Factors Associated With Work Engagement of Nurses During the Fifth Wave of the COVID-19 Pandemic in Japan: Web-Based Cross-Sectional Study.

BACKGROUND: The COVID-19 pandemic has brought to light the prevalence of mental health issues among nurses. Work engagement (WE) is a concept that describes work-related positive psychological states and is of importance within mental health measures. There is, however, a lack of research on factors associated with the WE of nurses during the COVID-19 pandemic. OBJECTIVE: We aimed to determine which factors are associated with WE among nurses during the COVID-19 pandemic using the job demands-resources (JD-R) model as a framework. METHODS: A web-based cross-sectional survey was conducted among nurses working in acute care and psychiatric institutions in the prefectures of Chiba and Tokyo in Japan. The survey period occurred between August 8 and September 30, 2021, during a time when the number of patients with a positive COVID-19 infection increased. The 3-item version of the Utrecht Work Engagement Scale (UWES-3) was used to measure WE. Factors such as age, gender, years of experience, affiliated ward, COVID-19-related stress, financial rewards from the government and hospital, encouragement from the government and patients, and workplace social capital were assessed. A total of 187 participants were included in the final analysis. Multiple regression analysis was performed to examine the factors related to WE. Partial regression coefficients (B), 95% CI, and P values were calculated. RESULTS: The mean overall score for the UWES-3 was 3.19 (SD 1.21). Factors negatively associated with UWES-3 were COVID-19-related stress on work motivation and escape behavior (Β -0.16, 95% CI -0.24 to -0.090; P<.001), and factors positively associated with UWES-3 were affiliation of intensive care units (Β 0.76, 95% CI 0.020-1.50; P=.045) and financial rewards from the government and hospital (Β 0.40, 95% CI 0.040-0.76; P=.03). CONCLUSIONS: This study examined factors related to WE among nurses during the COVID-19 pandemic using the JD-R model. When compared with findings from previous studies, our results suggest that nurses' WE was lower than before the COVID-19 pandemic. Negative motivation and escape behaviors related to COVID-19 were negatively associated with WE, while there were positive associations with financial rewards from the government and hospital and affiliation with an intensive care unit. Further research into larger populations is needed to confirm these findings.

Relationships between sleep efficiency and lifestyle evaluated by objective sleep assessment: SLeep Epidemiology Project at University of Tsukuba.

Objectively measured sleep efficiency has recently been shown to be associated with health problems. Although several factors have previously been reported to be associated with sleep efficiency, most of these studies were conducted on older or younger adults, and the factors associated with sleep efficiency in healthy workers remain unknown. The aim of this study was to investigate the relationship between sleep efficiency and lifestyle factors using sleep measurement data recorded by an activity meter worn by workers. In total, 693 workers (male, 43.6%; mean age, 42.7 ± 11.3 years) were recruited from five offices in 2017. Sleep was measured over the period of 1 week by actigraphy. Workers' attributes, lifestyle habits, and occupational stress were identified using a questionnaire, and the association of sleep efficiency with lifestyle, occupational stress, and attributes was explored by logistic regression analysis. A logistic regression analysis using attributes and occupational stress as adjustment variables revealed that "longer sleeping hours on weekends than on weekdays" [odds ratios (OR), 0.66; 95% confidence interval (CI), 0.47-0.94], "water ingestion at bedtime" [OR, 2.09; 95% CI, 1.28-3.41], and "smartphone use at bedtime" [OR, 1.90; 95% CI, 1.28-2.83] were associated with decreased sleep efficiency. This study found that lifestyle habits were associated with sleep efficiency among workers. It is necessary to verify whether intervention in these lifestyle habits would contribute to the improvement of sleep efficiency in future studies.

Differences in psychological distress between managers and non-managers in female workers: a cross-sectional study in Tsukuba Science City, Japan.

