Individuals higher in grandiose narcissism strive to create and maintain their inflated self-views through self-aggrandizing and other-derogating behaviors. Drawing from the dual-process model of narcissistic admiration and rivalry, we proposed that individuals higher in narcissism may contribute to more competitive and less cooperative conflict processes. We tracked over 100 project design teams from inception to dissolution, gathering data at three time points. We evaluated how team levels of narcissism (i.e., maximum team score, team mean, and team variance) related to latent team means of cooperative and competitive conflict processes. Team mean scores of narcissistic rivalry corresponded to less cooperative and more competitive team conflict processes as teams approached their final project deadline. Our results show how narcissistic rivalry (but not admiration) alters the types of team conflict processes that arise within groups, and is particularly consequential as teams approach major project deadlines.

自恋自大的人通过自我强化和其他贬损行为来努力创造和维持自己夸张的自我观。从自恋和自恋的双重过程模型中，我们提出自恋程度较高的个人可能会促进更具竞争性和合作性的冲突过程。从成立到解散，我们跟踪了100多个项目设计团队，并在三个时间点收集了数据。我们评估了团队自恋的水平（即，最大团队得分，团队平均数和团队差异）与潜在的团队合作和竞争性冲突过程的方式如何相关。当团队接近最终项目截止日期时，自恋竞争的团队平均分数对应于合作性较低，团队竞争更具竞争性的过程。
