Abstract
Background
We aimed to determine whether there was a decrease in the number of children diagnosed
on the autism spectrum after the implementation of the new diagnostic criteria as
outlined in the Diagnostic and Statistical Manual of Mental Health Disorders Fifth
Edition published in May 2013.
Method
We reviewed 1552 charts of children evaluated at the Women and Children's Hospital
of Buffalo, Autism Spectrum Disorders Clinic. A comparison was made of children diagnosed
with autism spectrum disorder (autism, Asperger disorder, pervasive developmental
disorder–not otherwise specified) from 2010 to May 2013 using the Diagnostic and Statistical
Manual of Mental Health Disorders Fourth Edition, Text Revision criteria with children
diagnosed from June 2013 through June 2015 under the Diagnostic and Statistical Manual
of Mental Health Disorders Fifth Edition.
Results
Using χ2 analysis, the 2013-2015 rate of autism spectrum disorder diagnosis (39%) was significantly
lower (P < 0.01) than the 2010 to May 2013 sample years rate (50%).
Conclusion
The rate of autism spectrum disorder diagnosis was significantly lower under the recently
implemented Diagnostic and Statistical Manual of Mental Health Disorders Fifth Edition
criteria.
