Diagnosis
for Adults
It’s not uncommon for someone to receive a diagnosis of Autism in adulthood.
Not as much was known about Autism over 30 years ago. While diagnostic testing has improved for younger children, our medical community still struggles to identify adults with Autism.
Because Autism characteristics are becoming more known to the general population, more undiagnosed adults are recognizing that Autism may explain their significant life-long experiences and struggles.
The Autism Society Inland Empire has compiled this toolkit to answer some of the common questions we receive. Click on the graphic for the pdf version, available free to download. We also have a confidential support group for adults diagnosed later in life or seeking a diagnosis that usually meets once a month. Check our calendar for the next meeting date.

Receiving a medical diagnosis is a personal decision and is based on different factors such as your financial resources and if you will be pursuing government services such as employment, social security, etc. To learn more about getting diagnosed as an adult, read this helpful article and scroll below to the section on getting diagnosed as an adult: Getting an Autism Spectrum Diagnosis / The Diagnostic Process.

On-Line Autism Tests
There are also several free online tests you can take that may indicate whether you are on the Autism spectrum or not. Please note that these online tests do not take the place of a professional diagnosis and only indicate that you may be on the Autism spectrum.
RDOS—Aspie-Quiz:
https://rdos.net/eng/Aspie-quiz.php
According to the websitehttps://rdos.net/eng/Aspie-quiz.php, this test aims to check for broader Autism cluster
(Aspie) and neurotypical traits in adults. Broader Autism clusters traits can
give a reliable indication of Autism spectrum traits before an eventual
diagnosis.
The Ultimate Autism Resource:
https://embrace-autism.com/
Provides additional Autism tests and assessments worth taking a look at.
The Ritvo Autism Asperger Diagnostic Scale-Revised (RAADS-R):
https://www.aspietests.org/raads/
According to the website, The RAADS-R is a modified version of the Ritvo
Autism Asperger’s Diagnostic Scale (Ritvo et al. 2008). The rationale for its
development was the need for a clinical adjunct diagnostic tool. While
several diagnostic scales for children and adolescents with ASD are
available, only one peer-reviewed scale, The Autism-Spectrum Quotient
(AQ) was designed specifically for adults. Its authors emphasize that it is
useful in identifying Autistic traits and as a screening instrument but not
as a diagnostic tool.
