NCT ID NCT07180290
First seen Jun 26, 2026 · Last updated Jun 26, 2026
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.
