Community social capital and cognitive function among older adults in rural north-east China: The moderator role of income

Community- and individual-level social capital and cognitive function among older adults in China: a multilevel analysis

OBJECTIVES

This study aimed to examine (a) the association of cognitive function with community- and with individual-level cognitive and structural social capital, and (b) the cross-level interaction effects of social capital on cognitive function among older adults in China.

METHOD

Quota sampling was used to collect data from 800 respondents living in 20 communities in Tianjin and Shijiazhuang, China, in 2020. Multilevel analysis was conducted to examine the hypotheses.

RESULTS

Individual-level structural social capital was significantly associated with better cognitive function. Furthermore, individual-level cognitive social capital was negatively associated with cognitive function among older adults with low community-level structural social capital, whereas the above association was positive among those with high community-level structural social capital. Following the same pattern, the associations between community-level structural social capital and cognitive function varied by individual-level cognitive social capital.

CONCLUSION

This research highlights the protective role of individual-level structural social capital in Chinese older adults' cognitive function. It also delivers in-depth insights into the varying associations between social capital and cognitive function across different communities or individuals. Future research and practices should focus on cultivating social capital at both levels, and pay attention to the cross-level interactions of social capital.

Social capital, government guidance and contract choice in agricultural land transfer

This study explores the impact of farm households' social capital characteristics and local government policies on the selection of farmland transfer contracts in China's rural industrial revitalization context. Utilizing field research data from 1,979 households in ethnic areas of Hunan Province, this paper constructs an econometric model to assess how farm households' social capital and local governments' involvement in rural industrial revitalization influence farmland transfer contract selections. The findings indicate that, lacking government program support, farmers' social capital significantly affects contract type and duration, but not the rent. Specifically, farmers possessing extensive social capital prefer verbal and short-term contracts (coefficients of 0.525 and 0.643, significant at the 5% level), whereas their influence on rent (coefficient of 2.418, significant at the 5% level) manifests under government program support. These results challenge the conventional theory of farmland transfer contracts and offer substantial empirical support for the development of local government policies in rural industrial revitalization, underlining the critical role of government guidance and social capital in enhancing farmland transfer.

Individual-level community-based social capital and depressive symptoms among older adults in urban China: the moderating effects of socioeconomic status

OBJECTIVES

This study aimed to examine the moderating role of socioeconomic status in the association between community-based social capital-based on individual-level cognitive and structural social capital-and depressive symptoms among older adults in urban China.

METHODS

Data were collected in 2020 through a community survey of 800 respondents aged 60 years and older living in Shijiazhuang and Tianjin. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Multiple-group analyses were conducted to analyze the data.

RESULTS

Measurement models of cognitive social capital and structural social capital were established. Measurement invariance was established across different socioeconomic groups. Additionally, socioeconomic status significantly moderated the association between social capital and depressive symptoms. The association between cognitive social capital and depressive symptoms was statistically significant among respondents with relatively low incomes and high levels of education, whereas the association between structural social capital and depressive symptoms was significant only among those with relatively high incomes.

CONCLUSION

Future social capital policies and interventions should adopt different strategies to provide services to older adults from different socioeconomic backgrounds. Furthermore, educational programs should promote the effects of cognitive social capital on depressive symptoms later in life.

Modeling residents' multidimensional social capital in China's neighborhood renewal projects: SEM and MIMIC approaches

Neighborhood renewal is now an important approach to sustainable urban development in China. However, neighborhood renewal projects are often beset with social problems such as noncooperation from residents, which can be attributed to diverse interests and complex relationships among residents. However, there is little research on resident relations in China and intra-resident conflict. Based on social capital, this study provided a better understanding of resident relationships in neighborhood renewal in China. To this end, we developed a theoretical framework of residents' multidimensional social capital (structural, relational, and cognitive). Then, a survey was conducted to collect data from 590 residents across China who were experiencing or had experienced neighborhood renewal. Structural equation modeling (SEM) and multiple indicators multiple causes (MIMIC) modeling were used. The results revealed positive effects of structural social capital on relational and cognitive social capital, and the mediation role of relational social capital was demonstrated. We also tested the effects of differences in sociodemographic characteristics. Our findings verify the explanatory power of social capital regarding residents' complex relationships in neighborhood renewal in China. Implications for theory and policy are discussed. This study helps to improve our understanding of residents' social systems in neighborhood renewal and provides theoretical support for formulating neighborhood renewal policies in China and abroad.

