Reliability and validity of Chinese version of intuitive eating scale in college students / 中华行为医学与脑科学杂志

ABSTRACT

Objective To translate the English version of the Intuitive Eating scale-2( IES-2) into Chinese,and test the reliability and validity of the Chinese version of IES-2(IES-2-CHI) in college students. Methods The reliability and validity of the Chinese version of IES-2 were tested among 1 309 college students in Liaoning province. All data were analyzed by SPSS 20. 0 and AMOS 21. 0. Results The Chi-nese version of IES-2-CHI, all inter-items and item-to-total correlation coefficients ranged from 0. 444 to 0. 759. The IES-2-CHI had a total Cronbach’s α of 0. 933 and the test-retest correlation was 0. 831. The i-tem-level content validity index(I-CVI)ranged from 0. 830 to 1. 000,the scale-level content validity index(S-CVI/UA)was 0. 870,and the content validity index at the average scale level(S-CVI/Ave)was 0. 978. Four-factors(unconditional permission to eat,eating for physical rather than emotional reasons,reliance on hunger and satiety cues,body-food choice congruence) model were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 58. 974%. The confirmatory factor analysis results showed that χ2/df=2. 941,CFI=0. 959,GFI=0. 920,TLI=0. 954,PGFI=0. 747,RMSEA=0. 055,and the model was basically adaptable. Conclusion The Chinese version of IES-2-CHI scale is reliable and valid instrument, which can be used to measure the level of intuitive eating among the college students in Liaoning province.
