The Association of Occupational Stress and Depressive Symptoms among Employed Persons with Benign Breast Disease: The Mediating Role of Psychological Capital

The Relationship Between Work-Related Stress and Depression: A Scoping Review

Objectives

Work-related stress is highly prevalent. Recent systematic reviews concluded on a significant association between common work-related stress measures and depression. Our scoping review aims to explore whether work-related psychosocial stress is generally associated with depression or depressiveness, the extent and methodology of the primary research undertaken on this topic and to elucidate inconsistencies or gaps in knowledge.

Methods

We searched for literature in Pubmed, PsycInfo and Web of Science including full reports in seven languages published between 1999 and 2022 and applied the PRISMA statement for scoping reviews criteria.

Results

Of 463 primarily identified articles, 125 were retained after abstract and full-text screening. The majority report significant associations between work-related stress and depression. Cross-sectional studies are most prevalent. Sufficient evidence exists only for job strain and effort-reward imbalance. Most studies are from Asia, North America and Europe. The health sector is the most studied. Several research gaps such as the lack of interventional studies were identified.

Conclusion

The consistency of most studies on the significant association between work-related stress and depression is remarkable. More studies are needed to improve evidence and to close research gaps.

Association between breast nodules, anxiety, depression and metabolic risk factors in a Chinese cohort

Background

The relationship between anxiety, depression, and metabolic parameters and the incidence of breast nodules is unclear. This study aims to investigate the association between female breast nodules and anxiety, depression and metabolic factors.

Methods

This cross-sectional study recruited 857 individuals with biological indicators and breast ultrasound data from the Daping hospital from April 2021 to February 2022. Serum samples were used to measure fasting blood glucose, uric acid, triglycerides, total cholesterol, urea nitrogen, alanine transaminase, aspartate transaminase, albumin, high-density lipoprotein, low-density lipoprotein. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess the level of anxiety and depression.

Result

The positive rate of breast nodules in women aged 40 to 49 years old was significantly higher than that of other age women. The proportion of participants aged 40-49 years old in the group with breast nodules was significantly higher than that in the group without breast nodules (34.6% vs. 16.9%, p<0.001). Breast nodules in postmenopausal women were significantly lower than those in premenopausal women (26.4% vs. 73.6%, p = 0.026). The SAS scores of women with breast nodules were higher than those of the no-nodules group (40.99 ± 8.45 vs. 38.94 ± 6.89, p<0.001), same as the SDS scores (41.97 ± 10.33 vs. 38.91 ± 7.60, p < 0.001). The number of women suffering from anxiety in the group of breast nodules was significantly higher than that in control (13.8% vs. 4.5%, p < 0.001), and the number of depression in the group of breast nodules was also significantly higher than that of in control (14.4% vs. 4.5%, p < 0.001). Women with breast nodules showed a slightly lower uric acid level than those without breast nodules (290.11 ± 65.32 vs. 301.43 ± 65.93 umol/L, p = 0.016). Multivariable logistic regression analysis showed that age, menopausal status, anxiety and depression status were significantly associated with the presence of breast nodules, but there was no significant difference in uric acid.

Conclusion

Our findings offer insight into the occurrence of depression and anxiety in the breast nodules of Chinese women. Anxiety and depression status, age and menopausal status may be the independent risk factors for the occurrence of breast nodules.

Relationships between depression, self-efficacy, and professional values among Chinese oncology nurses: a multicenter cross-sectional study

OBJECTIVES

Many factors are related to oncology nurses' professional values. However, the evidence on the relevance of professional values among oncology nurses in China remains sparse. This study aims to investigate the relationship between depression, self-efficacy, and professional values among Chinese oncology nurses and analyze the mediating effect of self-efficacy on this association.

METHODS

It was a multicenter cross-sectional study designed with the STROBE guidelines. An anonymous online questionnaire recruited 2530 oncology nurses from 55 hospitals in six provinces of China between March and June 2021. Measures included self-designed sociodemographic and fully validated instruments. Pearson correlation analysis was employed to explore the associations between depression, self-efficacy, and professional values. Bootstrapping analysis by the PROCESS macro was used to examine the mediating effect of self-efficacy.

