Research measuring sensory processing in children with autism spectrum disorder (ASD) has shown variability in terms of measures used and participant ages, contributing to difficulty in interpreting and summarizing the findings of these studies. In an attempt to clarify the status of the literature, we conducted a systematic review of studies that focused on participation in daily occupations and evaluated sensory processing in children with ASD aged 5–13 yr using Dunn's sensory processing framework. Evidence from 7 studies shows that sensory processing has a significant impact on participation in daily life of children with ASD. Included studies demonstrated medium and low levels of evidence. Additional research using more robust scientific methods is needed.
