Reliable measures of Medicare beneficiaries' program knowledge are necessary for credible program monitoring, evaluation, and public accountability. This study developed and evaluated the psychometric properties of two possible measures of beneficiary knowledge. One measure was based on self-reported knowledge, the other was a true/false quiz which requires beneficiaries to demonstrate their knowledge. We used data from the 1998 and 1999 Medicare Current Beneficiary Survey (MCBS) to evaluate the reliability and construct validity of the indices. Overall, based on both content considerations and the psychometric analyses, the true/false quiz proved to be the more accurate and useful measure of beneficiaries' knowledge.
对于可靠的项目监测、评估和公共问责而言，衡量医疗保险受益人的项目知识的可靠方法是必要的。本研究开发并评估了两种衡量受益人知识的可能方法的心理测量特性。一种方法基于自我报告的知识，另一种是真假测验，要求受益人展示他们的知识。我们使用了1998年和1999年医疗保险当前受益人调查（MCBS）的数据来评估这些指标的可靠性和结构效度。总体而言，基于内容考量和心理测量分析，真假测验被证明是衡量受益人知识的更准确、更有用的方法。
