Abstract

Subjective assessment may be incomparable across countries due to differences in reporting styles. Based on two nationally representative surveys from the US and China, this study used data from three anchoring vignettes to estimate to what extent the US and Chinese older adults aged 50 and above differed in their reporting styles of subjective cognitive impairment. Cross country differences of subjective cognitive impairment were then estimated, both before and after adjusting for reporting heterogeneity. Directly assessed word recall test scores were analyzed to evaluate whether findings based on subjective cognitive impairment was consistent with objective performance. The results revealed a discrepancy between self-reported subjective cognitive impairment and directly assessed memory function among older adults: while Chinese respondents reported lower severity levels of subjective cognitive impairment, the US respondents demonstrated better performance in immediate word recall tests. By accounting for differences in reporting styles using anchoring vignettes data, Chinese older adults showed higher levels of subjective cognitive impairment than the US older adults, which was consistent with results from direct assessment of memory function. Non-negligible differences are present in reporting styles of subjective cognitive impairment. Cross country comparison needs to take into account such reporting heterogeneity.
