Despite previous research has illustrated there is high-coexistence between posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) in the aftermath of traumatic events, few studies have conceptualized the coexistence mechanism of the two psychological phenomena. Using the network analysis, this study aimed to identify the key bridge symptoms and compare sex differences between PTSD symptoms and PTG elements in survivors 10 years after the Wenchuan earthquake in China. A total of 744 survivors 10 years after the Wenchuan earthquake in China completed self-reported questionnaires on demographics, PTSD symptoms (4-item of Posttraumatic Stress Disorder Checklist), and PTG (10-item of Posttraumatic Growth Inventory). Network analysis was used to identify the network structure of PTSD symptoms and elements of PTG, along with bridge symptoms. Additionally, sex differences in the network structure were compared by the Network Comparison Test. Results revealed that the network of PTSD symptoms and elements of PTG was robust to stability and accuracy tests. The key bridge symptoms in the network were "Stronger religious faith", "Changed priorities", and "Easily startled". There were significant differences in network global strength across sex, and network structure across the severity of property loss other than house damage. Future interventions targeting the three key bridge symptoms are expected to relieve the severity of PTSD and promote growth following exposure to traumatic events.
尽管先前的研究表明，创伤事件后创伤后应激障碍（PTSD）和创伤后成长（PTG）高度共存，但很少有研究对这两种心理现象的共存机制进行概念化。本研究采用网络分析方法，旨在识别关键的桥梁症状，并比较中国汶川地震10年后幸存者中PTSD症状与PTG要素的性别差异。在中国汶川地震10年后，共有744名幸存者完成了关于人口统计学、PTSD症状（创伤后应激障碍检查表4项）和PTG（创伤后成长量表10项）的自我报告问卷。采用网络分析来识别PTSD症状和PTG要素的网络结构以及桥梁症状。此外，通过网络比较测试比较网络结构中的性别差异。结果显示，PTSD症状网络和PTG要素对稳定性和准确性测试具有稳健性。网络中的关键桥梁症状为“更强的宗教信仰”、“优先事项改变”和“容易受惊吓”。性别之间的网络全局强度存在显著差异，除房屋损坏外，网络结构在财产损失严重程度方面也存在差异。针对这三个关键桥梁症状的未来干预措施有望减轻PTSD的严重程度，并促进创伤事件后的成长。
