The Autism Diagnostic Interview-Revised (ADI-R) is an instrument for collecting the in-depth developmental history of individuals at or beyond the developmental level of 2 years. ADI-R is used for diagnosing autism and planning treatment by trained examiners. ADI-R focuses on the following domains: 1) social interaction, 2) communication, and 3) range of restrictive, repetitive, and stereotyped behaviors.
