The HPI contains seven primary scales and six occupational scales.
The HPI contains 206 items that are keyed true and false. The items have been carefully reviewed for invasive or intrusive content and to ensure the inventory has no adverse impact on race/ethnicity or gender. The total completion time is 15 - 20 minutes with a 5th grade reading level.
The HPI was developed in the context of socio-analytic theory. Within this context, getting along with and getting ahead of others become dominant themes in social life. The seven scales of the HPI capture key behavioural tendencies relevant to these life themes. The scales are based on the Five-Factor Model of personality, but have been extended to create more robust measures of two factors: Surgency (Ambition and Sociability scales) and Openness (Inquisitive and Learning Approach scales).
Norms are available by group in sizes ranging up to 30,000 cases, and over 1,000,000 job applicants have been tested with the HPI. Data are available for virtually every major industry and job category in the economy.
HPI scores are stable over time test; retest reliabilities ranging from .74 to .86. The HPI has been used in over 400 validity studies and it successfully predicts occupational success in all major job categories. The HPI research archives date back to the mid 1970's and it continues to be one of the most widely accepted and used inventories for research on personality.
