The relationship between big data capability, supply chain collaborative innovation and operational performance in Chinese manufacturing sector

Big data has now become a hot topic and focus of common concern in academia and practitioners. Data collection, storage, analysis, and processing require enterprises to improve their big data capability (BDC), which are increasingly valued by companies to create greater value. Supply chain collaborative innovation (SCCI) can enable companies to improve products and services. Many scholars have realized the positive effect of BDC on the improvement of enterprise performance, however, most of the extant literature focuses on direct effects of BDC on enterprise performance, and there is a lack of analysis of its impact transmission process. From the perspective of SCCI, and based on the theory of resource-based view (RBV) and theory of dual innovation (DI), this research analyzes the intermediary effect of SCCI as a complementary asset between BDC and enterprise operational performance (EOP), and reveals that BDC affect EOP by way of impact transmission mechanism. All the relationships between the three constructs (BDC, SCCI and EOP) are investigated by the empirical study. Subject to systematical review of existing literature from both China and overseas countries, and based on the theory of RBV, this paper categorizes BDC into three sub-capabilities: big data resource integration (BDRI), big data in-depth analysis (BDIDA) and big data application (BDA);based on the theory of dual innovation, SCCI is divided into two variables: breakthrough innovation (BI) and gradual innovation (GI). A theoretical framework is then developed and three research hypotheses are proposed accordingly: H1. Big data capabilities have a positive effect on supply chain collaborative innovation;H2. Supply chain collaborative innovation has a positive effect on enterprise operational performance;H3. Supply chain collaborative innovation plays a mediating role in the relationship between big data capabilities and enterprise operational performance. Empirical research methods using a large-scale questionnaire collection and analysis of primary data are employed to test whether the research hypothesis are accepted or rejected, and conclusions are drawn subsequently. The research employs questionnaire survey to collect data from Chinese manufacturers in the automotive and electronics sectors as these two sectors are ideal to investigate the impact transmission mechanism between big data capability and enterprise operational performance, as they have relatively good understanding and high level of informatization with good BDC. Sample enterprises are located in both coastal provinces and inland areas. The questionnaire was designed subject to both intensive and extensive literature review. The data collection started in early May 2020 and ended in November 2020. Due to Covid-19, most of the questionnaires were collected by emails or Questionnaire Star. A total of 330 responses were received and 15 responses were discarded due to data missing or reliability judgement, leaving 315 valid responses for further data analysis. Exploratory factor analysis was performed employing SPSS 25. 0. The KMO and Bartlett sphere test results were good, then the principal component analysis was used to extract the factors whose characteristic roots were greater than 1. The results showed that all the items of BDC were aggregated into 3 factors, and the cumulative variance explanation rate reached 76. 548%;all the items in SCCI were aggregated into 2 factors, and the cumulative variance explanation rate reached 83. 757 %;all items of the EOP were aggregated into one factor, and the variance explanation rate was 77. 530%, which is consistent with the dimensions of the scale designed in this study, indicating that the quality of the questionnaire data was good. This was followed by reliability test and validity test and all the test results were satisfying. Structural equation modelling (SEM) was used for the data analysis employing Amos 24. The test results show: χ2 / df =1. 823<3, RMSEA =0. 062<0. 08, CFI = 0. 953>0. 9, NFI = 0. 903>0. 9, TLI = 0. 947>0. 9. All ndicators are within the acceptable range, indicating that the model fits well with the sample data. The results of path analysis show that BDRI has a significant impact on both BI and GI;the BDIDA does not reach the significance level for the path of BI and GI;the BDA has a positive effect on BI and GI respectively;the BI and GI have a positive effect on EOP respectively. Following this, the mediating role of SCCI was tested by Bootstrap. The test results show that BI does not play a mediating role between BDC and EOP;however, GI does play a mediating role between BDC and EOP. The conclusions are drawn as follows by the empirical study. Firstly, BDC can positively promote SCCI;Secondly, SCCI can positively affect EOP;Thirdly, SCCI plays a mediating role between BDC and EOP. Theoretically, this research reveals that intermediary effect of SCCI as a complementary asset between BDC and EOP, which enriches literature by adding mechanism of other influencing factors on the path of BDC positively affecting EOP. Practically, this study has clarified a specific transmission path for BDC to improve EOP, i. e., enterprises should vigorously cultivate big data to improve their EOP, meanwhile focus more on the intermediary effect of SCCI © 2023, Journal of Industrial Engineering and Engineering Management.All Rights Reserved.

