Parent-Reported Repetitive Behavior in Toddlers on the Autism Spectrum.
The parent RBS-R is a quick, trustworthy way to measure repetitive behaviors in toddlers with autism.
01Research in Context
What this study did
Parents filled out the Repetitive Behavior Scale-Revised (RBS-R) for toddlers with autism.
Researchers checked if the scores lined up with other child development measures.
What they found
The RBS-R gave steady results across items and matched developmental indicators.
It is a cheap, quick way to track repetitive behaviors at home.
How this fits with other research
Mirenda et al. (2010) already showed the RBS-R works in preschoolers; this study pushes the age down to toddlers.
Day et al. (2021) later found the same four-factor structure fits both autism and ADHD groups, so the scale travels across diagnoses.
Carati et al. (2024) fed RBS-R scores into neural networks and uncovered hidden links between sensory issues and repetitive acts, showing the data can do double duty.
Koegel et al. (2014) warned that broad behavior checklists miss autism flags; the RBS-R, built only for repetitive behaviors, avoids that trap.
Why it matters
You can hand the RBS-R to parents during intake and get reliable data before the child turns three. Use it to set baseline levels, pick first targets like stereotypy or insistence on sameness, and show progress every six months without extra clinic time.

03Original 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.
