This online article briefly describes the Autism Diagnostic Interview-Revised (ADI-R), a clinical diagnostic instrument used to assess Autism Spectrum Disorder in children and adults. The ADI-R focuses on three main areas: qualities of reciprocal social interaction, communication and language, and restricted and repetitive, stereotyped interests and behaviors.

Autism Speaks describes itself as an organization “dedicated to advancing research into causes and better treatments for autism spectrum disorders and related conditions both through direct funding and collaboration; increasing understanding and acceptance of autism spectrum disorders; and working toward solutions for the needs of individuals with autism and their families across the spectrum and lifespan through advocacy and support.” [Website]
