This might contribute to occupational stress and adverse psychological outcomes. However, the mechanisms linking this exposure to depressive symptoms remain unclear. This study examines the association between perceived mortality exposure and depressive symptoms and the mediating roles of life satisfaction and sleep quality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional study was conducted among 200 nurses using an online survey.

Life satisfaction was inversely associated with depressive symptoms, whereas sleep quality was not. Nonetheless, the overall regression model, including perceived mortality exposure and life satisfaction, explained only a modest proportion of the variance in depressive symptoms. The mediation analysis showed no significant indirect effects through life satisfaction or sleep quality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
