, and has characteristics that may impede client engagement. Candidate strategies for shrinking the psychotherapy effectiveness gap include personalizing through transdiagnostic modular treatment, simplifying therapy by focusing on empirically supported principles of change, developing effective strategies for engaging family members as intervention allies, using shared decision-making to inform clinical decisions and boost client engagement, capitalizing on youth-friendly technological advances, and shortening and digitizing treatments to enhance their accessibility and appeal.

CONCLUSIONS

Recent advances suggest explanations for the internalizing paradox, which in turn suggest strategies for shrinking the youth anxiety-depression psychotherapy outcome gap; these form an agenda for a promising new era of research.

Differential sensitivity to adversity by income: Evidence from a study of Bereavement

Adverse life events are often understood as having negative consequences for mental health via objective hardships, which are worse for persons with less income. But adversity can also affect mental health via more subjective mechanisms, and here, it is possible that persons with higher income will exhibit greater psychological sensitivity to negative events, for various reasons. Drawing on multiple sociological literatures, this article theorizes potential mechanisms of increasing sensitivity with income. The proposition of differential sensitivity is tested using the strategic case of spousal and parental bereavement among older US adults. The analyses find consistent evidence of increasing sensitivity of depressive symptoms with income. A series of robustness checks indicate that findings are not due to endogenous or antecedent selection. Further, exploratory analyses of mechanisms suggest that higher sensitivity among the affluent was driven by greater expectations and better relationship quality with the deceased. These findings problematize the conceptualization and assessment of human suffering in economically stratified societies.

Do relationship education programs reduce relationship aggression? A meta-analytic study

There is an increasing focus on evaluating the effectiveness of Relationship Education (RE) programs on reducing relationship aggression. Nevertheless, there has been little by way of a systematic quantitative synthesis of research to date. The primary aim of this research was to conduct a meta-analysis into the effects of RE programs on relationship aggression and provide a comprehensive assessment as to the moderating effects of various methodological characteristics of studies. A secondary aim was to determine whether RE programs reduce negative aspects of relationship functioning that are known to exacerbate relationship aggression. Thirty-one studies (n = 25,527) were included comprising of pre-post comparison studies and control trials. Overall, RE programs were significantly associated with reductions in relationship aggression (d = 0.11, p = .001). Pre-post studies yielded a significantly larger effect size (d = 0.28, p < .001) than RCT studies (d = 0.05, p = .10). Subgroup analysis revealed that participants who reported moderate to severe relationship aggression upon RE program entry demonstrated large reductions in physical (d = 0.66, p = .01) and psychological (d = 0.85, p < .001) aggression compared to those who reported minimal to low relationship aggression on entry (physical aggression d = 0.07, p = .009; psychological aggression d = -0.04; p = .17). Amongst participants who reported moderate to severe relationship aggression, RE programs were also found to reduce controlling behavior (d = 0.20, p < .01) and conflict behavior (d = 0.40, p < .001). Findings demonstrate the emerging efficacy of RE programs for reducing relationship aggression and conflict behavior, particularly in those with a history of moderate to severe levels of relationship aggression.

Adjunctive repetitive transcranial magnetic stimulation for adolescents with first-episode major depressive disorder: a meta-analysis

OBJECTIVE

This meta-analysis of randomized clinical trials (RCTs) was conducted to explore the therapeutic effects, tolerability and safety of repetitive transcranial magnetic stimulation (rTMS) as an adjunct treatment in adolescents with first-episode major depressive disorder (FE-MDD).

METHODS

RCTs examining the efficacy, tolerability and safety of adjunctive rTMS for adolescents with FE-MDD were included. Data were extracted by three independent authors and synthesized using RevMan 5.3 software with a random effects model.

RESULTS

A total of six RCTs involving 562 adolescents with FE-MDD were included. Adjunctive rTMS was superior in improving depressive symptoms over the control group [standardized mean difference (SMD) = -1.50, 95% confidence interval (CI): -2.16, -0.84; I2 = 89%, p < 0.00001] in adolescents with FE-MDD. A sensitivity analysis and two subgroup analyses also confirmed the significant findings. Adolescents with FE-MDD treated with rTMS had significantly greater response [risk ratio (RR) = 1.35, 95% CI: 1.04, 1.76; I2 = 56%, p = 0.03] and remission (RR = 1.35, 95% CI: 1.03, 1.77; I2 = 0%, p = 0.03) over the control group. All-cause discontinuations were similar between the two groups (RR = 0.79, 95% CI: 0.32, 1.93; I2 = 0%, p = 0.60). No significant differences were found regarding adverse events, including headache, loss of appetite, dizziness and nausea (p = 0.14-0.82). Four out of six RCTs (66.7%), showed that adjunctive rTMS was more efficacious over the control group in improving neurocognitive function (all p < 0.05).

CONCLUSION

Adjunctive rTMS appears to be a beneficial strategy in improving depressive symptoms and neurocognitive function in adolescents with FE-MDD. Higher quality RCTs with larger sample sizes and longer follow-up periods are warranted in the future.

A multi-site pilot randomized clinical trial of the Treatment and Education Approach for Childhood-onset Lupus (TEACH) program: study design and COVID-19 adaptations

BACKGROUND

Childhood-onset Systemic Lupus Erythematosus (cSLE) is an autoimmune disease associated with fatigue, mood symptoms, and pain. Fortunately, these symptoms are potentially modifiable with psychological intervention such as cognitive-behavioral therapy (CBT). The Treatment and Education Approach for Childhood-onset Lupus (TEACH) program is a CBT intervention developed to target these symptoms for adolescents and young adults with cSLE. This pilot randomized controlled trial (RCT) aims to determine the feasibility and effect of TEACH for youth with cSLE. Adjustments to the study protocol following the COVID-19 pandemic are also described.

