Introduction
The global healthcare system is currently in the midst of a significant shortage of professional nurses, a crisis that is estimated to reach a deficit of 13 million in the near future [
1]. This shortage is largely attributed to an aging population and the enduring effects of the COVID-19 pandemic [
2]. The high nursing turnover rates, which significantly contribute to this shortage [
3], not only increase nursing errors and clinical workloads but also reduce the quality of care, patient satisfaction, and nurse career development [
4‐
6], while imposing substantial financial burdens on healthcare systems due to the costs of recruiting and training new staff [
7,
8]. This creates a vicious cycle of diminished team efficiency and morale, further exacerbating turnover [
9,
10]. Turnover intentions among nurses, defined as the likelihood of nurses permanently leaving their positions, are robust predictors of actual turnover [
11]. Investigating these intentions provides valuable insights into employee needs, forming the basis for effective retention strategies [
12,
13]. Global variation exists in nurse turnover intentions, with notable rates reported in countries such as the United States [
14], China [
15], Japan [
16], and Thailand [
17], particularly in the wake of the COVID-19 pandemic. Despite extensive research efforts, high turnover rates persist, highlighting the urgent need for a deeper exploration of the factors influencing these intentions and the underlying mechanisms [
18].
Job burnout, characterized by emotional exhaustion, depersonalization, and a diminished sense of personal accomplishment, is a significant predictor of turnover intentions among nurses [
19]. Nurses are more susceptible to burnout due to the demanding nature of their work, which involves sustained patient contact and the provision of continuous care, often under stressful conditions [
20]. The detrimental effects of burnout extend beyond individual well-being, affecting job satisfaction and organizational commitment and ultimately compromising the quality of care and safety [
21‐
23]. Furthermore, the economic implications of burnout-induced turnover are considerable, with estimates indicating an average annual cost of $16,736 per nurse [
24]. Given these consequences, it is imperative to identify and address the factors contributing to job burnout to reduce turnover intentions effectively.
Despite the ethical dimensions inherent in nursing practice [
25], the influence of ethical factors on nurse turnover intentions remains underexplored. Understanding the mechanisms by which ethical challenges contribute to turnover intentions could provide valuable insights for developing targeted interventions. In this context, moral resilience has emerged as a beacon of hope, a potential strategy to mitigate the adverse consequences of burnout and subsequent turnover intentions [
26,
27]. Moral resilience refers to the capacity to preserve or restore moral integrity in response to moral complexities, confusion, distress, or setbacks in daily practice [
28]. As a virtue, moral resilience not only protects nurses’ well-being and professional values but also enhance their ability to deliver high-quality care [
29]. It plays a crucial role in managing ethical dilemmas, reducing psychological distress, and preventing personal injury [
30]. Although interdisciplinary research suggests a negative correlation between moral resilience and both job burnout and turnover intentions, empirical studies specifically focusing on registered nurses are scarce, highlighting the need for further investigation.
The Job Demands-Resources (JD-R) model provides a comprehensive framework for understanding the interplay between job demands, job resources, and their impact on burnout and turnover intentions [
31]. According to this model, job demands, such as work intensity, emotional stress, and ethical conflicts, require sustained physical or psychological effort, leading to physiological and psychological costs, including fatigue, anxiety, and burnout [
32]. Conversely, job resources, which facilitate goal achievement and foster personal growth, can buffer the impact of job demands, thereby reducing the likelihood of burnout [
33]. Within this framework, burnout is a critical outcome that can impair physical and emotional health [
34], diminish job satisfaction, and increase the propensity for absenteeism and turnover [
35,
36].
Moral resilience can be conceptualized as a job resource within the JD-R model [
37]. As a significant personal trait, moral resilience equips individuals with job demands, mitigates burnout, and maintains work engagement. This is particularly pertinent in healthcare settings, where ethical dilemmas and moral distress are frequently encountered [
26]. Theoretical perspectives suggest that individuals with higher moral resilience can better manage moral distress, reducing the risk of burnout and the associated turnover intentions [
27,
38]. This capacity to maintain moral integrity and a strong sense of job embeddedness may explain the protective role of moral resilience against job burnout and turnover intentions [
39].
