What Does An Assessment Involve?
An ASD assessment usually comes in two parts:
Part 1 is an initial assessment to help establish whether it is appropriate for the individual to undergo full diagnostic assessment. The initial assessment usually comprises of an initial appointment lasting up to 1.5 hours during which a history of difficulties will be taken and screening measures administered. Following this, the clinician will discuss with you whether there are enough concerns associated with ASD to warrant full diagnostic testing- if so, you will then need to confirm whether you wish to proceed to Part 2 of the assessment (diagnostic assessment).
Part 2 usually comprises of several clinic-based appointments where standardised tests are completed, including the ADOS-2 (Autism Diagnostic Observation Schedule – 2nd edition) which is well established as part of the ‘gold standard’ method of diagnosing autism. Additional assessments often include administration of the ADIR (Autism Diagnostic Interview- Revised) to family members, cognitive/intellectual assessment and school-based observations (in the case of child clients). Our assessments will usually involve more than one clinician in order that professionals can concur on a diagnosis. Our clinicians are all highly skilled and work hard to help children and adults alike feel at ease during the assessment process. Assessments are paced to the individual and rest breaks will be given where needed. Usually we find that clients quite enjoy the process, particularly liking some of the activities involved in the ADOS.
