Dyadic profiles of couples' self-perceptions of aging: Implications for mental health.

The way older adults perceive their own aging processes influences their mental health, but we know little about how this occurs in a dyadic context, where spouses' perceptions and health are often intertwined. The present study sought to identify dyadic profiles of self-perceptions of aging (SPAs) in couples and examine how certain profiles are associated with each partner's mental health over time. A pooled sample of 3,850 heterosexual couples aged 50+ in the Health and Retirement Study (2012/2014) rated positive and negative SPAs and provided data on demographic characteristics, couple relationships, and health. We tracked these couples' depressive symptoms over 2 years (2014/2016). Latent profile analysis revealed five profiles of couples' SPAs: similarly positive (20%), similarly negative (6%), similarly average (38%), husband negative (20%), and wife negative (17%). Physical health and marital quality consistently differentiated couples in profile membership. Couples with similarly positive and similarly average SPAs reported the smallest increases in depressive symptoms over time, and couples with similarly negative SPAs fared worst in mental health. We observed interesting gender differences across profiles; husbands in the husband negative profile reported significantly greater increases in depressive symptoms than those in the wife negative profile. Yet, wives in these two profiles did not differ in their depressive symptoms over time, and they reported worse mental health than wives in the similarly positive and similarly average profiles. This study adds to the emerging literature that advocates for an interpersonal approach to SPAs and reveals risk and resilience in couples as they age together.

Empathy and support exchanges in couples coping with early-stage Alzheimer's disease.

OBJECTIVES: Research has extensively examined spousal caregiving in Alzheimer's disease (AD), but it remains unclear how people with AD help spousal caregivers. We aimed to describe emotional and practical support that people with AD and their spouses provide to each other and test the role their empathy plays in these support experiences. METHODS: Seventy-two people with early-stage AD and their spousal caregivers independently reported empathy (personal distress, empathic concern, perspective taking) and the frequency and appraisal of support provision. Caregivers reported both partners' sociodemographic characteristics. RESULTS: People with early-stage AD and their spousal caregivers provided support to each other often. Caregivers provided more support but people with AD appraised support provision as more pleasant and less stressful. Lower personal distress in both partners and greater caregiver empathic concern were associated with more frequent caregiver support to people with AD. Greater empathic concern and perspective taking were associated with more pleasant appraisals of helping. Personal distress was positively associated with stress of helping. CONCLUSION: Findings describe support reciprocity in early-stage AD and debunk the myth of people with AD being only recipients of care. We identify risk and resilience in couples per empathy and inform the design of dyadic interventions to promote mutually beneficial relationships in AD.

Recent advances in permeable polymersomes: fabrication, responsiveness, and applications.

Polymersomes are vesicular nanostructures enclosed by a bilayer-membrane self-assembled from amphiphilic block copolymers, which exhibit higher stability compared with their biological analogues (e.g. liposomes). Due to their versatility, polymersomes have found various applications in different research fields such as drug delivery, nanomedicine, biological nanoreactors, and artificial cells. However, polymersomes prepared with high molecular weight components typically display low permeability to molecules and ions. It hence remains a major challenge to balance the opposing features of robustness and permeability of polymersomes. In this review, we focus on the design and strategies for fabricating permeable polymersomes, including polymersomes with intrinsic permeability, the formation of nanopores in the membrane bilayers by protein insertion, and the construction of stimuli-responsive polymersomes. Then, we highlight the applications of permeable polymersomes in the fields of biomimetic nanoreactors, artificial cells and organelles, and nanomedicine, to underline the challenges in the development of polymersomes as soft matter with biomedical utilities.

Enduring Bonds: Duration and Contact in Close Relationships in Late Life.

