Presently, the DSM is undergoing revision in anticipation of the publication of the DSM-5 in 2013 (APA, 2010a). The Neurodevelopmental Disorders DSM-5 workgroup has suggested that Asperger’s Disorder (AS) and Autistic Disorder (AD) be subsumed into a new, Autism Spectrum Disorder (ASD) diagnosis (APA, 2010b). This project reviews researcher methodologies for the description, study inclusion/exclusion, and assessment of individuals with AS and AD in 100 highly cited articles from high-impact journals. Results demonstrate that researchers’ methodologies are highly variable. Additionally, all researchers do not use the “gold standard” combination of the ADOS and the ADI-R for assessing AS and AD. The use of inconsistent and potentially inappropriate methodologies in the literature suggests it may be preemptive to base the proposed DSM-5 revision on the incomparable results in the research.
