Conceptualizing and Measuring Weekend versus Weekday Alcohol Use: Item Response Theory and Confirmatory Factor Analysis
OBJECTIVE The purpose of the study was to determine whether students consume alcohol in greater quantities when drinking in celebration of an event or holiday versus typical drinking use. Celebratory occasions include tailgating during football games, holidays, and the beginning and ending of academic semesters. PARTICIPANTS Traditional undergraduates, ages 18 to 24, who attended the university full time in the Fall 2007 and the Spring 2008. METHODS Eight hundred participants were randomly selected to participate in the study. A stratified random sample was drawn according to class rank and sex. A total of 287 survey responses were collected. RESULTS Alcohol consumption was greatest during typical weekend drinking, followed by celebration drinking and then by typical weekday drinking. CONCLUSIONS Celebration drinking was expected to be greater than typical drinking; however, typical weekend drinking episodes were greates than celebratory drinking. Intervention efforts should focus on reducing weekend alcohol consumption.
