Summary

Researchers at the University of Missouri-Columbia are studying whether improving insomnia can lead to better alcohol outcomes in heavy-drinking adults. The trial enrolls 256 adults who meet criteria for alcohol use disorder and insomnia disorder. Participants receive five weekly one-hour sessions of cognitive behavioral therapy for insomnia, a structured program that includes stimulus control, sleep restriction, and sleep hygiene. The study measures changes in insomnia severity, weekly drinking quantity, and alcohol-related consequences.

What this could mean

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

Active substance
Cognitive Behavioral Therapy for Insomnia (CBT-I), a structured sleep-focused talk therapy
What this could lead to
If CBT-I improves sleep and reduces drinking, it could offer a non-drug way to help heavy drinkers cut back by targeting insomnia.
What could go wrong
This is a behavioral trial, not a cure, and some participants may not stick with the therapy or see lasting changes in drinking. Sleep improvements do not always translate into less alcohol use.