METHODS

This two-arm multisite RCT will explore the feasibility (primary outcome) and effect (secondary outcome) of a remotely delivered TEACH protocol. Participants will be randomized to a six-week remotely delivered TEACH program plus medical treatment as usual (TAU) or TAU alone. We will include patients ages 12-22 years presenting to rheumatology clinics from six sites. Validated measures of fatigue, depressive symptoms, and pain will be obtained at baseline and approximately eight and 20 weeks later. Protocol adjustments were also made due to the COVID-19 pandemic, in collaboration with the investigative team, which included patients and caregivers.

CONCLUSIONS

Findings from this multi-site RCT aim to document the feasibility of TEACH and provide an estimate of effect of a remotely delivered TEACH protocol on fatigue, depression, and pain symptoms in youth with cSLE as compared to standard medical treatment alone. This findings may positively impact clinical care for patients with cSLE.

Social Support and Parental Conflict as Predictors of Outcomes of Group Cognitive Behavioral Therapy for Adolescent Depression

Group cognitive behavioral therapy (CBT) is an effective treatment for adolescent depression, but outcomes vary. Our goal was to examine interpersonal factors that predict response to group CBT for adolescent depression using a broad range of outcomes, including depressive symptoms, session attendance, treatment completion, engagement, and improvement. Seventy adolescents (age 14-18) with depression completed self-report measures of social support and parental conflict and were offered an established 16-session group CBT program. Correlation and regression analyses were conducted for interpersonal predictors and CBT outcomes. Accounting for pre-treatment depressive symptoms, fewer social supports predicted lower likelihood of finishing treatment and less clinician-rated improvement. Greater pre-treatment parental conflict predicted fewer sessions attended, lower clinician-rated engagement, and less clinician-rated improvement. Results highlight the need to consider interpersonal difficulties in CBT, as they may present a barrier to treatment attendance, engagement, and improvement.

Eye movement desensitization and processing for adolescents with major depressive disorder: study protocol for a multi-site randomized controlled trial

BACKGROUND

Major depressive disorder (MDD) is one of the most common mental disorders in adolescence carrying a serious risk of adverse development later in life. Extant treatments are limited in effectiveness and have high drop-out and relapse rates. A body of literature has been published on the association between distressing/ traumatic experiences and development and maintenance of MDD, but the effectiveness of a trauma-focused treatment approach for MDD has hardly been studied. This study aims to determine the effectiveness of eye movement desensitization and reprocessing (EMDR) therapy as stand-alone intervention in adolescents diagnosed with MDD.

METHODS

This study will be a randomized controlled trial with two conditions: (1) EMDR treatment (6 sessions) and (2) waiting list condition (WL: 6 weeks, followed by EMDR treatment). First, participants receive a baseline measure after which they will be randomized. Participants will be assessed post-intervention after which the WL participants will also receive six EMDR sessions. Follow-up assessments will be conducted at 3 and 6 months follow-up.

STUDY POPULATION

In total, 64 adolescents (aged 12-18) diagnosed with a major depressive disorder (DSM-5) and identified memories of at least one distressing or traumatic event related to the depressive symptomatology will be included. Main study parameters/endpoints: Primary outcome variables will be the percentage of patients meeting criteria for MDD classification, and level of depressive symptoms. Secondary outcome measures include symptoms of PTSD, anxiety, and general social-emotional problems. At baseline, family functioning and having experienced emotional abuse or neglect will be assessed to explore whether these factors predict post-treatment outcome.

DISCUSSION

With the present study, we aim to investigate whether EMDR as a trauma-focussed brief intervention may be effective for adolescents with a primary diagnosis of MDD. EMDR has been proven an effective treatment for traumatic memories in other disorders. It is hypothesized that traumatic memories play a role in the onset and maintenance of depressive disorders. Particularly in adolescence, early treatment of these traumatic memories is warranted to prevent a more chronic or recurrent course of the disorder.

The Operations Triad Model and Youth Mental Health Assessments: Catalyzing a Paradigm Shift in Measurement Validation

Researchers strategically assess youth mental health by soliciting reports from multiple informants. Typically, these informants (e.g., parents, teachers, youth themselves) vary in the social contexts where they observe youth. Decades of research reveal that the most common data conditions produced with this approach consist of discrepancies across informants' reports (i.e., informant discrepancies). Researchers should arguably treat these informant discrepancies as domain-relevant information: data relevant to understanding youth mental health domains (e.g., anxiety, depression, aggression). Yet, historically, in youth mental health research as in many other research areas, one set of paradigms has guided interpretations of informant discrepancies: Converging Operations and the Multi-Trait Multi-Method Matrix (MTMM). These paradigms (a) emphasize shared or common variance observed in multivariate data, and (b) inspire research practices that treat unique variance (i.e., informant discrepancies) as measurement confounds, namely random error and/or rater biases. Several yearsw ago, the Operations Triad Model emerged to address a conceptual problem that Converging Operations does not address: Some informant discrepancies might reflect measurement confounds, whereas others reflect domain-relevant information. However, addressing this problem requires more than a conceptual paradigm shift beyond Converging Operations. This problem necessitates a paradigm shift in measurement validation. We advance a paradigm (Classifying Observations Necessitates Theory, Epistemology, and Testing [CONTEXT]) that addresses problems with using the MTMM in youth mental health research. CONTEXT optimizes measurement validity by guiding researchers to leverage (a) informants that produce domain-relevant informant discrepancies, (b) analytic procedures that retain domain-relevant informant discrepancies, and (c) study designs that facilitate detecting domain-relevant informant discrepancies.

