Not much is known at present about the behavioural and sensory profiles of children with avoidant/restrictive food intake disorder (ARFID), the newest addition to the eating disorder diagnostic category in DSM-V. Our aims were to examine eating difficulties, behavioural problems and sensory hypersensitivity in ARFID children, relative to typically developing children with no reported feeding, mental or physical health problems, as well as children with autistic spectrum disorders (ASD; typically associated with a high prevalence of eating problems) or Picky Eating (PE).
