Autism Spectrum Disorder (ASD) Assessments

What is ASD?

Autism Spectrum Disorder is a neurodevelopmental condition that exists on the continuum of neurodiversity. Individuals with ASD may have different ways of experiencing the world compared to neurotypical people and have their own unique strengths and challenges. Some of the strengths associated with ASD include a great attention to detail, ability to understand patterns and mathematics, a deep interest in certain topics, and a unique perspective on the world. Challenges associated with ASD can include difficulty with social communication and interaction, sensory processing differences, and a need for routine and predictability.

How is ASD assessed?

Assessments of ASD are a complex process and usually involve paediatric assessment (for children) or psychiatrist assessment (for adults) along with allied health assessments. A Neuropsychological assessment can assist with the diagnosis of ASD in both adults and children.

Neuropsychological assessments of ASD in children involve an interview and observation of the child, as well as the completion of various standardised cognitive tests of functioning. A parent or caregiver will also be interviewed to determine the developmental and medical history and child’s current functioning. Questionnaires will also be completed by parents and teachers where possible. And background documents will be requested including school report cards, reports from other allied health and any previous assessment reports.

Assessments of ASD in adults also involve an interview and cognitive testing with the client. We will also aim to collect collateral information from a significant other regarding the client’s current functioning and history. Questionnaires will also be given to the client and a significant other. And background documents will be requested such as school reports and allied health assessment reports.

The aims of the assessment are to determine if ASD symptoms are present, and to assess whether the symptoms are not better explained by another psychological or physical condition. If the ASD criteria are met, the severity of symptoms will also be assessed from mild to severe. An important goal is to also understand what the client’s strengths are, to inform a strength-based approach to treatment planning. Also, the assessment will help pin-point areas where support may be required and what type of supports or interventions might be helpful.

What is involved in an ASD Assessment?

ASD assessments typically take between 5 and 6 hours to complete, comprising of 3-4 hours of testing with the child or adult, and 2-3 hours of interviews with the client, parent and/or loved one. A detailed report will be provided that includes the background and testing information and diagnostic opinion, as well as recommendations.

A formal feedback session can also be booked after the report is finalised so that the results of the assessment and report can be reviewed in more detail.
