Adult Autism Assessment

Are you worried that you have Autism Spectrum Disorder (ASD) and you do not want to wait several months to see a specialist? Have you always felt ‘different’ to other people and would like to know if there is a reason for this?

The Autism Service can complete a diagnostic assessment with you. The outcome of this will either be a diagnosis of ASD or confirmation that you do not have ASD. The diagnostic assessment we offer is thorough and based on several years' experience, plus knowledge of relevant guidance and research.

We understand what works and what does not work in terms of completing reliable diagnostic assessments. There are no short-cuts and less robust assessments are more likely to result in diagnoses being missed or people being incorrectly diagnosed.

  • Our diagnostic assessment consists of:
  • Clinical interview, including taking a developmental history
  • Direct observation of your communication and interaction skills in clinic
  • Review of information from informants (in person or via reports)
  • Diagnostic discussion by assessing team
  • Feedback meeting with you

We use the best available tools – ADOS-2 and when appropriate ADI-R – to do our assessment and you will always be seen by more than one clinician.

The fee for a diagnostic assessment for an adult is £1495. This includes a report and advice, and a dedicated point of contact or keyworker during the assessment process.

It is a pleasure to be able to sit down with a person who has felt different their entire life and struggled daily and tell them that they have autism. It explains so much for them. The diagnosis is empowering and allows them to start a new relationship with themselves – a healthier and more compassionate one.
