Inventory Of Narcissistic Personality Inventory

Narcissistic Personality Inventory: The Measurement for Narcissism

In 1979, there was a lack of an appropriate instrument for measuring narcissism. (Emmons, 1984)

In the area of social psychological research, Raskin and Hall (1979) created the NPI or The Narcissistic Personality Inventory. It is a tool for the measurement of narcissism as a personality trait. In the DSM-III, based on the meaning of narcissistic personality disorder found, the NPI is not for verifying if a person has a Narcissistic Personality Disorder. Instead, it measures narcissism in its subclinical or normal forms.

Someone who gets the highest probable score on the inventory does not necessarily have the disorder. A lot of published and unpublished follow-up researches

The PNI (Pincus et al., 2009) is a 52-item self-report measure of both vulnerable and grandiose narcissism traits. The PNI contains four vulnerable narcissism subscales (i.e., Contingent Self-Esteem, Hiding the Self, Devaluing, and Entitlement Rage) and three grandiose narcissism subscales (i.e., Self-Sacrificing Self-Enhancement, Grandiose Fantasies, and Exploitativeness).

Narcissistic Grandiosity Scale (NGS). The NGS (Rosenthal, Hooley, & Steshenko, 2007) is a measure of grandiose narcissism, which requires participants to rate themselves on 16 adjectives such as “superior” and “omnipotent” on a 1 (not at all) to 7 (extremely) scale. Scores from the NGS are significantly correlated with other measures of grandiose narcissism and traits associated with narcissism such as agreeableness and extraversion (e.g., Miller, Price, & Campbell, 2012; Miller, Price, Gentile, et al., 2012).
Hypersensitive Narcissism Scale (HSNS). The HSNS is a 10-item self-report measure of narcissism that is vulnerable. (Hendin & Cheek, 1997)

Psychological Entitlement Scale (PES). The PES is a self-report with nine items to measure how or to what extent individuals believe that they are more deserving than others. Items are scored on a 1 to 7 scale from “strong disagreement” to 7 “strong agreement.” (Campbell, Bonacci, Shelton, Exline, & Bushman,
