About the methodology
The Narcissistic Personality Inventory NPI-40 is based on the clinical criteria of narcissistic personality disorder from the DSM-III. The test consists of 40 forced-choice pairs designed to assess narcissistic traits in the non-clinical population.
NPI-40 measures seven components of narcissism: Authority, Exhibitionism, Superiority, Entitlement, Exploitativeness, Self-Sufficiency, and Vanity. Factor analysis confirmed the validity of the seven-factor structure.
The instrument demonstrates high internal consistency (α = 0.83) and test-retest reliability. NPI-40 is used in over 3,000 studies worldwide to examine narcissism as a personality trait.
