social communication disorder
Also written as: SCD — Social Communication Disorder
A diagnostic category involving persistent difficulties with pragmatic language use in social contexts.
Full Definition
Social communication disorder (SCD) is a neurodevelopmental condition characterized by significant challenges in the social use of verbal and nonverbal communication across multiple contexts. Individuals with SCD struggle with pragmatic language skills including conversational turn-taking, topic maintenance, nonverbal communication interpretation, and adjusting communication style for different listeners and situations. The disorder affects social relationships, academic performance, and occupational functioning. Differential diagnosis must distinguish SCD from autism spectrum disorder, which includes restricted interests and repetitive behaviors alongside social communication difficulties.
