The relationship between perceived organizational support and insomnia in Chinese nurses: The Serial multiple mediation analysis

Exploring predictors of insomnia severity in shift workers using machine learning model

Introduction

Insomnia in shift workers has distinctive features due to circadian rhythm disruption caused by reversed or unstable sleep-wake cycle work schedules. While previous studies have primarily focused on a limited number of predictors for insomnia severity in shift workers, there is a need to further explore key predictors, and develop a data-driven prediction model for insomnia in shift workers. This study aims to identify potential predictors of insomnia severity in shift workers using a machine learning (ML) approach and evaluate the accuracy of the resulting prediction model.

Methods

We assessed the predictors of insomnia severity in large samples of individuals (4,572 shift workers and 2,093 non-shift workers). The general linear model with the least absolute shrinkage and selection operator (LASSO) was used to determine an ML-based prediction model. Additional analyses were conducted to assess the interaction effects depending on the shift work schedule.

Results

The ML algorithms identified 41 key predictors from 281 variables: 1 demographic, 7 physical health, 13 job characteristics, and 20 mental health factors. Compared to the non-shift workers, the shift workers showed a stronger association between insomnia severity and five predicting variables: passiveness at work, authoritarian work atmosphere, easiness to wake up, family and interpersonal stress, and medication. The prediction model demonstrated good performance with high accuracy and specificity overall despite a limited F1 score (classification effectiveness) and recall (sensitivity). Specifically, a prediction model for shift workers showed better balance in F1 scores and recall compared to that for non-shift workers.

Discussion

This ML algorithm provides an effective method for identifying key factors that predict insomnia severity in shift workers. Our findings align with the traditional insomnia model while also reflecting the distinctive features of shift work such as workplace conditions. Although the potential for immediate clinical application is limited, this study can serve as guidance for future research in improving a prediction model for shift workers. Constructing comprehensive ML-based prediction models that include our key predictors could be a crucial approach for clinical purposes.

Relationship Between Perceived Organizational Support, Work Well-Being, and Medical Narrative Ability Among Nurses: A Cross-Sectional Multicenter Study

Aims: The purpose of this study was to investigate the relationship between nurses' perceived organizational support, work well-being, and medical narrative ability. Background: With the proposed bio-psycho-social medical model, nurses' medical narrative ability is closely related to patients' health problems and quality of life. Nurses' perceived organizational support and work well-being can improve nurses' empathy and reflection ability to a certain extent and promote patients' rehabilitation. However, the relationship between nurses' perceived organizational support, work well-being, and medical narrative ability is unclear. Methods: A total of 1831 nurses from 8 hospitals in China were surveyed using an online questionnaire that included nurses' sociodemographic, perceived organizational support, work well-being, and medical narrative ability. IBM SPSS 27.0 was used for Pearson's correlation analysis, one-way ANOVA, t-test, and mediation effect analysis using Model 4 in PROCESS (5000 resamples). Results: The total mean score of perceived organizational support (46.68 ± 11.00), work well-being (53.09 ± 10.81), and medical narrative ability (154.48 ± 22.93) among nurses was found to be moderate. The relationship between perceived organizational support, work well-being, and medical narrative ability was significant, with correlation coefficients ranging from 0.348 to 0.685 (p < 0.01). The relationship between perceived organizational support and medical narrative ability is partially mediated by work well-being. The intermediate effect accounted for 52.36% of the total effect. Conclusion: This study found that nurses' work well-being mediated the relationship between perceived organizational support and medical narrative ability. Implications for Nursing Management: This study evaluated nurses' medical narrative ability and explored the relationship between nurses' perceived organizational support, work well-being, and medical narrative ability. The results of this study can help nursing managers and educators to take appropriate measures to intervene nurses' perceived organizational support and work well-being, so as to improve nurses' medical narrative ability and optimize nursing quality.

