The costs, nature, and benefits of residential supports were examined for 86 adults with mental retardation living in village communities, 133 adults living in newly built residential campuses, and 281 adults living in dispersed housing schemes (small community-based group homes and supported living). Results indicated that (a) the adjusted comprehensive costs of provision in dispersed housing schemes were 15% higher than in residential campuses and 20% higher than in village communities; (b) dispersed housing schemes and village communities offered a significantly greater quality of care than did residential campuses; and (c) there appeared to be distinct patterns of quality of life benefits associated with dispersed housing schemes and village communities, with both approaches offering a greater quality of life than did residential campuses.
