title: The Chinese version of the Addiction Severity Index (ASI-C): reliability, validity, and responsiveness in Chinese patients with alcohol dependence.
abstract: We evaluated the reliability, validity, and responsiveness of the Chinese version of the 5th edition Addiction Severity Index (ASI-C-5) in Chinese male alcohol-dependent inpatients. Three hundred and fifty-four inpatients with alcohol dependence from five regions of China were interviewed in person by five trained interviewers using the ASI-C-5. Responses were then analyzed for internal consistency reliability, discriminant validity, criterion validity, and responsiveness. Forty subjects were re-interviewed 7 days later to assess test-retest reliability. The ASI-C-5 had good internal consistency, with an overall standardized Cronbach's alpha of 0.79. The Cronbach's alpha values for internal consistency of domain CSs ranged from 0.48 to 0.95, and were above 0.60 for six domains. The 7 day test-retest reliability was acceptable as evidenced by high Pearson correlation coefficients (0.75-0.92, p < 0.01) for 6 of 7 domain CSs. Correlation coefficients between the seven domain CSs ranged from 0.007 to 0.390 (p < 0.05 or 0.01 two-sided), indicating strong discriminant validity. The correlation coefficient between the alcohol dependence composite score of ASI-C-5 and the Alcohol Use Disorders Identification Test (AUDIT) was 0.69 (p < 0.01), indicating good criterion validity. The frequency of extreme scores was low, except for significant floor effects in the "Drugs" and "Legal Status" domains. Collectively, these findings suggest that the ASI-C-5 exhibited strong reliability, validity, and responsiveness in Chinese male alcohol-dependent inpatients.
