Social participation in homogeneous and heterogeneous groups of chronic schizophrenics.

Responsiveness of socially withdrawn, regressed chronic schizophrenics to changes in the characteristics of their social environment was examined. It was hypothesized that withdrawn, regressed, hospitalized patients would participate more effectively in problem-solving groups that were heterogeneous in the activity level and "mental health" of its members than in homogeneous groups. 16 Ss rated as withdrawn and regressed and 16 active, improved Ss solved group problems in a homogeneous and heterogeneous group context. Ratings by independent judges, employing a scale devised for this purpose, indicated that both withdrawn and active chronic schizophrenics participate significantly more effectively in a heterogeneous group problem-solving situation than in a homogeneous setting.
