Prolonged exposure (PE) therapy is highly effective in reducing symptoms of PTSD, but it is often difficult for veterans to engage in and adhere to all prescribed components of this therapy. This article details a preliminary, feasibility test of Peer Enhanced Exposure Therapy (PEET), a new, manualized intervention allowing specially trained peer specialists who have completed PE to facilitate treatment engagement and adherence during PE by providing individual in-person and telephone support, coordinating peer support services with PE therapists. This case study outlines the theoretical foundations, session content, and both qualitative and quantitative data for two of the first veterans and first peer specialists involved in implementation of PEET. In this case study, the veterans made gains in symptom management expected in PE. Despite the historically high dropout from PE, both veterans completed a full course of PE. There was also evidence of improvement in rehabilitation outcomes, such as community integration, independent living skills, interacting with others, and maintaining friends and activities. Data support the feasibility and acceptability of the intervention; implications for future research are discussed.
