Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

written exposure therapy

The treatment consists of written exposure therapy (WET), which is manualized trauma-focused CBT in five sessions over 5 weeks.

Group Type EXPERIMENTAL

WET

Intervention Type BEHAVIORAL

The manual is based on established CBT interventions in trauma such as exposure. In short, the treatment is that the participant should be able to approach their intrusive memories and by doing this repeatedly, the memory will give rise to less discomfort.
