Data was collected using the National Institute on Alcohol Abuse and Alcoholism Alcohol - Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV (AUDADIS-IV), (Grant et al., 2001a), version Wave 2 (Grant et al., 2004a). The AUDADIS-IV is a structured diagnostic interview, developed to advance measurement of substance use and mental disorders in large-scale surveys (Grant et al., 2008; Grant et al., 2004e). Computer algorithms produced DSM-IV diagnoses based on AUDADIS-IV data collected at Wave 1 (prevalence cases) and Wave 2 (incident cases between Wave 1 and Wave 2).
