Adult Autism Assessment & Diagnosis 

What Does an Autism Assessment at ClinPsych Consulting involve? 

Whether you are on the Autism or combined Autism/ADHD assessment pathway, an Autism assessment comprises a structured observation of, and interaction with, the individual in the clinic and includes an interview about emotions, social difficulties & annoyances, and friends & relationships, a self-report developmental history and, where possible, an interview with an informant for their perspective on developmental history.

This assessment process ensures a holistic understanding of the client’s strengths and challenges and is designed to provide valuable insights into the individual’s unique profile, aiding in the development of targeted strategies and interventions for optimal support whether an Autism diagnosis is given or not.

An Autism assessment will usually follow the below steps:

 Part 1 – Initial screening:

This is an initial screening assessment to help establish whether it is appropriate for the individual to undergo full diagnostic assessment. It is a general neurodevelopmental screen meaning that Autism as well as ADHD can be considered, as needed. Consideration will also be given to mental health. The initial assessment usually comprises of an appointment lasting up to 1.5 hours during which the clinician will explore the presenting issues and conduct a concise developmental history. If required, screening measures will be administered. 

As part of this assessment, the clinician will discuss with you whether there are enough considerations regarding Autism to warrant full diagnostic testing. You will then need to confirm whether you wish to proceed to step 2 of the assessment. 

Part 2 – Full diagnostic assessment:

This is the diagnostic part of the assessment process. It will usually comprise an appointment where standardised tests are completed using ‘gold standard’ diagnostic tools. Our part 2 assessments will involve a multidisciplinary team in order that professionals can agree on a diagnosis. 

As part of the assessment, close relatives or partners can be invited to provide background information, with the agreement of the client. Part 2 of the assessment process usually takes up to 4 weeks to complete. 

The composition of assessments varies between clients, including some or all of the following:

  • Assessment of communication and social interaction (ADOS-2 or MIGDAS-2)

  • Structured in-depth developmental and adult-life history (ADI-R)

  • Review of existing professional reports (if available)
