Changes in Autism Nosology: The Social Impact of the Removal of Asperger's Disorder from the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5)

This study examined the perception of an ASD label compared to Asperger's syndrome or no diagnosis. Seventy-one undergraduates read an adapted vignette (Ohan et al. J Autism Dev Disord 45:3384-3389, 2015) about an undergraduate with ASD, Asperger's Syndrome, or No Diagnosis. Participants also completed questionnaires. More positive ratings emerged for the Asperger's and ASD labels than No Diagnosis in low contact scenarios, particularly when involving greater social versus professional interaction. In contrast, more positive ratings emerged for the Asperger's compared to the ASD and No Diagnosis on high contact items. Ratings between low and high contact items differed only for ASD. Results demonstrate the impact of diagnostic labels across social contexts and support the need for education surrounding changes in nosology.