BACKGROUND AND OBJECTIVES: Older adults maintain ties to long-duration social partners, some with whom have regular contact, and some with whom have little contact. We asked whether these ties with little contact still offer a sense of connection and security, and buffer effects of interpersonal stress in daily life. Helping older adults foster these ties may improve their mental health. RESEARCH DESIGN AND METHODS: Participants (n = 313) aged 65+ completed a baseline interview reporting duration and contact frequency of their closest ties. Then, participants completed ecological momentary assessments every 3 hours for 5 to 6 days, reporting their social encounters and mood. RESULTS: We classified ties according to duration (10+ years = long- vs. shorter-duration) and frequency of contact (at least once a month = active vs. dormant). Throughout the day, participants were more likely to have stressful encounters with long-duration active ties. Encounters with active ties were associated with more positive mood (regardless of duration) and encounters with long-duration dormant ties with more negative mood. Having more active ties buffered effects of interpersonal stress on mood but more long-duration dormant ties exacerbated these effects. DISCUSSION AND IMPLICATIONS: Supporting social integration theory, ties with frequent contact were associated with positive mood. Surprisingly, long-duration ties with infrequent contact exacerbated effects of interpersonal stress on mood. Older adults who lack contact with long duration social partners may be more sensitive to interpersonal stress. Future interventions might focus on phone or electronic media to increase contact with long-duration social partners.

Strong and Tough Nanostructured Hydrogels and Organogels Prepared by Polymerization-Induced Self-Assembly.

In nature, the hierarchical structure of biological tissues endows them with outstanding mechanics and elaborated functions. However, it remains a great challenge to construct biomimetic hydrogels with well-defined nanostructures and good mechanical properties. Herein, polymerization-induced self-assembly (PISA) is for the first time exploited as a general strategy for nanostructured hydrogels and organogels with tailored nanodomains and outstanding mechanical properties. As a proof-of-concept, PISA of BAB triblock copolymer is used to fabricate hydrogels with precisely regulated spherical nanodomains. These nanostructured hydrogels are strong, tough, stretchable, and recoverable, with mechanical properties correlating to their nanostructure. The outstanding mechanical properties are ascribed to the unique network architecture, where the entanglements of the hydrophilic chains act as slip links that transmit the tension to the micellar crosslinkers, while the micellar crosslinkers dissipate the energy via reversible deformation and irreversible detachment of the constituting polymers. The general feasibility of the PISA strategy toward nanostructured gels is confirmed by the successful fabrication of nanostructured hydrogels, alcogels, poly(ethylene glycol) gels, and ionogels with various PISA formulations. This work has provided a general platform for the design and fabrication of biomimetic hydrogels and organogels with tailorable nanostructures and mechanics and will inspire the design of functional nanostructured gels.

Changes in Self-Perceptions of Aging Among Black and White Older Adults: The Role of Volunteering.

OBJECTIVES: Given the health consequences of self-perceptions of aging (SPA), understanding how SPA change among Black and White older adults may shed light on racial disparities in late-life health. The current study is the first to assess whether Black older adults exhibit less favorable patterns of change in SPA than White older adults. We also tested whether the salubrious effect of volunteering on SPA would be particularly salient among Black older adults. METHODS: A pooled sample of adults aged 50+ (N = 10,183; Black: n = 1,672, White: n = 8,511) from the Health and Retirement Study rated positive and negative SPA once every 4 years across 3 waves (2008/2010, 2012/2014, and 2016/2018). We assessed participants' reports on volunteering status in each wave. RESULTS: Growth curve models revealed that positive SPA decreased over time whereas negative SPA increased. Black older adults reported more positive and less negative SPA at baseline and flatter time-related changes than their White counterparts. We found that volunteering was significantly associated with more positive and less negative SPA across waves, but this effect was only evident in White older adults. DISCUSSION: Findings revealed vulnerabilities in White older adults as they experience and perceive age-related changes but also identified volunteering as a way to uniquely protect them. More research is needed to refine our understanding of racial disparities in the United States and help tailor interventions intended to maximize benefits to older adults from diverse backgrounds.

Long-term psychological consequences of parental bereavement prior to midlife: volunteering helps.