RESULTS

The total scores of depression, self-efficacy, and professional values of Chinese oncology nurses were 52.75 ± 12.62, 28.39 ± 6.33, and 101.55 ± 20.43, respectively. About 55.2% of Chinese oncology nurses were depressed. Chinese oncology nurses' professional values were generally intermediate. Their professional values were negatively related to depression and positively correlated with self-efficacy, while depression was negatively related to self-efficacy. Moreover, self-efficacy partially mediated the relationship between depression and professional values, accounting for 24.8% of the total effect.

CONCLUSIONS

Depression negatively predicts self-efficacy and professional values, and self-efficacy positively predicts professional values. Meanwhile, depression in Chinese oncology nurses has an indirect effect on their professional values through self-efficacy. Nursing managers and oncology nurses themselves should develop strategies aimed at relieving depression and improving self-efficacy to strengthen their positive professional values.

Decorin inhibits the formation of hard nodules after microwave ablation by inhibiting the TGF-β1/SMAD and MAPK signaling pathways: in a Bama miniature pig model of mammary gland hyperplasia

BACKGROUND

Benign breast lesions are often associated with hard nodule formation after microwave ablation (MWA), which persists for a long time and causes problems in patients. The aim of this study was to evaluate the efficacy of decorin in the treatment of hard nodule formation and its potential mechanism of action.

METHODS

Using a Bama miniature pig model of mammary gland hyperplasia, immunohistochemistry, Masson's trichrome and western blotting were firstly applied to compare the extent of fibrosis and activation of key members of the TGF-β1/SMAD and MAPK signaling pathways of hard nodule in the control and MWA groups, and then the extent of fibrosis and expression of signaling pathways in hard nodule were examined after application of decorin.

RESULTS

The results showed that the MWA group had increased levels of TGF-β1, p-SMAD2/3, p-ERK1/2, and collagen I proteins and increased fibrosis at 2 weeks, 4 weeks, and 3 months after MWA. After decorin treatment, the expression levels of each protein were significantly downregulated, and the degree of fibrosis was reduced at 2 weeks, 4 weeks, and 3 months after MWA compared with the MWA group.

CONCLUSION

In conclusion, these results suggest that activation of TGF-β1 may play an important role in hard nodule formation and that decorin may reduce hard nodule formation after MWA in a model of mammary gland hyperplasia by inhibiting the TGF-β1/SMAD and MAPK signaling pathways.

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.

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

Background

Nurses are in high-pressure, high-load, and high-risk environment for a long time, and their insomnia cannot be ignored. Insomnia not only has a negative impact on the physical and mental health of nurses, but also on the efficiency and quality of nursing work.

Objective

The purpose of this study was to investigate the multiple mediating effect of psychological capital, effort-reward ratio, and overcommitment in the relationship between perceived organizational support and insomnia among Chinese nurses.

Methods

A cross-sectional study has been carried out in a tertiary grade A hospital in Shandong Province, China from March 2021 to May 2021. The demographic questionnaire, Perceived Organization Support Questionnaire, Psychological Capital Questionnaire, Chinese version Effort-Reward Imbalance, Questionnaire and Athens Insomnia Scale were used for data collection. SPSS PROCESS 3.4 macro program developed by Hayes was used to test the serial multiple mediation. Descriptive analysis, independent-samples t-test, one-way analysis of variance, Pearson's correlation analyses, ordinary least-squares regression, and the bootstrap method were used for data analysis.

Results

658 valid questionnaires were collected (81.2%). Nurses' perceived organizational support was positively correlated with psychological capital (r = 0.455, p < 0.001), and was significantly negatively correlated with effort-reward ratio (r = -0.318, p < 0.001), overcommitment (r = -0.328, p < 0.001), and insomnia (r = -0.358, p < 0.001); Psychological capital was negatively correlated with effort-reward ratio (r = -0.275, p < 0.001), overcommitment (r = -0.339, p < 0.001), and insomnia (r = -0.402, p < 0.001), respectively; effort-reward ratio and overcommitment were significantly positively correlated with insomnia (r = 0.379, p < 0.001; r = 0.466, p < 0.001), respectively. In the model of perceived organizational support-psychological capital-effort-reward ratio-insomnia, the overall mediating effect was -0.080 (95%CI: -0.109 ~ -0.058), and the mediating effect of psychological capital was -0.050, accounting for 34.30% of the total effect; the mediating effect of effort-reward ratio was -0.024, accounting for 16.49% of the total effect; the chain mediating effect of psychological capital and effort-reward ratio was -0.007, accounting for 4.49% of the total effect. In the model of perceived organizational support-psychological capital-overcommitment-insomnia, the overall mediating effect was -0.085 (95%CI: -0.109 ~ -0.064), and the mediating effect of psychological capital was -0.042, accounting for 28.64% of the total effect; the mediating effect of overcommitment was -0.029, accounting for 19.81% of the total effect; the chain mediating effect of psychological capital and overcommitment was -0.015, accounting for 10.14% of the total effect.

