The use of key informant networks in assessment of community health

Program planning requires the acquisition of current, reliable information to accurately define the need for the program and to aid in developing its basic structure. In a time of financial restraint, a cost- and time-efficient method for collecting information for program development is important. This paper presents a strategy, borrowed from anthropology, that develops a network of key individuals in the community as a source of information and as a potential resource in program development. The effectiveness of this approach as a method for data collection is illustrated through application to a health and medical needs assessment of a geriatric population. A community diagnosis of this population was obtained.
