Scarcity and Mental Health—Multiple Mediators of Sleep Quality and Life Satisfaction

Background:In the current social environment,scarcity,as a universally present objective state,profoundly impacts individuals’decision-making and health through the subjective feeling it induces,known as a“scarcity mindset.”Particularly,the feeling of scarcity related to money and sleep time is not only widespread but also directly linked to an individual’s mental health.Purpose:This study aims to delve into the relationship between the feeling of scarcity and mental health,with a specific focus on the relationship between the feeling of money scarcity or sleep time scarcity and mental health,as well as the role of sleep quality or life satisfaction in this relationship.Procedure:We determined the sampling quotas based on the population and economic development levels of each province in the“China Statistical Yearbook(2021)”(National Bureau of Statistics,2021).Participants were selected using the Probability Proportional to Size(PPS)sampling method.Data was collected by distributing online questionnaires to participants,and the relationships between the main variables were explored using structural equation modeling.Results:1.In China,the feeling of sleep time scarcity is stronger than the feeling of money scarcity among the public.2.The feeling of money scarcity is positively correlated with depression and anxiety,whereas the feeling of sleep time scarcity is only positively correlated with depression.3.The feeling of scarcity mainly leads to depression and self-denial through reducing life satisfaction,and it leads to anxiety through reducing sleep quality.Conclusion:The feeling of scarcity in money and sleep time is related to different dimensions of mental health.Therefore,reasonably planning financial allocation and ensuring an adequate amount of sleep can reduce the sense of scarcity,thereby improving mental health.Additionally,improving sleep quality and increasing life satisfaction can alleviate the adverse effects of scarcity on mental health.

Resilience provides mediating effect of resilience between fear of progression and sleep quality in patients with hematological malignancies

BACKGROUND Hematological tumors are common malignant tumors,with high morbidity and mortality rates.Most patients with hematological malignancies develop sleep disorders that seriously affect their life and health because of acute onset of disease,rapid progression,high recurrence rates,complex treatment methods,and treatment costs.AIM To explore the mediating effect of resilience on fear of disease progression and sleep quality in patients with hematological malignancies.METHODS A cross-sectional analysis of 100 patients with hematological malignancies,treated in the First Affiliated Hospital of Jinzhou Medical University between August 2022 and August 2023,was conducted.Patients were assessed using a general data survey,a simplified scale for the fear of progression(FoP)of disease,a resilience scale,and the Pittsburgh Sleep Quality Index.Statistical analysis was conducted to determine the relationship between various patient characteristics and FoP,resilience,and sleep quality.Spearman’s correlation analysis was used to examine the correlations between mental resilience,FoP,and sleep quality.RESULTS The total FoP score mean value in patients with hematological malignancies was 38.09±5.16;the total resilience score mean value was 40.73±7.04;and the Pittsburgh Sleep Quality Index score mean value was 10.72±1.90.FoP,resilience,and sleep quality of the patients were associated with family per capita monthly income and patient education level(P<0.05).Spearman correlation analysis revealed that FoP was negatively correlated with resilience and sleep quality scores(r=-0.560,-0.537,P<0.01),respectively,and resilience was significantly associated with sleep quality scores(r=0.688,P<0.01).Mediation analysis showed that the mediating effect of resilience between FoP and sleep quality in patients with hematological malignancies was-0.100 and accounted for 50.51%of the total effect.This indicated that FoP directly and indirectly affected sleep quality through the mesomeric effect of resilience.CONCLUSION Resilience is an intermediary variable between FoP and sleep quality in patients with hematological malignancies.Medical staff should evaluate and follow-up FoP and resilience to implement measures to improve sleep quality.

