The relationship between posttraumatic stress disorder (PTSD) and anger is well established. However, further investigation into the underlying mechanisms of this PTSD-anger relationship is needed. Rumination, a construct with a known association to PTSD symptoms, theoretically may mediate this PTSD-anger relationship.
We conducted a mediational model using self-report measures of PTSD symptoms, rumination, and anger reactions from a nonclinical, trauma-exposed sample ( = 339) through Amazon's Mechanical Turk.
Rumination mediated overall PTSD symptoms and anger reactions, controlling for age and gender identity. Further analyses examined this mediating role between PTSD subscale scores and anger. Rumination mediated all PTSD subscales and anger when modeled separately. After adjusting for other PTSD symptoms, only 2 subscales' relationship with anger remained mediated by rumination: negative alterations in cognitions/mood and physiological arousal.
Rumination should be assessed in the context of PTSD and anger symptoms, specifically physiological arousal and negative moods/cognitions symptoms in PTSD. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
创伤后应激障碍（PTSD）与愤怒之间的关系已得到充分证实。然而，需要进一步研究这种 PTSD-愤怒关系的潜在机制。反刍，与 PTSD 症状有已知关联的一种结构，理论上可能在 PTSD-愤怒关系中起中介作用。
我们通过 Amazon 的 Mechanical Turk 使用非临床创伤暴露样本（n = 339）的自我报告 PTSD 症状、反刍和愤怒反应的测量来进行中介模型。
反刍在控制年龄和性别认同的情况下，中介了总体 PTSD 症状和愤怒反应。进一步的分析检验了 PTSD 分量表评分与愤怒之间的这种中介作用。反刍在分别对 PTSD 各分量表建模时，中介了所有的 PTSD 分量表和愤怒。在调整了其他 PTSD 症状后，只有 2 个 PTSD 症状与愤怒之间的关系仍由反刍所中介：认知/情绪的负性改变和生理唤醒。
在 PTSD 和愤怒症状的背景下应评估反刍，特别是 PTSD 中的生理唤醒和负性情绪/认知症状。（PsycInfo 数据库记录（c）2020 APA，保留所有权利）。
