评估2003-2004年医疗支出小组调查（MEPS）中医疗结果研究简表2版（SF-12v2）的信度和效度。数据通过邮寄问卷和面对面访谈的方式收集（n = 20,661）。内部一致性、重测信度、建构效度、区分效度、预测效度和并发效度进行了测试。采用EQ-5D、感知健康和心理健康问卷检验构念效度和区别效度。自我报告的工作、身体和认知限制测试了预测效度，慢性病数量评估了并发效度。心理成分总结得分（MCS）和身体成分总结得分（PCS）均具有较高的内部一致性信度（alpha >.80）。PCS具有较高的重测信度（ICC = .78），而MCS具有中等信度（ICC = .60）。PCS对EQ-5D项目（自我保健除外）和身体健康状况具有较高的收敛效度（r = 0.56）。MCS在EQ-5D和心理健康项目上表现出中等收敛效度（r = 0.38）。PCS区分具有不同物理和工作限制的组。同样，MCS可以区分有和没有认知限制的群体。MCS和PCS表现出完美的剂量反应，当参与者的慢性疾病状态检查分数的变化。在2003-2004年的MEPS中，这两个成分的得分都显示出足够的信度和效度，应该适合在这个数据库中的各种建议中使用。
Evaluate the reliability and validity of the Medical Outcomes Study Short-Form version 2 (SF-12v2) in the 2003-2004 Medical Expenditure Panel Survey (MEPS).Data were collected in the self-administered mail-out questionnaire and face-to-face interviews of the MEPS (n = 20,661). Internal consistency and test-retest reliability and construct, discriminate, predictive and concurrent validity were tested. The EQ-5D, perceived health and mental health questions were used to test construct and discriminate validity. Self-reported work, physical and cognitive limits tested predictive validity and number of chronic conditions assessed concurrent validity.Both Mental Component Summary Scores (MCS) and Physical Component Summary Scores (PCS) were shown to have high internal consistency reliability (alpha > .80). PCS showed high test-retest reliability (ICC = .78) while MCS demonstrated moderate reliability (ICC = .60). PCS had high convergent validity for EQ-5D items (except self-care) and physical health status (r > .56). MCS demonstrated moderate convergent validity on EQ-5D and mental health items (r > .38). PCS distinguish between groups with different physical and work limitations. Similarly, MCS distinguished between groups with and without cognitive limitations. The MCS and PCS showed perfect dose response when variations in scores were examined by participant's chronic condition status.Both component scores showed adequate reliability and validity with the 2003-2004 MEPS and should be suitable for use in a variety of proposes within this database.
