The goal of this study was to examine the cross-cultural validity and reliability of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) – a recently published instrument for assessing the Zuckerman’s Alternative Five Factor Personality Model – in Catalan and Hungarian speaking populations. The samples consisted of 1,564 subjects from Catalonia and 1,647 from Hungary. Results showed a clear five-factor structure and acceptable alpha reliabilities of the ZKA-PQ in both countries. Facets alpha average was 80.35 and 74.10 for Catalans and Hungarians respectively. The factorial congruency coefficients indicated that both structures were equivalent, with a global value of .97. However, the robust structure obtained with EFA yielded poor fit indices in the subsequent CFA. Altogether, the psychometric findings were similar to those obtained in the original validation study carried out in Spanish and English populations. Main country differences were found only in Neuroticism factor, with Hungarians scoring significantly lower that Catalans. Nevertheless, country, sex and age explained only 18.6 % of Neuroticism variance (adjusted R squared = .186). Country differences had only medium effect size [F(1, 3188) = 292, p < .001, η2 = .0841].
