The authors describe the use of community development theory to assess the need for a community-based, nurse-managed primary care clinic. A community development model provided the framework for citizen participation in identifying collective health needs of public housing residents. The model facilitated the following: 1) planning for delivery of culturally appropriate primary care services that respond to health needs perceived by community residents; 2) ensuring acceptability and use of services; and 3) empowering residents to take responsibility for their own health. This article focuses on the assessment phase of the model and meeting the perceived needs of community residents.
