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 version 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：<./b> 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.
