In the case–control sample, participants endorsed an average of 2.56 AAB criteria (s.d.=2.26; range=0–7). A total of 621 (45%) participants (468 males and 153 females) met criterion A for ASPD, defined by endorsement of three or more of the seven criteria. Males had higher AAB criterion counts than females (male mean=3.45, female mean=1.53; P<0.0001). Age was negatively associated with AAB criterion counts (r=−0.29, P<0.0001), indicating that older participants endorsed fewer lifetime AAB criteria. As expected, individuals classified as alcohol-dependent cases in the sample had higher AAB criterion counts (mean 3.8, s.d.=2.0) than those without alcohol dependence (mean 0.67, s.d.=0.96, P<0.0001).
