| Annotation | The impact of age and cognitive function on the reproducibility of a performance-based and self-reported measure of functional status was investigated. The Zutphen Elderly Study is a longitudinal investigation of men born between 1900 and 1920 living in Zutphen, the Netherlands. Of a random sample of 114 men from the 1995 survey, 105 (mean age 79.9) participated in a test-retest study, comprising a questionnaire on disabilities, and 4 performance tests twice, in a 2-week interval: standing balance, walking speed, chair stand, and external shoulder rotation. The number of self-reported disabilities in basic activities of daily living (ADL), mobility, and instrumental activities of daily living (IADL) were assessed. Kappa statistics and Pearson correlation coefficients between test and retest measurements were computed for the total group and stratified by age and cognitive function. In the group of subjects tested, performance tests and self-reported disabilities had moderate to good reproducibility, with the exception of poor reproducibility for the test for standing balance. In very old or cognitively impaired populations, self-reported functional status may have lower reproducibility. (RH). |
