As an exploitable positive psychological state that individual performs during growth and development processes, psychological capital (PsyCap) was deemed as an essential factor in occupational health. This study aims to explore mediating effects of PsyCap on the relationship between job stress and coping style among ICU nurses. A cross-sectional sample of 288 nurses was recruited. A high-level of occupational stress (2.32 ± 0.69) and PsyCap (4.62 ± 0.93) were found among participants who mainly used a positive coping style (2.04 ± 0.59). PsyCap was significantly negatively correlated with job stress (β = -0.250; p < .01) and positively with coping style (β = 0.416; p < .01). Structural equation model analysis revealed that job stress negatively influenced PsyCap, while PsyCap positively influenced coping style. Results verified the mediating role of PsyCap and suggested that an increase in PsyCap contributes to better control of job stress and the improvement of one's coping style.
