This paper reports on the findings of an evaluation of a health and social services comprehensive care model project for the elderly residing in low-income urban public housing. The text contains a brief discussion of the previous research, the results of the present study, and comments on the applicability of previous research to the sample within public housing. Findings for the treatment and control groups are discussed separately and a comparison of the two groups is provided for each of six variables of psychological well-being, i.e., (1) socioeconomic status; (2) social participation; (3) perceived health; (4) marital status; (5) age; and (6) sex. The Conclusions section addresses the variables relevant to public housing and overall treatment effects of the model project. Appendix A describes the model project evaluation which examined the project's impact across a random sample (N=98) of residents of treatment and control buildings. Appendix B briefly describes the project, while Appendix C describes the Philadelphia Geriatric Center Morale Scale and Rosenburg's Self-Esteem Scale used as outcome measures. Appendix D contains data tables which help to clarify the research methods. (NRB)
