Enhancing Exposure Therapy for Post-traumatic Stress Disorder

This study is investigating a new brief psychotherapy for post-traumatic stress disorder (PTSD) which, modifies an already proven psychotherapy for PTSD by adding two new components and modifying several others. The goal of the study is to determine whether this experimental treatment outperforms the well-established standard treatment. Individuals between the ages of 18-65 with chronic PTSD are randomly assigned to one of three psychotherapy conditions: (a) brief enhanced exposure therapy; (b) standard prolonged exposure therapy; and (c) delayed standard exposure therapy. All study participants undergo a phone and face-to-face screening assessment to determine study eligibility and baseline (pretreatment-Week 0) symptom severity. Upon completing treatment, participants undergo three additional assessment visits (Week 6, Week 10, and Week 22). During each of these outcome assessment visits, participants complete a structured clinical interview and a battery of computer-administered questionnaires.
