The Mediating Role of Loneliness in the Relation Between Social Engagement and Depressive Symptoms Among Older Korean Americans: Do Men and Women Differ?

OBJECTIVES This study conceptualized loneliness as a mediator in the relation between social engagement and depressive symptoms and explored gender differences in the mediation model. Various indices of social engagement were considered including living arrangement, social network, and activity participation. METHOD Using data from 674 community-dwelling Korean American older adults, we first examined the mediation effect of loneliness in the relation between each of 3 indices of social engagement (not living alone, social network, and activity participation) and depressive symptoms. Subsequently, gender differences in the mediation model were examined. RESULTS As hypothesized, loneliness was found to mediate the relation between each of the indices of social engagement and depressive symptoms in both men and women. We also observed gender differences in the strength of mediating effects; the effect of living alone was more likely to be mediated by loneliness among men, whereas women showed greater levels of mediation in the models with social network and activity participation. DISCUSSION Our findings suggest that loneliness may explain the mechanism by which deficits in social engagement exerts its effect on depressive symptoms and that gender differences should be considered in interventions targeting social engagement for mental health promotion.

An Empirical Typology of Social Networks and Its Association With Physical and Mental Health: A Study With Older Korean Immigrants

OBJECTIVES In the context of social convoy theory, the purposes of the study were (a) to identify an empirical typology of the social networks evident in older Korean immigrants and (b) to examine its association with self-rated health and depressive symptoms. METHOD The sample consisted of 1,092 community-dwelling older Korean immigrants in Florida and New York. Latent class analyses were conducted to identify the optimal social network typology based on 8 indicators of interpersonal relationships and activities. Bivariate and multivariate analyses were conducted to examine how the identified social network typology was associated with self-rating of health and depressive symptoms. RESULTS Results from the latent class analysis identified 6 clusters as being most optimal, and they were named diverse, unmarried/diverse, married/coresidence, family focused, unmarried/restricted, and restricted. Memberships in the clusters of diverse and married/coresidence were significantly associated with more favorable ratings of health and lower levels of depressive symptoms. DISCUSSION Notably, no distinct network solely composed of friends was identified in the present sample of older immigrants; this may reflect the disruptions in social convoys caused by immigration. The findings of this study promote our understanding of the unique patterns of social connectedness in older immigrants.

Early Adolescent Pathways of Antisocial Behaviors in Poor, Inner-City Neighborhoods

The change and stability of antisocial behavior during adolescence has triggered interest in a number of social scientific disciplines. This article longitudinally examines pathways of antisocial behavior among predominantly African American adolescents residing in inner-city, poor neighborhoods. Data were collected from 354 youth (ages 12 through 15) in an ongoing longitudinal study designed to identify the life-course trajectories of behaviors and associated developmental outcomes in inner-city youth. Growth mixture modeling was used to classify antisocial behavior trajectories, which identified three distinct developmental trajectories of antisocial behavior: high starter, incremental, and steady. Understanding developmental trajectories of antisocial behaviors is important in that it informs prevention and intervention efforts, particularly for high-risk youth populations.

Hospice Use Among African Americans, Asians, Hispanics, and Whites: Implications for Practice

Objective: This study examined the characteristics of individuals in hospice care by racial/ethnic groups. Methods: A total of 22,936 patients served by a hospice in Central Florida during a four-year period, from 2002 to 2006, were included. Of these, 80.6% were White, 9.6% were Black/African-American, 9.3% were Hispanic and 0.5% were Asian American/Pacific Islander. We examined the associations between the characteristics of hospice users and race/ethnicity, and change of hospice user characteristics over time using chi-square and ANOVA tests. Results: More females than males were represented. Spouse caregivers were most common for Whites (35%) and Asian/Pacific Islanders (36%). However, “other” (41%) caregivers were most frequent for African Americans and daughters (33%) were most often caregivers for Hispanics. Cancer was the primary diagnosis across the four groups. Racial/ethnic minorities were more likely to rely on Medicaid than Whites (10-70% vs. 4%) and African Americans were most likely to be transferred from hospital (57%), whereas Whites were referred from assisted living/nursing homes more frequently than others(16% vs. 7-10%). Conclusion: As the hospice settings become more racially/ethnically diverse, it is essential to attend to the different circumstances and needs of the various groups in providing optimal care.

9/11: WHAT DID WE KNOW AND WHEN DID WE KNOW IT?

In February 1998, Osama Bin Laden published a signed statement calling for a fatwa against the United States for its having ‘declared war against God’. As we now know, the fatwa resulted in the unprecedented attack of 9/11. The issue of whether or not 9/11 was in any way predictable culminated in the public debate between Richard Clarke, former CIA Director George Tenet and the White House. This paper examines whether there was any evidence of a structural change in the terrorism data at or after February 1998 but prior to June 2001, controlling for the possibility of other breaks in earlier periods. In doing so, we use the standard Bai–Perron procedure and our sequential importance sampling (SIS) Markov Chain Monte Carlo (MCMC) method for identifying an unknown number of breaks at unknown dates. We conclude that sophisticated statistical time‐series analysis would not have predicted 9/11.

