Investigating variables which predict the presence and severity of aggression and self-injurious behavior in children with autism spectrum disorder
Abstract
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Literature indicates that individuals diagnosed with autism spectrum disorder (ASD) are at-risk for developing challenging behaviors (Holden and Gitlesen, 2006; McClintock et al., 2003). Challenging behaviors such as aggression and self-injurious behavior (SIB) warrant additional attention due to the negative impacts associated with the presence of these behaviors. The purpose of the current study was to investigate variables which predict the presence and severity of aggression and self-injurious behavior (SIB) in a large sample (n = 2100) of children with autism spectrum disorder (ASD). According to results of regression analyses, the presence of lethargy/social withdrawal behavior, irritability, and hyperactivity/noncompliance were predictive of aggressive behavior in this sample. Irritability and hyperactivity/noncompliance also predicted severity of exhibited aggressive behavior. Older age and the presence of inappropriate speech, irritability and aggression were predictive of SIB in this population. Irritability also predicted severity of exhibited SIB. Implications for research and practice are discussed.
