What Is the ICD‑11 Criteria for Autism?
The ICD‑11 autism criteria provide the official diagnostic framework for identifying autism spectrum disorder, as outlined by the World Health Organization. This updated WHO classification aligns closely with modern clinical understanding, focusing on key behavioural features and support needs rather than outdated labels.
Key ICD‑11 Autism Criteria
Diagnosis using the ICD‑11 autism criteria involves identifying features across specific symptom domains, rather than relying on a fixed list of checkboxes. Here’s what professionals assess:
Deficits in social interaction and communication
These may include difficulties with social reciprocity, maintaining conversations, understanding social cues, or forming peer relationships.
Restricted and repetitive patterns of behaviour
This includes behaviours such as repetitive movements, strong insistence on routines, intense or unusual interests, and hypersensitivity or reduced sensitivity to sensory input.
Onset during the developmental period
Symptoms must begin in early childhood, even if they only become fully evident later due to social or environmental demands.
Functional impairment
The features must cause meaningful difficulties in daily functioning, such as in education, work, or relationships.
Unlike earlier models, ICD‑11 adds qualifiers for intellectual and language development, enabling a more nuanced diagnosis that captures the individual’s abilities and support needs.
Why the Criteria Matter
The ICD‑11 autism criteria aim to create a consistent and inclusive diagnostic experience across global health systems. These criteria list not only reflects real-world autism presentations but also guides service planning and research worldwide.
