title: Parent-Reported Repetitive Behavior in Toddlers on the Autism Spectrum.
abstract: Toddlers with autism spectrum disorder (ASD) were assessed on the Repetitive Behavior Scale-Revised (RBS-R), which we found to have acceptable internal consistency. Stereotypical subscale scores showed a negligible association with cognitive level, but correlated more strongly with adaptive and social indicators. Relative to earlier reported RBS-R scores for older age groups, toddlers' scores trended toward higher stereotyped behavior and lower ritualistic/sameness behavior. Our findings on associations with developmental indicators align with those of researchers who used more resource-intensive repetitive behavior measures. The convergence of these findings with those derived from other measurement methods suggests that the RBS-R, a cost effective parent-report measure, is a viable means of assessing repetitive behavior in toddlers with autism.
