Objectives: To review the effect of proposed DSM V diagnostic algorithms on the diagnostic outcome of a clinical sample of patients assessed for ASD in adulthood.
Methods: Diagnostic information was reviewed for 100 consecutive adult patients who attended the Behavioural Genetics Clinic, a specialist clinic providing assessment of ASD at the Maudsley Hospital, London. Original diagnosis was made in accordance with the ICD-10 criteria. Diagnostic assessment included a detailed neuropsychiatric interview, Autism Diagnostic Interview-Revised (ADI-R) and / or Autism Diagnostic Observation Schedule (ADOS) pending consent to contact parents/parental availability and physical examination. Information from the ICD 10 algorithm, ADI-R, ADOS and neuropsychiatric assessment reports was used to recode diagnostic outcomes in accordance with the proposed DSM 5 ASD algorithm as posted by the American Psychiatric Association.
Results: Data will be presented showing the degree of agreement between current ICD 10 diagnoses (Asperger’s Syndrome, Childhood Autism, Atypical Autism, Pervasive Developmental Disorder-not otherwise specified) and the proposed new DSM 5 diagnosis of ASD.
Conclusions: Implications for proposed changes to diagnostic criteria will be highlighted.
