Table 3.

Contingency Table of Diagnostic Status. Table is ordered first by the number of comorbid disorders. Within a value for the number of comorbid disorders (e.g., 2 disorders), the entries are ordered by frequency of observation within the adolescent sample. Ties are broken by the frequency within the parent sample. Values within the Adolescents and Parents columns are computed only for participants with no missing data. Note that the counts among adolescents with missing observations of AB are displayed. Counts for adults with missing data are not displayed for lack of space. The column of adolescents missing AB contains counts for adolescents missing a value for AB who display that particular pattern of disorder. AB = Adult Antisocial Behavior; CD = Conduct Disorder; AD = Alcohol Dependence; MD = Marijuana Dependence; DD = Drug Dependence.
