The study aimed to identify the effectiveness of a training program using sensory integration to reduce sensory processing disorder and its effect on echolalia in children with autism spectrum disorder, and the research was applied on a sample of (12) children, their chronological ages ranged between (6-9) years with an average age of (7.75) ) And a standard deviation (1.21), and they were divided into two equal groups, the first experimental and the second control, each of them consisted of (6) children, and the study tools included the Stanford scale - interstitial intelligence (fifth image) (Taqnin: Mahmoud Abu Al-Nile, 2011). Gilliam for the Diagnosis of Autism (Taqnin: Muhammad Abd al-Rahman and Mona Hassan, 2004), Sensory Processing Disorder Scale prepared by: Barrios-Fernández et al. (2020), the researcher's translation, echo scale (preparation: the researcher), and the training program using sensory integration, and the results of the study resulted in the effectiveness of the training program using sensory integration in reducing the disturbance of sensory processing and resonance among the members of the experimental group in the post application compared to the control group and also compared with The pre-application of the experimental group, and it also resulted in no statistically significant differences between the post and tracer measurements of the experimental group.
