Clinical Trial Summary

To investigate if written exposure therapy is feasible for patients with post-traumatic stress disorder

Description:

A non-inferiority trial in JAMA Psychiatry showed that written exposure therapy (WET) was non-inferior to a gold standard CBT treatment. In comparison to other trauma-focused CBT protocols, WET generally demands less therapist-time, and specifically, less than half compared to CBT that consists of 12 weekly sessions á 60 minutes. The aim of this study is to translate and replicate these results in a Swedish context. This first step is a small feasibility trial which will guide a subsequent large-scale trial.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5)	Change in symptoms of post traumatic stress from baseline to post treatment and follow up (6 months). The PTSD Checklist for DSM-5 (PCL-5) is a 20-item self-report measure that assesses the presence and severity of PTSD symptoms. All items are scored on a 0-4 scale. Higher score indicate worse severity	Time Frame: Baseline, week 5 and follow-up at 6 months
Secondary	Montgomery Åsberg Depression Rating Scale - Self-report (MADRS-S)	Change in depressive symptoms from baseline to post treatment and follow up (6 months). The Montgomery Åsberg Depression Rating Scale - Self-report (MADRS-S) is a 9 item self-report measure that assesses the presence and severity of depressive symptoms. All items are scored on a 0-6 scale. Higher score indicate worse severity.	Time Frame: Baseline, week 5 and follow-up at 6 months
Secondary	Euroqol, EQ-5D	Change in overall health from baseline to post treatment and follow up (6 months). EQ-5D is a standardised self-report measure of overall health status measured in terms of five dimensions; mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Mobility dimension asks about the person's walking ability. Self-care dimension asks about the ability to wash or dress by oneself, and usual activities dimension measures performance in "work, study, housework, family or leisure activities". In pain/discomfort dimension, it asks how much pain or discomfort they have, and in anxiety/depression dimension, it asks how anxious or depressed they are. The respondents self-rate their level of severity for each dimension using a three-level scale: 1 having no problems, 2 having some problems and 3 having extreme problems. A higher score indicate worse severity.	Time Frame: Baseline, week 5 and follow-up at 6 months
