Autism Diagnostic Interview-Revised

The Autism Diagnostic Interview-Revised (ADI-R) is structured interview conducted with the parents of individuals who have been referred for the evaluation of possible autism or autism spectrum disorders. The interview covers the referred individual’s full developmental history, is usually conducted in an office, home or other quiet setting by a psychiatrist or other trained and licensed professional, and generally takes one to two hours. The ADOS, a companion instrument, is a semi-structured set of observations and is conducted in an office setting as a series of activities involving the referred individual and a psychologist or other trained and licensed examiner.
