Failure to find differences in drinking behavior as a function of familial risk for alcoholism: a replication.

Groups of high-risk (alcoholic fathers), middle-risk (second-degree alcoholic relatives) and low-risk (no first- or second-degree alcoholic relatives) male college students were compared with respect to drinking behavior, sociodemographic variables, personality, cognitive functioning, and mental health and drug use problems in themselves and in family members. The groups differed significantly on only one of a number of sociodemographic variables. No significant group differences were revealed in drinking behavior, or alcohol-related symptoms or consequences. High-risk subjects reported significantly more childhood attentional and social problems than did low-risk subjects. No group differences were found with respect to other childhood problem behaviors, cognitive functioning, subject or family drug use, or mental health problems. The findings are discussed in terms of the questions they raise concerning the results of high-risk studies and the contribution of genetic factors to alcoholism.
