This is a prospective randomized controlled trial examining the efficacy of brief Prolonged Exposure Therapy (Brief PE) delivered to individuals admitted to a Level I Trauma Center to reduce PTSD symptoms. The overall goal of this project is to test a Brief PE (three 60-minute sessions) to reduce psychological distress after injury and to mitigate long-term post-injury distress including PTSD as well as secondary health outcomes (including depression, general anxiety, pain, and quality of life) at 1, 3, and 6 months from baseline. The intervention group (Brief PE) will be compared to standard clinical care with treatment as usual (TAU).
