Cost-effectiveness of Brief Behavioral Therapy for Pediatric Anxiety and Depression in Primary Care

Is behavioural activation an effective treatment for depression in children and adolescents? An updated systematic review and meta-analysis

Behavioural Activation (BA)-a brief therapy based on the scheduling of enjoyable, purposeful and rewarding activities-is an effective and cost-effective treatment for depression in adults that shows promise for children and adolescents. We provide an update on a previous systematic review of evidence on BA-delivered in-person, telephone, or online-for depression and comorbid anxiety in children and adolescents. We conducted systematic literature searches in 6 databases up to February 2024. We included all study designs evaluating BA with participants up to 18 years old with diagnosable depression, as established by a validated screening tool or diagnostic manual. We used the Moncrieff Scale and the Cochrane Risk of Bias tool to assess study quality. We summarised the findings of all study types with a narrative synthesis and of randomised controlled trials (RCTs) with a meta-analysis. Overall, 24 studies (6 RCTs, 18 pre-post evaluations, n = 2,758) met our inclusion criteria. A meta-analysis of 4 RCTs (n = 156) showed that BA has a small effect of 0.24 (Hedge's adjusted g) in reducing depression symptoms compared to a waiting-list control, usual care and other therapies. Online and telephone-facilitated BA was shown to be feasible in 3 studies and effective in 1. Outcomes on comorbid anxiety were mixed. No economic evaluations met our inclusion criteria. BA shows sufficient promise as an intervention for reducing depression symptoms in children and adolescents to justify the need for further RCTs, providing that five conditions are met: studies are powered to detect a minimal clinically important difference; BA materials are fit-for-purpose to produce clinically meaningful change; follow-ups are longer than 6 months; primary outcomes are child-reported; and intervention costs, resource use and adverse events are reported.

Impact of trauma exposure and depression comorbidity on response to transdiagnostic behavioral therapy for pediatric anxiety and depression

By adolescence, two-thirds of youth report exposure to at least one traumatic event, yet the impact of trauma history is not routinely considered when evaluating the effect of psychotherapeutic interventions. Trauma may be a particularly important moderator of the effects of transdiagnostic therapies for emotional disorders, as trauma exposure is associated with risk for the development of comorbid depression and anxiety. The current study examined the history of trauma exposure and the presence of clinically significant depression as moderators of treatment outcomes in the Brief Behavioral Therapy (BBT) trial, the largest study of transdiagnostic psychotherapy for youth. Youths (age 8-16 years) were randomized to BBT (n = 89) based in pediatric primary care or assisted referral to outpatient community care (ARC; n = 86). Clinical response, functioning, anxiety symptoms, and depression symptoms were assessed at post-treatment (Week 16) and at follow-up (Week 32). A significant three-way interaction emerged between the treatment group, comorbid depression, and trauma exposure. BBT was broadly effective for 3/4 of the sample, but, for anxious-depressed youth with trauma exposure, BBT never significantly separated from ARC. Differences in outcome were not accounted for by other participant characteristics or by therapist-rated measures of alliance, youth engagement, or homework completion. Implications for models of learning and for intervention theory and development are discussed.

Early indicators of response to transdiagnostic treatment of pediatric anxiety and depression

BACKGROUND

Pediatric anxiety and depression are prevalent, impairing, and highly comorbid. Available evidence-based treatments have an average response rate of 60%. One path to increasing response may be to identify likely non-responders midway through treatment to adjust course prior to completing an episode of care. The aims of this study, thus, were to identify predictors of post-intervention response assessing (a) mid-treatment symptom severity, (b) session-by-session treatment process factors, and (c) a model optimizing the combination of these.

METHOD

Data were drawn from the treatment arm (N = 95, ages 8-16) of a randomized transdiagnostic intervention trial (Msessions  = 11.2). Mid-point measures of youth- and parent-reported anxiety and depression were collected, and therapists rated homework completion, youth and parent engagement, and youth therapeutic alliance at each session. Logistic regression was used to predict response on the Clinical Global Impression Improvement Scale (CGI-I ≤2) rated by independent evaluators masked to treatment condition.

RESULTS

Mid-point symptom measures were significant predictors of treatment response, as were therapist-ratings of youth and parent engagement, therapeutic alliance, and homework completion. Therapist ratings were significant when tested as mean ratings summing across the first eight sessions of treatment (all ps < .004) and at individual session points (all ps <0.05). A combined prediction model included youth-reported anxiety, parent-reported depression, youth engagement at Session 2, and parent engagement at Session 8. This model correctly classified 76.5% of youth as non-responders and 91.3% as responders at post-treatment (Nagelkerke R2  = .59, χ2 (4, 80) = 46.54, p < .001).

