Relationship of Living and Eating Arrangements to Mental Distress Among Older Korean Immigrants: Gender Difference in the Mediating Role of Loneliness.

This study examined how different living/eating arrangements were associated with loneliness and depressive symptoms among older Korean immigrants. We examined gender differences considering: (1) patterns of living/eating arrangements and their relations with loneliness and mental distress and (2) indirect effect of living/eating arrangements on mental distress through feeling lonely. Data were drawn from the Study of Older Korean Americans that surveyed older; Korean immigrants during 2017-2018 (N = 2150). Living/eating arrangements were classified in the combination of four categores. Using the PROCESS macro, we tested gender differences in the mediation effect of loneliness on the relationship between living/eating arrangements and mental distress while controlling for background/health characteristics and social connectedness-related variables. The mediating role of loneliness was manifested differentially between men and women. By administering simple measures of living/eating arrangements, practitioners could potentially identify key targets to improve social and mental well-being, particularly among older immigrants with limited resources.

Perceived racial discrimination and mental distress in older Korean Americans: the moderating role of ethnic resources.

OBJECTIVES: To examine associations among perceived racial discrimination, ethnic resources, and mental distress in older Korean Americans. Ethnic resources included ethnic identity (how closely individuals identify themselves with other members of the same ethnic background) and sense of community (individuals' feelings of belonging to their ethnic group). We examined the direct effect of perceived racial discrimination and these ethnic resources, as well as their interactions, hypothesizing that mental distress associated with perceived racial discrimination would be reduced by ethnic resources. DESIGN: Using survey data from the Study of Older Korean Americans (N = 2,150), linear regression models of mental distress were examined for direct and interactive roles of perceived racial discrimination and ethnic resources. RESULTS: Mental distress was directly associated with perceived racial discrimination (B = 1.90, SE = .20, p < .001), ethnic identity (B = -.41, SE = .13, p < .01), and sense of community (B = -.45, SE = .12, p < .001). Perceived racial discrimination interacted significantly with sense of community (B = -1.86, SE = .28, p < .001). Subgroup analyses suggested that in the context of experiencing racial discrimination, a high sense of community can serve as a buffer against mental distress. CONCLUSIONS: Ethnic resources are a benefit in coping with experiences of discrimination. The moderating role of sense of community suggests the value of fostering social capital in ethnic communities to protect and promote older immigrants' mental health.

Factors Associated With Dietary Risks in Older Korean Americans.

Given the importance of healthy eating in the later years of life, the present study examined factors associated with dietary risks in older Korean Americans. We hypothesized that dietary risks would be associated with sociodemographic disadvantages, adverse health conditions, and limited sociocultural resources. Dietary risks were assessed with a scale covering five behavioral and situational risk factors (eating alone, skipping meals, functional challenges, oral health problems, and financial difficulties). Analyses of the data from the Study of Older Korean Americans (N = 2,150) showed that the sample on average had 1.13 risks (SD = 1.31), eating alone having the highest frequency (35.6%). Supporting the hypothesis, higher levels of dietary risks were found in individuals with sociodemographic disadvantages, poorer physical and mental health status, smaller social networks, and lower acculturation. Findings suggest concerted efforts to promote dietary behaviors and call attention to older immigrants who are socially and culturally isolated.

Older Korean Americans' Perceived Burdensomeness to Their Healthcare Partners: An Egocentric Network Assessment.

Objectives: The objective is to examine how older Korean Americans' perceived burdensomeness to their healthcare partners is associated with the characteristics of older adult participants (egos) and their healthcare partners (alters). Methods:Surveys of 2150 participants in the Study of Older Korean Americans provided ego data. Participants were also asked to list up to three individuals whom they usually asked for help on health-related matters or healthcare use, which generated 3402 alters. Multilevel modeling was conducted to examine the role of the characteristics of egos and alters, as well as their cross-level interactions. Results: Perceived burdensomeness was negatively associated with English-speaking ability and residence in a low Korean density area. Perceived burden was also lowered when emotional support was received from the alters, and this pattern was pronounced among those with multi-comorbidity. Discussion: By identifying older immigrants prone to the sense of burdensomeness, the study suggests strategies to promote their health and healthcare use.

The Mental Health Benefit of Friend Networks in Older Korean Americans: The Conditioning Effect of Family Type.

