Objective: This study aims to evaluate the validity and reliability of the Turkish version of the Child Three-Factor Eating Questionnaire for primary and secondary school students. Design: A methodological, descriptive and correlational study design was adopted. Setting: The study was conducted in the western and central regions of Turkey. Participants: This methodological-descriptive-correlational study was conducted with 351 children between July 2018 and August 2018. The mean age of children is 10·74 ± 1·79 (8-14). Results: The scale consists of seventeen items and three sub-dimensions (restraint, uncontrolled eating and emotional eating), which explained 52·88 % of the total variance. All the factor loadings were >0·40 in both exploratory factor analysis and confirmatory factor analysis (CFA). In CFA, all of the fit indices were >0·85, and root mean square error of approximation was <0·08. For the whole of the scale, Cronbach's α was 0·81 and it was found that Cronbach's α values of all sub-dimensions were >0·70. Conclusions: The results of the study show that the Child Three-Factor Eating Questionnaire for primary and secondary school students is a valid and reliable measurement tool for Turkish sampling.
