Insomnia Coach

Functionality & Mechanism

Developed by the VA's National Center for PTSD, Insomnia Coach delivers a structured digital intervention grounded in Cognitive Behavioral Therapy for Insomnia (CBT-i). The system guides users through a five-week training plan that incorporates a personalized coaching feature, an interactive sleep diary to capture daily metrics, and 17 distinct tools designed to reinforce CBT-i principles. The interface facilitates the tracking of sleep patterns and the implementation of evidence-based strategies to improve sleep quality over time.

Evidence & Research Context

• A pilot randomized controlled trial (N=50) of military veterans with moderate insomnia evaluated the app's potential efficacy, feasibility, and acceptability over a six-week period.
• At post-treatment, a significantly larger proportion of the Insomnia Coach group (28%) achieved clinically significant improvement compared to the wait-list control group (4%).
• At the 12-week follow-up, the intervention demonstrated significant treatment effects for insomnia severity (d=-1.1), sleep onset latency (d=-0.6), and global sleep quality (d=-0.9).
• The study also established the app's feasibility and acceptability, with three-quarters of participants using the app for the full six weeks and reporting favorable perceptions.

Intended Use & Scope

This app is designed as a self-management tool for adults, including military veterans and servicemembers, experiencing symptoms of insomnia. Its primary utility is as an accessible public health intervention delivering CBT-i principles. The system is intended to augment, not replace, professional care; individuals with severe or complex symptoms should consult a healthcare provider.