OBJECTIVES: We identified types of family relationships of older Korean Americans and examined how the mental health benefit of friend networks might be conditioned by family type. METHODS: Data were from 2,070 participants in the Study of Older Korean Americans, a multistate survey of Korean immigrants aged 60 and older (Mage = 73.3, standard deviation [SD] = 8.01). To identify family types, latent profile analysis (LPA) was performed with marital status, living arrangement, family network, positive and negative interactions with family members, and family mistreatment. Linear regression models examined how mental distress was associated with friend networks and family types, as well as their interactions. RESULTS: LPA identified 5 family types: close-knit, intimate but distant, detached, connected but dysfunctional, and dysfunctional. Greater distress was associated with smaller friend networks and belonging to the detached, connected but dysfunctional, and dysfunctional family types in comparison to the close-knit type. The interaction model showed that people in the connected but dysfunctional and dysfunctional groups had a stronger association between friend networks and mental distress than the counterparts in the close-knit group. DISCUSSION: We not only confirmed the health-promoting role of friend networks and the value of a close-knit family but also found that the benefit of friend networks was pronounced when quality of the family relationship was impaired. Our findings called renewed attention to older immigrants' social convoys of family and friends, suggesting that the enhancement of friend networks could be particularly advantageous for older immigrants with dysfunctional family relationships.

Relationship of social isolation with mental distress among older Korean Americans: The moderating role of social cohesion.

Social isolation has been associated with poor mental health outcomes, particularly for older immigrants who do not have a protective social environment. The purpose of this study was to investigate the relationship of social isolation (living alone, marginal family ties and marginal friend ties) with mental distress and to examine the moderating role of social cohesion (family cohesion and community cohesion). We hypothesised that social isolation and social cohesion would be directly associated with mental distress and that social cohesion would buffer the influence of social isolation on mental distress. Data were drawn from the Study of Older Korean Americans (SOKA), which included 2150 older Korean Americans aged 60 or over in multiple areas, collected during 2017-2018. A series of hierarchical regression models of mental distress examined the direct and interactive role of social isolation and social cohesion. Approximately one-third of the sample lived alone, 20% had marginal family ties and 27% had marginal friend ties. All three indicators of social isolation had a significant direct effect on mental health; however, living alone lost its statistical significance with the inclusion of social cohesion variables. Both indicators of family and community cohesion were significantly associated with lower levels of mental distress. In addition, family cohesion buffered the negative effects of marginal ties to family and friends on mental distress. The significant role of a positive social environment must be considered when addressing the needs of older immigrants who are socially isolated.

Social isolation in Asian Americans: risks associated with socio-demographic, health, and immigration factors.

OBJECTIVES: The present study examined the factors associated with social isolation in Asian Americans. Three types of social isolation (social isolation from family, social isolation from friends, and overall social isolation), identified by the Lubben Social Network Scale-6, were examined with a sample of Asian Americans representing diverse ethnic groups (Chinese, Asian Indian, Korean, Vietnamese, Filipino, and other Asians) and a broad age range (18-98). DESIGN: Using data from the 2015 Asian American Quality of Life Survey (N = 2609), logistic regression models examined how each type of social isolation was predicted by sociodemographic (age, gender, ethnic origin, marital status, education, and perceived financial status), health-related (chronic medical conditions and self-rated health), and immigration-related (proportion of life in the United States and English proficiency) variables. RESULTS: The percentage of the sample that fell into the category of social isolation from family, social isolation from friends, and overall isolation ranged from 18.2% to 19.3%. At 36% in the friend category and 33% in the overall category, the Vietnamese sample showed a heightened risk of social isolation. Regression analyses indicated that, for both family and friend categories, individuals who were in the middle-aged group (40-59 years old) and who had limited English proficiency demonstrated higher odds of being isolated. Reflecting relational differences in family and friend networks, the risk associated with unmarried status was specific to social isolation from family, whereas having unmet financial needs was only associated with social isolation from friends. CONCLUSIONS: The study findings expand our understanding of the multiple domains of social isolation in an understudied population and emphasize the importance of developing prevention and intervention programs to foster social connectedness among Asian Americans. Our findings on risk factors and ethnic variations help identify the groups to be prioritized in intervention efforts and suggest ways to approach them.

The Relations of Social Network Types With Mental Distress Among Older Korean Americans: The Interactive Role of Living Arrangement.

The purpose of this study is to identify social network types in older Korean Americans and to examine their direct associations, as well as interactions with living arrangement, on mental distress. Drawn from the Study of Older Korean Americans (SOKA), participants were aged 60 or over and lived in five states. Analyses included 2,140 cases surveyed during 2017-2018. To identify social network types, latent profile analyses were conducted using 10 network-related criterion variables. A model with five social network types was identified as best fit. The groups were labeled as diverse, moderately diverse, family deficit, friend deficit, and restricted. As hypothesized, greater mental distress was associated with belonging to more deprived networks such as family deficit and restricted groups. Interaction effects also suggest that members of the restricted group were more distressed when they lived alone than when they lived with others. Implications based on the results are discussed.

