Preliminary evaluation of the Chinese version of the Baby Eating Behaviour Questionnaire.

ABSTRACT

BACKGROUND: This study was conducted to develop a Chinese version of the Baby Eating Behaviour Questionnaire (BEBQ) and to evaluate its reliability and validity. METHODS: The Chinese version of the BEBQ was developed by translation and back-translation of the original BEBQ, followed by revision according to experts on the most appropriate item content. Mothers of 300 infants aged <12 months were recruited for survey participation from the paediatric outpatient departments of two large general hospitals in Xi'an, China. Fifty of the mothers were selected randomly for retesting after 2 weeks. Face-to-face surveys included explanation of the process, administration of the Chinese version of the BEBQ with regard to the exclusive breast-feeding period, and demographic data collection. The reliability, validity and discrimination of the questionnaire were evaluated through correlation coefficient calculation, factor analysis, parallel analysis and other methods. RESULTS: The Chinese version of the BEBQ consists of 15 items in four dimensions (food responsiveness, enjoyment of food, slowness in eating and satiety responsiveness). The cumulative variance contribution rate was 58.4%, the Cronbach's α coefficient was 0.93, the Guttman split-half reliability coefficient was 0.87 and the test-retest reliability coefficient was 0.75. The satiety responsiveness and food responsiveness scores differed significantly according to gestational age at birth, infant sex and average monthly weight gain (all P < 0.05). The enjoyment of food score differed significantly according to average monthly weight gain (P < 0.05). CONCLUSIONS: The Chinese version of the BEBQ showed good reliability and validity and can be used to evaluate infants' appetite through the assessment of eating behaviour.
