Objective: To translate the Eating Disorder Core Beliefs Questionnaire (ED-CBQ) into Chinese and to test its reliability and validity. Method: The Chinese version of the ED-CBQ was developed through translation, back-translation, cross-cultural adaptation, and a pilot survey. A convenience sampling method was used to select 497 college students for a questionnaire survey to test the reliability and validity of the Chinese version of the ED-CBQ. Results: Exploratory factor analysis yielded a five-factor structure including self-loathing, dependence, inhibition, perfectionism, and abandonment, and confirmatory factor analysis showed that the five-factor model fit well (CMIN/DF = 2.2, IFI = 0.903, TLI = 0.895, RMSEA = 0.049); the scale had good discriminant and convergent validity; Conclusion: The Chinese version of the ED-CBQ has good structural validity, internal consistency reliability, and high discriminability, and can be used to assess the core beliefs of eating disorders in the Chinese college student population.
