NCT ID NCT07782268
First seen Aug 24, 2026 · Last updated Aug 25, 2026 · Updated 1 time
Summary
This trial tests whether a brief therapy called Written Exposure in Substance Treatment (WEST) can reduce PTSD symptoms in people staying at a residential substance use program. Participants with PTSD are randomly assigned to receive WEST plus usual care or usual care alone. The study measures changes in PTSD symptoms, substance use, and mental health outcomes before and after the intervention.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Written Exposure Therapy (WEST), a brief 5-session behavioral therapy involving guided writing exercises to reduce PTSD symptoms
- What this could lead to
- If effective, this brief therapy could become a practical tool to reduce PTSD symptoms and improve substance use outcomes in residential treatment programs.
- What could go wrong
- The therapy is being tested in a specific residential setting, and results may not generalize. It is an early-stage adaptation, and benefits over usual care are not yet established.
