The largest portion of the Medicaid undercount is caused by survey reporting error--that is, Medicaid recipients misreport their enrollment in health insurance coverage surveys. In this study, we sampled known Medicaid enrollees to learn how they respond to health insurance questions and to document correlates of accurate and inaccurate reports. We found that Medicaid enrollees are fairly accurate reporters of insurance status and type of coverage, but some do report being uninsured. Multivariate analyses point to the prominent role of program-related factors in the accuracy of reports. Our findings suggest that the Medicaid undercount should not undermine confidence in survey-based estimates of uninsurance.
医疗补助计划参保人数少计的最大部分是由调查报告误差导致的，也就是说，医疗补助计划受益人在健康保险覆盖情况调查中误报了其参保情况。在本研究中，我们对已知的医疗补助计划参保者进行抽样，以了解他们如何回答健康保险问题，并记录准确和不准确报告的相关因素。我们发现，医疗补助计划参保者对保险状况和保险覆盖类型的报告相当准确，但确实有一些人报告称未参保。多变量分析表明，与计划相关的因素在报告准确性方面发挥着重要作用。我们的研究结果表明，医疗补助计划参保人数少计不应削弱人们对基于调查的未参保估计数的信心。
