Reliability and validity of Chinese version of intuitive eating scale in college students

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 Chinese 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 item-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.
