自主神经系统对二次接触灾害相关图像的反应
Autonomic nervous system reactions to secondary exposure to disaster-related imagery.
摘要(中文译文)
本研究探讨了在间接暴露于2011年东日本大地震（GEJE）的个体中，灾害相关影像如何影响情绪和自主神经系统（ANS）反应，采用心率（HR）和心率变异性（HRV）进行评估。三十六名健康成人在东日本大地震期间经历过强烈地面震动，但未直接遭遇海啸，他们观看了四类视频：自然风景（中性）、地震场景、海啸影像以及灾后反复播出的宣传视频。在每段视频播放前、播放期间和播放后，测量主观情绪反应（状态-特质焦虑量表、正负性情绪量表）、心率及心率变异性指标。与中性视频相比，灾害相关视频在观看期间显著降低心率和心率变异性，提示定向或冻结型自主神经系统反应。地震影像可能唤起自传体恐惧，主要抑制副交感指标；而海啸影像与替代性恐惧相关，主要抑制交感活动。观看结束后即刻，交感激活显著增加，符合反弹式主动防御模式。值得注意的是，宣传视频未引起主观痛苦，但仍改变了心率和心率变异性指标，提示无意识的生理反应性。灾害相关影像根据情绪内容和观看者的创伤史引发不同的自主神经系统反应。自传体恐惧和替代性恐惧可能分别对交感和副交感抑制产生不同影响。此外，这项横断面评估表明，灾后数年看似非侵入性的媒体暴露仍可触发自主神经变化。这些发现强调，在地震和气候灾难后，迫切需要适当的媒体播出指南以保护公众健康。
Abstract
This study investigated how disaster-related imagery affects emotional and autonomic nervous system (ANS) responses, using heart rate (HR) and heart rate variability (HRV), in individuals with indirect exposure to the 2011 Great East Japan Earthquake (GEJE). Thirty-six healthy adults who had experienced strong ground shaking during the GEJE, but not the tsunami directly, viewed four types of videos: natural scenery (neutral), earthquake scenes, tsunami footage, and promotional videos repeatedly broadcast after the disaster. Subjective emotional responses (State-Trait Anxiety Inventory, Positive and Negative Affect Schedule), HR, and HRV indices were measured before, during, and after each video. Compared to the neutral video, disaster-related videos significantly decreased HR and HRV during viewing, indicating an orienting or freeze-type ANS response. Earthquake footage, likely to evoke autobiographic fear, predominantly suppressed parasympathetic indices, while tsunami footage, associated with vicarious fear, predominantly suppressed sympathetic activity. Immediately after viewing, sympathetic activation increased significantly, consistent with a rebound active defense pattern. Notably, promotional videos did not induce subjective distress but still altered HR and HRV indices, suggesting unconscious physiological reactivity. Disaster-related imagery evokes distinct ANS responses depending on the emotional content and the viewer's trauma history. Autobiographic and vicarious fear may differentially affect sympathetic and parasympathetic suppression, respectively. Furthermore, this cross-sectional evaluation demonstrates that even seemingly non-invasive media exposure years after a disaster can trigger autonomic changes. These findings underscore the urgent need for appropriate media broadcasting guidelines to protect public health following both seismic and climatic catastrophes.