The Impact of Multidimensional Poverty on Rural Households' Health: From a Perspective of Social Capital and Family Care

Although absolute poverty has been eliminated in rural China, multidimensional poverty has an unstoppable impact on the self-rated health of rural households through multiple dimensions. This study constructed a moderated mediation model with multidimensional poverty as the independent variable to explore the impact on rural households' self-rated health, social capital as a mediating variable, and family care as a moderating variable. We used the survey data of 382 sample out-of-poverty rural households in Jiangxi, China, in 2020. Our results indicated that multidimensional poverty had a detrimental impact on the self-rated health and social capital of rural households, both of which were significant at the 1% level (β = -0.751, t = -4.775, and β = -0.197, t = -7.08). A test of the mediating effect of social capital using the mediation model found the mediating effect accounting for 84.95% of the entire effect of multidimensional poverty on rural households' self-rated health. Further, the interaction term between family care and multidimensional poverty and its beneficial effect on social capital as well as the interaction term between family care and social capital and its negative effect on rural household' self-rated health are both statistically significant at the 1% level (β = 0.558, t = -5.221 and β = -2.100, t = -3.304). It is revealed that multidimensional poverty affects rural households' self-rated health through social capital and that family care moderates the mediating pathway. Family care exacerbates the negative effect of multidimensional poverty on rural households' self-rated health and weakens the beneficial effect of social capital on rural households' self-rated health. The lower (higher) the level of family care, the more significant the positive (negative) effect of social capital on rural households' health. Therefore, rural households should prioritize building social capital and shifting the responsibility for family care. First, through enhancing housing infrastructure and establishing cultural and educational initiatives, households can improve their viability. Second, increasing engagement in group activities will enhance social networks and boost interpersonal connections. Finally, to lessen the stress on family caregivers, building socialized care services can cover the gap in family care.

Community social capital and the health-related quality of life among empty-nest elderly in western China: moderating effect of living arrangements

BACKGROUND

At present, the empty nest phenomenon is becoming more and more serious in the world, especially in China, and its health problems deserve attention. Therefore, the purpose of this study is to explore the impact of community social capital on the health-related quality of life of empty-nest elderly.

METHODS

The study used data collected from a survey study conducted between 2018 and 2019 in Sichuan province, China, with 638 empty-nest elderly meeting our criteria. SF-12 scale and self-made social capital scale were used to evaluate the health-related quality of life and community social capital of empty-nest elderly. Through descriptive statistical analysis, bivariate analysis and hierarchical multiple regression model, this study analyzes the relationship between community social capital and health-related quality of life of empty-nest elderly. Considering the role of living arrangements, this study further uses the simple effect analysis method to explore the moderating role of living arrangements.

RESULTS

After controlling the relevant variables, the cognitive social capital (CSC) of empty-nest elderly had a positive relationship with the physical health summary (PCS) (β = 0.188, p＜0.001) and mental health summary (MCS) (β = 0.205, p＜0.001). No effect of structural social capital on quality of life was found as a result. Living arrangements played a moderation effect on the relationship between CSC and MCS (β=-2.018, p＜0.05). The MCS score of high CSC group (55.516 ± 0.757) was significantly higher than that of low CSC group (49.383 ± 0.722).

CONCLUSION

The results suggest empty-nest elderly has poorer physical health and weaker structural social capital, while the cognitive social capital has a greater positive impact on their quality of life. Targeted interventions to enhance community social capital may be beneficial to improve health status of this vulnerable population.

