Adolescent depressive disorders and family based interventions in the Family Options multicenter evaluation: study protocol for a randomized controlled trial

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

Background

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

Objectives

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

Search Methods

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

Selection Criteria

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

Data Collection and Analysis

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

Main Results

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

Authors' Conclusions

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

Positive Youth Development in Croatia: School and Family Factors Associated With Mental Health of Croatian Adolescents

Introduction

A framework for understanding the interrelationship of individual and environmental factors that influence adolescent health and well-being, as well as opportunities for policy-level interventions, is known as Positive Youth Development (PYD). The current study represents one of the largest studies of Croatian adolescents to date, and aimed to examine associations between school and family factors linked to PYD, and mental health outcomes experienced by Croatian youth.

Methods

A multi-site survey study was conducted among adolescents (N = 9,655) residing in the five most populous cities in Croatia, with the aim of examining cross-sectional associations of family and school factors with adolescent mental health. The mean age of participants was 16.3 years (SD = 1.2), and 52.5% of participants were female. School and family factors included school attachment, school commitment, family communication, and family satisfaction. Depression, anxiety, and stress were assessed as outcomes. Multigroup structural equation modeling (SEM) was used to examine relations of interest among female and male adolescents.

Results

Among school factors, increased school attachment was found to be significantly associated with reduced depression, anxiety, and stress for female adolescents, and with decreased depression and stress for male adolescents. Increased school commitment was significantly associated with decreased depression and anxiety for female adolescents; conversely, an increase in school commitment was associated with an increase in anxiety and stress for male adolescents. Increases in family communication were significantly associated with reduced depression, anxiety, and stress only for male adolescents, while increased family satisfaction was significantly associated with reduced depression, anxiety, and stress for female adolescents and with decreased depression and stress for male adolescents.

Conclusion

Findings suggest that interventions for mental health promotion and prevention of internalizing problems should address both school and family contexts, and may be more effective when accounting for differing developmental experiences of female and male adolescents.

Family functioning moderates the impact of depression treatment on adolescents' suicidal ideations

PURPOSE

The purpose of this study was to explore whether adolescent-perceived family functioning moderates the depression treatment effects on suicidal ideations.

METHODS

This is a nonpreregistered exploratory secondary analysis of the TADS RCT, which included four treatment groups: fluoxetine, CBT, their combination, and placebo. A random coefficients regression model with posteriori CONTRAST statements was conducted to examine the effects of depression treatment on adolescents' suicidal ideations over time (N = 439). Baron and Kenny's (1986) and Kraemer et al.'s (2002) approach was followed to explore family functioning as a potential moderator of the treatment effects on suicidal ideations over time.

RESULTS

Adolescents in the four treatment groups did not differ significantly in their suicidal ideations at initial status; however, those in the combination group had faster reduction in suicidality. Family functioning moderated the relationship between depression treatment and adolescents' suicidal ideations. In particular, the results revealed that for adolescents who reported positive family functioning (n = 249), treatment had a significant impact on their suicidal ideations over time. However, for adolescents who reported negative family functioning (n = 190), type of treatment did not have a differential effect on improvement in severity of suicidal ideation over time.

CONCLUSION

Findings provided evidence that the process by which depression treatment impacts adolescents' suicidality is contingent upon their family environment. Family-centered approaches to adolescent depression treatment are recommended.

Attachment-Based Family Therapy for Adolescent Substance Use: A Move to the Level of Systems

This paper provides an account of the theoretical basis of a family-based intervention called Behaviour Exchange and Systems Therapy (BEST). The model described here has also been applied to adolescents with substance abuse and other mental health problems such as depression and anxiety disorders in both children and adolescents. Evaluative studies of the model have been published including randomised clinical trials as well as qualitative analyses. The current paper discusses a theory of the family system as a discourse and represents an integration of aspects of attachment, psychoanalytic, and systems theories. Key concepts elaborated are the attachment-family system, the family as a single discourse, the use of segregation as a defense in relation to trauma and loss and its manifestation in a family narrative, and the role of the family secure base in affect regulation. The paper also briefly describes specific treatment techniques that are derived from the theoretical model. Our approach has wide application as a discourse focused treatment for children and adolescents using a family systems approach. Future work requires the comparison of this model to similar attachment-based models of intervention for children and families, further development and validation of measures able to be used for whole families in a clinical setting, and further empirical demonstration of treatment efficacy in a variety of clinical settings.

