Alcoholic subtypes and the MacAndrew Alcoholism Scale

Forty-five alcoholics in treatment (29 males and 16 females) who reported substantial alcohol dependence but scored in the nonalcoholic range on the MacAndrew Alcoholism Scale (MAC) were matched with 45 alcoholics who reported a similar degree of alcohol dependence and obtained alcoholic-range scores on the MAC. Results reveal that high MAC alcoholics were characterized by gregariousness, social drinking, belligerence and aggression while drinking, and a high degree of alcohol-related legal problems. Low MAC alcoholics appeared to be a different or less distinctive type of alcoholic; although they were less outgoing and preferred not to drink with others, they experienced a wide range of serious alcohol-related consequences. Low MAC alcoholics were not more likely to have a history of nonsubstance use psychiatric diagnosis and treatment. Cloninger, Bohman, and Sigvardsson's (1981) alcoholic typology was related to MAC scores: There was a greater likelihood that high-MAC alcoholics were Type II and low MAC alcoholics Type I.
