【 摘 要 】

Living in temporary housing is a risk factor for psychological distress after a natural disaster. As temporary housing is an essential resource for those affected by disasters, investigation of factors which potentially mediate living in temporary housing and psychological distress is needed. This is a cohort study in general population of areas affected by the Great East Japan Earthquake in 2011. Data were obtained from self-report questionnaires in annual health checks between 2014 and 2016 regarding residential situation (e.g., prefabricated or privately-rented temporary housing), psychological distress, sleep disturbances, social support, and covariates. Mediation effects of sleep disturbances and social support on the relationship between temporary housing and psychological distress were evaluated using a cross-lagged panel model during three time points. Among 3,116 participants in 2014, approximately 12% lived in prefabricated or privately-rented temporary housing. Living in prefabricated (β = 0.046, p = 0.031) and privately-rented temporary housing (β = 0.043, p = 0.042) predicted later psychological distress. There was no mediation effect by sleep disturbances (prefabricated temporary housing: β = 0.001, p = 0.620; privately-rented temporary housing: β = −0.001, p = 0.467) or social support (prefabricated temporary housing: β < 0.001, p = 0.748; privately-rented temporary housing: β < 0.001, p = 0.435). CLPM also showed no relationship between living in temporary housing and increased sleep problems or decreased social support. Mental health support may be required for residents who lived in prefabricated or privately-rented temporary housing three years after a natural disaster, whereas support focusing only on sleep disturbances or social support in residents who lived in temporary housing may not be enough to contribute to reducing psychological distress.
