Validity of the AUDIT-C screen for at-risk drinking among students utilizing university primary care

Objective: Research is needed to establish the psychometric properties of brief screens in university primary care settings. This study aimed to assess the construct validity of one such screen, the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), for detecting at-risk drinking among students who have utilized on-campus primary care. Participants: 389 students recently seen in university primary care completed a confidential online survey in December 2014. Methods: Bivariate correlations between the AUDIT-C and measures of alcohol consumption and negative drinking consequences provided concurrent evidence for construct validity. Receiver Operating Characteristic curve analyses determined optimal cut-off scores for at-risk drinking. Results: The AUDIT-C significantly correlated with measures of alcohol consumption and negative drinking consequences (p < .001). Analyses support optimal AUDIT-C cut-off scores of 5 for females and 7 for males. Conclusions: The AUDIT-C is a valid screen for at-risk drinking among students who utilize university primary care.
