(ADOS®-2) Autism Diagnostic Observation Schedule, Second Edition

Allows you to accurately assess and diagnose autism spectrum disorders across age, developmental level, and language skills.

Like its predecessor, the ADOS-2 is a semi-structured, standardized assessment of communication, social interaction, play, and restricted and repetitive behaviors. By observing and coding these behaviors, you can obtain information that informs diagnosis, intervention, treatment planning, and educational placement.

The Most Accurate Picture of Current ASD Symptoms
With improved algorithms, the ADOS-2 demonstrates strong predictive validity. It gives you a highly accurate picture of current ASD-related symptoms, based on real-time observations. Physicians, clinical psychologists, school psychologists, speech–language pathologists, and occupational therapists can use ADOS-2 results to inform diagnosis, intervention, educational placement, and treatment planning. Because it can be used with a wide range of children and adults, the ADOS-2 is an essential addition to any hospital, clinic, or school that serves individuals with developmental disorders.

AGES: 12 months through adulthood

(ADOS®-2) Autism Diagnostic Observation Schedule, Second Edition This revision improves an instrument already viewed as the “gold standard” for observational assessment of autism spectrum disorders (ASDs). With updated protocols, revised algorithms, a new Comparison Score, and a Toddler Module, the ADOS-2 provides a highly accurate picture of current symptoms, unaffected by language. It can be used to evaluate almost anyone suspected of having ASD—from 1-year-olds with no speech to adults who are verbally fluent.
