Effects of disaster-related traumatic events on worry about radiation and COVID-19: A decade after the Fukushima nuclear power plant accident.

Community residents exposed to nuclear power plant (NPP) accidents have long-term worry about the effects of radiation. After the 2011 Fukushima NPP accident, those who experienced traumatic events during the Great East Japan Earthquake (GEJE) tended to have greater worry about radiation. Along with the prolonged worry about radiation, there may also be cognitive changes caused by the traumatic events. We hypothesized that if there were cognitive changes underlying the prolonged worry about radiation, those who experienced the traumatic events would tend to have greater worry about other issues unrelated to radiation. We examined the effects of the traumatic events during the GEJE on community residents' worry about radiation and COVID-19 a decade after the Fukushima NPP accident. Using the data of a longitudinal questionnaire survey following a random sample of 4900 community residents outside the evacuation zone in Fukushima, this study analyzed 774 responses (15.8%). The traumatic events consisted of (1) injury, (2) injury or death of a family member, and (3) the loss of a house or other property. We developed a mediation model drawing paths from the traumatic events to worry about radiation and COVID-19, including posttraumatic stress symptoms (PTSS) as a mediator, using structural equation modeling. The traumatic events directly affected worry about radiation. Although it did not directly affect worry about COVID-19, it did so indirectly through worry about radiation and PTSS. Traumatic events can increase trauma-related worry independently of PTSS and increase trauma-unrelated worry indirectly through trauma-related worry and PTSS.

The Tohoku Theater Project in Postdisaster Japan: An Exemplar for Addressing Community Mental Health in the Context of Disaster.

The Tohoku Theater Project was completed 2 years after the natural and nuclear disasters in Tohoku, Japan, on March 11, 2011. It employed the dramatic arts to support the healing process, promote resilience, and increase dialogue and understanding about mental health among individuals who were directly affected by the disasters. The four performances fostered important discussions regarding the psychological impact of the Tohoku disasters. Participants (N=143) found the theater performance effective at facilitating discussion, increasing empathy, and enhancing mental health knowledge, coping, and resilience. The performances provided critical information about access to services; many participants reported that they had not known where to seek help for mental health prior to their involvement with the Tohoku Theater Project. Lessons learned may inform community-based strategies that promote mental health and healing in the wake of the COVID-19 pandemic and other public health disasters.
