创伤后应激障碍（PTSD）是一种严重的精神障碍，其特征是令人痛苦的入侵。由于并非所有受创伤的人都会患上创伤后应激障碍（PTSD），因此了解其潜在的风险因素非常重要。到目前为止，已经确定了一些心理和生理危险因素。然而，这些因素很少被一起研究。创伤电影范式是前瞻性评估模拟 PTSD 的一个绝佳工具。这项研究检查了 60 名健康参与者在观看“创伤性”电影片段之前、期间和之后的相关心理和生理因素，包括沉思、解离、焦虑、情绪、皮质醇和心理生理学指标。此外，我们在“创伤”后一周评估了入侵行为并实施了修订后的事件影响量表（IES-R）。令人惊讶的是，入侵频率和 IES-R 的唯一重要预测因素是对电影的沉思（状态沉思）。此外，观看电影剪辑后的状态沉思和焦虑的增加都可以预测入侵困扰。我们的研究强调了沉思与创伤后应激障碍的相关性。进一步针对 PTSD 患者精心设计的临床研究应该前瞻性地调查这些关键变量，以证实我们的研究结果。 (C) 版权所有 2017 Textrum Ltd。保留所有权利。
Posttraumatic Stress Disorder (PTSD) is a severe mental disorder characterized by distressing intrusions. Since not all traumatized individuals develop PTSD, it is important to understand its underlying risk factors. So far, several psychological and physiological risk factors have been identified. However, these factors have rarely been examined together. An excellent tool to assess analogue PTSD in a prospective manner is the trauma film paradigm. This study examined relevant psychological and physiological factors in 60 healthy participants before, during and after the presentation of a "traumatic" film clip, including rumination, dissociation, anxiety, mood, cortisol and psychophysiology measures. Moreover, we assessed intrusions and administered the Impact of Event Scale Revised (IES-R) for one week following the "trauma". Surprisingly, the only significant predictor for both intrusion frequency and IES-R was rumination about the film (state rumination). Furthermore, intrusion distress was predicted by both state rumination and an increase in anxiety after the film clip. Our study highlights the relevance of rumination in PTSD. Further well designed clinical studies with PTSD patients should investigate these key variables prospectively to confirm our findings. (C) Copyright 2017 Textrum Ltd. All rights reserved.
