RESUMO
OBJECTIVES: We examined the extent to which positive affect expression in play interactions between adult children and their parents living with cognitive impairment was associated with lower depressive symptoms and mental health difficulties for both dyad members. Gender differences in positive affect expression were also examined. METHOD: Dyads (N = 126) self-reported their depressive symptoms and mental health difficulties. Dyad members later engaged in a video-recorded play interaction together, and their positive affect expression was observationally coded by trained coders in terms of 'enjoyment', 'laughter', and 'positive affect towards partner'. RESULTS: Findings from mixed models using the Actor Partner Interdependence Model showed that one's partner's positive affect was associated with one's own lower depressive symptoms. There were no significant actor effects or effects of role (parent vs. child). Results also revealed that women expressed more positive affect and had greater mental health difficulties, but not depressive symptoms. We found that one's partner's positive affect expressions were more associated with women's mental health than men's mental health. CONCLUSION: Positive affect expression may be a useful indicator of psychological health in parent-child relationships in which the parent has cognitive impairment. Positive affect may be useful to target in supportive, dyadic, psychosocial interventions.
RESUMO
It is important to examine normative age-related change in substance use risk factors across the lifespan, with research focusing on middle adulthood particularly needed. The current study examined time-varying associations between depressive symptoms and alcohol, cigarette, and marijuana use from modal ages 35 to 55 in a national sample of US adults, overall and by sex. Data were obtained from 11,147 individuals in the longitudinal Monitoring the Future study. Participants were in 12th grade (modal age 18) in 1976-1982 and (for the data reported in this study) were surveyed again at modal ages 35 (in 1993-1999), 40, 45, 50, and 55 (in 2013-2019). Weighted time-varying effect modeling was used to examine age-related change in associations among depressive symptoms, any and heavy use of cigarettes, alcohol, and marijuana. Across midlife, greater depressive symptoms were associated with decreased odds of any alcohol use during the 40 s and 50 s, but with increased odds of binge drinking from ages 35-40, and-at most ages-any and pack + cigarette use and any and frequent marijuana use. The association between depressive symptoms and substance use was generally similar for men and women. Results highlight the increased risk for binge drinking, smoking, and marijuana with higher levels of depressive symptoms and underscore the importance of screening and interventions for depressive symptoms and substance use in midlife.

This study examined links between aspects of parenting behavior and children's cortisol and whether those links varied by child behavioral problems and ethnicity. Participants included children ages 9-15 (N = 159, 75% Latinx) and their primary caregivers from the Los Angeles Family and Neighborhood Survey (L.A.FANS; Wave 2). Children provided saliva upon waking, 30 min after waking, and at bedtime which was analyzed for cortisol. Analyses revealed associations between parenting behavior and cortisol were greater among children who had behavioral problems and these associations were stronger among non-Latinx White children compared to Latinx children. This study moves beyond the current literature by investigating these important associations in a predominately Latinx urban sample of children.

OBJECTIVES: Older adults providing unpaid care to a relative or friend during the COVID-19 pandemic may have diminished self-efficacy in managing their own chronic illness, especially in the context of more complex self-management. We evaluated whether adults aged 50 and older with caregiving roles are more likely to report reduced illness self-efficacy since the pandemic, and whether this link is exacerbated by a higher number of conditions. METHODS: Participants (105 caregivers and 590 noncaregivers) residing in Michigan (82.6%) and 33 other U.S. states completed one online survey between May 14 and July 9, 2020. RESULTS: Controlling for sociodemographic and health characteristics, stressors related to COVID-19, and behavioral and psychosocial changes since the pandemic, caregivers were more likely than noncaregivers to report reduced illness self-efficacy when they had a higher number of chronic conditions. CONCLUSION: These findings highlight the importance of maintaining caregivers' self-care during the COVID-19 pandemic and in future public health crises.

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.