The impact of social resources on depressive symptoms in racially and ethnically diverse older adults: variations by groups with differing health risks.

The objectives of this study were (1) to develop an empirical typology of physical health risks in racially and ethnically diverse older adults and (2) to examine whether the impact of social resources on depressive symptoms differs across the identified health risk groups (low, moderate, and high risks). The data source was the Survey of Older Floridians, a statewide survey of older adults aged 65 and older (n = 1,432). Latent profile analysis with multiple indicators of physical health (chronic conditions, functional disability, and self-rated health) was used to identify three health risk groups (low, moderate, and high risks). The direct and interactive effects of the health risk group membership and social resources (social support and religious service attendance) on depressive symptoms were found. Of particular interest was that the positive impact of social support was most pronounced in the moderate health risk group.

The relation between living alone and depressive symptoms in older Korean Americans: do feelings of loneliness mediate?

Objectives: As the opposite end of the continuum from social integration, social isolation may put individuals at a greater risk of poor mental health. Conceptualizing living alone as an objective and structural indicator of social isolation and loneliness as subjective perceptions of social isolation, the present study hypothesized that the relation between living alone and depressive symptoms would be mediated by the feelings of loneliness. Using older Korean Americans as the target population, the mediation model was examined in consideration of the contextual factors such as demographics (age, gender, education, perceived income, and length of stay in the USA), health (chronic conditions and functional disability), and general social integration (size of social network and community social cohesion). Method: Date were drawn from surveys with 209 older Korean Americans in Central Texas (Mage = 69.6, SD = 7.5). Multivariate regression models of depressive symptoms were entered in the following order: (1) demographics, (2) health, (3) living alone, (4) social network/community social cohesion, and (5) loneliness. The mediation effect of loneliness in the relationship between living alone and depressive symptoms was separately examined using the bootstrapping method. Results: Loneliness was found to mediate the relation between living alone and depressive symptoms (indirect effect = 1.03, 95% CI = .05–2.08). Conclusion: The results suggest that subjective perceptions of loneliness may explain the mechanism through which objective social isolation presents risks for depressive symptoms in older Korean Americans.

Correlates of attitudes toward personal aging in older assisted living residents.

This study explored factors contributing to older adults’ self-perceptions about their own aging in assisted living (AL) communities. Data analysis was completed based on interviews with 150 older residents from 17 AL communities. Multiple regression analyses found that functional disability and hearing impairment negatively affected attitudes toward personal aging among AL residents, and satisfaction with social support positively influenced attitudes. Health perception mediated attitudes toward personal aging. Findings suggest the importance of social workers helping older AL residents recognize social support as a means of promoting their positive self-regard.

Racial/Ethnic Differences in Predictors of Self-Rated Health Findings from the Survey of Older Floridians

The present study examined how self-rated health was influenced by sociodemographic characteristics, physical health indicators, and sociocultural resources among four racial/ethnic groups of older adults. The data source was the Survey of Older Floridians, a statewide sample of Whites (n = 503), African Americans (n = 360), Cubans (n = 328), and non-Cuban Hispanics (n = 241) who were age 65 and older. Hierarchical regression models of self-rated health were estimated to explore the direct effects of the predictor variables as well as their interactive roles in each racial/ethnic group. Compared to Whites, racial/ethnic minority older adults rated their health more poorly. Although physical health indicators were significant predictors of self-rated health across all groups, the authors found group-specific predictors and interactions. Findings show similarities and differences in predictors of self-rated health across diverse racial/ethnic groups and suggest the importance of understanding group-specific factors in efforts to improve older adults’ perceived and actual health.

Willingness to Use Mental Health Services Among Older Residents in Assisted Living

Examining the importance of mental health care in assisted living (AL) settings, the present study examines older AL residents’ willingness to use mental health services and its predictors. Data based on face-to-face interviews with 150 older residents from 17 AL settings in Florida are used in the analyses (Mage = 82.8, SD = 9.4). Multivariate logistic regression is used to estimate the likelihood of willingness to use mental health services in relation to predisposing (demographics and physical health), mental health needs (depressive symptoms), and enabling variables (social network, instrumental support, emotional support, informational support, satisfaction with support, and previous use of mental health services). Willingness to use mental health services is predicted by younger age, unmarried status, lower levels of emotional support, and higher levels of informational support. The relationship of informational support to higher willingness to use mental health services suggests that AL residents could benefit from educational interventions on late life depression.