The mediating role of compassion fatigue between perceived organization support and caring behavior among outpatient nurses in China: a cross-sectional study

BACKGROUND

The caring behaviors of outpatient nurses play a crucial role in improving the quality of care in hospitals. Work resources and personal psychological resources have a significant impact on nurses' caring behavior. Previous research has shown that perceived organizational support and compassion fatigue are linked to nurses' caring behaviors. However, the specific relationship among these variables is less clear in the context of outpatient nurses working in high-stress environments.

METHODS

A convenience sampling method was utilized to recruit 413 outpatient nurses from six tertiary hospitals in Xi'an, China, as research subjects between November 2023 and January 2024. The questionnaires used in the study included a sociodemographic questionnaire, the Perceived Organizational Support Scale, the Chinese version of the Compassion Fatigue Brief Scale, and the Chinese version of the Caring Behavior Scale. Data analysis involved descriptive statistics, Mann-Whitney U test, Kruskal-Wallis H rank-sum test, Spearman correlation analysis, and the PROCESS macro model 4.

RESULTS

A significant negative correlation was observed between the sense of organizational support and compassion fatigue (ρ=-0.547, P < 0.01). Conversely, a significant positive correlation was found between the sense of organizational support and caring behavior (ρ = 0.469, P < 0.01). Moreover, there was a significant negative correlation between compassion fatigue and caring behavior (ρ=-0.641, P < 0.01). Subsequent mediation analysis demonstrated that compassion fatigue partially mediated the relationship between perceived organizational support and caring behaviors. The overall impact of perceived organizational support on caring behavior (β = 0.363) encompasses both its direct influence (β = 0.131) and the indirect impact mediated by compassion fatigue (β = 0.232). The mediating effect accounts for 63.9% of the total effect.

CONCLUSION

Compassion fatigue acts as a partial mediator in the relationship between perceived organizational support and the caring behavior of outpatient nurses. It is essential for nursing managers to effectively manage both the work resources and personal psychological resources of outpatient nurses to improve their caring behaviors in high-stress settings. By improving nurses' organizational support resources, we can reduce the depletion of their personal psychological resources and alleviate negative emotions such as compassion fatigue. This, in turn, can improve nurses' caring behavior and ultimately enhance the overall quality of nursing services in the hospital.

The moderating role of protective factors in shift work disorder and health outcomes: A cross-sectional study

This study investigated whether sleep-specific (e.g. chronotype) and traditional (e.g. resilience) protective factors were associated with reduced shift work disorder (SWD) risk and explored their role as moderators in the relationship between SWD risk and health. Shift workers (n = 126) participated in a cross-sectional study evaluating SWD risk (i.e. low vs. high; SWD-screening Questionnaire), mental health (Patient Health Questionnaire-9; Generalized Anxiety Disorder Questionnaire-7), physical health (Subjective Health Complaints Inventory), sleep (Pittsburgh Sleep Quality Index; Insomnia Severity Index; Epworth Sleepiness Scale), and protective factors (Resilience Scale; Social Provisions Scale; Survey of Perceived Organizational Support; Short Impulsive Behavior Scale; Circadian Type Inventory; reduced-Morningness-Eveningness Questionnaire). Logistic regressions revealed lower sleep languidity was associated with reduced odds (OR = 0.88 [0.79,0.96]) for having high SWD risk. Multiple regression analyses showed in shift workers with high social support or morningness, having high SWD risk was not associated with increased depression symptoms, or insomnia severity and poor sleep quality, respectively. Finally, in those with high or medium levels of perceived organizational support, high SWD risk was not associated with increased gastrointestinal and allergy complaints. Longitudinal research with larger samples is needed to confirm the moderating role of protective factors in the relationship between SWD risk and health.

The relationship between organizational support, professional quality of life, decent work, and professional well-being among nurses: a cross-sectional study

BACKGROUND

Nurses often face challenges such as inadequate welfare protection, injustice, and workplace adversity including violence, bullying, and sexual harassment. In this context, providing sufficient support to nurses is crucial for the promotion of their professional well-being. This study examines the direct and indirect effects of perceived organizational support on nurses' well-being, particularly highlighting the mediating roles of professional quality of life and the perception of decent work.

