Background

The Fukushima Nuclear Energy Workers' Support study showed the Fukushima nuclear disaster caused psychological distress in the workers, with higher rates of post-traumatic stress responses (PTSR). To understand how the type and duration of emergency recovery work performed immediately following this disaster impacted workers’ psychological status, a longitudinal analysis was conducted with 4-year follow-up data since 2011.

Method

Fukushima Daiichi nuclear power plant workers were assessed annually with general psychological distress (GPD) and PTSR questionnaires between 2011 and 2014. Combined, 697 Fukushima Daiichi plant workers provided baseline GPD and PTSR in 2011 and their record of working days for approximately one month immediately following the disaster. The relationship between type of emergency recovery work, working days immediately following the disaster, and psychological distress over four years was analyzed using a mixed effects logistic regression model.

Results

At baseline, GPD and PTSR scores were significantly higher in nuclear power plant workers who worked 3–5 days immediately following the disaster compared to those who worked only 0–2, particularly in the field engineer subgroup. The effect of working days on GPD remained for over a year, and the impact on PTSR remained significant throughout the four years of observation after the disaster.

Conclusions

The Fukushima Daiichi plant field engineers showed significantly higher psychological distress than other workers. The impact of emergency recovery work on psychological distress persisted for over one year, but PTSR in field engineer workers remained significantly elevated four years after the disaster.

紧急恢复工作的类型和持续时间及其对福岛第一核电站工人心理健康症状的纵向影响：福岛新闻项目研究

背景

福岛核能工人支持研究表明，福岛核灾难对工人造成了心理困扰，创伤后应激反应 (PTSR) 发生率较高。为了了解灾难发生后紧急恢复工作的类型和持续时间如何影响工人的心理状态，我们对自 2011 年以来的 4 年随访数据进行了纵向分析。

方法

福岛第一核电站工人在 2011 年至 2014 年期间每年接受一般心理困扰 (GPD) 和 PTSR 问卷调查。 总共有 697 名福岛第一核电站工人提供了 2011 年的基线 GPD 和 PTSR 以及他们紧随其后大约一个月的工作日记录灾难。使用混合效应逻辑回归模型分析紧急恢复工作类型、灾难后立即工作日和四年内心理困扰之间的关系。

结果

在基线时，与仅工作 0-2 天的核电厂工人相比，灾难发生后立即工作 3-5 天的核电厂工人的 GPD 和 PTSR 得分显着更高，尤其是在现场工程师小组中。工作日对 GPD 的影响持续了一年多，在灾后四年的观察中，对 PTSR 的影响仍然显着。

结论

福岛第一核电站现场工程师表现出的心理困扰明显高于其他工人。紧急恢复工作对心理困扰的影响持续了一年多，但在灾难发生四年后，现场工程师的 PTSR 仍然显着升高。
