ASD Assessment

Lloyd Counseling offers a comprehensive evaluation and assessment for children and adults to determine Autism Spectrum and related diagnoses better.

Autism Diagnostic Observation Schedule (ADOS-2)

The Autism Diagnostic Observation Schedule (ADOS-2) is a standardized assessment tool to aid a psychologist in diagnosing Autism Spectrum Disorder (ASD) in children and adults.

Unlike many other psychometric tools, the ADOS-2 is administered in the form of a semi-structured social setting for standardized behavioral observation and coding instead of a paper-and-pen tool or an electronic assessment.

Frequently Asked Questions

What Happens during an Autism Diagnostic Observation Schedule (ADOS-2) Assessment?

ADOS-2 comprises of the following:

  • Semi-structured Interview(s)
  • Administration of an ADOS-2 Module (40 – 60 minutes)
  • After the Assessment, a Feedback Session to explain the findings and recommendations
What does an Autism Diagnostic Observation Schedule (ADOS-2) measure?

The ADOS-2 has standardized activities and questions, such as planned social activities, which include events where social situations, communication, and behaviors are likely to appear. These provide the psychologist an excellent opportunity to observe behaviors directly relevant to an ASD diagnosis.

The Autism Diagnostic Observation Schedule (ADOS-2) measures:

  • Communication
  • Social interaction
  • Play
  • Restricted and repetitive behaviors
How does this work?

Suitable for children and adults, the ADOS-2 has five modules depending on one’s age language and developmental level, as listed below. Each module takes 40 to 60 minutes, and an individual only goes through one module. The module they undergo is based on their communication level and age.

What are the modules?

Toddler Module – for children between 12 to 30 months who do not consistently use phrase speech.

Module 1 – for children above 31 months who do not consistently use phrase speech
Module 2 – for children of any age who use phrase speech but are not verbally fluent
Module 3 – for verbally fluent children and young adolescents
Module 4 – for verbally fluent older adolescents and adults

What do the modules assess?

These modules are similar in assessing areas in communication, social interaction, play, and restricted and repetitive behaviors. By observing and coding these behaviors, information can be attained for diagnosis, management planning, and educational placement.

Where an official ASD diagnosis is sought, psychologists use the ADOS-2 in tandem with the Autism Diagnostic Interview-Revised (ADI-R). The combination of ADI-R and ADOS-2 allows for a more comprehensive and accurate understanding of your family member’s condition and what can be done to support them best moving forward.
