Two abuse criteria, hazardous use and legal problems, were excluded from the analysis due to their tautology with DUI status (i.e., arrest for DUI contributes to the legal problems criterion, and accident resulting from drinking and driving contributes to the hazardous use criterion). In order to determine whether arrest for DUI was simply a proxy for alcohol abuse (and thus did not index a group of individuals distinct from other individuals who met abuse criteria), we examined differences in alcohol and drug use and psychiatric disorder between individuals with DUIs and individuals who met abuse criteria but did not endorse arrest for DUI or accident due to drinking and driving.
