The Effects of Severity of Autism and PDD-NOS Symptoms on Challenging Behaviors in Adults with Intellectual Disabilities

摘要

Autism Spectrum Disorders (ASD) constitute a group of neurodevelopmental conditions that result in marked delays and impairments. The ASD can be defined by a good deal of heterogeneity and severity of specific behaviors within the general domains of communication, social behavior, and repetitive/stereotyped behavior. ASD also puts the afflicted individual at risk for other problems such as intellectual disability and challenging behaviors. This study assessed the relationship between severity of ASD core symptoms and the rate and types of challenging behaviors evinced in 298 adults with severe intellectual disabilities (ID). General categories of aggression/destruction disruptive behavior, and self-injury were studied. More severe core ASD symptoms were associated with higher rates of challenging behaviors. The implications of these findings are discussed.
