健康儿童中医体质辨识表的检验研究

Analysis on Test of Identification Scale of Healthy Children's TCM Constitutions

目的：评价＂1~6岁健康儿童中医体质辨识表＂的信度和效度。方法：信度检验方法为调查者对儿童家长进行询问,填写辨识表,评价内部条目的一致性。重测信度检验方法为抽取50名儿童,对儿童家长进行调查,间隔1 d,由另一名调查者再次询问并填写辨识表,检验条目的稳定性。经验效度检验方法为抽取60名儿童进行调查,填写辨识表,再由另一名中医儿科专家根据临床经验得出体质辨识结果,分析两次结果的一致性。结构效度采用主成分分析法对辨识表48个条目进行分析,检测辨识表结果与临床意义相符性。结果：6个亚辨识表Cronbach’sα系数为0.64~0.75,删除某一条目后的α系数与亚辨识总表进行比较,α系数没有明显提高;重测信度检测除阴虚质条目1（手足心偏热）外,各条目再现性系数为0.61~0.82,六个亚辨识表的再现性系数为0.64~0.86;经验效度评价一致率达90%;48个条目分成3个主成分（平衡、偏实和偏虚）,平和质条目构成1个主成分,绝大部分阳盛质条目构成1个主成分,痰湿质条目、气虚质条目、阴虚质条目和阳虚质条目共同构成了1个主成分。结论：＂1~6岁健康儿童中医体质辨识表＂具有较好的信度和效度,为儿童中医体质辨识提供了一种科学和实用的工具。

Objective： To analyze the reliability and validity of identification scale of healthy children＇s TCM constitutions at age 0 to 3 years old.Method： The test method of reliability was to make questions of children＇s parents by investigators,and then we filled the identification table and evaluated the consistency of inner-items. Retest method of reliability was to extract 50 children and investigated the parents,an interval of one day. Another investigator made the same questions and filled the scales again,and then tested the stability of items. The test method of empirical validity was to extract60 children for investigation,filling the scale,and then another TCM pediatrician got the identification results of the constitutions by clinical experience to analyze the consistency of the two results. The principal component analysis was used to analyze the 48 items of identification scales. We tested the conformance of the results of scales and clinical significance.Results： Cronbach＇s α of 6 mild-identification scale was 0.64 ~ 0.75. Compared with the coefficients α deleting one item with mid-identification scale,the coefficients α wasn＇t increasing significiantly. Except 1 item of Yin-deficiency constitution（ the palms of hand and soles of foot was heat partialy）,the reproducibility coefficients of test-retest reliability was 0.61 ~ 0.82. The 48 items were divided into three major cimponents which were balance,relative empirical and relative deficiency and each item of balance consititution and major Yang excess consititution constituted a major component. The items of Yin-deficiency,Yang-deficiency,qi-deficiency and phlegm-dampness constituted one major consititution.Conclusion： The identification scale of healthy children＇s TCM constitutions at age 0 to 3 years old did a good job on the reliability and validity and it is a method to identificate healthy children＇s TCM constitutions.
