Dementia Caregiving Experiences Among Korean Americans: Qualitative Inquiry Using the Stress Process Perspective.

Dementia caregiving involves a challenging and complex process, especially for immigrant families. Using a qualitative method, this study provides an in-depth exploration of caregiving experiences among Korean American caregivers of people living with dementia. Based on various sampling strategies, 16 Korean American caregivers of family members/relatives with dementia were recruited in the greater Los Angeles area. Guided by the stress process model and the constant comparative method, themes and subthemes were derived and categorized into four domains: (1) background/context; (2) perception/appraisal; (3) resources/coping, and (4) caregiver burden/reward. Findings suggest that intervention efforts should focus on educating and training dementia caregivers.

Mental Health Impact of Bullying by Ethnic Peers in Senior Housing: A Study with Older Korean American Residents in the Greater Los Angeles Area.

Using data from Korean-American residents (N = 343) in subsidized senior housing in the Los Angeles area, we examined the effect of peer bullying on mental health. About 18% of the sample had been a target of bullying, and over 31% had witnessed someone being bullied. Being a target of bullying was a significant predictor for both depressive symptoms and anxiety, whereas witnessing other residents being bullied was a significant predictor for anxiety only. Findings shed light on the adverse mental health impacts of peer bullying among ethnic minority older residents in senior housing.

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.

The moderating role of social factors in the relationship between an incident of fall and depressive symptoms: a study with a national sample of older adults in South Korea.

OBJECTIVES: The purpose of the study was to examine the effect of an incident of fall on depressive symptoms and the moderating role of social factors (marital status, living arrangement, family network, and friend network) in older adults in South Korea. We hypothesized that the adverse mental health effect of a fall would be pronounced among those who lack social resources (e.g., no spouse, living alone, and social disconnectedness). METHOD: Using the 2017 National Survey of Older Koreans, data were drawn from 8,522 survey participants (aged 65 or older). Multivariate linear regression models of depressive symptoms were examined with an array of predictors: (1) demographic and health variables, (2) social factors, (3) an incident of fall, and (4) interactions between falls and social factors. RESULTS: More than 15% of the sample had at least one fall in the past 12 months. Higher levels of depressive symptoms were associated with an incident of fall, not married and living alone, and lack of family and friend networks. Not married and living alone and family network significantly moderated the relationship between falls and depressive symptoms. The adverse mental health effect of a fall was more pronounced among those who were not married and living alone and who reported not having any close family members than their counterparts. CONCLUSION: The findings highlight the critical role of family and social resources in protecting older Koreans from the negative mental health consequences of a fall. Findings also provide implications for developing fall prevention and management programs, suggesting prioritizing older adults with limited social resources.

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.

Stigmatizing Beliefs About Depression in Diverse Ethnic Groups of Asian Americans.

Focusing on diverse ethnic groups of Asian Americans, the present study examined the prevalence, ethnic variations, and predictors of stigmatizing beliefs about depression (beliefs that associate depression with a sign of weakness, shame to the whole family, and family disappointment, and beliefs that antidepressant medicines are addictive). Data were drawn from 2609 participants (age range 18-98) in the 2015 Asian American Quality of Life survey that includes Chinese, Asian Indian, Korean, Vietnamese, Filipinos, and other Asians. Results of a series of logistic models indicated that age, gender, ethnicity, length of stay in the U.S., English proficiency, and acculturation were significantly associated with stigmatizing beliefs about depression. Ethnic variations in beliefs were also observed. Implications for research and practice are discussed.

Factors Associated With Designation of a Substitute Decision-Maker in Older Asian Americans: The Role of Cultural Factors.

