The prevalence of post-traumatic stress disorder symptoms in children and adolescents requires school psychologists and counsellors to be informed of evidence-based elements of interventions through which they can tailor their treatment to the individual in a school context. This meta-analysis identified common practice elements within evidence-based trauma interventions for schools. A small to medium effect size was identified in the 10 randomised controlled trials (RCTs) included in this meta-analysis. Within these RCTs, 31 common practice elements were identified, with social skills training, coping skills training, relaxation techniques, psychoeducation, mind-body techniques, group work and creative-expressive techniques correlating with the most effective outcomes. The findings suggest that common practice elements exist across multiple school-based trauma interventions of varying modalities.
