目的编制一份测量肠脑健康状况的问卷并检验其信效度。方法经查阅文献和访谈形成含31项的预测问卷;分别对180名和479名被试进行项目分析和探索性因素分析以及信效度检验,选状态-特质焦虑问卷、自评抑郁量表和阿森斯失眠量表为效标。结果项目分析和探索性因素分析表明包含3个维度:肠道状态、饮食习惯和排便情况,21个项目的肠脑健康状况问卷,共解释了54.7%的变异;信度分析显示各维度信度系数在0.64~0.79之间,重测信度在0.70~0.78之间;效度分析表明各维度能反映总问卷所要测查的内容;各维度与总分间存在显著相关(r=0.488~0.798,P<0.01);验证性因素结果显示3因素模型各项拟合指数较好(χ2/df=1.728,RMSEA=0.067,CFI=0.869);肠脑健康状况总分与各效标显著负相关(P<0.01)。结论初步编制的肠脑健康状况问卷具有良好的信效度,可用于肠脑健康状况的相关研究。
Objective To prepare a questionnaire to measure the state of intestine brain health and test its reliability and validity. Methods A total of 31 predictive questionnaires were obtained through literature review and interviews. 180 and 479 subjects were analyzed by project and exploratory factor analysis, reliability and validity test, selection status-trait anxiety questionnaire, self-assessment depressive scale and Assen Sri Lanka insomnia scale as the standard. Results Project analysis and exploratory factor analysis showed that there were three dimensions: intestinal status, eating habits and defecation, 21 items of bowel health questionnaire, explaining 54.7% of the total variance; reliability analysis showed that the reliability of each dimension The coefficients of reliability were between 0.64 and 0.79, and the retest reliability was between 0.70 and 0.78. Validity analysis showed that each dimension could reflect the content of the questionnaire. There was a significant correlation between each dimension and the total score (r = 0.488-0.798 (Χ2 / df = 1.728, RMSEA = 0.067, CFI = 0.869). The total score of intestinal health status was significantly negatively correlated with each standard value (P <0.01). The confirmatory factor results showed that the fitting index of three factors model was better (P <0.01). Conclusion The preliminarily prepared questionnaire of intestine and brain health has a good reliability and validity, which can be used to study the state of intestine brain health.
