Abstract

ObjectiveSleep disturbance is widespread among individuals with alcohol use disorder (AUD) and is thought to reduce the capacity for self-regulation. The present study examines how sleep disturbance is associated with the regulation of tonic (i.e., “trait-like”) and cue-induced (i.e., “provoked”) craving, among individuals with AUD. MethodsParticipants with an AUD (N = 58) completed the Pittsburgh Sleep Quality Index (PSQI) for sleep quality, the Obsessive-Compulsive Drinking Scale (OCDS) for tonic craving, and the Alcohol Urge Questionnaire (AUQ) for cue-induced craving during an alcohol cue-exposure paradigm. A series of hierarchical regressions examined the independent contribution of sleep quality to tonic and cue-induced alcohol craving. ResultsPSQI global score was associated with tonic craving per the OCDS, over and above alcohol use and demographic measures. PSQI global score was not associated with cue-induced craving. ConclusionThese findings suggest that sleep dysfunction plays a role in tonic alcohol craving and that the underlying mechanism may be the reduction of self-regulation. Treatments targeting sleep dysfunction in AUD may prove useful in reducing craving and overall alcohol use.
