Social Communication Difficulties: ICD-11 Features
Social Communication Difficulties (ICD-11 6A01.22) is a persistent impairment in the pragmatic, social use of language disproportionate to structural language and cognition, diagnosed only when autism's restricted/repetitive behaviours are absent. Early-childhood features span reciprocity, context adaptation, narrative inference and non-verbal integration.

The child who speaks in full sentences yet cannot hold a conversation is often the one whose difficulty is missed longest.
In short
Social Communication Difficulties (ICD-11 6A01.22, a sub-category of Developmental Speech or Language Disorders) describes a persistent impairment in the pragmatic, social use of verbal and non-verbal communication that is disproportionate to the child's structural language and general cognitive ability. Crucially, it is diagnosed only when the restricted, repetitive behaviours of autism are absent — distinguishing it from autism spectrum disorder. Onset is in the developmental period and the difficulty limits everyday social participation.
The science, briefly
In early childhood, ICD-11 features cluster across the pragmatic domain rather than phonology or grammar:
- Reciprocity — difficulty initiating, sustaining and repairing back-and-forth exchanges; poor turn-taking.
- Context adaptation — failure to adjust register, content or volume to listener and setting (playground versus adult, familiar versus stranger).
- Narrative and inference — trouble following the unwritten rules of conversation, reading implied meaning, idiom or non-literal language.
- Non-verbal integration — mismatch between gesture, eye gaze, facial affect and speech.
Differentiate from ASD (no restricted/repetitive patterns), from primary structural language disorder, and from hearing impairment or global developmental delay. Symptoms must exceed expectations for developmental level and impair functioning across settings.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an app or checklist. Our profiling separates pragmatic from structural language to target intervention precisely. See Social Communication Difficulties, speech therapy, and the AbilityScore®.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Pragmatic difficulty disproportionate to intact grammar and vocabulary — poor turn-taking, failure to adapt to listener, literal interpretation, and gesture–speech mismatch, persisting across settings without restricted/repetitive behaviours.
In everyday life
When structural language tests look normal but conversation breaks down, probe pragmatics directly — narrative retell, inference and turn-taking sampling reveal what standardised vocabulary measures miss.

Bring your questions to a first visitQuestions families ask
How does 6A01.22 differ from autism spectrum disorder?
Both involve social-communication impairment, but Social Communication Difficulties is diagnosed only when the restricted, repetitive behaviours and interests required for ASD are absent. If those features are present, an ASD diagnosis takes precedence.
At what age can it be reliably identified?
Pragmatic difficulties become clearer once a child has enough language to demonstrate conversational use — typically from the preschool years onward — and must be disproportionate to developmental level and persistent across settings before diagnosis.
Does intact grammar rule out a communication disorder?
No. A child may have age-appropriate vocabulary and syntax yet struggle with the social use of language. Pragmatic assessment is needed because structural language measures alone can miss the difficulty.
