Convergence and Divergence of Grandiose and Vulnerable Narcissism with the Minnesota Multiphasic Personality Inventory-2-Restructured Form

In clinical and empirical literature, there are many different conceptualizations of the construct of narcissism, but most will agree that narcissism includes at least two broad dimensions: grandiosity and vulnerability. The aim of this study was to corroborate both grandiose and vulnerable narcissism constructs by extending the nomologic net of both dimensions. We therefore investigated the convergences and divergences of the Pathological Narcissism Inventory (PNI) dimensions with the Personality Psychopathology Five-revised (PSY-5-r) trait domains and other Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scales in a community sample (N= 251). Results showed that there is clear and conceptually logical convergence between the PNI scales and MMPI-2-RF PSY-5-r trait domains and other MMPI-2-RF scales. Also, the narcissism factors diverge like expected in terms of associations with MMPI-2-RF scales capturing internalizing aspects. Internalizing MMPI-2-RF scales showed positive relations with vulnerability and negative relations with grandiosity. Moreover, grandiosity did relate positively MMPI-2-RF externalizing scale.
