Specific Salivary Neuropeptides Shift Synchronously during Acute Stress in Fire Recruits

Once thought of as an immune-privileged site, we now know that the nervous system communicates in a bidirectional manner with the immune system via the neuroimmune axis. Neuropeptides constitute a component of this axis, playing critical roles in the brain and periphery. The function of salivary neuropeptides in the acute stress response is not well understood. The purpose of this study is to investigate salivary neuropeptide levels during acute stress. Salivary samples were collected from fire recruits engaged in a stress training exercise previously shown to induce acute stress, at three separate timepoints during the exercise and levels of oxytocin, neurotensin, Substance P, α-MSH, and β-Endorphin were measured using the Human Neuropeptide 5-Plex Custom Assay Eve Technologies. All neuropeptides increased throughout the acute stress simulation and during the recovery phase. Exploratory factor analysis (EFA) identified one factor contributing to baseline values across five neuropeptides and Pairwise Pearson Correlation Coefficient analysis showed positive correlations >0.9 for almost all neuropeptide combinations at the pre-stress timepoint. Further analysis identified negative and positive correlations between past-life trauma and self-assessed hardiness, respectively. Calculated neuropeptide scores showed an overall positive correlation to self-assessed hardiness. Altogether, our results suggest that salivary neuropeptides increase synchronously during acute stress and higher levels correlate with an increase in self-assessed hardiness. Further study is required to determine if interventions designed to enhance neuropeptide activity can increase stress resilience, especially in high-stress occupations such as firefighting.

Fostering organisational commitment: a resilience framework for private-sector organisations in South Africa

Introduction

Organisations worldwide encounter three significant and challenging issues related to talent management: intense competition for skilled employees, elevated rates of employee attrition, and the ongoing struggle to attract top-tier talent. This research focused on investigating the interconnected dynamics among factors associated with employee retention, including organisational commitment, job embeddedness, and hardiness, in conjunction with resilience-related behaviours such as resilience and career adaptability.

Methods

A cross-sectional survey design was used to gather quantitative data from a convenience sample of employees within the private sector in South Africa (N = 293). The self-assessments of the participants were assessed using a range of well-established and validated instruments. Correlation and regression analyses, followed by structural equation modelling, were utilised to construct a resilience framework designed specifically for private sector organisations in South Africa.

Results

The results reveal significant associations between organisational commitment, job embeddedness, and hardiness (as retention-related attributes) and resilience and career adaptability (as resilience-related behavioural capacities). These relationships served as the basis for the development of a resilience framework for employees in South African private organisations.

Discussion

In South African private-sector organisations, talent retention is crucial due to a talent shortage. The study found that employees have a strong emotional attachment to their organisations, are highly aligned with their jobs and communities, and display resilience. Organisational commitment, job embeddedness, and hardiness are key factors in reducing turnover, forming an effective retention strategy. This research contributes to the development of a resilience framework for South African private sector organisations.

Hardiness and Zoom Fatigue on Nursing Students: A Cross-Sectional Study in Indonesia During Online Learning

Introduction

The Covid-19 pandemic caused a change in learning methods to online learning. Zoom fatigue is a problem that many students experience during online learning. Zoom fatigue has an impact on physical and psychological problems so that it disrupts the online learning process. Hardiness is needed by students in order to adapt to online learning.

Aim

The purpose of this study was to determine the relationship between hardiness and zoom fatigue in nursing students at Universitas Padjadjaran.

Methods

This study used a quantitative approach with a cross-sectional study design. The sample technique used total sampling. Respondents were 480 nursing students at Universitas Padjadjaran. The research instrument used the Zoom Exhaustion & Fatigue Scale questionnaire and the Hardiness Instrument for the Online Learning.

Results

This study shows that almost half of the respondents have a medium hardiness level category (45%) and a zoom level of medium fatigue category (46.67%). The results of the analysis show that there is a significant negative relationship between hardiness and zoom fatigue in nursing students at Universitas Padjadjaran. The higher the student's hardiness level, the lower the student's zoom fatigue level. High hardiness can increase focus during the learning process, increase student participation, and reduce stress and fatigue in students during online learning.

Conclusion

Lecturers and students need to collaborate to improve the learning process and repeat mental health problems during online learning. This data forms the basis for university and school nurses in providing interventions for nursing students to reduce the problem of zoom fatigue.

Cognitive flexibility and psychological hardiness: examining the mediating role of positive humor styles and happiness in teachers

In this study, the mediating role of positive humor styles and happiness in the relationship between cognitive flexibility and psychological hardiness was investigated. The participants in the study, which was conducted based on a correlational design, one of the quantitative research methods, consisted of 613 volunteer teachers (322 women, 291 men) employed in various schools and institutions affiliated to the Ministry of National Education in Turkey. The study data were obtained through the Cognitive Flexibility Scale, the Psychological Hardiness Scale, the Humor Styles Questionnaire, and the Oxford Happiness Questionnaire Short-Form. Correlation analysis, structural equation modeling and bootstrapping were used for the analysis of the data. The results obtained from the mediation test showed that cognitive flexibility positively predicted psychological hardiness, and that positive humor styles and happiness were partial mediating variables in this relationship. The findings obtained in the research were discussed in the light of the related literature and recommendations were presented.

