Abstract

Abstract: Cross-cultural invariance of personality measurement provides important information regarding the universality of personality traits. With the recent release of historical data from 33 countries on the Eysenck Personality Questionnaire (EPQ) the opportunity arose to test the invariance of the three personality dimensions measured by the EPQ, together with the response set scale. Although the factor structure of the EPQ has been much studied in previous decades, there was a need to validate the previously reported four-factor structure using modern factor analytic techniques. As anticipated, both exploratory and confirmatory factor analysis provided unsatisfactory models, for different reasons. Instead, exploratory structural equation modeling provided confirmation of the hypothesized oblique, four-factor structure. Results of measurement invariance comparisons across countries, separately by gender, showed striking evidence of the generalizability of the four-factor structure in pairwise comparisons with the English sample as the reference group. In addition, there was evidence of failure of item invariance, for a varying subset of items, in all of the between-country comparisons. However, the pattern of partial measurement invariance does not preclude effective use of the EPQ as a research tool in diverse cultures. The results provide strong theoretical convergence, with other published studies, on the universality of the four-factor structure. Highlights: This study validated the four-factor structure of the Eysenck Personality Questionnaire (EPQ). Most previous factor-analyses of the EPQ used exploratory techniques. Exploratory structural equation modeling demonstrated good fit of the four-factor model. Partial measurement invariance was demonstrated across data from 33 countries. Results suggest that the EPQ is a valid measure of the four-factor structure in diverse cultures.
