Asperger's Syndrome was introduced as a separate diagnostic category in the DSM-4 (1994). Its subsequent absorption into autism spectrum disorder in the DSM-5 (2013) led to vigorous debate and concerns about the loss of the unique Asperger's identity. Existing research has identified that adults previously diagnosed with Asperger's have expressed a diverse range of opinions regarding the DSM-5 changes. This Australian study explored the role of disability identity development in responses to the change through semi-structured interviews with 12 adults diagnosed with Asperger's under the DSM-4. Their different views did not appear to be a function of demographic variables; a connection was identified between participants' views of the change and differing stages of integration with the Asperger's and/or autism identities.
