To examine longitudinal responses to the disability indicator questions that have been adopted as the standard across national surveys sponsored by the US Department of Health and Human Services.
Data from the Current Population Survey between 2008 and 2015 were linked to create a longitudinal sample of 721 178 individual respondents.
Responses to the disability questions fluctuated significantly. Although 17% of all respondents reported a disability at some point, only 3% consistently reported the same set of disabilities. Demographic differences were found between people who always reported a consistent set of disabilities and those whose responses fluctuated.
The disability questions capture 2 discrete groups: people who experience a permanent disability and those who experience a temporary disability. Demographic differences between these groups suggest that this is not simply due to measurement error.
研究对残疾指标问题的纵向反应，这些问题已被美国卫生与公众服务部发起的全国性调查采用为标准。
将2008年至2015年期间当前人口调查的数据相链接，以创建一个由721178名个体受访者组成的纵向样本。
对残疾问题的回答波动很大。尽管17%的受访者在某个时候报告有残疾，但只有3%的人始终报告相同的一组残疾。始终报告一致残疾情况的人与回答波动的人之间存在人口统计学差异。
残疾问题涵盖两个不同的群体：经历永久性残疾的人和经历临时性残疾的人。这些群体之间的人口统计学差异表明，这不仅仅是由于测量误差。
