Research on the mechanism of academic stress on occupational burnout in Chinese universities.

In recent years, with the unremitting advancement of higher education reform, academics have been experiencing stress associated with conducting scientific research. In this study focusing on university teachers in China, we adopted a stepwise regression method and reviewed related literature to construct a mechanism of academic stress and occupational burnout. Specifically, we tested job satisfaction and relative deprivation as mediating and moderating variables and conducted empirical research on 1239 teachers from 15 universities in eastern, central, and western China. Our findings show that: (1) academic stress has a significant positive effect on occupational burnout; (2) job satisfaction has a partial role as the intermediary agent between academic stress and occupational burnout; and (3) relative deprivation positively moderates the relationship between academic stress and job satisfaction, indicating that teachers in universities and colleges are also affected by relative deprivation and the perception of inequity. These findings have significant value in the management of higher education and academic research.

Psychosocial strain and coping of Finnish working mothers during the COVID-19 lockdown: a job demand-control approach.

Introduction: In March 2020 many countries around the world, including Finland, implemented lockdown measures to mitigate the unprecedented impacts of the coronavirus infectious disease (COVID-19) on public health. As a result, school and daycare settings closed indefinitely and working from home became the new normal for a big part of the workforce, which came with increased homeschooling and childcare responsibility for mothers. Methods: In this article we present the findings from maternal responses to open ended questions on psychosocial well-being, and experiences of combining work, family life and homeschooling during the COVID-19 national lockdown in Finland in March-May 2020. Working mothers' responses (n = 72) were analyzed through the lens of Karasek's job demand-control model, focusing on how the mothers experienced the demands of their life during the lockdown, and how they saw their possibilities to control the situation. Results: The findings indicated important variation in the level of experienced demand and control and associated compensatory factors during the COVID-19 lockdown across different subgroups of working mothers. Discussion: The findings have implications for understanding strain and plausible supports among working mothers during the COVID-19 lockdown as well as in the face of acute adversity including the next possible public health crisis.

Formulations of Job Strain and Psychological Distress: A Four-year Longitudinal Study in Japan.

Background: Different job strain formulations based on the Job Demand-Control model have been developed. This study evaluated longitudinal associations between job strain and psychological distress and whether associations were influenced by six formulations of job strain, including quadrant (original and simplified), subtraction, quotient, logarithm quotient, and quartile based on quotient, in randomly selected Japanese workers. Methods: Data were from waves I and II of the Survey of Midlife in Japan (MIDJA), with a 4-year follow-up period. The study sample consisted of 412 participants working at baseline and had complete data on variables of interest. Associations between job strain at baseline and psychological distress at follow-up were assessed via multivariable linear regression, and results were expressed as ß coefficients and 95% confidence intervals including R2 and Akaike information criterion (AIC) evaluation. Results: Crude models revealed that job strain formulations explained 6.93-10.30% of variance. The AIC ranged from 1475.87 to 1489.12. After accounting for sociodemographic and behavioral factors and psychological distress at baseline, fully-adjusted models indicated significant associations between all job strain formulations at baseline and psychological distress at follow-up: original quadrant (ß: 1.16, 95% CI: 0.12, 2.21), simplified quadrant (ß: 1.01, 95% CI: 0.18, 1.85), subtraction (ß: 0.39, 95% CI: 0.09, 0.70), quotient (ß: 0.37, 95% CI: 0.08, 0.67), logarithm quotient (ß: 0.42, 95% CI: 0.12, 0.72), and quartile based on quotient (ß: 1.22, 95% CI: 0.36, 2.08). Conclusion: Six job strain formulations showed robust predictive power regarding psychological distress over 4 years among Japanese workers.

Work engagement among older workers: a systematic review.

