Adaptation of a school-based mental health program for adolescents in Vietnam

Implementation outcomes in psychosocial intervention studies for children and adolescents living in low- and middle-income countries: A systematic review

Psychosocial interventions play a key role in addressing mental health and substance use needs for children and adolescents living in low- and middle-income countries (LMICs). While research efforts have primarily focused on their effectiveness, implementation outcomes also require examining. We conducted a systematic review of qualitative, quantitative, and mixed-methods studies (PROSPERO: CRD42022335997) to synthesize the literature on implementation outcomes for psychosocial interventions for children and adolescents in LMICs. We searched Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Web of Science, PsychINFO, and Global Health through April 2023. Data were extracted and quality appraised through the Mixed Methods Appraisal Tool (MMAT) independently by two reviewers. A total of 13,380 records were screened, and 87 studies met inclusion criteria. Feasibility was the most reported implementation outcome (69, 79%), followed by acceptability (60, 69%), and fidelity (32, 37%). Appropriateness was assessed in 11 studies (13%), implementation costs in 10 (11%), and sustainability in one (1%). None of the included studies reported on penetration or adoption. Despite a growing body of evidence for implementation research in child and adolescent global mental health, most research focused on earlier-stage implementation outcomes, assessing them in research-controlled settings. To overcome this, future efforts should focus on assessing interventions in routine care, assessing later-stage implementation outcomes through standardized tools.

School-based universal mental health promotion intervention for adolescents in Vietnam: Two-arm, parallel, controlled trial

The aim of this study was to evaluate the effects of Happy House, a universal school-based programme, in reducing adolescents' depressive symptoms and improving their mental well-being, coping self-efficacy and school connectedness. This was a school-based, two-arm parallel controlled trial. Depressive symptoms were measured using the Centre for Epidemiologic Studies Depression Scale. Data were collected at recruitment, and at 2 weeks and 6 months post-intervention. Mixed-effect models were conducted to estimate the effects of the intervention on the outcomes. A total of 1,084 students were recruited. At 2 weeks post-intervention, the effect size on depressive symptoms was 0.11 (p = 0.011) and the odds of having clinically significant depressive symptoms were lower in the intervention compared to the control (0.56, p = 0.027). Both of these were no longer significant at 6 months post-intervention. Psychological well-being mean scores in the intervention were significantly higher than in the control at 2 weeks post-intervention (effect size 0.13). Coping self-efficacy mean scores were significantly higher in the intervention group at both 2-week and 6-month post-intervention (effect sizes from 0.17 to 0.26). Data support the potential of Happy House to reduce the prevalence of adolescent mental health problems and to promote positive mental health in the school context in Vietnam.
