Structural analysis of the facets and domains of the Zuckerman–Kuhlman–Aluja personality questionnaire (ZKA–PQ) and the NEO PI–R. Journal of Personality Assessment, 94(2), 156-163.http://hdl.handle.net/11268/340Aluja, Kuhlman, and Zuckerman (2010) developed an instrument for American and Spanish populations (Zuckerman-Kuhlman-Aluja Personality Questionnaire [ZKA-PQ]) that includes 4 facets for each 5 basic traits of Zuckerman's psychobiological personality model. This new instrument is intended to improve the previous measure based on the same personality model, the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), by including the narrower traits (facets) defining the factors. This article explores the convergent and discriminant validity of the new instrument relative to the NEO PI-R in a sample from the Spanish general population. A series of exploratory factor analyses comparing both instruments was conducted. Results showed good convergent and discriminant validity between both instruments, although the ZKA-PQ had a slightly better structure than the NEO PI-R. The results support the validity of the ZKA-PQ factor domains and the facets composing them. The new instrument might be useful in both applied and research settings.engjournal article10.1080/00223891.2011.645935restricted accessPsicología