The present study examined the prevalence of and factors associated with the designation of a substitute decision-maker (SDM) in a sample of older Asian Americans. Particular emphasis was placed on cultural factors (ethnicity, time in the United States, English proficiency, acculturation, and cultural belief) that might influence on one's attitudes toward death and dying or end-of-life decision-making. Data were drawn from the 499 participants aged 60 years and older using the 2015 Asian American Quality of Life survey. Twenty-two percent of the sample had completed a legal document identifying a SDM. Results of a hierarchical logistic regression indicated that ethnicity, time in the United States, English proficiency, and acculturation were significant predictors. By examining the role of cultural factors in predicting SDM designation, the present study provided implications for culturally tailored strategies to help older Asian Americans plan their end-of-life care.

Mental Health Service Use and Perceived Unmet Needs for Mental Health Care in Asian Americans.

Using data from the Asian American Quality of Life (AAQoL, n = 2609) survey, logistic regression models of mental health service use and perceived unmet needs were estimated with background variables, ethnicity, and mental health status. More than 44% of the participants were categorized as having mental distress (Kessler 6 [K6] ≥ 6) and 6.1% as having serious mental illness (SMI, K6 ≥ 13). About 23% had used services (mental health specialist, general doctor, and/or religious leader) for their emotional concerns during the past year, and about 7% reported that there was a time that they needed mental health care but could not get it. In the multivariate analyses, the presence of mental distress and SMI increased the odds of using any service and having perceived unmet needs. Those who had used services exhibited higher odds of reporting unmet needs, calling concerns about the quality of services and user satisfaction.

Mechanisms of the Effect of Involuntary Retirement on Older Adults' Self-Rated Health and Mental Health.

This study examined mechanisms of the effect of involuntary retirement on self-rated health and mental health among adults aged 50 or older. Using two waves of the Health and Retirement Study (2006 and 2010), we selected a sample of 1,195 individuals working for pay at baseline who responded to a lifestyle questionnaire in both waves. Regression-based path analyses were conducted to test the mediating effects of financial control, positive and negative family relationships, and social integration on the relationship between involuntary retirement and self-rated health and mental health. Results of mediation analyses indicated that transition to involuntary retirement was directly negatively associated with subsequent self-rated health and indirectly negatively associated with mental health via perception of less financial control. Voluntary retirement was indirectly positively associated with both self-rated and mental health via perception of more financial control. No significant direct or indirect effects of retirement were found when retirement was measured with an aggregate measure without specifying its voluntariness. Findings emphasize the importance of specifying the voluntariness of retirement and recognizing the heterogeneity in the mechanisms of involuntary and voluntary retirement.

The effects of job demands and resources on turnover intention: The mediating roles of emotional exhaustion and depersonalization.

BACKGROUND: Although job demands, supervisory support, and burnout have been identified as significant predictors of turnover intention, little attention has been paid to the mechanisms among these determinants. OBJECTIVE: Based on the job demand and resource (JD-R) model, this study examined the mediating roles of emotional exhaustion and depersonalization. METHODS: Data were collected from private sector social workers in three metropolitan areas of South Korea (N = 316). Two serial multiple mediation analyses were conducted to examine the mediating effects of emotional exhaustion and depersonalization in the relationships between job demands and turnover intention and between job resources and turnover intention, respectively. RESULTS: Job demands and resources were associated with turnover intention both directly and indirectly, through emotional exhaustion and depersonalization. Whereas job demands were positively associated with emotional exhaustion only, job resources were negatively associated with both emotional exhaustion and depersonalization. The sequential link from emotional exhaustion to depersonalization was present in both job demands and in the resources models. CONCLUSIONS: The findings underscore the importance of addressing potential burnout to effectively reduce turnover intention among social workers in South Korea. Implications and strategies for developing interventions and policies to reduce turnover by improving work environments are suggested.

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.

Healthcare Navigation Self-Sufficiency in Older Korean Immigrants.

