Abstract: Objective: To translate the Social Inclusion Scale (SIS), and to test its reliability and validity among parents of children with Autism Spectrum Disorder (ASD). Methods: The original English version of SIS was translated and back-translated according to the Brislin model. The Chinese version of the scale was finalized after cultural adaptation and pretest on the scale. A total of 679 parents of children with ASD aged 3 to 14 years old in 33 special children's rehabilitation institutions in Hunan Province were investigated from July 2023 to January 2024 to test the reliability and validity of the Chinese version of SIS. Results: There were 19 items in the Chinese version of SIS, the Item-level Content Validity Index (I-CVI) was 0.83 to 1.00, the consensus Scale-level Content Validity Index (S-CVI/UA) was 0.8, and the average Scale-level Content Validity Index (S-CVI/Ave) was 0.908. The exploratory factor analysis identified four factors, and the cumulative variance contribution rate was 57.973%. The confirmatory factor analysis showed that χ2/df=2.456, RMSEA=0.066, GFI=0.904, AGFI=0.873, PNFI=0.727, PGFI=0.682, IFI=0.913, CFI=0.912, which indicated that the fitting degree of each index was good. Conclusion: The Chinese version of SIS has good validity and reliability, and can be used to evaluate the social inclusion of parents of children with ASD in the context of Chinese culture.