Analysis of the Impact of Industrial Structure Upgrading and Energy Structure Optimization on Carbon Emission Reduction

In China, there has been a significant increase in carbon emissions in the new era. Therefore, evaluating the influence of industrial structure upgrades and energy structure optimization on reducing carbon emissions is the objective of this research. Based on the provincial panel data of 30 provinces and cities across China from 1997 to 2019, this paper builds up a fixed-effect panel quantile STIRPAT model to investigate the differences in the impact of industrial structure on carbon emission intensity at different quantile levels from the provincial perspective, and as a way of causality test, the mediation effect model is adopted to empirically test the transmission path of "industrial structure upgrading-energy structure optimization-carbon emission reduction". The research results show that: (1) Both industrial structure upgrades and energy structure optimization have significant inhibitory effects on carbon emissions, and there are regional heterogeneities. (2) The upgrading of industrial structure has a significant positive effect on optimizing energy structure. (3) The upgrading of industrial structure can not only directly restrain carbon emissions but also indirectly have a significant inhibitory effect on carbon emissions by promoting the optimization of energy structure. Based on the above conclusions, corresponding policy recommendations are proposed to provide suggestions for China to achieve the goal of carbon neutrality.

China-Europe freight transportation under the first wave of COVID-19 pandemic and government restriction measures

International freight transportation experienced significant disruptions during the COVID-19 pandemic. The impact of the pandemic and related government restriction measures on international freight transportation is worth analysing for the development of transportation policies and practices in the post-pandemic period, but has received limited attention. To fill the gap, this study applies structural equation models to analyze the impact of the COVID-19 pandemic on the international transportation market and the relationships among the pandemic, government restriction measures, and international transportation market. The impact is also differentiated for different modes of transportation. Results confirm that both demand and supply of interna-tional transportation services have been negatively affected by the first wave of the pandemic, with sea trans-portation being more affected by the reduction of demand and air transportation more by the supply volatility. The government restriction measures are found to play a mediation role, in the way that the impact of the pandemic on the supply of transportation service is suppressed through the government restriction measures. Our findings provide important guidance for transportation industry players and governments in their decision-making process facing with global market shocks such as a pandemic.

A study on the influence of community spiritual comfort service on the mental health of older people.

Background: China is experiencing rapid population aging, with the proportion of older adult people aged 60 and above reaching 19. 8% of the total population in 2022. With the growth of age, the physical function of older adults declines and their mental health is getting worse, with the increasing trend of empty nesting and childlessness, older adults lack information and social interaction with others and fall into social isolation, loneliness and some mental health problems, the proportion of older adults with mental health problems gradually rises and the mortality rate increases incrementally, requiring effective ways to intervene in the mental health of older adults and promote healthy aging. Aim of the study: The present study investigated the influence of spiritual comfort older adult services on the mental health of 12,624 older adults aged 60 years or older in 23 provinces in China from 2017 to 2018, with the aim of providing a case for the development of more targeted mental health strategies for older people. Methods: Using the data from the 2018 CLHLS Survey, the influencing factors of the mental health of older people were analyzed using chi-square test and the logit regression model. The mechanism of the health care facilities and the spiritual comfort services on mental health was analyzed using the chain mediation effect. Results: The spiritual comfort services decreased the risk of negative emotion and mental health of older adults, with female (OR = 1.168), rural residents (OR = 1.385), no drinking (OR = 1.255), not exercising (OR = 1.543), not having pension insurance (OR = 1.233), and low annual household income (OR = 1.416) being the characteristics as risk factors. The mediating effect results showed that the health care facilities had a partial mediating effect between the spiritual comfort services and the mental health status of older people, and the mediating effect accounted for 40.16% of the total effect. Conclusions: The use of spiritual comfort services can effectively reduce and alleviate the adverse mental health symptoms of older people, promote guidance and health education for healthy older people and chronically ill patients, and improve the good health perception of older people in order to improve their quality of life and mental health status.

