Adult Autism Assessments: What to Expect

If you or a loved one is considering an autism assessment for an autism diagnosis but feeling overwhelmed about where to start, this guide is here to provide clarity on the process and what you can anticipate.

Autism Assessment & Diagnosis Process for Adults

Clinical History/Interview

The assessment process usually begins with some exploration of your background, encompassing health, development and significant events. Assessors will inquire about your primary symptoms of concern during this phase.

Formal Assessment

Following the background examination, the assessor conducts a thorough assessment to delve deeper into your symptoms. Two commonly used assessments are the ADOS-2 (Autism Diagnostic Observation Schedule-Second Edition) and the MIGDAS-2 (Monteiro Interview Guidelines for Diagnosing Asperger’s Syndrome).

The ADOS-2 is a practical assessment that provides a controlled environment for an assessor to observe symptoms of Autism and can be particularly valuable for those uncertain about how their symptoms impact them.

The MIGDAS-2 is a flexible semi-structured interview, which is preferable for those well-acquainted with their symptoms.

At PsychWest, we currently use the ADOS-2 for both child and adult assessments.

After the main assessment, your assessor may screen for additional conditions that could influence your symptoms, such as ADHD, CPTSD (complex post-traumatic stress disorder), or mood disorders.

References

Assessors often seek input from family, partners or close friends to gather observations. References can be provided in person using the ADI-R or a semi-structured interview, over the phone or in written form. School reports can serve as supplementary information for adults.

Report and Feedback

After gathering information, your assessor should compile this into a report and provide a feedback session.  This session aims to address next steps, potential funding options, and answer any questions you may have.

Who can diagnose autism?

Psychologists or psychiatrists who have had relevant training and experience with autism can diagnose and provide support through the assessment process. If you are seeking assessment, ensure that you let the practice know so that they can direct you to the correct practitioner and you can start the assessment process right away.

It is recommended that you research the assessment processes of available practitioners to make an informed decision. PsychWest is currently accepting appointments for autism assessments and combined autism/ADHD assessments.

What should I do now?

Given the typical waiting lists for autism assessments, take this time for reflection. Whether awaiting an assessment date or contemplating the need for assessment, consider how autism might explain your history and current symptoms.

Embarking on an autism assessment journey can be daunting, but understanding the process and being informed about available resources will help you navigate this important step toward understanding and support.
