中文摘要
研究目的:
应用EQ-5Q量表以及SF-36量表对KOA患者的生活质量进行评价,通过与SF-36量表的比较分析,探讨 EQ-5D 量表在膝关节骨性关节炎领域的信度和效度。
研究方法:
以北京市老年医院骨性关节炎门诊患者及其合作的社区中已确诊的膝关节骨性关节炎患者为研究对象进行量表调查。成立量表调查小组,对小组进行量表调查的培训。调查过程:对 KOA 患者进行 MMES 量表的填写,进行受试者的筛选;对 KOA患者进行 EQ-5D 量表以及 SF-36 量表的填写,每次调查均采用一对一问答形式,要求调查者每次询问方式保持一致,确保受试者理解量表内容再记录答案,保证实验结果的准确性。EQ-5D 量表先后进行两次填写,两次间隔时间两周;对调查结果进行数据的整理与录入。通过内在等级相关系数评价量表的重测信度、Cronbach's α系数来评定 EQ-5D 量表的内部一致性、用 Pearson 相关系数分析测试者间信度;条目的得分与总分的相关分析检验内容效度,比较分析 EQ-5D 量表及 SF-36 量表的相关性测量效标效度。

(3)效标效度:焦虑与总体健康、精神健康、SF-36 总分、活力、社会功能、情感职能相关系数是-0.365、-0.262、-0.316、-0.451、-0.438、-0.438;VAS 与 SF-36 量表的精神健康相关系数是 0.308,与 SF-36 量表总分的相关系数是 0.354.
研究结论:
(1)EQ-5D 量表具有良好的内部一致性、重测信度以及复本信度。EQ-5D 量表测试结果具有较高的可靠性,在膝关节骨性关节炎领域具有较高的信度。
(2)EQ-5D 量表的内容效度高、结构效度较好,与 SF-36 的效标效度一般。
(3)EQ-5D 量表对评价 KOA 患者生活质量具有较高的信度及可接受的效度。

ABSTRACT
Objective:
Application of EQ-5Q scale and the MOS item short from health survey(SF-36)in patientswith KOA, comparison and analysis the data between EQ-5D and SF-36 scale, studyEQ-5D 's reliability and validity in the field of knee osteoarthritis.
Methods:
In the investigation ,we can see that the knee osteoarthritis patients have beendiagnosed in elderly osteoarthritis patients and BeiJing elderly hospital as the researchobject.The establishment of scale investigation team, for the survey of group training.Theinvestigation process:The patients of KOAwith MMES scale, selection of subjects; thepatients of KOA with EQ-5D scale and SF-36 scale to fill in each survey are used, one toone question and answer form, require investigators ask each time line, to ensure that thesubjects understand the scale content and then record the answer, ensure the accuracy ofthe experimental results.The EQ-5D scale has carried out two times to fill in, the two timeinterval of two weeks; every time the end of the investigation were collected and the dataentry.Through the internal rank correlation coefficient evaluation scale test-retest reliability,Cronbach 's alpha coefficient to evaluate the EQ-5D scale internal consistency, Pearsoncorrelation coefficient analysis test interrater reliability; scores and total scores of entries ofcorrelation analysis test content validity, comparative analyses of correlation measurementschool EQ-5D scale and SF-36 scale standard validity.
Results:
1,The feasibility of scale:The collected a total of 150 subjects, the EQ-5D scale actualrecovery and effective completion of 141 cases, the effective rate of recovery is 94%, theaverage test time is 3 minutes, EQ-5D scale has feasibility.
