Reliability,Validity And Evaluation Of The Intuitive Eating Scale-2 In The Nursing Undergraduates Of The Liaoning Province

ObjectiveThe study translate the intuitive eating scale-2(IES-2)into Chinese,and test the scale reliability and validity,providing references of the intuitive eating ability in the Chinese nursing undergraduates.MethodsThe Intuitive Eating Scale-2 used Brislin double translating reversion method,the intuitive eating scale-2 was translated into Chinese.With the method of multi-stage sampling,642 nursing undergraduates from three universities in Liaoning Province were selected as research objects for questionnaire survey.Reliability,validity and factors affecting of intuitive eating were analyzed by SPSS20.0,STATA15.0 and AMOS21.0.Results1、After translation and cultural adjustment of the IES-2 scale,the IES-2-CHI was finally obtained.The number of items,factor structure and distribution of each item in the scale were the same as the English original scale2、Reliability:The Cronbach’sαof IES-2-CHI was 0.944,the ICC was0.839,the split-half Cronbach’sαwas 0.926.3、Items distinction:the item-to-total correlation varied between 0.434 to0.808(P<0.05).In the discriminant validity,considering Critical Ratio value as index,and the mean score of each item was test by the independent sample t test,and the result reached significant level(P=0.000).4、Validity:In the content validity,I-CVI was from 0.830 to 1.000.The scale-level content validity index was 0.870 and the content validity index at the average scale level was 0.978.In the construct validity,four-factors model were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 71.753%.The four factor solution of IES-2-CHI had a good fit(RMR=0.028,RMSEA=0.040,AGFI=0.903,GFI=0.921,NFI=0.922,TLI=0.968,IFI=0.972,CFI=0.971,PNFI=0.816,PGFI=0.747,and x~2/df=1.523).5、Status and influencing factors:The nursing undergraduates’intuitive eating average score was 73.64±13.69.The average score of each item was3.20±0.60.Different genders,dieting and weight loss thoughts,eating speed,regular meals,frequent extra meals after meals,disturbance during meals,sleep time,BMI of the intuitive eating scores difference was statistically significant(P<0.05).ConclusionsThe Chinese version of IES-2-CHI scale has good reliability and validity among nursing undergraduates in Liaoning province,which can be used a tool to evaluate nursing undergraduates’intuitive eating status.The intuitive eating level of nursing undergraduates needs to be improved.Health education can be carried out according to different individual situations of students to guide students to establish a good diet style and living habits and improve the intuitive eating level.
