Objectives: Shift work is a stressful situation. It is important to know the factors associated with the ability to adapt to a shift work schedule. The aim of the present study was to investigate the association between sleep, as well as personality variables, and the resilience of shift work nurses.
Method: Self-report questionnaires were administered to 95 nurses who worked in one national university hospital. Connor-Davidson resilience scale, hospital anxiety and depression scale, morningness-eveningness scale, Pittsburgh sleep quality index, other sleep-related questionnaires, and Korean defense style questionnaires were used.
Results: Age, shift work duration, off-day oversleep, depression, anxiety, adaptive defense style, and self-suppressive defense style were significantly associated with resilience (p ＜ 0.05). Multiple regression analysis showed that age (β = 0.34, p ＜ 0.05), depression (β = -0.25, p ＜ 0.05), adaptive defense style (β = 0.45, p ＜ 0.001), and self-suppressive defense style (β = -0.19, p ＜ 0.05) significantly predicted the resilience of shift work nurses. Concerning individual defense mechanisms, resignation (β = -0.20, p ＜ 0.05), sublimation (β = 0.19, p ＜ 0.05), omnipotence (β = 0.19, p ＜ 0.05), and humor (β = 0.20, p ＜ 0.05) significantly predicted the resiliency.
Conclusion: The findings indicate that a specific defense style and other mechanisms were associated with the resilience of shift work nurses. A future prospective study with more participants could further clarify the relationship between sleep-related variables, as well as personality factors, and resilience of shift work nurses.
