| Abstract: | The Narcissistic Personality Inventory (NPI) is the primary measure of grandiose narcissism (GN) despite possessing numerous limitations. Here we present a new 33-item measure of GN called the Grandiose Narcissism Scale (GNS) that exhibits a reproducible seven-factor structure that maps on to Raskin and Terry’s (1988) seven factor model. GNS subscales exhibit high reliability, with several being substantially more reliable than their NPI counterparts. As a full-scale, the GNS correlates with other variables in a way that is consistent with the theoretical portrait of GN. Additionally, two of the GNS subscales (entitlement, exploitativeness) are shown to uniquely predict independent measures of entitlement and exploitativeness, suggesting good subscale validity. Cumulatively, the GNS represents a viable complement or alternative to the NPI. |
