Purpose: Nurses are undertaking considerable emotional and physical work, which may lead to unrecoverable fatigue. This study aimed to evaluate the level of chronic fatigue and explore its associated factors among Chinese nurses in the hope of providing scientific evidence for fatigue-reduction strategies. Methods: This cross-sectional study was carried out in Liaoning Province, China in 2018. The study recruited 700 nurses and collected 566 effective respondents. Chronic fatigue, demographic factors, job conditions, and emotional intelligence were assessed through questionnaires. Chronic fatigue was assessed with the Fatigue Scale 11, occupational stress with the Effort–Reward Imbalance Questionnaire, and emotional intelligence with the Wong and Law Emotional Intelligence Scale. Hierarchical multiple regression was used to explore factors related to chronic fatigue and to test the moderating effect of emotional intelligence on the association between occupational stress and chronic fatigue. Simple slope analysis was conducted to visualize the interaction. Results: The mean score of chronic fatigue among the Chinese nurses was 17.14±6.16. Being married, having long weekly work time, working night shifts, and discontent with the nurse–patient relationship were positively associated with chronic fatigue. Effort:reward ratio, overcommitment, and emotional intelligence were important factors related to chronic fatigue. Emotional intelligence played a moderating role in the relationship between the effort:reward ratio and chronic fatigue. When emotional intelligence was higher, the effect of the effort:reward ratio on chronic fatigue became weaker. Conclusion: Most nurses surveyed in China might have relatively high levels of chronic fatigue. Our results highlight the importance of interventions on these factors for the reduction of fatigue among nurses in China. Providing more opportunities and support and developing emotional intelligence are crucial strategies to reduce chronic fatigue among nurses in China.

Background: As experts studying occupational health psychology know, low level of work engagement leads to higher turnover intentions. Some researchers have put a focus on the association between organizational support and work engagement. However, little has been done concerning the mediating effect of psychological capital (PsyCap) on the association between perceived organizational support (POS) and work engagement (vigor, dedication, absorption) among Chinese doctors. Methods:A cross-sectional study has been carried out from November to December in 2017, in Liaoning Province, China. The questionnaire consists of Survey of Perceived Organizational Support, the Utrecht Work Engagement Scale, Psychological Capital Questionnaire, and demographic and working variables. The self-administered questionnaires were distributed to 1,009 doctors. Effective responses were collected from 836 participants (82.85%). Hierarchical multiple regression and the asymptotic and resampling strategies were used to examine the association between POS and work engagement mediated by PsyCap.Results: After controlling the demographic and working variables, POS was positively related to vigor (β = 0.402, P < 0.01), dedication (β = 0.413, P < 0.01), and absorption (β = 0.373, P < 0.01). Psychological capital was positively associated with vigor (β = 0.442, P < 0.001), dedication (β = 0.413, P < 0.001), and absorption (β = 0.395, P < 0.001). Thus, PsyCap [a × b = 0.1895, bias-corrected and accelerated 95% confidence interval (BCa 95% CI) = 0.1524, 0.2290]; a × b = 0.1517, BCa 95% CI = 0.1180, 0.1875; a × b = 0.1693, BCa 95% CI = 0.1299, 0.2099] significantly mediated the association between POS and vigor, dedication, and absorption, respectively. Conclusion:There was a low level of work engagement among Chinese doctors. Perceived organizational support could indirectly improve vigor, dedication, and absorption, partially through mediator PsyCap. Perceived organizational support intervention, education, and training in PsyCap should be carried out to cope with work engagement.

Background: Workplace violence (WPV) and psychological capital (PsyCap) are linked to professional identity, however, little research has examined how WPV is associated with professional identity via PsyCap. This study is aimed to examine the association between WPV and professional identity, and to further explore whether PsyCap can serve as a mediator between WPV and professional identity among Chinese doctors. Materials and methods: A cross-sectional study was conducted from November to December in Liaoning Province in China, in 2017. The study used a questionnaire consisting of Workplace Violence Scale (WVS), Occupational Identity Scale (OIS), Psychological Capital Questionnaire (PCQ), as well as questions about demographic characteristics. Out of 1200 doctors, 995 (effective response rate of 82.92%) completed the questionnaire survey and became our final subjects. Hierarchical multiple regression and the asymptotic and resampling strategies were conducted to explore the mediating role of PsyCap in the relationship between WPV and professional identity. Results: After adjusting for demographic characteristics, WPV was negatively associated with professional identity (β=−0.37; P <0.01). Mediation analysis indicated that PsyCap was a mediator in the relationship between WPV and professional identity. Two dimensions of PsyCap: self-efficacy (a*b =−0.04, BCa 95% CI: (−0.08, −0.01); P <0.01) and hope (a*b =−0.04, BCa 95% CI: (−0.08, −0.01); P <0.01) also did exhibit mediating effects in the relationship between WPV and professional identity. The proportion of self-efficacy, hope and PsyCap mediation was 10.73%, 10.77%, 36.22% for professional identity respectively. Conclusion: These results provided evidence that PsyCap could mediate the association between WPV and professional identity. To increase the level of professional identity, positive interventions targeting PsyCap should be taken, with a focus on self-efficacy and hope.

Purpose: Centers for Disease Control and Prevention (CDC) is playing a vital role in protecting public health and safety. However, few studies have researched on the occupational burnout of CDC employees in the world. Previous studies have reported that transformational leadership could improve the level of psychological empowerment and ameliorate burnout of the employees. In this study, we aimed to analyze the association between transformational leadership and burnout and to test the mediating role of psychological empowerment in this relationship among CDC employees in China. Methods: Maslach Burnout Inventory-Human Service Survey, Transformational Leadership Questionnaire, and Psychological Empowerment Scale were used to measure burnout, transformational leadership, and psychological empowerment. A total of 385 CDC employees (effective response rate: 96.25%) were included in the study. We analyzed the association between transformational leadership and three subscales of burnout with hierarchical linear regression analyses. The mediating role of psychological empowerment was finally examined by asymptotic and resampling strategies. Results: Transformational leadership was negatively associated with emotional exhaustion, depersonalization, and reduced personal accomplishment after controlling sociodemographic and working context characteristics. Transformational leadership and psychological empowerment, respectively, accounted for 9.3% and 12.3% of the variance in emotional exhaustion; 8.5% and 16.7% of the variance in depersonalization; and 6.7% and 10.0% of the variance in reduced personal accomplishment. We found that psychological empowerment played a partially mediating role on the relationship between transformational leadership and burnout. The proportion of psychological empowerment’s mediating effect was 41.56% for emotional exhaustion, 50.62% for depersonalization, and 44.32% for reduced personal accomplishment. Conclusions: It was suggested that transformational leadership could decrease the risk of burnout by the pathway of promoting the employee’s psychological empowerment. Interventions focusing on transformational leadership and psychological empowerment should be of significance to cut burnout.
