Electronic searches will be supplemented by a comprehensive grey literature search in Conference proceedings and trial registries. Randomised controlled trials (RCTs) comparing psychological or psychosocial treatments for PTSD with control conditions in all age groups will be included. The primary outcome is the between-treatments efficacy for PTSD that refers to the outcomes of the RCTs included in the meta-analysis. Effect sizes will be calculated for all comparisons and pooled with a fixed effects model or a random effects model. Differences in the efficacy of psychological\/psychosocial therapies for PTSD across the age groups will be examined by stratified analyses and meta-regression analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>Data used in this study will be anonymised.
