Comparison of Two Tools to Assess Sensory Features in Children With Autism Spectrum Disorder.

OBJECTIVE: This article documents the convergent validity of the Sensory Profile (SP) and the Sensory Processing Measure (SPM)-Home Form for children with autism spectrum disorder (ASD). METHO: . Parents of 34 children with ASD between ages 5 and 8 yr filled out both measures. Through correlations, χ² tests, and levels of agreement between classifications, the results for the SP and the SPM-Home Form were compared. RESULTS: The raw scores were correlated for some sensory domains (hearing, vision, touch, and proprioception) and for social functioning. The classifications showed a significant level of agreement for most scales (κs = .247-.589, p ≤ .05) and for the total scores (κ = .324, p ≤ .01). CONCLUSION: This study provides further evidence of convergent validity between both tools. The SPM-Home Form identifies more children with ASD who present with sensory features for every domain measured by both tools.
