简短版中医健康量表和欧洲五维健康量表在脑卒中患者中的测量特性评价

Measurement characteristics evaluation of SF-HSTCM and EQ-5D-3L among patients with stroke

目的评估简短版中医健康量表(The Short Form-Health Scale of Traditional Chinese Medicine,SF-HSTCM)和欧洲五维健康量表(The Three-level Euro Qol Five-dimensional Questionnaire,EQ-5D-3L)在脑卒中恢复期患者中的测量特性及其适用性。方法本研究采用横断面调查的方法,以脑卒中恢复期的患者为研究对象,调查的问卷包括SF-HSTCM、EQ-5D-3L、改良Rankin量表(Modified Rankin Scale,mRS)和巴氏量表(Barthel Index,BI)。统计学方法主要包括用Cronbach’sα系数及验证性因子分析分别评估SF-HSTCM的信度及效度,组内相关系数评估SF-HSTCM、EQ-5D-3L、mRS和BI的重测信度及患者与代理人之间一致性信度,而会聚效度用SF-HSTCM与EQ-5D-3L之间的相关程度来进行评价,并采用非参数检验评估SF-HSTCM的区分效度,多重线性回归的方法分析社会人口学因素对于BI、mRS得分的影响。结果共205人完成了调查,SF-HSTCM在脑卒中恢复期患者中的内在一致性Cronbach’sα系数为0.895,重测信度组内相关系数为0.991;EQ-5D-3L的重测信度结果显示两次调查完全一致的问卷数占总数的90%。结论 SF-HSTCM及EQ-5D-3L均可应用于脑卒中恢复期人群的健康状态评测。

Objective To evaluate the measurement characteristics and applicability of The Short Form-Health Scale of Traditional Chinese Medicine(SF-HSTCM) and The Three-level Euro Qol Five-dimensional Questionnaire(EQ-5D-3L) for patients recovering from stroke.Methods The study followed a cross-sectional design.We investigated patients with stroke on the recovery stage.Questionnaires applied in the study included SF-HSTCM,EQ-5D-3L,Modified Rankin Scale(mRS) and Barthel Index(BI).We analyzed the reliability and validity of SF-HSTCM by the Cronbach’s alpha coefficient and confirmatory factor,test-retest reliability of SF-HSTCM,EQ-5D-3L,mRS and BI,and consistency coefficient between patients and agent by interclass correlation coefficient,correlation between SFHSTCM and EQ-5D-3L by convergent validity,discriminant validity of SF-HSTCM by nonparametric test.The impact of Social and demographic factors on score of BI and mRS was evaluated by multiple linear regression.Results A total of 205 people were investigated.The internal consistency of Cronbach’s α among patients with stroke in the recovery phase was 0.895,intercorrelation coefficient of test-Retest reliability was 0.991.The test-retest reliability result of EQ-5D-3L showed that questionnaires of two surveyswhich was exactly the same,accounting for 90% of the total number.Conclusion SF-HSTCM and EQ-5D-3L can be used to evaluate the health status of the patients with stroke in the recovery phase.
