Autism spectrum disorder (ASD) is characterized by a core deficit in social communication with concomitant repetitive/perseverative behaviors and restriction in interests,1 and individuals with ASD experience varying degrees of impairment.2 The estimated prevalence of ASD in pediatric populations has climbed dramatically during the past decade, with approximately 1 in every 68 children currently meeting diagnostic criteria in the United States.3 High prevalence occurs against a backdrop of increased health care costs4 and social burden.