Biased Maintenance of Attention on Sad Faces in Clinically Depressed Youth: An Eye-Tracking Study

The role of negative attention biases (AB), central to cognitive models of adult depression, is yet unclear in youth depression. We investigated negative AB in depressed compared to healthy youth and tested whether AB are more pronounced in depressed than at-risk youth. Negative AB was assessed for sad and angry faces with an eye-tracking paradigm [Passive Viewing Task (PVT)] and a behavioural task [Visual Search Task (VST)], comparing three groups of 9-14-year-olds: youth with major depression (MD; n = 32), youth with depressed parents (high-risk; HR; n = 49) and youth with healthy parents (low-risk; LR; n = 42). The PVT revealed MD participants to maintain attention longer on sad faces compared to HR, but not LR participants. This AB correlated positively with depressive symptoms. The VST revealed no group differences. Our results provide preliminary evidence for a negative AB in maintenance of attention on disorder-specific emotional information in depressed compared to at-risk youth.

Introduction to the Special Issue. A Dozen Years of Demonstrating That Informant Discrepancies are More Than Measurement Error: Toward Guidelines for Integrating Data from Multi-Informant Assessments of Youth Mental Health

Validly characterizing youth mental health phenomena requires evidence-based approaches to assessment. An evidence-based assessment cannot rely on a "gold standard" instrument but rather, batteries of instruments. These batteries include multiple modalities of instrumentation (e.g., surveys, interviews, performance-based tasks, physiological readings, structured clinical observations). Among these instruments are those that require soliciting reports from multiple informants: People who provide psychometrically sound data about youth mental health (e.g., parents, teachers, youth themselves). The January 2011 issue of the Journal of Clinical Child and Adolescent Psychology (JCCAP) included a Special Section devoted to the most common outcome of multi-informant assessments of youth mental health, namely discrepancies across informants' reports (i.e., informant discrepancies). The 2011 JCCAP Special Section revolved around a critical question: Might informant discrepancies contain data relevant to understanding youth mental health (i.e., domain-relevant information)? This Special Issue is a "sequel" to the 2011 Special Section. Since 2011, an accumulating body of work indicates that informant discrepancies often contain domain-relevant information. Ultimately, we designed this Special Issue to lay the conceptual, methodological, and empirical foundations of guidelines for integrating multi-informant data when informant discrepancies contain domain-relevant information. In this introduction to the Special Issue, we briefly review the last 12 years of research and theory on informant discrepancies. This review highlights limitations inherent to the most commonly used strategies for integrating multi-informant data in youth mental health. We also describe contributions to the Special Issue, including articles about informant discrepancies that traverse multiple content areas (e.g., autism, implementation science, measurement validation, suicide).

Adaptation of Adolescent Behavioral Activation Program and Investigation of Its Effectiveness by Mixed Method

In this study, the Adolescent Behavioral Activation Program (A-BAP) based on behavioral activation (BA) therapy to reduce depressive symptoms in adolescents was adapted to Turkish culture, and its effectiveness was tested with intervention design, one of the mixed method designs. In this direction, experimental and control groups were formed with 20 students studying in three different high schools in Turkey and with highly elevated depressive symptoms. The study group was determined by nested sampling from mixed-method sampling strategies. The starting point of this study is the absence of any BA-based practice to reduce adolescent depression in Turkey. In this direction, experimental and control groups were formed with 20 students studying in three different high schools in Turkey and with highly elevated depressive symptoms. The adapted A-BAP was applied individually to the students in the experimental group for 12 weeks. Three sessions were also held with the parents of the students in the experimental group. In the quantitative phase of the study, pre-test and post-test control groups paired patterns from semi-experimental designs, and a case study was used in the qualitative stage. The qualitative data of the study were collected from adolescents and their parents through semi-structured interviews and session evaluation forms. It was determined that the adapted BA-based A-BAP was an effective intervention in reducing depressive symptoms in the Turkish adolescent sample and provided a significant decrease in the depression scores of the participants in the experimental group . The qualitative findings show that adolescents perceive the A-BAP process as a factor contributing to making them feel better. Adolescents have reported that A-BAP is effective in reducing avoidance behavior, achieving anger control, and increasing self-esteem and social interaction. Parents consider A-BAP as a developer, educator, and practice that reduces depressive symptoms in their children. In addition, it was determined that the qualitative findings obtained supported the quantitative results. Since the study is the first application of BA therapy in Turkey, it is thought that it will contribute to new studies in Turkey and intercultural studies at the international level.

Therapist-guided and self-guided internet-delivered behavioural activation for adolescents with depression: a randomised feasibility trial

OBJECTIVE

Access to effective treatments for adolescents with depression needs to improve. Few studies have evaluated behavioural activation (BA) for adolescent depression, and none remotely delivered BA. This study explored the feasibility and acceptability of therapist-guided and self-guided internet-delivered BA (I-BA) in preparation for a future randomised controlled trial (RCT).

DESIGN

A single-blinded randomised controlled feasibility trial.

SETTING

A specialist outpatient clinic in Sweden.

PARTICIPANTS

Thirty-two adolescents with mild-to-moderate major depression, aged 13-17 years.

INTERVENTIONS

Ten weeks of therapist-guided I-BA or self-guided I-BA, or treatment as usual (TAU). Both versions of I-BA included parental support. TAU included referral to usual care within child and youth psychiatry or primary care.

OUTCOMES

Feasibility measures included study take-up, participant retention, acceptability, safety and satisfaction. The primary outcome measure was the blinded assessor-rated Children's Depression Rating Scale, Revised. The primary endpoint was the 3-month follow-up.

RESULTS

154 adolescents were screened and 32 were randomised to therapist-guided I-BA (n=11), self-guided I-BA (n=10) or TAU (n=11). Participant retention was acceptable, with two drop-outs in TAU. Most participants in TAU had been offered interventions by the primary endpoint. The mean number of completed chapters (total of 8) for adolescents was 7.5 in therapist-guided I-BA and 5.4 in self-guided I-BA. No serious adverse events were recorded. Satisfaction was acceptable in both I-BA groups. Following an intent-to-treat approach, the linear mixed-effects model revealed that both therapist-guided and self-guided I-BA (Cohen's d=2.43 and 2.23, respectively), but not TAU (Cohen's d=0.95), showed statistically significant changes on the primary outcome measure with large within-group effect sizes.

