Abstract

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and social interactions and the presence of restricted, repetitive patterns of behavior (RRBIs). The presence of RRBIs can be detrimental to a child’s development, as RRBIs can lead to impairments in other areas of functioning, impede learning, and contribute to parental stress. Previous studies have identified several factors that are associated with RRBI severity and topography. The current study aims to assess whether impairments in adaptive functioning predict RRBI severity, using the Vineland Adaptive Behavior Scales, Third Edition (VABS-3) and Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT)-Part 1, RRBI subscale score. Additionally, clinician-assigned severity levels of ASD, BISCUIT-Part 1, Childhood Autism Rating Scale, Second Edition (CARS2), and Vineland VABS-3, will be used to examine factors associated with ASD severity level. The findings of this study will provide implications for the early assessment and treatment of RRBIs in young children with ASD.
