This study examined the subdimensional structure of the Hogan Personality Inventory (HPI). A sample of 200 Spanish applicants completed the HPI as a requirement of a selection process for several jobs at a large international company. Exploratory factor analyses were conducted with the homogenous item composites (HIC) included in the HPI. Globally, the results indicated that the Big Five are divided into 13 subdimensions, which explained the variance of the HICs. Based on these results, we suggest that the HPI can be described as a personality inventory consisting of a hierarchical structure of three levels (Big Five – subdimensions – HICs).