Conclusion

Perceived organizational support had direct negative influence on insomnia. Psychological capital and effort-reward ratio/overcommitment acted as chained mediating factor could partially relieve insomnia symptoms related to perceived organizational support. It is suggested to improve the level of organizational support and psychological capital of nurses, and reduce the effort-reward imbalance and overcommitment of nurses, so as to effectively decline and deal with nurses' insomnia.

The Effect of Psychological Capital and Role Conflict on the Academic Entrepreneurial Intents of Chinese Teachers in Higher Education: A Study Based on the Theory of Planned Behavior

Because academic entrepreneurship is an innovation driving force in China's economy, teachers are key knowledge creators in the process of entrepreneurship. Therefore, it is particularly important to give attention to the individual psychological mechanism factors at play in the process of teachers in higher education academic entrepreneurship. The purpose of this study is to identify individual psychological capital and role conflict issues among university teachers in China. To accomplish this aim, we investigated the emergence of positive academic entrepreneurial intents, continued through the process of academic entrepreneurship, and clarified the impact of psychological capital and role conflict on entrepreneurial intent. Based on the theory of planned behavior, we constructed a research model from the perspective of entrepreneurial intent prior to entrepreneurial action. We established a cohort of teachers in 17 higher education institutions (N = 525) in southern China, with psychological capital and role conflict as the prior independent variables and the teachers' academic entrepreneurial intent as the dependent variable. Using quantitative analysis, SPSS 22.0, and AMOS 23.0, we conducted reliability and validity tests, correlation analysis, and structural equation models on the collected data. We reached the following conclusions: (1) psychological capital has a positive effect on attitudes toward academic entrepreneurship; (2) psychological capital has a positive effect on perceived behavioral control; (3) role conflict has a negative effect on perceived behavioral control; (4) academic entrepreneurial attitudes have a positive effect on academic entrepreneurial intent; (5) perceived behavioral control has a positive effect on academic entrepreneurial intent; (6) subjective norms have a positive effect on academic entrepreneurial intent. We also provide some suggestions about academic entrepreneurship for university administrators.

Believe-in counterfactual thinking and psychological capital

Counterfactual thinking puts a negative reality and better or worse alternative outcomes in the mind simultaneously. The implicit theory of intelligence considers whether individuals believe that intelligence can be promoted by effort or not. Previous studies suggest that counterfactual thinking interacting with the implicit theory of intelligence would evoke a belief in an attainable future or a belief that a certain future could one day be reality, thereby producing positive effects. Three studies examined the hypothesis that belief in an attainable future through counterfactual thinking would predict psychological capital, which is a positive developmental state of individuals. In Study 1 ( N = 62), belief in an attainable future was operationalized by introducing the implicit theory of intelligence and counterfactual thinking. Incremental theorists had higher psychological capital when engaged in counterfactual thinking than controls. In Study 2 ( N = 71), belief in an attainable future was operationalized by introducing the likelihood of the antecedents and of the outcomes, which were conceptualized as how people believe in their counterfactual thinking. Belief in an attainable future predicted psychological capital even after controlling for the influence of future time perspective and present-fatalistic time perspective, two concepts that depict how individuals process time-related information. In Study 3 ( N = 76), we conducted an intervention study. Participants in the experimental group were directed to construct attainable counterfactual thinking for one week. The experimental group had higher psychological capital than the control group. Across three studies, the findings consistently provided primary support for the hypothesis that belief in an attainable future would predict psychological capital.

