《抑郁症中医证候要素辨证量表》的信度和效度研究

目的评价《抑郁症中医证候要素辨证量表》的信度和效度。方法收集232例抑郁症患者,采用测量重测信度、分半信度和内部一致性信度来评价信度,利用标准关联效度、结构效度评价效度。结果各证候要素的重测相关系数在0.612~0.977之间,总量表的Cronbach’sα系数为0.892,分半信度为0.849,Kappa系数在0.689~0.892之间,因子分析结果 8个公因子与预想的结果大体一致,累积贡献率为53.43%。结论《抑郁症中医证候要素辨证量表》具有较好的信度和效度。

Reliability and validity of Scale for TCM Pattern Element Differentiation of Depression

Objective To review the reliability and validity of the Scale for TCM Pattern Element Differentiation of Depression.Methods The reliability was detected by using test-retest reliability,splithalf reliability and internal consistency reliability,and validity was evaluated by using criterion related validity and construct validity in 232 patients with depression.Results The correlation coefficient of test-retest reliability of each pattern element was between 0.612 and 0.977,Cronbach's α coefficient of the total scale was 0.892,split-half reliability was 0.849,and Kappa coefficient was between 0.689 and 0.892.The results of factor analysis showed that 8 common factors were roughly consistent with anticipated results,and accumulating contribution rate was 53.43％.Conclusion The Scale for TCM Pattern Element Differentiation of Depression has higher reliability and validity.
