Extended Group Written Exposure Therapy for Comorbid PTSD and BPD (Traits)
Sponsor: St. Joseph's Healthcare Hamilton
Summary
The goal of this open label trial is to evaluate the effectiveness of virtual group extended Written Exposure Therapy (GE-WET) in reducing Post-Traumatic Stress Disorder (PTSD) symptoms in patients with comorbid PTSD and Borderline Personality Disorder (BPD) or BPD traits. GE-WET involves attending weekly 2-hour group WET sessions for the duration of 10 weeks, in which they write about their trauma experience using specific instructions. This study will be conducted at St. Joseph's Healthcare Hamilton's Community Psychiatry Clinic with clients wait listed for PTSD treatment (ages 18- 65, any gender, co-morbid PTSD and BPD/BPD traits). The main questions this study aims to answer are: Does GE-WET reduce PTSD symptoms (based on PCL-5 measures) in this population (outpatient clients ages 18-65 of any gender, with a diagnosis of PTSD and BPD or BPD traits)? Does GE-WET result in reduced drop-out rates for this population, compared to that of other evidence-based treatment for PTSD? What are participants subjective experience of GE-WET?

Interventions
Group Written Exposure Therapy
Group Extended Written Exposure Therapy (GE-WET) is a time-limited cognitive behavioural therapy for Posttraumatic Stress Disorder (PTSD) aimed at allowing patients to process their traumatic experiences in a safe environment. GE-WET will consist of 10 weekly group sessions. Participants will be asked to complete weekly in-session written exposures where they will recount their traumatic experience. The written exposure will be followed by a guided discussion about the experience of writing the exposure. There is no homework assigned between sessions. However, group members will be asked to refrain from avoiding thinking about the trauma between sessions.