OBJECTIVES: Given current labor force conditions, including population aging, keeping older workers engaged in work and motivated is important. Aging may alter the effects that psychological and environmental factors have on work engagement. We conducted a systematic review to understand the features of work engagement among older workers. METHODS: A systematic search was conducted in July 2022 using 4 databases. The review included relevant articles that focused on participants aged 40 years and older. RESULTS: Fifty articles were selected for our review, which were grouped into 5 categories: (1) studies examining the relationship between chronological age and work engagement, (2) studies investigating the moderating effects of age on the relationship between job-related psychological factors and work environment factors and work engagement, (3) studies comparing the relationship of job-related psychological factors and work environment factors with work engagement across different age groups, (4) studies exploring the relationship between work engagement and retirement intentions or continued employment beyond retirement age, and (5) other studies discussing work engagement in the context of older workers. Most articles focused on workers in Europe and the United States and used observational study designs. CONCLUSIONS: Work engagement increases with age, and is mainly mediated by increased emotional regulation. In addition, age moderates the relationships between various job-related psychological and work-environmental factors and work engagement. Work engagement is associated with working beyond retirement age. Organizations should understand the characteristics of work engagement among older workers and make age-conscious efforts to support them in adapting to social changes.

The Effects of Workplace Stressors on Dietary Patterns among Workers at a Private Hospital in Recôncavo of Bahia, Brazil: A Longitudinal Study before and during the COVID-19 Pandemic.

Working in a hospital environment is known for presenting unhealthy features that affect the workers' health-features which have currently been intensified due to the COVID-19 pandemic. Hence, this longitudinal study aimed to ascertain the level of job stress before and during the COVID-19 pandemic, how this changed, and its association with the dietary patterns of hospital workers. Data on sociodemographic, occupational, lifestyle, health, anthropometric, dietetic, and occupational stress were collected before and during the pandemic from 218 workers at a private hospital in the Recôncavo of Bahia, Brazil. McNemar's chi-square test was used for comparison purposes, Exploratory Factor Analysis to identify dietary patterns, and Generalized Estimating Equations to evaluate the interested associations. During the pandemic, participants reported increased occupational stress, shift work, and weekly workloads, compared with before the pandemic. Additionally, three dietary patterns were identified before and during the pandemic. No association was observed between changes in occupational stress and dietary pattens. However, COVID-19 infection was related to changes in pattern A (0.647, IC95%0.044;1.241, p = 0.036) and the amount of shift work related to changes in pattern B, (0.612, IC95%0.016;1.207, p = 0.044). These findings support calls to strengthen labour policies to ensure adequate working conditions for hospital workers in the pandemic context.

Psychosocial and biological predictors of resident physician burnout.

BACKGROUND: A high proportion of health professionals in training suffer from work-related stress and may develop a burnout syndrome. OBJECTIVES: To study the incidence of burnout after the first year of residency in a teaching hospital and to identify baseline psychological, psychosocial work conditions, and biological risk factors. METHODOLOGY: We assessed the following in a prospective cohort of residents at baseline (first month residence) and after 1 year: background factors (socio-demographics, psychiatric history), perceived stress score (Perceived Stress Scale), Maslach Burnout Inventory score, and psychosocial factors (Job Content Questionnaire). Blood samples were obtained to study serum cortisol, IL-6, and TNF-α concentrations. The cumulative incidence was modelled by multivariate log-binomial regression analysis. RESULTS: We included 71 participants with a female majority (64.8%), age 26.4 (2.65) years, psychiatric history in 20%, and burnout in 13%. Among those without burnout initially (N = 59), it had developed by 1 year in 22% of residents. Increased job demand (RR = 1.259, 95%CI = 1.019-1.556, p = 0.033) and decreased cortisol levels (RR = 0.877, 95%CI = 0.778-0.989, p = 0.032) predicted burnout after 1 year of residency among medical trainees. CONCLUSION: Burnout syndrome develops in 22% of residents by 1 year of training and can be predicted by increased work demands and decreased cortisol levels.

Job demands and job control among occupational therapists in public sector in Finland.

BACKGROUND: Although health care professionals' increased job demands and strain have generated much public debate in recent years, the way in which occupational therapists' job strain has developed remains unknown. OBJECTIVE: To examine how Finnish occupational therapists working in municipalities experienced job demands and control in 2014-2018 compared with physiotherapists and registered nurses. MATERIAL AND METHODS: Occupational therapists (OT, n = 107), physiotherapists (PT, n = 331) and registered nurses (RN, n = 1389) responded to repeated surveys in the Finnish Public Sector Study in 2014-2018. We used the Job Content Questionnaire and analyzed the data using repeated measures analysis of variance and multiple linear regression with generalized estimating equations to identify the trends and differences. RESULTS: More OTs had lower job demands and higher job control than PTs and RNs in each year of study. These differences were statistically significant. Most OTs had low job strain. The changes in job control and job demands of participants in different years were not statistically significant. CONCLUSIONS: The OTs consistently experienced low job strain as compared to the PTs and RNs. Developing good practices in OT's work may be beneficial for improving employee health and well-being and high-quality client care.

