STRUCTURAL ANALYSIS AND MEASUREMENT INVARIANCE REGARDING THE SEX OF THREE BRIEF VERSIONS OF THE BIG FIVE INVENTORY IN MEXICAN GENERAL POPULATION

Abstract

Assessing personality with short scales is becoming relevant in different fields of psychology. Therefore, the purpose of this study is to analyze the internal structure and reliability of three short versions of the Big Five Inventory in a sample of 500 Mexican citizens (60.8% men; Mage = 23.58). The German (BFI-15; 15 items), Peruvian (BFI-15p; 15 items), and Brazilian (BFI-20; 20 items) versions were analyzed using exploratory structural equation modeling. The Peruvian version (BFI-15p) showed a simpler factorial structure and factor loadings with acceptable magnitudes, as well as adequate reliability coefficients. Likewise, the BFI-15p was invariant between men and women, with women scoring greater Agreeableness, Neuroticism, and Openness than men. The implications of these findings and recommendations for future studies are discussed. © 2024 Elsevier B.V., All rights reserved.