CONCLUSIONS

Both therapist-guided and self-guided I-BA are acceptable and potentially efficacious treatments for adolescents with depression. It is feasible to conduct a large-scale RCT to establish the efficacy and cost-effectiveness of I-BA versus TAU.

Predictors of outcome after a time-limited psychosocial intervention for adolescent depression

Research on the predictors of outcome for early, community-based, and time-limited interventions targeted for clinical depression in adolescents is still scarce. We examined the role of demographic, psychosocial, and clinical variables as predictors of outcome in a trial conducted in Finnish school health and welfare services to identify factors associating to symptom reduction and remission after a brief depression treatment. A total of 55 12-16-year-olds with mild to moderate depression received six sessions of either interpersonal counseling for adolescents (IPC-A) or brief psychosocial support (BPS). Both interventions resulted in clinical improvement at end of treatment and 3- and 6-month follow-ups. Main outcome measures were self-rated BDI-21 and clinician-rated Adolescent Depression Rating Scale (ADRSc). Latent change score (LCS) models were used to identify predictors of change in depressive symptom scores and clinical remission at end of treatment and 3- and 6-month follow-ups over the combined brief intervention group. Symptom improvement was predicted by younger age and having a close relationship with parents. Both symptom improvement and clinical remission were predicted by male gender, not having comorbid anxiety disorder, and not having sleep difficulties. Our results add to knowledge on factors associating with good treatment outcome after a brief community intervention for adolescent depression. Brief depression interventions may be useful and feasible especially for treatment of mild and moderate depression among younger adolescents and boys, on the other hand clinicians may need to cautiously examine sleep problems and anxiety comorbidity as markers of the need for longer treatment.

Acceptability and Feasibility of an Intervention to Enhance Social Group Belonging: Evidence From Three Trials of Groups 4 Health

Groups 4 Health (G4H) is a group psychotherapy program that targets social group disconnection. An emerging evidence base supports its efficacy in reducing loneliness, depression, and social anxiety. However, to date there has been no formal analysis of its acceptability to clients and therapists, nor an investigation of its feasibility for wider implementation. This input from end users is crucial to ensure the program's wider suitability and to contribute to its improvement. This study drew data from three clinical trials, including 266 G4H clients and 68 G4H therapists. From the Phase III trial only, additional data were available from 90 clients in a dose-controlled cognitive-behavioral therapy (CBT) comparison group, and focus groups/interviews with 6 therapists and 13 clients. Client satisfaction was high, with all average ratings &gt;7/10, significantly exceeding the CBT comparison group. Therapist satisfaction with each module was &gt;5/7. Retention was &gt;80%. Homework completion was high, with &lt;10% of clients saying that they had not attempted the homework. Therapists and clients both emphasized the benefits arising from G4H, and the contribution of the group context itself as a vehicle to achieve positive outcomes.

Identification and Characterization of Elevated Expression of Transferrin and Its Receptor TfR1 in Mouse Models of Depression

Depression has become one of the severe mental disorders threatening global human health. In this study, we first used the proteomics approach to obtain the differentially expressed proteins in the liver between naive control and chronic social defeat stress (CSDS) induced depressed mice. We have identified the upregulation of iron binding protein transferrin (TF) in the liver, the peripheral blood, and the brain in CSDS-exposed mice. Furthermore, bioinformatics analysis of the Gene Expression Omnibus (GEO) database from various mouse models of depression revealed the significantly upregulated transcripts of TF and its receptor TfR1 in multiple brain regions in depressed mice. We also used the recombinant TF administration via the tail vein to detect its permeability through the blood-brain barrier (BBB). We demonstrated the permeability of peripheral TF into the brain through the BBB. Together, these results identified the elevated expression of TF and its receptor TfR1 in both peripheral liver and the central brain in CSDS-induced depressed mice, and peripheral administration of TF can be transported into the brain through the BBB. Therefore, our data provide a compelling information for understanding the potential role and mechanisms of the cross-talk between the liver and the brain in stress-induced depression.

Neurostructural Differences in Adolescents With Treatment-Resistant Depression and Treatment Effects of Transcranial Magnetic Stimulation

BACKGROUND

Despite its morbidity and mortality, the neurobiology of treatment-resistant depression (TRD) in adolescents and the impact of treatment on this neurobiology is poorly understood.

METHODS

Using automatic segmentation in FreeSurfer, we examined brain magnetic resonance imaging baseline volumetric differences among healthy adolescents (n = 30), adolescents with major depressive disorder (MDD) (n = 19), and adolescents with TRD (n = 34) based on objective antidepressant treatment rating criteria. A pooled subsample of adolescents with TRD were treated with 6 weeks of active (n = 18) or sham (n = 7) 10-Hz transcranial magnetic stimulation (TMS) applied to the left dorsolateral prefrontal cortex. Ten of the adolescents treated with active TMS were part of an open-label trial. The other adolescents treated with active (n = 8) or sham (n = 7) were participants from a randomized controlled trial.

RESULTS

Adolescents with TRD and adolescents with MDD had decreased total amygdala (TRD and MDD: -5%, P = .032) and caudal anterior cingulate cortex volumes (TRD: -3%, P = .030; MDD: -.03%, P = .041) compared with healthy adolescents. Six weeks of active TMS increased total amygdala volumes (+4%, P < .001) and the volume of the stimulated left dorsolateral prefrontal cortex (+.4%, P = .026) in adolescents with TRD.

