To compare effectiveness of evidence-based psychotherapy EBP for PTS in Iraq and Afghanistan War Veterans who use Veterans Health Administration VHA care Aim 1, we used an approach that mimics a sequence of randomized trials by implementing propensity score models within each trial to achieve covariate balance, using matching. We found that Veterans who completed EBP for PTS experienced a significant improvement in PTSD Checklist PCL scores compared to the non-completers i.e., 5.4-point improvement on the PCL. We also completed an analysis of factors associated with completing EBP for PTS Aim 2. Using ordered logistic regression, we identified factors associated with achievement of hierarchal outcome categories no EBP, EBP dropout, EBP completion during any 24-week period. Using Cox proportional hazards regression, we also assessed factors associated with faster time to completion of PE or CPT from VA mental health entry. Over a 15-year period, 265,566 Iraq and Afghanistan War Veterans with PTS initiated psychotherapy in the VHA. While 22.8 initiated an EBP, only 9.1 completed treatment. Those who completed did so about three years after their initial mental health visit. Several factors were associated with EBP completion, including history of military sexual trauma MST, older age, gender, and raceethnicity.
