摘　　要：目的评价“小儿厌食（喂养障碍）中医证候疗效评价量表”的质量。方法应用“小儿厌食（喂养障碍）中医证候疗效评价量表”的临床调查表采集253例厌食患儿及27例健康儿童，用主成分分析法进行探索性因子分析，用于评价其结构效度；计算量表总分与各维度、条目与各自维度的相关系数，用于评价其内容效度；计算两次测量的量表总分及各维度的相关系数，用于评价其重测信度；计算奇偶条目的Cronbach’s α系数及两者的相关系数，用于评价其分半信度；计算量表总分及各维度的Cronbach’s α系数，用于评价其内部一致性；计算健康儿童与厌食患儿治疗前后中医证候总积分和各维度积分，用于评价其反应度。结果所提取的10个公因子所包含的条目存在试验前所预想的逻辑关系；除阴虚维度外，其他维度与量表总分相关系数均〉0．4（0．42～0．63），除形体偏瘦外，其余条目与本维度的相关系数均〉0．4（0．50～0．83）；两次测量的量表总分相关系数为0．66，各维度相关系数均〉0．4（0．43～1．00）；奇、偶数条目的Cronbach’s α系数分别为0．58、0．55，两者的相关系数为0．64；总量表的Cronbach’s α系数为0．74，各维度的Cronbach’s α系数均〉0．4（0．47—0．72）；健康儿童与厌食患儿各个维度中医证候积分及总分比较、厌食患儿中医证候总积分和各维度积分的治疗前后比较，差异均有统计学意义（P〈0．01）。结论“小儿厌食（喂养障碍）中医证候评价量表”具有良好的信度、效度及反应度，可用于本病各种常见中医证候疗效评价。Objective To evaluate the quality of Clinical Efficacy Scale of Traditional Chinese Medicine （TCM） Syndromes of Infantile Anorexia （Feeding Disorder）. Methods Collect 253 cases of anorectie children and 27 cases of healthy children adopting clinical questionnaire of Clinical Efficacy Scale of TCM Syndromes of Infantile Anorexia （Feeding Disorder）. Use principal component analysis to carry out exploratory factor analysis, which was to evaluate the construct validity. Calculate correlation coefficients between total scores of the scale and dimensions and between dimensions and items to evaluate the content validity. Calculate correlation coefficients twice of total scores of the scale and dimensions to evaluate the test-retest reliability. Calculate Cronbach＇s α of parity items and correlation coefficient of two Cronbach＇s α to evaluate the split-half reliability. Calculate Cronbaeh＇s α of total scores of the scale and dimensions to evaluate the internal consistency. Calculate TCM syndromes total scores of healthy and anorectic children before and after treatment and scores of dimensions to evaluate the responsiveness. Results Items included in 10 extracted common factors possessed logical relation which was preconceived before the test. Besides Yin deficiency dimension, correlation coefficients of total scores of the scale and other dimensions were greater than 0.4 （0. 42 to 0.63 ）. Besides partial lean shape, correlation coefficients of other items and this dimension were greater than 0. 4 （0. 50 to 0. 83 ）. Correlation coefficient of twice calculated total scores of the scale was 0. 66. Correlation coefficients of all dimensions were greater than 0. 4 （0. 43 to 1.00）. Cronbach＇s α of parity items were respectively 0. 58 and 0.55; correlation coefficient of two Cronbach＇s α was 0. 64. Cronbach＇s ot of the scale was 0. 74. Cronbach＇s α of all dimensions were greater than 0. 4 （0. 47 to 0. 72） . The difference of TCM syndromes scores of dimensions and total scores of
