ADOS-2 Module 1

ADOS-2 Module 1 is part of the Autism Diagnostic Observation Schedule, Second Edition – widely regarded as the gold standard for assessing autism spectrum disorders (ASDs). This module is specifically designed for children aged 31 months and older who do not consistently use phrase speech.

Module 1 uses a series of structured activities and standardized scoring to assess communication, social interaction, play, and restricted or repetitive behaviors. The semi-structured nature of the protocol allows clinicians to observe natural responses while maintaining consistency and diagnostic reliability.

Benefits:

• Tailored for nonverbal children – Ideal for children aged 2.5 years and older who are not yet speaking in phrases.

• High clinical accuracy – Supports confident, evidence-based ASD diagnosis and treatment planning.

• Efficient and comprehensive – Takes just 40–60 minutes to administer, with user-friendly scoring guidance.

• Multidisciplinary use – Suitable for psychologists, speech–language pathologists, physicians, and educators.

• Supports early identification – Helps professionals detect autism symptoms early, enabling timely interventions.

Features:

• Engaging, age-appropriate activities designed to elicit behaviors that are relevant to autism diagnosis.

• Revised algorithms ensure improved sensitivity and specificity of ASD classification.

• Clear scoring protocol guides clinicians to classify as Autism, Autism Spectrum, or Non-spectrum.

• Updated Protocol Booklets provide enhanced coding instructions and improved administration clarity.

• Supports standardized, real-time observational diagnosis for reliable outcomes.
