A comparative study of sensory processing in children with and without Autism Spectrum Disorder in the home and classroom environments

•We assessed the sensory profile in children with ASD and children with typical development.•Home and main classroom contexts were compared, and differences were found.•In the home environment, hearing was the most affected. Touch was the least affected.•In the classroom environment, touch and hearing were the most affected.•It is proposed to reduce unpredictable auditory and tactile inputs at classroom. Sensory processing and higher integrative functions impairments are highly prevalent in children with ASD. Context should be considered in analyzing the sensory profile and higher integrative functions. The main objective of this study is to compare sensory processing, social participation and praxis in a group of 79 children (65 males and 14 females) from 5 to 8 years of age (M=6.09) divided into two groups: ASD Group (n=41) and Comparison Group (n=38). The Sensory Processing Measure (SPM) was used to evaluate the sensory profile of the children: parents reported information about their children's characteristics in the home environment, and teachers reported information about the same characteristics in the classroom environment. The ASD Group obtained scores that indicate higher levels of dysfunction on all the assessed measures in both environments, with the greatest differences obtained on the social participation and praxis variables. The most affected sensory modalities in the ASD Group were hearing and touch. Only in the ASD Group were significant differences found between the information reported by parents and what was reported by teachers: specifically, the teachers reported greater dysfunction than the parents in social participation (p=.000), touch (p=.003) and praxis (p=.010). These results suggest that the context-specific qualities found in children with ASD point out the need to receive information from both parents and teachers during the sensory profile assessment process, and use context-specific assessments.
