This study examined the effects of social competence, social support, and their interaction in predicting the community integration and well-being of young chronically disabled, mentally ill adults.

Significant positive relationships were found between social competence and community integration, emotional support and well-being, and community integration and well-being. The interaction of emotional support and community integration was significant in its prediction of well-being. The interaction of social competence and community integration was significant in predicting well-being when emotional support was held constant. Implications for housing, research, and policy for community care are discussed.Community integration and well-being of chronically disabled, mentally impaired adults were goals of deinstitutionalization and community-based care.

Housing is one of those basic resources, and the lack of available housing is most obvious in the increasing number of homeless people, among whom are many chronically disabled, mentally impaired individuals. The lack of housing continues to obstruct the full realization of community-based care, and as a result