Using data from surveys with Korean Americans aged 60 years or above (n = 2,150), the level of healthcare navigation self-sufficiency was assessed, and its related factors were explored. The overall status of self-sufficiency was low; for example, over half of the sample needed assistance with reading and filling out medical documents, and nearly half needed someone to interpret during medical visits. Diminished self-sufficiency in healthcare navigation was associated with disadvantaged social status (e.g., advanced age, female gender, and low education), early stages of immigration (short length of stay in the U.S. and low English proficiency), and lack of personal health resources (e.g., poor health condition and lack of health insurance). The findings shed light on older immigrants' challenges in the use of health services in a broad sense and help identify areas of patient burden and avenues for interventions.

Determinants of Self-rated Cognitive Health among Older Korean Americans.

BACKGROUND AND OBJECTIVES: In response to the dearth of information on cognitive health in older ethnic minorities, in the present study, we examined factors associated with self-rated cognitive health (SRCH) in older Korean Americans. Drawing from the World Health Organization's framework of social determinants of health, we examined how a broad spectrum of factors might influence the way in which older Korean Americans perceive and evaluate their own cognitive health. RESEARCH DESIGN AND METHODS: Using data from the Study of Older Korean Americans (SOKA; N = 2,061, mean age = 73.2), a series of hierarchical linear regression models of SRCH was tested with sequential entry of predictors: (1) Mini-Mental State Examination (MMSE) score of cognitive status, (2) demographic variables, (3) physical and mental health status, (4) health behaviors, and (5) socio-cultural and community factors. RESULTS: In addition to cognitive screening outcomes, each set of variables made a significant contribution to the predictive model of SRCH. Positive ratings of cognitive health were observed among older individuals with greater education, good physical and mental health, involvement in regular exercise, and socio-cultural resources (social networks, acculturation, and family solidarity). DISCUSSION AND IMPLICATIONS: The SRCH of older adults goes beyond cognitive screening outcomes, suggesting a need to incorporate the various sources of social determinants when seeking to promote the cognitive health of older populations.

Willingness to Use a Nursing Home in Asian Americans.

This study explores factors associated with willingness to use a nursing home in Asian Americans. Focus is given to demographic variables (age, gender, ethnicity, marital status, and education), health-related variables (chronic medical condition and self-rated health), immigration-related variables (time in the U.S. and acculturation), and family-related variables (family network and family solidarity). Cross-sectional study. Data were drawn from 2551 participants in the 2015 Asian American Quality of Life Survey (aged 18-98). Participants were asked to indicate whether they would be willing to use a nursing home in the future. An affirmative response indicated a personal willingness to use a nursing home. Approximately 38% of the sample demonstrated willingness to use a nursing home. Higher odds for willingness were observed among those with advanced age, female gender, Korean ethnicity (compared with Chinese), better education, presence of a chronic medical condition, longer years of residence in the U.S., and lower levels of family solidarity. Reflecting the current trend of an increase in racial/ethnic minorities in nursing homes, a substantial proportion of the present sample of Asian Americans demonstrated willingness to use a nursing home. Findings on the factors associated with willingness provide implications for policies and services to respond to the long-term care needs of this emerging population.

Factors associated with dental service use of older Korean Americans.

OBJECTIVES: Based on Andersen's healthcare utilization model, the present study examined factors associated with dental service use in older Korean Americans. Focus was on predisposing characteristics (age, gender, marital status, education and region), oral health needs (problems with teeth or gums and self-rated oral health) and enabling factors (dental health insurance, length of stay in the United States, acculturation and family network). METHODS: Using data from surveys with Korean Americans aged 60 or older (N = 2128), a Poisson regression model examined predictors of dental visit in the past 12 months. FINDINGS: More than 21% of the sample reported having a problem with teeth or gums, and over half rated their oral health as either fair or poor. Approximately 71% lacked dental health insurance. The number of dental visits in the past 12 months averaged 1.40 (SD = 1.74), with about 38% having no dental visits at all. Multivariate analyses showed that higher levels of education, the presence of a problem with teeth or gums, dental health insurance coverage, longer length of stay in the United States, and larger family networks were associated with 1.01-1.35 times higher number of dental visits. CONCLUSION: The findings not only confirmed the critical role of dental health insurance as a service enabler but also highlighted the importance of considering older ethnic immigrants' oral health and dental care from the perspectives of culture and family.

