自我报告健康（SRH）是最常用的措施之一，用于评估与收入有关的健康不平等的国家之间。先前的一项研究表明，28%的受访者在同一次调查中两次被问及性健康和生殖健康问题时改变了对自己健康状况的评估（第一次是作为自我完成问卷的一部分，然后是在个人访谈中）。这项研究重新审视这个问题，使用另一项调查，其中性健康和生殖健康再次被要求两次的答卷人，但这一次的个人访谈是第一次和自我完成第二。我们发现同样的变化的反应，但占主导地位的方向是远离“极端”的类别“优秀”和“差”，这是相反的方向，以前的研究。因此，我们得出结论，最可能的解释是一种管理模式的影响，使人们不太可能选择极端的类别，在一个自我完成的问卷，但不是一个人的采访。然而，这一效应对不平等的衡量标准的影响相对较小。这是因为很大一部分的流动（即向中间阶层的流动）与收入无关，因此不会系统地影响整个社会经济地位衡量标准的健康累积分布。版权所有（c）2006约翰威利父子有限公司。
Self-reported health (SRH) is one of the most frequently employed measures for assessing income-related health inequalities between counties. A previous study has shown that 28% of respondents changed their assessment of their health status when asked a SRH question on two occasions in the same survey (first as part of self-completed questionnaire and then in a personal interview). This study re-examines this issue using another survey where SRH was again asked twice of respondents, but this time the personal interview was first and self-completion second. We find the same variation in responses, but the predominant direction is away from the 'extreme' categories 'Excellent' and 'Poor' which is the opposite direction to the previous study. We therefore conclude that the most likely explanation is a mode of administration effect that makes people less likely to choose the extreme categories in a self-completion questionnaire, but not a personal interview. However, this effect has a relatively minor impact on measures of inequality. This is due to a large proportion of the movement (i.e. movement to the middle) not being related to income and hence does not systematically impact on the cumulative distribution of health across this measure of socio-economic status.
