Autism Diagnostic Interview, Revised (ADI-R)

ADI-R is a 93-item interview that helps diagnose autism in children and adults with a mental age over 18 months. In most cases, the interview lasts for 1.5 to 2.5 hours, including scoring. The interview is standardized and administered by a trained clinician to parents or caregivers of the child with suspected autism.

The interview includes items within three areas, including:

  1. Communication
  2. Reciprocal social interactions
  3. Restrictive, repetitive, and stereotyped behaviors

The interview also determines the onset of abnormal behaviors, to determine if the child meets age of onset criteria.
