Individual differences in narcissism: Inflated self-views across the lifespan and around the world

Reactions to trait self-enhancers were investigated in 2 longitudinal studies of person perception in discussion groups. Groups of 4-6 participants met 7 times for 20 min. After Meetings 1 and 7, group members rated their perceptions of one another. In Study 1, trait self-enhancement was indexed by measures of narcissism and self-deceptive enhancement. At the first meeting, self-enhancers made positive impressions. They were seen as agreeable, well adjusted, and competent. After 7 weeks, however, they were rated negatively and gave self-evaluations discrepant with peer evaluations they received. In Study 2, an independent sample of observers (close acquaintances) enabled a pretest index of discrepancy self-enhancement: It predicted the same deteriorating pattern of interpersonal perceptions as the other three trait measures. Nonetheless, all self-enhancement measures correlated positively with self-esteem.

Three studies are reported which provide evidence for the validity of the Narcissistic Personality Inventory (NPI). Factor analysis of the NPI in Study 1 revealed four factors which were labelled: Exploitativeness/Entitlement, Leadership/Authority, Superiority/Arrogance, and Self-absorption/Self-admiration. In Study 2, scores on the NPI were correlated with basic dimensions of personality, and with relevant self-variables. Narcissism scores were positively related to dominance, exhibitionism, extraversion, self-esteem, and self-monitoring, among others; and negatively related to abasement, deference, and social anxiety, among others. Correlations between the NPI factors and personality variables are also examined. In Study 3, peer ratings of narcissism were obtained and it was found that these were strongly related to scores on the NPI. Taken together, the three studies provide considerable evidence for the construct validity of the NPI, and avenues for future research are suggested.
