Summary

This study tests a new digital app called Stellar Sleep, which provides cognitive behavioral therapy for insomnia (CBT-I) online. It aims to help people with insomnia improve their sleep by using a smartphone or computer, and it can automatically upload sleep data from wearable devices like FitBits. The study involves 60 adults and measures changes in insomnia severity over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Web-based Cognitive Behavioral Therapy for Insomnia (Stellar Sleep app)
What this could lead to
If it works, this could provide an accessible, low-cost digital treatment for insomnia, helping people who can't get in-person therapy.
What could go wrong
This is a small pilot study with only 60 participants, so results may not apply to everyone. The app may not work as well as in-person therapy.
