Exploring the effect of motor coordination on repetitive behaviours in children with autism spectrum disorder

Objective: This study was conducted to explore the effect of motor coordination on repetitive behaviors in children with Autism Spectrum Disorder (ASD) aged 5-15 years. Methods: The study employed the causal-comparative design, one of the correlational survey designs. The study was carried out with data obtained from parents of 241 children with ASD. The parents were administered the measurement tools of Gilliam Autism Rating Scale-2-Turkish Version to confirm the diagnosis of ASD, Demographic Information Form to obtain information about the child and the parent, Repetitive Behavior Scale-Revised-Turkish Version to evaluate the repetitive behaviors, and Developmental Coordination Disorder Questionnaire-07-Turkish Version to evaluate the motor coordination performance. The data were analyzed MANCOVA in the R package program. Results: The study results revealed that 72% of children with ASD had a risk of Developmental Coordination Disorder (DCD). The repetitive behaviors of children with and without DCD risk differed significantly. The severity and intensity of the repetitive behaviors of children with DCD risk were higher than those without DCD risk when age, gender, and comorbidity were taken under control. Conclusion: The motor coordination problems in children with ASD are effective on repetitive behaviors.