Efficacy of Entrepreneurs' Psychological Capital on the Performance of New Ventures in the Development of Regional Economy in the Greater Bay Area

The study aims to analyze the relationship between the psychological capital and enterprise performance of the entrepreneurs and provide direction for the optimization of regional economic development and talent introduction mechanism. First, the theoretical basis is established from regional economic development, innovative talent introduction, and individual psychological capital theory, according to which the questionnaire survey is designed, and four dimensions of self-efficacy (C), wish (W), toughness (T), and optimism (O) are selected to set the questions on psychological capital and innovation performance. Then, following statistical analysis, the characteristics of the new ventures are revealed. Finally, based on the empirical research model, the hypotheses are put forward based on psychological capital and its four subdimensions, and the relationship between the efficacy of the psychological capital and the performance of new ventures of the entrepreneurs is revealed through regression analysis. The results show that the proportion of the computer and education industry in the new ventures reaches 67.7%, and the proportion of enterprises with 1–5 entrepreneurial years reaches 78%. Meanwhile, the proportion of first-time entrepreneurship is 60.5%, and the proportion of entrepreneurs motivated by their ideal reaches 35.8%. The new entrepreneurs have a good grasp of the market situation, and the overall operation condition is stable. Most of them originate from micro and small enterprises (MSE). Psychological capital has a great influence on individual entrepreneurship. The empirical results show that the psychological capital of entrepreneurs has a positive effect on the performance of new ventures. Except for the subdimension of O, the other three subdimensions (C, T, and W) of psychological capital have a positive effect on the performance of new ventures, and psychological capital as a whole has the greatest impact. The results provide a reference for the relationship between the performance improvement of new ventures and regional economic development.

Identifying the risk features for occupational stress in medical workers: a cross-sectional study

Objective

Occupational stress is considered a worldwide epidemic experienced by a large proportion of the working population. The identification of characteristics that place people at high risk for occupational stress is the basis of managing and intervening in this condition. In this study, we aimed to identify and validate the risk features for occupational stress among medical workers using a risk model and nomogram.

Methods

This cross-sectional study included 1988 eligible participants from Henan Province in China. Occupational stress and worker-occupation fit were measured with the Depression, Anxiety and Stress Scales (DASS-21) and Worker-Occupation Fit Inventory (WOFI). The identification of risk features was achieved through constructing multiple logistic regression model, and the risk features were used to develop the risk model and nomogram. Receiver operating characteristic (ROC) curves and calibration plots were generated to assess the effectiveness and calibration of the risk model.

Results

Among 1988 participants in our study, there were 42.5% (845/1988) medical workers experienced occupational stress. The risk features for occupational stress included poor work-occupation fit (WOF score < 25, expected risk: 77.3%), nurse population (expected risk: 63.1%), male sex (expected risk: 67.2%), work experience duration of 11–19 years (expected risk: 54.5%), experience of a traumatic event (expected risk: 65.3%) and the lack of a regular exercise habit (expected risk: 60.2%). For medical workers who have these risk features, the expected risk probability of occupational stress would be 90.2%.

Conclusion

The current data can be used to identify medical workers at risk of developing occupational stress. Identifying risk features for occupational stress and the work-occupation fit can support hierarchical stress management in hospitals.

Mediating role of psychological capital in the relationship between social support and treatment burden among older patients with chronic obstructive pulmonary disease

This study was conducted to investigate the connection between social support and the treatment burden among older patients with chronic obstructive pulmonary disease (COPD), and to examine the mediating role of psychological capital within that connection. Although treatment burden is common, the current data on social support associated with it is limited, and the theoretical mechanisms underlying the relationship between the two variables have not yet been clarified. A total of 245 older outpatients with COPD were recruited. Descriptive and Structural Equation Modelling was employed to test the hypothesised model using SPSS 26 and IBM SPSS AMOS 26. The modified model yielded an adequate fit to the data. The variation in the treatment burden explained by the hypothetical model was 57.2%. The study provides a new perspective for medical professionals to manage the treatment burden by developing efficient social support and psychological capital measures.

