People increasingly support themselves through multiple jobholding-concurrently performing more than one job-and spend time enacting their professional identities each day. In accordance with self-consistency theory, scholars have emphasized that having to act out more than one professional identity promotes a fragmented sense of self for multiple jobholders, which impedes the meaningfulness of their work. However, we assert that this prevailing view about self-inconsistency is incomplete and problematic because it overlooks consideration for how enacting multiple professional identities may be a self-expanding and stimulating experience that satisfies basic needs for growth and exploration. By jointly applying self-expansion theory and self-consistency theory to the day-to-day experience of wearing multiple hats, we unpack how and why enacting multiple professional identities has countervailing implications for work meaningfulness through its effects on stimulation and self-alienation. We also consider the moderating role of identity contrast on these pathways to meaningfulness. We investigate our assertions in a series of preregistered studies-a comprehensive test of our model in a 15-day experience sampling study (Study 1) as well as constructive replications of each stage of our model (Study 2). Overall, we offer novel insights about the day-to-day tension between stimulation and self-alienation for people who act out multiple professional identities and the impact on the meaningfulness of their work.

身兼数职导致自我矛盾或自我膨胀？制定多重职业身份对工作意义的日常影响。


人们越来越多地通过从事多种工作（同时从事一项以上的工作）来养活自己，并每天花时间展现自己的职业身份。根据自我一致性理论，学者们强调，必须表现出多种职业身份会导致多个工作人员的自我意识支离破碎，从而阻碍了他们工作的意义。然而，我们断言，这种关于自我不一致的普遍观点是不完整的，也是有问题的，因为它忽视了对多重职业身份如何成为一种自我扩展和刺激的体验的考虑，从而满足成长和探索的基本需求。通过将自我扩展理论和自我一致性理论联合应用于身兼数职的日常体验，我们揭示了制定多重职业身份如何以及为何通过其对刺激和自我异化的影响而对工作意义产生反作用。我们还考虑了身份对比对这些通往意义的途径的调节作用。我们在一系列预先注册的研究中调查了我们的主张——在 15 天的经验抽样研究中对我们的模型进行了全面测试（研究 1），以及对我们模型的每个阶段进行建设性复制（研究 2）。总体而言，我们针对具有多重职业身份的人们的日常刺激与自我疏离之间的紧张关系以及对其工作意义的影响提供了新颖的见解。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
