![]() Understanding diagnostic tests 3: receiver operating characteristic curves. ![]() Conclusions: The reliability and validity of the AUDIT-C are high, indicating that it is useful for identifying alcohol use disorders or risky drinking among the general population in Japan, a group at high risk of cancer development. The appropriate cutoffs for identifying risky drinking were the same for both genders. With higher scores on the AUDIT, the specificity decreased and false-positives increased. Results: The reliability of the AUDIT-C score was high ( $16$ points on the AUDIT were 0.93 and 0.80, respectively, for men (LR+=4.7) and 0.92 and 0.98, respectively, for women (LR+=55.6). The k coefficient, Cronbach's coefficient alpha, Spearman's correlation coefficient, and intraclass correlation coefficient (ICC) were determined and the validity of the AUDIT-C was analyzed using the data from a nationwide survey on adult alcohol use conducted in 2008 (n=4,123). Materials and Methods: A test-retest method was applied with a 2-week interval with 113 health care employees. To assess the reliability and validity of the Alcohol Use Disorders Identification Test - Consumption (AUDIT-C) for detecting alcohol use disorders or risky drinking in Japanese adults the present study was conducted. Background: Alcohol is well established as a risk factor for cancer development in many organ sites. ![]()
