Over the past few decades, there has been much debate over the different diagnoses that fall under the umbrella of autism spectrum disorders. Current views in the field of autism spectrum disorders identify three diagnoses that fall on the autism spectrum: Autistic Disorder, Pervasive Developmental Disorder, Not Otherwise Specified, and Asperger's Disorder. The aim of this study was to identify if and how children with Autistic Disorder, High Functioning, Autistic Disorder, and Asperger’s Disorder differ from one another on the Child Behavior Checklist-Parent Report form for children ages 6-18. No significant differences were found between the three diagnostic groups. This study is the first to look at behavioral differences between these diagnostic groups using the Child Behavior Checklist. The implications of the results are discussed in terms of future research, classification, and clinical utility.
