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.

The Relationship between Rural Left-Behind Children’s Physical Activity and Hope:The Mediating Effects of Perceived Social Support

It has been confirmed in previous studies that there is a positive correlation between physical activity and hope.In this study,rural left-behind children in China was taken as the participants to investigate the impact of physical activity on hope in rural left-behind children and examine the mediating role of perceived social support in the relationship between physical activity and hope.797 valid copies of the questionnaire were collected from China.Pearson correlation coefficient was employed to analyze the relationship between physical activity and hope;SEM and Bootstrap were used to test the mediating effect of perceived social support.The results show that physical activity can not only directly and positively predict the level of hope in rural leftbehind children but can also predict the level of hope through perceived social support;perceived social support plays a mediating role in the relationship between physical activity and hope.These results highlight the necessity to pay more attention to the physical activity of left-behind children and the possibility to improve the level of hope by increasing their physical activity;at the same time,the acquisition of more material,emotional and psychological support from teachers and guardians is more conducive to improving the sense of hope in left-behind children.These findings can deepen the understanding of the sense of hope in left-behind children,and provide new methods for and enlightenments on improving the level of hope in left-behind children.

Interoception mediates the association between social support and sociability in patients with major depressive disorder

BACKGROUND Interoception dysfunction has an important impact on the onset and development of major depressive disorder(MDD).Social support serves as a protective factor against MDD,and sociability also plays a significant role in this condition.These interconnected constructs-social support and sociability-play pivotal roles in MDD.However,no research on the mechanisms underlying the associations be-tween social support and sociability,particularly the potential role of interocep-tion,have been reported.ception,social support,and sociability,respectively.A mediation analysis model for the eight dimensions of intero-ception(noticing,not distracting,not worrying,attention regulation,emotional awareness,self-regulation,body listening,and trust),social support,and sociability were established to evaluate the mediating effects.RESULTS A partial correlation analysis of eight dimensions of the MAIA-2,SSRS,and TSBI scores,with demographic data as control variables,revealed pairwise correlations between the SSRS score and both the MAIA-2 score and TSBI score.In the major depression(MD)group,the SSRS score had a positive direct effect on the TSBI score,while the scores for body listening,emotional awareness,self-regulation,and trust in the MAIA-2C had indirect effects on the TSBI score.In the HC group,the SSRS score had a positive direct effect on the TSBI score,and the scores for attention regulation,emotional awareness,self-regulation,and trust in the MAIA-2C had indirect effects on the TSBI score.The proportion of mediators in the MD group was lower than that in the HC group.CONCLUSION Interoceptive awareness is a mediating factor in the association between social support and sociability in both HCs and depressed patients.Training in interoceptive awareness might not only help improve emotional regulation in depressed patients but also enhance their social skills and support networks.

The Relationship between Mental Health Literacy and Subjective Well-Being of Young and Middle-Aged Residents: Perceived the Mediating Role of Social Support and Its Urban-Rural Differences

This study investigates mental health literacy among young and middle-aged urban and rural residents and the differences in mental health literacy,perceived social support and subjective well-being.From January to February 2022,620 participants(320 rural and 300 urban residents)from three provinces of China were selected by con-venience sampling.A general data questionnaire,mental health literacy scale,perceived social support scale and subjective well-being scale were administered.The mental health literacy scores of urban residents were 3.34±0.57 and those of rural residents were 2.73±0.79.The results of multiple regression analysis showed that the mental health literacy scores of rural residents were more significant than those of urban residents in terms of sex and age,while urban residents’mental health literacy scores were more significant than those of rural resi-dents in terms of monthly income.Mental health literacy,perceived social support and subjective well-being of young and middle-aged urban and rural residents were all positively correlated(P<0.01).While the level of mental health literacy is better among urban residents than rural residents,perceived social support plays a partial mediating role between mental health literacy and subjective well-being of both urban and rural residents,and should be the focus of researchers seeking to improve the level of well-being of residents.

Childhood maltreatment and suicide ideation: A possible mediation of social support

BACKGROUND Existing literature suggests a positive link between childhood maltreatment(CM)and suicide ideation(SI).Nevertheless,whether social support significantly mediates this association remains unknown.AIM To investigate whether social support significantly mediates the association between CM and SI.METHODS In this cross-sectional study of 4732 adolescents from southwest China,we intended to discuss the association between CM and multiple types of SI.In addition,the mediation of major types of social support in this association was also investigated.A self-administrated questionnaire was used to collect the data.A series of multivariate logistic regression models were employed to estimate the association between different types of CM,social support,and SI.The possible mediation of social support in the association between CM and SI was assessed using the path model.RESULTS Based on the cutoffs for subscales of Childhood Trauma Questionnaire,928(19.61%),1269(26.82%),595(12.57%),2337(49.39%),and 3067(64.81%)respondents reported physical abuse,emotional abuse,sexual abuse,physical neglect,and emotional neglect,respectively.Among all the social sources,parental support presented as a significant mediator in the association between emotional maltreatment,both abuse and neglect,and all three types of SI:1-wk,1-year,and lifetime.Parental social support mediated 5.31%and 29.23%,4.80%and 24.50%,and 7.04%and 44.42%of the overall emotional abuse-SI and emotional neglect-SI associations,respectively.CONCLUSION Our findings suggest that improving parental social support might be effective in preventing suicidal risk related to childhood emotional maltreatment in adolescents.

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.