Mediating role of social support in dysphoria,despondency,and quality of life in patients undergoing maintenance hemodialysis

BACKGROUND Dysphoria and despondency are prevalent psychological issues in patients undergoing Maintenance Hemodialysis(MHD)that significantly affect their quality of life(QOL).High levels of social support can significantly improve the physical and mental well-being of patients undergoing MHD.Currently,there is limited research on how social support mediates the relationship between dysphoria,despondency,and overall QOL in patients undergoing MHD.It is imperative to investigate this mediating effect to mitigate dysphoria and despondency in patients undergoing MHD,ultimately enhancing their overall QOL.AIM To investigate the mediating role of social support in relationships between dysphoria,despondency,and QOL among patients undergoing MHD.METHODS Participants comprised 289 patients undergoing MHD,who were selected using a random sampling approach.The Social Support Rating Scale,Self-Rating Anxiety Scale,Self-Rating Depression Scale,and QOL Scale were administered.Correlation analysis was performed to examine the associations between social support,dysphoria,despondency,and QOL in patients undergoing MHD.To assess the mediating impact of social support on dysphoria,despondency,and QOL in patients undergoing MHD,a bootstrap method was applied.RESULTS Significant correlations among social support,dysphoria,despondency,and quality in patients undergoing MHD were observed(all P<0.01).Dysphoria and despondency negatively correlated with social support and QOL(P<0.01).Dysphoria and despondency had negative predictive impacts on the QOL of patients undergoing MHD(P<0.05).The direct effect of dysphoria on QOL was statistically significant(P<0.05).Social support mediated the relationship between dysphoria and QOL,and this mediating effect was significant(P<0.05).Similarly,the direct effect of despondency on QOL was significant(P<0.05).Moreover,social support played a mediating role between despondency and QOL,with a significant mediating effect(P<0.05).CONCLUSION These findings suggest that social support plays a significant mediating role in the relationship between dysphoria,despondency,and QOL in patients undergoing MHD.

Mediating effect of mindfulness level on the relationship between marital quality and postpartum depression among primiparas

BACKGROUND Postpartum depression refers to a depressive episode or depressive symptoms up to 12 mo after delivery.Trait mindfulness has presented a protective factor for postpartum depressive symptoms and proved efficient in improving relationship satisfaction among couples.AIM To investigate the correlations among mindfulness,marital quality,anxiety,and depression in a large city in western China during the post-corona virus infectious disease-2019 era and determine whether trait mindfulness mediates the relationship between marital quality and postpartum anxiety and depression among primiparas.METHODS A cross-sectional study was conducted.The self-administered questionnaire was submitted online through smartphones.The levels of mindfulness,anxiety,depression,and marital quality were respectively investigated by the mindful attention awareness scale(MAAS),the self-rating anxiety scale(SAS),the selfrating depression scale(SDS),and the marriage perception scale(MPS)in these enrolled Han and Tujia primiparas.RESULTS No statistical significance was observed in the prevalence of postpartum anxiety and depression,nor scores of MAAS and MPS-Total in different regions or ethnicities(P>0.05).However,MPSMarital interaction(P<0.05),MPS-Family relationship(MPS-FR)(P<0.01),and MPS-Marital conflict(MPS-MC)(P<0.01)scores of urban primiparas were higher than those of rural primiparas.The MPS-MC score of Han primiparas was higher than that of Tujia primiparas(P<0.05).Negative correlations were observed between MAAS and SAS(r=-0.457,P<0.01),and MAAS and SDS(r=-0.439,P<0.01).SAS has revealed a highly positive correlation with SDS(r=0.720,P<0.01)and a weak negative correlation with MPS(r=-0.200,P<0.05).Besides,a weak negative correlation was observed between MAAS and MPS-MC(r=-0.184,P<0.05),and a weak positive correlation was noticed between SAS and MPS-MC(r=-0.225,P<0.01).Mediation analysis demonstrated a full mediation effect of mindfulness level on the relationship between MPS-FR and postpartum anxiety(P<0.05,95%CI:-0.384 to 0.033),MPS-MC and postpartum anxiety(P<0.01,95%CI:0.027-0.193),MPS-FR and postpartum depression(P<0.05,95%CI:-0.365 to 0.031),and MPS-MC and postpartum depression(P<0.01,95%CI:0.022-0.206).CONCLUSION Mindfulness demonstrates negative correlations with marital conflict,postpartum anxiety and depression,and it may have cross-ethnic and trans-regional characteristics.Although the mindfulness levels have revealed no significant mediating effect between the total score of marital quality and postpartum depression in this study,it demonstrates a full mediation effect on the relationships between family relationships,marital conflict,and postpartum anxiety and depression.

