| Annotation | Functional assessments and direct measures of physical performance are standard components of community-based studies of older populations. Estimates of the reliability of these measures are necessary for the assessment of functional change. The reproducibility of 13 measures of self-reported function and 11 direct measures of physical performance was assessed. 199 older people were tested in their homes twice, 48 hours apart, by the same interviewer to replicate study conditions. Results showed that three commonly used measures (chair stand, walking speed and 360 degree turn) may be less reliable than previously reported. Sample sizes that may be needed to detect changes in these areas of performance may be larger than previously estimated given this level of imprecision. Future studies of reproducibility should assess both the level of agreement and the presence of possible practice effects. (AKM). |
