AnnotationDisability questions require older people to report difficulties with everyday activities using broad responses. The authors aimed to estimate thresholds on tested performance at which self-reports change from one category to another, across a ranges of sociodemographic subgroups. They also aimed to compare reported and tested performance across two national population studies. Samples were from the third US National Health and Nutrition Examination Study (NHANES III) and the Longitudinal Aging Study Amsterdam (LASA). Measures of gait speed, chair stands and peak expiratory flow rate in both studies yielded the validated index of mobility-related physical limitations (MOBLI). Comparisons between the two studies show that lower reported mobility difficulty or inability prevalence in the Dutch sample is attributable both to reporting a higher level of limitation and to better functioning. There is evidence of differences in thresholds for reporting mobility disability, especially across age and income groups in older Americans. (RH).
