Optimizing the US-AUDIT for alcohol screening in U.S. college students

ABSTRACTThis study examined cutoff scores on the new (2014) US-AUDIT (Alcohol Use Disorders Identification Test), adapted for U.S. standard drinks. No studies have examined optimal cutoff scores on the US-AUDIT for college students. 250 undergraduates (65% men) completed the US-AUDIT. At-risk drinkers reported at least four binge drinking episodes per week. Likely alcohol use disorder was assessed with a self-report diagnostic measure. Using the Youden method, the ideal cutoff to identify at-risk drinkers for the US-AUDIT was 5 for men (sensitivity = .93, specificity = .96) and 6 for women (sensitivity = .77, specificity = .86); and to identify likely alcohol use disorder was 13 for men (sensitivity = .69, specificity = .81) and 8 for women (sensitivity = .83, specificity = .80). Cutoffs were lower than the original AUDIT. Different US-AUDIT cutoffs for men and women should be used for likely alcohol use disorder, which may reflect differences in drinking quantity and frequency. Empirical guidelines for a...
