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.

目的：本研究旨在探讨运动协调对 5-15 岁自闭症谱系障碍 (ASD) 儿童重复行为的影响。

方法：本研究采用因果比较设计，相关调查设计之一。该研究是根据从 241 名自闭症儿童的父母那里获得的数据进行的。父母使用Gilliam Autism Rating Scale-2-Turkish Version的测量工具来确认 ASD 的诊断，人口统计信息表以获取有关孩子和父母的信息，重复行为量表-修订版-土耳其版本以评估重复行为和发育协调障碍问卷-07-土耳其语版，用于评估运动协调能力。在 R 包程序中对数据进行了 MANCOVA 分析。

结果：研究结果显示，72% 的自闭症儿童有发展协调障碍 (DCD) 的风险。有和没有 DCD 风险的儿童的重复行为有显着差异。在控制年龄、性别和合并症的情况下，有DCD风险的儿童重复行为的严重程度和强度高于无DCD风险的儿童。

结论：自闭症儿童运动协调问题对重复行为有效。