The Japanese government has made efforts towards the advancement of women into society; thereby, the proportion of female managers has been increasing. Recent reports have shown that managers tend to be in poor health condition. However, little research has been conducted to examine the psychological health of female managers. Therefore, the aim of our study was to reveal the difference of psychological distress by occupational position in female workers with focus on occupational stress. A cross-sectional survey was conducted in 2017 via an anonymous, self-administered questionnaire distributed to workers in Tsukuba City, Japan. Student unpaired t test was used to compare occupational stress and psychological distress by occupational position. Binomial logistic regressions were used to analyze factors that affect psychological distress separately in managers and non-managers. A total of 1543 women (168 managers, 1375 non-managers) were analyzed. Managers showed higher occupational stress but lower psychological distress than non-managers. Problems in interpersonal relationships was positively associated with psychological distress, whereas occupation as a researcher/academic was negatively associated with psychological distress in managers. Mental workload and problems in interpersonal relationships were positively associated with psychological distress, whereas reward from work and support were negatively associated with psychological distress in non-managers. Managers and non-managers both showed an association between psychological distress and problems of interpersonal relationships. Non-managers might have higher psychological distress due to lower reward from work. It is important to increase reward from work and to develop female workers' interpersonal skills in order to reduce the psychological distress of female workers.

[Study of the relationship between incidence of sick leave due to mental health failure and work rules about sick leave].

OBJECTIVES: This study examined the relationships among the support system for return to work, work rules about sick leave, and incidence of sick leave due to mental health failure. METHODS: A questionnaire was distributed to 150 workplaces with a history of use of the occupational health promotion center of a certain prefecture. The questionnaire asked about the number and duration of sick leaves due to mental health failure, the support system for return to work, and work rules about sick leave. RESULTS: A significant correlation between the number of permanent staff and maximum period of sick leave was found (r=0.489, p<0.001), as well as a significant correlation between the number of permanent staff and the period of monetary compensation during sick leave (r=0.315, p=0.031). In addition, in 9 workplaces with more than 1,000 permanent staff, a significant correlation between the period of monetary compensation period during sick leave and incidence of sick leave was found (r=0.670, p=0.048), as well as a significant correlation between the period of monetary compensation during sick leave and the average length of sick leave (r=0.866, p<0.001). CONCLUSIONS: The results of this study suggest the possibility that monetary compensation is associated with the duration of sick leave due to mental health failure. Hereafter, to construct a support system for mental health, consideration of the effect of monetary compensation appears to be required.

The effect of stress-related factors on mental health status among resident doctors in Japan.

OBJECTIVES: This study was designed to investigate how the interaction between the ability of medical residents (doctors in postgraduate training) to cope with stress and their working conditions might affect their level of job-related stress. METHODS: A self-administered questionnaire was distributed to 549 first-year medical residents at 38 postgraduate education hospitals in Japan, 1-2 months after the start of clinical training. The questionnaires contained the 29-item Sense of Coherence (SOC) Scale, the Brief Scales for Job Stress (BSJS), the 12-item General Health Questionnaire (GHQ-12) and questions on basic conditions such as working hours. Sense of coherence is an important concept from the viewpoint of salutogenesis theory and influences stress recognition style. People with a strong SOC have a high ability to cope with stress. RESULTS: The mean +/- standard deviation (SD) score on the SOC Scale was 134.5 +/- 20.5. All participants were classified into three groups according to their SOC Scale scores. Although the objective working conditions of the three groups were statistically similar, the group with the weakest SOC Scale score showed poorer mental health status (p < 0.05) and scored lower for 'reward from work' compared with the groups with stronger SOC scores (p < 0.05). The weaker SOC group also scored higher for 'mental workload' and 'problems in personal relationships' than the other two groups (p < 0.05). Moreover, the weak SOC group scored less for 'support from colleagues and superiors' than the strong SOC group (p < 0.05). A stepwise multiple regression analysis for GHQ-12 score was conducted (R(2) = 0.45). 'Sleep time', 'workload', 'mental workload' and 'problems in personal relationships' were positively correlated with GHQ-12 scores. 'Reward from work' was negatively correlated with GHQ-12 scores. CONCLUSIONS: Residents' mental health was associated not only with working conditions, but also with their attitudes towards those working conditions. Enhancing residents' sense of 'reward from work' might be important in reducing their reactions to stress.

Roll-over detection and sleep quality measurement using a wearable sensor.

Mental health management in the workplace has attracted increasing attention in recent years. As sleep is an essential physiological function that is strongly related to mental condition, easy and daily sleep management is considered essential for maintaining good mental health. In this paper, we detected roll-over movements during sleep using a wearable armband-shaped sensor, SenseWear Pro2 Armband. We then classified sleep depth into two stages, light sleep and deep sleep, based on roll-over frequency. We also propose a new index designated the Sleep Quality Score (SQS). Finally, we performed long-term measurement and compared SQS in healthy people and patients with major depression disorder.