BACKGROUND: Multiple chronic conditions may erode physical functioning, particularly in the context of complex self-management demands and depressive symptoms. Yet, little is known about how discordant conditions (i.e., those with management requirements that are not directly related and increase care complexity) among couples are linked to functional disability. PURPOSE: We evaluated own and partner individual-level discordant conditions (i.e., discordant conditions within individuals) and couple-level discordant conditions (i.e., discordant conditions between spouses), and their links to levels of and change in functional disability. METHODS: The U.S. sample included 3,991 couples drawn from nine waves (1998-2014) of the Health and Retirement Study. Dyadic growth curve models determined how individual-level and couple-level discordant conditions were linked to functional disability over time, and whether depressive symptoms moderated these links. Models controlled for age, minority status, education, each partner's baseline depressive symptoms, and each partner's number of chronic conditions across waves. RESULTS: Wives and husbands had higher initial disability when they had their own discordant conditions and when there were couple-level discordant conditions. Husbands also reported higher initial disability when wives had discordant conditions. Wives had a slower rate of increase in disability when there were couple-level discordant conditions. Depressive symptoms moderated links between disability and discordant conditions at the individual and couple levels. CONCLUSIONS: Discordant chronic conditions within couples have enduring links to disability that partly vary by gender and depressive symptoms. These findings generate valuable information for interventions to maintain the well-being of couples managing complex health challenges.

Middle-aged children may cope in different ways with interpersonal tensions with their aging parents. This study examined coping strategies as a function of parent's age and disability and children's emotions (i.e., guilty feelings and worry). Middle-aged children (N = 378) reported coping strategies when encountering interpersonal tensions with each of parents (N = 482): engagement, acceptance, avoidance, and confrontation. Middle-aged children also indicated how guilty and worried they felt about each parent. Multilevel models indicated that middle-aged children were most likely to use engagement and acceptance strategies, followed by avoidance, and least likely to use confrontation. Results also revealed that middle-aged offspring were more likely to use engagement toward their parents who were older and acceptance toward parents with more disabilities. Furthermore, when middle-aged children had stronger feelings of guilt toward parents, they were more likely to be avoidant and less likely to engage with parents. Worries about parents were positively associated with the use of engagement strategies.

Women are more involved in family ties than men, but these differences may vary across generations as gender roles have shifted. We know little about gender patterns across generations in the same family, however. To address this gap, midlife men and women aged 40-60 (n = 633) from the Family Exchanges Study reported on relationships with each aging parent and each grown child. Mothers were more involved (e.g., more frequent contact, greater positive and negative relationship qualities, and more frequent support exchanges) than fathers in both generations, with parental gender differences stronger in the older generation. Offspring gender differences were generally consistent across generations, with daughters more involved by phone in emotional forms of support, and in negative relationship quality; these gender differences were stronger in the younger generation than the older ones. We discuss pervasive gender differences that favor mothers, as well as shifts in gender differences across generations.
RESUMO
Background: Loneliness has been linked to greater substance use, especially among women. Yet little is known about how loneliness is associated with treatment outcomes for patients with opioid use disorder (OUD). Objectives: We evaluated how patient reports of using illicit opioids (i.e. heroin or non-prescription pain medications) are linked to perceptions of loneliness in a sample of adults receiving methadone maintenance treatment (MMT), and whether this link varies by gender. Methods: Participants for this cross-sectional observational study included 371 MMT patients aged 18 and older drawn from four opioid treatment programs in Southern New England and the Pacific Northwest. Patients completed a self-administered survey assessing sociodemographic and health information, loneliness, illicit opioid use, and MMT characteristics. Logistic regressions were estimated to examine the link between patient odds of illicit opioid use in the past month and perceived loneliness. Results: Patient gender moderated the association between illicit opioid use and loneliness such that severe loneliness was associated with higher odds of using illicit opioids among women (OR = 3.00, 95% CI [1.19, 7.57], p=.020) but lower odds of using illicit opioids among men (OR = 0.35, 95% CI [0.14, 0.87], p=.024), accounting for age, marital status, work status, depressive symptoms, and MMT characteristics (treatment episode, treatment duration, and methadone dose). Conclusions/importance: This study underscores the importance of considering loneliness in the management of OUD. Routine clinical care and treatment may benefit from strategies to build and sustain social connections that support long-term recovery among MMT patients.

