The aim of this weekly diary study was (a) to identify trajectories of workplace bullying over time and (b) to examine the association of each cluster with strain indicators (i.e., insomnia and anxiety/depression). A sample of 286 employees during 4 weeks of data was used (N occasions = 1,144). Results of latent class growth modeling showed that 3 trajectories could be identified: a nonbullying trajectory, which comprised 90.9% of the sample; an inverted U trajectory; and a delayed increase bullying trajectory; the latter two each had 4.2% of the participants. We found a significant interaction between time and trajectories when predicting insomnia and anxiety/depression, with each strain showing a differential pattern with each trajectory. It seems that the negative effects on insomnia are long-lasting and remain after bullying has already decreased. In the case of anxiety and depression, when bullying decreases strain indicators also decrease. In this study, by examining trajectories of bullying at work over time and their associations with strain, we provide new insights into the temporal dynamics of workplace bullying.

工作场所欺凌的短期轨迹及其对压力的影响：潜在阶级增长建模方法。

这项每周日记研究的目的是 (a) 确定工作场所欺凌随时间推移的轨迹和 (b) 检查每个集群与压力指标（即失眠和焦虑/抑郁）的关联。在 4 周的数据中使用了 286 名员工的样本（N 次 = 1,144）。潜在类别增长模型的结果表明，可以确定 3 条轨迹：非欺凌轨迹，占样本的 90.9%；倒U形轨迹；以及延迟增加的欺凌轨迹；后两者各占 4.2%。在预测失眠和焦虑/抑郁时，我们发现时间和轨迹之间存在显着的相互作用，每种菌株在每个轨迹上都显示出不同的模式。似乎对失眠的负面影响是持久的，并且在欺凌已经减少后仍然存在。在焦虑和抑郁的情况下，当欺凌减少时，压力指标也会减少。在这项研究中，通过检查工作中欺凌随时间推移的轨迹及其与压力的关联，我们为工作场所欺凌的时间动态提供了新的见解。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
