Empirical interest in narcissism in the fields of psychology and social sciences has been growing in recent years, with scholars increasingly acknowledging that grandiose narcissism is best understood as a two-dimensional construct: rivalry (self-protec tion) and admiration (assertive self-enhancement). Despite the increase of utilizing the Narcissistic Admiration and Rivalry Questionnaires (NARQ), validating the NARQ across countries and language has not been extensively utilized. In the present study (n= 600), we sought to validate the Korean version of NARQ by investigating its theoretically derived relationship with the Narcissistic Personality Inventory (NPI), Big Five personality traits, self-esteem and envy (benign and malicious). The re sults supported the findings that the Korean version of NARQ is a reliable and valid measure of the two-dimensional struc ture of grandiose narcissism. Interestingly, we observed that the two-dimensional latent factors did not correlate with each other, indicating that admiration and rivalry can be distinct among Koreans. The findings broaden our understanding of the dynamics of narcissism by providing validated evidence of the NARQ in South Korea.
