Summary

This study compares two ways of delivering digital cognitive behavioral therapy for insomnia (dCBT-I): one uses a standard app with an AI chatbot, the other uses a virtual reality (VR) environment with an embodied AI agent. Adults with insomnia are randomly assigned to one of the two groups and complete the therapy program. The goal is to see if the VR-enhanced version leads to better sleep outcomes and higher treatment adherence.

What this could lead to
If it works, this could offer a more engaging and effective digital therapy for insomnia, potentially improving sleep without medication.
What could go wrong
This is a relatively small trial comparing two digital approaches, so results may not apply to everyone. The VR component may cause discomfort or be less accessible for some users.
