Abstract

Background: On March 11, 2011, Japan experienced an unprecedented combination of earthquake/tsunami/nuclear accidents (the Great East Japan Earthquake; GEJE). We sought to identify mental health and psychosocial consequences of this compound disaster.

Method: A systematic literature review was conducted of quantitative research articles addressing mental health of survivors and the psychological impact of the GEJE. For articles between March 2011 and December 2014, PubMed, PsychINFO, and EMBASE databases were searched with guidance on literature review method.

Results: Forty-nine studies met the inclusion criteria. A substantial proportion of the affected individuals experienced considerable psychological distress. Mental health outcomes included, but were not limited to, posttraumatic stress disorder, depression, and anxiety symptoms. Physical health changes, such as sleeping and eating disturbances, also occurred. In Fukushima, radioactive release induced massive fear and uncertainty in a large number of people, causing massive distress among the affected residents, especially among mothers of young children and nuclear plant workers. Stigma was additional challenge to the Fukushima residents. The review identified several groups with vulnerabilities, such as disaster workers, children, internally displaced people, patients with psychiatric disorders, and the bereaved.

Conclusions: Following the GEJE, a considerable proportion of the population was mentally affected to a significant degree. The affected individuals showed a wide array of mental and physical consequences. In Fukushima, the impact of nuclear disaster was immense and complex, leading to fear of radiation, safety issues, and stigma issues.

Keywords: Disaster; Earthquake; Fukushima Daiichi nuclear accident; Great East Japan Earthquake; Mental health; Posttraumatic stress disorder; Psychological service; Radiation fear; Tsunami.
