Treatment for Higher-Order Restricted Repetitive Behaviors (H-RRB) in Children with Autism Spectrum Disorder

Restricted repetitive behaviors (RRB) are one of the core symptoms of autism spectrum disorder (ASD). Evidence suggests that higher-order RRB (H-RRB) are particularly challenging and can negatively impact family functioning (e.g., insistence on sameness, following idiosyncratic routines). The study examined the effects of a parent-implemented behavior intervention using a multiple baseline single case experimental design in three young children with ASD. The intervention involved self-management procedures and included principles of pivotal response treatment during which parents provided bids for children to vary from H-RRB and children obtained points for engaging in these other interests and activities. Results showed improvements in child behavior, parent and child affect and interactions, children’s engagement in family activities, and overall parent ratings of RRB.
