The association between victims' vulnerable and grandiose narcissism and grudge holding

Two nonexperimental studies were conducted to test how and why transgression victims' narcissism influences their grudge holding, using undergraduate students and a community sample of adults, respectively. Study 1 tested the association between victims' vulnerable narcissism and grudge holding, including emotional persistence, perceived longevity, and disdain toward the transgressor. It also tested the extent to which victims' grandiose narcissism moderated the association. Study 2 was conducted to replicate Study 1 and test whether victims' rumination about the transgression mediated the moderated association. Overall, those with higher degrees of grandiosity showed a positive relation between vulnerable narcissism and reported emotional persistence (Studies 1 and 2) and perceived longevity (Study 2). Finally, rumination explained the moderated relation (Study 2).
