Note. CCD = a history of childhood conduct disorder; AD = a history of alcohol dependence; CCD-alone = CCD without AD; AD-alone = AD without CCD. Lifetime problems with alcohol, marijuana, and other drugs are based on the number of positive responses to subsets of questions on the respective sections of the SSAGA. Other drug lifetime problems represent a total of problems with cocaine, other stimulants, opiates, sedatives, or other substances, such as hallucinogens, and inhalants. Conduct problems are positive responses to those questions assessing childhood conduct disorder. Adult antisocial problems are positive responses to the questions assessing antisocial personality. All values represent averages for entire sample within each group. Included in the group percentages of Antisocial Personality Disorder are participants that met DSM-IV diagnostic criteria for adult antisocial personality disorder.
