Up until now, no really short instrument that measures the six personality dimensions of the HEXACO model has been available. In two studies, I report the construction of the Brief HEXACO Inventory (BHI), which represents the 24 HEXACO facets with 1 item per facet (i.e., 4 items per domain) and which takes approximately 2-3. min to complete. Although characterized by relatively low alpha reliability, its test-retest stability, self-other agreement, and convergent correlations with full-length scales are relatively high and its validity loss is only modest. Correcting for attenuation using a weighted average of alpha reliability, test-retest stability, and self-other agreement, the BHI re-estimates the original construct validity correlations of the HEXACO-PI-R with relatively great accuracy. © 2013 Elsevier Inc.
