What is the effect of trait narcissism on creative performance? Although both constructs share an emphasis on uniqueness and novelty, prior investigations of the narcissism–creative performance relationship have produced inconsistent findings and failed to provide conclusive answers to this question. One possible reason for the seemingly contradictory evidence is that extant research has examined the influences of leader and follower narcissism separately rather than simultaneously. In this study, we address this issue by investigating leader–follower narcissism (in)congruence to comprehensively understand when and why leader or follower narcissism is beneficial or detrimental to creative performance. Integrating the self-orientation model of narcissism and narcissistic-tolerance theory, we posit that leader and follower narcissism jointly influence creative performance via identification with the leader, and that different leader–follower narcissism (in)congruence combinations exhibit distinct effects. The analyses of two-wave, two-level, and multi-source data from 421 followers and 54 direct leaders, using cross-level polynomial regressions, support our hypotheses: (1) identification with the leader is maximized when leader narcissism and follower narcissism are congruent; (2) identification with the leader is minimized when leader narcissism is higher than follower narcissism; and (3) identification with the leader mediates the effects of leader–follower narcissism (in)congruence combinations on creative performance.

自恋对创造性表现的矛盾影响：领导者-追随者自恋的作用以及追随者对领导者的认同


特质自恋对创造性表现有何影响？尽管这两种结构都强调独特性和新颖性，但之前对自恋与创造性绩效关系的研究得出了不一致的结果，并且未能为这个问题提供结论性的答案。看似矛盾的证据的一个可能原因是，现有的研究是分别而不是同时研究领导者和追随者自恋的影响。在本研究中，我们通过调查领导者-追随者自恋（不）一致性来解决这个问题，以全面了解领导者或追随者自恋何时以及为何对创造性表现有利或有害。整合自恋的自我定向模型和自恋容忍理论，我们假设领导者和追随者自恋通过对领导者的认同共同影响创造性绩效，并且不同的领导者-追随者自恋（不）一致性组合表现出不同的效果。使用跨级别多项式回归对 421 名追随者和 54 名直接领导者的两波、两层次、多源数据进行分析，支持我们的假设：（1）当领导者自恋和追随者自恋时，对领导者的认同最大化是一致的； （2）当领导者自恋高于追随者自恋时，对领导者的认同感会被最小化； (3)对领导者的认同介导了领导者-追随者自恋一致性组合对创造性绩效的影响。
