这项研究开发了一个衡量阿尔茨海默病和相关痴呆症(ADRD)使用医疗保险索赔。验证类似于美国心理学协会的方法,包括(i)内容效度,(ii)结构效度和(iii)预测效度。我们发现,四个项目-医疗保险索赔记录ADRD 1年前,2年前,3年前,在疗养院总共停留6个月-表现出与单一潜在ADRD结构一致的关联模式,这四个项目中的任何两个项目的存在预测认知功能的直接测量以及ADRD的未来索赔。我们的四个项目与单个量的测量是内在一致的。在预测认知功能的直接测量和未来的ADRD索赔时,任何两个项目的存在都比单个索赔更好。
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 (i) content validity, (ii) construct validity, and (iii) 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.
