Deinstitutionalization of Persons with Mental Retardation: Behavioral Outcomes

Abstract

This article examines experimental/contrast group and longitudinal studies of the changes in adaptive behavior associated with moving from state institutions to small (15 or fewer people) community living arrangements for persons with mental retardation. It reviews 15 research reports, including 18 separate studies with 1358 subjects that met specific criterion for design and recency. It summarizes outcomes in the areas of overall adaptive behavior, seven specific domains of adaptive behavior, and overall problem behavior. All eight of the experimental/contrast group studies, and 5 of the 10 longitudinal studies reported statistically significant improvement in either overall adaptive behavior or in the basic self-help/domestic domain associated with movement to the community. All 18 studies reported at least some improvement for groups moving from institutions to community living arrangements.
