目的:评价"亚健康状态中医证候调查问卷"的信度和效度。方法:3个中心采集亚健康人群有效样本268例,健康人群有效样本86例,并对其中65例亚健康人群实施了再调查,63例亚健康人群进行了效度检测。结果:①信度检测方面,问卷总体及各维度的克朗巴赫α系数值、折半系数值和稳定系数值分别在0.70-0.95,0.67-0.87,0.88-0.98之间;②效度检测方面,校标效度表现不佳;区分效度表现为亚健康人群、健康人群在问卷各维度及总体得分均具有明显的统计学意义(P〈0.01);结构效度采用因子分析,按特征根值〉1提取出12个公因子,累积贡献率为63.632%。结论:该问卷具有较好的信度和效度,可以作为亚健康状态中医证候分类的一个工具和尺度。
Objective: To evaluate the reliability and validity of TCM syndrome questionnaire of sub-health state.Methods: Through the investigation,we collected 268 valid cases of sub-health population and 86 valid cases of health population from 3 centers,and we retested 65 cases of sub-health population,tested the validity of 63 cases of sub-health population.Results: ① On the reliability,in terms of the the overall and the dimensions of the questionnaire,the Cronbach α coefficient,split-half coefficient and stability coefficient range from 0.70 to 0.95,0.67 to 0.87,0.88 to 0.98 respectively;② On the validity,in addition to poor criterion validity,there are clear statistical significance(P0.01)in the dimensions and overall scores between the people of sub-health and healthy in the questionnaire;through factor analysis,there are 12 factors that the eigenvalue is above 1,the cumulative contribution rate is 63.632%.Conclusions: The questionnaire has a good reliability and validity,which can become a tool and scale to classify the syndromes of sub-health state.
