Psychometric Properties of the HEXACO-100

Abstract

Psychometric properties of the 100-item English-language HEXACO Personality Inventory–Revised (HEXACO-PI-R) were examined using samples of online respondents ( N = 100,318 self-reports) and of undergraduate students ( N = 2,868 self- and observer reports). The results were as follows: First, the hierarchical structure of the HEXACO-100 was clearly supported in two principal components analyses: each of the six factors was defined by its constituent facets and each of the 25 facets was defined by its constituent items. Second, the HEXACO-100 factor scales showed fairly low intercorrelations, with only one pair of scales (Honesty–Humility and Agreeableness) having an absolute correlation above .20 in self-report data. Third, the factor and facet scales showed strong self/observer convergent correlations, which far exceeded the self/observer discriminant correlations.