OBJECTIVES: Losing a child prior to midlife may be a uniquely traumatic event that continues to compromise parents' well-being in later life. This study compared psychological well-being between bereaved and non-bereaved parents, and examined whether volunteering protects bereaved parents. Because most families have more than one child, we further explored whether the number of living children parents had differentiated bereaved parents in their well-being. METHODS: We analyzed a pooled sample of parents aged 50+ (N = 12,023) from the Health and Retirement Study (2010/2012-2012/2014), including parents who lost a child prior to 50 and those who never lost a child. Two-level linear regression models were estimated to test the associations between child loss, volunteering, and psychological well-being, and examine the moderating effect of number of living children. RESULTS: Bereaved parents reported more depressive symptoms and lower life satisfaction than their non-bereaved counterparts, which was more evident among parents with fewer children alive. Among bereaved parents, volunteering, particularly volunteering 100+ hours/year, was associated with better psychological well-being at baseline; yet, volunteering 1-99 hours/year led to a larger increase in life satisfaction over time. The benefits of volunteering held true regardless of the number of living children. CONCLUSION: This study adds to our understanding of the lasting effect of parental bereavement and suggests volunteering as a potential intervention aimed at helping bereaved older parents. Findings identify parents with fewer children as a particularly vulnerable population in the face of child loss and calls for more resources allocated to help them.

The Impact of Marital Quality as Older Couples Adjust to Dementia Onset.

OBJECTIVES: A burgeoning literature links being married to better cognitive health, but less attention has been paid to how couples view their marital relationships. Couples do not always concur in their assessments, and such discrepancies affect both partners' health. We present a dyadic study on whether and how overall and discrepant views of marital quality predicted (a) dementia onset and (b) changes in older adults' depressive symptoms with spousal dementia. METHODS: A pooled sample of couples aged 50+ (dyad N = 3,936) from the Health and Retirement Study rated positive and negative marital quality at baseline (2006/2008). Each participant reported whether they had been told of having dementia and their depressive symptoms once every other year (2006/2008-2014/2016). RESULTS: Cox proportional hazards regression revealed that older adults who rated their marriages either more positively or more negatively than their spouses were more likely to develop dementia. We applied multiphase growth curve modeling to older adults whose spouses developed dementia, finding that those in marriages that were more negative overall reported more depressive symptoms but exhibited a smaller increase in these symptoms in response to spousal dementia. DISCUSSION: This study adds to the literature by showing how discrepant marital assessments shape cognitive aging and offers new insights into identifying older adults with greater dementia risk. Findings also revealed the impact of overall negative marital quality on older adults' psychological adjustment to spousal dementia, which could inform interventions intended to help couples better cope with early-stage dementia from a relational perspective.

Black and White Young Adults' Support to Midlife Parents.

OBJECTIVES: Prior research suggests that midlife adults in Black and non-Hispanic White families differ in support patterns to aging parents. It is unclear whether such racial differences exist in young adulthood. We examined Black and White young adults' support to their midlife parents and underlying mechanisms to explain within-racial group, family-level differences. METHOD: Young adults (aged 18-30; Black n = 107 and White n = 351) from the Family Exchanges Study 2 reported how often they provided tangible (practical) and intangible (emotional support and advice) support to each parent. Participants also reported beliefs about obligation to support parents, rewards from helping, and parental needs. RESULTS: On average, Black young adults provided more tangible and intangible support than White young adults. Feelings of reward predicted why young adults in some Black and White families gave more support than those in other families. Parental needs explained tangible support in Black families and intangible support in White families. Within families, rewards and parental needs drove Black offspring to give more intangible support than their siblings, while obligation motivated White offspring. DISCUSSION: Consistent with support patterns evident in older adulthood, Black young adults gave more tangible and intangible support to their midlife parents compared to White young adults. Within-race support patterns were explained by different factors informed by the Multidimensional Intergenerational Support Model. Findings suggest psychological factors contribute to between- and within-racial patterns of exchanges.

Association Between Music Engagement and Episodic Memory Among Middle-Aged and Older Adults: A National Cross-Sectional Analysis.