Performance of an Abbreviated Lubben Social Network Scale (LSNS-6) in Three Ethnic Groups of Older Asian Americans.

BACKGROUND AND OBJECTIVES: The present study examined the measurement quality and performance of an abbreviated Lubben Social Network Scale (LSNS-6) in three ethnic groups (Chinese, Koreans, and Vietnamese) of older Asian Americans, addressing both within- and cross-group validations. RESEARCH DESIGN AND METHODS: We selected 605 participants aged 50 or older (242 Chinese, 150 Koreans, and 213 Vietnamese) from the 2015 Asian American Quality of Life survey, conducted with self-identified Asian Americans aged 18 or above living in central Texas. We analyzed LSNS-6 data on measurement qualities (internal consistency and corrected item-total correlation), dimensionality (exploratory and confirmatory factor analyses), and correlations with other indicators. RESULTS: LSNS-6 showed very good internal consistency in each ethnic group, and the two-factor structure of family and friends were invariant across the groups. The items on friends demonstrated greater homogeneity than those on family and emerged as a first factor. Both subscale and total scores of LSNS-6 were associated in expected directions with the social and health indicators considered. DISCUSSION AND IMPLICATIONS: The findings confirm the measurement qualities of LSNS-6 within each group and provide support for measurement invariance across the groups. While the observed difference in family and friend networks warrants further investigation, LSNS-6 serves as a viable option for the assessment of social networks. When using LSNS-6 with older Asian Americans, it is highly recommended to use the family/friend subscales in consideration of cultural and immigration contexts.

Bridging Potential in Friend Networks and Cognitive Function in Older Korean Americans.

OBJECTIVES: To examine the associates of bridging potential in networks of friends and its impact on cognitive function in older Korean Americans. METHODS: Data came from 308 participants in Central Florida who were part of the Study of Older Korean Americans (SOKA). Using data from a name generator of three close friends in local Korean communities, non-overlapping networks were quantified for bridging potential. Linear regression models for bridging potential and cognitive function were examined. RESULTS: Bridging potential was greater among those with stronger social ties with friends in general and higher levels of activity engagement. The direct benefit of bridging potential on cognitive function was also confirmed. In addition, bridging potential was found to mediate the effect of social ties with friends on cognitive function. DISCUSSION: Findings underscore the interconnectedness of older immigrants' social and cognitive function and shed light on interventions.

Health risks posed by social and linguistic isolation in older Korean Americans.

OBJECTIVES: Inspired by the notion of double jeopardy positing the dual disadvantage in the coexistence of different sources of vulnerability, the present study examined health risks posed by social and linguistic isolation in older Korean Americans. DESIGN: A cross-sectional study, using a four-cell classification to compare isolation types (no isolation, social isolation only, linguistic isolation only, and dual isolation) and to examine their impacts on physical (self-rated health), mental (mental distress), and cognitive (cognitive performance) health. SETTING AND PARTICIPANTS: Data are from the Study of Older Korean Americans survey of Korean immigrants aged 60 or older (n = 2032), conducted in five states in the United States (California, New York, Texas, Hawaii, and Florida). MEASUREMENT: Social isolation was indexed by the Lubben Social Network Scale-6; linguistic isolation, by a question on English-speaking ability. Physical, mental, and cognitive health were indicated by a single-item self-rating of health, the Kessler Psychological Distress Scale 6, and the Mini-Mental State Examination, respectively. RESULTS: The dual-isolation group exhibited notable sociodemographic and health disadvantages. The odds of having fair/poor health, mental distress, and cognitive impairment were 2.21-3.17 times higher in the dual-isolation group than in the no-isolation group. CONCLUSION: Our findings confirm that both social relationships and language proficiency are key elements for older immigrants' social connectedness and integration, the deprivation of which puts them at heightened risk in multiple dimensions of health.

Discordance Between Subjective and Objective Cognitive Function in Older Korean Americans.

Objectives: To examine predictors of membership in discordant groups identified by subjective and objective measures of cognitive function. Methods: Participants in the Study of Older Korean Americans (N = 2046) were classified according to their subjective cognitive ratings (excellent/very good/good vs. fair/poor) and Mini-Mental State Examination scores (normal cognition vs. cognitive impairment), yielding two discordant groups: (1) positive ratings but cognitive impairment and (2) negative ratings but normal cognition. Logistic regression models examined how the discordant group membership was associated with personal resources. Results: Among those with positive cognitive ratings, the odds of belonging to the discordant group were associated with low personal resources (advanced age and lower levels of education, acculturation, and knowledge about Alzheimer's disease). However, an opposite pattern was observed among those with negative ratings. Discussion: The pattern of discordance suggests ways to promote early detection of cognitive impairment and close the gap in cognitive health care.

