Abstract
Background: This study evaluated the utility of the Alcohol Use Disorders Identification Test Alcohol Consumption Questions (AUDIT-C) in screening at-risk drinking and alcohol use disorders among Korean college students. Methods: For the 387 students who visited Chungnam National University student health center, drinking state and alcohol use disorders were assessed through diagnostic interviews. In addition, Alcohol Use Disorders Identification Test (AUDIT), AUDIT-C, and cut down, annoyed, guilty, eye-opener (CAGE) were applied. The utility of the questionnaires for the interview results were compared. Results: The areas under the receiver operating characteristic curves (AUROCs) of AUDIT-C for screening at-risk drinking were 0.927 in the male and 0.921 in the female participants. The AUROCs of AUDIT and CAGE were 0.906 and 0.643, respectively, in the male, and 0.898 and 0.657, respectively, in the female participants. The optimal screening scores of at-risk drinking in AUDIT-C were ${\geq}6$ in the male and ${\geq}4$ in the female participants; and in AUDIT and CAGE, ${\geq}8$ and ${\geq}1$, respectively, in the male, and ${\geq}5$ and ${\geq}1$ in the female participants. The AUROCs of AUDIT-C in screening alcohol use disorders were 0.902 in the male and 0.939 in the female participants. In the AUDIT and CAGE, the AUROCs were 0.936 and 0.712, respectively, in the male, and 0.960 and 0.844, respectively, in the female participants. The optimal screening scores of alcohol use disorders in AUDIT-C were ${\geq}7$ in the male and ${\geq}6$ in the female participants; and in AUDIT and CAGE, ${\geq}10$ and ${\geq}1$, respectively, in the male, and ${\geq}8$ and ${\geq}1$ in the female participants. Conclusion: AUDIT-C is considered useful in screening at-risk drinking and alcohol use disorders among college students.
