A network perspective may shed light on the understanding of Internet-based CBT efficacy for social anxiety disorder. Previous cross-sectional evidence revealed a densely interconnected network for individuals with social anxiety. Yet, longitudinal network changes before and after ICBT are lacking. This study aimed to investigate pathological network changes with Graphical Gaussian Model among patients with social anxiety disorder (n = 249). Social phobia scale (SPS) and Social interaction anxiety scale (SIAS) were measured before and after 8 weeks Internet-based CBT. Results revealed the connection between symptom tension when speaking and symptom awkward when being watched was the most robust edges during ICBT interventions. The pathological network benefited from ICBT and exhibited modification in several prominent interconnections. The overall network connectivity continues to exhibit comparable strength after ICBT. This study represents the first examination of social anxiety network changes after patients with SAD completed a systematic ICBT. Changes in critical edges and nodes provide valuable insights for the design and efficacy assessment of ICBT interventions.

网络视角可能有助于理解基于互联网的 CBT 对社交焦虑症的疗效。之前的横断面证据揭示了社交焦虑症患者存在一个紧密相连的网络。然而，ICBT 前后缺乏纵向网络变化。本研究旨在利用图解高斯模型研究社交焦虑障碍患者 (n = 249) 的病理网络变化。在基于互联网的 CBT 8 周之前和之后测量社交恐惧量表 (SPS) 和社交互动焦虑量表 (SIAS)。结果显示，说话时的紧张症状和被观看时的尴尬症状之间的联系是 ICBT 干预期间最有力的边缘。病理网络受益于 ICBT，并在几个突出的互连中表现出修改。ICBT 之后，整体网络连接继续表现出可比的强度。这项研究是对 SAD 患者完成系统性 ICBT 后社交焦虑网络变化的首次检查。关键边缘和节点的变化为 ICBT 干预措施的设计和功效评估提供了宝贵的见解。
