目的:评价虚寒证量表的信度和效度,以提高中医量表制定水平。方法:根据中医虚寒证临床辨证症状学的调查资料,通过对1000例受试者的测量,筛选40项条目,编制成中医虚寒证量表。采用奇偶分半法,测量分半信度;计算Cronbach’sα系数测量内部信度;以Kappa和ICC判断评判者信度;通过相关分析及t检验测量判别效度;通过因子分析判别结构效度。结果:量表的Cronbach’sα系数为0.8942,各项的Cronbach’sα系数均大于0.65;分半信度在0.83以上;Kappa值为0.7330;ICC为0.73;因子分析显示量表结构效度好。结论:中医虚寒证量表具有较好的信度和效度。
OBJECTIVE: To evaluate the reliability and validity of Deficiency and Cold Syndrome Scale in order to improve the formulation of TCM scale. Methods: According to the survey data of Syndrome Differentiation and Syndrome Differentiation of Deficiency-Cold Syndrome in Traditional Chinese Medicine (TCM), 40 items were screened by measuring 1000 subjects, and the Deficiency and Cold Syndromes of Traditional Chinese Medicine was compiled. Using the odd and even halves to measure the half-reliability; calculating Cronbach’sα coefficient to measure the internal reliability; using Kappa and ICC to judge the reliability of the judge; using the correlation analysis and t-test to measure the discriminant validity; . Results: The Cronbach’s alpha coefficient of the scale was 0.8942, the Cronbach’s alpha coefficient of each item was greater than 0.65; the half reliability was above 0.83; Kappa was 0.7330; the ICC was 0.73; Factor analysis showed that the scale structure validity was good. Conclusion: The Deficiency and Cold Syndrome Scale of TCM has good reliability and validity.
