Data on lifetime psychiatric diagnoses and health service utilization were derived from the 2001—2002 National Epidemiologic Survey on Alcohol and Related Conditions, an epidemiological survey of 43,093 community-dwelling Americans age 18 and older conducted by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The NIAAA Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Edition (AUDADIS-IV) was used to generate psychiatric diagnoses. Individuals who met criteria for a lifetime psychiatric diagnosis based on AUDADIS-IV were then asked whether they ever went to a counselor, therapist, or physician; went to the emergency room; and were prescribed medications for the diagnosis in question.
