Impulsiveness and compulsiveness in alcoholics and nonalcoholics

Impulsiveness and compulsiveness questionnaires were completed by recovering alcoholics (n = 54) and by a community sample (n = 351). No relationship was found, indicating these traits are independent, distinct constructs. Alcoholics scored significantly higher on impulsiveness than nonalcoholics, and impulsiveness was negatively associated with age for both groups. Interestingly, the significant difference between the two groups on impulsiveness was maintained across age groups. Alcoholic and nonalcoholic compulsiveness scores showed no difference: however, compulsiveness was negatively related to age in nonalcoholics, but not alcoholics. (C) 2000 Elsevier Science Ltd.
