Abstract: Objective To explore the clinical effect of pivotal response treatment(PRT) in children with autism spectrum disorder(ASD),so as to provide reference for the rehabilitation treatment of ASD children. Methods Totally 46 children aged 2—5 years who were diagnosed with ASD in the Third Affiliated Hospital of Zhengzhou University from January 2019 to December 2019 were enrolled in the study and were randomly divided into conventional group(n=23) and PRT group(n=23). Both groups were assessed by the Autism Behavior Checklist(ABC),Childhood Autism Rating Scale(CARS) before intervention and after 3 months of intervention. Results Conventional group had obvious reductions in the total score and the scores on social interaction,somatic movement and self-care subscales of the ABC Scale after 3 months of treatment(t=5.505,3.102,3.425,4.058,P<0.05). After 3 months of treatment, the PRT group had distinct reductions in the total score and the scores on sense,social interaction,somatic movement, language and self-care subscales of the ABC Scale as well as an obvious reduction in the total score of the CARS(t=6.087,2.861,4.618,5.509,5.621,6.578,7.398,P<0.05). The PRT group had a significantly greater reduction in the total score of the ABC Scale,social interaction,somatic movement,language,self-care and the total score of the CARS Scale than the conventional group(t=8.965,5.488,3.761,5.508,2.612,5.618,P<0.05). Conclusions PRT can effectively improve social interaction,somatic movement,language and self-care of ASD children.