Hardiness moderates the effects of COVID-19 stress on anxiety and depression

The COVID-19 pandemic has led to sharp increases in mental health problems around the world, most notably in anxiety and depression. The present study examines hardiness and age as potential protective factors against the mental health effects of COVID-related stress. A sample of Canadians balanced across age and gender, completed an online survey including measures of COVID related stressors, hardiness, depression, and anxiety, along with age, gender, and other demographics. Conditional PROCESS analysis showed that COVID stressors led to significant increases in anxiety and depression. Hardiness moderated these relations, with those high in hardiness showing less anxiety and depression. Age was negatively related to anxiety and depression, with highest levels observed among the younger respondents. At the same time, a moderating effect of age was found with respect to depression, with older people showing sharper increases in depression as COVID-related stress goes up. Gender was not a significant factor in any of these relations, meaning that the results apply equally well to both women and men. This study provides evidence that younger people who are also low in hardiness are most vulnerable to developing anxiety and depression while under COVID stress, and so would likely benefit from preventive intervention strategies. While anxiety and depression symptoms are highest among the young, older age groups appear more vulnerable to increasing rates of depression symptoms related to COVID stress. Clinicians and practitioners should thus be especially vigilant for COVID related increases in depression among older people, and those low in psychological hardiness.

Interventions to foster resilience in nursing staff: A systematic review and meta-analyses of pre-pandemic evidence

BACKGROUND

Given the chronic work-related stressors experienced by nursing staff in today's healthcare systems, international evidence suggests an elevated risk of developing stress-related mental symptoms. Therefore, identifying effective methods to foster resilience (i.e., maintenance or fast recovery of mental health despite stressor exposure) seems crucial. To date, little is known about the efficacy of these interventions in nurses.

OBJECTIVE

This systematic review aimed at summarizing the evidence on the pre-pandemic efficacy of psychological interventions to foster resilience, to improve mental symptoms and well-being as well as to promote resilience factors in nurses. Based on training programs with evidence for positive effects on resilience and mental health in meta-analyses, we aimed at identifying important and helpful intervention techniques.

DESIGN

Systematic review and meta-analyses based on a Cochrane review on pre-pandemic resilience interventions in healthcare professionals.

DATA SOURCES

MEDLINE, Embase, CENTRAL and 11 other databases were searched until June 2020 to identify eligible randomized controlled trials. Trial registers, reference lists and contact with authors were additional sources.

REVIEW METHODS

Two reviewers independently assessed study eligibility and extracted data. The Cochrane risk of bias assessment tool was used to evaluate the risk of bias of included studies. We conducted random-effects pairwise meta-analyses for five primary outcomes, including resilience. The intervention contents and techniques were narratively synthesized.

RESULTS

Of 39,794 records retrieved, 24 studies were included in the review (N = 1879 randomized participants), 17 in meta-analyses (n = 1020 participants). At post-intervention, we found very-low certainty evidence of moderate effects in favor of resilience training for resilience (standardized mean difference [SMD] 0.39; 95% CI [confidence interval] 0.12-0.66) and well-being (SMD 0.44; 95% CI 0.15-0.72), while there was no evidence of effects on symptoms of anxiety, depression and stress. The improvement of well-being was sustained in the short-term (≤3 months), with additional delayed benefits for anxiety and stress. There was no evidence of effects at later follow-ups, with the caveat of only three available studies. Among nine programs with evidence of positive moderate effect sizes, intervention contents included mindfulness and relaxation, psychoeducation, emotion regulation, cognitive strategies, problem-solving and the strengthening of internal and external resources.

CONCLUSIONS

Given the chronic stressor exposure in nursing staff, our findings may guide both the design and implementation of nurse-directed resilience interventions. To improve the certainty of evidence, more rigorous high-quality research using improved study designs (e.g., larger sample sizes, longer follow-up periods) is urgently needed.

Emergency Stress, Hardiness, Coping Strategies and Burnout in Health Care and Emergency Response Workers During the COVID-19 Pandemic

Objective

Stress is a growing problem in the general population, but most especially for workers responding to the COVID-19 crisis. The present study examines stress and Burnout in Health Care workers and Emergency Responders during the third COVID wave in Italy. In addition, we explore the value of psychological Hardiness and positive coping strategies as protective factors against the ill-effects of stress.

Methods

Over a 5-month period in 2021, surveys were administered across all Italian regions to several groups including Health Care workers (N = 220), Emergency Responders (firefighters, civil protection, ambulance personnel; N = 121), volunteer Italian Red Cross workers (N = 328), and a comparison group (N = 400) drawn from the General Population of Italy.

Results

Results showed that among the groups, Health Care workers had the highest levels of Emergency Stress, while the Red Cross volunteers had relatively lower stress levels. Hardiness and positive coping levels were highest among Red Cross workers, and lowest in the General Population sample. The biggest impact on Burnout was seen among health care workers, especially on Emotional Exhaustion and Depersonalization. Multiple regression results showed that Hardiness operates as a moderator of the effects of Emergency Stress on Emotional Exhaustion and Depersonalization aspects of Burnout, while problem focused coping and Stopping Negative Thoughts-Emotions also showed moderating effects.

Conclusion

These results suggest that Health Care workers and Emergency Responders would benefit from additional training in hardiness and positive coping skills.