Work-related factors on mental health among migrant factory workers in china: Application of the Demand-Control and Effort-Reward Imbalance Model.

Mental health problems are prevalent among migrant workers in China. The present study examined the prevalence of mental health problems (depression, anxiety and suicidal ideation) among migrant workers in China, and identified the work-related factors associated with their mental health problems based on the Demand-Control and Effort-Reward Imbalance Model. A total of 807 migrant workers were recruited from three factories in Shenzhen using stratified randomized sampling. The prevalence of moderate-to-severe anxiety, mild-to-severe depression and suicidal ideation in the past year was 17.8%, 60.3% and 4.8% respectively. Results from stepwise regression analyses reported that role conflict and effort were risk factors, whereas utilization of job skills and reward were protective factors for anxiety and depression. Social support was also associated with lower level of depression. Effort was the only factor associated with suicidal ideation in the stepwise analysis. Interventions to improve their mental health are warranted and they should work to reduce their role conflict, improve effort-reward balance, promote utilization of skills and increase social support.

The Demand-Control Model and Pupils' Aggressive Behaviour towards Teachers: A Follow-Up Study.

PURPOSE: Pupils' aggressive behaviour towards teachers is a common phenomenon in schools across different countries. The purpose of this study is to test hypotheses that are central to the Job Demand-Control model as risk factors for pupils' aggressive behaviour towards teachers. METHOD: Questionnaire data were collected in 2018 and 2019 from teachers at 94 public schools in Denmark. In total, 1198 teachers participated in both rounds. Demands and social support at work were measured in 2018, and pupils' aggressive behaviour was measured in 2019. The analyses were performed using multivariate logistic regression analysis. RESULTS: Teachers were often exposed to pupils' aggressive behaviour during their work. High emotional work demands and low control were associated with increased risk of pupils' aggressive behaviour. No mitigating effect of high control was found on the association between emotional demands and risk for pupils' aggressive behaviour towards teachers. CONCLUSION: High emotional demands were strongly associated with the aggressive behaviour of pupils towards teachers. Job control over own work situation was not enough to lower the risk of aggressive behaviour under conditions in which teachers experience high emotional demands. Based on these results, we recommend that supervisors carefully balance teachers' emotional demands to their resources.

Depression symptoms mediate the association between workplace stress and interleukin 6 in women, but not men: The Whitehall II study.

Workplace stress and depression are positively related with inflammation, and each other. Low-grade inflammation and concurrent high levels of workplace stress or depression has been related with future morbidity. The potential pathway between constructs however, remains elusive. For the first time, this study explored the concurrent relationship between workplace stress, depressive symptomology and low-grade inflammation, and considered the role of gender in these relationships. Data from the Whitehall II cohort study (N â€‹= â€‹2528, Mage â€‹= â€‹57.01, 23.7% females) provided measures of workplace stress (job demand-control; JDC), depressive symptomology (Centre for Epidemiological Studies Depression scale; CES-D) and circulating inflammatory markers, interleukin-6 (IL-6) and C-reactive protein (CRP) collected on the same day from a single time point. Females had higher workplace stress, depressive symptoms and lower serum IL-6 concentrations. For males, higher workplace stress was associated with higher depressive symptoms. For females, higher depressive symptoms were related with elevated IL-6 levels, and both higher workplace stress and IL-6 levels were associated with higher depressive symptoms. Higher depressive symptoms were related with higher CRP levels in men only. Higher depressive symptoms statistically mediated the relationship between higher workplace stress and IL-6 levels in females only, b â€‹= â€‹0.016, CI [0.002, 0.039]. Females in this large cohort had higher levels of job strain, depression and lower IL-6 concentrations than males. In females, higher depressive symptoms were associated with higher serum IL-6 levels and workplace stress was not. Considered together, these findings suggest that low job control may be more apparent in females than males, but it is primarily negative affect that drives the positive relationship between work stress and serum IL-6 concentrations in females. Replicating the current design with a suitably proximal follow-up is required to determine if the associations identified are causal.

