401 men and 475 women completed the Dutch version of the Eysenck Personality Questionnaire. Factor comparisons all exceeded 0.97 so that the factors of Psychoticism, Extraversion, Neuroticism, and Social Desirability are deemed to be identical in the two countries, England and The Netherlands. Sex differences conform with those in most other cross-cultural studies, namely, men score higher than women on Psychoticism and Extraversion, but lower on Neuroticism and Social Desirability. Reliabilities (alpha coefficients) are satisfactorily high for all factors, although the lowest value (0.62) for the Psychoticism dimension for Dutch men appears somewhat weak. National differences on personality variables were only significant for the Neuroticism scale and Social Desirability; Dutch men and women scored lower on the Neuroticism scale than their English counterparts but higher on Social Desirability.
