Brief Report: Characterization of Sensory Over-Responsivity in a Broad Neurodevelopmental Concern Cohort Using the Sensory Processing Three Dimensions (SP3D) Assessment.

The report is an interim analysis of a larger ongoing study, so the numbers may not represent the final cohort. The sample was small, especially the ASD subgroup with 13 children, so estimates for children with ASD may be imprecise. The paper reported a significantly male-skewed sex difference between the ASD and non-ASD groups. The cohort was largely White, non-Hispanic or non-Latin American, and had high parental education and income, so findings may not apply to more diverse communities. Children with nonverbal IQ at or below 70 were excluded, so it does not describe children with more severe cognitive impairment. Three participants were not classified as ASD or non-ASD because additional in-person testing could not be done during the pandemic.

The supplied text names the National Institute of Health as the funder and does not provide an author conflicts of interest statement.

Do not conclude that sensory over-responsivity is specific to autism. In this sample, the proportion with auditory or tactile over-responsivity was similar in children with and without an ASD research designation, and the ASD group had only 13 children.
