AUDIT: total score. Drinks: number of standard drinks; Dose: milliliters of absolute alcohol per kilogram of body weight; BAC: calculated blood alcohol concentration mg/dl; Duration: length, in hours, of a drinking occasion; Frequency: number of drinking occasions per week; History: period since onset of regular alcohol use in months; Body weight in kg. At-risk status determined by AUDIT cut-scores of 8+/6+ (men/women). Group differences based on independent samples t tests
