Cross-Cultural Differences in the Interpretation of Autistic Traits: A Comparison Between Iran, Malaysia, Morocco,...

The diagnosis of Autism relies partly on the evaluation of social behavior. What is perceived as "appropriate" (social) behavior is influenced by culture, as culture shapes norms and beliefs about behavior. Culture might thus influence the interpretation of autistic traits and the diagnostic process. We aimed to study whether culture affects the interpretation and reporting of autistic traits and how autism knowledge is associated with these relations.

To do so, we investigated cross-cultural differences in self-reported autistic traits (autism-spectrum Quotient) and the commonness of these traits in Iran (n = 88), Malaysia (n = 181), Morocco (n = 94), and the Netherlands (n = 113). Additionally, we explored the relationship between (the commonness of) autistic traits and autism knowledge (Revised Autism Knowledge Survey) across these countries.

The results indicated, consistent with previous studies, cross-cultural differences in both self-reported autistic traits and the commonness of these traits. Cross-cultural differences in reporting autistic traits showed that cultural background might affect their interpretation. There was a relationship between self-reported and the commonness of autistic traits. When autistic traits are considered more common, people also self-report more traits. In addition, more knowledge about autism was related to lower self-reported traits. However, within individual countries, the relationships were more nuanced.

It is, hence, essential to consider cultural background and autism knowledge when assessing autism cross-culturally.
