Summary

Researchers at the University of Tulsa are studying Exposure, Relaxation, and Rescripting Therapy (ERRT), a brief treatment for frequent trauma-related nightmares. The trial enrolls about 90 adults who have experienced trauma and have roughly one nightmare per week. Participants receive five to six weekly sessions of a modified ERRT, and the study examines how different components, such as exposure and relaxation, contribute to changes in nightmare frequency and sleep.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Exposure, Relaxation, and Rescripting Therapy (ERRT), a brief cognitive behavioral treatment for trauma-related nightmares
What this could lead to
If successful, this could clarify which components of ERRT matter most, potentially leading to shorter, more targeted treatments for trauma-related nightmares.
What could go wrong
This is a small case series, so results may not apply broadly. Some participants may not improve, and the study does not compare against a placebo or waitlist.
