Social Communication Disorder

What Is Social Communication Disorder?

Social communication is how we use and interpret verbal and nonverbal communication with other people. It includes understanding tone and implied meaning, sharing information, and adapting a message to the listener. The social use of language is also called pragmatics.

Social communication disorder (SCD) is a specific diagnosis involving persistent difficulties in this area that affect everyday participation or relationships. A child may have strong vocabulary and grammar and still find social communication difficult; others also have additional speech or language needs. A child can need social communication support without having an SCD diagnosis.

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)
  • Difficulty adapting a message to the listener or situation
  • Difficulty making and keeping friends despite wanting social connection
  • Struggling to tell a story or explain something in a way others can follow
  • Difficulty recognising when a listener needs more information or clarification

Communication styles vary across individuals, families, and cultures. Assessment considers these differences and whether the child is experiencing difficulties in everyday communication.

Social Communication and Cognitive Communication

Cognitive communication focuses on thinking skills such as attention, memory, and organizing ideas. Social communication focuses on how a message is used and understood between people.

The two can overlap. A child may need help both remembering what was said and interpreting what the speaker meant. Therapy can address both areas when needed.

SCD vs. Autism

Social communication difficulties are a core feature of autism, but not everyone with social communication challenges has autism. Autism also involves restricted or repetitive patterns of behaviour, interests, or activities, which can include sensory differences. SCD is not diagnosed alongside autism.

Assessment considers both current communication and developmental history. Some children initially thought to have SCD may later receive an autism diagnosis as more information becomes available.

How Speech Therapy Helps

Speech therapy supports the child’s communication goals, confidence, and participation. This may include:

  • Practicing 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
  • Expressing needs and preferences, asking for clarification, and repairing misunderstandings

Therapy often involves role-playing, video modelling, and structured social activities, with skills gradually generalised to real-life settings.
