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.
Value creation and value appropriation in public and nonprofit organizations
In recent years, strategy scholarship expanded its scope beyond the realm of private firms. Despite notable advances, the field still lacks theoretical and empirical frameworks for fully understanding how public and nonprofit organizations interact with private firms to create and appropriate value. By recognizing the inherent complexity of interactions between organizations with different purposes and…
