OBJECTIVE: Diagnostic criteria for autism spectrum disorders (ASDs) are changing with the fifth edition of the Diagnostic and Statistical Manual (DSM-5), which simplifies the diagnostic categories into social/emotional deficits and repetitive and restricted behavior. ASDs have been closely linked to a variety of other disorders, in particular externalizing disorders such as ADHD, and internalizing disorders including anxiety disorders and obsessive compulsive disorder. The present study examines the externalizing, internalizing, behavioral and adaptive symptoms of children with ASD. METHOD: Children diagnosed with the DSM-IV who do not meet diagnostic criteria for DSM-5 and were compared to a non-ASD sample and a sample of those who meet the new criteria. Differences were examined between the three experimental groups with respect to internalizing, externalizing, behavioral severity and adaptive behavior. RESULTS: No significant differences were observed between the DSM-5 and DSM-IV groups with respect to composite and subscale scores on the externalizing, behavior severity index and adaptive behavior domains of the Behavior Assessment System for Children, Second Edition. CONCLUSIONS: Significantly more impairment was evident for both ASD groups compared to the no-ASD group.