CONCLUSIONS

Amygdala volumes were reduced in this sample of adolescents with MDD and TRD. TMS may normalize this volumetric finding, raising the possibility that TMS has neurostructural frontolimbic effects in adolescents with TRD. TMS also appears to have positive effects proximal to the site of stimulation.

Conceptual, methodological, and measurement factors that disqualify use of measurement invariance techniques to detect informant discrepancies in youth mental health assessments

On page 1 of his classic text, Millsap (2011) states, "Measurement invariance is built on the notion that a measuring device should function the same way across varied conditions, so long as those varied conditions are irrelevant [emphasis added] to the attribute being measured." By construction, measurement invariance techniques require not only detecting varied conditions but also ruling out that these conditions inform our understanding of measured domains (i.e., conditions that do not contain domain-relevant information). In fact, measurement invariance techniques possess great utility when theory and research inform their application to specific, varied conditions (e.g., cultural, ethnic, or racial background of test respondents) that, if not detected, introduce measurement biases, and, thus, depress measurement validity (e.g., academic achievement and intelligence). Yet, we see emerging bodies of work where scholars have "put the cart before the horse" when it comes to measurement invariance, and they apply these techniques to varied conditions that, in fact, may reflect domain-relevant information. These bodies of work highlight a larger problem in measurement that likely cuts across many areas of scholarship. In one such area, youth mental health, researchers commonly encounter a set of conditions that nullify the use of measurement invariance, namely discrepancies between survey reports completed by multiple informants, such as parents, teachers, and youth themselves (i.e., informant discrepancies). In this paper, we provide an overview of conceptual, methodological, and measurement factors that should prevent researchers from applying measurement invariance techniques to detect informant discrepancies. Along the way, we cite evidence from the last 15 years indicating that informant discrepancies reflect domain-relevant information. We also apply this evidence to recent uses of measurement invariance techniques in youth mental health. Based on prior evidence, we highlight the implications of applying these techniques to multi-informant data, when the informant discrepancies observed within these data might reflect domain-relevant information. We close by calling for a moratorium on applying measurement invariance techniques to detect informant discrepancies in youth mental health assessments. In doing so, we describe how the state of the science would need to fundamentally "flip" to justify applying these techniques to detect informant discrepancies in this area of work.

The Impact of Mobile Technology-Delivered Interventions on Youth Well-being: Systematic Review and 3-Level Meta-analysis

BACKGROUND

Rates of mental health problems among youth are high and rising, whereas treatment seeking in this population remains low. Technology-delivered interventions (TDIs) appear to be promising avenues for broadening the reach of evidence-based interventions for youth well-being. However, to date, meta-analytic reviews on youth samples have primarily been limited to computer and internet interventions, whereas meta-analytic evidence on mobile TDIs (mTDIs), largely comprising mobile apps for smartphones and tablets, have primarily focused on adult samples.

OBJECTIVE

This study aimed to evaluate the effectiveness of mTDIs for a broad range of well-being outcomes in unselected, at-risk, and clinical samples of youth.

METHODS

The systematic review used 5 major search strategies to identify 80 studies evaluating 83 wellness- and mental health-focused mTDIs for 19,748 youth (mean age 2.93-26.25 years). We conducted a 3-level meta-analysis on the full sample and a subsample of the 38 highest-quality studies.

RESULTS

Analyses demonstrated significant benefits of mTDIs for youth both at posttest (g=0.27) and follow-up (range 1.21-43.14 weeks; g=0.26) for a variety of psychosocial outcomes, including general well-being and distress, symptoms of diverse psychological disorders, psychosocial strategies and skills, and health-related symptoms and behaviors. Effects were significantly moderated by the type of comparison group (strongest for no intervention, followed by inert placebo or information-only, and only marginal for clinical comparison) but only among the higher-quality studies. With respect to youth characteristics, neither gender nor pre-existing mental health risk level (not selected for risk, at-risk, or clinical) moderated effect sizes; however, effects increased with the age of youth in the higher-quality studies. In terms of intervention features, mTDIs in these research studies were effective regardless of whether they included various technological features (eg, tailoring, social elements, or gamification) or support features (eg, orientation, reminders, or coaching), although the use of mTDIs in a research context likely differs in important ways from their use when taken up through self-motivation, parent direction, peer suggestion, or clinician referral. Only mTDIs with a clear prescription for frequent use (ie, at least once per week) showed significant effects, although this effect was evident only in the higher-quality subsample. Moderation analyses did not detect statistically significant differences in effect sizes based on the prescribed duration of mTDI use (weeks or sessions), and reporting issues in primary studies limited the analysis of completed duration, thereby calling for improved methodology, assessment, and reporting to clarify true effects.

CONCLUSIONS

Overall, this study's findings demonstrate that youth can experience broad and durable benefits of mTDIs, delivered in a variety of ways, and suggest directions for future research and development of mTDIs for youth, particularly in more naturalistic and ecologically valid settings.

Investigating the feasibility and effectiveness of a modular treatment program for children and adolescents with depression and interpersonal problems: study protocol of a quasi-experimental pilot feasibility trial (CBASP@YoungAge)

BACKGROUND

Depression is a serious disorder in childhood and adolescence. Affected children and adolescents show significant impairments in various aspects of life. Studies on the effectiveness or efficacy of psychotherapy in depressed children and adolescents are qualitatively very heterogeneous and reveal small effect sizes. There is thus a need to better tailor psychotherapy approaches to these age groups to improve outcomes like parent-child relationship, symptomatology, or quality of life. To address this gap, we designed a modular, individualized treatment program for children and adolescents based on the Cognitive Behavioral Analysis System of Psychotherapy (CBASP) including caregiver involvement.

