The American Psychiatric Association has proposed major revisions for the diagnostic category encompassing Autism Spectrum Disorders (ASD), which will reportedly increase the specificity and maintain the sensitivity of diagnoses. As a result, the aim of the current study was to compare symptoms of ASD in children and adolescents (N = 208) who met criteria for ASD according to only the "DSM-IV-TR" to those who met criteria according to the forthcoming version of the "DSM" and to those that were typically developing. Participants comprising the "DSM-IV-TR" and "DSM-V" groups did not score significantly different from each other on overall autism symptoms, but both groups scored significantly different from the control group. However significant differences emerged between the "DSM-IV-TR" and "DSM-V" groups in the core domain of nonverbal communication/socialization. Implications of the results and the proposed changes to the ASD diagnostic category are discussed. (Contains 2 tables.)
