The goal of this study was to examine the cross-cultural validity and reliabilityof the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) – arecently published instrument for assessing the Zuckerman’sAlternative Five Factor Personality Model – in Catalan and Hungarianspeaking populations. The samples consisted of 1,564 subjects from Catalonia and1,647 from Hungary. Results showed a clear five-factor structure and acceptablealpha reliabilities of the ZKA-PQ in both countries. Facets alpha average was80.35 and 74.10 for Catalans and Hungarians respectively. The factorialcongruency coefficients indicated that both structures were equivalent, with aglobal value of .97. However, the robust structure obtained with EFA yieldedpoor fit indices in the subsequent CFA. Altogether, the psychometric findingswere similar to those obtained in the original validation study carried out inSpanish and English populations. Main country differences were found only inNeuroticism 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 mediumeffect size [F(1, 3188) = 292, p< .001, η2 = .0841].
