Efficacy of Digital Cognitive Behavioral Therapy for Insomnia (CBT-I) Utilizing Embodied Artificial Intelligence Agent in Virtual Reality: A Randomized Controlled Trial
The goal of this clinical trial is to evaluate whether a virtually embodied artificial intelligence (AI) agent delivered via VR-enhanced digital cognitive behavioral therapy for insomnia (dCBT-I) can improve insomnia outcomes and treatment adherence in adults with insomnia.
The main questions it aims to answer are:
- Does VR-enhanced dCBT-I with an embodied AI agent lead to greater improvements in insomnia symptoms compared to app-based dCBT-I with an AI chatbot at post-intervention and 3-month follow-up?
Researchers will compare VR-enhanced dCBT-I with an embodied AI agent to app-based dCBT-I with an AI chatbot to see if the VR-enhanced intervention results in significantly improved clinical outcomes and adherence.
Participants will:
- Be randomly assigned to either the VR-enhanced AI agent intervention group or the app-based AI chatbot control group
- Complete a digital cognitive behavioral therapy for insomnia (dCBT-I) program with either a virtually embodied AI agent (VR-based) or a chatbot-based application
- Undergo assessments at baseline, post-intervention, and 3-month follow-up

Kokeellinen: App-based dCBT-I with AI chatbot
Participants will receive digital cognitive behavioral therapy for insomnia through a mobile application featuring a text-based artificial intelligence chatbot, which capable of two-way interactive communication.
The chatbot will provide psychoeducation, behavioral strategies, cognitive techniques, and relaxation sessions throughout the intervention period.

|
Active Comparator: VR-enhanced dCBT-I with embodied AI agent
Participants will receive digital cognitive behavioral therapy for insomnia in a virtual reality environment.
The intervention will be delivered by a virtually embodied artificial intelligence agent capable of two-way interactive communication.
The embodied AI agent will provide the same therapeutic content as the app-based intervention, including psychoeducation, behavioral strategies, cognitive techniques, and relaxation sessions, while leveraging immersive virtual reality features to enhance user engagement and therapeutic interaction.
