Understanding Autism Spectrum Disorder (ASD) Assessment

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition, which can affect education, work, social life and relationships. Early and accurate autism spectrum disorder diagnosis is crucial for effective intervention and support. Indeed, early detection through accurate autism spectrum assessment improves the likelihood of positive outcomes for people with ASD as they enter adulthood.

Julian’s Autism Testing Services

Julian’s autism testing services are thorough and tailored to each individual. We use a combination of ASD assessment tools, including the Autism Diagnostic Interview Revised (ADI-R) for parents and the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) for the individual being assessed, to provide a comprehensive autism evaluation.

The ADI-R and ADOS-2 Autism Assessment Testing Tools

The ADI-R is a structured interview completed with caregiver/s of the individual undergoing assessment for autism spectrum disorder. It focuses on the individual’s behavior and development, providing valuable information for the diagnostic process.

The ADOS-2 is a diagnostic observation tool used to assess the individual directly. It involves a series of activities that allow the diagnostician to observe the examinee’s social interaction, communication, play, and imaginative use of materials. When adults are assessed using the ADOS, interview questions are integrated to assess the different autism criteria as well.

What to Expect During the Autism Assessment

Our autism assessment process is conducted at our autism evaluation center and is designed to be thorough and respectful. It involves:

1) Parent Interview (ADI-R)

To get tested for autism, a detailed interview with the parents or caregivers to gather essential background information and developmental history. Please allow for up to 3-4 hours+ for this interview. Length of interview can vary considerably depending on various factors such as the family’s circumstances, age of child and so on. It is advised that young children not attend the clinic on this day and child care arrangements be made prior.

2) Diagnostic Observation (ADOS-2)

An observation session with the individual being assessed to evaluate social interaction, communication, and behavior. The ADOS-2 involves a variety of play based activities (for younger people). For adolescents and adults there are also come interview questions throughout the ADOS in addition to aged appropriate play based activities. Parents of younger children are needed to remain present at the clinic during testing, as they can often be required at different stages of the ADOS-2.

3) Additional Information Gathering

Following the parent interview and diagnostic observation, Julian may contact other care figures, such as educators or teachers, for further insights. This is useful for gathering information about diagnostic signs and symptoms from another perspective. It also helpful for testing the criteria of whether the persons symptoms impact their ability to adapt to different settings such as school, work, social life and so forth, which is a key element of the DSM-5 definition of autism spectrum disorder.

3) Scoring and Interpretation

Julian will spend the next 2-5 weeks scoring and interpreting the results from the ADI-R and ADOS-2, incorporating all information collected into a comprehensive written report.

4) Feedback Session

The report will be made available at a feedback session approximately 2-5 weeks after the ADOS-2 session, where Julian will discuss the findings and recommendations for support and intervention.

Frequently Asked Questions (FAQs)

Q: What is the process to get tested and diagnosed for autism near me?

A: At Growth Minded Psychology, we offer comprehensive autism diagnostic evaluations. Our process involves a detailed parent interview using the ADI-R and observation using the ADOS-2.

After the ADOS session, Julian will contact other stakeholders, collate and interpret the information collected, write the report (takes 2-5 weeks), which is provided and discussed at a final feedback session at the end.

The process for adult autism assessment, can be the same as described above. However, it is understood that some cannot involve parents for whatever reason. In such cases, Julian would begin with an ADOS-2 evaluation of the adult being  assessed. Then Julian will seek out as much detail as possible about earliest signs of autism in the adults early development. This can be sought through interviewing the examinee about this. Information may be sought from loved ones, medical professionals, or previous medical records where available.
