The role of residential homelikeness in promoting community participation by adults with mental retardation.

We tested the influence of (1) the homelike appearance of residences, (2) residential staff-members' attitudes about people with mental retardation and (3) Client IQ on the number of activities adults clients with mental retardation conducted in their community. We tested the hypothesis these three variables exerted their influence by promoting positive staff-member interactions with clients. This was assessed by measuring the duration of Staff-initiated Social Interactions with residential clients. In our initial path model, Residential Homelikeness, Positive Staff Attitudes and Client IQ had no significant direct effect on Community Activities. In the final model, however, Residential Homelikeness and Positive Staff Attitudes exerted a statistically significant influence on Staff-initiated Social Interactions with clients, which in turn, exerted a statistically significant influence on Community Activities. This model illustrated: (1) the nearly equal influence of Staff Attitudes and architectural characteristics on Staff-initiated Interactions; and (2) the role of Staff-initiated Interactions in mediating the influence of Residential Homelikeness on community participation by adults with developmental disabilities.
