Validity and reliability of Turkish version of the Adult Eating Behaviour Questionnaire for adult participants

Objective: The aim of this study is to assess the validity and reliability of the Adult Eating Behaviour Questionnaire (AEBQ-TR) for adults. Design: Hunot et al. (2016) developed the original questionnaire, which was modified and translated into Turkish. On data collected from adults, construct validity was assessed using exploratory factor analysis and confirmatory factor analysis. Pearson's and Cronbach's correlation coefficients were used to evaluate reliability and validity (P < 0 center dot 05). Setting: This research was carried out in Ankara, Turkey. Participants: A total of 311 adults from Ankara (148 men and 163 women) took part in the study. Seventy-two of these adults take the retest. Results: In the present study, 311 adults with a mean age of 29 center dot 3 +/- 11 center dot 3 years participated. Factor loadings ranged from 0 center dot 404 to 0 center dot 907. In general, food approach and food avoidance scales showed a positive correlation within themselves. According to the results of confirmatory factor analysis and goodness-of-fit indicators, the seven-factor model showed a better model fit in the Turkish data (chi-square/degrees of freedom = 2 center dot 137, root mean error of approximation: 0 center dot 061, comparative fit index: 0 center dot 884, and normed fit index: 0 center dot 850). Higher BMI was associated with higher Emotional Over-eating, higher Enjoyment of the Food, lower Food Satiety and lower Emotional Under-eating. Conclusions: The Turkish AEBQ is a valid and reliable tool for 20- to 65-year adults to determine appetitive properties related to the aetiology of weight change and especially obesity risk. Besides, AEBQ testing is required for validation in early and late adulthood.
