Full Definition
The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is a semi-structured assessment that provides standardized contexts for observing social communication behaviors associated with autism spectrum disorder. The assessment consists of structured activities and interactions designed to elicit behaviors relevant to autism diagnosis across different developmental levels and chronological ages. The ADOS-2 is considered the gold standard for autism assessment and is often used in conjunction with developmental history and other clinical information to make diagnostic determinations.
Usage
Usage note: Distinguish from ADI-R, which is a structured parent interview rather than direct observation.
