目标。消费者调查被越来越多地用于评估健康计划、医生团体和临床医生提供的医疗服务的质量。消费者健康计划评估研究（CAHPS(TM)）的目的是制定一套综合和标准化的调查，旨在从消费者那里收集有关健康计划执行情况的可靠和有效信息。本文报告了CAHPS(TM) 1.0调查项目在医疗补助或私人健康保险覆盖的个人样本中的心理测量结果。方法：在5878名医疗补助人员和11393名私人医疗保险人员的样本中估计camp (TM) 1.0措施的可靠性估计。CAHPS（TM）健康计划的全球评级与推荐计划的意愿和重新注册的意图的相关性在313名医疗补助人员的样本中进行了估计。在后一个样本和539名拥有私人健康保险的人的样本中，还调查了健康计划的评级与使用5分优秀到差反应量表的评级之间的关系。CAHPS（TM）测量似乎具有良好的可靠性，特别是在健康计划水平上。每个健康计划的300名消费者的回答往往会产生足够可靠的估计，用于健康计划的比较，特别是在私人保险中。全球健康计划评级与消费者向家人和朋友推荐计划的意愿以及如果有选择的话他们重新参加计划的意愿显著相关。CAHPS(TM) 1.0量表具有优异的心理测量性能。
OBJECTIVES. Consumer surveys are being used increasingly to assess the qualify of care provided by health plans, physician groups, and clinicians. The purpose of the Consumer Assessment of Health Plans Study (CAHPS(TM)) is to develop an integrated and standardized set of surveys designed to collect reliable and valid information about health plan performance from consumers. This article reports psychometric results for the CAHPS(TM) 1.0 survey items in samples of individuals with Medicaid or private health insurance coverage.METHODS, Reliability estimates for CAMPS(TM) 1.0 measures were estimated in a sample of 5,878 persons on Medicaid and 11,393 persons with private health insurance. Correlations of the CAHPS(TM) global rating of the health plan with willingness to recommend the plan and intention to re-enroll were estimated in a sample of 313 persons on Medicaid. The association of the rating of the health plan with ratings using a 5-point Excellent-to-Poor response scale also was investigated in the latter sample and in a sample of 539 persons with private health insurance.RESULTS. The CAHPS(TM) measures appeared to have good reliability, particularly at the health-plan level. Responses from 300 consumers per health plan tend to yield estimates that are reliable enough for health plan comparisons, especially among the privately insured. The global health plan rating was significantly correlated with consumers' willingness to recommend the plan to family and friends and to their intention to re-enroll in the plan if given a choice.CONCLUSIONS. The CAHPS(TM) 1.0 survey instrument appears to have excellent psychometric properties.
