The present study was to explore the relationship between personality traits correlate to narcissism and self-esteem.In an attempt to understand why the individualist behaviour can influence the sportive competition outcomes.　　The relation between personality traits and sport teams results are unclear despite numerous attempts to illuminate these links.We put the self-identity (SE/NPI) in historical context and review the existing empirical evidence.We then discuss the possible issues that might shed light on the inconsistent findings that have emerged.These include the limitations of implicit attitudes measures, the possibility that narcissists negative underlying self-views pertain primarily to their communal qualities, and the.existence of distinct subtypes of narcissism that relate differently to self-esteem.　　We discussed two alternative approaches to the study of narcissism that reflect different conceptualizations of the distinction between self and performance.The rate of winning acted as criterion in the regression analysis, and the self-esteem and NPI entered the regression as predictors.Due to many differences of sports ecology between genders, gender may moderate the impact of NPI and self-esteem on team performance.However, given the complexities of three-way interaction in regression analysis, we conducted only two moderation analysis, analyzing on moderation at a time.　　The results suggest that the more narcissistic a male player is, the lower the rate of winning of his team will be (about 2％ drop in winning rate for every point increase in NPI).The trend for female is reversed; the increase in narcissism would boost team performances during a competitive season.　　For self-esteem the result suggests that increasing in male players of a sport team would lead to slightly lower rate of winning (about 1％ for every point increased in self-esteem) during a whole season.Conversely, for female players, increasing self-esteem would lead to greater overall performance during a competitive season.　　Meanwhile, we offer suggestions to improve the study of narcissism and self-esteem then its impacts on the group performance achievement and might therefore explore more thoroughly the domain upon which narcissists are likely to base their self-esteem in order that point to directions for the future research.
