[Application of health vignettes in correcting self-reported health condition]

To introduce the application of vignettes in the survey on health condition, we took the Hangzhou health survey as an example. We tried to find the respondents' health judgment standard by using vignettes first and discovered the population's demographic characteristics as sex, age, years of schooling and income etc. could influence the self-reported health condition on the response category cut-points. Then the cut-points were corrected through hierarchical ordered probit model in order to reflect the respondents' self-reported health condition based on the same standard, making the result suitable for comparison. Data from our research discovered that the level of health condition of females was lower than that of males among the residents living in Hangzhou and the higher income they received, the better health condition they had. Thus, the health vignettes seemed very essential in the survey on health condition.
