The Norwegian HEXACO-PI-R: Psychometric properties and relationships with the Big Five Inventory

The HEXACO model of personality structure consists of six factors that have been repeatedly recovered in lexical studies across languages (Ashton, Lee, & Perugini et al., 2004; Lee & Ashton, 2008). The purpose of the present study was to examine the psychometric properties of the HEXACO-PI-R in a Norwegian sample. College students ( n = 484; 82% female; mean age: 24.98 years) answered the Norwegian HEXACO-PI-R and the Big Five Inventory (BFI). Alpha reliability for HEXACO-PI-R factor scales was acceptable, whereas reliability coefficients for the facet scales varied with a mean α = .63. A principal axis factor analysis with varimax rotation showed that seven meaningful latent factors could be extracted, but when six latent factors were requested, a factor loading pattern in accordance with the HEXACO model emerged. Relationships between the HEXACO factors and BFI supported the convergent validity of the inventory. The relativity independence of Honesty-Humility from the Big Fig factors was evident, with the Big Five predicting only 20% of the variance in Honesty-Humility. The results indicate that the Norwegian HEXACO-PI-R is adequate for measuring the six factors of personality but more research, preferably in heterogeneous samples, is needed to fully establish the psychometric properties of the inventory.»/>
