气滞证自评量表第三轮专家问卷分析

Analysis of Third Round of Expert Questionnaire Survey on Self-Rating Qi Stagnation Scale

目的调查专家对气滞证的诊断经验,为建立气滞证量化工具筛选条目。方法通过德尔菲法对全国各地12位专家进行第三轮问卷调查,根据每个条目的重要性评分计算均数、满分比和变异系数,再根据三者的界值筛选条目,采用Kendall W值反映专家的协调程度,采用专家权威程度系数反映专家的权威程度。结果第三轮专家咨询回收率为100%。肝维度共24个条目,主要反映病情与情志状况;胆维度共4个条目,主要反映胁肋胀痛状况;胃维度共11个条目,主要反映胃脘部的痞满、胀痛、气逆状况;肠道维度共9个条目,主要反映腹部的胀痛和大便状况;心维度共7个条目,主要反映胸部胀痛和情志状况;肺维度共2个条目,主要反映胸闷、咳嗽、气喘状况;胞宫维度共4个条目,主要反映痛经和小腹部胀痛状况。以上所有条目的均数、满分比均大于界值,变异系数均小于界值。Kendall W值为0.474(χ2值为506.21,P<0.01),权威程度系数为0.84。结论 12位专家的积极程度和专业程度较高,意见可信度较高,且协调程度较高,为编制气滞证自评量表提供了参考依据。

Objective To investigate the experts＇experience in the diagnosis of qi-stagnation syndrome and to screen items for the establishment of quantitative tools for qi-stagnation syndrome.Methods The third round of questionnaire survey was conducted in 12 experts from different regions of China with Delphi method.The mean,full mark ratio,and coefficient of variation were calculated based on the importance of each item.Then the items were screened according to the cut-off values of the three indices,and Kendall W and authority coefficient were used to reflect the concordance and authority of experts,respectively.Results The response rate of the third round of expert questionnaire survey was 100%.There were 24 items on liver dimension,mainly reflecting the state of illness and emotion;4items on gallbladder dimension,mainly reflecting the distending pain in hypochondrium;11items on stomach dimension,mainly reflecting the stuffiness,distending pain,and reversed flow of qi in gastric cavity;9items on intestinal tract dimension,mainly reflecting the distending pain of abdominal area and the condition of stool;7items on heart dimension,mainly reflecting the distending pain of chest and emotion;2items on lung dimension,mainly reflecting chest distress,cough,and asthma;4items on uterus dimension,mainly reflecting dysmenorrhea and the distending pain of lower abdomen.For all items,the mean and full mark ratio were greater than the cut-off values,while the coefficient of variation was less than the cut-off value.The Kendall W was 0.474（χ^2= 506.21,P〈0.01）,and the authority coefficient was 0.84.Conclusion The 12 experts have high degrees of positivity and specialization,as well as high credibility and concordance,which will provide a reference for the establishment of Self-Rating Qi Stagnation Scale.