OBJECTIVES: To determine whether music engagement influences middle-aged and older adults' performance on episodic memory tasks. METHOD: Secondary data analysis of a sample (N = 4,592) of cognitively healthy adults from the 2016 Health and Retirement Study was used for this study. Multivariable regression models were used to analyze the cross-sectional differences in performance on tasks of episodic memory between participants who listened to music (n = 3,659) or sang or played an instrument (n = 989). RESULTS: On average, participants recalled 10.3 words out of a possible 20. Regression analyses showed that both listening to music and singing or playing an instrument were independently associated with significantly better episodic memory. DISCUSSION: The findings provide the first population-based evidence that music engagement is associated with better episodic memory among middle-aged and older adults. Future studies should examine whether the relationship between music engagement and episodic memory can be replicated in other populations and that the association persists in longitudinal studies.

Older Adult's Marital Status, Conversation Frequency, and Well-Being in Everyday Life.

OBJECTIVES: Marital status contributes to differences in social experiences and well-being in late life. Yet, we know little about the role of conversation in these processes. Drawing on a functionalist perspective and hierarchical compensatory model, this study aimed to understand (a) whether older adults' marital status is associated with conversation frequency throughout the day, (b) whether contacts with nonspousal ties elicit more conversations among unmarried older adults, and (c) whether conversations exert a stronger effect on mood for unmarried older adults than married older adults. METHOD: Adults aged 65+ (N = 272) provided information about their background characteristics and social partners. Across 5-6 days, they completed ecological momentary assessments reporting their social encounters and mood every 3 hr. Concurrently, electronically activated recorders captured 30 s of sound every 7 min. We compared older adults who were married, widowed, and divorced. RESULTS: Multilevel models revealed that married older adults engaged in more conversations than divorced older adults throughout the day. Contact with friends elicited more conversations for divorced older adults than married older adults. Furthermore, conversations enhanced mood throughout the day, but this effect was more salient for widowed than married older adults. DISCUSSION: Findings highlight the role of marital status in older adults' daily conversational experiences and compensatory processes that may occur. Widowed and divorced older adults differed from married older adults in distinct ways. Divorced older adults may compensate for lack of spouse with friends, whereas widowed older adults may benefit emotionally from engaging in conversations.

Volunteering Dynamics and Life Satisfaction: Self-Perceptions of Aging as a Buffer.

OBJECTIVES: Research has extensively documented the concurrent benefits of being a volunteer (vs a nonvolunteer), but little is known about older adults who once served as a volunteer but then stopped at some point in their lives (i.e., former volunteers). The current study tracked changes in older adults' overall life satisfaction and compared these changes among former volunteers, continuous volunteers, and continuous nonvolunteers. We also examined whether self-perceptions of aging may serve as a long-term psychological buffer and protect former volunteers' life satisfaction after they quit volunteering. METHOD: Data were from the Health and Retirement Study (2006-2016). A pooled sample of participants aged 50+ (N = 10,441) indicated volunteer behaviors every other year, and we identified volunteering dynamics based on their volunteering history across 4 waves (8 years). Participants reported on self-perceptions of aging and life satisfaction in the Leave Behind Questionnaire once every 4 years. RESULTS: Continuous volunteers reported greater subsequent life satisfaction than former volunteers and continuous nonvolunteers 4 years later, when we adjusted for their baseline life satisfaction. Yet, the difference between continuous volunteers and former volunteers was absent among participants with more positive self-perceptions of aging. DISCUSSION: This study reveals a potential discontinuity in the benefits of volunteering as older adults transition out of their volunteer activities. Findings, however, also reveal individual differences by self-perceptions of aging, offering suggestive evidence that may refine interventions to prolong the benefits of volunteering.

Television Viewing, Physical Activity, and Loneliness in Late Life.