Cognitive health risks posed by social isolation and loneliness in older Korean Americans.

BACKGROUND: This study examines associations among social isolation, loneliness, and cognitive health risks in older Korean Americans, focusing on the mediating role of loneliness in the relationship between social isolation and objective and subjective measures of cognitive impairment. METHODS: Data are from 2061 participants in the Study of Older Korean Americans, a multi-state survey of Korean immigrants age 60 and older (Mage = 73.2, SD = 7.93). Social isolation was indexed with the Lubben Social Network Scale- 6; loneliness, with the short-form UCLA Loneliness Scale. Objective and subjective measures of cognitive impairment included the Mini-Mental State Examination and a single-item self-rating of cognitive health. RESULTS: In the logistic regression model for objective cognitive impairment, social isolation was significantly associated, but loneliness was not. In the model for subjective cognitive impairment, both social isolation and loneliness were significant factors. However, the effect of social isolation became non-significant when loneliness was considered, suggesting a potential mediating role of loneliness. The subsequent mediation analysis confirmed that the indirect effect of social isolation on subjective cognitive impairment through loneliness was significant (B = .20, SE = .03, 95% CI = .12, .28). CONCLUSION: Our analyses provide evidence for the proposed mediating effect of loneliness in the relationship between social isolation and subjective cognitive impairment. Intervention efforts should focus on reducing feelings of loneliness experienced by older immigrants, possibly by engaging them in socially meaningful and cognitively stimulating activities.

Self-rated health as a mediator between physical health conditions and depressive symptoms in older Chinese and Korean Americans.

In the present study, we examined self-rated health as a mediator between physical health conditions (chronic diseases and functional disability) and depressive symptoms in older Chinese and Korean Americans. Using harmonized data (N = 5,063) from the Population Study of Chinese Elderly (PINE) and the Study of Older Korean Americans (SOKA), we tested direct and indirect effect models. In both groups, chronic diseases and functional disability were closely associated with negative ratings of health and symptoms of depression. Analyses with the PROCESS macro showed that the effect of chronic diseases and functional disability on depressive symptoms was mediated by self-rated health in both groups; the indirect effect was greater in the Korean American sample than in the Chinese American sample. These findings contribute to the understanding of the psychological mechanisms that underlie the mind-body connection and highlight the potential importance of subjective health assessment as a useful tool for health promotion.

Preference for patient-provider ethnic concordance in Asian Americans.

Objectives: The present study examined factors associated with the preference for patient-provider ethnic concordance in Asian Americans.Design: With data drawn from the 2015 Asian American Quality of Life Survey (N = 2535), a logistic regression model of the preference for patient-provider ethnic concordance was tested with demographic (age, gender, ethnicity, marital status, education), health and access (chronic medical conditions, self-rated health, health insurance coverage), immigration-related (place of birth, length of stay in the US, English proficiency, acculturation), and adverse experience (perceived discrimination, communication problems in healthcare settings) variables.Results: Over half (52.4%) of those in the sample preferred to be treated by a healthcare provider from their own ethnic background. In a multivariate model, the odds for preferring ethnic concordance were 1.52-1.64 times higher among individuals in earlier stages of immigration, language acquisition, and acculturation. Individuals who had experienced communication problems in healthcare settings presented 3.74 times higher odds for preferring ethnic concordance than did counterparts without such experience.Conclusions: The results emphasized the value of paying attention to patient-provider concordance when treating Asian Americans either relatively new to the country or who have had previous problems communicating with health professionals. The findings also provide implications for improving workforce diversity in healthcare delivery and medical education.

Older Korean Americans' concern about Alzheimer's disease: the role of immigration-related factors and objective and subjective cognitive status.

Objectives: The present study examined the associations between immigration-related factors and objective and subjective cognitive status with older Korean Americans' concern about developing Alzheimer's Disease (AD). It was hypothesized that (1) AD concern would be associated with immigration-related factors and (2) self-rated cognitive status would mediate the relationship between cognitive performance (Mini Mental State Examination (MMSE) scores) and concern about AD.Method: Using data from the Study of Older Korean Americans (n = 2061, mean age = 73.2; 66.8% female), the direct and indirect effect models were tested.Results: Korean American immigrants with a higher level of acculturation had better cognitive performance, more positive self-ratings of cognitive status, and a lower level of concern about AD. Both poor cognitive performance and negative self-ratings of cognitive status were associated with increased concern about AD. Supporting the mediation hypothesis, the indirect effect of cognitive performance on AD concern through self-rated cognitive status was significant (bias corrected 95% confidence interval for the indirect effect = -.012, -.003).Conclusion: The mediation model not only helps us better understand the psychological mechanisms that underlie the link between cognitive status and AD concern but also highlights the potential importance of subjective perceptions about cognitive status as an avenue for interventions.

