  • Description: ObjectiveTo assess whether changes in negative trauma-related cognitions play an important role in reducing symptoms of posttraumatic stress disorder (PTSD) and depression during prolonged exposure therapy for adolescents (PE-A). MethodSecondary analysis of data from a randomized controlled trial comparing PE-A with client-centered therapy (CCT) for PTSD. Participants were 61 adolescent female sexual assault survivors ages 13–18 who received 8–14 weekly sessions of PE-A or CCT at a community rape crisis center. PTSD severity was assessed at baseline, mid-treatment, post-treatment, and 3-months post-treatment. Participants also completed self-report measures of negative posttraumatic cognitions and depressive symptoms at the same assessment points. ResultsCross lag panel mediation analyses showed that change in negative trauma-related cognitions mediated change in PTSD symptoms and depressive symptoms whereas change in PTSD and depressive symptoms did not mediate change in negative cognitions. ConclusionOur findings support EPT and suggest that change in negative trauma-related cognitions is a mechanism of both PE-A and CCT. •Change in negative cognitions mediated change in PTSD and depressive symptoms.•Change in PTSD and depressive symptoms did not mediate change in negative cognitions.•The mediating effect of negative cognitions was stronger in the exposure group.•Negative cognitions are a mechanism of prolonged exposure for adolescents with PTSD.
