Biweekly Delivery of a Group-Based Adaptation of Written Exposure Therapy (WET) for PTSD in Residential Substance Treatment

Written exposure therapy (WET) is a brief intervention for posttraumatic stress disorder (PTSD) with promising and continually emerging research support. Given its efficiency in reducing symptom severity and resolving diagnoses, there is great interest in application to novel populations and settings. The current case series focuses on application of an adaptation of WET to three individuals participating in a residential substance use disorder treatment program in a group setting. The individuals had varying substance problems and trauma histories and all showed a favorable response. The series highlights the promise of an adaptation of WET as a concurrent treatment for PTSD in residential substance use treatment. Moreover, the case series suggests that an adaptation of WET has the potential to be successfully adapted to deliver services in a group environment and delivered in 2.5 weeks, thereby demonstrating the possibility of using an adaptation of WET as a means of maximizing the utilization of scarce resources to successfully treat a large number of individuals with PTSD in a time-limited residential treatment context.
