Abstract
OBJECTIVES
To examine the frequency of repetitive behaviors among children with autism spectrum disorder (ASD) and compare it to age-matched developmentally delayed (DD) and typically developing children (TD).
METHODS
Twenty-five children (3-8 y) with a diagnosis of ASD were compared to two age-matched control groups namely the DD and TD groups. The Repetitive Behaviors Scale-Revised (RBS-R) was administered to the parents to assess the frequency, severity, and impairment associated with restricted, repetitive behaviors, and interests (RRBIs) displayed. The study was cleared by the institute ethics committee.
RESULTS
The three groups were well matched on age and sex distribution and comparisons on the RBS-R showed that the ASD group had a significantly higher total score (F = 51.52, p = 0.0001) and number of items endorsed on the scale (F = 37.91, p = 0.0001). Stepwise multiple regression analysis revealed that 35.8% of the variance in the total RRBI score of the ASD children was explained by the age and severity of autism (F = 6.12. p = .008). Older children with severe ASD features had significantly higher total RRBI scores.
CONCLUSIONS
RRBIs are not just specific to autism and should not be used in isolation to identify children with autism. Gaining a complete understanding of the complexity and variability of the restricted interests would help in improving the diagnostic procedures and in the development of a comprehensive therapeutic plan.
