Abstract

This individual participant data meta-analysis aimed to investigate the effectiveness of cognitive behavioral therapy with a trauma focus (CBT-TF) for posttraumatic stress disorder (PTSD). Furthermore, we examined the effect of moderators on PTSD symptom severity. This study included randomized controlled trials comparing CBT-TF to an inactive or active comparison group for adults with PTSD. The primary and secondary outcomes were PTSD symptom severity and remission, respectively. Moderators included sociodemographic and clinical variables. Twelve studies compared CBT-TF with inactive (n = 625) and 11 with active comparison conditions (n = 706). The one-stage individual participant data meta-analysis found that CBT-TF was more effective than inactive comparison conditions (β = -0.78; OR = 2.34) and not significantly different from active comparison conditions (β = 0.02; OR = 0.53) in reducing PTSD symptom severity and achieving PTSD remission, respectively. When comparing CBT-TF with inactive treatments, moderator analysis found that divorced participants had greater PTSD symptoms postintervention following CBT-TF than participants who were single, cohabitating, or married receiving CBT-TF, both in the completer (β = 0.93) and full-sample (β = 0.59) analyses. For the active treatment comparison, moderator analysis found that participants taking psychotropic medication had lower PTSD symptoms following CBT-TF than those not taking psychotropic medication in the completer analysis (β = -0.39). Based on our moderator analyses, further research is needed to understand the effect of psychotropic medication on the CBT-TF intervention process. Moreover, divorced participants with PTSD receiving CBT-TF might benefit from enhanced support. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