Moral injury and suicidal ideation among health professionals: The role of mental health.

BACKGROUND: The prolonged COVID-19 pandemic has burdened health professionals mentally and physically. This study aims to explore the relationship between moral injury (MI) and suicidal ideation (SI), and the role of mental health conditions in this relationship. METHODS: Three-wave repeated online cross-sectional study with a total of 10,388 health professionals were conducted in different stages (2020-2022) of the COVID-19 pandemic in mainland China. Participants completed the Chinese version of the Moral Injury Symptoms Scale-Health Professional, Post-Traumatic Stress Disorder (PTSD) Checklist for DSM-5 coupled with a blanket of scales. RESULTS: The prevalence of SI and MI among health professionals was 9.8 % and 40.2 %, respectively. The prevalence risk of SI was lower in wave 2 (OR = 0.64, 95 % CI: 0.54-0.77) and wave 3 (OR = 0.71, 95 % CI: 0.60-0.84) when compared with wave 1. MI (OR = 4.66, 95 % CI: 3.99-5.43), medical error (OR = 1.15, 95 % CI: 1.00-1.32), workplace violence (OR = 1.13, 95 % CI: 0.97-1.32), depression (OR = 94.08, 95 % CI: 63.37-139.69), anxiety (OR = 25.54, 95 % CI: 21.22-30.74), PTSD (OR = 24.51, 95 % CI: 19.01-31.60) were associated with a higher risk of SI. The mediation model revealed that depressive, anxiety, and PTSD symptoms explained 90.6 % of the total variance in the relationship between MI and SI. CONCLUSIONS: The risk of SI has reduced among health professionals since the first peak of the COVID-19 pandemic in China. MI may contribute to prevalent SI, and mental health conditions, especially depressive symptoms, play a significant role as mediators. LIMITATIONS: Cross-sectional design precludes the investigation of casual relationships. The nonrandom sampling method limits the generalization.

The Mediating Effect of Perceived Social Support and Medical Coping Modes Between Psychological Resilience and Meaning in Life in COVID-19 Patients.

Aim: Assess the level of meaning in life of patients with COVID-19, explore the relationship among COVID-19 patients in perceived social support, medical coping modes, psychological resilience and life meaning, and clarify the mediating effect. Methods: Through the convenience sampling method, 144 COVID-19 patients were selected in the year 2021, and surveyed by using general information questionnaire, perceived social support scale (PSSS), medical coping modes questionnaire (MCMQ), meaning in life questionnaire (MLQ) and Connor-Davidson resilience scale (CD-RISC). After the collected data were preprocessed by SPSS, the t-tests, multiple comparison and Pearson coefficient were respectively used for comparative analysis, difference analysis and correlation analysis. Based on the above analysis, the structural equation model of perceived social support, medical coping modes, psychological resilience and meaning in life of COVID-19 patients was established by Amos. Results: COVID-19 patient's score of meaning in life, perceived social support, medical coping modes and psychological resilience are higher than the medium level. The gender and the place of treatment have significant differences in the meaning of life and perceived social support respectively. The patient's sense of life meaning it is closely and positively related to the perceived social support, medical coping modes and psychological resilience. Psychological resilience indirectly affects the sense of life meaning through medical coping modes and perceived social support. Conclusion: The life meaning can be improved by strengthening the perceived social support. The high level of perceived social support was conducive to the patient to think about life from a positive perspective. Family, government, enterprise and others should give patients certain care and warmth, make them feel more support from all walks of life. In addition, the life meaning can also be enhanced through the impact of psychological resilience on medical coping modes. So, care-givers can take some proper psychological interventions to patients.

