An exploration of the association between matrix reasoning and eating disturbance behavior in girls with autism spectrum disorder

Background: Although there have been suggestions that central coherence may be associated with eating disturbances (EBD) in children with autism spectrum disorder (ASD), relatively little attention has been given to specific aspects of IQ and EDB. Methods: The association between total IQ, perceptual and verbal composite scores and subtests was explored in a sample of 50 high-functioning girls with ASD (mean age = 9.7 years, SD = 2.4 years, range = 6 years to 14 years). Self-reports and mothers’ reports were collected about the girls’ EDB. Results: There were only isolated associations between mothers’ data and the girls’ IQ. Selected aspects of the girls’ self-reported EDB were significantly associated with matrix reasoning. Conclusion: The role of IQ, particularly matrix reasoning, in the assessment and treatment of EDB in girls with ASD, is highlighted by these findings.
