Sensory processing, problem behavior, adaptive behavior, and cognition in preschool children with autism spectrum disorders.

OBJECTIVE. This retrospective study explored sensory processing characteristics in preschool-age children with autism spectrum disorders (ASD); the relationships between sensory processing and problem behavior, adaptive behavior, and cognitive function; and the differences in sensory processing between two subgroups (autism and pervasive developmental disorder-not otherwise specified). METHOD. Study measures included the Short Sensory Profile (SSP), Aberrant Behavior Checklist-Community, Vineland Adaptive Behavior Scales, and Mullen Scales of Early Learning. RESULTS. Most of the children with ASD had sensory processing challenges, and a significant relationship was found between SSP total scores and problem behavior scores; however, no significant relationships were found between SSP total scores and adaptive behavior and cognitive functioning. Although all the children had low Vineland scores, approximately one-quarter of the children had typical SSP scores. No significant differences in SSP scores were found between the subgroups. CONCLUSION. The findings highlight the importance of comprehensive evaluations for children with ASD.
