Abstract
The authors examined the relationship between global sleep quality and alcohol risk, including the extent to which global sleep quality moderated the relationship between alcohol use and drinking-related consequences. Global sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) and alcohol-related consequences were assessed using the Rutgers Alcohol Problem Index (RAPI). The sample consisted of 261 college students (61.3% female, 58.2% Caucasian) who completed online surveys. Using a four-step hierarchical multiple regression model, global sleep quality was found to predict alcohol consequences, over and above assessed covariates (demographics and weekly drinking). Further, global sleep quality emerged as a strong moderator in the drinking-consequences relationship such that among heavier drinkers, those with poorer global sleep quality experienced significantly greater alcohol-related harm. Campus health education and alcohol interventions may be adapted to address the importance of maintaining a healthy lifestyle, both in terms of healthful sleeping and drinking behaviors, which appear to play a strong synergistic role in alcohol-related risk.
