ABSTRACT
Objective To analyze the relationship among perceived stress, resilience and sleep quality in patients with coronary heart disease, and to examine the mediating effect of resilience between perceived stress and sleep quality. Methods Totally 231 patients with coronaryheartdisease were selected. The Pittsburgh Sleep Quality Index (PSQI), Perceived Stress Scale (PSS), and 10-item Connor-Davidson Resilience Scale (CD-RISC-10) were used to assess the sleep quality, perceived stress and resilience respectively. Results The average scores of PSQI were (7.2 ± 2.8) points, and 71.4％ (165/231) of the participants had sleep problems (PSQI>5). CD-RISC-10 scores were negatively correlated with PSQI scores and PSS scores (r=-0.62,-0.43, P<0.01), and PSS scores were positively correlated with PSQI scores (r=0.33, P<0.01). Furthermore, Bootstrap-generated 95％CI was (0.130-0.319, P<0.01) and did not include 0, which indicated that resilience significantly mediated the relationship between perceived stress and sleep quality. The mediating effect size of resilience was 56.1％. Conclusion It suggests that patients with coronary heart disease have poor sleep quality. Perceived stress and resilience could affect sleep quality, and resilience could mediate the relationship between perceived stress and sleep quality.
ABSTRACT
Objective To investigate the job stressors and burnout of senior nurses, and explore the possible strategies for alleviating stress and reduction of demission rate of senior nurses. Methods Two hundred and thirty head nurses and senior nurses were included in this study. Nurse Job Stressors Inventory (NJSI) and Maslach Burnout Inventory (MBI) were applied to evaluate the burnout and work-related stress of nurses with the combination of convenience sampling and cluster sampling. Results The NJSI scores of senior nurses and head nurses were (2.62 ± 0.56) points, (2.45 ± 0.47) points, the two scores were significantly different (t=-2.465,P<0.05); the scores of three dimensions of MBI in senior nurses were (30.01±11.86) points, (8.01±5.74) points, (35.35±9.57) points, while the scores in head nurses were (21.65±10.39) points, (5.14±3.37) points, (38.81±8.45) points. Statistically significant difference was seen between the two groups (t=-5.261,-4.705, 2.691,P<0.05). There was a higher positive correlation between job stressors and burnout of senior nurses (r=0.521) than head nurses (r=0.432). Conclusions The level of job burnout is higher in senior nurses than head nurses, attributing to the higher controllability of head nurses. It is suggested to reduce the job burnout of senior nurses and to keep senior nurses in the profession fields, based on the theory of magnetic hospital.
