This article discusses the conceptual and methodological issues that continue to plague health-related quality of life (HRQOL) research. The current conceptualizations of the construct are reviewed to make explicit the issues of diversity and lack of consensus in definitions, validity of the conceptual unity of multiple domains, and lack of attention to the integration of the HRQOL construct into a theoretical meaningful model. Inadequately addressed conceptual issues have resulted in the proliferation of scales to measure HRQOL the measurement issues to a need to focus on precision and sensitivity of measures. The author offers a new conceptualization of HRQOL, which encompasses both health-care provider and patient perspectives.