Perceived neighborhood environment and depressive symptoms among older adults living in Urban China: The mediator role of social capital

An increasing number of studies have focused on the relationship between neighbourhood environment and depressive symptoms among older people. However, the underlying mechanisms are still unclear. This study examined the association between neighbourhood environment and depressive symptoms among older urban Chinese adults and the mediator role of social capital in this association. Using a quota sampling approach, 472 respondents aged 60 years or older were recruited from 23 urban communities of Shanghai, China, in 2020. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale. Social capital was measured by two latent constructs: cognitive social capital (e.g., trust, reciprocity, belongingness) and structural social capital (e.g., memberships, social participation). Perceived physical neighbourhood environment was assessed in terms of health care, security, and public transportation status. Structural equation modelling was conducted to test the study hypotheses. Health care services in the community had a direct effect on depressive symptoms (β = -0.097, p < .05). Cognitive social capital played a mediator role in the relationship between physical neighbourhood environment and depressive symptoms (community health care: β = -0.124, p < .01; community security: β = -0.284, p < .01). The mediator effect of structural social capital in the relationship between physical neighbourhood environment and depressive symptoms was not significant. The findings highlight the role of physical neighbourhood environment in fostering community-based social capital and promoting mental health among older adults in urban China. Policy strategies could focus on improving community health care and security to promote mental health.

Virtual Reality-based Cognitive Intervention for Enhancing Executive Functions in Community-dwelling Older Adults

With the rapid growth of the older population globally, it is anticipated that age-related cognitive decline in the prodromal phase and more severe pathological decline will increase. Moreover, currently, no effective treatment options for the disease exist. Thus, early and timely prevention actions are promising and prior strategies to preserve cognitive functions by preventing symptomatology from increasing the age-related deterioration of the functions in healthy older adults. This study aims to develop the virtual reality-based cognitive intervention for enhancing executive functions (EFs) and examine the EFs after training with the virtual reality-based cognitive intervention in community-dwelling older adults. Following inclusion/exclusion criteria, 60 community-dwelling older adults aged 60-69 years were involved in the study and randomly divided into passive control and experimental groups. Eight 60 min virtual reality-based cognitive intervention sessions were held twice a week and lasted for 1 month. The EFs (i.e., inhibition, updating, and shifting) of the participants were assessed by using standardized computerized tasks, i.e., Go/NoGo, forward and backward digit span, and Berg's card sorting tasks. Additionally, a repeated-measure ANCOVA and effect sizes were applied to investigate the effects of the developed intervention. The virtual reality-based intervention significantly improved the EFs of older adults in the experimental group. Specifically, the magnitudes of enhancement were observed for inhibitory as indexed by the response time, F(1) = 6.95, p < .05, η_p² = .11, updating as represented by the memory span, F(1) = 12.09, p < .01, η_p² = .18, and the response time, F(1) = 4.46, p = .04, η_p² = .07, and shifting abilities as indexed by the percentage of correct responses, F(1) = 5.30, p = .03, η_p² = .09, respectively. The results indicated that the simultaneous combined cognitive-motor control as embedded in the virtual-based intervention is safe and effective in enhancing EFs in older adults without cognitive impairment. Nevertheless, further studies are required to investigate the benefits of these enhancements to motor functions and emotional aspects relating to daily living and the well-being of older populations in communities.

Community Social Capital, Family Social Capital, and Self-Rated Health among Older Rural Chinese Adults: Empirical Evidence from Rural Northeastern China

This study investigated the relationships among community social capital, family social capital, and self-rated health of older adults in rural China. Data came from a community survey in Jilin Province, China, in 2019. Using a quota sampling method, 458 respondents aged 60 years or older were recruited. Two-step structural equation modeling was adopted to examine the proposed hypotheses. The relationships between community-based structural social capital, family social capital and self-rated health were statistically significant, whereas the relationship between community-based cognitive social capital and self-rated health was statistically nonsignificant. In order to enhance healthy aging, social capital policies and interventions should be developed to promote not only family social capital indicators (e.g., quality of family relationship and support) but also older adults' structural social capital indicators (e.g., social participation and volunteering) in rural Chinese contexts.
