Two-Wave Dyadic Analysis of Marital Quality and Loneliness in Later Life: Results From the Irish Longitudinal Study on Ageing

Sympathetic arousal among depressed college students: Examining the interplay between psychopathology and social activity

Depressed individuals exhibit altered sensitivity to both positive and negative social contact, and may not reap the same psychological and emotional benefits to socializing as non-depressed individuals. Although depressive symptoms and loneliness predict social withdrawal and decreased pleasure, little is currently understood about immediate affective arousal dynamics during real-time socializing. Using a novel ambulatory protocol that tracked both objective features of affective arousal (electrodermal activity) and subjective valence (self-reported) during college students' social interactions, we evaluated the moderating role of depression and loneliness symptoms on the associations between socializing with others (specifically, with a romantic partner, a close friend, or a group of friends) and the arousal and valence dimensions of affect. Among a racially and ethnically diverse sample of 118 college students (64% African American/Black/Continental African, 20% Latinx, 8% Asian, and 8% White) recruited from a large, predominantly White Midwestern university, those lower in depression and loneliness symptomatology evinced decreased average arousal (Β = -0.10, SE = 0.04, p < .01) when in relaxed and intimate socializing contexts (e.g., with a romantic partner and a close friend), consistent with the idea that these contexts facilitate important opportunities for psychological rest and recovery. Those lower in depression and loneliness symptoms also showed higher average arousal when socializing in the energizing context of being with a group of friends. Overall, the results suggest psychopathology is reflected in patterns of sympathetic arousal when socializing, with more depressed and lonely individuals generally feeling worse while receiving fewer psychophysiological rewards in multiple socializing contexts.

Improvement of Social Isolation and Loneliness and Excess Mortality Risk in People With Obesity

Importance

Individuals with obesity experience markedly higher levels of social isolation and loneliness than those without obesity, but little is known about whether improvement of social isolation or loneliness might attenuate obesity-related excess risk of mortality.

Objective

To investigate whether improvement of social isolation or loneliness is associated with lower obesity-related excess risk of mortality.

Design, Setting, and Participants

This cohort study included individuals without cancer or cardiovascular disease (CVD) at baseline from the UK Biobank with follow-up beginning in March 2006 and ending in November 2021.

Main Outcomes and Measures

All-cause, cancer-related, and CVD-related mortality were estimated.

Results

A total of 398 972 participants were included in this study (mean [SD] age, 55.85 [8.08] years; 220 469 [55.26%] women; 13 734 [3.44%] Asian, 14 179 [3.55%] multiracial, and 363 685 [91.16%] White participants). Overall, 93 357 (23.40%) had obesity, and 305 615 (76.60%) did not. During a median (IQR) follow-up of 12.73 (12.01-13.43) years, a total of 22 872 incident deaths were recorded. Compared with participants with obesity with an index of 2 or greater for social isolation, the multivariable adjusted hazard ratios (HRs) for all-cause mortality were 0.85 (95% CI, 0.79-0.91) and 0.74 (95% CI, 0.69-0.80) for participants with obesity and a social isolation index of 1 and 0, respectively (P for trend < .001); compared with participants with obesity and an index of 2 for loneliness, the HRs and 0.97 (95% CI, 0.89-1.06) and 0.86 (95% CI, 0.79-0.94) for participants with obesity and a loneliness index of 1 and 0, respectively (P for trend < .001). As the index of social isolation and loneliness went from highest to lowest, the HR for all-cause mortality decreased by 36% and 9%, respectively, in people with obesity compared with people without obesity using the multivariable model. Social isolation was ranked higher than loneliness, depression, anxiety, and lifestyle-related risk factors including alcohol, physical activity, and healthy diet for estimating the risks of all-cause mortality, cancer-related mortality, and CVD-related mortality.

Conclusions and Relevance

In this cohort study of UK Biobank participants, a lower index of social isolation or loneliness was associated with a decreased risk of all-cause mortality among people with obesity, and improvement of social isolation and loneliness attenuated obesity-related excess risk of all-cause mortality.

