Data from 7171 participants from the two studies were available for the analyses including 1879 African Americans, 4420 European Americans, and 872 American Indians. Within this sample, 1148 (16%) individuals met both CD and ASPD criteria, 1932 (27%) met adult ASPD but not CD (i.e., had AABS), 212 (3%) had CD only, and 3879 (54%) had at least one antisocial symptom but did not fit into any of the 3 diagnostic categories (ASPD, AASB, CD). Subsequent analyses focused only on the 3080 individuals in the two most prevalent diagnostic groups namely ASPD and AASB and their their demographic information is presented in Table 1. The two groups did not differ on the proportion of participants in the three racial groups or on the proportion with yearly incomes below $20,000; but those with ASPD were more likely to be male, younger, and have a lower level of education.
