Participants: We recruited a sample of 50 Veterans with PTSD who completed study measures at a screening session. Methods: Participants completed self-report measures of exposure to potentially traumatic events, trauma-related guilt (hindsight bias, wrongdoing, and lack of justification) and trauma-related sleep disturbance as measured by a self-report scale and clinician ratings of nightmare severity.
