A review of psychologically oriented treatment of alcoholism. II. The relative effectiveness of different treatment approaches and the effectiveness of treatment versus no treatment.

A review of 384 studies of psychologically oriented alcoholism treatment showed that differences in treatment methods did not significantly affect long-term outcome. Mean abstinence rates did not differ between treated and untreated alcoholics, but more treated than nontreated alcoholics improved, suggesting that formal treatment at least increases an alcoholic's chances of reducing his drinking problem.