CONCLUSION

This study provides initial evidence that response to transdiagnostic intervention for pediatric anxiety and depression may be reliably predicted by mid-point. These data may serve as foundational evidence to develop adaptive treatment strategies to personalize intervention, correct treatment course, and optimize outcomes for youth with anxiety and depression.

Efficacy of a digital mental health intervention embedded in routine care compared with treatment as usual in adolescents and young adults with moderate depressive symptoms: protocol for randomised controlled trial

INTRODUCTION

There are unmet mental health needs of depressed adolescents and young adults (AYAs) across the USA. Behavioural technology adequately integrated into clinical care delivery has potential to improve care access and efficiency. This multisite randomised controlled trial evaluates how a coach-enhanced digital cognitive behavioural intervention (dCBI) enhances usual care for depressed AYAs in paediatric practices with minority enriched samples.

METHODS AND ANALYSIS

Participants (n=750) ages 16-22 who meet threshold criteria for depressive severity (Patient Health Questionnaire-9; PHQ-9 score 10-24) will be recruited through paediatric practices across three academic institutions (Boston, Pittsburgh and San Diego). Participants will be randomised to 12 weeks of dCBI+treatment as usual (TAU) (n=450) or TAU alone (n=300) in outpatient paediatric practices. Assessments will be completed at baseline, 6 weeks and 12 weeks with the primary outcome being improvement in clinician-rated and self-reported depressive severity (Children's Depression Rating Scale-Revised and PHQ-9) and secondary outcomes being self-reported suicidal ideation (item 9 on PHQ-9), anxiety severity (Generalised Anxiety Disorder), general quality of life (Satisfaction with Life Scale) and general functioning (Children's Global Assessment Scale). The study design is an intent-to-treat mixed effects regression with group, and covariates nested within the sites.

ETHICS AND DISSEMINATION

All participants or their parent/guardian (under 18 years or unemancipated) will give informed consent to a study team member. All data are expected to be collected over 18 months. The Institutional Review Board (IRB) is a board at each institution in the United States that reviews and monitors research involving human subjects. IRB approval from the University of Pittsburgh was obtained on 30 November 2021 (STUDY21080150), from the University of California San Diego's Human Research Protection Program IRB on 14 July 2022 (802047), and from the Boston Children's Hospital IRB on 25 October 2022 (P00040987). Full study results are planned to be published within 2 years of initial study recruitment (October 2024). Dissemination of findings will occur in peer-reviewed journals, professional conferences and through reports to participating entities and stakeholders.

Brief Behavioral Therapy for Anxiety and Depression in Pediatric Primary Care: Breadth of Intervention Impact

OBJECTIVE

To report on broad-based outcomes of the Brief Behavioral Therapy (BBT) trial for pediatric anxiety and depression. Secondary data analyses expand on previous reports by assessing diagnostic remission and independent functioning, impact on targeted psychopathology, and spillover effects on non-targeted outcomes.

METHOD

Youth (N = 185; 8-16.9 years; 58% female; 78% White; 21% Hispanic) with anxiety and/or depression were eligible for this multi-site trial. Enrolled youth were randomly assigned to receive 8 to 12 sessions of BBT in primary care or assisted referral to outpatient care (ARC). Assessments were conducted 16 and 32 weeks post randomization.

RESULTS

BBT was superior to ARC on remission of all targeted diagnoses (week 16: 56.8% vs 28.2%, p < .001; week 32: 62.5% vs 38.9%, p = .004), clinician-rated independent functioning (week 16: 75.0% vs 45.7%, p < .001; week 32: 81.2% vs 55.7%, p < .001), and on measures of anxiety, depression, suicide items, total comorbid behavioral and emotional problems, and hyperactivity (d = 0.21-0.49). Moderation analyses revealed superior outcomes for Hispanic youth in BBT vs ARC for diagnostic remission, anxiety, emotional problems, and parent-child conflict. Youth depression at baseline moderated effects on peer problems and parent-child conflict, with effects favoring BBT. Significant main and moderated effects of BBT on change in non-targeted outcomes were largely mediated by change in anxiety (24.2%-49.3% of total effects mediated).