Older adults' empathy may shape the frequency and types of support that they exchange with their social partners as well as the implications of these exchanges. This study drew on the Daily Experiences and Well-being Study, which included adults aged 65 and over and tracked them across 5 to 6 days using mobile phone surveys. Participants (n = 293) rated their empathy and reported their daily support exchanges (e.g., emotional support, instrumental support, advice) as well as mood. Findings showed that more empathic older adults provided each type of support more often. They also received more emotional support than less empathic older adults. Moreover, older adults' empathy moderated the associations between providing support and their daily mood. More empathic older adults maintained their mood regardless of whether they provided support. By contrast, less empathic older adults reported reduced positive mood on days when they provided emotional support and increased positive mood when they provided instrumental support. Greater empathy is associated with more frequent support exchanges; however, more empathic older adults appear immune to such exchanges in terms of their mood. Interestingly, less empathic older adults may find providing emotional support draining but instrumental support rewarding, probably because they are less equipped to cope with others' emotions.
RESUMO
Background: Greater feelings of purpose in life are associated with better health and may reduce the negative impact of chronic stress. Yet little is known about how purpose in life may buffer the negative effects of caregiving, a common chronic stressor in middle and later life. Methods: This cross-sectional study utilized a U.S. sample of 315 spousal caregivers and their partners with functional disability drawn from the 2011 National Health and Aging Trends Study and National Study of Caregiving to examine how both parties' perceptions of purpose in life are associated with caregivers' emotional and physical caregiving difficulties. We also evaluated whether care recipients' purpose in life moderates the association between caregivers' purpose in life and care-related difficulties. Finally, we considered whether these links differed by caregiver gender. Models controlled for caregivers' sociodemographics, care tasks, support resources, valued activity participation, and each care partner's health conditions. Results: Caregivers' greater purpose in life was significantly linked to fewer physical caregiving difficulties. Caregivers' greater purpose in life was significantly associated with fewer emotional care-related difficulties among caregiving wives and when care recipients' purpose in life was low. Conclusions: Although the associations between purpose in life and care-related difficulties are likely bidirectional, purpose in life may represent an important resource for combating the adverse consequences of caregiving. This study highlights the value of considering personal resources and their implications for caregivers' well-being within a dyadic context.

Relationships with parents have significant implications for well-being throughout the lifespan. At midlife, these ties are situated within both developmental and family contexts that often involve the adult offspring's spouse. Yet, it is not known how ties with aging parents are related to psychological well-being within middle-aged couples. This study examined how middle-aged wives' and husbands' views of the current quality of relationships with their own parents (positive and negative) are linked to their own and their partner's psychological well-being. Using a sample of 132 middle-aged couples from Wave 1 of the Family Exchanges Study, we estimated actor-partner interdependence models to evaluate these dyadic associations while controlling for each spouse's marital satisfaction. Both actor and partner effects were observed. With respect to actor effects, wives who reported more negative relationship quality with their own parents had elevated depressive symptoms and lower life satisfaction. Husbands who reported more negative relationship quality with their own parents had lower life satisfaction. In terms of partner effects, husbands had lower depressive symptoms and greater life satisfaction when wives reported more positive relationship quality with their own parents. Finally, the link between wives' positive ties with parents and husbands' lower depressive symptoms was intensified when husbands had less positive relationships with their own parents. Findings suggest that relationship quality with wives' aging parents has implications for both spouses' well-being and may serve as a critical social resource for husbands.

An important pathway by which relationships influence health may involve how people cope with interpersonal tensions. This study examined whether same day and prior day avoidance and engagement in arguments are differentially associated with self-reported well-being (emotional, physical) and diurnal cortisol patterns. Participants from Wave 2 of the National Study of Daily Experiences (NSDE; N =1512; ages 33-84, 57% women), completed daily phone interviews for eight consecutive days and provided useable saliva samples that were assayed for cortisol for four of those days at specific times: waking, 30 minutes after waking, before lunch, and bedtime. Multilevel models revealed same day arguments were associated with lower well-being (higher negative affect, lower positive affect) than same day avoidance or no tension. In contrast, previous day avoidance was associated with lower next day well-being (higher negative affect, more physical symptoms) and higher next day cortisol than having no interpersonal tension the previous day. Arguments have greater same day consequences for well-being, whereas avoided arguments have greater next day consequences, which may indicate delayed effects of avoidance.
RESUMO
OBJECTIVE: Studies have shown that contact with friends enhances emotional health, but little is known about whether friends influence cardiovascular health. This study investigated (a) whether encounters with friends and the quality of these encounters were associated with cardiovascular reactivity in everyday life and (b) whether these associations varied by race. METHOD: Participants were from the Stress and Well-being in Everyday Life Study which included Black (n = 76; aged = 34-76) and White (n = 87, aged = 34-91) adults residing in the United States. Participants provided background and social network information in a baseline interview, followed by a 4-day ecological momentary assessment in which they reported social encounters every 3 hr. Concurrently, participants wore an electrocardiogram monitor which collected physiological data in real time. To assess cardiovascular reactivity, heart rate variability (HRV) was analyzed. RESULTS: Multilevel models revealed that at times when individuals encountered friends (particularly positive encounters), they exhibited a momentary reduction in HRV (within-person association). But those with more friend encounters during the study period (particularly positive encounters) had higher HRV than those with fewer friend encounters during the study period (between-person association). These links were observed only among Black adults, but not among White adults. CONCLUSIONS: This study contributes to the conceptual model of social integration and enriches the literature on racial disparities in cardiovascular health from a social perspective. Findings highlight the implications of engagement with friends for momentary cardiovascular reactivity and suggest that friends may be more salient for Black adults' cardiovascular health.

