The Autism diagnostic service is available for adults and young people aged 16 and above. Our assessments will be conducted by our fully trained clinicians; from the professions of Psychology, Speech and Language Therapy, Psychiatry, Occupational Therapy, and Psychiatric Nursing.  

Benefits of having an Autism diagnostic assessment

Families report that by having better understanding of their child’s behaviour, they are able to find helpful strategies and different ways to engage and communicate with their child.

For adults the outcome is one of relief, they talk about finally understanding why they had difficulty holding down a job or making relationships. A huge burden is lifted. This is much the same if the assessment results in Autism not being diagnosed. Knowing that can result in different options being explored.

Autism Diagnostic Assessment Tools

The diagnostic assessment tools used for identifying Autistic Spectrum Conditions are the ADOS 2 (use with the individual) and ADI-R (used with parents/carers).

The ADOS 2 assessment looks at the social interaction between the assessor and the individual the social interaction between the assessor and the individual. It consists of a series of table top tasks that takes between 30 and 60 minutes. There are no invasive procedures involved, and there are no blood tests or tissue samples taken. It is very helpful if the ADOS 2 assessment is video recorded in order to enable the assessor to revisit the assessment prior to writing the report.  
The Autism Diagnostic Interview-Revised (ADI-R) is a structured interview conducted with someone who has known the individual closely since early childhood. In the case of a child being assessed, this will be the parent or caregiver. For adults being assessed this would preferably be a parent or care giver, but it may be possible to carry this out with an older sibling or other relative.   The ADI-R takes between 2 and 3 hours to complete, again it is very helpful if this interview is video recorded. The interview covers the referred individual’s full developmental history. 

A report of the clinical findings will be written and presented to the participant (if they are adult) or the participant’s parent in the case of a child, and a second copy of the report will be presented to the referring authority if that is appropriate.
