Objectives : To develop the Korean version of Severity of Dependence Scale for Alcohol drinkers (SDS-Alcohol-K) with the Korean population as a screening tool. Methods : Appropriate translation processes of SDS into Korean, including back translation process were performed. 50 alcohol dependence patients and 50 control subjects were recruited in this study. Korean ver-sion of SDS, AUDIT, CAGE and DSM-IV based diagnosis were administered. By using collected data, the reliability and validity of SDS-Alcohol-K were evaluated. Optimal cut-off points for alcohol dependence and hazardous drinking were determined by area under the Receiver Operating Characteristic (ROC) curve. Results : Data confirmed high internal consistency and test-retest reliability of SDS-Alcohol-K. Principal components analysis showed that the SDS-Alcohol-K scores lie on a single dimension. Pearson correlation coefficient of SDS-Alcohol-K with AUDIT and CAGE were 0.896 and 0.859, respectively, and significant correlation was shown. The optimal cut-off points selected were 4 for alcohol dependence and 2 for hazardous drinking. Conclusion : The results suggest that SDS-Alcohol-K is simple but valid and reliable tool for screening of alcohol dependence.
