were included in the alcohol and drug symptom count variables. All interview data were reviewed in a case conference consisting of at least two advanced graduate students in clinical psychology. Consensus between the diagnosticians regarding the presence or absence of symptoms was reached prior to assigning symptoms, referring to audio tapes of the interview when necessary. The consensus process yielded uniformly high diagnostic kappa reliabilities of .95 for adult antisocial behavior and > .91 for each substance use disorder.
