We investigated measurement non-invariance of DSM-IV narcissistic personality disorder (NPD) criteria across age and sex in a population-based cohort sample of 2794 Norwegian twins. Age had a statistically significant effect on the factor mean for NPD. Sex had a statistically significant effect on the factor mean and variance. Controlling for these factor level effects, item-level analysis indi...

Narcissism has been a perennial topic for psychoanalytic papers since Freud's 'On narcissism: An introduction' (1914). The understanding of this field has recently been greatly furthered by the analytical writings of Kernberg and Kohut despite, or perhaps because of, their glaring disagreements. Despite such theoretical advances, clinical theory has far outpaced clinical practice. This paper pr...

DESPITE THE EVOLVING AGREEMENT concerning the descriptive clinical characteristics of the narcissistic personality, widely divergent views have developed regarding its underlying meta psychological assumptions and its optimal technical approach within a psychoanalytic modality of treatment. Kohut's approach to these latter is very different from the one I outlined in an earlier paper (1970) , o...

The present research examined how narcissism is manifested on a social networking Web site (i.e., Facebook.com). Narcissistic personality self-reports were collected from social networking Web page owners. Then their Web pages were coded for both objective and subjective content features. Finally, strangers viewed the Web pages and rated their impression of the owner on agentic traits, communal...

Two experiments tested the hypothesis that narcissistic men as deWned by the NPI (Narcissistic Personality Inventory; Raskin & Hall, 1979) would self-handicap more than low-NPI individuals because it makes it easy to claim potentially undeserved credit for success. In both experiments, high and low narcissistic men received either response contingent or noncontingent success feedback on a test ...

Premorbid personality characteristics could have a pathoplastic effect on behavioral symptoms and personality changes related to neurodegenerative diseases. Patients with personality disorders, in particular of the dramatic cluster, may present functional frontolimbic abnormalities. May these neurobiological vulnerabilities linked to a premorbid personality disorder predispose or represent a ri...

Since its introduction into the psychological literature, narcissism has been conceptualized as an emotional disorder—a result of excessive pride and shame. Following Freud (1914/1957), Kernberg (1975) argued that the central psychological process underlying the disorder— identifi cation with an idealized ego—necessarily leads to pride. Kohut (1971) placed greater emphasis on shame, viewing it ...
