Purpose: A meta-analysis of group interventions to reduce post-traumatic stress symptoms (PTSS) and/or depression among refugee and immigrant children and adolescents. Methods: A systematic search was followed by independent reviews of each study for risk of bias. The meta-analysis pooled between- and within-condition effect sizes on PTSS and depression across studies using a random effects model. Results: The search yielded 16 studies utilizing eight interventions involving 976 participants. For all studies, within conditions, there were good effects on PTSS (d = −0.66, 95% CI [−0.86, −0.46]) and depression (d = −0.51, 95% CI [−0.79, −0.23]) with substantial heterogeneity. For studies with control groups, the between-group effect sizes yielded a small effect on PTSS (d = −0.31, 95% CI [−0.65, 0.03]) with no significant effect on depression. Conclusions: The interventions helped to reduce PTSS and depression. Most studies lacked rigorous designs and provided little information on group variables needed for replication.
