Given the steady increase in new leadership models and approaches introduced to the field, we provide a systematic review on the topic of construct proliferation in the leadership style literature. Construct proliferation suggests that newly designed constructs are too similar to existing ones and, consequently, lack discriminant validity. In our review, we tackle the issue of construct proliferation from two perspectives. First, we present explanations and evidence indicating construct proliferation. Then, we take the opposing stance and provide arguments (as well as empirical evidence) against it. This comparison results in a discussion in which we provide cues for future leadership style research that builds on the realization that we need a more nuanced awareness of where construct proliferation exists and where it does not.

促进领导风格研究的扩散

鉴于引入该领域的新领导模式和方法的稳步增长，我们对领导风格文献中的构造扩散主题进行了系统的综述。构造泛滥表明新设计的构造与现有构造过于相似，因此缺乏可判别的有效性。在我们的审查中，我们从两个角度解决了构造扩散的问题。首先，我们提出解释和证据表明构建体增殖。然后，我们采取相反的立场，并提出反对的论据（以及经验证据）。这种比较导致了一个讨论，在讨论中我们为未来的领导风格研究提供了线索，而这一认识的基础是我们需要对构造扩散存在于何处和不存在扩散有更细致的认识。