METHOD

This quasi-experimental pilot feasibility trial is a phase 1 to phase 2 study investigating the feasibility and effectiveness of CBASP@YoungAge by including an intervention group (CBASP@YoungAge) and a treatment-as-usual control group. The treatment of depressive symptoms as well as interpersonal problems with primary caregivers are the main targets of CBASP@YoungAge. Personalization is ensured concerning the treatment course, caregivers' involvement, and the patient's age. The primary outcome relates to two areas: the feasibility of the CBASP@YoungAge treatment program in an outpatient context and a change in patients' depressive symptomatology from before to after treatment. We conduct a brief process evaluation after each session in the intervention group to closely monitor the treatment process and examine feasibility from the therapists' and patients' perspectives and mechanisms of symptom change. In addition, we consider interpersonal behavior between children and caregivers, parenting behavior, and monitor the global-health-index in children and parents as secondary outcomes. Pre-, post-, and follow-up data are evaluated.

DISCUSSION

This is the first study of a modular-based intervention program for children and adolescents with depression and a clear focus on the interpersonal problems between the depressed young patient and her/his caregiver. It will provide important knowledge on the feasibility and effectiveness of the program and potential benefits of including caregivers in psychotherapy. Based on this study's results, we plan a multicenter, randomized, controlled trial whose long-term aim is to improve the psychotherapeutic care of young patients with depression while preventing persistent courses of depressive disorders.

Long-term effectiveness and trajectories of change after treatment with SMART, a transdiagnostic CBT for adolescents with emotional problems

Background

There is a need for long-term effectiveness trials of transdiagnostic treatments. This study investigates the effectiveness and diagnosis-specific trajectories of change in adolescent patients attending SMART, a 6-week transdiagnostic CBT for anxiety and depression, with 6-month follow-up.

Methods

A randomized controlled trial with waiting list control (WLC) was performed at three child and adolescent mental health outpatient services (CAMHS) in Norway. Referred adolescents (N = 163, age = 15.72, 90.3% females) scoring 6 or more on the emotional disorders subscale of the Strengths and Difficulties Questionnaire (SDQ) were randomly assigned to treatment or to WLC. Long-term follow-up (N = 83, baseline age = 15.57, 94% females) was performed 6 months after treatment completion (Mean = 7.1 months, SD = 2.5). Linear mixed model analysis was used to assess time by group effects in patients with no diagnosis, probable anxiety, depressive disorder, and combined anxiety and depressive disorder.

Results

Almost one third (31%) obtained full recovery according to the inclusion criterium (SDQ emotional). There was highly significant change in all outcome variables. Effect sizes (ES) were largest for general functioning, measured with CGAS (ES: d = 2.19), and on emotional problems measured with SDQ (ES: d = 2.10), while CORE-17, BDI-II and CGAS all obtained ES’s close to 1. There were no significant time by diagnostic group interactions for any outcomes, indicating similar trajectories of change, regardless of diagnostic group. Waiting 6 weeks for treatment had no significant impact on long-term treatment effects.

Limitations

Possible regression to the mean. Attrition from baseline to follow-up.

Conclusions

Six weeks of transdiagnostic treatment for adolescents with emotional problems showed highly significant change in emotional symptoms and functioning at 6-month follow-up. Patients with anxiety, depression, combined anxiety and depression, and emotional problems with no specific diagnoses, all had similar trajectories of change. Hence this transdiagnostic SMART treatment can be recommended for adolescent patients with symptoms within the broad spectrum of emotional problems.

Why is my world so dark? Effects of child physical and emotional abuse on child depression: The mediating role of self-compassion and negative automatic thoughts

BACKGROUND

The adverse effects of childhood maltreatment on the mental health of individuals have received increasing attention. However, it is unclear whether the effects of invisible emotional abuse and visible physical abuse differ on child depression and the mediating processes under this relationship.

OBJECTIVE

This study aimed to investigate whether self-compassion and negative automatic thoughts mediated the effects of physical abuse and emotional abuse on child depression and the underlying mechanistic differences.

PARTICIPANTS AND SETTING

Using a two-wave longitudinal design, a total of 946 elementary school students completed the self-report questionnaires at two-time points, including child abuse, self-compassion, negative automatic thoughts, and depression.

METHODS

This study constructed structural equation models (SEM) to examine the mediating role of self-compassion and negative automatic thoughts between emotional/physical abuse and child depression.

RESULTS

After controlling for demographic covariates, structural equation modeling (SEM) showed that only physical abuse significantly and positively predicted child depression directly (β = 0.16, p < 0.01). Emotional abuse was positively associated with child depression through self-compassion (β = 0.02, p < 0.05) and negative automatic thoughts (β = 0.02, p < 0.05), while physical abuse influenced child depression only via negative automatic thoughts (β = 0.07, p < 0.001).

CONCLUSIONS

The findings showed a strong association between emotional/physical abuse and child depression, but there were mechanistic differences under these relationships. Therefore, we also need to pay equal attention to the adverse effects of emotional abuse on children.

Youth Top Problems and Early Treatment Response to the Unified Protocols for Transdiagnostic Treatment of Emotional Disorders in Children and Adolescents

The Top Problems assessment is an idiographic measure of client concerns that may allow clinicians to identify early treatment response. Few studies have examined early response to evidence-based therapies using Top Problems. We collected weekly Top Problems ratings from 95 youth with emotional disorders who received treatment using the Unified Protocols for Transdiagnostic Treatment of Emotional Disorders in Children and Adolescents (UP-C/UP-A). We assessed Top Problems rating change from session 1 to session 4, the role of pre-treatment variables in early Top Problems rating change, and the role of early Top Problems rating change in post-treatment symptom outcomes. Top Problems ratings decreased significantly from session 1 to session 4. Younger child age and higher parent cognitive flexibility were associated with early Top Problems improvement. Controlling for pre-treatment, early Top Problems rating change did not explain the variance in post-treatment outcomes. Future research should examine Top Problems trajectories over treatment course.

