This study investigated the mediating effects of psychological capital appreciation in the relationship between psychological resilience and burnout among ICU nurses. The findings aim to provide an objective reference for hospitals to enhance the occupational health of ICU nurses.
A cross-sectional questionnaire survey was administered to 150 ICU nurses employed at 20 tertiary hospitals across Hebei Province. Stratified random sampling was employed in the sampling methodology, with strata defined by hospital size and ranking. Subsequently, ICU nurses were randomly selected within each stratum to enhance the representativeness of the sample.
(i) Among the 150 nurses, the psychological resilience score was (68.701 ± 14.549), resilience was (63.547 ± 14.020), and burnout score was (65.095 ± 18.461). (ii) The analysis revealed that psychological capital appreciation mediated the relationship between psychological resilience and burnout, with a mediation effect size of 0.597, accounting for 79% of the total effect. (iii) Psychological resilience did not directly affect job burnout (direct effect = 0.148, 95% CI includes 0, = 0.864, = 0.389), but indirectly reduced burnout by enhancing PCA. The indirect effect was significant (indirect effect = 0.601, 95% CI excludes 0, = 6.073, = 0.000), with a total effect size of 0.748 (95% CI excludes 0, = 8.486, = 0.000).
(i) Psychological capital appreciation (PCA) plays a complete mediating role between resilience and job burnout of ICU nurses. (ii) The overall incidence of job burnout among nurses is high, while the levels of resilience and psychological capital appreciation are at a low to medium level, which need to be improved urgently.
本研究探讨心理资本增值在重症监护病房（ICU）护士心理弹性与职业倦怠关系中的中介作用。研究结果旨在为医院提高ICU护士职业健康水平提供客观参考。
对河北省20家三级医院的150名ICU护士进行横断面问卷调查。抽样方法采用分层随机抽样，根据医院规模和排名进行分层。随后，在每个层内随机选择ICU护士，以提高样本的代表性。
（i）150名护士中，心理弹性得分（68.701±14.549），复原力得分（63.547±14.020），职业倦怠得分（65.095±18.461）。（ii）分析表明，心理资本增值在心理弹性与职业倦怠关系中起中介作用，中介效应量为0.597，占总效应的79%。（iii）心理弹性对职业倦怠无直接影响（直接效应=0.148，95%CI包含0，p=0.864，β=0.389），但通过增强心理资本增值间接降低职业倦怠。间接效应显著（间接效应=0.601，95%CI不包含0，p=6.073，β=0.000），总效应量为0.748（95%CI不包含0，p=8.486，β=0.000）。
（i）心理资本增值在ICU护士心理弹性与职业倦怠之间起完全中介作用。（ii）护士职业倦怠总体发生率较高，而心理弹性和心理资本增值水平处于中低水平，亟待提高。
