This project is a national, random digit-dialed telephone survey of 2,800 community-living U.S. adults between the ages of 35 and 89 to collect information on health-related quality of life using four measurement tools that are commonly used around the world: the SF-36, the EuroQol EQ-5D, the Quality of Well-being Scale (QWB-SA), and the Health Utilities Index (HUI). Persons over the age of 65 and African-Americans are being over-sampled to provide a better understanding of how these tools work for these important sub-groups. Information on chronic health problems, psychological well-being, and socio-economic characteristics are also being collected to study how these factors affect health-related quality of life as assessed by these tools.
The key goals of this study are: (1) to develop national "benchmarks" for average scores for each of these health measurement tools, across age, gender, racial, and socio-economic groups; (2) to explore how the results of individual health assessments may vary or be the same if we use different measurement tools; and (3) to better understand how health assessments relate to the presence of chronic conditions, psychological well-being, and socio-economic status. At the end of the study, a public use data set will be available on the internet for other health services researchers who are interested in exploring these issues.
