Summary

This study tested a new 8-session psychotherapy called ChronoS in 67 adults with mood disorders (bipolar or depression) and chronic insomnia. The therapy focuses on sleep-wake awareness and habits. Researchers measured changes in insomnia severity using a standard questionnaire. The goal is to see if this talk therapy can ease sleep problems and improve mood.

What this could lead to
If it works, this could offer a non-drug option to improve sleep and mood in people with bipolar or depression.
What could go wrong
This is a small, completed study with no control group, so results may not be definitive. The therapy is new and not widely tested.
