The present study examines the lack of strong correlations among existing self-report measures of narcissism. A principal-components analysis of 6 MMPI narcissism scales resulted in 2 orthogonal factors, 1 implying Vulnerability-Sensitivity and the other Grandiosity-Exhibitionism. Although unrelated to each other, these 2 factors were associated with such core features of narcissism as conceit, self-indulgence, and disregard of others. Despite this common core, however, Vulnerability-Sensitivity was associated with introversion, defensiveness, anxiety, and vulnerability to life's traumas, whereas Grandiosity-Exhibitionism was related to extraversion, self-assurance, exhibitionism, and aggression. Three alternative interpretations of these results are considered, and an argument for the distinction between covert and overt narcissism is made.