The mediatory role of water quality on the association between extreme precipitation events and infectious diarrhea in the Yangtze River Basin,China

Extreme precipitation is exacerbating the burden of infectious diarrhea in the context of climate change,it is necessary to identify the critical and easy-to-intervene intermediate factors for public health strategies.Water quality may be the most important mediator,while relevant empirical evidence is limited.This study aimed to examine the role of water quality in the process of infectious diarrhea caused by extreme precipitation.Weekly infectious diarrhea cases,meteorological factors and water quality data in Yangtze River Basin in China between October 29,2007 to February 19,2017 were obtained.Two-stage statistical models were used to estimate city-specific extreme precipitation,water quality and infectious diarrhea relationships that were pooled to derive regional estimates.A causal mediation analysis was used to assess the mediation effect of water quality.In Yangtze River Basin,extreme precipitation events had a significant impact on infectious diarrhea(Incidence Rate Ratios[IRR]:1.027,95%Confidence Interval[CI]:1.013~1.041).After extreme precipitation events,the dissolved oxygen(DO)in surface water decreased(-0.123 mg/L,95%CI:-0.159 mg/L~-0.086 mg/L),while the un-ionized ammonia(NH(3)-N)increased(0.004 mg/L,95%CI:0.001 mg/L~0.006 mg/L).The combined overall effect of DO and NH(3)-N on infectious diarrhea showed that both low and high concentrations were associated with an increased risk of infectious diarrhea.The causal mediation analysis showed that the mediation proportion of the two water quality indexes(DO and NH(3)-N)is 70.54%(P<0.001).To reduce the health effects of extreme precipitation,in contrast to current population-oriented health strategies,those that take into account more direct and easy-to-intervene water quality indicators should be encouraged by future policies.

Institutional Correction of Mediation under the View of Transformation:Taking the People’s Mediation as an Example

Under the dual driven forces of soaring disputes and national policy,the dispute resolution ecosystem of China showed the mediation centralism,and the revival of mediation presented the characteristics of adversary system.In order to comply with the modern rule of law system,the traditional mediation is incorporated into the modern legal system through the three-level transformation of"discipline of laws","introduction of procedures"and"specialized cultivation",which was promoted by the popularity of social governance,the input of the idea of diversified solutions and the pragmatic impetus under the pressure of social transformation.The mediation movement has the characteristics of both consciousness of pragmatism and the initial legalization,but will also face the mediation disorder.The remodeling of mediation must be rooted in systematization and modernization.Its development trend includes expansion of fields,symbiosis of autonomy and specialization,and mandatory introduction.

Community Workers’Social Support and Sleep Quality during the Coronavirus Disease 2019(COVID-19):A Moderated Mediation Model

To explore the relationship between social support and sleep quality of community workers in Wuhan during the coronavirus disease 2019(the COVID-19 infection epidemic),this research constructed a mediating effect model to explore the mediating psychological mechanism of social support influencing sleep quality of front-line community workers.A total of 500 front-line community workers in Wuhan were investigated.We used the perceived social support scale(PSSS),the Connor-Davidson Resilience Scale(CD-RISC),the perceived stress scale(PSS),and the Pittsburgh sleep quality index(PSQI)to measure social support,psychological resilience,perceived stress and sleep quality.Specifically,the higher the PSQI,the worse the sleep quality.Pearson correlation structural equation model was used to analyze the relationship between these factors.The results showed that:(1)There was a significant negative correlation between social support,psychological resilience,and perceived stress of community workers and PSQI,that means,the higher the level of social support,psychological resilience,and perceived stress,the higher the sleep quality.(2)Social support positively predicted psychological resilience and perceived stress,and perceived stress negatively predicted PSQI.(3)Social support can affect sleep quality through the mediating role of psychological resilience and perceived stress,and the mediating role includes two paths:the single mediating role of perceived stress and the chain mediating role of psychological resilience-perceived stress.(4)Gender moderates the relation-ship between social support and perceived stress,and the influence of social support on perceived stress of women is higher than that of men.Gender moderates the relationship between psychological resilience and PSQI,and only women’s psychological resilience had a negatively predictive effect on PSQI,while men did not,which means that psychological resilience of female frontline community workers can positively predict sleep quality.This research reveals the relationship between social support and sleep quality and its mechanism and verifies that social support can indirectly affect physical health through psychological resilience and perceived stress.It provides reference suggestions and intervention guidance for improving the sleep quality of community workers.