BACKGROUND AND OBJECTIVES: Television viewing is the most common leisure activity in late life and may ease loneliness but encourage sedentary behavior. These associations may be particularly evident among older adults who live alone and who may lack other forms of companionship throughout the day. RESEARCH DESIGN AND METHODS: Adults aged 65+ (N = 257) participated, of whom 34% lived alone. Participants completed an initial interview followed by a 5- to 6-day data collection involving multimethods: (a) Electronically Activated Recorders (30 s every 7 min) provided audio recordings of television viewing, (b) Actical accelerometers objectively measured physical activity, and (c) ecological momentary assessments every 3 hr assessed social interactions. RESULTS: On average, older adults spent approximately 37% of their waking time (6.4 hr a day) watching television. Multilevel models revealed that television viewing occurred when participants were alone or with a spouse and was associated with a greater proportion of time sedentary, lower activity, and higher ratings of loneliness compared to when not watching television. Older adults who lived alone reported greater loneliness during 3-hr intervals when viewing television, but older adults who lived with others spent a greater proportion of time sedentary when viewing television. DISCUSSION AND IMPLICATIONS: Findings are discussed with regard to different rationales and ways of watching television-as compensation for social isolation or as a passive leisure activity with a social partner. We discuss ideas for research on additional aspects of television viewing and screen time in late life.

Functional Limitations, Social Integration, and Daily Activities in Late Life.

OBJECTIVES: Disability in late life has been associated with increases in receiving care and loss of autonomy. The Disablement Process Model suggests that physical impairments lead to functional limitations that contribute to disabilities in managing household, job, or other demands. Yet, we know surprisingly little about how functional limitations are related to activities throughout the day among community-dwelling adults or the possible moderating role of social integration on these associations. METHODS: Community-dwelling adults (N = 313) aged 65 and older completed a baseline interview assessing their functional limitations, social ties, and background characteristics. Over 5-6 days, they answered questions about daily activities and encounters with social partners every 3 h on handheld Android devices. RESULTS: Multilevel logistic models revealed that functional limitations are associated with an increased likelihood of activities associated with poor health (e.g., TV watching, medical appointments) and reduced likelihood of social activities, or physical activities, chores, or leaving the home. Most moderation analyses were not significant; family and friends did not mitigate associations between functional limitations and daily activities, with the exception of medical appointments. Individuals with functional limitations were more likely to attend medical appointments when with their social partners than when alone. DISCUSSION: This study provided a modest indication that functional limitations in community-dwelling older adults are associated with patterns of activity that may lead to further limitations, disability, or loss of autonomy. Findings warrant longitudinal follow-up to establish subsequent patterns of decline or stability.

Friendships in Old Age: Daily Encounters and Emotional Well-Being.

OBJECTIVES: Having friends in old age is linked to higher levels of happiness and life satisfaction. Yet, we know little about older adults' emotional experiences when they encounter friends throughout the day. This study examined whether older adults reported (a) more pleasantness, (b) fewer conversations about stressful experiences, and (c) better mood when they had contact with friends compared to when they had contact with other social partners or were alone throughout the day. We also examined whether these experiences varied by the friendship closeness. METHOD: Adults aged 65+ (n = 313) from the Daily Experiences and Well-being Study provided background information and listed and described their close social partners. Participants then completed ecological momentary assessment (EMA) surveys every 3 hr for 5 to 6 days where they reported their encounters with social partners, rated the pleasantness and indicated whether they discussed stressful issues during these encounters, and rated positive and negative mood. RESULTS: Multilevel models revealed that encounters with friends were more pleasant and were associated with fewer discussions about stressful experiences compared to encounters with romantic partners or family members throughout the day. Encounters with friends were also associated with better mood, though this link only held for encounters with friends who were not considered close. DISCUSSION: Findings are discussed in terms of functionalist theory, socioemotional selectivity theory, relationship ambivalence, and the benefits of less close ties. This work facilitates the understanding of how daily contact with friends can promote older adults' emotional well-being.

Volunteering, Self-Perceptions of Aging, and Mental Health in Later Life.

