Conventionally, identity centrality has been conceived of as a stable and transsituational construct, with situational variability in identity centrality treated as being of little informational value. In contrast to past research, we develop a theoretical model arguing that a portion of within-person variability in identity centrality is systematic and meaningful. Drawing on identity control theory, we examine the within-person relationship flowing from perceived role progress to state identity centrality, which is conventionally viewed as reverse causal at the between-person level. We further explain the intermittent effect of an intense positive emotion-passion for the role-and investigate the contingent effect of in-role effort. The results from 2 repeated-measures studies showed that a significant proportion of total variance in identity centrality occurred at the within-person level and perceived role progress influenced state identity centrality by engendering passion for the role contingent on in-role effort. We discuss the theoretical and practical implications of our findings for management and organizations to inspire new intellectual debate and novel viewpoints to advance the microfoundation of identity theory.

身份中心性的个体内变异性：检查感知角色进展和国家身份中心性的动态。

传统上，身份中心性被认为是一种稳定的、转换性的结构，身份中心性的情境可变性被视为几乎没有信息价值。与过去的研究相比，我们开发了一个理论模型，认为身份中心性的一部分人内可变性是系统的和有意义的。借鉴身份控制理论，我们研究了从感知角色进展到状态身份中心的人内关系，这通常被视为人与人之间的反向因果关系。我们进一步解释了强烈的积极情绪——对角色的热情——的间歇性效应——并调查了角色努力的偶然效应。2 项重复测量研究的结果表明，身份中心性的总方差中有很大一部分发生在个人层面，并且感知到的角色进步通过产生对角色的热情取决于角色内的努力来影响国家身份中心性。我们讨论了我们的发现对管理和组织的理论和实践意义，以激发新的知识辩论和新颖的观点，以推进身份理论的微观基础。（PsycINFO 数据库记录 (c) 2019 APA，保留所有权利）。我们讨论了我们的发现对管理和组织的理论和实践意义，以激发新的知识辩论和新颖的观点，以推进身份理论的微观基础。（PsycINFO 数据库记录 (c) 2019 APA，保留所有权利）。我们讨论了我们的发现对管理和组织的理论和实践意义，以激发新的知识辩论和新颖的观点，以推进身份理论的微观基础。（PsycINFO 数据库记录 (c) 2019 APA，保留所有权利）。
