Summary

Alcohol use disorder (AUD) inflicts enormous physical, emotional, and financial burdens on the individual and society at large. Insomnia is highly prevalent among individuals with AUD, and disrupted sleep contributes substantially to alcohol-related problems. While research suggests that treating insomnia may effectively reduce AUD, the degree to which treating insomnia in heavy drinkers reduces alcohol consumption and prevents the onset of severe AUD is not known. This study will be the first to evaluate an Internet-based version of cognitive behavioral therapy for insomnia (CBT-I) in community-dwelling, heavy drinking adults with insomnia. Sleep Healthy Using the Internet (SHUTi), the most widely-used and well-validated version of Internet-based CBT-I will be used. The primary aim is to reduce alcohol consumption and insomnia severity in this population.
