Table 2 shows comparison of prevalence rates of externalizing (EXT) disorders, which includes DSM-IV lifetime diagnosis for SUD (dependence/abuse) and other related disorders, such as anti-social personality disorder (ASPD), conduct disorder (CD), attention deficit hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD). “Other drugs” refers to the substances other than those mentioned in the list. Significant differences in the prevalence rates between LR and HR subjects were observed in several diagnoses for all three comparisons: (i) Males: alcohol, tobacco, marijuana, CD, any SUD, and any EXT; (ii) Females: alcohol, tobacco, marijuana, stimulant, other drugs, any SUD, and any EXT; and (iii) All subjects: alcohol, tobacco, marijuana, cocaine, stimulant, opiate, other drugs, CD, ODD, any SUD, and any EXT. The diagnoses that were significant in all the comparisons were: alcohol, tobacco, marijuana, any SUD, and any EXT.
