A brief cognitive behavioral therapy for insomnia (CBT-I) delivered via a mobile app significantly improved sleep quality and reduced insomnia severity in adults with chronic insomnia. Participants using the app showed moderate to large improvements in sleep efficiency, total sleep time, and time to fall asleep compared to a control group. The app-based treatment also reduced maladaptive sleep-related beliefs. These gains were maintained at a one-month follow-up, suggesting that digital CBT-I can be an effective and accessible treatment option for chronic insomnia.
