Abstract
Research on the repetitive behavior of children diagnosed with autism spectrum disorder (ASD) has recently gained scholarly attention. Restricted and repetitive behavior (RRB) is a core ASD symptom of various patterns and high prevalence. The Repetitive Behavior Scale-Revised (RBS-R) is a standard questionnaire used to assess RRB in individuals with ASD. This study collected data from 163 Chinese children aged 3-8 with ASD to analyze the validity and reliability of the RBS-R. Results showed that the original tested items were adaptable to the Chinese cultural environment when treating such disorders. A confirmatory factor analysis was applied to the structuring models, indicating that a 5-factor model was more suitable for evaluating RRB in this context.
