The Relationship between Anxiety, External Structure, Behavioral History and Becoming Locked into Restricted and Repetitive Behaviors in Autism Spectrum Disorder.

Restricted and repetitive behaviors (RRBs) are central to the diagnosis of autism spectrum disorder (ASD), yet there remains a paucity of research in this domain. What is clear is that people with ASD are vulnerable to getting locked into rigid patterns of thought and behavior that contribute to a lack of adaptation. This study utilized an online survey to explore the relationship between anxiety, external structure, the measurement of RRBs and behavioral history of being locked into RRBs. A significant relationship was identified between level of anxiety and a history of becoming locked into RRBs. The likelihood of becoming locked into RRBs increased at times of decreased external structure in the routine of people with ASD.
