Table 2 summarizes the semistructured clinical interviews used to assess disorders. Fathers were interviewed about pre–age 15 symptoms of conduct disorder (CD), post–age 15 symptoms of antisocial personality disorder (i.e., the adult antisocial behavior or AAB syndrome), and nicotine, alcohol, and drug use disorders. Fathers were also asked about their age at first drink without parental permission and the maximum number of alcoholic drinks consumed in a 24-hr period. A drink was defined as being equivalent to a glass of wine, a bottle or can of beer, a shot glass of liquor, or a mixed drink.
