Family accommodation occurs frequently among families of children with OCD and anxiety disorders, with higher levels of accommodation repeatedly associated with greater symptom severity, lower functioning, and poorer treatment outcomes for children. This is the first examination of family accommodation of restricted and repetitive behaviors (RRBs) in children with autism spectrum disorder (ASD). Parents of children with ASD (N = 86) completed questionnaires assessing their children’s RRBs and parental accommodation of these symptoms. Most participants (80%) reported engaging in accommodation at least once a month and family accommodation was significantly positively correlated with RRB severity. These results suggest accommodation of RRBs follows a pattern similar to that reported in obsessive compulsive and anxiety disorders, and highlight avenues for potential parent-based interventions.
