Comorbid psychopathology rates in children diagnosed with autism spectrum disorders according to the DSM-IV-TR and the proposed DSM-5.

Objective: To investigate differences in comorbid psychopathology rates between individuals who meet criteria of Autism Spectrum Disorders (ASDs) according to DSM-5 or the DSM-IV-TR.

Methods: Comorbid psychopathology was measured using the Autism Spectrum Disorders- Comorbid for Children. 424 individuals between the ages of 2 and 18 years of age; including children who met criteria for an ASD according to the DSM-5, the DSM-IV-TR only, and a control group that did not meet either set of criteria.

Results: Of the ASD participants, 36% would no longer meet criteria according to proposed DSM-5. Comorbidity rates for the ASD groups were significantly different from the control group; however, ASD groups were not significantly different in terms of total comorbid psychopathology.

Conclusion: The results elucidate the need for further research regarding services and treatments for those individuals that will no longer meet criteria for an ASD but still have significant rates of comorbid psychopathology.