BACKGROUND AND OBJECTIVES: Scholars argue that volunteering enhances social, physical, and cognitive activities that are increasingly valued as people age, which in turn improves older adults' well-being via a host of psychosocial and neurobiological mechanisms. This study explicitly tested older adults' self-perceptions of aging as a mechanism underlying the mental health benefits of volunteering. RESEARCH DESIGN AND METHODS: Using 2-wave data from the Health and Retirement Study (2008/2010 for Wave 1 and 2012/2014 for Wave 2), we analyzed reports from a pooled sample of older adults aged 65 or older (N = 9,017). Participants reported on demographic characteristics, volunteer work (did not volunteer, 1-99 h/year, 100+ h/year), self-perceptions of aging, and depressive symptoms. We estimated an autoregressive cross-lagged panel model. RESULTS: Volunteering for 100 h or more per year was associated with older adults' more positive and less negative self-perceptions of aging in the subsequent wave (i.e., 4 years later), which in turn predicted fewer depressive symptoms. DISCUSSION AND IMPLICATIONS: This study suggests the promising role of volunteering in shaping older adults' self-perceptions of aging on a sustained basis and refines our understanding of the benefits volunteering brings. Findings shed light on future interventions aimed at improving older adults' adjustment to age-related changes and lessening ageism in society.

Functional Limitations, Volunteering, and Diurnal Cortisol Patterns in Older Adults.

OBJECTIVES: Older adults often experience functional limitations that affect their everyday lives, but many of them continue to make positive contributions to society and benefit from these contributions themselves. We examine (a) whether older adults' functional limitations are associated with diurnal cortisol patterns and (b) whether these associations vary on volunteering days versus nonvolunteering days. METHODS: Participants were adults aged older than 60 years (N = 435) from the National Study of Daily Experiences, part of the Midlife in the United States Study. They completed an initial interview on functional limitations and background characteristics, indicated volunteering activities in daily interviews, and also provided salivary samples across 4 days. RESULTS: Multilevel models showed that older adults with greater functional limitations exhibited dysregulated cortisol awakening responses and diurnal cortisol slopes throughout the rest of the day, compared to older adults with lower limitations. Yet, we also observed a significant moderating effect of volunteering on these associations. DISCUSSION: This study advances our understanding of functional limitations and cortisol stress responses, revealing the benefits of volunteering to older adults who experience these limitations. Rather than treating these older adults solely as care recipients, interventions should offer them opportunities to help others.

Positive Encounters as a Buffer: Pain and Sleep Disturbances in Older Adults' Everyday Lives.

Objectives: To test whether older adults' pain was bidirectionally associated with nighttime sleep disturbances and whether daily positive encounters attenuated these associations. Methods: Participants (N = 292, mean = 73.71 years old) from the Daily Experiences and Well-being Study indicated pain and positive encounters with close partners (e.g., family and friends) and nonclose partners (e.g., acquaintances and service providers) every 3 hours throughout each day across 4-6 days. They also reported nighttime sleep disturbances the following morning. Results: Multilevel models revealed that participants with more prior nighttime sleep disturbances reported more severe pain the next day. This link was attenuated on days when participants had a greater proportion of positive encounters or viewed encounters as more pleasant, especially when these encounters occurred with close partners. Discussion: This study identifies benefits of positive encounters to older adults and sheds light on ways that may alleviate their pain from a social perspective.

Empathy and Coping: Older Adults' Interpersonal Tensions and Mood throughout the Day.

INTRODUCTION: Scholars have proposed that empathy is a key feature of strong social ties, but less is known about the role empathy plays when tensions arise. OBJECTIVE: We examined whether older adults' empathy was associated with (a) coping strategies for interpersonal tensions, and (b) mood when there were tensions throughout the day. We also explored whether coping strategies explained the potential buffering effect of empathy on older adults' momentary mood. METHODS: Older adults (N = 302) from the Daily Experiences and Well-Being Study completed a baseline survey on empathy and coping strategies. They also completed ecological momentary assessments every 3 hours each day for 5-6 days, which included questions about interpersonal tensions and mood. This study considered tensions with close partners (e.g., family and friends) and with non-close partners (e.g., acquaintances and service providers). RESULTS: In the face of interpersonal tensions, more empathic older adults reported using more constructive and less destructive coping strategies than less empathic older adults, regardless of their closeness to social partners. Being more empathic also buffered older adults' mood when tensions occurred with close partners, but this buffering effect was not mediated by older adults' general preference for coping strategies. CONCLUSION: This study advances our understanding of empathy and interpersonal tensions in later life, with a focus on daily experiences.
