Abstract

Objectives：This study was designed to develop the Korean version of Alcohol Use Disorders Identification Test (AUDITK)
and AUDIT Alcohol Consumption Questions (AUDIT-CK) which is composed of the first 3 questions of AUDIT, a screening tool for the alcohol use disorder.
Methods：The translation, including back translation procedure, was carried out, keeping the basic structure of AUDIT. AUDIT-K, AUDITC-K, Korean version of Michigan Alcoholism Screening Test (MAST-K), Korean version of CAGE (CAGE-K) and clinical diagnosis were administered to 43 alcohol use disorder patients and 43 non-alcohol use disorder control subjects. The reliability and validity of AUDIT-K and AUDIT-C-K were evaluated. The sensitivity and specificity for each cut-off point of AUDITK and AUDIT-C-K were calculated and the Receiver Operating Characteristic (ROC) curve analysis was done to get their optimal cut-off points. Diagnostic efficiency of AUDITK and AUDIT-C-K was evaluated by ROC curve analysis.
Results：AUDIT-K was found to have significantly high internal consistency, and test-retest reliability. The correlation
coefficients of AUDIT-K with MAST-K and CAGE-K were 0.86 and 0.80, respectively, and significant correlation was shown. Its optimal cut-off point was estimated as 12, and the sensitivity and specificity were 0.84 and 0.86, respectively. The correlation coefficients of AUDIT-C-K with MAST-K and CAGE-K were 0.60 and 0.56, respectively. Its optimal cut-off point was estimated as 8, and the sensitivity and specificity were 0.95 and 0.77, respectively. The ROC curve analysis indicated that the diagnostic efficiency of AUDIT-K and AUDIT-C-K was comparable with that of MAST-K and superior to that of
CAGE-K.
Conclusion：AUDIT-K and AUDIT-C-K have not only high reliability and validity, but also usefulness as a screening instrument for alcohol use disorder.
