Self-rated health (SRH) is one of the most important social science measures of health. Yet its measurement properties remain poorly understood. Most studies ignore the measurement error in SRH despite the bias resulting from even random measurement error. Our goal is to estimate the measurement reliability of SRH in contemporaneous, retrospective, and proxy indicators. We use the National Longitudinal Study of Adolescent to Adult Health to estimate the reliability of SRH relative to proxy assessments and respondents’ recollections of past health. Even the best indicators – contemporaneous self-reports – have a modest reliability of ~0.6; retrospective and proxy assessments fare much worse, with reliability less than 0.2. Moreover, not correcting for measurement error in SRH leads to a ~20–40% reduction in its correlation with other measures of health. Researchers should be skeptical of analyses that treat these subjective reports as explanatory variables and fail to take account of their substantial measurement error.

青春期的主观健康:比较整体健康的同期、回顾性和代理报告的可靠性

自评健康(SRH)是最重要的健康社会科学衡量标准之一。然而,它的测量特性仍然知之甚少。大多数研究忽略了 SRH 的测量误差,尽管即使是随机测量误差也会产生偏差。我们的目标是估计 SRH 在同期、回顾和代理指标中的测量可靠性。我们使用全国青少年到成人健康纵向研究来估计 SRH 相对于代理评估和受访者对过去健康状况的回忆的可靠性。即使是最好的指标——同时期的自我报告——也有大约 0.6 的适度可靠性;回顾性评估和代理评估的情况要差得多,可靠性低于 0.2。而且,不纠正 SRH 的测量误差会导致其与其他健康指标的相关性降低约 20-40%。研究人员应该对将这些主观报告视为解释变量的分析持怀疑态度,而没有考虑到它们的重大测量误差。
