Center faculty member Joseph J. Sudano, Jr., PhD, Assistant Professor of Medicine and Epidemiology and Biostatistics, has been awarded a 3-year grant from the National Institutes on Aging to investigate racial/ethnic measurement bias in the most commonly used health survey tools. Along with co-Investigators Patrick Murray MD, Thomas Love PhD, and Neal Dawson, MD, 1320 whites, blacks, English-speaking and Spanish-speaking Hispanics will take a standard health survey and then asked to perform a series of tests to measure physical functions related to the concepts in the survey. Comparisons between the subjective assessments of health and the objective tests of physical performance will be made to determine if there are differences in these measures across the 4 groups. Results will help in designing future health surveys and more accurately understand differences in health status across racial/ethnic groups. Joining Dr. Sudano in this study are consortium researchers from Northwestern University`s Feinberg School of Medicine, including David W. Baker, MD and Gail Huber, PT.
