Autism Diagnostic Observation Schedule

From Wikipedia, the free encyclopedia

The Autism Diagnostic Observation Schedule (ADOS) is a standardized protocol created in 1989 for assessing social and communicative behavior associated with autism. The protocol consists of a series of structured and semi-structured tasks that involve social interaction between the examiner and examinee. The examiner observes the subject's behavior and assigns identified segments to predetermined observational categories. Categorized observations are subsequently combined to produce numerical scores. Research-determined cut-offs identify the likely presence of autism or related autism spectrum disorders, allowing a standardized assessment of autistic symptoms. The ADI-R, a companion instrument, is a structured interview conducted with the parents of the referred interview and covers the full developmental history of the referred individual.

The ADOS cannot be used for formal diagnosis with individuals who are blind or deaf or who have other serious sensory or motor disorders such as cerebral palsy or muscular dystrophy.