Association between the overall burden of comorbidity and Ct values among the older patients with Omicron infection: Mediated by inflammation.

Objectives: To investigate the associations between the overall burden of comorbidity, inflammatory indicators in plasma and Ct values among the elderly with COVID-19. Methods: We conducted a retrospective observational study. The results of each nucleic acid test of during hospitalization were obtained. Linear regression models assessed the associations between the overall burden of comorbidity, inflammatory indicators in plasma and Ct values among the elderly. A causal mediation analysis was performed to assess the mediation effects of inflammatory indicators on the association between the overall burden of comorbidity and Ct values. Results: A total of 767 COVID-19 patients aged ≥ 60 years were included between April 2022 and May 2022. Patients with a high burden of comorbidity had significantly lower Ct values of the ORF gene than subjects with a low burden of comorbidity (median, 24.81 VS 26.58, P < 0.05). Linear regression models showed that a high burden of comorbidity was significantly associated with higher inflammatory responses, including white blood cell count, neutrophil count and C-reactive protein. Also, white blood cell count, neutrophil count, C-reactive protein and the overall burden of comorbidity assessed by age-adjusted Charlson comorbidity index were independent risk factors for the Ct values. A mediation analysis detected the mediation effect of white blood cells on the association between the burden of comorbidity and Ct values, with the indirect effect estimates of 0.381 (95% CI: 0.166, 0.632, P < 0.001). Similarly, the indirect effect of C-reactive protein was -0.307 (95% CI: -0.645, -0.064, P = 0.034). White blood cells and C-reactive protein significantly mediated the relationship between the burden of comorbidity and Ct values by 29.56% and 18.13% of the total effect size, respectively. Conclusions: Inflammation mediated the association between the overall burden of comorbidity and Ct values among elderly with COVID-19, which suggests that combined immunomodulatory therapies could reduce the Ct values for such patients with a high burden of comorbidity.

Moderated by personal perception: The preventive relationship between home HIIT dance and depression during the COVID-19 pandemic in China.

Introduction: Lockdowns during the COVID-19 pandemic were believed to greatly increase the risk of depression among isolated residents in both China and in Western countries. How to effectively reduce this risk has become one of the key issues in the field of public mental health. Methods: The present study seeks to examine the preventive relationship between doing home HIIT dance-which became popular during Shanghai's COVID-19 lockdown in 2022-and depression, and how such a preventive relationship has been mediated by different personal perception factors using an online survey with 528 samples. Results: The preventive relationship between doing home HIIT dance and depression was differently mediated by residents' personal perception factors, such as perceived benefits, severity, and self-efficacy, based on the health belief model. Discussion: These results deepen the research on the psychological effects of doing home HIIT dance on preventing depression, especially in the COVID-19 lockdown period, emphasizing the possible moderation effects of different self-perception factors.

Mediating role of resilience between learning engagement and professional identity among nursing interns under COVID-19: A cross-sectional study.

AIM: The aim of the study was to explore the mediating effect of resilience between learning engagement and professional identity of nursing interns. DESIGN: A descriptive, cross-sectional study design. METHODS: An online questionnaire survey was conducted among nursing interns in Fujian Medical University from February 2022 to April 2022 by convenience sampling. The scores of learning engagement, resilience and professional identity were evaluated. The PROCESS Marco in SPSS was used to analyse the mediating effect. RESULTS: A total of 222 senior nursing students participated in the questionnaire survey. Both learning engagement (r = 0.491, p < 0.01) and resilience (r = 0.537, p < 0.01) correlated positively with PI. Resilience is also positively related to PI (r = 0.693, p < 0.01). Also resilience played a partial mediating role in the relationship between learning engagement and professional identity (a*b = b = 0.2451, 95% CI: 0.1543, 0.3581), and its effect accounted for 53.3%.

