Comparison of the Alcohol Dependence Scale and diagnostic interview schedule in homeless women.

The Alcohol Dependence Scale (ADS) is a 25 item self-report instrument designed to evaluate the degree of severity of alcohol dependence. Although previous studies have reported on the validity of the ADS, no studies using the ADS have been done on the homeless population, a special and rapidly growing population. To assess the utility of the ADS in a population of homeless, substance-abusing women, the ADS questionnaire was compared with the DSM-III-R alcohol use disorder diagnosis as measured by the Diagnostic Interview Schedule (DIS). Both the ADS and the DIS were administered to 149 homeless, substance-abusing women by trained, lay interviewers. There was good agreement between the ADS and the past-year DIS diagnosis of alcohol use disorder. The level of agreement between the ADS and DIS, as well as sensitivity and specificity, for various ADS cutoff scores are reported to facilitate selection of cutoff scores by clinicians and future researchers.
