Can cramming PTSD therapy into a few weeks help veterans cut substance use?
NCT ID NCT06296186
First seen Aug 27, 2026 · Last updated Aug 28, 2026 · Updated 1 time
Summary
This trial tests whether giving prolonged exposure therapy for PTSD in a massed format, with multiple sessions each week, works as well as the standard once-a-week schedule for veterans who are also in intensive outpatient treatment for substance use disorder. Researchers will compare PTSD symptom severity, substance use, and therapy completion rates between the two schedules. The goal is to see if a more intensive therapy schedule can help veterans benefit from PTSD treatment while they are also working on reducing substance use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Prolonged Exposure Therapy, a type of talk therapy for PTSD, given in a massed format with multiple sessions per week
- What this could lead to
- If it works, this could offer a faster, more practical way to deliver PTSD therapy to veterans who are also in substance use treatment, potentially improving both PTSD symptoms and substance use outcomes.
- What could go wrong
- This is a behavioral therapy trial, so results depend on participant engagement and therapist delivery. The massed format may be too intense for some, and the trial's findings may not apply to all veterans or treatment settings.
