Social Communication Disorder
What Is Social Communication Disorder?
Social communication disorder (SCD) is a condition where a child has difficulty with the social use of language, also known as pragmatics. Children with SCD understand words and grammar but struggle with the way language is used in real-life social interactions.
This might look like difficulty reading body language, taking turns in conversation, staying on topic, understanding sarcasm or humour, or adjusting the way they speak depending on who they are talking to.
Signs of Social Communication Disorder
- Difficulty following the flow of a conversation (topic maintenance, turn-taking)
- Trouble understanding nonverbal cues (facial expressions, tone of voice, body language)
- Taking language very literally (missing sarcasm, jokes, or implied meaning)
- Not adjusting language for the situation (speaking the same way to a teacher as to a friend)
- Difficulty making and keeping friends despite wanting social connection
- Struggling to tell a story or explain something in a way others can follow
- Misreading social situations, responding in ways that seem off or unexpected
SCD vs. Autism
Social communication difficulties are a core feature of autism, but not everyone with social communication challenges has autism. SCD is diagnosed when a child has significant pragmatic language difficulties without the restricted interests, repetitive behaviours, or sensory differences associated with autism spectrum disorder.
Some children initially thought to have SCD may later receive an autism diagnosis as more information becomes available, so ongoing monitoring is important.
How Speech Therapy Helps
Speech therapy for SCD focuses on building the social language skills that do not come naturally. This may include:
- Practising conversation skills: starting, maintaining, and ending conversations
- Learning to read and respond to nonverbal cues
- Understanding perspective-taking and how others may think or feel
- Using language flexibly across different settings and listeners
- Building narrative skills to tell clearer, more organised stories
- Developing strategies for navigating group interactions at school
Therapy often involves role-playing, video modelling, and structured social activities, with skills gradually generalised to real-life settings.
Frequently Asked Questions
- What is social communication disorder?
- Social communication disorder (SCD) is a condition where a child has persistent difficulty using language in social contexts — including understanding nonverbal cues, taking turns in conversation, adjusting language for different listeners, and following the unspoken rules of communication. Unlike autism, SCD does not include restricted or repetitive behaviours.
- How is social communication disorder different from autism?
- Both autism and SCD involve challenges with social use of language. The key difference is that autism also includes restricted interests, repetitive behaviours, or sensory sensitivities. A child with SCD has social communication difficulties without these additional features.
- Can social communication disorder be treated?
- Yes. Speech-language pathologists use structured and naturalistic approaches to help children develop social communication skills — including reading social cues, understanding perspective, managing conversations, and using language flexibly across settings. With consistent support, children make meaningful progress.
