It's important to be aware of the changes to the diagnostic criteria for Autism Spectrum Disorder (ASD), and how you would go about getting an assessment and diagnosis of ASD for a child.

The previous Diagnostic and Statistical Manual (DSM) known as the DSM-IV TR classified Autism into three different diagnoses – Autistic Disorder, Asperger's Syndrome, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS).

However, in the development of the DSM-5, the American Psychiatric Association reviewed the current research and concluded that there was no evidence to support the continuation of this categorisation into three separate conditions.

Therefore, the DSM-5 has grouped these categories into one diagnosis of Autism Spectrum Disorder, and then provided further classification of the condition according to three levels of severity over two core domains i.e. 1) deficits in social communication and social interaction and 2) restricted repetitive behaviours, interests, and activities (RRBs).

A level of severity from 1 to 3 is then assessed and applied to the diagnosis for both criteria domains, with level 1 indicating a low need for support and level 3 indicating high support needs.

Here's a simple diagram of these changes below: (adapted from ASPECT Autism Spectrum Australia) DSM-IV-TR (prior to May 2013)

DSM-5

Autism Spectrum Disorders:

  • PDD-NOS/Atypical Autism 
  • Asperger's Disorder
  • Autistic Disorder
