An Autism Spectrum Disorder (ASD) diagnosis is often used to access services. We investigated whether ASD diagnostic outcome varied when DSM-5 was used compared to ICD-10R and DSM-IV-TR in a clinical sample of 150 intellectually able adults. Of those diagnosed with an ASD using ICD-10R, 56 % met DSM-5 ASD criteria. A further 19 % met DSM-5 (draft) criteria for Social Communication Disorder. Of those diagnosed with Autistic Disorder/Asperger Syndrome on DSM-IV-TR, 78 % met DSM-5 ASD criteria. Sensitivity of DSM-5 was significantly increased by reducing the number of criteria required for a DSM-5 diagnosis, or by rating 'uncertain' criteria as 'present', without sacrificing specificity. Reduced rates of ASD diagnosis may mean some ASD individuals will be unable to access clinical services.
