Abstract

Background. To evaluate development and progression of functional limitation and retain comparability with established approaches, we raised the measurement ceiling of commonly used self-report and performance-based measuresof function. This study evaluated the utility and concurrent validity of these expanded measures. Methods. The study population consisted of 3075 black and white men and women aged 70 to 79 years, with no reported mobility limitations or disability, participating in the Health, Aging, and Body Composition, or Health ABC study. Self-report measures were expanded by ascertaining case of performance and including more demanding levels of some tasks. A single foot stand and narrow walk supplemented an established performance battery. For walkingendurance, we developed the Long Distance Corridor Walk (LDCW), which includes distance covered in 2 minutes and the time to walk 400 m. Results. The expanded self-report items identified one half of the men andone third of the women as exceptionally well functioning and 10% to 13% ofmen and 21% to 36% of women with lower capacity. The supplemented and re-scored performance battery discriminated function over the full range. The LDCW further differentiated walking capacity at the high end and also identified a subgroup with limitations. The self-report and performance measures were significantly, but weakly, correlated (0.13-0.35) and were independentpredictors of walking endurance. Conclusions. Well-functioning persons in their 70s exhibit a broad range of functional capacity readily ascertained by expanded self-report and performance tests, Significant associations among these measures support their concurrent validity, but generally weak correlations indicate they tap different, but important, dimensions of physical function.
