Which characteristic distinguishes autism spectrum disorder from social communication disorder according to DSM-5 criteria?

Autism spectrum disorder (ASD) is characterized by a distinct set of features, one of the most prominent being the presence of repetitive and restrictive patterns of behavior. This aspect is specifically outlined in the DSM-5 criteria for diagnosing ASD, where behaviors may include repetitive movements, insistence on sameness, or highly focused interests that differ significantly from typical development.

In contrast, social communication disorder focuses primarily on the challenges individuals face in social communication without the presence of the restrictive or repetitive behaviors that are hallmark traits of ASD. Therefore, while individuals with social communication disorder may struggle with understanding and navigating social interactions, they do not exhibit the same repetitive behaviors found in those diagnosed with autism spectrum disorder.

This differentiation is significant in tailoring interventions and support for individuals, ensuring that those with ASD receive the full spectrum of help they need not just for communication, but also for managing the unique aspects of their behavioral patterns. Thus, the characteristic of repetitive and restrictive behavior is key in distinguishing ASD from other communicative disorders like social communication disorder.