Measuring job stress in transportation workers: psychometric properties, convergent validity and reliability of the ERI and JCQ among professional drivers.

BACKGROUND: The accumulated evidence has shown how professional drivers are, in psychosocial terms, among the most vulnerable workforces, and how their crashes (some of them preceded by stressful working conditions) constitute both an occupational and public health concern. However, there is a clear lack of validated tools for measuring stress and other key hazardous issues affecting transport workers, and most of the existing ones, frequently generic, do not fully consider the specific features that properly describe the work environment of professional driving. This study assessed the psychometric properties, convergent validity and consistency of two measures used for researching occupational stress among professional drivers: the Siegrist's ERI (Effort-Reward Imbalance Inventory) and Karasek's JCQ (Job Content Questionnaire). METHODS: We examined the data collected from 726 Spanish professional drivers. Analyses were performed using Structural Equation Models, thus obtaining basic psychometric properties of both measures and an optimized structure for the instruments, in addition to testing their convergent validity. RESULTS: The results suggest that the abbreviated versions of ERI (10 items) and JCQ (20 items) have clear dimensional structures, high factorial weights, internal consistency and an improved fit to the task's dynamics and hazards, commonly faced by of professional drivers; a short set of items with low psychometrical adjustment was excluded, and the root structure of the questionnaires was kept. CONCLUSIONS: This study supports the value and reliability of ERI-10 and JCQ-20 for measuring job stress among professional drivers. Also, there is a high consistency between both measures of stress, even though they belong to different theoretical conceptions of the phenomenon. In practical settings, these instruments can be useful for occupational researchers and practitioners studying stress-related issues from the perspective of human factors.

The Demand-Control Model as a Predictor of Depressive Symptoms-Interaction and Differential Subscale Effects: Prospective Analyses of 2212 German Employees.

Testing assumptions of the widely used demand-control (DC) model in occupational psychosocial epidemiology, we investigated (a) interaction, i.e., whether the combined effect of low job control and high psychological demands on depressive symptoms was stronger than the sum of their single effects (i.e., superadditivity) and (b) whether subscales of psychological demands and job control had similar associations with depressive symptoms. Logistic longitudinal regression analyses of the 5-year cohort of the German Study of Mental Health at Work (S-MGA) 2011/12-2017 of 2212 employees were conducted. The observed combined effect of low job control and high psychological demands on depressive symptoms did not indicate interaction (RERI = -0.26, 95% CI = -0.91; 0.40). When dichotomizing subscales at the median, differential effects of subscales were not found. When dividing subscales into categories based on value ranges, differential effects for job control subscales (namely, decision authority and skill discretion) were found (p = 0.04). This study does not support all assumptions of the DC model: (1) it corroborates previous studies not finding an interaction of psychological demands and job control; and (2) signs of differential subscale effects were found regarding job control. Too few prospective studies have been carried out regarding differential subscale effects.

[Psychosocial stress at work and disease risks : Scientific evidence and implications for practice]. / Psychosoziale Arbeitsbelastungen und Erkrankungsrisiken : Wissenschaftliche Evidenz und praktische Konsequenzen.

The modern working world makes a significant contribution to the development of diseases, which goes far beyond the field of traditional occupational diseases. Despite technological progress and successful medical healthcare, distinct widely disseminated psychosocial working conditions contribute to a remarkable burden of work-related diseases. By inducing chronic activation of psychobiological stress reactions, they promote the development of various physical and mental disorders. To identify "toxic" constellations within the complexity and variability of modern work environments, a theoretical model is required. It aims at delineating core critical elements at a level of generalization that enables their identification in a wide range of occupations. This article describes the leading theoretical work stress models in the international research and it demonstrates their contribution towards explaining elevated disease risks among employees. Research based on prospective epidemiologic cohort studies focused specifically on depressive disorders and coronary heart diseases. Two theoretical concepts received particular attention, the demand-control and the effort-reward imbalance models. Results derived from meta-analyses indicate increased relative risks of these disorders in the range of 35-80% among those exposed to these stressors compared to nonexposed groups. Finally, practical implications of this scientific evidence for worksite screening and health promoting activities are discussed.

