There have been changes in criteria for the diagnosis of autism from the fourth edition of the diagnostic and Statistical Manual of Mental Disorders (DSM-IV) to the DSM-V. The changes from the DSM-IV to the DSM-V include the combination of the subgroups Asperger’s syndrome and not other specified (PDD-NOS) into one autism spectrum disorder category (Hoogenhout & Malcolm-Smith, 2014). The changes were made because there was not enough evidence to support the differences, which led to problems with research but the study by Hoogenhout and Malcolm-Smith (2014) supports that the DSM-5 was more successful in determining the Theory of Mind development beyond intellectual functioning.
The new criteria to diagnosis ASD states that the following four criteria must be met (Justice & Redle, 2014):
- Symptoms of ASD must develop during childhood
- The symptoms of ASD must affect an individual’s everyday functioning
- The symptoms must include problems with social communication and social interaction (for example, problems with participating in and initiating conversations)
- The symptoms must include restricted and repetitive patterns of behavior (example, fixed interests and repetitive behaviors)
