First seen Jun 27, 2026 · Last updated Jun 30, 2026 · Updated 2 times
Summary
This study compares a shorter therapy focused on guilt (TrIGR) to a standard PTSD therapy (CPT) in 160 U.S. Veterans. The goal is to see if TrIGR is no less effective at reducing PTSD, depression, and guilt symptoms. Participants are randomly assigned to one of the two treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Trauma Informed Guilt Reduction Therapy (TrIGR) and Cognitive Processing Therapy (CPT)
- What this could lead to
- If TrIGR works as well as CPT, it could offer a shorter, less resource-heavy option for treating PTSD in Veterans.
- What could go wrong
- This is a non-inferiority trial with 160 participants, so results may not apply to all Veterans. The therapy is behavioral, so individual responses vary.
