DOES NEUROPSYCHOLOGICAL TEST-PERFORMANCE PREDICT RESUMPTION OF DRINKING IN POSTTREATMENT ALCOHOLICS

The prediction of resumption of drinking in posttreatment alcoholics was investigated as a function of five possible confounding variables: depression, anxiety, childhood symptoms of attention deficit and conduct disorders and family history of alcoholism. Male and female detoxified alcoholics (n = 103) in inpatient treatment programs were administered a neuropsychological battery and retested as outpatients 14 months later; peer nonalcoholics (n = 73), given the same battery, had a similar interest interval. Alcoholics who resumed drinking (N = 41) performed significantly poorer on an overall neuropsychological performance index than abstainers (N = 62) who performed significantly poorer than nonalcoholics. Stepwise multiple regression equations using the variables noted above revealed that depressive symptoms, ADD and the performance index were the only variables to enter the prediction (R2 = .26, p < .001); depression accounted for most of the variance. At retest all three groups improved significantly, but not differentially, and were as significantly different at retest as at initial testing. Implications of these results are discussed. © 1990.
