Summary

The goal of this clinical trial is to test the preliminary efficacy of a brief mobile app targeting insomnia symptoms among veterans. In this study, we will enhance the mobile app, Insomnia Coach, with content from brief alcohol interventions to help veterans reduce both insomnia symptoms and alcohol use behaviors. We will compare those veterans who are randomly assigned to receive this brief mobile app intervention to those who receive a control condition. This will help us determine if veterans randomly assigned to receive the intervention experience greater improvement on outcomes compared to those who do not receive the intervention. The study involves a beta-test phase of the app to ensure feasibility and acceptability by veterans, followed by a randomized controlled trial with 130 veterans who meet criteria for insomnia and alcohol use disorder.

Conditions

• Alcohol Use Disorder
• Insomnia

Interventions

Type	Name	Description
BEHAVIORAL	Enhanced Insomnia Coach	The intervention combines the Insomnia Coach app with additional brief alcohol intervention to facilitate behavior change for both drinking behavior and insomnia symptoms. Insomnia Coach contains multiple components of CBT-I (e.g., stimulus control, cognitive restructuring, relaxation training, sleep hygiene/psychoeducation, monitoring of sleep via journals). The brief alcohol intervention content added to the CBT-I app is based on CBT skills for moderate drinking, delivered in a motivational enhancement style, and has demonstrated efficacy among young adults and veterans (e.g., correcting perceived norms, use of protective behavioral strategies, challenging expectancies).
BEHAVIORAL	Sleep hygiene comparator	Content is based on sleep hygiene practices, but without additional CBT-I content featured in the experimental condition. There is also not brief alcohol intervention content in the control condition.
