BACKGROUND: Children with autism spectrum disorder (ASD) and other developmental disabilities (DD) exhibit sensory features that differ from their typically developing peers. Prior cross-sectional research has demonstrated significant associations between elevated sensory features and lower adaptive behavior scores, yet there is limited prospective research examining longitudinal associations.AIMS: To examine the longitudinal prediction of early sensory response patterns (i.e., hyperresponsiveness, hyporesponsiveness, and sensory interests, repetitions, and seeking behaviors) to later adaptive behavior outcomes in children with ASD and DD.METHODS AND PROCEDURES: Children with ASD (n = 51) and DD (n = 30) were seen at two time points (Time 1: M(SD) = 5.6(2.5) years; Time 2: M(SD) = 9.0(2.2) years). We used a series of regression models with both observational and parent-report measures of sensory response patterns, and including group interactions.OUTCOMES AND RESULTS: All three sensory response patterns significantly predicted aspects of adaptive behaviors, with some differences based on assessment format and diagnostic group. Across groups and sensory patterns, we found some evidence that elevated sensory features early in childhood predicted lower adaptive behavior skills later in childhood.CONCLUSIONS AND IMPLICATIONS: Sensory features may interfere with development of adaptive behaviors, suggesting a need for effective interventions addressing sensory features early in development.
