ADOS-2 Upgrading Workshop

ADOS-2 is a semi-structured, standardized assessment of communication, social interaction, play/imaginative use of materials and restricted and repetitive behaviours for individuals who have been referred because of possible autism spectrum disorder (ASD). Fundamentally new to the ADOS-2 than ADOS-G are the procedures involved in the algorithm computation and the Comparison Score for Module 1 through 3 which were revised on the basis of the findings of recent validation research. The new Comparison Score provides a way of indicating a participant’s level of autism spectrum related symptomatology and it can also be used to interpret an individual’s own change in autism spectrum related symptoms over time. ADOS-2 also includes a Toddler Module, which is designed for very young children who do not use phrase speech but who are between the ages of 12 and 30 months. The Toddler Module has its own algorithms that provide “ranges of concern” instead of cutoff scores. A variety of specialists will use the ADOS 2, their use of results in writing reports and making recommendations to inform medical diagnoses, special education classification and occupational therapists and speech and hearing professionals might use for treatment planning.

The half-day ADOS-2 Upgrading Workshop for clinicians is now available through the Department of Psychiatry, Trinity College Dublin.

Interested participants should have PREVIOUSLY COMPLETED ADOS training in TCD or elsewhere.

This course is most useful to professionals who are using ADOS in their clinical practice.