METHODS

A cross-sectional survey design was employed in this study. Convenience sampling was used to survey 792 nurses from five tertiary A-grade hospitals in Shanxi Province in January 2024. Data collection tools included a custom demographic survey, the Perceived Organizational Support Scale, Professional Quality of Life Scale, Decent Work Perception Scale, and Nurse Occupational Well-being Questionnaire. Descriptive statistics, correlation analysis, and mediation effect analyses were performed.

RESULTS

The findings demonstrate that perceived organizational support has a direct impact on nurses' occupational well-being (β = 0.323, p < 0.001). Additionally, professional quality of life and the perception of decent work play chain mediating roles between perceived organizational support and nurses' well-being (β = 0.019, BootLLCI = 0.010, BootULCI = 0.030).

CONCLUSIONS

This study highlighted the importance of organizational support in enhancing nurses' well-being. Professional quality of life and decent work were key mediators. Healthcare institutions should prioritize support measures to improve nurses' well-being. Future research should explore additional mediators and mechanisms to develop effective strategies for nursing policymakers and administrators.

Status and influencing factors of work stress among nurse managers in western China: a cross-sectional survey study

AIMS

Due to the nature of their work, nurses are more prone to experiencing psychological consequences than other healthcare workers. However, evidence on the emotional burden of nurse managers in China is limited. Furthermore, perceived organizational support has been approved that can affect mental health outcomes. Therefore, this study aimed to investigate the status quo and influencing factors of nurse managers' work stress, and their possible relationship with perceived organizational support, which could further provide more countermeasures to safeguard their health.

METHODS

A cross-sectional online survey of 21 secondary and tertiary hospitals was conducted in a city in Sichuan province, Southwest China, using a convenience sampling method between October and November 2022. Data were collected using the general information questionnaire, the Chinese version of the Stress Overload Scale (SOS) and the perceived Organizational Support Scale (POSS). SPSS 23.0 was applied to analyze the data.

RESULTS

In total, 380 participants completed the survey. The median scores (interquartile range [IQR]) for SOS and POSS were 60.50 (50.00, 70.75) and 51.00 (44.00, 55.00), respectively. The work stress of the nurse managers was negatively correlated with perceived organizational support (P < 0.01). Multiple linear regression analysis showed that age older than 40 years, from secondary hospitals, working in emergency or pediatric wards, and professional qualification of supervisor nurse or deputy supervisor nurse, and the scores of POSS less than 51 significantly influenced the work stress of the nurse managers.

CONCLUSIONS

Our study shows that nurse managers are more prone to work stress, and organizational support can effectively reduce this stress. Governments and hospital administrators should pay more attention to providing comprehensive strategies based on various risk factors to protect and promote psychological health.

Registered nurses' psychological capital: A scoping review

AIMS

The aim was to examine the extent and scope of empirical research concerning registered nurses' psychological capital.

BACKGROUND

In a time of global nursing shortage, identifying variables that could positively contribute to the retention of the nursing workforce is essential. Prior research has shown that psychological capital correlates positively with employees' better performance and well-being.

DESIGN

A scoping review.

DATA SOURCES

A systematic literature search was conducted in the following databases: PubMed, CINAHL, PsycINFO, Web of Science and Scopus covering the period from 1 January 2005 to 7 May 2023.

REVIEW METHODS

The JBI methodological guidance for scoping reviews was followed. The results were summarized narratively.

RESULTS

A total of 111 studies reported in 114 peer-reviewed articles were included. Studies were carried out across 20 countries, with the majority from China (45), Australia (nine), Pakistan (nine), Canada (eight), South Korea (eight) and the United States (eight). A positive correlation was found between registered nurses' psychological capital and desirable work-related outcomes, such as work engagement, commitment and retention intention.

CONCLUSION

A comprehensive overview of research evidence suggests that psychological capital is associated with many positive work-related outcomes and might therefore be a valuable resource for reducing nurse turnover.
