Can an AI chatbot cure your sleepless nights?
NCT ID NCT06593262
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether an app that provides cognitive behavioral therapy for insomnia, enhanced with an AI chatbot, can help young people (ages 18-25) sleep better. Half of the 168 participants will use the app with the chatbot, and the other half will use the same app without it. The goal is to see if the chatbot makes the therapy more effective for reducing insomnia symptoms.
