title: Development of a brief version of the Pathological Narcissism Inventory.
abstract: With theoretical and empirical interest in narcissism growing, there is a need for brief measures of pathological narcissism that can be used more practically while assessing the construct comprehensively. Data from four samples (total N = 3,851) collected across two separate research groups and representing undergraduate, community, and clinical populations were used to establish the reliability, validity, and utility of the Brief-Pathological Narcissism Inventory (B-PNI). Item response theory and confirmatory factor analyses were used to determine the best-performing 28 items from the original PNI and ensure that the B-PNI exhibited a factor structure consistent with the original PNI. Items were retained for all seven pathological narcissism facet scales. Additional results also support the criterion validity of the B-PNI, suggesting that it can be used in place of the original PNI to assess the various facets of pathological narcissism effectively and without loss of information, which may enhance the ability of researchers to investigate pathological narcissism in future work.
