In this article, we compare problem severity and adult antisocial behavior among three groups of cocaine- or alcohol-dependent patients: those with antisocial personality disorder (APD), those who met adult but not childhood APD criteria (A-APD), and those who met neither (non-APD) in order to determine the clinical utility of the A-APD category. Subjects were 269 male veterans admitted for substance abuse treatment. The Addiction Severity Index was used to determine problem severity and the NIMH Diagnostic Interview Schedule was used to obtain positive DSM-III APD criteria and APD diagnoses. More APD subjects reported arrests, illegal behavior, and chronic lying than A-APD and non-APD subjects. On several variables (recent family/social problems, trouble controlling violent behavior, and time incarcerated), A-APD subjects were intermediate in severity. Overall, the non-APD subjects had the least severe problem status. When the APD and A-APD groups were equated on number of positive adult APD criteria, the only differences that consistently remained were difficulty controlling violent behavior and commission of criminal acts, which were endorsed more frequently in the APD group. It appears that the unique contribution of the early onset criteria for the APD diagnosis is that it identifies individuals more likely to engage in criminal and violent behavior. The more general irresponsibility and disregard for the rights of others characteristic of APD is equally evident in both antisocial groups. This work indicates that the APD versus non-APD distinction may not be fine grained enough for clinical or research purposes.
