The Effects of Charitable Giving on Life Satisfaction of Older Korean Adults: The Moderating Role of Relationship Satisfaction and Social Trust.

OBJECTIVES: This study investigates the effects of charitable giving on the life satisfaction of older Korean adults, examining the moderating role of relationship satisfaction and social trust, as the indicators for social capital. METHODS: Nationally representative sample of individuals aged 65 to100 (N = 8,359) from the 2019 Social Survey was used for the analyses. RESULTS: The results from Coarsened Exact Matching and Structural Equation Modeling show that charitable giving positively affects older Korean adults' life satisfaction. Moreover, the results of moderation analyses suggest that the effects of charitable giving on life satisfaction are stronger for those with lower levels of relationship satisfaction and social trust. DISCUSSION: The results imply that social capital, such as relationship satisfaction or social trust, needs to be taken into consideration when exploring the effects of charitable giving in later life.

Patterns of multimorbidity trajectories and their correlates among Korean older adults.

OBJECTIVE: This study aims to identify distinct patterns of 10-year multimorbidity trajectory among Korean older adults and examine factors associated with the patterns. METHODS: Data were drawn from the six waves of the Korean Longitudinal Study of Ageing (KLoSA, 2006-2016). We examined trajectories of multimorbidity of 1,705 older adults aged 65 and older using Growth Mixture Modeling. Then, the identified patterns were used as dependent variables to examine the correlates of multimorbidity trajectories. Explanatory variables considered were sociodemographic, psychological, health behavioural and interpersonal factors at baseline. RESULTS: Four distinct patterns of multimorbidity trajectories were identified: 'maintaining-low' (59.4%), 'chronically-high' (7.5%), 'moderately-increasing' (26.0%) and 'rapidly- increasing' (7.1%). Gender, depressive symptoms, life satisfaction and frequency of contacts with others were associated with trajectory membership. Specifically, women were more likely to be in the 'chronically-high' group than any other groups. Compared to the 'maintaining-low' group, those with higher levels of depressive symptoms and lower levels of life satisfaction were more likely to belong to the 'chronically-high' group and 'moderately-increasing' group, respectively. Respondents who had less frequent meetings with others in close relationships were more likely to be in the 'rapidly-increasing' group than the 'maintaining-low' group. DISCUSSION: These findings are suggestive of distinct trajectories of multimorbidity across older adulthood, indicating that multimorbidity experiences might differ among older adults. Moreover, results suggest that there may be gender inequalities in multimorbidity trajectories, and that levels of psychological well-being and social engagement could be useful in identifying older adults who are at higher risk of worsening multimorbidity.

Supplementary grandchild care, social integration, and depressive symptoms: longitudinal findings from Korea.

OBJECTIVES: Despite growing concerns about the heavy reliance on supplementary grandchild care in Korea, understanding of its longitudinal effects on the grandparents' mental health has been limited. This study examined whether transition patterns of grandchild care among Korean grandparents were associated with changes in the grandparents' depressive symptoms, directly or indirectly, through changes in two domains of social integration (intergenerational contact and social activities) after controlling for socioeconomic characteristics and baseline levels of depressive symptoms and social integration. METHOD: Using the Korean Longitudinal Study of Aging (N = 4,362), a nationally representative multiwave survey, we examined four possible statuses of grandchild care over a three-year period: started (n = 64), continuous (n = 73), and discontinued (n = 103) caregiving, and non-caregiving (n = 4,121). The proposed mediation model was analyzed using structural equation modeling with non-caregivers as a reference group, and Wald tests were conducted to further examine differences in the effects across the three caregiving groups. RESULTS: The direct effects of grandchild care on depressive symptoms in Korean grandparents were not significant. Rather, those who started or continuously provided caregiving had significantly reduced depressive symptoms via increased intergenerational contact compared to the non-caregiving group. CONCLUSION: These findings indicated beneficial effects of grandchild care on depressive symptoms in Korean grandparents through increased social integration within the family. Implications of the study findings were discussed.

Daily stressors facilitate giving and receiving of emotional support in adulthood.

The aims of the present study were to examine whether daily stressors are associated with engagement in emotional support and whether these associations differ by gender. Analyses were conducted using Wave 2 of Midlife in the United States data and its subproject National Study of Daily Experiences. The sample consisted of adults aged 33 to 84 (N = 1,622). Using multinomial multilevel analysis, we looked at the associations between lagged and concurrent daily stressors with engagement in emotional support. For concurrent associations, people who experienced stressors were more likely to both give and receive, solely give, and solely receive emotional support compared with those who did not have any stressors. Women were more likely to engage in both giving and receiving of emotional support compared with men when they experienced stressors during the same day. In terms of the lagged associations, both men and women who experienced stressors during the previous day were more likely to both give and receive emotional support the next day compared with those who did not experience any stressors during the previous day. These results suggest that experiencing daily stressors facilitates giving and receiving of emotional support at daily level in adulthood.

