Aim: Our study utilized the Rasch Analysis to examine the psychometric properties of the Autism Behavior Checklist (ABC) in children with autism spectrum disorder (ASD).Methods: A total of 3319 children (44.77±23.52 months) were included. Rasch Model (RM) was utilized to test the reliability and validity of the ABC. The GPCMlasso Model was used to test the differential item functioning (DIF).Result: The response pattern of this sample showed acceptable fitness to RM. The analysis supported the unidimensionality assumption of the ABC. Disordered category functions and DIF were found in all items in the ABC. The participants responded to ABC item differently depending not only on autistic traits but also age groups, gender, and symptom classifications.The Rasch analysis produces reliable evidence to support that the ABC can precisely depict the clinical ASD symptoms. Difference in population characteristics may cause unnecessary assessment bias and lead to overestimated or underestimated symptom severity. Hence, special consideration for population characteristics is needed in making ASD diagnosis.
