Abstract

Objective: Network analyses showed that the posttraumatic stress disorder (PTSD) symptom structures may vary across traumatic events and types of survivors. However, the structure of PTSD symptoms in COVID-19 bereavement remains unknown. This study aimed to depict the structure of the PTSD symptom network and illuminate how the quality of the predeath relationship between the bereaved and the deceased links to the PTSD symptom network.

Method: Using self-reported data from 408 COVID-19 bereaved adults (225 male and 183 female) collected within 9-month postbereavement, we constructed two graphical lasso networks of PTSD symptoms.

Results: Symptoms with the highest centrality were exaggerated startle, negative emotional states, and reckless/self-destructive behavior, with exaggerated startle having relatively low predictability. The strongest connections were found between exaggerated starkness and detachment, and between psychological cue response and thoughts of avoidance. Moreover, closeness to and conflict with the deceased were linked to the PTSD symptom network through nightmares and physiological cue reactivity, respectively.

Conclusions: This study extends our understanding of what PTSD is for people who are bereaved due to the COVID-19 pandemic by unveiling the structure of the PTSD symptom network. It also helps to distinguish the symptom-level links between quality of relationship with deceased and PTSD among the bereaved. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

对 COVID-19 丧亲成年人的创伤后应激症状和与逝者关系质量的网络分析。

目的：网络分析显示，创伤后应激障碍（PTSD）症状结构可能因创伤事件和幸存者类型而异。然而，COVID-19 丧亲创伤后应激障碍症状的结构仍然未知。本研究旨在描绘创伤后应激障碍症状网络的结构，并阐明丧亲者与逝者之间逝世前关系的质量如何与创伤后应激障碍症状网络相关联：通过收集408名COVID-19丧亲成年人（225名男性和183名女性）在丧亲后9个月内的自我报告数据，我们构建了两个创伤后应激障碍症状拉索网络图：中心度最高的症状是夸张性惊吓、负面情绪状态和鲁莽/自毁行为，其中夸张性惊吓的可预测性相对较低。夸张惊恐与疏离之间、心理暗示反应与回避想法之间的联系最强。此外，与逝者的亲密关系和冲突分别通过噩梦和生理线索反应与创伤后应激障碍症状网络相关联：本研究通过揭示创伤后应激障碍症状网络的结构，扩展了我们对因 COVID-19 大流行而失去亲人者的创伤后应激障碍的理解。它还有助于区分丧亲者与逝者关系的质量与创伤后应激障碍之间在症状层面的联系。(PsycInfo Database Record (c) 2024 APA, 版权所有）。
