NCT ID NCT05622955
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a program called PEEPS for people with endometriosis-related pelvic pain. Over eight weekly sessions, participants learned about mindfulness, yoga, nutrition, and pain coping strategies, while getting support from peers and clinicians. The goal was to see if the program could reduce pain interference and improve quality of life. The study included 35 adults with confirmed endometriosis and chronic pelvic pain.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Peer Empowered Endometriosis Pain Support (PEEPS) program
- What this could lead to
- If it works, this could offer a non-drug, supportive approach to help people with endometriosis better manage chronic pelvic pain and improve daily life.
- What could go wrong
- This is a small pilot study with only 35 participants and no control group, so results may not apply broadly. The program requires weekly in-person attendance, which may not be feasible for everyone.
