ABSTRACT

Background: Previous research indicates that PTSD patients may show alterations in interpersonal distance regulation (IDR). However, it is not clear whether altered IDR is correlated with psychopathology after trauma and whether attentional processes might be involved in these alterations.

Objective: The current study investigated IDR and attentional processing in a sample of Israeli firefighters.

Method: Twenty-four participants completed an experimental IDR task as well as measures of PTSD and anxiety. During the task, event-related potentials were recorded to assess attentional processing as reflected in the P1 and N1 components.

Results: Participants who did not choose a closer distance towards friends than strangers experienced greater anxiety. Moreover, participants who showed attentional avoidance towards strangers reported more PTSD symptoms. By contrast, participants who showed hypervigilant attention towards strangers reported greater anxiety.

Conclusions: Our results demonstrate an association between IDR, PTSD, and anxiety after trauma. Future studies should re-investigate these associations in larger samples and explore potential implications for prevention and treatment.

朋友之间没有距离太远:舒适的人际距离与以色列消防员的 PTSD 和焦虑症状的关联

摘要

背景:先前的研究表明,PTSD 患者可能表现出人际距离调节 (IDR) 的改变。然而,尚不清楚改变的 IDR 是否与创伤后的精神病理学相关,以及注意力过程是否可能参与这些改变。

目标:当前的研究调查了以色列消防员样本的 IDR 和注意力处理。

方法: 24 名参与者完成了一项实验性 IDR 任务以及 PTSD 和焦虑的测量。在任务期间,记录事件相关电位以评估 P1 和 N1 组件中反映的注意力处理。

结果:与陌生人相比,没有选择与朋友保持更近距离的参与者经历了更大的焦虑。此外,对陌生人表现出注意力回避的参与者报告了更多的 PTSD 症状。相比之下,对陌生人表现出高度警惕的参与者报告了更大的焦虑。

结论:我们的结果表明 IDR、PTSD 和创伤后焦虑之间存在关联。未来的研究应该在更大的样本中重新调查这些关联,并探索对预防和治疗的潜在影响。
