Psychometric analysis of two versions of the Big Five Inventory-15 in Chilean college students: internal structure, measurement invariance and association with subjective well-being

The purpose of this research was to analyze the internal structure of the Big Five Inventory-15 (BFI-15), measurement invariance and its association with subjective well-being, in Chilean college students. A sample of 1011 college students (female = 54.80%; Mage = 21.55 years; SDage = 2.11 years) was used. Results showed the Peruvian version of BFI-15 (BFI-15p) has more consistent indicators regarding their internal structure (e.g., factor loadings) compared to the German (BFI-15a) version, an invariant structure between men and women, and a significant association with subjective well-being was found. Finally, the construct reliability and scores reliability reached adequate magnitudes. It is concluded that the BFI-15p has adequate psychometric properties for use in Chilean college students.
