Abstract
Previous studies have indicated that alcoholics report a high frequency of problem behaviors in childhood. Additionally, certain neuropsychological deficits are often evident. Both childhood problem behavior and antecedent neuropsychological deficits have been suggested as risk factors for the later development of alcoholism. However, neither set of variables nor their interrelationship have been previously investigated in a sample at high risk for the development of alcoholism. In this study, unaffected offspring of an alcoholic parent and unaffected offspring of nonalcoholic parents were examined. Although attention deficit disorder/ hyperactivity and conduct disorder prior to age twelve predicted the onset of drinking, the frequency of childhood behaviors was similar in both groups. Further, the neuropsychological performances of the highrisk and low-risk samples were also similar and within normal limits. The theoretical and methodological implications of these findings for future research are discussed.
