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. The 159 participants, all between the ages of 18 and 45, were residents of New York City's supervised and supportive community residences, and single room occupancy hotels with mental health services. 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.
