The DSM-5 diagnostic criteria for Autism Spectrum Disorder (ASD) placed a new emphasis on the clinical presence of restricted and repetitive behaviors (RRB). There is little research exploring the relationship between RRB and other patient characteristics in large well-characterized samples. This study used a comprehensive measure of RRB to determine how RRB relate to key demographic and clinical features such as gender, age, IQ, adaptive behavior, and problem behaviors. In addition, it examined the relationship between different RRB measures, and how these RRB measures relate to the severity of social communication (SC) symptoms. Data from the Simons Simplex Collection (SSC) were used to address these research aims. Correlations, ANCOVA, and logistical regressions were conducted using a sample of 2,759 children with ASD. Analyses revealed varying relationships between RRB and gender, IQ, and problem behaviors. Males were more likely to obtain higher scores on subscales measuring stereotypy and restricted interests. Across full-scale, nonverbal, and verbal IQ, individuals with lower IQ scores were more likely to be reported to have higher rates of all RRBS with the exception of ritualistic/sameness behaviors. Most problem behavior subscales were significantly related to all RRB measures except for the ADOS RRB scores. Results from the regression analyses suggest that overall RRB symptom measures differ in their ability to predict SC criteria. Implications for the current literature, understanding and diagnosis of ASD are discussed and directions for future research suggested.
