RecruitingBehavioural interventionNovel Telemedicine-Delivered Prolonged Exposure Therapy for Treating PTSD in Individuals With OUDAmong individuals with opioid use disorder (OUD), posttraumatic stress disorder (PTSD) presents a significant clinical challenge. The prevalence of PTSD is substantially higher in individuals with OUD than in the general population, with nearly 90% reporting lifetime trauma exposure and 33% meeting diagnostic criteria for PTSD. The primary objective of this study is to evaluate the efficacy of a novel telemedicine-delivered prolonged exposure therapy protocol for improving PE attendance and reducing PTSD symptom severity in individuals with concurrent PTSD and OUD.
