Abstract
PURPOSE: This study aimed to translate, revise, and validate the Autism Spectrum Knowledge Scale for Professional Version-Revised (ASKSP-R), used to assess the knowledge of professionals involved in autism spectrum disorder (ASD) care and services, such as such as clinicians, educators, and therapist, in the Chinese context. METHODS: The Chinese version of ASKSP-R demonstrated high internal consistency (Cronbach's α = 0.885) and strong structural validity (KMO = 0.888, RMSEA = 0.059). CFA supported a multidimensional structure, with acceptable fit indices (e.g., IFI = 0.88). IRT analysis showed suitable difficulty (-3 to +3) and discrimination (>0.5) parameters for all items. CONCLUSION: The revised ASKSP-R scale exhibited robust psychometric properties, and it can help assess the relevant knowledge of clinicians, educators, therapists, and other ASD-related professionals, enabling appropriate interventions based on assessment results, promoting targeted training and education, and increasing the rate of early diagnosis and intervention for ASD.