The impact of social comparisons of job demands and job control on well-being.

We extended the job demand-control model by including a social comparison perspective and hypothesised that an employee's work-related well-being is to some degree relative to the perceived work environment of coworkers rather than absolute (in terms of isolated effects of individual work characteristics). Hence, we account for the social context when examining the effects of individual job characteristics. Using a lagged study design with two measurement times eight weeks apart, we examined the effects of the (in)congruence between one´s own job demands and job control with the perceived job demands and job control of coworkers on job satisfaction, emotional exhaustion, cynicism, and professional efficiency. Findings from polynomial regression analyses and response surface methodology revealed that perceiving coworkers as having either higher or lower demands than oneself is associated with lower job satisfaction and higher levels of emotional exhaustion. This provides partial support for our hypotheses. We found first-time evidence that social comparison processes regarding job demands can influence employees´ well-being.

Time is on My Side-or Is It? Assessing How Perceived Control of Time and Procrastination Influence Emotional Exhaustion on the Job.

The job demands-control model (JDC) postulates that an increased control over work resources mitigates or "buffers" the positive association between job stressors and strainers. However, the inconclusive validation of the buffering hypothesis across multiple studies suggests the need for fresh approaches, both conceptual and methodological. We integrated aspects of the JDC framework and time management process models to construct a model that tested both the direct and indirect effects of the perceived control of time (PCT) on emotional exhaustion arising from workload demands. Furthermore, we tested whether procrastination tendencies moderated the benefits of PCT on work stressors and strains. Data were collected in an Internet survey with 356 US adult office workers obtained from Prolific. The results supported the buffering effect of PCT on emotional exhaustion. PCT both mediated and exerted direct effects on the relationship between workload and emotional exhaustion. Procrastination tendencies moderated PCT and, in turn, undermined high PCT ability to reduce emotional exhaustion. Overall, the findings suggested that giving workers more control over their time may reduce stress associated with demanding workloads. However, chronic procrastinators may benefit less from having more control over time resources if they are not provided with tools to help them self-regulate more effectively.

Demands, Control, Goal-related Feedback, and Case Managers' Affective Well-being: A Two-sample Mediation Study.

Purpose: An understudied, but important, topic within the social work literature is the affective well-being of human service case managers. The groundbreaking demand-control (DC) model predicts additive effects for job demands and job control on job-related affective well-being. Meta-analytic data and comprehensive literature reviews report inconclusive findings for this classic additive model.Method: This two-sample cross-sectional field survey study sought to address both issues by testing a recently introduced modified additive model using 810 human service case managers from the state of New York.Results: Mediational analyzes (i.e., structural equation modelling and bootstrapping) confirmed goal-related feedback's intervening role on the job control-wellbeing relationship for each sample.Discussion: Results not only contribute uniquely to the evidence-based social work literature, but also help clarify forty years of inconsistent classic additive model findings.

Is physical and psychological work stress associated with fatigue in Danish ferry ship employees?

BACKGROUND: Fatigue is a recognised risk factor for safety in seafaring. While always dangerous, fatigue in ferry shipping is especially hazardous as it may jeopardise passengers' safety. To counteract fatigue, knowledge on its determinants is important. Little, however, is known on the influence from physical and psychosocial work environment factors within ferry shipping. The aim of the study was to investigate the association between work stress in terms of physical stressors, perceived job demands and job control and different dimensions of fatigue among ferry ship employees and to test whether a potential effect of work stress was mediated by sleep satisfaction. MATERIALS AND METHODS: The design was cross-sectional. 193 respondents answered to a self-administered questionnaire including standardised scales, i.e. the Swedish Occupational Fatigue Inventory and the Copenhagen Psychosocial Questionnaire for job demands and control. The association of risk factors with fatigue was determined using hierarchical multiple linear regression analyses. RESULTS: Physical work stressors were positively associated with only one of five fatigue subscales: lack of energy. Higher levels of demands were related to more lack of energy, lack of motivation, physical exertion and sleepiness, while more control was related to lesser lack of energy, lack of motivation and sleepiness. No demand-control interaction was found. Effects of demand and control were partly mediated by sleep satisfaction. CONCLUSIONS: Although limited by its cross-sectional design this study provides support for the independent relevance of demands and control for employee fatigue in ferry shipping and for a mediating role of sleep satisfaction.

