The ASD diagnosis was based on DSM‐5(American Psychiatric Association, 2013), combined with the Autism Diagnostic Interview‐Revised (ADI‐R; Lord, Rutter, & Couteur, 1994) and Autism Diagnostic Observation Schedule (ADOS) (Lord et al., 2000). In addition, the overall intelligence level of all children was estimated by Peabody Picture Vocabulary Test (PPVT) (Dunn, Dunn, & Arribas, 2006). The Social Responsiveness Scale (SRS) was also applied to estimate their ability to engage in emotionally appropriate social interactions (Constantino, 2002). The Autism Spectrum Quotient Children's Version (AQ‐child; Baron‐cohen, Wheelwright, Skinner, Martin, & Clubley, 2001) is suitable for 4–11 years old children with autism screening. The items in this scale were divided into 5 dimensions, including social skills, attention switching, attention to detail, communication, and imagination. Each item was scored with 0–3 points and 4 grades. The total score of the scale was 0–150. The higher the total score, the more serious the autistic symptoms were.
