국내 음주자들을 대상으로 한 한국어판 의존 심각도 척도(Severity of Dependence Scale-Alcohol, SDS-Alcohol)의 신뢰도, 타당도 및 절단점

Reliability, Validity and Optimal Cut-Off Points of the Korean Version Severity of Dependence Scale (SDS) in a Korean Sample of Alcohol Drinkers

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.
