摘要
目的:对新编制的中医体质量表的性能进行初步评价。方法:①由北京中医药大学基础医学院牵头,北京中医药大学管理学院等单位参加,分别于2004-10/11和2005-03以北京地区自然人群中15岁以上、获得知情同意的458人为调查对象(包括健康者和患病者)实施调查,并对其中的64人实施了再调查。②应用66个条目(包括平和质、气虚质、阳虚质、阴虚质、痰湿质、湿热质、瘀血质、气郁质、特禀质9个亚量表)构成的中医体质量表进行调查。另外,为了研究效标效度,同时进行了健康状况调查问卷(包括生理、心理两大领域)的调查。③通过条目分析筛选条目,然后对筛选条目后形成的量表进行信度、效度分析。通过量表的回答时间和量表的各个条目的回答率评价其实用性。亚量表内条目的一致性用Cronbach’sα系数进行评价。各个亚量表得分的再现性用再现性相关系数进行评价。结果:①量表的回答时间平均为12min,66个条目回答率都很高(94%~100%)。亚量表内条目间的相关高(0.8以上)的条目有1组,条目与其所属亚量表得分低的(0.3以下)条目有6组,其中属于阳虚质的条目58“喜热饮食”,专家讨论认为应该保留。所以,通过条目分析去除了6个条目。②对完成的由60个条目构成的中医体质量表进行信度、效度评价。本量表9个亚量表得分的再现性相关系数为0.77~0.90,9个亚量表的内部一致性系数为0.72~0.82。与健康状况调查问卷的效标效度的评价结果显示,正常质呈显著正相关(r=0.546,P<0.01),而各个病理体质类型呈显著负相关(r=-0.257~-0.579,P<0.01)。结论:新编制的60个条目构成的中医体质量表实用性、再现性、尺度内一致性的性能评价良好。另外,与健康状况调查问卷比较也呈示了效标效度。因此,可以认为这个量表性能是良好的,可作为中医体质分类的一个工具和尺度。
AIM: To evaluate performance of a newly developed measurement, the Constitution in Chinese Medicine Qnestionnaire(CCMQ).
METHODS: (1) Totally 458 subjects (healthy subjects and illness subjects) above 15 years old on the base of informed consent were selected from Beijing area and surveyed at School of Basic Medical Sciences, Beijing University of Traditional Chinese Medicine and Management College, Beijing University of Traditional Chinesd Medicine in October and November, 2004 and March 2005 respectively. Among them, 64 subjects were surveyed again. (2) CCMQ contained 66 items including nine subscales: gentleness type, qi-deficlency type, yang-deficiency type, yin-deficiency type, phlegm-wetness type, wet-heat type, bloed-stasis type, qidepression type, and special diathesis type. Moreover, the survey of SF-36 including physical and mental summary was used in order to evaluate criterion validity at the same time. (3) Response time to questionnaire and response rate of each item were used to assess practicality. After the item analysis, data were evaluated their reliability and validity. Cronbach's a coefficient was used to assess internal consistency in sub-scale, while interclass correlation coefficient (ICC) was used to assess test-retest reliability using a subpopulation of 64 subjects. Criterion validity was evaluated by correlation coefficient of CCMQ sub-scale to SF-36.
RESULTS: (1) The average time of response was 12 minute, and the response rate of 66 items ranged from 94% to 100%. In sub-scale items, one group was high correlation (〉 0.8). Six groups with low correlation coefficient less than 0.3 between the sub-scale and its items were deleted. However, the item 58 (like hot bite and sup) was should be kept after professional discussion. (2)The evaluation of reliability and validity was further conducted on the remaining 60 items. The test-retest reliability (ICC) for each of the sub-scales score ranged from 0.77 to 0.90 and internal consistency (Croubach's a) for each of the sub-scales was 0.72 to 0.82. Regarding the criterion validity, the correlation coefficients between the nine sub-scales and SF-36 were as follows: Gentleness type was positive correlation (r=0.546, P 〈 0.01), while other pathological constitutional types were negative correlation (r=-0.257 to -0.579, P〈0.01).
CONCLUSION: This study indicates that the CCMQ has good test-retest reliability and internal consistency. The criterion validity of the CCMQ also shows good .In addition, the CCMQ seemed to be valuable in practicality,with short response time, The CCMQean be used as a valuable measure for assessing the constitutional types of traditional Chinese medicine.