Depressive symptoms, perceived social support, and anticipated HIV stigma among HIV-negative/unknown men who have sex with men in China during the COVID-19 pandemic: A multicenter online cross-sectional study.

OBJECTIVE: To investigate the prevalence of depressive symptoms among human immunodeficiency virus (HIV)-negative/unknown men who have sex with men (MSM) in China and explore the relationship between perceived social support, anticipated HIV stigma, and depressive symptoms. METHODS: Participants in this study were recruited from a gay social networking app (Blued) in China by convenience sampling from December 16, 2020 to March 1, 2021. Perceived Social Support Questionnaire, Anticipated HIV Stigma Questionnaire, and Center for Epidemiologic Studies Depression Scale were used to measure the social support, anticipated HIV stigma, and depressive symptoms of participants. Confirmatory factor analysis was performed to assess the reliability and validity of the measurement model. Structural equation modeling was employed to evaluate the association of perceived social support, anticipated HIV stigma, and depressive symptoms, as well as the mediation effects. RESULTS: Overall, 47.70% (665/1394) of the participants had depressive symptoms. Perceived social support could have both direct and indirect effects on depressive symptoms with the mediating role of anticipated HIV stigma among HIV-negative/unknown MSM. CONCLUSION: Tailored interventions regarding perceived social support and anticipated HIV stigma, such as group therapy, mutual support groups and mindfulness training, with the involvement of non-governmental or governmental organizations, should be taken into account to reduce depressive symptoms and stigma among HIV-negative/unknown MSM in China.

Diet quality as a mediator in the relationship between perceived stress and depression among family caregivers of patients with chronic illness in Saudi Arabia.

OBJECTIVE: The purpose of this research was to examine the correlation between caregivers' perceived stress and depression and the mediating role of diet in this relationship. METHODS: A cross-sectional survey was performed from January to August 2022 in the Kingdom of Saudi Arabia. Utilizing the Stress Scale, the Anxiety and Depression Scale, the Health Promoting Lifestyle Profile-II questionnaire, and the Patient Health Questionnaire-9, researchers assessed levels of perceived stress, diet quality, and depression. A bootstrap approach and the SPSS PROCESS macro were used to assess the importance of the mediation effect. The target population was family caregivers of patients with chronic illness at Medical City in Saudi Arabia. Researchers surveyed a convenience sample of 127 patients, with 119 providing complete data for a response rate of 93.7%. A significant correlation was found between depression and perceived stress (ß = 0.438, p < 0.001). Diet quality mediated the relationship between depression and perceived stress (ß = 0.187, p = 0.018). The importance of the indirect effect of perceived stress through diet quality was supported by the nonparametric bootstrapping method (95% bootstrap CI = 0.010, 0.080). The indirect effect of diet quality explained 15.8% of the overall variation in depression. CONCLUSIONS: These findings help to clarify the mediating effects of diet quality on the relationship between perceived stress and depression.

Causal effects and functional mechanisms of the Internet on residents' physical fitness-An empirical analysis based on China family panel survey.

Introduction: Physical fitness is an essential part of a healthy lifestyle that concerns the overall health of the nation. Research on the relationship between the Internet and physical fitness has long been caught in the dilemma of "media mobilization" and "media suppression," and previous studies have rarely examined the causal relationship and functional mechanism. Methods: This study selected the data of 23,989 samples successfully followed in all three surveys of the China Family Panel Survey (CFPS) from 2014 to 2018 to explore the correlation and causal inference between the Internet and physical fitness by using the Time Fixed Effects Model and cross-lagged models, respectively; meanwhile, the data of 24,687 samples in CFPS 2020 to examine the functional mechanism of the Internet's effect on residents' physical fitness behavior by the KHB method. Results: We obtained three valuable conclusions as follows: First, there is a significant correlation between the Internet and physical fitness behavior. Second, the Internet use is the cause for the increase in fitness frequency, and there is a rival relationship between Internet duration and fitness time. Third, under regular prevention and control of the COVID-19 epidemic, social capital and health risk perceptions are the functional mechanisms of the Internet influencing fitness behavior, and the mediating effect of psychological health risk perceptions is higher than that of social capital. Discussion: It's necessary to create an intelligent, informative, and digital sports public service system by enriching and optimizing sports media and facilitating the Internet to serve residents' physical fitness better. The new concept of "Internet plus Fitness" will be of great significance in the implementation of the "Healthy China Initiative."

