The Narcissistic Personality Inventory (NPI) is a widely used measure of narcissism. However, debates persist about its exact factor structure with researchers proposing solutions ranging from two to seven factors. The present research aimed to clarify the factor structure of the NPI and further illuminate its nomological network. Four studies provided support for a three-factor model consisting of the dimensions of Leadership/Authority, Grandiose Exhibitionism, and Entitlement/Exploitativeness…

An Integrative Analysis of the Narcissistic Personality Inventory and the Hypomanic Personality Scale: Implications for Construct Validity
TLDR
The results establish that some NPI and HPS subscales more clearly tap content specifically relevant to narcissism and mania, respectively, than others, and challenge the construct validity of the NPI Leadership/Authority and H PS Social Vitality subscales, which appear to assess overlapping assertiveness content that is largely adaptive in nature.
Psychometric Properties of the Narcissistic Personality Inventory
The Narcissistic Personality Inventory (NPI) is one of the most widely used measures of trait expressions of narcissism in social/personality psychology. This chapter provides an overview of the
What Does the Narcissistic Personality Inventory Measure Across the Total Score Continuum?
The Narcissistic Personality Inventory (NPI) is the most widely used measure of narcissism in the social-personality psychology literature. It contains 40 items that tap into a variety of traits that
Exploring the structure of narcissism: Toward an integrated solution.
TLDR
A three-factor model seems to be the most parsimonious conceptualization of narcissism, and larger factor solutions are discussed, but future research will be necessary to determine the value of these increasingly narrow factors.
Five-Factor Model Best Describes Narcissistic Personality Inventory Across Different Item Response Formats
TLDR
The results showed that the five-factor model proposed by Ackerman et al. had the best model fit in both response formats and that a distinction between adaptive (Leadership, Vanity, and Superiority) and some aspects of maladaptive (Manipulativeness and Exhibitionism) narcissism factors could be established.
French Adaptation of the Narcissistic Personality Inventory in a Belgian French-Speaking Sample
TLDR
A unidimensional structure for the NPI is supported using the total score as a self-report measure of the Narcissistic Personality Disorder in its grandiose form using a principal component analysis on a tetrachoric correlation matrix.
Psychometric Properties of a French Version of the Narcissistic Personality Inventory in Young Adults
The Narcissistic Personality Inventory (NPI) is widely used in social and personality psychology. The present study validates a French version of the NPI (NPI-Fr) for use with young adults.
Replicable Factor Structure and Correlates of an Alternate Version of the Narcissistic Personality Inventory
The Narcissistic Personality Inventory (NPI) traditionally has been administered using 40 pairs of items with a forced-choice response format. However, recent NPI research indicates that it may be

On the Meaning and Measure of Narcissism
TLDR
The studies show that measures of grandiosity and entitlement interact to predict scores on the NPI, controlling for gender, self-esteem, and basic personality, but also that grand Curiosity and entitlement function independently with respect to mental health and ethical misconduct.
Factor analysis and construct validity of the Narcissistic Personality Inventory.
TLDR
Three studies are reported which provide evidence for the validity of the Narcissistic Personality Inventory (NPI), and avenues for future research are suggested.
Narcissism: theory and measurement.
TLDR
The Exploitiveness/Entitlement subscale was found to correlate with measures of pathological narcissism and affective intensity and variability and the relevance of Linville's (1982) theory of self-complexity-affect intensity for understanding aspects of narcissism is outlined.
A principal-components analysis of the Narcissistic Personality Inventory and further evidence of its construct validity.
TLDR
Evidence is found for a general construct of narcissism as well as seven first-order components, identified as Authority, Exhibitionism, Superiority, Vanity, Exploitativeness, Entitlement, and Self-Sufficiency, in the Narcissistic Personality Inventory.
The Factor Structure of the Narcissistic Personality Inventory
TLDR
The 2-factor models for the NPI appeared to be the most parsimonious models, with both a good fit to the data and satisfactory internal consistency values; so they are recommended for use.

TLDR
Narcissistic Personality Inventory factors and a narcissistic Superiority Scale were similarly affected by partialing, appearing healthier when controlling for "maladaptive" narcissism and more unhealthy when removing the more " adaptive" variance.
