Prolonged Exposure Therapy for PTSD and Opioid Use Disorder

Within the general population, prolonged exposure therapy (PET) is a widely-used, empirically-supported and manualized therapy that is regarded as a first-line cognitive-behavioral treatment for posttraumatic stress disorder (PTSD). PET is designed to disrupt the cycle of anxiety and avoidance that characterizes PTSD via sustained imaginal and in-vivo exposure exercises that deliberately and systematically expose patients to painful memories and current, real-life trauma reminders that were previously avoided, yet not inherently harmful. Overall, PET has well-documented efficacy for reducing PTSD symptom severity in both civilian and veteran populations. PET is effective for reducing PTSD symptoms regardless of whether it is delivered remotely or face-to-face. Recent data also suggest that PET can improve PTSD symptoms without exacerbating substance use or craving among patients with substance use disorders when PET and substance use disorder treatment are delivered concurrently.

Participants will earn vouchers that have monetary value for attending scheduled PET appointments. Each consecutive attended session will increase the voucher amount so that each consecutively attended appointment is worth an incrementally higher dollar amount. To support completion of the full 12-week PET protocol, we will also incorporate additional strategically-placed bonuses into the reinforcement schedule with the goal of maximizing the percentage of subjects who complete the full 12-session protocol. First, to support consistent (vs. sporadic) attendance, participants will receive a bonus for every two consecutive sessions attended. Second, to support completion of the full PET protocol, participants will receive an additional bonus upon completion of Session 12.
