Research has demonstrated that posttraumatic stress disorder (PTSD) is associated with internet-related problematic behaviors. However, studies have not explored the linkage between PTSD symptoms and internet gaming disorder (IGD) symptoms. The current study aimed to investigate the relationship between posttraumatic stress symptoms (PTSS) and IGD symptoms via network analysis. We conducted a cross-sectional study with 341 Chinese young adults directly exposed to a typhoon and examined the network structure of PTSS and IGD symptoms, along with bridge symptoms, to elucidate how they co-occur. Results indicated that 'avoiding external reminders' and 'anhedonia' were identified as the most central symptoms in the PTSD network, whereas 'preoccupation,' 'gaming despite harms', and 'loss of control' ranked highest on centrality in the IGD network. Two bridge symptoms emerged within the combined PTSD and IGD network model: 'concentration difficulties' and 'conflict due to gaming' from among the PTSS and IGD symptoms, respectively. These findings reveal novel associations between PTSS and IGD symptoms and provide an empirically-based hypothesis for how these two disorders may co-occur among individuals exposed to natural disasters.
研究表明，创伤后应激障碍（PTSD）与与互联网相关的问题行为有关。然而，目前的研究尚未探讨 PTSD 症状与网络成瘾障碍（IGD）症状之间的联系。本研究旨在通过网络分析探讨创伤后应激症状（PTSS）与网络成瘾障碍症状之间的关系。我们对 341 名直接遭受台风影响的中国年轻人进行了一项横断面研究，考察了 PTSS 和 IGD 症状的网络结构，以及桥梁症状，以阐明它们是如何共同发生的。结果表明，“回避外部提醒”和“快感缺失”被确定为 PTSD 网络中的最核心症状，而“专注”、“不顾伤害而玩游戏”和“无法控制”在 IGD 网络中则处于最高的中心性地位。在 PTSD 和 IGD 的联合网络模型中出现了两个桥梁症状：“注意力困难”和“因玩游戏而产生的冲突”，分别来自于 PTSS 和 IGD 症状。这些发现揭示了 PTSD 和 IGD 症状之间的新关联，并为研究人员提供了一个基于经验的假设，即自然灾害暴露个体中这两种障碍可能如何共同发生。
