Does psychological capital mediate the impact of dysfunctional sleep beliefs on well-being?

The influence of sleep on job satisfaction: examining a serial mediation model of psychological capital and burnout

Introduction

This study draws on the conservation of resources theory to investigate whether the loss of sleep can trigger the loss of additional resources that are necessary for work.

Methods

Using cross-sectional design of 322 call center employees working at a government-owned public bank in South Korea, we test the study hypotheses using regression and bootstrapping indirect effects analyses.

Results

The results of analyses show that insufficient sleep increases employee burnout and that psychological capital mediates this relationship. We also find that insufficient sleep decreases job satisfaction via a serial mediation model such that insufficient sleep reduces psychological capital, which in turn increases burnout, and ultimately results in lower job satisfaction.

Discussion

The findings reinforce the previous assessment that although sleep is a non-work factor, its impact spills over to the workplace. Theoretically, this study goes beyond direct effect to uncover the underlying or mediating mechanisms that account for the impact of the sleep-burnout relationship and the sleep-job satisfaction relationship. For managers, the results highlight the significance of sleep to employees' overall health and well-being and thus underscore the need to foster a work culture that recognizes and prioritizes employee sleep needs.

Psychological capital and alienation among patients with COVID-19 infection: the mediating role of social support

BACKGROUND

COVID-19 infection continues all over the world, causing serious physical and psychological impacts to patients. Patients with COVID-19 infection suffer from various negative emotional experiences such as anxiety, depression, mania, and alienation, which seriously affect their normal life and is detrimental to the prognosis. Our study is aimed to investigate the effect of psychological capital on alienation among patients with COVID-19 and the mediating role of social support in this relationship.

METHODS

The data were collected in China by the convenient sampling. A sample of 259 COVID-19 patients completed the psychological capital, social support and social alienation scale and the structural equation model was adopted to verify the research hypotheses.

RESULTS

Psychological capital was significantly and negatively related to the COVID-19 patients' social alienation (p < .01). And social support partially mediated the correlation between psychological capital and patients' social alienation (p < .01).

CONCLUSION

Psychological capital is critical to predicting COVID-19 patients' social alienation. Social support plays an intermediary role and explains how psychological capital alleviates the sense of social alienation among patients with COVID-19 infection.

The development and effectiveness of web-based psychological capital intervention on the mental well-being of tourism workers during the COVID-19 pandemic

The current COVID-19 situation has forced many tourism businesses to close. Tourism workers have suffered chronic stress, discouragement, despair, and failure to find solutions for their businesses, resulting in deteriorating mental health. A psychological capital intervention (PCI) is therefore deemed necessary as it promotes the mental well-being of tourism workers. This article reports the development of a web-based PCI for the mental well-being of tourism workers and an investigation of its effectiveness using a mixed-methods intervention design. A qualitative approach was used to develop the intervention by conducting interview techniques with 20 tourism entrepreneurs. A content analysis was carried out. The intervention was tested through an experimental research design. The sample comprised 600 tourism workers who undertook a web-based PCI. Data on their mental well-being were collected before the intervention and 1 month afterward and analyzed using ANCOVA. The research revealed that 4 themes are needed for the intervention: having a goal, tolerance of difficulties, inspiration from a role model, and the appropriate way of thinking. An effectiveness examination showed that the web-based PCI improves mental well-being scores significantly. In conclusion, this web-based PCI, which focuses on developing strengths, effectively improves the mental well-being of tourism workers facing difficulties during the COVID-19 pandemic.

Effects of interpersonal sensitivity on depressive symptoms in postgraduate students during the COVID-19 pandemic: Psychological capital and sleep quality as mediators

Background

This study aimed to examine depressive symptoms associated with interpersonal sensitivity, sleep quality, and psychological capital among postgraduate students during static campus management after the COVID-19 pandemic in China.

Methods

Research data were obtained during static campus management (10-19 April 2022) after the reappearance of COVID-19 in cities in eastern China. We collected data through an online questionnaire, and the anonymous self-reported questionnaire included the Patient Health Questionnaire, the interpersonal sensitivity subscale of Symptom Checklist-90, the Psychological Capital Questionnaire, and the Pittsburgh Sleep Quality Index. analysis of variance was performed using t-test and ANOVA. The PROCESS macro was used to determine the relationship between interpersonal sensitivity and depression, together with the independent and serial mediating role of psychological capital and sleep quality.

Results

A total of 2,554 postgraduate students were included in this study. The prevalence of mild, moderate, and severe depressive symptoms was 30.97, 6.58, and 1.45%, respectively. Interpersonal sensitivity was significantly associated with depressive symptoms (direct effect = 0.183, p < 0.001). Between interpersonal sensitivity and depressive symptoms, psychological capital and sleep quality played a single mediating role (indirect effect = 0.136 and 0.100, p < 0.001, respectively) and a chain mediating role together (indirect effect = 0.066, p < 0.001).

Conclusion

Interpersonal sensitivity has a significant influence on depression among Chinese graduate students. Psychological capital and sleep quality may not only independently mediate the relationship between interpersonal sensitivity and depression, but also co-play a chain-mediating role in the pathway from interpersonal sensitivity to depression. Positive psychological interventions and sleep guidance may be beneficial in alleviating depressive symptoms.

Re-creation After Business Failure: A Conceptual Model of the Mediating Role of Psychological Capital

In case of failure, entrepreneurs could endure various financial, psychological, and social costs. These intertwined costs could affect their learning from failure. All individuals do not react in the same way when dealing with adversity. Rather than focusing on (negative) consequences of business failure, we took a more positive approach by using the Conservation of Resources (COR) model theory to build our conceptual model. Psychological capital, which refers to “an individual’s positive psychological state of development characterized by high levels of self-efficacy, optimism, hope, and resilience,” could be considered as a resource to recover from entrepreneurial setbacks. We suggest that a high level of psychological capital plays a mediating role in the relationship between the negative consequences of failure and learning from failure. By learning from this experience, failed entrepreneurs will increase their intention to re-create a venture and pursue their entrepreneurial career. This theoretical research, by building a conceptual model based on resources, offers a more positive approach of entrepreneurial failure and investigates key psychological assets, such as psychological capital, that support the development of entrepreneurial resilience rather than the prevention of business failure.

Psychological Capital and Burnout in Teachers: The Mediating Role of Flourishing

In keeping with the growth in the development of healthy environments in organizational contexts, in recent years, there has also been increasing interest in the identification of personal psychological resources that contribute to improved worker mental health. From this proactive approach, this study examines the mediating role of flourishing in the relationship between psychological capital (PsyCap) and burnout in teachers, a professional group that is particularly prone to suffering from this syndrome. A total of 1379 teachers from pre-school, primary, secondary, and vocational education systems participated in the study. The mediating effect of flourishing was determined via mediation analysis using the PROCESS macro. The results showed that flourishing partially mediates the negative effect of PsyCap on the three symptoms of burnout (emotional exhaustion, depersonalization, and lack of professional accomplishment). These findings indicate that both PsyCap and flourishing may be effective personal resources in reducing teacher burnout. Therefore, in order to prevent burnout, it is advisable to design interventions that combine PsyCap and flourishing.
