Summary

Researchers are testing whether cognitive behavioral therapy for insomnia (CBT-I) can help returning veterans who drink heavily. The trial enrolls veterans deployed after September 11, 2001, who have insomnia and at least one heavy drinking episode in the past month. Participants receive five to six weekly one-hour sessions of CBT-I. The study measures changes in insomnia symptoms, sleep quality, 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 talk therapy delivered in weekly one-on-one sessions
What this could lead to
If CBT-I reduces heavy drinking, it could offer a non-drug way to help veterans cut back on alcohol by first fixing their sleep.
What could go wrong
This is a small study of 71 veterans, so results may not apply to everyone. CBT-I requires weekly sessions and may not work for people with certain sleep or mental health conditions.
