老年高血压病肾气亏虚证诊断量表的信度与效度测评

Analysis of Reliability and Validity of Deficiency of Kidney "Qi" Identification Scale for Elderly Hypertention

目的分析初建的老年高血压病肾气亏虚证宏观诊断量表的信度和效度。方法用该量表对425例老年高血压病患者进行调查,分别计算信、效度值。结果重测信度、分半信度、同质性信度、内部相关系数、评分者信度系数均在0.6以上;肾气亏虚证组量表各维度得分与非肾气亏虚证组有显著差异;因子分析提取3个公因子,方差累计贡献率为73.136%,旋转因子模型结构与量表维度及条目设置完全吻合。结论老年高血压病肾气亏虚证宏观诊断量表具有良好的效度和信度,可以利用其进行老年高血压病肾气亏虚证的证候诊断研究。

Objective To study the reliability and validity of deficiency of kidney ＂Qi＂ identification scale for elderly hypertention.MethodsThe identification scale was sent to 425 clinical elderly hypertension patients.The reliability and validity of each module and the total scale were tested.ResultsThe test-test reliability coefficient,Split-half reliability coefficient,Chronbach＇s coefficient,Intra-unit Correlation Coefficient,scorer reliability coefficient were all higher than 0.6.Factor analysis showed that each module was abstracted three factors and the total contribution rate was 73.136%.The result after varimax rotation was consistent with the theory.ConclusionThe scale has good reliability and validity and can be used for syndrome studies of kidney ＂Qi＂ identification scale for elderly hypertension.
