Self-reported and performance-based instruments are both necessary for a comprehensive view of the functioning of institutionalized older adults. Our aim was to assess the reliability and measurement error of the 12-item World Health Organization Disability assessment Schedule and compare these indexes against performance-based tests.
One hundred participants from Nursing Homes and Day Care Centers were assessed twice (two days to one week apart) by two independent assessors. Reliability and measurement error indexes were calculated.
Reliability of the World Health Organization Disability assessment Schedule total score, and of three performance tests was appropriate for individual comparisons (ICC ≥ 0.92). Reliability for the five times seat to stand test was appropriate for group comparisons only (ICC = 0.84). The high measurement error of the timed up and go test (SEM = 4.25; MDC = 11.78) and of the five times seat to stand test (SEM = 3.47; MDC = 9.62) and the number of participants unable to perform them (TUG: n = 11; FTSST: n = 41) suggest that these tests are less suitable to monitor individual changes.
The 12-item World Health Organization Disability Assessment Schedule total score, the gait speed and hand grip tests could be used to monitor changes at both the individual and group level in a population with decreased functioning. Implications for Rehabilitation The 12-item World Health Organization Disability assessment Schedule, could be used to monitor changes in perceived functioning both at the individual and group level in institutionalized ambulatory older adults. The gait speed and hand grip tests could be used to monitor changes in performance both at the individual and group level in institutionalized ambulatory older adults' functioning. The utility of the time up and go and of the five times seat to stand test might be of limited value when aiming to monitor changes in institutionalized older adults' functioning.
自我报告工具和基于表现的工具对于全面了解机构养老老年人的功能状况均必不可少。我们的目的是评估12项世界卫生组织残疾评定量表的信度和测量误差，并将这些指标与基于表现的测试进行比较。
来自养老院和日托中心的100名参与者由两名独立评估者进行两次评估（间隔两天至一周）。计算信度和测量误差指标。
世界卫生组织残疾评定量表总分以及三项基于表现的测试的信度适用于个体比较（组内相关系数≥0.92）。五次坐立试验的信度仅适用于组间比较（组内相关系数=0.84）。计时起立行走测试（测量标准误=4.25；最小可检测变化=11.78）和五次坐立试验（测量标准误=3.47；最小可检测变化=9.62）的高测量误差以及无法完成这些测试的参与者数量（计时起立行走测试：n=11；五次坐立试验：n=41）表明，这些测试不太适合监测个体变化。
12项世界卫生组织残疾评定量表总分、步速测试和握力测试可用于监测功能下降人群的个体和群体水平变化。康复意义12项世界卫生组织残疾评定量表可用于监测机构养老能走动老年人个体和群体水平上感知功能的变化。步速测试和握力测试可用于监测机构养老能走动老年人个体和群体水平上表现的变化。当旨在监测机构养老老年人功能变化时，计时起立行走测试和五次坐立试验的效用可能有限。
