A landlord-supervised cooperative apartment program—a new type of community residential treatment modality—was developed through the collaborative effort of a state mental hospital, the Massachusetts Department of Public Welfare, and citizens as landlords. The authors make a number of comparisons between this modality and more conventional facilities such as halfway houses, family care homes, nursing or rest homes, and independent apartments or rooming houses. They conclude that in a community such as the one described this modality appears to be financially and logistically superior to the others.Abstract Teaser
