Does reporting heterogeneity bias the measurement of health disparities?
研究使用锚定小短文法识别印尼、印度和中国不同人群在健康报告上的差异，发现纠正报告异质性后，教育导致的健康差距略有缩小（中国除外），收入导致的差距则有所扩大，但整体上报告偏差并不显著。
Heterogeneity in reporting of health by socio-economic and demographic characteristics potentially biases the measurement of health disparities. We use anchoring vignettes to identify socio-demographic differences in the reporting of health in Indonesia, India and China. Homogeneous reporting by socio-demographic group is rejected and correcting for reporting heterogeneity tends to reduce slightly estimated disparities in health by education (not China) and to increase those by income. But the method does not reveal substantial reporting bias in measures of health disparities.
