This bibliography brings together much of the literature prepared by individuals, organizations, and agencies that have designed or are attempting to design instruments for the definition and measurement of the levels of health within a given population. It includes citations and abstracts of documents identified by the National Health Planning Information Center between May and October 1976 from literature searches of the files of the center, the Clearinghouse on Health Indexes, the National Technical Information Service, Medline, and other automated and manual sources of information. This bibliography does not represent an exhaustive literature search; it was designed to be used as a reference aid to a selection of documents relevant to the methodologies of community health assessment. All references to documents have been classified according to three major subject categories: Health Status Measures, Health Status Assessment Studies, and the Evaluation of Health Care Services. All citations are accompanied by an abstract of the material contained in the document. An author index is included. (MM)
