The three AUDIT-C questions are: 1) How often do you have a drink containing alcohol? (Choices: never, monthly or less, 2-4 times a month, 2-3 times a week; or 4 or more times a week). 2) How many standard drinks containing alcohol do you have on a typical day? (Choices: 1 or 2; 3 or 4; 5 or 6; 7 to 9; or 10 or more). 3) How often do you have six or more drinks on one occasion? (Choice: never; less than monthly; monthly; weekly; daily or almost daily). Responses to each question are assigned 0-4 points, yielding a total score of 0-12. AUDIT-C screening thresholds that maximize sensitivity and specificity for detecting unhealthy alcohol use are ≥4 in men and ≥3 in women, with the likelihood in both sexes of alcohol-related harm increasing as AUDIT-C scores increase (Bradley et al., 2007, Bush et al., 1998).