Review: Longitudinal trajectories of child and adolescent depressive symptoms and their predictors - a systematic review and meta-analysis

BACKGROUND

With depression predicted to contribute to an increased disease burden in coming decades, prevention efforts have become increasingly important. In order to prevent depression it is valuable to identify and classify longitudinal patterns of depressive symptoms across development, ideally beginning early in childhood. To achieve this, longitudinal studies are increasingly using person-centered data-analytic methods to model subgroups with similar developmental patterns (trajectories) of depressive symptoms.

METHOD

A search was completed for English language studies that longitudinally modeled depressive symptom trajectories in nonclinical populations with a baseline age of <19 years. Study characteristics were extracted, prevalence rates and risk factors were summarized, a random-effect meta-analysis was undertaken, and risk of bias analysis completed.

RESULTS

Twenty studies published between 2002 and 2015 were included. Participants were recruited at ages 4 through 17 (average age 12.34) and followed longitudinally for an average of 7.45 years. Between 3 and 11 trajectory subgroups were identified. A random pooled effect estimate identified 56% [95% Confidence Interval (CI) 46-65%] of the sampled study populations (N = 41,236) on 'No or low' depressive symptom trajectories and 26% (CI 14-40%) on a 'Moderate' trajectory. 'High', 'Increasing', and 'Decreasing' depressive symptom subgroups were evident for 12% (CI 8-17%). Moderate symptoms were associated with poorer adjustment and outcomes relative to low symptom groups. 'High' or 'Increasing' trajectories were predominantly predicted by: female gender, low socioeconomic status, higher stress reactivity; conduct issues; substance misuse, and problems in peer and parental relationships.

CONCLUSIONS

The review highlighted consistent evidence of subgroups of children and adolescents who differ in their depressive symptom development over time. The findings suggest preventative interventions should evaluate the longer term benefits of increasing membership in low and moderate trajectories, while also targeting reductions in high-risk subgroups. Considerable between-study method and measurement variation indicate the need for future trajectory studies to use standardized methods.

A Multi-Family Group Intervention for Adolescent Depression: The BEST MOOD Program

Depression is the most common mental disorder for young people, and it is associated with educational underachievement, self-harm, and suicidality. Current psychological therapies for adolescent depression are usually focused only on individual-level change and often neglect family or contextual influences. The efficacy of interventions may be enhanced with a broader therapeutic focus on family factors such as communication, conflict, support, and cohesion. This article describes a structured multi-family group approach to the treatment of adolescent depression: Behaviour Exchange Systems Therapy for adolescent depression (BEST MOOD). BEST MOOD is a manualized intervention that is designed to address both individual and family factors in the treatment of adolescent depression. BEST MOOD adopts a family systems approach that also incorporates psychoeducation and elements of attachment theories. The program consists of eight multifamily group therapy sessions delivered over 2 hours per week, where parents attend the first four sessions and young people and siblings join from week 5. The program design is specifically aimed to engage youth who are initially resistant to treatment and to optimize youth and family mental health outcomes. This article presents an overview of the theoretical model, session content, and evaluations to date, and provides a case study to illustrate the approach.

