This research examined associations among social support, governmental support, sense of community, and psychological status, including depression and life satisfaction, in Yaan earthquake survivors, based on a cross-sectional survey conducted in June 2014. The survey applied a nonprobability sampling method and a total of 495 survivors aged 18 years and older completed the questionnaire. Regression analyses revealed that social support and sense of community were associated with depression. Sense of community mediated the relationships between depression and both social and governmental support. Governmental support and sense of community were associated with life satisfaction. Sense of community mediated the relationships between life satisfaction and both social and governmental support. The findings suggest that social support, governmental support, and sense of community would enhance the psychological well-being of disaster survivors.
