The Autism Diagnostic Interview-Revised (ADI-R) and its companion instrument the Autism Diagnostic Observation Schedule (ADOS-2) are the internationally recognised ‘gold standard’ assessment tools for the diagnosis of autism spectrum disorder. The ADI-R and the ADOS-2 both cover the social, communication and repetitive features associated with autism spectrum disorder.
The ADI-R interview provides the clinician with a detailed picture of your child’s development, including their behaviours and social interactions from early childhood to the present day.
The ADOS-2 involves a series of structured and semi-structured tasks which vary according to your child’s age and language level. They provide ‘presses’ for social interaction with the examiner. The ADOS-2 can be used with children as young as age 12 months. However we advise that for a more accurate diagnostic assessment, your child should be older than 3 years of age.
Both the ADI-R and ADOS-2 can be undertaken with adults of any age.
Our assessments are carried out/analysed by two clinicians. This ensures that we provide a consensus diagnostic opinion. Our assessment process is NICE compliant.
