Abstract: Objective To analyze the adaptive behavior characteristics of children with low-functioning autism spectrum disorder (ASD) in different age groups,so as to provide guidance for the education of ASD children. Methods A total of 71 children with low-functioning ASD from Shanghai Minhang special school were enrolled in this study,and were divided into 4-≤8 years old and >8-12 years old groups.Adaptive behaviors of the children were assessed via the Chinese version of Vineland Adaptive Behavior Scales(VABS) in ASD.Standard scores of four domains of VABS were obtained,including communication,daily living skills,socialization and motor skills.And the difference on the scores of the four domains was compared between the two groups. Results The 4-≤8 years old group had the highest standard score in motor skills(75.40±11.43),followed by communication (60.20±11.58).The standard scores with the poorest results were in daily life skills (57.60±4.96) and socialization (56.70±6.25).However,the standard scores of motor skills,communication,daily life skills and socialization in >8-12 years old group were 70.70±13.21,55.10±8.62,53.40±7.27 and 53.10±4.40,respectively.T test results indicated that the differences on communication,daily life skills and socialization,except for motor skills,were significant(t=2.13,2.91,2.66,P＜0.05). Conclusions Socialization and daily life skills are the two worst domains in low-functioning ASD children,followed by communication.Moreover,deficits in socialization,daily life skills and communication become more evident with increasing age.While motor skill is a relative strength in low-functioning ASD children.
