Convergent validity of three brief six-factor measures of personality

The HEXACO Personality Inventory-Revised (HEXACO-PI-R) is widely used in personality research. Several brief inventories measuring broadly similar six-factor structures have recently emerged (e.g., the Mini-International Personality Item Pool (Mini-IPIP6; Milojev et al., 2013), the Brief HEXACO Inventory (BHI; De Vries, 2013), and the 24-Item Questionnaire Big Six scales (24-QB6; Thalmayer et al., 2011)). Using self- and observer reports collected from 202 undergraduate students, we evaluated the similarities and differences among these three brief inventories. The BHI, which was developed specifically to measure the HEXACO factors, showed a clearer one-to-one correspondence with the original HEXACO scales than did the scales of the other two inventories. The results further illustrate the constructs assessed by the three short inventories.
