Factor structure and psychometric properties of the Child Feeding Questionnaire in Australian preschool children.

The Child Feeding Questionnaire (CFQ) is a widely used measure of parental feeding practices, comprising seven factors that measure aspects of parental control over feeding and beliefs about children's obesity proneness. Parents in South Australia (N=203) completed the CFQ at their 4- or 5-year-old child's preschool health visits in May and June 2006. This study examined the factor structure and psychometric properties of the questionnaire. Initially, exploratory factor analysis (EFA) was used to examine the factor structure of the CFQ. Using EFA an additional factor could be extracted, comprising 2 items from the Restriction subscale regarding parents' use of food to reward behaviour. Several modified seven factor models of the CFQ, specified in previous research, were examined using confirmatory factor analysis and compared with an eight factor model. An eight factor model specifying an additional factor, food as reward, provided the best fit to the data, however, until replicated and validated, a seven factor model excluding the reward items is recommended for general use. The findings suggest that further work is required in the conceptualization of the Restriction subscale.
