The Zuckerman-Kuhlman Personality Questionnaire, a tool designed to measure the alternative five-factor model of personality, was translated and adapted into the Spanish language. Some psychometric results with students have already been reported, but to date, there appears to be no published data on the psychometric properties of the questionnaire in a general population sample in any culture. The aim of the present study was to provide psychometric properties for a large Spanish community sample with a wide representation of adult age-range, a representative distribution of sexes, and a balanced distribution of education within the sample. Participants volunteered and were selected on a random basis. The questionnaire was administered to 1,000 participants of both sexes (51.4% women) with ages ranging from 18 to 88 years (M = 45.4, SD= 18.7). Analysis gave a normal distribution of all scales, good internal consistencies, and discriminant validity. Sex differences were in accord with data from tests measuring similar personality traits. Finally, the original five-component structure was also replicated. © Psychological Reports 2008.