WORKFORCE ANXIETY DUE TO COVID-19 PANDEMIC: THE MEDIATION EFFECT OF PERSONAL FINANCE AMONG PRIVATE LABOR FORCE IN KERALA

The COVID-19 pandemic hit at its worse on the economic and social conditions of the workers across the world. Studying how COVID-19 has created anxiety among the private workforce in Kerala can contribute significant input to the policymakers. The place of this research is also important as Kerala is a state with a strong public health care system and a sizeable number of workers from Kerala are employed in the private sector. The objectives of this study are to measure the direct impact of COVID-19 on workforce anxiety and to analyze the mediation effect of personal finance on workforce anxiety during the COVID-19 pandemic. Principal Component Analysis was done to identify the influential variables under each factor. After ensuring the reliability, validity, and consistency of the questions, the regression analysis was carried out. The statistical software's IBM SPSS Statistics 20 and PROCESS macro 3.5 were used for data analysis. The initial hypothesis (H1) of this study was COVID-19 has a direct relationship with the worker's anxiety. The result of the regression analysis confirmed this assumption. The mediating role of personal finance during the impact of COVID-19 on the worker's anxiety was tested through the bootstrapping method and the indirect effect of COVID-19 on the worker's anxiety through personal finance is also positive and significant. This study is suggesting numerous measures to the policymakers and to the corporate for addressing the worker's anxiety in the social and economic levels. © 2022, Universiti Malaysia Sarawak.

Amplified effect of social vulnerability on health inequality regarding COVID-19 mortality in the USA: the mediating role of vaccination allocation.

BACKGROUND: Vaccination reduces the overall burden of COVID-19, while its allocation procedure may introduce additional health inequality, since populations characterized with certain social vulnerabilities have received less vaccination and been affected more by COVID-19. We used structural equation modeling to quantitatively evaluate the extent to which vaccination disparity would amplify health inequality, where it functioned as a mediator in the effect pathways from social vulnerabilities to COVID-19 mortality. METHODS: We used USA nationwide county (n = 3112, 99% of the total) level data during 2021 in an ecological study design. Theme-specific rankings of social vulnerability index published by CDC (latest data of 2018, including socioeconomic status, household composition & disability, minority status & language, and housing type & transportation) were the exposure variables. Vaccination coverage rate (VCR) during 2021 published by CDC was the mediator variable, while COVID-19 case fatality rate (CFR) during 2021 published by John Hopkinson University, the outcome variable. RESULTS: Greater vulnerabilities in socioeconomic status, household composition & disability, and minority status & language were inversely associated with VCR, together explaining 11.3% of the variance of VCR. Greater vulnerabilities in socioeconomic status and household composition & disability were positively associated with CFR, while VCR was inversely associated with CFR, together explaining 10.4% of the variance of CFR. Our mediation analysis, based on the mid-year data (30th June 2021), found that 37.6% (mediation/total effect, 0.0014/0.0037), 10% (0.0003/0.0030) and 100% (0.0005/0.0005) of the effects in the pathways involving socioeconomic status, household composition & disability and minority status & language, respectively, were mediated by VCR. As a whole, the mediation effect significantly counted for 30.6% of COVID-19 CFR disparity. Such a mediation effect was seen throughout 2021, with proportions ranging from 12 to 32%. CONCLUSIONS: Allocation of COVID-19 vaccination in the USA during 2021 led to additional inequality with respect to COVID-19 mortality. Viable public health interventions should be taken to guarantee an equitable deployment of healthcare recourses across different population groups.