Predicting Behavior Problems in Korean Preschoolers: Interactions of the SLC6A4 Gene and Maternal Negative Affectivity.

OBJECTIVE: This study aimed to investigate whether maternal negative affectivity (MNA) moderates the effect of genetic polymorphism of SLC6A4 on behavior problems in children. METHODS: Study participants comprised 143 preschoolers and their mothers from South Korea. The Childhood Behavior Checklist and Emotionality, Activity, and Sociability adult scale were used to measure child behavior and maternal affectivity. DNA from saliva was genotyped to determine serotonin transporter polymorphism. RESULTS: MNA appeared to exert effects in externalizing (b =5.78, p＜0.001) and internalizing problems (b =6.09, p＜ 0.001). Interaction between SLCA4 polymorphism and MNA showed effects on externalizing (b =-7.62, p＜0.01) and internalizing problems (b =-9.77, p＜0.01). Children with two short alleles showed considerable differences in both externalizing and internalizing problems according to MNA; however, children with one short allele or none showed relatively few differences in behavior problems due to maternal affectivity. CONCLUSION: The effect of SLC6A4 polymorphism on child behavior seemed to be moderated by MNA. In addition, the impact of MNA was found to vary based on a child’s genetic risk. High MNA may trigger the risk allele while low MNA causes the risk allele to illicit less behavior problems. Children with two short variants of the SLC6A4 gene may benefit from intervention that modulates MNA.

Relationship Between Ties With Adult Children and Life Satisfaction Among the Middle-Aged, the Young-Old, and the Oldest-Old Korean Adults.

One of the important determinants of well-being among aging parents is their relationship with adult children. Using the two waves of the Korean Longitudinal Study of Ageing, this study examined how different types of ties with adult children affect the life satisfaction of the Korean middle-aged, the young-old, and the oldest-old adults. Multigroup analysis was used to see if the effects of ties with adult children differ by the three age-groups. The results showed that frequency of contact had positive effect on life satisfaction for all of the age-groups. However, coresidence with children had a negative effect for the middle-aged, but a positive effect for the oldest-old. Finally, exchanges of support with adult children had significant effects only for the young-old. These results show that the importance of different types of ties with children change according to aging parents' life stages.

What Accounts for the Relationship Between Internet Use and Suicidal Ideation of Korean Older Adults? A Mediation Analysis.

OBJECTIVES: This study sought to examine the relationship between Internet use and suicidal ideation in Korean older adults and the mediating roles of social relationships and depressive symptoms. METHOD: A nationally representative sample of older adults aged 50 or older (N = 6,306), from four waves of the Korean Welfare Panel Study, was used in the analyses. All analyses were conducted using generalized estimation equations, and the mediation effects of social relationship satisfaction and depression in the relationship between Internet use and suicidal ideation were calculated using the product-of-coefficients approach. RESULTS: Internet use was linked with lower levels of suicidal ideation directly and indirectly via the protective effects of Internet use on lowering depression, which was partially mediated by the positive influence Internet use has on older adults' social relationship satisfaction. DISCUSSION: The results support previous theories about the relationship between social relationships, depression, and suicidal behavior and prior results about how the Internet might confer mental and social health benefits to older adults. This suggests that the Internet is an important social and health activity that contributes to lowering suicidal ideation in older adults.

Educational differences in the cognitive functioning of grandmothers caring for grandchildren in South Korea.

This study examined the effects of grandchild care on the cognitive functioning of Korean grandmothers and the moderating role of education. Data were drawn from the Korean Longitudinal Study of Ageing (KLoSA), a nationally representative sample of middle-aged and older adults (N = 2,341). Contrary to much of the current literature, grandchild care was found to be potentially beneficial for grandmothers. For the entire sample, child care had instantaneous effects on grandmothers' cognition, although there were no longitudinal effects. However, when the sample was divided into grandmothers with higher and lower education, child care was both instantaneously and longitudinally beneficial to cognition for grandmothers with higher education. For less educated grandmothers, child care did not have either immediate or lagged effects on cognition. The results partially support the "Use It or Lose It" hypothesis and the "Scaffolding Theory of Cognitive Aging," suggesting that engagement in social activities is beneficial to cognitive health in later life. Results are congruent with previous studies noting that the effects of grandchild care on grandparents are contingent on various conditions and factors such as the educational level of grandparents.