Combined Use of Job Stress Models and the Incidence of Glycemic Alterations (Prediabetes and Diabetes): Results from ELSA-Brasil Study.

Evidence of psychosocial stress at work as a risk factor for diabetes and prediabetes is restricted. OBJECTIVES: Analyze the independent and combined association of the models, demand-control and social support (DC-SS) and the effort-reward imbalance and overcommitment (ERI-OC), and the incidence of glycemic alterations (prediabetes and diabetes). METHODS: A prospective study was carried out with data from 7503 active workers from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) study in the period 2008-2014. Work stress was measured by two stress models. Glycemic levels were evaluated by glycated hemoglobin (HbA1c) in two moments and classified in four groups: normal, maintenance of prediabetes, incident prediabetes, and incident diabetes. Multinomial logistic regression was analyzed with 5% significance levels stratified by sex, and multiplicative interactions were investigated. RESULTS: Work stress and glycemic alterations were more frequent in women. Psychosocial stress at work was shown to be associated to the risk of prediabetes and diabetes only among women. For women, the combination of models enlarged the magnitude of the association: prediabetes (DC-ERI = OR 1.51, 95% CI 1.15-1.99) and diabetes (DC-ERI = OR 2.10, 95% CI 1.20-3.65). Highly-educated women exposed to ERI-OC were four times more likely to have diabetes. CONCLUSION: Both models may contribute to explaining the psychosocial stress load according to each pattern of glycemic alteration among women.

Effects of two occupational stress models on depressive symptom of employees in a mould-producing enterprise / 中国职业医学

OBJECTIVE: To explore the influencing factors of depressive symptom of employees in a mould-producing enterprises using two occupational stress models. METHODS: A total of 457 employees in a mould-producing enterprise were selected as study subjects using cluster sampling method. The Center for Epidemiological Study-Depression Scale, the Chinese version of Job Demand Content Questionnaire and the Effort-Reward Imbalance Questionnaire were used to investigate the level of depressive symptom and occupational stress by the job demand control(JDC) model and effort reward imbalance(ERI) model. RESULTS: Among the 457 employees, the median score of depressive symptom was 11.00, the detection rate of depressive symptom in the subjects was 23.4%(107/457). The incidence of occupational stress by the JDC and ERI models was 78.3%(358/457) and 62.6%(286/457), respectively. The rate of depressive symptom was statistically higher in the high occupational stress group than that of the low occupational stress group by the ERI model(26.6% vs 18.1%, P<0.05). The multivariate logistic regression analysis showed that both marital status and monthly income were influencing factors of depressive symptom by the JDC model(P<0.05). The marital status, monthly income and occupational stress were influencing factors of depressive symptom by the ERI model(P<0.05). The risk of depressive symptom was statistically higher in the high occupational stress group than that of the low occupational stress group(P<0.05). CONCLUSION: Employees in mould-producing enterprise have some depressive symptom. The marital status, monthly income and occupational stress by the ERI model are the main influencing factors of depressive symptom.

Effort-Reward Imbalance and Job Strain: A Composite Indicator Approach.

The Job Demand-Control-Support (JDC-S) and Effort-Reward Imbalance (ERI) models dominate psychosocial work environment research and practice, with their independent and collective contributions to employee health having been extensively demonstrated. Psychosocial risk assessment in the humanitarian aid sector is in its infancy, and there is a need to identify appropriate psychosocial work environment models to inform approaches to assessment. The aim of this study is to examine the efficacy of these models separately and in combination to identify psychological distress in humanitarian aid workers. Cross-sectional survey data were obtained from 283 humanitarian aid workers. Logistic regression analyses investigated the separate and combined ability of the models to identify psychological distress. More than half of the participant sample reported psychological distress, and one third reported high ERI and high job strain. When tested separately, each model was associated with a significantly elevated likelihood of psychological distress. When tested in combination, the two models offered a superior estimation of the likelihood of psychological distress than achieved by one model in isolation. Psychosocial risk assessment in the humanitarian aid sector encompassing the characteristics of both these leading psychosocial work environment models captures the breadth of relevant generic psychosocial work characteristics. These initial findings require corroboration through longitudinal research involving sector-representative samples.
