The alcohol use disorders identification test: reliability study of the Japanese version

Alcohol abuse is recognized as a major health issue, and early detection of alcohol abuse is very important. The alcohol use disorders identification test (AUDIT) has been widely used as a specific tool for its detection. We conducted a cross-sectional survey of Japanese male workers to validate the Japanese version of this test. The Japanese version of AUDIT also contains 10 questions. A score greater than or equal to 11 was considered as indicative of serious alcohol abuse or dependence. A total of 168 subjects took part in the survey, and 145 of these subjects sent in their responses to the questionnaire. Among these 145 subjects, there were 136 men. The average age of these male subjects was 38.2 years (+/- 9.9). Among the 136 male subjects, 113 returned completely filled-in questionnaires. There were no significant differences in the mean values of the AUDIT score, short version of AUDIT (AUDIT-C) score, or age between the subjects who did or did not indicate: their names in the questionnaire. The internal reliability (Cronbach alpha) of AUDIT was 0.67 for the total subject population and 0.45 for the subjects who indicated their names in the questionnaire (n = 69). Cronbach's alpha of AUDIT-C was 0.51 for the total subject population and 0.43 for the subjects who indicated their names in the questionnaire. The Spearman's rho between AUDIT and AUDIT-C was 0.92 (P < .01), and the percentage of subjects with an AUDIT score greater than or equal to 11 was 8.0% (9/113). Thus, the Japanese version of AUDIT showed satisfactory internal reliability. AUDIT is easy to use and is useful for the detection of alcohol-related problems in occupational workers.
