Brief summary
The objective of this trial is to determine the effectiveness of an electronic cognitive behavioral therapy for insomnia (e-CBT-I) module in improving sleep and reducing alcohol use among heavy drinkers with insomnia. Specifically, it will test the effectiveness of Sleep Healthy Using the Internet (SHUTi), a well-validated version of e-CBT-I comprised of 6 weekly educational modules and daily sleep diaries. The rationale for this mixed methods proposal is that effective, nonpharmacologic treatments are necessary to stem the highly comorbid public health problems of alcohol use disorder (AUD) and insomnia. If successful, SHUTi will represent a novel and easily accessible intervention for reducing alcohol intake among high-risk heavy drinkers.
Interventions
BEHAVIORALWeb-Based Insomnia Education Program
Participants will be given access to a web-based program on sleep education to read at their own pace during the 9-week intervention period. The program content overlaps with SHUTi on the following topics: insomnia symptoms, impacts, and causes, basic sleep improvement strategies, and when to see a doctor. The information is akin to that found on WebMD or National Sleep Foundation website. Unlike the SHUTi program, the information is fixed, accessible immediately (no week-to-week information unlocking) and there are no customized bedtime or wake-time suggestions based on sleep diary data.
BEHAVIORALSHUTi Intervention
Sleep Healthy Using the Internet (SHUTi) is a well-validated version of e-CBT-I comprised of 6 weekly educational modules and daily sleep diaries. Participants will have 9 weeks to complete 6 once-weekly educational cores. Cores consist of: insomnia overview, sleep restriction, stimulus control, cognitive restructuring, sleep hygiene, and relapse prevention, and last approximately 45 minutes each. Participants will receive weekly objectives, as well as review and feedback on the previous core's assignments and sleep diary data, new material, assignments, and a summary. These features are supplemented with interactive features (i.e., personalized goal-setting, video vignettes). Participants receive daily emails prompting them to complete the 11-item sleep and alcohol use diary daily during the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Alcohol Use | 12 months (at baseline, 9 weeks, 3 months post-intervention, and 6 months post-intervention) | Alcohol use will be measured using the Timeline Follow Back (TLFB) calendar. Participants will report their drinking over the past 30 days. |
| Change in Insomnia | 12 months (at baseline, 9 weeks, 3 months post-intervention, and 6 months post-intervention) | Insomnia will be measured using the Insomnia Severity Index (ISI). This survey has 7 questions related to insomnia. Scores range from 0-28, with higher scores indicating increased insomnia. |
| Change in Sleep Quality | 12 months (at baseline, 9 weeks, 3 months post-intervention, and 6 months post-intervention) | Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). It measures seven areas (components): subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction. Scores range from 0-indefinite. A score greater than 5 is indicative of poor sleep quality. |