The role of self-rated mental health in seeking professional mental health services among older Korean immigrants.

OBJECTIVES: The gap between mental health needs and service use in racial/ethnic minorities continues to be a major public health concern. Focusing on older Korean immigrants, the present study examined linkages among mental distress, self-rated mental health (SRMH), and the use of professional mental health services. We hypothesized that SRMH would play a mediating role in the relationship between mental distress and the use of professional mental health services. METHOD: Using data from the Study of Older Korean Americans (SOKA; N = 2,150, Mean age = 73.4), the direct and indirect effect models were tested. RESULTS: Nearly 30% of the sample fell within the category of experiencing mental distress, but only a small proportion (5.7%) had used professional mental health services. Supporting our hypothesis, the pathway from mental distress to the use of professional mental health services was influenced by an individual's subjective perception of mental health status: the indirect effect of mental distress on service use through SRMH (.04 [.01]) was significant (bias-corrected 95% confidence interval for the indirect effect = .02, .06). CONCLUSION: The findings of this study not only contribute to our understanding of help-seeking processes in a group at high mental health risk but also suggest avenues to promote their use of mental health services.

The Role of Social Networks on Depressive Symptoms: A Comparison of Older Koreans in Three Geographic Areas.

The purpose of this study was to examine the correlates of depressive symptoms among older Korean adults in three geographic locations with varying densities of the Korean population: mainland Korea (mostly Koreans), New York metropolitan area (high Korean density), and west central Florida (low Korean density). The study focused on the role of family and friend networks. Data were drawn from three sources: (1) a multistage national sample of Koreans in South Korea (n = 403); (2) a survey conducted in the western/central Florida area that used a variety of culturally sensitive sampling strategies (n = 672); and (3) a survey in the New York metropolitan area (n = 420) that replicated the Florida study. For those living in Korea, living alone and lower perceived financial status were independently associated with higher levels of depressive symptoms. For the New York and Florida samples, fair or poor self-rating of health, lower levels of acculturation, and weaker ties with family were related to higher levels of depressive symptoms. Similar to the older Korean sample, lower perceived financial status was linked with greater depressive symptoms in the New York sample. The overall results suggest that it is important to consider the interplay of the social network, personal, and cultural resources when working with older adults in diverse contexts. Intervention efforts should address mental health issues tailored to cultural and social settings.

Knowledge About Alzheimer's Disease and Awareness of Alzheimer's Disease-Related Services in Older Korean Americans: The Role of Social Capital.

The purpose of the study was to investigate factors associated with Alzheimer's Disease (AD)-related knowledge and service awareness in older Korean Americans. Considering the importance of social resources in the lives of older immigrants, the focus was on exploring the role of social capital-related factors (e.g., prior exposure to AD, social network, activity participation, and community social cohesion) on AD knowledge and service awareness. Data were drawn from the Study of Older Korean Americans (SOKA; N = 2,150; Mage = 73.41, SD = 7.97). Findings highlight the critical roles of prior exposure to AD and social network influencing both AD knowledge and service awareness, with activity participation also being associated with the latter. Results suggest that particular attention should be paid to individuals who are culturally and socially isolated when considering interventions.

Self-rated Physical, Mental, Oral, and Cognitive Health in Older Korean Immigrants: The Role of Health Indicators and Sociocultural Factors.

Guided by the models of health assessment and social determinants of health, we examined predictors of self-rated physical, mental, oral, and cognitive health of older Korean immigrants. Data came from the Study of Older Korean Americans (SOKA; N = 2,061, Mean age = 73.2). Multivariate regression models of self-ratings of health were tested with health indicators (both domain-specific and other health indicators including chronic disease, functional disability, mental distress, problems with teeth or gums, and cognitive function) and sociocultural factors (acculturation, social network, and ethnic community social cohesion). For self-rated physical, mental, and oral health, indicators specific to the targeted domain played a primary role, with those of other health domains playing a secondary role. Acculturation and social network were significant predictors of all four measures. Findings highlight the importance of holistic health assessment that considers a wide range of health domains as well as sociocultural contexts.
