Autism Spectrum Disorder Reclassified: A Second Look at the 1980s Utah/UCLA Autism Epidemiologic Study
Published January 1, 2013
in Journal of Autism and Developmental Disorders
According to this study, DSM-IV-TR criteria capture more individuals with ASD and intellectual disability than DSM III criteria. The authors examined records from a statewide epidemiological study in the 80s and found that 59% of participants who were considered not autistic in the original study likely were autistic based on current DSM criteria and clinician review methods used in CDC studies.
