Geographic proximity to neighborhood resources and depression among older adults in South Korea.

OBJECTIVES: Older adults are closely connected to their neighborhoods and they spend more time there than younger adults. Because their mobility is often impeded by diminished health and functioning, access to neighborhood health and social services is essential for their well-being. This article examines whether geographic proximity to these types of neighborhood resources is associated with depression among older adults in South Korea. METHODS: Data are from A Profile of Older Adults: 2015 which sampled 1,455 community-dwelling individuals ages 60 and older in South Korea. The Patient Health Questionnaire-9 (PHQ-9) was used to assess depression, the outcome. We measured geographic proximity to neighborhood destinations, which included the time it takes the respondent to go to the grocery store, hospital, government office, senior center, social service center, and bus stop. We conducted latent profile analyses (LPA) with a distal outcome using the BCH method to determine whether geographic proximity to neighborhood resources is associated with depression. RESULTS: The LPA identified three distinct subgroups of geographic proximity to neighborhood resources: High Access (10%), Moderate Access (41%), and Low Access (49%). Low Access (b = 3.71, p < .001) and Moderate Access (b = 3.00, p < .001) groups had higher levels of depression compared to those in the High Access group. DISCUSSION: Our findings suggest that access to essential services in one's neighborhood is associated with lower levels of depression, which supports existing evidence that age-friendly community initiatives are important to older adults' psychological well-being.

Felt Age Among Racial/Ethnic Minority Older Adults Attending a Senior Center.

Research shows that felt age among older adults is a good proxy for their current and future physical and mental health. Using both quantitative and qualitative interview data, we examined correlates of and self-reported reasons for felt age among 102 low-socioeconomic status (SES), non-Hispanic Black and Hispanic older adults who were members of a senior activity center. Fewer activities of daily living (ADL)/instrumental activities of daily living (IADL) impairments, more positive affect, and higher self-efficacy were associated with higher odds of feeling younger, while financial stress was associated with lower odds. The most common self-reported reasons for younger felt age were staying active, followed by good health, positive attitudes, exercise/dancing, independence, interpersonal/intimate relationships, faith/spirituality, volunteering, family, driving/traveling, and being of sound mind. Poor health, lack of energy, and limited ability to engage in activities were self-reported reasons for older felt age. Senior center programs that enable older adults to stay active and socially integrated may contribute to their well-being.

Moderating Effects of Community Social Capital on Depression in Later Years of Life: A Latent Interaction Model.

OBJECTIVE: This study tested the stress-buffering model and examined the buffering role of community social capital on late-life depression. METHODS: This study used the data from the second wave of National Social Life, Health, and Aging Project (NSHAP, 2010-2012). In the present study, a total of 2,362 older adults aged 65 and older (Mage = 74.5, SD = 6.69) were included. Latent moderated structural equations model was tested by comparing the main effect model and interaction model. Depression, stress, and community social capital were constructed as latent variables for the analyses. RESULTS: The main effect model was acceptable: χ2 (df = 334) = 1596.4, p = .000; RMSEA = .04 (.038 - .042); CFI = .91; and SRMR = .05. And interaction model was significant (D = 35.0, p < .001). The latent constructs of stress (ß = . 50, p < .001) and community social capital (ß = -.14, p < .001) not only had a direct effect on depression, but their interaction was also significant (ß = -.21, p < .01).). The group with a high level of social capital presented a relatively stable slope in the prediction of stress on depression, suggesting their resilience, while the group with a low level of community social capital demonstrated a steep slope, indicating heighten vulnerability to depression when faced with stress. CONCLUSIONS: The findings support the hypothesis of stress buffering model and identify the protective effects of community social capital on depression of older adults. CLINICAL IMPLICATIONS: Older adults with lower community social capital are particularly vulnerable to depression. The results highlight that practitioners and policymakers should pay more attention to finding ways to enhance community resources to improve older adults' mental health.

The role of social capital in the relationship between physical constraint and mental distress in older adults: a latent interaction model.

OBJECTIVE: Building upon the widely known link between physical and mental health, the present study explored the buffering effects of social capital (indicated by social cohesion, social ties, and safety) in the relationship between physical constraint (indicated by chronic conditions and functional disability) and mental distress (indicated by symptoms of depression and anxiety). METHOD: Using data from 2,264 community-dwelling older adults in the National Social Life, Health, and Aging Project (NSHAP) Wave 2 (Mage = 74.51, SD = 6.67), a latent interaction model was tested. The model of mental distress, including both the main effect of physical constraint and social capital and their latent interaction, presented an excellent fit. RESULTS: The latent constructs of physical constraint (ß = .54, p < .001) and social capital (ß = -.11, p < .01) not only had a direct effect on mental distress, but their interaction was also significant (ß = -.26, p < .001). Subgroup analysis showed that the group with a low level of social capital had a heightened vulnerability to mental distress when faced with physical constraint, whereas the group with a high level of social capital demonstrated resilience. CONCLUSION: Findings call attention to ways to enhance older individuals' social capital in efforts to promote their health and well-being.

Social capital in ethnic communities and mental health: a study of older Korean immigrants.

This study examined how social capital in ethnic communities (e.g., social cohesion, community support, community participation, and negative interaction) influences depressive symptoms of older Korean immigrants. Using survey data from 209 participants in Central Texas (M(age) = 69.6, SD = 7.50), hierarchical regression models of depressive symptoms were examined with the following sets of predictors: (1) demographics, (2) physical health, (3) sociocultural factors, and (4) ethnic community factors. After controlling for the multiple sets of individual-level variables previously known to be important predictors of mental health, ethnic community factors made a substantial contribution. Higher levels of depressive symptoms were observed among individuals who received lower levels of community support (ß = -0.14, p < 0.05), had limited participation in ethnic community events and activities (ß = -0.15, p < 0.05), and reported more frequent negative interactions with ethnic community members (ß = 0.12, p < 0.05). Findings highlight the importance of social capital in ethnic communities and hold implications for improving older ethnic immigrants' mental well-being.

A feasibility study of low-income homebound older adults' participation in an online chronic disease self-management program.

This study explored the feasibility of "Better Choices, Better Health" (BCBH), the online version of Stanford's Chronic Disease Self-Management Program, among 10 low-income homebound older adults with no or limited computer skills, compared with 10 peers with high computer skills. Computer training was provided before and at the beginning of the BCBH workshop. Feasibility data consisted of field notes by a research assistant who provided computer training, participants' weekly logs, and a semi-structured interview with each participant at 4 weeks after the completion of BCBH. All those who initially lacked computer skills were able to participate in BCBH with a few hours of face-to-face demonstration and training. The 4-week postintervention follow-up showed significant improvement in health and self-management outcomes. Aging-service agencies need to introduce BCBH to low-income homebound older adults and utilize their volunteer base to provide computer and Internet skills training for low-income homebound older adults in need of such training.