CONCLUSION

BBT has positive effects on youth, mediated by the strong impact of the intervention on anxiety. Analyses continue to support positive outcomes for Hispanic youth, suggesting that BBT is a broadly effective transdiagnostic treatment option for diverse populations.

A Digital Cognitive-Behavioral Intervention for Depression and Anxiety Among Adolescents and Young Adults

Adolescents and young adults frequently experience anxiety and depression. The authors evaluated engagement in and effects of a coach-enhanced digital cognitive-behavioral intervention (dCBI; RxWell) targeting emotional distress in this age group. The dCBI app was prescribed to 506 adolescents and young adults at 35 pediatric practices; 278 enrolled in the app, of whom 58% engaged and 63% messaged their coach. Patients completed monthly General Anxiety Disorder-7 and eight-item Patient Health Questionnaire assessments, and a subset completed qualitative interviews. The dCBI app was associated with a significant reduction in anxiety and depression at 1 and 3 months. A dCBI is feasible as part of routine pediatric care and associated with reduced emotional distress.

Promoting Racial/Ethnic Equity in Psychosocial Treatment Outcomes for Child and Adolescent Anxiety and Depression

Anxiety and depression are the most prevalent and least treated pediatric mental health problems. Racial/ethnic minority youths face greater risks for developing anxiety and depression and experience higher burden as they are less likely to receive adequate mental health services for these conditions or to have their needs met. Further, standard evidence‐based interventions for youth anxiety and depression may show diminished effects with racial/ethnic minority youths and with families of lower socioeconomic status. While community‐level interventions to combat structural racism and reduce population‐level risk are sorely needed, many youths will continue to require acute treatment services for anxiety and depression and interventionists must understand how to bring equity to the forefront of care. In this review, we adopt a health system framework to examine racial/ethnic disparities in system‐, intervention‐, provider‐, and patient‐level factors for psychosocial treatment of pediatric anxiety and depression. Current evidence on disparities in access and in efficacy of psychosocial intervention for anxious and depressed youths is summarized, and we use our work in primary care as a case example of adapting an intervention to mitigate disparities and increase equity. We conclude with recommendations for disparity action targets at each level of the health system framework and provide example strategies for intervening on these mechanisms to improve the outcomes of racial/ethnic minority youths.

Racial/ethnic minority youths face greater risks for developing anxiety and depression and experience higher burden from disorder as they are less likely to receive adequate mental health services for these conditions or to have their needs met.

Increasing access to services for anxiety and depression is of critical and immediate importance for racial/ethnic minority families. Issues of access may be associated with the physical location of services (e.g., primary care or telehealth) or with barriers of language, income, or financing.

Both service settings and research treatment protocols frequently require families of ethnic/racial minority youths to fit themselves to the demands of care, in ways that may not be culturally compatible (e.g., little parent involvement in treatment) or practically feasible (i.e., weekly sessions during parent working hours). Whenever possible, non‐essential aspects of intervention should be freed to match patient preferences and constraints, and interventions for anxiety and depression should be adopted that have broad impacts and options for personalization of goals.

A Mental Health Drop-In Centre Offering Brief Transdiagnostic Psychological Assessment and Treatment in a Paediatric Hospital Setting: A One-Year Descriptive Study

AIM

This study was part of a broader project to examine the acceptability, feasibility and impact of a transdiagnostic mental health drop-in centre offering brief psychological assessment and treatment for children and young people and/or their families with mental health needs in the context of long-term physical health conditions (LTCs). The aims of this investigation were to characterise: (i) the use of such a centre, (ii) the demographics and symptoms of those presenting to the centre, and (iii) the types of support that are requested and/or indicated.

METHODS

A mental health "booth" was located in reception of a national paediatric hospital over one year. Characteristics of young people with LTCs and their siblings/parents attending the booth were defined. Emotional/behavioural symptoms were measured using standardised questionnaires including the Strengths and Difficulties Questionnaire (SDQ). Participants subsequently received one of four categories of intervention: brief transdiagnostic cognitive behaviour therapy (CBT), referral to other services, neurodevelopmental assessment or signposting to resources.

RESULTS

One hundred and twenty-eight participants were recruited. The mean age of young people was 9.14 years (standard deviation: 4.28); 61% identified as white and 45% were male. Over half of young people recruited scored in the clinical range with respect to the SDQ. Presenting problems included: anxiety (49%), challenging behaviour (35%), low mood (22%) and other (15%).

CONCLUSIONS

A considerable proportion of young people with LTC in a paediatric hospital scored in the clinical range for common mental health problems, indicating a potential for psychological interventions.
