A group of 122 mostly male, White alcoholic patients admitted to short-term hospital treatment programs participated in this study.
In the 18 months following treatment, the more days the patient attended Alcoholics Anonymous self-help meetings, the longer their abstinence lasted.
AA meeting attendance improved abstinence considerably more than did adherence to prescribed medication.
