title: The role of antisocial, affective, and childhood behavioral characteristics in alcoholics' neuropsychological performance.
abstract: Chronic alcoholics demonstrate cognitive deficits when compared with nonalcoholics. These deficits are typically attributed to the direct effects of ethanol and its metabolites on the central nervous system (CNS). There are other factors, however, that differentiate alcoholics from controls, such as personality or behavioral characteristics. These factors may affect neuropsychological performance and thus alter the interpretation of alcoholic cognitive deficits as resulting solely from alcohol's toxic effects. To investigate this question, male and female alcoholics and peer nonalcoholic controls were compared on personality, behavioral, and cognitive measures. Alcoholics had greater numbers of antisocial behaviors, childhood behavioral disorder symptoms (CBD), and affective symptomatology, and had poorer neuropsychological performance than controls. The three personality and behavioral factors were positively intercorrelated with each other, and were negatively related to cognitive performance. The CBD factor proved to be the most consistent predictor of neuropsychological performance for both alcoholics and controls, and males and females. While the behavioral factors differentiated alcoholics from controls and predicted performance, significant differences between the groups in cognitive performance still remained when these factors were taken into account.
