This study examines the predictive value of conflict and conflict-related variations in negative emotion dynamics, with respect to three cortisol indicators (cortisol awakening responses; overall cortisol output; diurnal cortisol slopes). A total of 166 workers provided momentary reports on conflict(s) with colleagues and negative emotions 10 times a day for 2 workdays and salivary cortisol samples 5 times a day. The results of latent growth curve piecewise multilevel models revealed that the occurrence of a conflict and the number of conflicts introduced significant variations in specific cortisol parameters indicating greater cortisol levels throughout the day. Moreover, the conflict-elicited negative emotion boost predicted a lower reduction of cortisol levels from morning to evening. Last, the postconflict decline in negative emotions was negatively associated with overall cortisol production. This study contributes to establishing a potential association between naturally occurring episodic conflicts at work and daily cortisol patterns, identifying within-person fluctuations in negative emotions as psychological mechanisms through which this occurs.

工作中关系冲突的动态关联以及随之而来的负面情绪动态与昼夜皮质醇变化的关系。

本研究针对三个皮质醇指标（皮质醇觉醒反应；总体皮质醇输出；昼间皮质醇斜率），考察了负面情绪动态中冲突和冲突相关变化的预测价值。共有 166 名员工在 2 个工作日内每天提供 10 次与同事冲突和负面情绪的即时报告，并每天提供 5 次唾液皮质醇样本。潜在增长曲线分段多级模型的结果表明，冲突的发生和冲突的数量会导致特定皮质醇参数的显着变化，表明全天皮质醇水平较高。此外，冲突引发的负面情绪增加预示着从早上到晚上皮质醇水平的下降幅度较小。最后，冲突后负面情绪的下降与整体皮质醇的产生呈负相关。这项研究有助于建立工作中自然发生的偶发冲突与日常皮质醇模式之间的潜在关联，并将人体内负面情绪的波动识别为发生这种情况的心理机制。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
