Abstract

To date, the long-term effectiveness of psychological treatments in reducing post-traumatic stress disorder symptoms in children and adolescents has not been investigated extensively. This meta-analysis quantifies the long-term effects of psychological interventions in children and adolescents with PTSD symptoms and examines the period-dependent follow-up (FU) effects based on 47 studies. The mean FU effect sizes (ESs) for PTSD symptoms ranged from medium (between treatment ESs for controlled studies) to large (within treatment ESs for uncontrolled studies; pooled analysis including all studies). These effects were comparable to the post-treatment ESs, which suggests that the treatment effects remained stable. ESs did not differ depending on the length of the FU period (</>6 months). In randomized controlled trials (RCTs), as well as trials conducted with treatment as usual or active control groups, the long-term treatment effects for the reduction of PTSD symptoms were small. These results demonstrate the long-term effectiveness of psychological interventions in the treatment of PTSD in youth. However, more studies should include a FU assessment. Further research should focus on RCTs with long-term assessments, report comorbid symptoms and investigate the influence of potential moderators. Research is also warranted to determine how to improve the long-term effects of treatments for PTSD in youth.
