ResultsThe total score of nurses' job performance was(202.22±16.95) points.There were no significant differences in the job performance of nurses with different gender and educational background(P>0.05), while differences in the job performance of nurses with different age, marital status, working year, professional title, department, and monthly income were statistically significant(P < 0.05 to P < 0.01).Pearson correlation analysis showed that the dimensions of nurses' task performance and situational performance were positively correlated with psychological capital, occupational well-being and other dimensions(P < 0.05 to P < 0.01), the anti-production performance was negatively correlated with the hope dimension in psychological capital(P < 0.05), but there was no obvious correlation between the dimensions of task performance and welfare(P>0.05).Multiple linear regression analysis showed that hope, resilience, job value and welfare benefit were the influencing factors of nurses' job performance(P < 0.01), which together explained 50.3% of the total variation.

ConclusionsThe job performance of hospital nurses is at a medium level, which varies with age, marital status, working year, professional title, department, and monthly income.Hope, resilience, job value and welfare are the predictors of nurses'job performance.
