The Empathy and Systemizing Quotient: The Psychometric Properties of the Dutch Version and a Review of the Cross-Cultural Stability.

Li et al. (2015) checked if the Dutch Empathy Quotient and Systemizing Quotient work the same way as the English originals. They gave both questionnaires to the adults, half with autism and half without.

They looked at internal consistency, test-retest scores, and factor structure. They also pooled earlier studies to see if EQ and SQ scores hold up across Western and Asian cultures.

The Dutch EQ and SQ showed strong reliability (α > .80) and the expected two-factor shape. People with autism scored lower on empathy and higher on systemizing, just like in English samples.

When they compared 15 countries, Western nations produced nearly identical score patterns. Asian samples deviated: lower average EQ and wider gender gaps, hinting that culture tweaks how people answer.

Milne et al. (2009) put the SQ to work. They showed that higher systemizing scores predict stronger visual illusions in neurotypical adults, giving the SQ real-world validity beyond paper answers.

Diz et al. (2011) link high autistic-trait scores (AQ) to attention gaps under heavy visual load. Together these papers build a bridge: validated trait measures forecast measurable perceptual differences.

Hatton et al. (1999) and Davis et al. (1994) did similar survey-validation work with Dutch ID populations. Their methods echo Y et al., strengthening confidence that careful translation plus factor checks is a proven recipe.

If you run social-skills or vocational groups for Dutch-speaking adults, you can trust the Dutch EQ/SQ to flag empathizing or systemizing strengths. Pair the scores with Elizabeth et al.'s illusion task for a quick, culture-free probe of local processing style. When scores look off, remember Y's cross-cultural data: Asian clients may self-rate empathy lower even when behavior looks typical, so interpret with cultural context in mind.
