This study develops a measure of Alzheimer's disease and related dementias (ADRD) using Medicare claims.
Validation resembles the approach of the American Psychological Association, including (1) content validity, (2) construct validity, and (3) predictive validity.
We found that four items-a Medicare claim recording ADRD 1 year ago, 2 years ago, 3 years ago, and a total stay of 6 months in a nursing home-exhibit a pattern of association consistent with a single underlying ADRD construct, and presence of any two of these four items predict a direct measure of cognitive function and also future claims for ADRD.
Our four items are internally consistent with the measurement of a single quantity. The presence of any two items do a better job than a single claim when predicting both a direct measure of cognitive function and future ADRD claims.
本研究利用医疗保险理赔数据开发了一种阿尔茨海默病及相关痴呆症(ADRD)的测量方法。
验证过程类似于美国心理学会的方法,包括(1)内容效度、(2)结构效度和(3)预测效度。
我们发现四个项目——一份记录一年前、两年前、三年前ADRD的医疗保险理赔单,以及在疗养院总共住了6个月——呈现出与单一潜在ADRD结构一致的关联模式,这四个项目中任意两个项目的存在可预测认知功能的直接测量结果以及未来ADRD的理赔情况。
我们的四个项目在测量单一数量方面具有内部一致性。在预测认知功能的直接测量结果和未来ADRD理赔情况时,任意两个项目的存在比单一理赔单表现更好。
