History
From HEXACO-PI to HEXACO-PI-R
Construction of the HEXACO Personality Inventory began in 2000. The aim was to assess the six personality dimensions found in lexical studies across languages, and to reflect Ashton & Lee’s theoretical interpretations of those factors. By 2002, a provisional 108-item version was in use — six scales of 18 items each, without separate facet subscales.
The HEXACO Personality Inventory-Revised (HEXACO-PI-R) introduced two key changes. Within Extraversion, the Expressiveness facet was replaced by Social Self-Esteem. The interstitial Negative Self-Evaluation scale was removed. The PI-R now assesses four facets within each of the six factors, plus the interstitial Altruism scale — 200 items in the full HEXACO-200, or 100 items in the half-length HEXACO-100.
When computing the six factor scores, Altruism items are not included. If factor scores are computed as principal components, the Altruism scale can be included with the other 24 facets — it generally divides its loadings between Honesty-Humility, Emotionality, and Agreeableness.

Domain and facet scores are typically reported on a 1–10 scale (higher = more of that trait). The bell curves below show where a score sits relative to the general population distribution. Percentile bands (<10th, 10–50th, 50–90th, >90th) are marked along the horizontal axis.
