PURPOSE: Depressive disorders in children and adolescents have an enormous impact on their general quality of life. There is a clear need to effectively treat depression in this age group. Effects of psychotherapy can be enhanced by involving caregivers. In our systematic review and meta-analysis, we examine for the first time the effects of caregiver involvement in depression-specific interventions for children and adolescents. METHODS: We included randomized controlled trials examining the effects of interventions for children and adolescents with depression involving their caregivers or families compared to interventions without including caregivers. Primary outcome was the severity of childhood and adolescent depression. RESULTS: Overall, 19 randomized controlled trials could be included (N = 1553) that were highly heterogeneous regarding outcome measures or the extent of caregiver integration. We were able to include k = 17 studies in our meta-analysis and find a small but significant effect for family-involved interventions against active control conditions without family-involvement at post intervention (α = 0.05, d = 0.34; 0.07; 0.60; p = .01). CONCLUSIONS: We detected an overall significant but small effect of family/caregivers' involvement compared to control groups without it. Structured, guideline-based research is urgently needed to identify for which children/adolescents with depression, under what circumstances, and in what form the family should be effectively involved in their psychotherapy.