Family processes: Risk, protective and treatment factors for youth at risk for suicide

Family factors have continually been identified as potential risk and protective factors for youth at risk for suicide. This paper reviews family processes that not only are associated with suicide risk, but also might be malleable enough to target in treatment. We also review family intervention components have been incorporated into most youth suicide treatments. Unfortunately research on if these family processes moderator, mediator or change as a result of treatment is limited. Recommendations for future research are offered.

Longitudinal Relationship Between Bullying Victimization and Depression Among Left-Behind Children: Roles of Negative Thoughts and Self-Compassion

Background

Left-behind children (LBC) in China have aroused widespread concern in society and the academic field because they have a high risk of psychological problems. For left-behind children, depression is the most serious problem. Bullying victimization has been evidenced as one of the most common causes of children’s depression. However, less is known about its longitudinal association and the process for how bullying victimization influences depression among left-behind children. Thus, the presentation aims to explore the mechanisms underlying by considering the roles of left-behind children’s negative thoughts and self-compassion.

Methods

The 3-wave longitudinal data were collected from a sample of 605 aged 8–11 from central China. We used the Olweus bully and victimization questionnaire, the children’s automatic thoughts scale, the depression scale, and the self-compassion scale.

Results

Bullying victimization positively predicted the depression level of left-behind children. Negative thoughts and self-compassion mediate the relationship between bullying victimization and depression. In the mechanism of bullying victimization on depression exists gender differences among left-behind children.

Conclusion

The present study suggested the association between bullying victimization and left-behind children’s depression and revealed the internal mechanism of negative thoughts and self-compassion. These findings provide a new perspective for left-behind children’s mental health education and intervention.

Is Teachers' Depression Contagious to Students? A Study Based on Classes' Hierarchical Models

Background

According to the theory of emotional contagion, emotions in one person can trigger similar emotions in groups within social networks. In schools, the class just like a small social network, that teachers' emotion, such as depression, might be contagious to their students. However, until now there is few studies reporting this issue. This study aims to explore whether teachers' depression be contagious to students and what mechanics behind the phenomenon.

Methods

Using Children's depression and cognitive scales to assess 2,579 students, meanwhile using teachers' depression and emotional labor scales assess 529 teachers. The nested data from 112 classes were analyzed.

Results

Teachers' depression was positively correlated with emotional labor surface and deep acting, and teachers' depression cross-level predicted students' depression inversely. For teachers with higher levels of depression, the teacher's deep acting affected their students' depression significantly, the more effortful the teachers' deep acting, the lower the degree of the students' depression, however, for teachers with lower levels of depression, the deep acting was not significant.

Conclusion

The results maybe state that depression in teachers is not readily transmitted to students, one of reasons is that teachers' emotional labor may alleviate the influence of their depression on students. However, considered that teachers' emotional labor was positively correlated with their depression, the teachers' emotional labor may be like a double-edged sword, while alleviating the influence of teachers' depression on students, it also deteriorated their own depression, making it impossible sustainable. For students' depression interventions based in school, including teachers maybe a better selection.

South African youth's understanding of feelings, thoughts and behaviours: Implications for the development of CBT-based mental health interventions

BACKGROUND

Mental health problems are common in youth in low- and middle-income countries (LMICs), including South Africa. Preventative interventions, based on cognitive behaviour therapy (CBT), delivered in schools, have been found to alleviate symptoms of depression and anxiety in high income countries (HICs). However, less is known about whether youth in LMICs are able to engage with the core concepts of CBT.

AIMS

To explore how young people in the Western Cape, South Africa, understand key CBT concepts, such as feelings, thoughts and behaviours.

METHOD

We interviewed 22 young people (10-15 years of age; mean age 11.6 years; SD = 1.0) recruited from two public primary schools in the Western Cape, South Africa. Interviews were audio-recorded, transcribed verbatim, translated from Afrikaans into English where necessary and analysed thematically using a deductive approach.

RESULTS

Young people described feelings as internal, private, and should only be shared with trusted others. They also described how feelings varied, depending on the situation. They found the concept of thoughts more challenging to describe. Youth were able to say what they do when they experience unpleasant feelings, and they linked their behaviours to their feelings and thoughts.

CONCLUSIONS

In this cultural context, our qualitative investigation found evidence that young people were able to engage with abstract concepts including feelings and to some degree, thoughts. To ensure that CBT-based interventions are developmentally appropriate and accessible, psychoeducation may help youth distinguish between thoughts, feelings and behaviours, and a focus on identifying and naming feelings may be beneficial.

Groups 4 Health versus cognitive-behavioural therapy for depression and loneliness in young people: randomised phase 3 non-inferiority trial with 12-month follow-up

BACKGROUND

Depression treatments are typically less effective for young people than for adults. However, treatments rarely target loneliness, which is a key risk factor in the onset, maintenance and development of depression.

AIMS

This study evaluated the efficacy of a novel loneliness intervention, Groups 4 Health (G4H), relative to the best-practice treatment of cognitive-behavioural therapy (CBT) in reducing loneliness and depression over a 12-month period (Australian New Zealand Clinical Trial Registry: ACTRN12618000440224).

METHOD

The study was a phase 3 randomised non-inferiority trial comparing G4H with dose-controlled group CBT. Participants were 174 people aged 15-25 years experiencing loneliness and clinically significant symptoms of depression, who were not in receipt of adjunct treatment. Participants were recruited from mental health services in Southeast Queensland, Australia. Randomisation was conducted using computer software. Follow-up assessments and statistical analyses were masked to allocation. Both interventions consisted of five 75 min group-based psychotherapy sessions. The primary outcomes were depression and loneliness, with a non-inferiority margin of 2.20 for depression.