China-Europe freight transportation under the first wave of COVID-19 pandemic and government restriction measures

International freight transportation experienced significant disruptions during the COVID-19 pandemic. The impact of the pandemic and related government restriction measures on international freight transportation is worth analysing for the development of transportation policies and practices in the post-pandemic period, but has received limited attention. To fill the gap, this study applies structural equation models to analyze the impact of the COVID-19 pandemic on the international transportation market and the relationships among the pandemic, government restriction measures, and international transportation market. The impact is also differentiated for different modes of transportation. Results confirm that both demand and supply of international transportation services have been negatively affected by the first wave of the pandemic, with sea transportation being more affected by the reduction of demand and air transportation more by the supply volatility. The government restriction measures are found to play a mediation role, in the way that the impact of the pandemic on the supply of transportation service is suppressed through the government restriction measures. Our findings provide important guidance for transportation industry players and governments in their decision-making process facing with global market shocks such as a pandemic.

Effect of Marriage on Burnout among Healthcare Workers during the COVID-19 Pandemic.

Since the onset of the COVID-19 pandemic, burnout symptoms have been prevalent among healthcare workers. Living with spouses can be complex and was associated with an increased burnout risk during the COVID-19 pandemic. This study investigated the relationship between living with spouses and burnout among healthcare workers during the COVID-19 pandemic. We distributed questionnaires to participants working in a hospital affiliated with a medical university in Taiwan. The questionnaires were the Copenhagen Burnout Inventory, which comprises personal burnout (PB), work-related burnout (WB), and client burnout subscales; the Nordic Musculoskeletal Questionnaire; and information on basic demographic variables, family factors, living habits, work-related factors, and physical health factors. Multiple linear regression and mediation analysis were used. We obtained 1615 (63.81%) valid questionnaires. After analysis revealed that marriage was an independent risk factor for PB; however, the effect of marriage on WB was nonsignificant after controlling for risk factors. Parenthood, less alcohol use, reported sleep duration less than six hours, less overtime, less shift work, and participation in leisure activities with family and friends were found to be mediators between marriage and a lower WB level. In addition, chronic diseases, frequent neck pain, and shoulder pain were suppression factors. In summary, marriage was associated with an increased risk of PB. Married individuals sustain a high WB level because of changes in family roles, living conditions, and work conditions. Overall, helping healthcare workers to maintain well-being in marriage or family living may be effective in decreasing burnout during the COVID-19 pandemic.

Revisit the Effects of Health Literacy on Health Behaviors in the Context of COVID-19: The Mediation Pathways Based on the Health Belief Model.

Background: Emerging research has identified health literacy as an important resource for individual health care and disease prevention. In the context of COVID-19, People with limited HL are less likely to follow preventive measures such as wearing masks, social isolation, or taking the vaccination. However, the pathways of how health literacy affects decision-making have remained unclear. Methods: With a cross-sectional study, a total of 613 responses (mean age is 25.64 ± 6.46 years) were collected. The relationship between health literacy and health behaviors under COVID-19 was examined, and the potential mediation pathways were assessed based on the health belief model. Results: With linear regression, it was found that health literacy has a direct effect on health behaviors and three constructs in the health belief model, i.e., perceived susceptibility, perceived severity, perceived barriers, as well as an indirect effect on health behaviors via increasing perceived barriers related with COVID-19 preventive measures. The results showed that health literacy only goes through the pathway of perceived barriers to influence health behaviors, and the indirect effects via other pathways were not significant. Conclusions: The research addressed the mediation model underlying the effects of health literacy on health behaviors and identified a partial mediation role of perceived barriers. Health literacy could promote individual health behavior by reducing the perceived barriers to forming a healthy lifestyle and making health decisions. Future health promotion interventions increasing people's health literacy should be advocated to promote health initiatives in the whole population.

Mediation effect of perceived social support and resilience between physical disability and depression in acute stroke patients in China: A cross-sectional survey.