Empirical evidence supports these theoretical propositions. Studies indicate that healthcare professionals with higher levels of moral resilience experience lower levels of burnout and are less likely to develop turnover intentions and alleviate moral distress, thereby reducing burnout [
11,
20]. Furthermore, research consistently demonstrates that burnout significantly predicts turnover intentions [
40]. For example, in social work, professionals experiencing high levels of burnout are more likely to express intentions to leave their positions, with job satisfaction often mediating this relationship [
41].
Despite the growing body of research, the specific pathways through which moral resilience influences turnover intentions via job burnout still need to be explored, particularly in nursing. The JD-R model provides a robust theoretical basis for investigating these relationships. By examining how job resources, such as moral resilience, can counteract job demands and reduce burnout, this study aims to elucidate their impact on turnover intentions among nurses. To address this gap, we propose the following hypotheses: (1) nurses’ moral resilience is negatively associated with their job burnout and turnover intentions, and (2) job burnout mediates the relationship between moral resilience and turnover intentions among registered nurses.
Discussion
This study demonstrates that nurses’ moral resilience is negatively related to both job burnout and turnover intentions; job burnout is also negatively associated with turnover intentions. Furthermore, our findings reveal that job burnout fully mediates the relationship between moral resilience and turnover intentions. Further analysis indicates that only depersonalization fully mediates the specific relationship among three dimensions of job burnout. At the same time, emotional exhaustion and reduced personal accomplishment do not exhibit significant mediating effects. These findings contribute to the theoretical understanding of the JD-R model by illustrating how moral resilience, as a crucial job resource, can mitigate the detrimental effects of job demands, such as emotional stress and ethical conflicts, on job burnout and turnover intentions.
The first key finding is the negative association between nurses’ moral resilience and turnover intentions, consistent with previous studies conducted in the post-COVID-19 era [
20] and among interdisciplinary healthcare professionals [
27]. Nurses frequently encounter ethical challenges that can lead to moral distress, injury, and residue [
59]. Moral resilience, defined as maintaining or restoring moral integrity in the face of such challenges [
60], is vital for sustaining emotional and psychological well-being and career development [
39]. Increased moral resilience has been shown to enhance nurses’ work engagement, thereby reducing their intentions to leave their profession [
39]. Furthermore, moral resilience improves ethical judgment and self-regulation, allowing nurses to respond more effectively to ethical challenges, further reducing turnover intentions [
26,
28]. These findings underscore the role of moral resilience as a crucial job resource that mitigates job demands and reduces turnover intentions, offering practical implications for nurse retention strategies.
The study also confirms the positive correlation between job burnout and turnover intentions, aligning with existing studies [
61]. This relationship emphasizes the harmful impact of job burnout on nursing staff turnover, where increased job demands lead to burnout, subsequently raising turnover intentions. Job burnout can impair nurses’ ability to further burnout [
62]. In addition, nurses experiencing burnout may struggle to deliver high-quality care, potentially harming patients and engaging in unethical practices [
40,
63]. High turnover rates exacerbate workforce shortages, compelling remaining staff to shoulder additional workloads, further aggravating burnout and work-life imbalance [
64]. Therefore, it is crucial for nursing administrators to understand the relationship between job burnout and turnover intentions [
65] and to create supportive work environments that alleviate burnout and enhance job satisfaction, thereby reducing turnover.
The third finding of our study is the negative correlation between nurses’ moral resilience and their job burnout, consistent with previous findings [
27,
66]. Healthcare professionals often face moral stressors and ethical dilemmas, such as medical errors, moral uncertainty, and ethical conflicts, which can lead to cognitive dissonance, secondary trauma, and moral distress or injury [
67,
68]. Persistent moral distress and injury can accumulate into moral residue, eventually triggering job burnout [
28,
30,
39]. Our study extends the JD-R model by demonstrating that fostering moral resilience is essential for preventing moral distress, reducing moral injuries, and effectively mitigating job burnout. Moral resilience enables healthcare professionals to navigate ethical complexities better, reducing the accumulation of moral stressors [
28]. As Rushton [
26] highlights, cultivating moral resilience involves deepening the capacity to address ethical challenges rather than avoiding or suppressing them, thereby effectively mitigating the impacts of moral distress and injury. Overall, strengthening the moral resilience of healthcare professionals is pivotal in enhancing their job satisfaction and career longevity, significantly reducing the risk of job burnout and improving overall work efficiency and quality.
