Interventions to reduce stress, anxiety and depression symptoms in teenagers – a systematic review

Abstract Introduction Stress, anxiety and depression symptoms are frequent in teenagers. Objectives: To identify the interventions effectively able to prevent or reduce anxiety, depression and psychological stress in adolescents; to assess the effectiveness, feasibility and transferability of the interventions. Methods Comprehensive systematic review was performed. Three steps searching strategy using the databases: PsycINFO, PubMed, SCOPUS, Cochrane Library, and Google Scholar identified 679 studies and reviews. Critical appraisal was performed by 2 reviewers, data extraction performed on finally selected 59 reviews, RCT, cohort studies focused on sample size, geographical context, setting, description of intervention, measures of primary and secondary outcomes. Results The considered interventions are: Internet-based multifaceted cognitive bias modification training (CBM), Internet (iCBT) or school-based cognitive behavioral group training (CBT), Social skills training (SST), Metacognitive therapy, Psychosocial Support Intervention, organized sports participation and voluntary outdoor play, school-based resilience-focused intervention, assertiveness group training, short-term psychoanalytic psychotherapy (STPP), brief psychosocial intervention (BPI), Guided Parent-Delivered Cognitive Behaviour Therapy (GPD-CBT), Internet-based self-support method. Conclusions Interventions for promoting mental health in adolescents have to combine parenting programs with leisure activities and balanced curriculum; various approaches (physical activity, music, sports participation) should be tailored into the national, community and school contexts. Resilience factors (relationship with parents, communications with peers), development of help-seeking behaviours and available self-help programs could support early detection and assistance. Most interventions showed positive effects on short and medium term and potential transferability. Key messages Regular screening for childhood adversities and traumas and screening of symptoms as feeling sad, hopeless, worried should be performed in adolescents as they get older. Besides mental health risk factors, interventions should target developmental risk factors in transitional stages from childhood to adolescence and from adolescence to young adulthood.
