How Do Diagnostic Practices Differ Across Cultures? 

Author: Lucia Alvarez, MSc | Reviewed by: Dr. Rebecca Fernandez, MBBS

Diagnostic practices for autism can vary significantly across countries and cultures. While core autism criteria such as those outlined in DSM-5 or ICD-11 aim to provide a universal framework, how these are applied is shaped by cultural norms, available resources, and local attitudes towards neurodevelopmental conditions. This variation can influence whether autism is identified early, late, or even at all. 

Cultural Norms and Social Expectations 

Cultural differences shape what is considered typical behaviour. For example, in some cultures, minimal eye contact is a sign of respect rather than a social communication deficit, which could influence diagnostic outcomes. 

Awareness and Understanding of Autism 

In regions with low public awareness, traits of autism may be misunderstood or attributed to personality. For instance, a child’s repetitive behaviours might be seen as a harmless habit rather than part of a broader diagnostic practices framework. 

Access to Diagnostic Resources 

Not all countries have the same access to trained specialists or standardised assessment tools. In some rural areas, families may rely on basic screening checklists rather than formal autism criteria evaluations, leading to delayed or missed diagnosis.  

Language and Cultural Adaptation of Tools 

Assessment tools may need cultural adaptation to be relevant. For example, a social play task familiar in the UK may not resonate in rural Asia, so a culturally specific alternative would be used instead.
