Psychological distress among tsunami refugees from the Great East Japan earthquake

Abstract

BackgroundThe 2011 Great Japan tsunami and nuclear leaks displaced 300 000 people, but there are no large studies of psychological distress suffered by these refugees.AimsTo provide a first assessment of major factors associated with distress and dysfunctional behaviour following the disasters.MethodAll refugee families living in Miyagi were sent a questionnaire 10–12 months after the disasters. 21 981 participants (73%) returned questionnaires. Questions assessed psychological distress (Kessler Psychological Distress Scale, K6), dysfunctional behaviours, demographics, event exposure, change in physical activity, household visitors and emotional support.ResultsNine percent scored 13+ on the K6 indicating risk of severe mental illness. Psychological distress was greater among Fukushima refugees. Demographic variables, family loss, illness history and change in physical activity were associated with psychological distress and dysfunctional behaviours. Associations between psychological distress and dysfunction and visitors/supporters depended on relation to supporter.ConclusionsPractitioners need to recognise existing disease burden, community histories and family roles when intervening following disasters.
