Differences between essential and reactive alcoholics on tests of neuropsychological functioning and affect

Abstract

This study tested the hypothesis that Essential Alcoholics (n = 15) develop a more severe form of alcoholism than Reactive Alcoholics (n = 12). VA alcoholic patients were classified as Essential or Reactive Alcoholics, using the Rudie-McGaughran questionnaire, and tested on four neuropsychological tests, the Neuropsychological Impairment Scale, the Beck Depression Inventory, Tarter's Hyperactivity/Minimal Brain Dysfunction questionnaire, and Latcham's Measure of Antisocial Behavior. While the two groups did not differ in age, education, or Family History of alcoholism. Essential Alcoholics had an earlier age of onset and a longer chronicity of alcoholism. After analysis of covariance was used to control for group differences in age of onset and chronicity, Essential Alcoholics were still significantly higher on depression and significantly more impaired on five subtests of the Neuropsychological Impairment Scale: global measure, total items, general, learning-verbal, and frustration. Nonsignificant group differences, in the expected direction, were found for the Shipley Mental Age and Tarter's questionnaire. These results suggest that Essential Alcoholics have higher depression scores and greater impairments in neuropsychological functioning than Reactive Alcoholics.
