The Development of the Food Averse Questionnaire: A Measure of Food Avoidance in Children With and Without Autistic Spectrum Conditions

Abstract

The aim of this study was to 1) develop a measure of avoidant eating behaviours for both typically developing children (TD), and those with Autism Spectrum Conditions (ASC), and 2) to examine whether these current behaviours are associated with reports of early feeding difficulties in both populations. In study one (n = 336) parents of 4- to 14-year-old children completed a series of questions about food avoidance. Three subscales of food avoidance were identified with a total scale of 31 items; avoidant, rigid-inflexible, and texture sensitive. Analyses found that scores on these subscales were associated with related measures of picky eating, food neophobia, sensory sensitivity and cognitive inflexibility, as well as lower fruit, vegetable, dairy and protein consumption. In study two, 225 children aged 4–14 years and their parents were recruited (143 TD and 78 ASC). Children with ASC were more likely to have feeding problems during the transition to family foods and in the toddler eating period in comparison to TD children. Additionally, children with ASC showed, at the time of the study, higher avoidance, rigid-inflexible eating and texture-sensitive eating behaviours than TD children. This study has developed a reliable scale for food avoidance for children with and without ASC diagnoses. Food avoidance is more severe in children with ASC than in TD children and these difficulties may start before them receiving an ASC diagnosis. Further work is needed to examine the usefulness of this scale in clinical and nonclinical populations.
