To identify major problems that obscure understanding of quality of life; to differentiate quality of life from other closely related concepts, and to offer a definition of quality of life. Quality of life is a term frequently used, but seldom defined, in nursing research. Multiple interpretations and measures make evaluating research difficult. The need to clarify concepts, develop nursing theory, and enhance communication is significant. Concept clarification is also essential for research instrument development and evaluation. ORGANIZING CONSTRUCT AND SCOPE: Concept analysis as proposed by Walker and Avant. Preconceived theories were avoided to keep the analysis as unbiased as possible. The analyst considered many descriptions of quality of life, but eventually included only those in the scientific literature. ⋯ A model showing the relationships among quality of life, well-being, functional status, and satisfaction with life is provided and a definition of quality of life is offered. Researchers and authors should include the definition of quality of life used in their work. Instruments should reflect the theoretic definition used. Care should be taken to clarify if functional status, well-being, satisfaction with life are the concepts under consideration as reflecting a part of overall quality of life.
