The Children's Eating Behaviour Questionnaire (CEBQ) was developed to assess eight dimensions of eating style in children: responsiveness to food, enjoyment of food, satiety responsiveness, slowness in eating, fussiness, emotional overeating, emotional undereating, and desire for drinks. The questionnaire was developed through a combination of existing literature and parent interviews, and was refined using data from three samples of families (N=131, N=187, N=218). The final 35-item instrument had good internal consistency and test-retest reliability. The CEBQ was validated for use in research on the early precursors of obesity and eating disorders, particularly in relation to the heritability of obesity. The study found minimal gender differences in eating style, with satiety responsiveness and slowness in eating decreasing with age, while enjoyment of food and food responsiveness increased. The CEBQ provides a reliable and valid measure of eating style for research into the development of obesity and eating disorders. The study highlights the importance of assessing eating style before obesity develops, as eating patterns may be influenced by weight control efforts once obesity has occurred. The CEBQ is a useful tool for investigating the role of eating style in the development of obesity, particularly in relation to genetic factors. The study also notes that further research is needed to establish the predictive validity of the CEBQ.The Children's Eating Behaviour Questionnaire (CEBQ) was developed to assess eight dimensions of eating style in children: responsiveness to food, enjoyment of food, satiety responsiveness, slowness in eating, fussiness, emotional overeating, emotional undereating, and desire for drinks.
