Abstract

Externalizing behavior problems are a common concern among youth and can be associated with significant problems. As such, the need for effective treatment is evident. While research on psychosocial interventions has been promising, the specific efficacy of youth group therapy has not been assessed in a meta-analysis. Objectives: to assess group therapy's efficacy for youth with behavioral issues and whether treatment effects are moderated by study, patient, leader, or group characteristics. Method: major databases were used to identify and screen potential articles based on inclusion criteria. Included studied were analyzed in a random effects meta-analysis, and potential moderators were assessed. Results: we analyzed 30 studies representing 2,818 youth with behavior problems. Group therapy showed a significant, small effect (g = 0.47) on externalizing behavior concerns (EBCs). There were also significant effects on several secondary outcomes including aggressive cognitions, anger, internalizing symptoms, and social skills/interpersonal functioning. The only significant moderating variables was the inclusion of a parent component to treatment, with group treatments including a parent component being less effective. Discussion: this meta-analysis provides promising evidence on the efficacy of group therapy, with outcomes being comparable to what has been reported in past meta-analyses on psychosocial treatments for behavior problems. Future research is needed to clarify discrepancies in the literature, replicate the present findings, and otherwise understand the ideal treatments.