BACKGROUND: Physical disability is a cause of depression among acute stroke patients. Although previous studies have shown that physical disability, perceived social support, mental resilience, and post-stroke depression are significantly related, the interaction mechanism remains unclear. METHODS: Convenience sampling was used to recruit participants from a tertiary hospital in Daqing City, Heilongjiang Province, China from October 2020 to May 2021. Participants completed the Barthel Index Rating Scale, Multidimensional Scale of Perceived Social Support, Connor-Davidson Resilience Scale and Zung Self-Rating Depression Scale. We used the PROCESS macro for SPSS to determine the mediating effect of perceived social support and resilience between disability and depression. RESULT: A total of 259 acute stroke patients participated in this study and completed the questionnaire survey. Stroke patients' BI scores was positively correlated with perceived social support (r = 0.26, P < 0.01) and resilience (r = 0.25, P < 0.01), and negatively correlated with depression (r = -0.47, P < 0.01). Perceived social support was positively correlated with resilience (r = 0.55, P < 0.01) and negatively correlated with depression (r = -0.41, P < 0.01). Resilience was negatively correlated with depression (r = -0.43, P < 0.01). Perceived social support and resilience played a mediating role of 10.27% and 5.74% of the total effects of disability and post-stroke depression, respectively. Meanwhile, the chain mediating effect of perceived social support and resilience (7%) was also significant. LIMITATIONS: The cross-sectional study design limited the inference of causal relationships between variables. This study used convenience sampling to select research participants from a single hospital, they were all acute stroke patients from the same region of China. Participants in our study were in high BI status, and thirty of them had a low level of education, which may contribute to the possibility of selection bias. Meanwhile, the low level of education and the poor eye-sight of old people prevents them from completing the questionnaire by themselves. So we collected data in the form of "researcher reading questionnaire items and recording participant responses" for the majority of participants (257 subjects), and only 2 participants completed it independently. Furthermore, the findings of this study may not apply to stroke survivors from other backgrounds. CONCLUSION: This study found that disability can directly predict post-stroke depression, and indirectly predict post-stroke depression through the mediating effect of perceived social support and resilience, and the chain mediating effect of perceived social support-resilience. Therefore, reducing the degree of disability of acute stroke patients and improving their perceived social support and resilience may help prevent post-stroke depression.

Self-Efficacy, Proxy Efficacy, Media Literacy, and Official Media Use in COVID-19 Pandemic in China: A Moderated Mediation Model.

Purpose: COVID-19 pandemic is a significant threat toward the public health. However, the discussion of the mechanism of media literacy's effect in fighting against pandemic is limited. Thus, this study aims to explore the mechanism with a sociocognitive perspective. Methods: A survey was administrated to 420 college students in China. PROCESS macro of SPSS was applied to analyze the data and test the moderated mediation effect. Results: The moderated mediation model of media literacy, proxy efficacy, self-efficacy, and official media use was tested and supported. Official media use was a negative moderator on the association between media literacy and proxy efficacy.

Associations Between Relative Deprivation and Life Satisfaction During the COVID-19 Lockdown: Results of Serial Mediation Analyses.

With the COVID-19 pandemic, life satisfaction among college students has become a key issue at universities and in society. The current study explores the effects of belief in a just world and resilience on the relationship between relative deprivation and life satisfaction. A total of 787 college students from universities in China completed online questionnaires. Results showed that relative deprivation was negatively correlated with life satisfaction. Belief in a just world and resilience separately mediated the relationship between relative deprivation and life satisfaction. Moreover, a serial mediating effect of belief in a just world and resilience was observed between relative deprivation and life satisfaction. These findings suggest that relative deprivation may impair individuals' beliefs in a just world. Moreover, less belief in a just world may lower resilience and consequently decrease life satisfaction. This study enriches the research field of relative deprivation theory in the context of the COVID-19 pandemic, and provides a new interpretation and intervention perspective for improving college students' life satisfaction.
