Predictive factors including risk perception for mid-term mental health after a nuclear disaster remain unknown. The purpose of this study was to examine the association between perceived radiation risk and other factors at baseline and mid-term mental health after the Fukushima Daiichi nuclear disaster of 2011 in Japan. A mail-based questionnaire survey was conducted in January 2012 and January 2013. Mental health status was assessed using the K6 scale. Psychological distress over the 2-year period was categorized into the following four groups: chronic, recovered, resistant, or worsened. Most participants (80.3%) were resistant to the disaster. A positive association was found between the radiation risk perception regarding immediate effects and the worsened group in women. Baseline post-traumatic stress disorder (PTSD) or a history of psychiatric disease predicted being in the chronic or worsened group in mid-term course. These results suggest that evacuees who believed that their health was substantially affected by the nuclear disaster were at an increased risk of having poor mid-term mental health in women. Careful assessment of risk perception after a nuclear disaster, including the presence of PTSD or a history of psychiatric disease, is needed for appropriate interventions.
包括核灾难后中期心理健康风险认知在内的预测因素仍然未知。本研究的目的是探讨2011年日本福岛第一核电站核灾难后，基线时的辐射风险认知及其他因素与中期心理健康之间的关联。2012年1月和2013年1月进行了基于邮件的问卷调查。使用K6量表评估心理健康状况。将两年期间的心理困扰分为以下四组：慢性、康复、抵抗或恶化。大多数参与者（80.3%）对灾难具有抵抗力。在女性中，关于即时影响的辐射风险认知与恶化组之间存在正相关。基线创伤后应激障碍（PTSD）或精神疾病史预示着在中期病程中处于慢性或恶化组。这些结果表明，认为自己的健康受到核灾难严重影响的女性撤离者中期心理健康状况不佳的风险增加。为了进行适当的干预，需要仔细评估核灾难后的风险认知，包括PTSD的存在或精神疾病史。
