Results: The RBQ-2 was found to be a reliable measure of these behaviors at this age and revealed a high frequency of particular types of repetitive motor movements in 15-montholds.Conclusion: These findings have implications for the early detection of disorders characterized by high levels of restricted and repetitive behaviors, such as Autism Spectrum Disorder (ASD).

Aberrant Development of Speech Processing in Young Children with Autism: New Insights from Neuroimaging Biomarkers

“…Dsm-5 Task Force, 2013). Individuals with ASD show a reduced interest in socially relevant stimuli (McPartland et al, 2011; Pelphrey et al, 2011; Chevallier et al, 2012; Kohls et al, 2012), tend to avoid eye-contact with their immediate surrounding (Senju and Johnson, 2009; Elsabbagh et al, 2012; Jones and Klin, 2013), and show repetitive behaviors and restricted interests (Turner, 1999; Watt et al, 2008; Arnott et al, 2010). Moreover, affected children often present language delay, with deficits in expressive and receptive language skills (Hudry et al, 2010; Eigsti et al, 2011; Mody et al, 2013; Simms and Jin, 2015).…”

Repetitive Behavior and Restricted Interests in Young Children with Autism: Comparisons with Controls and Stability Over 2 Years

“…RRBs are not specific to ASD; these behaviors are observed in typically developing children [Arnott et al, 2010;Barber, Wetherby, & Chambers, 2012;Evans et al, 1997] and among individuals with other developmental and psychiatric disorders, but it is the degree of excess and resulting impairment that appears specific to ASD. Studies have found that ASD can be differentiated from other disorders based on the type and severity of the RRBs presented [Bodfish, Symons, Parker, & Lewis, 2000;Mandy, Charman, Gilmour, & Skuse, 2011].…”

The Feasibility and Validity of Autism Spectrum Disorder Screening Instrument: Behavior Development Screening for Toddlers (BeDevel)—A Pilot Study

“…Insistence on Sameness/Adherence to Routines/Restricted Patterns of Behavior were only significant in the 36-42 month group and not for the younger groups, and Restricted, Fixated Interest was not significant, despite the fact that those are recognized as important diagnostic features of ASD. One possible explanation is that such behaviors can be observed in the developmental trajectories of both TD and DD children at a young age, and some children with mild ASD do not display RRBs [Arnott et al, 2010;Evans et al, 1997]. -Nevertheless, because children diagnosed with ASD often display more severe RRBs during infancy and toddlerhood compared to children with TD and DD, and because it remains stable over time, careful evaluation of RRB through parental interviews and child observation remains necessary [Joseph, Thurm, Farmer, & Shumway, 2013;Kim & Lord, 2010;Richler, Huerta, Bishop, & Lord, 2010;Watson et al, 2007].…”
