Validation of the Adult Eating Behaviour Questionnaire adapted for the French-speaking Canadian population

Purpose:

The Adult Eating Behaviour Questionnaire (AEBQ) is a newly developed questionnaire adapted from the widely used Child Eating Behaviour Questionnaire. This questionnaire assesses four food approach scales, namely hunger, food responsiveness, emotional overeating (EOE) and enjoyment of food, and four food avoidance scales, namely satiety responsiveness (SR), emotional undereating (EUE), food fussiness and slowness in eating (SE). This study aimed to validate a French version of the AEBQ in controlled conditions among French-speaking adults from Quebec, Canada.

Methods:

The AEBQ was pre-tested through structured interviews with 30 individuals. Participants of the validation study (n = 197, aged 19–65 years) had their height and weight measured and completed the AEBQ, Three-Factor Eating Questionnaire (TFEQ) and Intuitive Eating Scale-2 to assess factorial structure, internal consistency and construct validity. Test–retest reliability over 2 weeks was assessed among 144 participants.

Results:

Confirmatory factor analysis indicated an excellent model fit (NNFI = 0.98, CFI = 0.98, RMSEA = 0.03, χ2/df = 1.17) and provided support for the use of the original 8-factor questionnaire. Internal consistency was adequate for most scales (Cronbach’s alpha = 0.66–0.94) and moderate to excellent test–retest reliability was observed for all scales (ICC = 0.70–90). Women showed higher levels of EOE and SR, and individuals with overweight and obesity showed higher levels of EOE and lower levels of EUE and SE. Construct validity was also supported by expected correlations with disinhibition and susceptibility to hunger from the TFEQ and intuitive eating.

Conclusion:

This study indicates that the French AEBQ is a valid and reliable tool to measure eating behaviours in the adult population of Quebec.

Level of evidence:

Level III: Evidence obtained from well-designed cohort or case–control analytic studies. The data are cross-sectional, but all measurement were undertaken in controlled laboratory conditions and the study provided new information.
