Abstract

OBJECTIVES: This study is to examine the efficacy and the limitation of translated Korean version of the Obsessive-compulsive Drinking Scale. The Korean version of the scale is to be used for treatment and research on alcoholism.
METHODS
This study was carried out to examine reliability and validity of the translated Korean version of the Obsessive-compulsive Drinking Scale. One hundred forty two out-patient alcohol dependence subjects were measured of their cognitive and behavioral aspects of craving with this scale.
RESULTS
For 142 tested alcoholic subjects, internal consistency among 14 items of the Obsessive-compulsive Drinking Scale was 0.8947(Crohnbach's alpha). For 40 detoxified alcoholics, test-retest reliability of total score of the Korean version of the Obsessive-compulsive Drinking Scale was 0.76 (correlation coefficient, p<0.01). In 131 alcoholic subjects, validity of total score of the Korean version of the Obsessive-compulsive Drinking Scale was examined by correlation analysis with visual analogue scale (VAS). Correlation coefficient was 0.52 with VAS. Especially, correlation coefficient of compulsive subscale of the Korean version of the Obsessive-compulsive Drinking Scale was 0.61 with VAS. The total score of the Korean version of the Obsessive-compulsive Drinking Scale which was analyzed by repeated measure analyses of variance during 8 weeks was significantly different between the relapse group and the abstinence group.
CONCLUSION
The Korean version of the Obsessive-compulsive Drinking Scale shows very similar psychometric performance to the original Obsessive-compulsive Drinking Scale developed by Anton. The Korean version, therefore, is an useful instrument that reflects characteristic drinking behaviors of alcoholics.
