Brief Summary

Insomnia is major problem among Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) Veterans. Insomnia impacts physical and mental health functioning and is associated with reduced quality of life. Cognitive Behavioral Therapy for Insomnia (CBT-I) is one of the most promising treatments for insomnia; however, access to CBT-I is severely limited by a lack of trained clinicians within the Veterans Health Administration (VHA) and Department of Defense (DoD). There is a critical need to offer innovative approaches to meet the demand and need for insomnia treatment. Leveraging technology to meet treatment demands is consistent with service delivery models based upon stepped care principles. This randomized controlled trial will determine whether a computerized, self-guided, web-based version of CBT-I is efficacious in reducing insomnia symptoms and improving functioning compared to a computerized program control.

Arm && Interventions

Group	Intervention	Description
Computerized Intervention 1	Computerized Cognitive Behavioral Therapy for Insomnia	A web-based program will deliver components of CBT-I on a time and event-based schedule. Pre and Post-Intervention assessments will be administered to determine the efficacy of the intervention.
Computerized Intervention 2	Sleep Education	A web-based program will deliver components of sleep education via an Internet platform. Pre and Post-Intervention assessments will be administered to determine the efficacy of the intervention.

Primary Outcome Measures

Name	Time	Method
Change in Insomnia Symptom Severity as Measured by the Insomnia Severity Index	Baseline and 9 Weeks	The primary analyses will be the intent-to-treat comparison between groups of the change in insomnia symptom severity as measured by the ISI from Time 1 to Time 2. Statistical inference regarding the difference between intervention groups will be based on the estimated coefficient for a group indicator variable in each of three analysis of covariance models with the change from Time 1 to Time 2 for each outcome serving as the dependent variable. Additional covariates will include the baseline value of the outcome to improve precision of the estimate, and any potential confounders discovered in the randomization check.
Maintenance of Change in Insomnia Symptom Severity as Measured by the Insomnia Severity Index at 6-months and 1-Year Post-Intervention	Baseline, 6-Months and 1-Year	A similar analysis will be performed for the above noted insomnia severity outcome on the change from Time 1 to Time 3 and to Time 4 to determine persistence of group differences to six-months and one-year post-intervention.

Secondary Outcome Measures

Name	Time	Method
Change in Physical Health and Mental Health Functioning as Measured by the Veteran's SF-36	Baseline and 9 Weeks	A similar analysis will be performed with physical health and mental health functioning as the outcomes, based on self-reported responses to the Veteran's SF-36 measure.
Maintenance of Change in Physical Health and Mental Health Functioning as Measured by the Veteran's SF-36 at 6-months and 1-Year Post-Intervention	Baseline, 6-Months and 1-Year	A similar analysis will be performed for the above noted outcomes on the change from Time 1 to Time 3 and to Time 4 to determine persistence of group differences to six-months and one-year post-intervention.
