This study examined narcissistic self-esteem regulation based on the relationship between narcissism and contingency of self-worth among Japanese adolescents. The results of correlation analysis indicated that the grandiose facet of narcissism was positively related to emphasis on appearance, competition, and family support, and negatively related to approval from others. The hypersensitive facet of narcissism was positively related to all dimensions of contingency of self-worth except appearance. The results for grandiose narcissism generally support the (extended) agency model. The necessity of investigating cultural differences in future studies was discussed.
