Objective To investigate the changes of development and adaptive behavior in children with autism spectrum disorder (ASD) in different years, so as to provide theoretical basis for early identification, diagnosis and rehabilitation training of ASD. Methods The assessment results by Gesell Development Scale and S-M scores of ASD children aged 1 to 5 who were diagnosed for the first time in the Department of Child Health Care of Children's Hospital of Chongqing Medical University in 2015, 2017 and 2019 were retrospectively analyzed. Results There were no significant differences in total development quotient (DQ) of GDS and S-M scores of ASD children in the year 2015, 2017 and 2019 (F=0.920, 0.495,P>0.05). Children with ASD in different years had developmental delay(DD) on different levels, and there were significant differences in scores of DQ in gross motor area (F=9.683, P< 0.05), distribution of DQ in gross motor area and fine motor area (χ2＝22.583, 11.596, P<0.05). The DQ scores of fine motor and social behavior area of girls with ASD were higher than those of boys (Z＝2.023,2.837, P<0.05). There were significant differences in DQ and S-M score in ASD children at different age groups (H=56.557, 185.824, 37.935, 8.038, 68.752, 32.657, P<0.05). Conclusions No significant changes are seen in the level of DD and adaptive behavior for ASD children in recent five years. There are gender and age differences in the development level and social living skills of ASD children, and the retardation of gross motor development has become more and more obvious in recent years. Standardized assessment of development and adaptive behavior should be conducted as soon as possible for ASD children, and the results should be interpreted according to the gender and age of children in order to give comprehensive assessment and precise clinical intervention.
