Summary

The goal of this clinical trial is to test if Written Exposure Therapy (WET) works well in a group setting in patients with post-traumatic stress disorder (PTSD). The main questions it aims to answer are: * Does group WET lead to a reduction in symptoms of PTSD? * Is group WET better at reducing the number of patients that drop out of treatment in comparison to group Cognitive Processing Therapy (CPT)? Participants will: * Attend 6 weekly sessions of group WET that will be delivered online by two therapists (psychologist and social worker) * Complete questionnaires relating to their symptoms at different points throughout the treatment Researchers will evaluate change in PTSD symptoms over time for people who participate in group WET. They will also compare the results of group WET to the results of group CPT to see if group WET shows a similar reduction in symptoms of PTSD and fewer treatment drop-outs.

Detailed description

The primary objective of this study is to evaluate the effectiveness of group WET (G-WET) in reducing symptoms of PTSD in an outpatient hospital setting. In order to do so, we will evaluate outcomes of G-WET from pre- to post-treatment and at one month follow-up. We will also compare outcomes of G-WET to published benchmarks of individual WET outcomes and to a representative cohort of individuals who participate in group CPT at our clinic. A secondary aim of the study is to evaluate attendance and drop-out rates for group WET. In order to achieve this, we will recruit a sample of 63 individuals between the ages of 18 and 65 to participate in a group WET 6-session protocol (1 orientation session and 5 WET sessions) from an outpatient anxiety and related disorders clinic waitlist for group CPT. Participants will complete measures assessing PTSD, related symptoms (e.g., depression, anxiety) and group cohesion at pre-treatment, post-treatment, and 1-month follow-up. Attendance and drop-out rates will also be recorded. We hypothesize that group WET will be associated with significant reductions in PTSD symptoms and related symptoms and low dropout rates (i.e., less than 10%). We also hypothesize that outcomes for group WET will be comparable to those for group CPT and published individual WET benchmarks.

Interventions

Type	Name	Description
BEHAVIORAL	Group Written Exposure Therapy	Group Written Exposure Therapy (GWET) is a brief cognitive behavioural therapy for PTSD aimed at allowing patients to process their traumatic experiences in a safe environment. GWET will consist of 6 group sessions (1 orientation session and 5 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.
