Use of the ADOS and ADI-R in children with psychosis: importance of clinical judgment.
The Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview - Revised (ADI-R) are considered to be the 'gold standard' in diagnostic evaluations for autism. Developed as research tools and now gaining wide clinical use, the ADOS/ADI-R assessment package has been demonstrated to differentiate children with autism from those with other developmental disabilities; however, little work concerning the reliability and validity of the tools in children with a known history of psychosis has been undertaken. We report on the administration of the ADOS, ADI-R and clinical judgment in three cases of Childhood-Onset Schizophrenia. All 3 children met both ADOS and ADI-R criteria for an autism spectrum diagnosis, even though none of them received a clinical diagnosis of autism from either a research child psychiatrist or an experienced clinically trained, research psychologist with expertise in autism. Issues concerning overlap of symptom presentation and implications for research and clinical use of these assessment tools are discussed.
