What Do Self-Reported, Objective, Measures of Health Measure?
利用匹配自我报告与医疗记录的数据，检验了慢性病自我报告作为客观健康指标的可靠性，发现其存在较大回答误差，用作解释变量时会导致严重衰减偏误。
Survey reports of the incidence of chronic conditions are considered by many researchers to be more objective, and thus preferable, measures of unobserved health status than self-assessed measures of global well being. In this paper we evaluate this hypothesis by attempting to validate these “objective, self-reported” measures of health. Our analysis makes use of a unique data set that matches a variety of self-reports of health with respondents’ medical records. We find that these measures are subject to considerable response error resulting in large attenuation biases when they are used as explanatory variables.
