Abstract:
Since the 2011 Fukushima nuclear power plant accident, multiple social network disruptions have been reported among the community in Fukushima, while posttraumatic stress symptoms among the residents have persisted. In this study, we aimed to explore the influence of time and social networks on the recovery of posttraumatic stress symptoms based on longitudinal data from community residents in Fukushima, following up five to ten years after the nuclear power plant accident. We conducted five questionnaire surveys quasi-annually, the targets of which were randomly sampled 4900 non-evacuee community residents. In this study, the data of 1809 respondents who participated in at least one survey were used (36.9% of the initial target). Setting posttraumatic stress symptoms as the outcome, we examined the interaction between time and social network size using a mixed model, adjusting for sociodemographic characteristics and disaster-related events. Their interaction was statistically significant, and the posttraumatic stress symptoms of those with small social networks persisted, while those with larger social networks recovered. Maintaining and promoting social networks may contribute to mental health recovery after a nuclear disaster.
摘要:
自2011年福岛核电站事故以来,据报道,福岛社区中存在多个社交网络中断,而居民的创伤后应激症状持续存在。在这项研究中,我们旨在探讨时间和社交网络对创伤后应激症状恢复的影响,基于来自福岛社区居民的纵向数据,核电站事故发生五到十年后的后续行动。我们每年进行五次问卷调查,其目标是随机抽取4900名非疏散社区居民。在这项研究中,使用了参与至少一项调查的1809名受访者的数据(最初目标的36.9%).设定创伤后应激症状作为结果,我们使用混合模型研究了时间和社交网络大小之间的相互作用,适应社会人口特征和灾害相关事件。它们的相互作用具有统计学意义,那些社交网络较小的人的创伤后应激症状持续存在,而那些拥有更大社交网络的人康复了。维护和促进社交网络可能有助于核灾难后的心理健康恢复。
