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，因COVID-19 丧亲而引发的创伤后应激障碍症状的结构仍然未知。2023年9月，实验室负责人唐苏勤副教授和东南大学陈楚倩博士在这方面取得新进展，实验室成员吴丽萍参与学习，合作发表了文章“A Network Analysis of Posttraumatic Stress Symptoms and Quality of Relationship With Deceased in COVID-19 Bereaved Adults” ，研究成果在《Psychological Trauma: Theory, Research, Practice, and Policy》杂志在线发表。这项研究通过剖析创伤后应激障碍（PTSD）症状的网络结构，不仅深化了我们对COVID-19疫情中丧亲者PTSD的认识，而且有助于我们区分丧亲者与逝者关系质量与其PTSD症状之间的内在联系，这对于制定更为精准的心理干预措施具有重要意义。
摘要
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.
Clinical Impact Statemen
Facing bereavement-related posttraumatic stress disorder (PTSD), alternation in arousal and reactivity, as well as cognition and mood, may need special attention. In the case of COVID-19, it may be helpful to focus on the “exaggerated starkness—detachment” and “psychological cue reactivity—thoughts of avoidance” symptom links. Evaluating the nature of the relationship between the bereaved and the deceased may also bring insights in improving PTSD symptoms.
