The study population was selected from a database of convicted DWI offenders who were referred to the Lovelace Comprehensive Screening Program (Screening Program) between April 1989 and March 1992. To qualify for inclusion in the present analysis, participants must have completed both a 5- and 15-year follow-up interview and must have met Diagnostic and Statistical Manual of Mental Disorders–Fourth Edition (DSM-IV) criteria for an alcohol- or drug-use disorder, with an age of onset equal to or less than the age at the time of referral to the Screening Program.