RESULTS

The trial enrolled 174 participants between 24 April 2018 and 25 May 2019, with 84 in the G4H condition and 90 in the CBT condition. All randomised participants were included in the intention-to-treat analyses (n = 174). The pre-post effect sizes for depression were dG4H = -0.71 and dCBT = -0.91. For loneliness, they were dG4H = -1.07 and dCBT = -0.89. At 12-month follow-up, the absolute difference between groups on depression was 1.176 (95% CI -1.94 to 4.29) and on loneliness it was -0.679 (95% CI -1.43 to 0.07). No adverse effects were observed.

CONCLUSIONS

G4H was non-inferior to CBT for depression and showed a slight advantage over CBT for loneliness that emerged after treatment completion.

Feasibility and preliminary efficacy of a school-based health and well-being program for adolescent girls

BACKGROUND

The primary aim of this pilot study was to evaluate the feasibility and preliminary efficacy of a school-based health and well-being program (Health and Well-being for Girls: HWBG) on adolescent girls' well-being, mindfulness, screen-time, and physical activity.

METHOD

The HWBG program was evaluated using a group randomized controlled trial (RCT) in one secondary school. A convenience sample of female students in Grade 8 (mean age 14 ± 0.5 years) was recruited for the study (n=4 classes; 89 girls). The 20-week multi-component HWBG program, guided by Self-Determination Theory and Acceptance and Commitment Therapy, was designed and delivered by a member of the research team. Randomization occurred prior to baseline assessments at the class level (n=4 classes) into dose-matched treatment conditions (i.e., two classes received the HWBG intervention and two classes received an alternate elective course as a wait-list control group). Process evaluation measures of recruitment, retention, adherence, and satisfaction were used to determine program feasibility. This study was designed to assess feasibility (primary outcome) and preliminary efficacy (secondary outcomes), rather than effectiveness. Preliminary efficacy of HWBG for improving mental and social health, screen-time, and physical activity were measured and analyzed using linear mixed-models.

RESULTS

"The health and well-being program" targeting adolescent girls was found to be feasible for implementation as an elective course in a secondary school setting. Participants in the HWBG program reported high levels of satisfaction, the majority of lessons (45 out of 50), were implemented as planned and adherence to the planned HWBG program content was very high. Medium positive effects on mental health (d=0.45) and social health (d=0.50) were observed. Small effects were observed for physical activity, and no significant intervention effects were found for levels of recreational screen time. Participant ratings showed high levels of perceived benefit and enjoyment as indicated in the evaluation data (mean rating of 4.44 out of a possible 5.0) when asked whether the program was enjoyable.

CONCLUSION

The study provides preliminary support for HWBG as a potentially feasible and enjoyable program suitable for use with adolescent girls in the secondary school setting. Potential of the study for facilitating improvements in pro-social and psychological well-being is also supported.

Mental Health Therapist Perspectives on the Role of Executive Functioning in Children's Mental Health Services

Executive functioning is considered a key transdiagnostic factor underlying multiple mental health conditions. Evidence-based interventions targeting executive functioning skills exist and there are ongoing efforts to implement these interventions in routine community-based care. However, there is limited research characterizing therapist perspectives regarding addressing executive functioning within community-based mental health services. The current mixed-methods study aims to characterize mental health therapist perspectives regarding the role of executive functioning in youth clinical presentation and the psychotherapy process and outcomes as well as their experience and training related to executive functioning. Forty-three therapists completed a survey about their perspectives about executive functioning and 14 participated in subsequent focus groups to expand survey results. Results indicated that therapists perceive executive functioning challenges as impacting a large portion of children on their caseload, present across multiple mental health conditions, and that executive functioning is frequently a focus of psychotherapy. Therapists also identified executive functioning challenges as a barrier to therapy engagement and effectiveness. However, therapists reported limited knowledge and training as well as significant motivation for executive functioning training, including executive functioning interventions. Findings confirm the significant role of executive functioning in youth presenting for mental health services and the psychotherapy process and outcomes. Findings also highlight the need for further translation of evidence-based interventions and tools. Challenges as well as potential solutions to inform ongoing and future work seeking to translate and implement evidence-based executive functioning interventions in community mental health services are discussed.

Lifetime use of MDMA/ecstasy and psilocybin is associated with reduced odds of major depressive episodes

BACKGROUND

Depression is a major mental health issue worldwide, with high rates of chronicity and non-recovery associated with the condition. Existing treatments such as antidepressant medication and psychological treatments have modest effectiveness, suggesting the need for alternative interventions.

AIM

The aim of this study was to examine the relationships between MDMA (3,4-methylenedioxymethamphetamine)/ecstasy and psilocybin use and major depressive episodes (MDEs).

METHODS

This observational study used data from a large (N = 213,437) nationally representative sample of US adults to test the association of lifetime use of MDMA/ecstasy, psilocybin and other classic psychedelics (lysergic acid diethylamide (LSD), peyote, mescaline), other illegal substances (e.g. cocaine, phencyclidine (PCP)), and legal/medicinal substances of misuse (e.g. pain relievers, tranquilizers) with lifetime, past year, and past year severe MDEs.

RESULTS

Results revealed that lifetime MDMA/ecstasy use was associated with significantly lowered odds of a lifetime MDE (adjusted odds ratio (aOR) = 0.84; p < 0.001), past year MDE (aOR = 0.84; p < 0.001), and past year severe MDE (aOR = 0.82; p < 0.001). Psilocybin was associated with significantly lowered odds of a past year MDE (aOR = 0.90; p < 0.05) and past year severe MDE (aOR = 0.87; p < 0.05). All other substances either shared no relationship with a MDE or conferred increased odds of an MDE.

CONCLUSIONS

These results suggest that MDMA/ecstasy and psilocybin use is associated with lower risk of depression. Experimental studies are needed to test whether there is a causal association between use of these compounds and the alleviation of depressive symptoms.
