Effects of digital cognitive–behavioral therapy for insomnia in heavy drinkers with insomnia: A replication and extension study.
Abstract
= 52). Participants completed assessments immediately following the intervention period (9 weeks) and again at 3- and 6-months postintervention. Linear mixed-effects models showed that those in the SHUTi condition reported significantly greater improvements in sleep and greater reductions in drinking frequency relative to the PE condition. Additionally, those in the SHUTi condition reported greater reductions in depression symptoms and sleep medication use relative to the PE condition. Limitations include relatively high attrition, reliance on self-report measures, and demographic homogeneity. These findings replicate and extend the pilot trial results and support the utility of incorporating sleep interventions into alcohol use disorder prevention and treatment efforts.
