This cross-sectional study explores the reliability and validity of a newly developed 15-item Medicare proficiency questionnaire (MPQ) across a mixed group of participants enrolled and unenrolled in Medicare. The MPQ was designed to assess beneficiary knowledge across a variety of Medicare topics and was developed by combining questions selected from the 2003 Medicare Current Beneficiary Survey and updating it with researcher-generated Medicare Part D questions. During the month of February in 2024, participants enrolled and unenrolled in Medicare, which were recruited on Prolific, completed online surveys which included the MPQ and demographic questions. We found that the MPQ has adequate internal consistency reliability with Cronbach's alpha = .73 across participants enrolled and unenrolled in Medicare as well as adequate validity, as demonstrated by positive relationships of MPQ scores to education level and to enrollment status (enrollees scoring higher).
这项横断面研究探讨了新开发的15项医疗保险熟练度问卷（MPQ）在参加和未参加医疗保险的混合参与者群体中的信度和效度。MPQ旨在评估受益人在各种医疗保险主题方面的知识，它是通过合并从2003年医疗保险当前受益人调查中选取的问题，并结合研究人员提出的医疗保险D部分问题进行更新而开发的。在2024年2月期间，在Prolific上招募的参加和未参加医疗保险的参与者完成了在线调查，其中包括MPQ和人口统计学问题。我们发现，MPQ在参加和未参加医疗保险的参与者中具有足够的内部一致性信度，Cronbach's alpha系数为0.73，并且具有足够的效度，MPQ分数与教育水平和参保状态呈正相关（参保者得分更高）。
