The research team matched and mismatched clients to inpatient vs. outpatient alcoholism treatment in a community field setting based on their drinking problem severity and cognitive functioning measures. Treatment consisted of 21 days of primary (inpatient or outpatient) care and 6 months of outpatient aftercare. Participants subsequently were followed for 18 months postprimary care. The results will contribute to the existing knowledge-base on efficient and effective client placement criteria.
