Full Definition
The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is a semi-structured, standardized assessment tool used to diagnose autism spectrum disorders across different ages and developmental levels. The assessment involves structured activities and interactions that allow trained clinicians to observe and code behaviors related to social interaction, communication, and restricted and repetitive behaviors. The ADOS-2 provides different modules based on the individual's expressive language level and chronological age, making it applicable from toddlers to adults. Results are combined with developmental history to support diagnostic decision-making.