Anxiety and Depression in Women Newly Diagnosed with Breast Cancer and Waiting for Surgery: Prevalence and Associations with Socio-Demographic Variables

Background and Objectives: Cancer is a threatening-life disease with a significant psychological burden. The psychological morbidity varies according to the phases of the illness and is influenced by multiple socio-demographic factors, that are useful to consider in order to identify the categories of patients most at risk of developing psychiatric disorders. The present study analyzes, in a sample of women newly diagnosed with breast cancer, the relationships between their levels of anxiety and depression and several socio-demographic characteristics. The study was cross-sectional. Materials and Methods: Four hundred and seventy eight women newly diagnosed with breast cancer completed the Hospital Anxiety and Depression Scale during the pre-surgical phase. Results: Findings show that almost 40% of the sample had clinically relevant anxious symptoms and about a quarter of the sample had significant depressive symptoms. Their prevalence was higher in widows. Moreover, depressive symptoms were higher in older women and anxious symptoms were higher in patients with a lower educational level. In the pre-surgical phase, women can suffer from clinically relevant anxiety and depression, especially the widows, older women, and women with a lower educational level. Conclusions: Identifying the most psychologically vulnerable patients, due to specific socio-demographic characteristics, is essential in order to provide adequate psycho-oncological treatments to the categories of patients, who are most at risk of developing psychopathological concerns.

The relationship between psychological capital and mental health during the Covid-19 pandemic: A longitudinal mediation model

The new Coronavirus has impacted people's lifestyles, stress, and well-being. Thus, they need personal positive resources to help them during challenging circumstances. With this longitudinal study on 290 participants, we analyzed the relationship between psychological capital (PsyCap), measured at the beginning of the lockdown period and some indicators of mental health (depression, anxiety, satisfaction with life) measured after 2 months. Moreover, we examined whether stress (at Time 2) mediates the relationships. Following structural equation modeling (SEM) analyses, the results show that PsyCap has a significant positive effect on satisfaction with life and significant negative effects on depression and anxiety. Stress mediated all the relationships.

Hereditary and breastfeeding factors are positively associated with the aetiology of mammary gland hyperplasia: a case-control study

BACKGROUND

Hyperplasia of mammary gland (HMG) has become a common disorder in women. A family history of breast cancer and female reproductive factors may work together to increase the risk of HMG. However, this specific relationship has not been fully characterized.

METHODS

A total of 1881 newly diagnosed HMG cases and 1900 controls were recruited from 2012 to 2017. Demographic characteristics including female reproductive factors and a family history of breast cancer were collected. A multi-analytic strategy combining unconditional logistic regression, multifactor dimensionality reduction (MDR) and crossover approaches were applied to systematically identify the interaction effect of family history of breast cancer and reproductive factors on HMG susceptibility.

RESULTS

In MDR analysis, high-order interactions among higher-level education, shorter breastfeeding duration and family history of breast cancer were identified (odds ratio [OR] 7.07 [95% confidence interval {CI} 6.08 to 8.22]). Similarly, in crossover analysis, HMG risk increased significantly for those with higher-level education (OR 36.39 [95% CI 11.47 to 115.45]), shorter duration of breastfeeding (OR 27.70 [95% CI 3.73 to 205.70]) and a family history of breast cancer.

CONCLUSION

Higher-level education, shorter breastfeeding duration and a family history of breast cancer may synergistically increase the risk of HMG.

Assessment of psychological capital at work by physiotherapists

OBJECTIVE

Describe how psychological capital in the workplace impacts job satisfaction and quality life among Brazilian physiotherapists.

METHODS

Questionnaires were distributed to physiotherapists of the Brazilian Physical Therapists Association working in clinical or managerial positions in the public or private sector. The response rate was 12%, with 389 participants.

RESULTS

Job satisfaction was associated with self-efficacy, hope, optimism, and resilience, showing a direct relationship between satisfaction and psychological capital in the workplace. The self-employed physiotherapists were more satisfied and had higher psychological capital in the workplace than the physical therapists employed by a company.

CONCLUSION

It is relevant that managers in the physiotherapy field recognize the relevance of psychological capital in the workplace and use it in their management practices. Understanding the individual characteristics of each employee is essential in promoting the personal development of physical therapists. This finding contributes to a healthier and more challenging work environment for physiotherapists in addition to developing their careers in physical therapy units.
