Alcohol use disorder(AUD) is a leading cause of death in the USA. Outcomes may be improved by treatment that focuses on symptoms which predict relapse during early sobriety, including insomnia, shown to be an independent predictor of relapse in adults with AUD. However, no existing AUD treatments specifically target the effects of insomnia during early sobriety. Prior research demonstrates that cognitive behavioral therapy for insomnia(CBTi) improves daytime and sleep symptoms, which may be beneficial for adults seeking AUD treatment. However, there has been less focus on the effects of CBTi on drinking behavior and relapse. This study aims to investigate the impact of two interventions, CBTi and Sleep Hygiene Education(SHE) on drinking behaviors, sleep, and daytime insomnia symptoms. One hundred fifty participants aged 18-65 were recruited from the University of Michigan Addiction Treatment Services as they entered AUD treatment. Before enrollment, participants met eligibility criteria, including meeting the DSM-5 criteria for both AUD and chronic insomnia. These diagnoses were confirmed using the Alcohol Use Disorders Identification Test(AUDIT) and Insomnia Severity Index(ISI), with minimum scores required for enrollment. As participants enrolled, they were randomized to one of two interventions: CBTi or SHE, both delivered via telemedicine. CBTi is a widely used evidence-based intervention for chronic insomnia, involving various therapeutic interventions targeted at improving sleep related behaviors and cognitions. SHE focuses on delivering in-depth education about sleep hygiene and the impacts of substance use on sleep. Both interventions included keeping an online sleep diary to monitor subjective symptoms of insomnia. Those who suffer from AUD are prone to relapse or developing secondary addictions, which necessitates the development and implementation of non-pharmaceutical treatments. The anticipated results include a demonstrated overall improvement in insomnia and a lowered quantity of alcohol consumption, indicated by fewer participant-reported episodes of alcohol consumption.
