膝关节骨性关节炎辨证要素积分表的建立及信度分析

The Peliability of KOA Differentiation Faltors Integral Table

目的建立膝关节骨关节炎辨证要素积分表并评价其信度。方法依据《中医临床路径实用指南》《中医诊断学》和《中药新药临床研究指导原则》，结合膝关节骨关节炎的特点，制定KOA中医辨证要素诊断标准。采用克朗巴赫d系数法检验积分表各维度的内部一致性信度。结果各因子克朗巴赫α系数在0．531-0．846之间，但因子苔白而于涩所得总分为0分，4个难度的克朗巴赫，α系数均大于0．7。结论KOA辨证要素积分表的信度较高，部分条目需要进一步的修正和调试。

Objective To preliminarily establish KOA differentiation factors integral table and assess it＇s reliability. Methods Referring to ＂A Practical Guide to The Clinical Pathway of Chinese Medicine＂, ＂Diagnoslics of Chinese Medicine ＂, ＂Clinical Research Guiding Principle of TCM New Drug＂ and the characteristics of KOA, we formulated the TCM diagnostic criteria and differentiation factors integral tbale of KOA. Using the Cronbach＇s coefficient to test the internal consistency reliability of each dimension in the table. Results Cronbach＇s alpha coefficients were Between 0.531 to 0.846,the score of ＂white and dry fur＂was 0.813-0.846. Cronbach＇s alpha coefficients of 4 syndrome dimensions were greater than 0.700. Conclusion KOA differentiation factors integral table has good validity. Some items need to be further modified and debugged.
