Translation and validation of the Child Three-Factor Eating Questionnaire (CTFEQr17) in French-speaking Canadian children and adolescents

Objective: To translate and validate the Child Three-Factor Eating Questionnaire (CTFEQr17), assessing cognitive restraint (CR), uncontrolled eating (UE) and emotional eating (EE), among French-speaking Canadian young individuals. Design: Phase 1 comprised a translation and the evaluation of the comprehension of the questionnaire. Phase 2 comprised a confirmatory factor analysis (CFA), the evaluation of internal consistency (Cronbach's alpha), test-retest reliability (intra-class correlation coefficients (ICC)) and construct validity, including correlations among the CTFEQr17 and Eating Attitudes Test (EAT-26), anthropometrics, dietary intake and diet quality. Setting: Primary and secondary schools, Quebec City, Canada. Participants: Phases 1 and 2 included 20 (40 % boys, mean age 11 center dot 5 (sd 2 center dot 4) years) and 145 (48 % boys, mean age 11 center dot 0 (sd 1 center dot 9) years) participants, respectively. Results: Phase 1 resulted in the questionnaire to be used in Phase 2. In Phase 2, the CFA revealed that the seventeen item, three-factor model (CTFEQr17) provided an excellent fit. Internal consistency was good (Cronbach's alpha: 0 center dot 81-0 center dot 90). Test-retest reliability was moderate to good (ICC = 0 center dot 59, (95 % CI 0 center dot 48, 0 center dot 70), ICC = 0 center dot 78, (95 % CI 0 center dot 70, 0 center dot 84), ICC = 0 center dot 50, (95 % CI 0 center dot 38, 0 center dot 62) for CR, UE and EE, respectively). CR correlated with EAT-26 score (r = 0 center dot 43, P < 0 center dot 0001). UE and EE correlated negatively with BMI Z-scores (r = -0;center dot 26, P = 0 center dot 003; r = -0;center dot 19, P = 0 center dot 03, respectively). CR correlated with the proportion of energy intake from protein and diet quality (r = 0 center dot 18, P = 0 center dot 04; r = 0 center dot 20, P = 0 center dot 02, respectively). Conclusion: The CTFEQr17 is suitable to use among French-speaking Canadian young individuals.