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 the effects of interpersonal stress in daily life. Helping older adults foster these ties may improve their mental health. RESEARCH DESIGN AND METHODS: Participants (nâ =â 313) aged 65+ completed a baseline interview reporting duration and contact frequency of their closest ties. Then, participants completed ecological momentary assessments every 3 hr for 5-6 days, reporting their social encounters and mood. RESULTS: We classified ties according to duration (10+ yearsâ =â long vs shorter duration) and frequency of contact (at least once a monthâ =â 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.

OBJECTIVE: Perseverative thinking (e.g., worry/rumination) is a common response to stress, and can be detrimental to well-being. Sleep may represent an important mechanism by which perseverative thinking is disrupted or amplified from day to day. This study examined the associations between older adults' everyday worry, rumination, and sleep. METHODS: Older adults (N = 270) aged 65-89 completed a baseline interview and morning and evening assessments each day for 5-6 days. Every morning, they indicated their worry toward the day and their sleep duration and disturbances the prior night. Every evening, they rated worry and rumination experienced that day. RESULTS: Multilevel models showed that perseverative thinking predicted worse sleep (i.e., fewer hours of sleep) at the between-person level (B = -0.29, p = .004) but better sleep (i.e., fewer sleep disturbances) at the within-person level (Bs < -0.18, ps < .003). At the within-person level, more hours of sleep (B = -0.06, p = .04) and fewer sleep disturbances (B = 0.10, p < .001) predicted less worry the next morning. Prior night's worry predicted greater next morning's worry, but this association was significant only when older adults reported fewer-than-usual hours of sleep (B = 0.24, p < .001), not when they reported more-than-usual hours of sleep (B = 0.04, p = .61). CONCLUSION: Findings suggest that worry and rumination are intimately linked with sleep and highlight the protective role that better sleep may play in reducing older adults' everyday perseverative thinking.

OBJECTIVES: Social contact may alleviate loneliness, but little is known about within-person daily fluctuations in loneliness and social encounters. Older adults who feel lonely may engage in different modes of social contact (in-person, phone, digital). This study asked how different forms of contact are associated with loneliness throughout the day. METHODS: Participants were 313 community-dwelling older adults (aged 65-90). They completed ecological momentary assessments reporting on their social encounters (e.g., type of social partner, mode of contact) and their loneliness every 3 hr for 5-6 days. We differentiated close social ties from ties not identified as close (i.e., weak ties). RESULTS: We examined within-person effects using multilevel models. Findings revealed that momentary loneliness predicted a greater likelihood of phone contact in the next 3 hr. However, only in-person contact was associated with lower levels of loneliness. Regarding close and weak ties, momentary loneliness was associated with more in-person and phone contact with close ties, yet fewer in-person contacts with weak ties. In-person contact with both close and weak ties predicted lower levels of loneliness. DISCUSSION: Although older adults engage in both in-person and phone contact when they feel lonely, it appears that only in-person contact may reduce loneliness. Digital contact was not widely adopted as a response to momentary loneliness among these older adults. Findings underscore older adults' willingness to maintain regular contact with close ties. Interventions addressing older adults who are lonely may consider innovative approaches to increase in-person contact.

