Social support has been widely known as a protective factor for the emotional well-being (EWB) of older adults, but less studies have investigated the roles of different sources of social support (i.e., family and friend support) on different facets of EWB (i.e., positive affect and negative affect) simultaneously. In this study, the associations between family/friend support and positive/negative affect were investigated in a sample of 700 Chinese elderly. The EWB and social support were measured with a 12-item affective wordlist (Kahneman et al., 2004) and a self-prepared questionnaire. The results showed that (1) the order of contact frequency and mutual support followed a hierarchical order from spouse, children, to friends; (2) zero-order correlations of both family support and friend support were associated with more positive affect and less negative affect; and when compared with the relative role of family and friend support, (3) spouse (children if spouse is not available) support had greater contribution on decreasing negative affect, while friend support had greater influence on increasing positive affect, even after controlling the demographic, self-rated health and life events variables. Family and friend support play different roles on the two facets of EWB of the elderly. These results were better explained in light of the task specificity model rather than the hierarchical compensatory model. Moreover, positive affect may be enhanced by friend support (based on personal interests and selectable) rather than family support (bonded by kinship and not selectable), which added evidences to the socioemotional selectivity theory.

Objectives: Embedded in a traditional culture where filial piety was honored, living with adult children once had been the most prevalent living arrangement and the best option for Chinese elderly people. This study examined whether co-residence with adult children would be still beneficial to the psychological well-being (PWB) among the oldest old (aged 80 and above) in China today. Method: Using data from the fifth wave of the Chinese Longitudinal Healthy Longevity Survey conducted in 2008, the authors examined the living arrangements among the total sample (n = 12,213) and the association between living arrangement and PWB among a subsample (n = 7037) of respondents with normal cognition. Results: (1) More than half (67.1%) of the unmarried oldest old reported being co-resided with their children; while for the married oldest old, the majority of the respondents (62.4%) lived with a spouse only. (2) For the widowed, co-residence with adult children was associated with better PWB compared to living alone; but for the married, co-residence did not bring additional benefits to the PWB. (3) Co-residence of the widowed and children was associated with better life satisfaction compared to living with a spouse only, while it was associated with lower emotional well-being compared to living with a spouse (with or without a child). Conclusion: These findings suggest that living arrangements of Chinese oldest old are partially getting westernized, and a majority of them adapt it well. Government programs need to be developed to assist the Chinese oldest old (especially widowed) to live independently.

Objectives: Intergenerational support is associated with fewer depressive symptoms in old age. Uneven development has resulted in huge urban–rural disparities in China, which could lead to different intergenerational relationships. The present study aimed to examine whether intergenerational support was associated with depressive symptoms differently among urban and rural Chinese older participants.Methods: A sample of 3,498 participants from nine pairs of urban subdistricts and rural villages were included in the present study. Depressive symptoms were measured by the 10-item Center for Epidemiological Studies Depression Scale, and the intergenerational support mechanisms (financial, instrumental, and emotional) were assessed with a self-designed questionnaire.Results: Significant areas by support effect for depressive symptoms indicated different associations between intergenerational financial and emotional support and depressive symptoms in urban and rural areas. Specifically, urban older participants receiving emotional support from adult children and rural older participants receiving financial support from adult children showed fewer depressive symptoms. In both areas, participants receiving instrumental support showed fewer depressive symptoms.Conclusion: Our study is the first to compare the urban–rural disparity in association between intergenerational support and depressive symptoms in a developing country, China. The results support modernization theories proposing weakened economic function but intensified emotional ties in societies with higher level of development. Communication-based intergenerational emotional support should be promoted in urban areas, and formal support systems should provide financial and instrumental support to the vulnerable rural older population.

Inhibition deficit plays a crucial part in cognitive aging; however, few studies have systematically investigated the plasticity of various inhibitory processes among older adults. We studied the plasticity of 3 inhibitory processes (access, deletion, and restraint) and the extent of far transfer of inhibition training to other general cognitive abilities. Thirty-six participants (aged 60 years and above, M = 70.06, SD = 5.53) were randomly assigned to an adaptive training group that received 12 sessions of training covering 3 inhibitory processes or an active control group that received 4 sessions of mental health lectures. Participants in both groups completed pre- and posttest assessments, in which behavioral and electrophysiological measures were used to evaluate potential transfer effects. Direct training gains were observed for trained tasks of all inhibitory processes, but near-transfer effects were only found within untrained tasks associated with deletion at a composite score level. Furthermore, far-transfer effects were demonstrated for fluid intelligence (Gf) but not for working memory or other general cognitive abilities. Near transfer to deletion and far transfer to Gf persisted at a 3-month follow-up assessment session. We discussed differences in plasticity between the 3 inhibitory processes as well as their possible associations with far transfer to Gf. (PsycINFO Database Record

Objectives: Older adults become more inactive and frailer with aging. Physical status is closely linked to mental health, but it is unclear which physical indicator is more strongly associated with depressive symptoms in older adults. The present study aimed to compare relationships between self-reported physical activity, physical frailty (muscle mass, muscle strength, and gait ability) and depressive symptoms in community male and female older adults.Methods: A total of 1,180 adults aged 60 years and older were recruited to participate in this study from a Chinese community receiving annual check-up service from September 2018 to May 2019. Physical activity was assessed by the International Physical Activity Questionnaire (IPAQ). The Bio-electrical Impedance Analyzer was used to determine the muscle mass. As the indicators of muscle function, grip strength and gait ability were assessed by the dynamometer and Timed Up and Go Test (TUGT), respectively. The 15-item version of Geriatric Depression Scale (GDS-15) was used to examine depressive symptoms. Demographic variables, health status and sleep quality were collected using questionnaire.Results: 11.8% men and 11.9% women reported depressive symptoms. Logistic regression showed that depressive symptoms was associated with low grip strength (OR = 2.42, 95% CI: 1.04–5.63), slow gait ability (OR = 3.60, 95% CI: 1.28–10.13) in older males, and associated with low level of self-reported physical activity (OR = 3.85, 95% CI: 2.00–7.42) in older females. No significant association was found between muscle mass and depressive symptoms.Conclusion: There were gender differences in the relationship between physical activity, physical frailty, and depressive symptoms. Grip strength and gait ability may be a better indicator of frailty for predicting depressive symptoms in older men while physical activity may be useful in predicting depressive symptoms in older women.

Working memory updating (updating) and working memory capacity (WMC) have been assumed to share a common mechanism. However, it is unclear whether WMC can be expanded by boosting the efficiency of updating, particularly during late adulthood. In this randomized controlled study, 33 older adults (aged 60 years and above, M = 69.53, SD = 5.21) were assigned to updating training (n = 17) and contact control (n = 16) groups. In the training group, updating was targeted by a running memory task and a chess game in each training session; whereas in the control group, motivational effects were estimated by their attendance to a series of mental health-related lectures. The boosted updating efficiency was demonstrated by direct training gains over sessions on updating criterion/training tasks, and significant frontocentral inflation at the N2 time range. Near transfer effects were revealed on untrained similar measures immediately after training and partly maintained at a 3-month follow-up. Far transfer effects to WMC were revealed by a significant increase in contralateral delay activity (CDA) ERP measures, although these effects did not manifest on WMC span tasks and other far transfer measures. Note that increased CDA was significantly correlated with the extent of direct gains in updating training. Our findings suggest that updating efficiency can be boosted in older adults; although it has not yet brought about an explicit expansion of WMC in our behavioral measures (i.e., on span tasks), capacity-related neural changes (i.e., on CDA) have nevertheless, started to show up in our short-term updating training program.
