Investigation of the relationships between sensory processing disorders, daily living skills and activity participation in children diagnosed with autism spectrum disorder with repetitive behavior

Our study aims to investigate the relationships between sensory processing disorders, daily living skills, and activity participation in children diagnosed with Autism Spectrum Disorder (ASD) who exhibit repetitive behaviors. This study addresses a gap in the literature concerning the link between repetitive behavior and sensory processing issues related to motor planning, daily living skills, and modulation. The sample of our research consists of 62 children, aged 4 to 7 years, diagnosed with ASD and residing in Istanbul. The diagnosis of ASD in these children was made by a Child and Adolescent Psychiatrist in accordance with DSM-V criteria. Data collection tools included the Dunn Sensory Profile (DP), SCOPE, Repetitive Behavior Scale (TEDÖ-R-TV), Pediatric Disability Assessment Inventory (PÖDE), Developmental Anamnesis, SIPT Kinesthesia Test, and Clinical Observation of Postural Movement. Statistical evaluation of the data employed Pearson correlation analysis. Additionally, the Mann-Whitney U test was utilized to assess the significance of differences in SPIT scores between autistic children and typically developing children. The findings revealed no significant negative relationship between repetitive behaviors and the behavioral outcomes of sensory processing associated with reduced extensor muscle control in children with ASD. Moreover, the study illustrated that sensory processing skills impact daily living skills and activity participation in ASD children. The outcomes of the research can be summarized under the following headings: ''Significant associations were identified between sensory processing disorders and daily living skills in children with ASD, indicating challenges in daily living skills for those with sensory processing issues.'' ''Among autistic children, stereotypic behaviors, self-injurious behaviors, and restricted behaviors were observed. These behaviors negatively influenced the daily living skills and functionality of autistic children.'' ''Motor skills were found to be associated with sensory processing abilities, movement regulation, and the organization of visual inputs. Motor skill levels could affect sensory processing abilities in autistic children.''
