October 5 and 6, 2021

Registration Now Open!

Please Note

This two-day workshop will be presented via Zoom. All participants are required to have their own copies of ADOS-2 protocols (Modules 1-4) during the training in order to score the ADOS-2 while watching videos of administration and participate in scoring discussions. These protocols can be purchased via Western Psychological Services. Participants may find it useful to bring an ADOS-2 manual to the training as a reference (not essential).

Workshop Overview

ADOS-2 is a gold standard diagnostic tool used to help assess Autism Spectrum Disorder (ASD).  The ADOS-2 is a widely used and well validated direct observation tool used in the diagnostic assessment of autism spectrum disorders (ASD). The administration of the four modules of the ADOS-2 will be outlined. (Note: Toddler module not included.) Video demonstrations of some of the modules will be shown and used in order to discuss scoring criteria in detail.

The ADOS-2 requires clinical experience with ASD and other neurodevelopmental disorders, as well as previous training and experience in assessment. It is recommended that attendees undertake as many practice opportunities with the ADOS-2 as possible after attending the workshop in order to use the ADOS-2 reliably for clinical or other purposes.

 Goals and Objectives

• To develop familiarity with the ADOS-2 as a diagnostic tool.
• To learn about the standardized administration of the ADOS-2.
• To practice scoring the ADOS-2 based on video demonstration.
• To learn about the interpretation and reporting of ADOS-2 results.

Who Should Attend

This workshop is designed for professionals such as school/clinical psychologists, speech language pathologists, or others who are involved in the diagnostic assessment of children or adults who may have an autism spectrum disorder. (This program will not provide advanced training for those interested in using the instrument for research purposes.)

I thought this training was excellent, and I'm not one to love training/professional development in general. The material was so practical and applicable.