Offspring of Parents with Schizophrenia: A Systematic Review of Developmental Features Across Childhood

A significant body of longitudinal research has followed the offspring of parents with schizophrenia. This article presents a systematic review of 46 separate papers presenting the results of 18 longitudinal studies that have followed children who are at familial high risk of developing psychotic disorders. The studies suggest that these children do show distinct developmental patterns characterized by higher rates of obstetric complication, neurodevelopmental features such as motor and cognitive deficits, and distinctive social behavior. This review summarizes those findings according to child developmental stages. Twelve of the studies followed offspring into adulthood and examined psychiatric diagnoses. From 15% to 40% of children at familial high risk developed psychotic disorders in adulthood. Many also received other psychiatric diagnoses such as mood or anxiety disorders. This combination of results suggests that offspring of parents with schizophrenia are at high risk not just for schizophrenia but, more broadly, for poor developmental and general mental health outcomes. The clinical implications of the findings are discussed, as are new prognostic strategies and potential programs for selective prevention.

The Impact on Family Functioning of Social Media Use by Depressed Adolescents: A Qualitative Analysis of the Family Options Study

BACKGROUND

Adolescent depression is a prevalent mental health problem, which can have a major impact on family cohesion. In such circumstances, excessive use of the Internet by adolescents may exacerbate family conflict and lack of cohesion. The current study aims to explore these patterns within an intervention study for depressed adolescents.

METHOD

The current study draws upon data collected from parents within the family options randomized controlled trial that examined family based interventions for adolescent depression (12-18 years old) in Melbourne, Australia (2012-2014). Inclusion in the trial required adolescents to meet diagnostic criteria for a major depressive disorder via the Structured Clinical Interview for DSM-IV Childhood Disorders. The transcripts of sessions were examined using qualitative thematic analysis. The transcribed sessions consisted of 56 h of recordings in total from 39 parents who took part in the interventions.

RESULTS

The thematic analysis explored parental perceptions of their adolescent's use of social media (SM) and access to Internet content, focusing on the possible relationship between adolescent Internet use and the adolescent's depressive disorder. Two overarching themes emerged as follows: the sense of loss of parental control over the family environment and parents' perceived inability to protect their adolescent from material encountered on the Internet and social interactions via SM.

CONCLUSION

Parents within the context of family based treatments felt that prolonged exposure to SM exposed their already vulnerable child to additional stressors and risks. The thematic analysis uncovered a sense of parental despair and lack of control, which is consistent with their perception of SM and the Internet as relentless and threatening to their parental authority and family cohesion.

Depression and suicidal behavior in adolescents: a multi-informant and multi-methods approach to diagnostic classification

BACKGROUND

Informant discrepancies have been reported between parent and adolescent measures of depressive disorders and suicidality. We aimed to examine the concordance between adolescent and parent ratings of depressive disorder using both clinical interview and questionnaire measures and assess multi-informant and multi-method approaches to classification.

METHOD

Within the context of assessment of eligibility for a randomized clinical trial, 50 parent-adolescent pairs (mean age of adolescents = 15.0 years) were interviewed separately with a structured diagnostic interview for depression, the KID-SCID. Adolescent self-report and parent-report versions of the Strengths and Difficulties Questionnaire, the Short Mood and Feelings Questionnaire and the Depressive Experiences Questionnaire were also administered. We examined the diagnostic concordance rates of the parent vs. adolescent structured interview methods and the prediction of adolescent diagnosis via questionnaire methods.

RESULTS

Parent proxy reporting of adolescent depression and suicidal thoughts and behavior is not strongly concordant with adolescent report. Adolescent self-reported symptoms on depression scales provide a more accurate report of diagnosable adolescent depression than parent proxy reports of adolescent depressive symptoms. Adolescent self-report measures can be combined to improve the accuracy of classification. Parents tend to over report their adolescent's depressive symptoms while under reporting their suicidal thoughts and behavior.

CONCLUSION

Parent proxy report is clearly less reliable than the adolescent's own report of their symptoms and subjective experiences, and could be considered inaccurate for research purposes. While parent report would still be sought clinically where an adolescent refuses to provide information, our findings suggest that parent reporting of adolescent suicidality should be interpreted with caution.