Relationship between depression,smartphone addiction,and sleep among Chinese engineering students during the COVID-19 pandemic

BACKGROUND Existing research has demonstrated that depression is positively related to smartphone addiction, but the role of sleep has not been discussed thoroughly, especially among engineering undergraduates affected by the coronavirus disease 2019 pandemic.AIM To evaluate sleep as a mediator of the association between smartphone addiction and depression among engineering undergraduates.METHODS Using a multistage stratified random sampling method, a cross-sectional survey was conducted among 692 engineering undergraduates from a top engineering university in China, and data were collected by self-reported electronic questionnaires. The data included demographic characteristics, such as age, gender, the Smartphone Addiction Scale-Short Version(SAS-SV), the 9-item Patient Health Questionnaire, and the Pittsburgh Sleep Quality Index. Pearson correlation and multiple linear regression analyses were used to examine the association between smartphone addiction and depression, while structural equation models were established to evaluate the possible mediating role of sleep.RESULTS Based on the cutoffs of the SAS-SV, the rate of smartphone addiction was 63.58 percent, with 56.21 percent for women and 65.68 percent for men, among 692 engineering students. The prevalence of depression among students was 14.16 percent, with 17.65 percent for women, and 13.18 percent for men. Smartphone addiction was positively correlated with depression, and sleep played a significant mediating effect between the two, accounting for 42.22 percent of the total effect. In addition, sleep latency, sleep disturbances, and daytime dysfunction significantly mediated the relationship between depression and smartphone addiction. The mediating effect of sleep latency was 0.014 [P < 0.01;95% confidence interval(CI): 0.006-0.027], the mediating effect of sleep disturbances was 0.022(P < 0.01;95%CI: 0.011-0.040), and the mediating effect of daytime dysfunction was 0.040(P < 0.01;95%CI: 0.024-0.059). The influence of sleep latency, sleep disturbances, and daytime dysfunction accounted for 18.42%, 28.95%, and 52.63% of the total mediating effect, respectively.CONCLUSION The results of the study suggest that reducing excessive smartphone use and improving sleep quality can help alleviate depression.

The Influence of the Urban-Rural Income Disparity on the Industrial Structure—Taking the Yangtze River Delta Region as an Example

In this paper, the effect of the mediation effect is mainly used to test and analyze the regression model, and most scholars have studied the impact of the modernization of the industrial structure on the income gap. However, this paper is from another perspective, based on the social background of high-quality development, the main study is the impact mechanism of urban and rural income gap on the industrial structure, taking the Yangtze River Delta as the main research object, and specifically selecting 22 central cities in the Yangtze River Delta region, which is also one of the highlights of this study. The regression model is constructed by using the intermediary effect, and the four intermediary variables of fiscal expenditure (M1), fixed asset investment (M2), number of patent applications (M3), and total import and export (M4) are selected, which represent the role of the government, fixed asset investment, scientific and technological level and opening-up level, and study and analyze the inherent influence mechanism between each variable. Before doing specific research, I consulted the papers and literature of many other outstanding scholars, among which Cheng Yuhong and Cheng Chi’s “The Influence Mechanism of industrial structure of urban and rural income gap” [1] has great reference value for this paper. According to the research results, under the background of high-quality development in the Yangtze River Delta region, the expansion of the income gap between urban and rural areas will inhibit the upgrading of the industrial structure, so it is necessary to focus on building a new type of urbanization, accelerating the construction of an urban innovation system, optimizing the rural employment structure to narrow the income gap between urban and rural areas, and providing impetus for the continuous upgrading of the industrial structure.
