Service impact

by  /  29 June 2012

One persistent concern is how the changes might affect access to services for people with the disorder. For example, critics of the DSM-5 say they worry the new criteria will push some people off the spectrum, making it more difficult for them to gain access to special-education services and other support.

The Autistic Self Advocacy Network (ASAN), a national community organization run for and by adults on the autism spectrum, released a report in early June on how the new criteria will influence eligibility for special education, Social Security and other programs.

The verdict: Although there are some areas for concern, the changes are mostly good.

For example, some states specifically exclude people with Asperger syndrome or PDD-NOS from mandated services, a distinction that can no longer be made under the DSM-5. So these people may benefit from the changes.

However, the report also suggests that if some people, particularly those diagnosed as having PDD-NOS, do not meet diagnostic criteria for autism, they will lose their access to services. 

Under the DSM-5, people who have trouble with social communication but don’t meet the full diagnostic criteria for autism would be diagnosed with social communication disorder. The precise definition of this alternative diagnosis is not yet clear, nor is it apparent how those who mediate access to services, such as state governments and schools, will interpret it.

One possibility ASAN proposes is to include social communication disorder within autism, calling it ASD–Social Communication subtype or something similar. That way, laws that explicitly mention autism would still apply to this group.

If indeed a significant number of people diagnosed with PDD-NOS move to a diagnosis of social communication disorder, are they impaired enough to require legally mandated services? That’s a question that should be answerable empirically.

At least one clinician who works with this group says the answer is yes. “In our experience, people with a PDD-NOS diagnosis often miss out on a full diagnosis due to a lack of restrictive and repetitive behaviors,” William Mandy, lecturer in clinical health psychology at University College London, told me at the conference in May. “But I think a lot of them have profound communication difficulties on a level with autism.”