Asian Americans' concerns and plans about Alzheimer's disease: The role of exposure, literacy and cultural beliefs.

Responding to the increase of the Asian American population and the growing imperative to address issues on Alzheimer's disease (AD) in diverse populations, this study examined Asian Americans' concerns about AD (both concerns about one's own development of AD and about becoming an AD caregiver) and plans for AD. Focus was given on exploring the role of AD exposure, AD literacy and cultural beliefs about AD in predicting AD-related concerns and plans. Using data from 2,609 participants in the 2015 Asian American Quality of Life survey (aged 18-98), logistic regression models of three outcome measures (concerns about one's own development of AD, concerns about becoming an AD caregiver and plans about AD) were estimated. AD exposure and literacy (perceived knowledge and awareness of services) were common predictors of all three outcomes. Beliefs that associate AD with a normal part of ageing and a matter of fate increased the odds of having AD concerns. The odds of having AD plans were found to be higher among those with such concerns. Findings not only identified the factors associated with the concerns and plans about AD but also informed ways to develop targeted AD interventions for Asian Americans.

The risk typology of healthcare access and its association with unmet healthcare needs in Asian Americans.

Using data from the 2015 Asian American Quality of Life Survey (N = 2,609), latent profile analysis was conducted on general (health insurance, usual place for care and income) and immigrant-specific (nativity, length of stay in the U.S., English proficiency and acculturation) risk factors of healthcare access. Latent profile analysis identified a three-cluster model (low-risk, moderate-risk and high-risk groups). Compared with the low-risk group, the odds of having an unmet healthcare need was 1.52 times greater in the moderate-risk group and 2.24 times greater in the high-risk group. Challenging the myth of model minority, the present sample of Asian Americans demonstrates its vulnerability in access to healthcare. Findings also show the heterogeneity in healthcare access risk profiles.

Measurement Equivalence of English Versus Native Language Versions of the Kessler 6 (K6) Scale: An Examination in Three Asian American Groups.

The use of languages other than English in population-based surveys is necessitated by the linguistic diversities in the United States. However, inclusion of multiple languages in survey data collection raises concerns about whether an instrument administered in different languages functions equivalently across groups. Using the Kessler Psychological Distress Scale 6 (K6), the present study examined differential item functioning (DIF) between surveys conducted either in English or the native language of the groups of Chinese Americans (n = 622), Korean Americans (n = 471), and Vietnamese Americans (n = 513). DIF analyses using a series of multiple indicator multiple cause (MIMIC) models showed that there were substantial differences between English and non-English versions in the endorsement of the K6 items, with patterns that differed by ethnicity. The K4 (depressed) showed DIF in all three groups: non-English survey users consistently showed a higher degree of endorsement compared to their English using counterparts. It is speculated that its translated expression in Asian languages may carry less associations with illness/disorder than the English word, thereby making it easy to endorse among Asian language survey users. Findings suggest a lack of measurement equivalence between the K6 administered in English and Asian languages and call for caution in cross-linguistic contexts.

Job stress and mental health among nonregular workers in Korea: What dimensions of job stress are associated with mental health?

Although nonregular workers experience higher job stress, poorer mental health, and different job stress dimensions relative to regular workers, little is known about which job stress dimensions are associated with poor mental health among nonregular workers. This study investigated the association between job stress dimensions and mental health among Korean nonregular workers. Data were collected from 333 nonregular workers in Seoul and Gyeonggi Province, and logistic regression analysis was conducted. Results of the study indicated that high job insecurity and lack of rewards had stronger associations with poor mental health than other dimensions of job stress when controlling for sociodemographic and psychosocial variables. It is important for the government and organizations to improve job security and reward systems to reduce job stress among nonregular workers and ultimately alleviate their mental health issues.
