Description
Yingyan Wu and co-authors fix a score drift in a long study of aging in China. The study appeared in 2024. The study tests memory with word lists across five waves over a decade. From 2018, the words and the way tests were given changed, which broke score links across years.
The team built a fair-match group of over eleven thousand adults, matched by age, sex, and schooling. In that group they lined up score ranks between the old and new waves. Raw scores in later waves looked too high next to 2015. After the fix, wave scores lined up well. The method lets later work track true mind change over time.
