Media-triggered mental disorders are common when people experience traumatic events. However, few studies have examined the underlying mechanism of how viewing disaster-related short videos triggers psychiatric reactions among non-exposed populations in the context of today's media ecology. Moreover, limited studies have employed psychological network analysis to comprehensively disentangle the associations between diverse forms of media exposure and psychological symptoms. To fill these research gaps, we conducted a survey on a non-exposed population (N = 516) during the 2021 Henan floods to test the effects of short video exposure on its mental status. Short video exposure behaviors were measured under 12 different scenarios, and the participants' mental status (i.e., depression, anxiety, and post-traumatic stress disorder [PTSD]) was measured using the nine-item Patient Health Questionnaire (PHQ-9), seven-item Generalized Anxiety Disorder (GAD-7) scale, and PTSD Check List-Civilian version (PCL-C). We employed both correlation and psychological network analyses to make estimations. The descriptive results revealed that short video exposure behaviors among almost all scenarios were positively associated with the scores of PHQ-9, GAD-7, and PCL-C. The network analysis revealed that both depression and anxiety were associated with the "Support (SVP)" scenario, whereas PTSD was directly linked to the "Help Seeking (SVP)" scenario. Among the three networks, "Help Seeking (SVP)" was the most central among the 12 scenarios of short video exposure. The central symptoms for depression, anxiety, and PTSD were "Concentration," "Relax," and "Reliving Trauma," respectively. The shortest paths between the central short video exposure item and central symptom among the three networks consisted of only two or three steps. This study's findings could assist researchers and policymakers in undertaking novel disaster-related practical activities worldwide.
当人们经历创伤性事件时，媒体引发的精神障碍很常见。然而，在当今媒体生态环境下，很少有研究探讨观看与灾难相关的短视频如何在未暴露人群中引发精神反应的潜在机制。此外，运用心理网络分析来全面梳理不同形式的媒体接触与心理症状之间关联的研究也很有限。为填补这些研究空白，我们在2021年河南洪灾期间对未暴露人群（N = 516）进行了一项调查，以测试短视频接触对其心理状态的影响。在12种不同场景下测量短视频接触行为，并用九项患者健康问卷（PHQ - 9）、七项广泛性焦虑障碍（GAD - 7）量表和创伤后应激障碍检查表 - 平民版（PCL - C）测量参与者的心理状态。我们运用相关性分析和心理网络分析进行评估。描述性结果显示，几乎所有场景下的短视频接触行为都与PHQ - 9、GAD - 7和PCL - C的得分呈正相关。网络分析表明，抑郁和焦虑都与“支持（SVP）”场景相关，而创伤后应激障碍直接与“寻求帮助（SVP）”场景相关。在这三个网络中，“寻求帮助（SVP）”在短视频接触的12种场景中最为核心。抑郁、焦虑和创伤后应激障碍的核心症状分别是“注意力集中”、“放松”和“重温创伤”。三个网络中，核心短视频接触项目与核心症状之间的最短路径仅由两到三步组成。本研究的结果可以帮助研究人员和政策制定者在全球范围内开展与灾难相关的新实践活动。