Fourth, the study identifies job burnout as a complete mediator of the relationship between moral resilience and turnover intentions. According to the Conservation of Resources Theory [
69], nurses with insufficient moral resilience may struggle when facing ethical challenges [
70,
71], leading to the depletion of critical psychological resources, such as a sense of integrity [
72]. This resource loss can trigger a cascading effect, exacerbating moral distress and job burnout [
73]. The continuous depletion of resources may prompt nurses to consider resigning to avoid further harm [
69]. Therefore, enhancing moral resilience is crucial to breaking this negative cycle by alleviating job burnout and reducing turnover intentions. These findings deepen our understanding of job burnout as a mediating mechanism between moral resilience and turnover intentions and highlight the importance of interventions aimed at boosting moral resilience to reduce nurse turnover rates and improve workforce stability.
Finally, this study reveals that depersonalization, rather than emotional exhaustion or reduced personal accomplishment, mediates the relationship between moral resilience and turnover intentions. Although moral resilience was significantly correlated with all three dimensions of burnout, our findings suggest that depersonalization plays a unique and critical role in this relationship. Previous studies have shown that moral resilience primarily impacts depersonalization and emotional exhaustion dimensions of burnout [
27], a finding supported by a systematic review [
74]. However, our study did not find a mediating effect of emotional exhaustion underscoring the specific influence of depersonalization. This underscores the need for healthcare organizations to develop targeted strategies that address clinical practice’s complex moral and ethical dimensions rather than relying on a generalized approach to support nursing professionals [
27].
This study has several limitations. First, the cross-sectional design precludes the establishment of causal relationships between moral resilience, job burnout, and turnover intention. Future longitudinal studies with larger sample sizes are necessary to validate and deepen our understanding of these relationships. Second, usimg a convenience sampling strategy, while practical and suitable for the study’s objectives, may introduce biases that could compromise the reliability and generalizability of the findings. Lastly, the reliance on self-report questionnaires for data collection presents the risk response bias, which could affect the accuracy of the results.
Conclusions
This study demonstrates that moral resilience is negatively associated with job burnout and turnover intentions among registered nurses. Furthermore, it establishes that job burnout fully mediates the relationship between moral resilience and turnover intentions, thereby enriching our understanding of the dynamics among these three variables. These findings suggest that interventions to enhance moral resilience effectively mitigate job burnout and reduce turnover intentions. Nursing administrators should prioritize creating an ethical work environment and implementing programs that strengthen nurses’ moral competencies through targeted moral education.
Implications for clinical practice
The observed negative relationship between moral resilience and turnover intentions, mediated by the depersonalization dimension of job burnout, highlights the importance of interventions designed to enhance moral resilience among nurses. Clinical administrators and healthcare policymakers should consider implementing targeted training, support systems, and work environments that foster ethical practice and resilience-building activities. Addressing job burnout, which acts as a mediator in this relationship, can effectively reduce turnover intentions, thereby stabilizing the nursing workforce. Resilience training workshops, peer support groups, and organizational changes that reduce workload and enhance job satisfaction are recommended. By improving nurse retention, these interventions will likely enhance patient care quality and overall healthcare outcomes, providing reassurance and confidence to the healthcare community.
Implications for future research
The findings of this study underscore the critical role of moral resilience in reducing job burnout and turnover intentions among nurses, suggesting several avenues for future research. Longitudinal studies are needed to confirm the causal relationships between moral resilience, job burnout, and turnover intentions over time. Intervention studies should be conducted to evaluate the effectiveness of programs that enhance moral resilience in reducing job burnout and turnover intentions. Additionally, future research should explore the specific components of moral resilience that are most effective in these contexts. Examining the influence of organizational and environmental factors on moral resilience and its effects on job burnout and turnover intentions across different healthcare settings and cultural contexts further validates and extends the generalizability of the current findings.
