RESUMEN
OBJECTIVE: To investigate the development of social skills in children with autism spectrum disorder (ASD) and related influencing factors. METHODS: A total of 889 children with ASD in 10 cities of China were enrolled as subjects. The Autism Social Skills Scale was used to assess their social skills. RESULTS: The children with ASD had a lower score of each factor than the theoretical median, with the lowest score for social communication and the highest score for self-regulation. There were significant differences in the total score of social skills and the scores of social cognition and social participation between the children with ASD in different age groups (P<0.05). There were also significant differences in the total score of social skills and the scores of social orientation, social communication, social participation, and self-regulation between the ASD children with different language levels (P<0.01). CONCLUSIONS: Children with ASD have low social skills, and their social skills are associated with age and language level.
