About

The purpose of this study is to examine whether Written Exposure Therapy (WET) can be effectively delivered virtually and in a group format for the treatment of Post-Traumatic Stress Disorder in a military and police population. The objective of this study is to assess treatment feasibility and acceptability, drop out rates, changes in severity of trauma-related symptoms and symptoms of depression, quality of life, and the need for further trauma-focused treatment (TFT) for the the delivery of WET as a virtual, group based intervention.

Full description

This study will assess the efficacy and acceptability of WET being delivered virtually and in a group format for the treatment of PTSD through the Operational Stress Injury Clinic (OSIC) at Deer Lodge Centre.

WET is offered in small groups of 10 patients. This study will follow 8 iterations of the group for a potential total of 80 participants in this study. Each WET group session will be facilitated by two OSIC clinicians, at least one of whom will be a clinical psychologist. Each session, administered via the Zoom app for healthcare, will start with a brief check in, then instructions will be provided to the whole group. Each group will receive a total of 5 therapy sessions, each of which will last approximately 1.5hrs.

Prior to the first WET session, participants will be asked to complete three clinical measures: Patient Health Questionnaire- 9 (PHQ-9), PTSD Checklist for DSM-5 (PCL-5, weekly version), and Outcome Questionnaire-45 (OQ-45). Participants will be asked to complete the PCL-5 prior to each session. Participants will also complete a Treatment Acceptability/Adherence Scale prior to the start of the second session.

Following the final session of therapy, participants will be asked to complete the three clinical assessment questionnaires (PHQ-9, PCL-5, and OQ-45) at 1 week, 1 month, and 3 months post-treatment. A research assistant will also follow-up with each participant at the 3-month mark to ask whether they have sought or attended further psychological treatment since the end of the WET sessions.