OBJECTIVES: Women tend to ruminate more than men, and are generally more hypervigilant to the emotions of others in order to maintain positive social ties. Thus, compared to men, women may ruminate more when their social partners have greater life stresses. However, the literature on stressful events typically focuses on individuals' experiences and perceptions of stressors experienced by specific social ties such as spousal partners and adult children. The purpose of this study was to examine links between perceptions of a broad array of family and nonfamily social partner stresses and daily rumination among older men and women. METHODS: Adults aged 65 and older (N = 293, 55% women) completed baseline assessments of family and nonfamily life stressors and 5-6 consecutive nightly assessments regarding rumination, interpersonal tensions, worries, and support provision. RESULTS: Multilevel structural equation models revealed that perceptions of greater family and nonfamily life stressors were associated with greater rumination. The links between family stress and rumination varied by gender: family stress was related to greater rumination among women and not men. Moreover, among women, family and nonfamily stress-rumination links were accounted for by greater daily worries about others, and among men, the nonfamily stress-rumination link was due to greater interpersonal tensions as well as daily worries. DISCUSSION: These findings may be due in part to gender role socialization and women's greater kin-keeping and investment in family ties.

BACKGROUND AND OBJECTIVES: Spouses with concordant (i.e., similar) drinking behaviors often report better quality marriages and are married longer compared with those who report discordant drinking behaviors. Less is known regarding whether concordant or discordant patterns have implications for health, as couples grow older. The present study examined whether drinking patterns among older couples are associated with mortality over time. RESEARCH DESIGN AND METHODS: The Health and Retirement Study (HRS) is a nationally representative sample of individuals and their partners (married/cohabiting) over age 50 in the United States, in which participants completed surveys every 2 years. Participants included 4,656 married/cohabiting different-sex couples (9,312 individuals) who completed at least 3 waves of the HRS from 1996 to 2016. Participants reported whether they drank alcohol at all in the last 3 months, and if so, the average amount they drank per week. Mortality data were from 2016. RESULTS: Analyses revealed concordant drinking spouses (both indicated they drank in the last 3 months) survived longer than discordant drinking spouses (1 partner drinks and the other does not) and concordant nondrinking spouses. Analysis of average drinks per week showed a quadratic association with mortality such that light drinking predicted better survival rates among individuals and their partners compared with abstaining and heavy drinking. Further, similar levels of drinking in terms of the amount of drinking were associated with greater survival, particularly among wives. DISCUSSION AND IMPLICATIONS: This study moves the field forward by showing that survival varies as a function of one's own and one's partner's drinking.

BACKGROUND: Dyslipidemia, which is characterized by an unfavorable lipid profile, is a key risk factor for cardiovascular disease (CVD). Understanding the relationships between epigenetic aging and lipid levels may help guide early prevention and treatment efforts for dyslipidemia. METHODS: We used weighted linear regression to cross-sectionally investigate the associations between five measures of epigenetic age acceleration estimated from whole blood DNA methylation (HorvathAge Acceleration, HannumAge Acceleration, PhenoAge Acceleration, GrimAge Acceleration, and DunedinPACE) and four blood lipid measures (total cholesterol (TC), LDL-C, HDL-C, and triglycerides (TG)) in 3,813 participants (mean age = 70 years) from the Health and Retirement Study (HRS). As a sensitivity analysis, we examined the same associations in participants who fasted prior to the blood draw (n = 2,531) and in participants who did not take lipid-lowering medication (n = 1,869). Using interaction models, we also examined whether demographic factors including age, sex, and educational attainment modified the relationships between epigenetic age acceleration and blood lipids. RESULTS: After adjusting for age, race/ethnicity, sex, fasting status, and lipid-lowering medication use, greater epigenetic age acceleration was associated with lower TC, HDL-C, and LDL-C, and higher TG (p < 0.05), although the effect sizes were relatively small (e.g., < 7 mg/dL of TC per standard deviation in epigenetic age acceleration). GrimAge acceleration and DunedinPACE associations with all lipids remained significant after further adjustment for body mass index, smoking status, and educational attainment. These associations were stronger in participants who fasted and who did not use lipid-lowering medication, particularly for LDL-C. We observed the largest number of interactions between DunedinPACE and demographic factors, where the associations with lipids were stronger in younger participants, females, and those with higher educational attainment. CONCLUSION: Multiple measures of epigenetic age acceleration are associated with blood lipid levels in older adults. A greater understanding of how these associations differ across demographic groups can help shed light on the relationships between aging and downstream cardiovascular diseases. The inverse associations between epigenetic age and TC and LDL-C could be due to sample limitations or non-linear relationships between age and these lipids, as both TC and LDL-C decrease faster at older ages.
