Children with autism report significantly higher rates of social
anxiety disorder (SAD) and significantly higher levels of SAD
symptomatology than the general population, but it is not clear if this is
true for adults with autism. Understanding SAD in an adult autism
population could influence screening and treatment options. This
systemic review of literature aimed to identify literature related to
whether adults with autism experience SAD at a higher rate and report
higher levels of symptomatology than the general or psychiatric
populations. A search of 5 databases returned a total of 1,369 articles,
180 of which were subjected to full-text review. Of these, 11 met
established inclusion criteria. The interpretation of results was
complicated by diverse sampling techniques, make up of comparison
groups, presentation of data and additional cultural factors, yet the
majority of the articles found evidence that adults with autism experience
SAD at a significantly higher rate and significantly higher levels of
symptoms than general psychiatric and neurotypical populations. The
current gaps in the evidence base highlight the need for improved
understanding of how SAD develops and is maintained in an adult
autism population.