A Life Course, Intergenerational Perspective on Loneliness

The present study relied on 15 dyads of adult children and their older parent to better understand intergenerational family relations from a life course perspective. Interviews were analyzed relying on qualitative thematic analysis, identifying similarities and differences within and between interviews and dyads. Our analysis resulted in three major themes. The first concerns the important role of intergenerational family relation as a means to define and conceptualize the experiences of loneliness and ways of coping with loneliness. The second theme concerned intergenerational relations as a cause (and at times a remedy) of loneliness. The third theme concerns the ability of the dyad's members to reflect on the level of loneliness of the other member in the intergenerational dyad. The findings stress the importance of intergenerational family relations throughout the life course and highlight the importance of adopting an intergenerational lens as a possible means to address loneliness.

Dyadic loneliness, age, and cognitive functioning among midlife and older Black couples

Objectives: Within marriages, loneliness has been linked with individuals' own and their partners' cognitive health. Yet little research has situated Black older adults within a relational, dyadic context.Method: This study analyzed longitudinal dyadic data from the Health and Retirement Study (2010-2016; n = 1270 participants from 635 couples) from both partners in opposite-sex midlife and older couples where at least one partner reported being Black or African American.Results: Results indicated (1) husbands' loneliness was associated with worse cognitive functioning 4 years later for wives who had high baseline cognitive functioning themselves; (2) wives' loneliness was associated with worse cognitive functioning 4 years later only for oldest-old husbands; and (3) wives' cognitive functioning was associated with slower increases to husbands' loneliness 4 years later.Conclusion: Findings indicate that loneliness has dyadic consequences for cognitive functioning among older Black couples, but that context is crucial for determining who is at greatest risk of harmful repercussions from a partner's loneliness.

Longitudinal Dyadic Associations Between Loneliness and Cognition Among Older Couples in the United States

OBJECTIVES

Loneliness is associated with diminished health and cognition for older individuals. However, little research has examined dyadic loneliness-that is, loneliness of both partners in a relationship-and its potential consequences for cognitive functioning among both spouses, nor whether one partner's cognition may affect both partners' loneliness over time.

METHODS

We analyze 3-wave dyadic Health and Retirement Study data (2010-2020; N = 1,061 dyads) to determine (a) whether loneliness predicts participants' own and/or their partners' episodic memory and verbal fluency over 8 years, and (b) whether cognitive functioning predicts older spouses' own or their partners' loneliness over the same period.

RESULTS

Loneliness predicted participants' own and their partners' loneliness at follow-up, at both time points. Loneliness was also associated with own episodic memory at follow-up, but not with verbal fluency. Episodic memory and verbal fluency predicted one another over time. Neither episodic memory nor verbal fluency predicted loneliness at follow-up. Significant dyadic mediation was established such that Time 1 loneliness was linked with partner's Time 3 episodic memory via that partner's Time 2 loneliness.

DISCUSSION

Lonelier older adults displayed worse trajectories of episodic memory over time, yet poor memory did not precede changes to loneliness. Further, having a lonely partner was linked with poorer episodic memory 8 years later, indicating that both one's own and-to a lesser extent-a partner's emotional well-being may be consequential for maintaining cognitive functioning with age. Associations were more clearly established with episodic memory than with verbal fluency, suggesting potential domain-specific effects of loneliness.

Loneliness and HbA1c among older Irish couples: Retirement as life stage context

Loneliness is an important determinant of health and mortality among the aging population, including for cardiometabolic health. Yet research has largely focused on individual experiences of loneliness, rather than taking intimate relationships into account. However, recent studies have highlighted that loneliness of a partner may have implications for one's own health and well-being as well. Indeed, this is particularly true among older couples, as life events and shifting time horizons (e.g., retirement, reduced social networks) can lead to greater prominence and salience of one's closest relationships. This study uses dyadic structural equation modeling (SEM) to estimate actor-partner interdependence models (APIM) examining associations between loneliness and HbA1c levels among 1331 older married couples from The Irish Longitudinal Study on Aging (TILDA, 2009-2011). Furthermore, we test whether any such actor or partner effects vary by employment status. Results indicated that one's own loneliness was not significantly linked with HbA1c, irrespective of employment status. However, loneliness of a dyadic partner was significantly associated with elevated HbA1c among retired persons only. These findings underscore that relationship and life course context are crucial when considering the dyadic implications of loneliness for health among the older population.

Loneliness and diurnal cortisol levels during COVID-19 lockdown: the roles of living situation, relationship status and relationship quality

Loneliness and social isolation have become increasing concerns during COVID-19 lockdown through neuroendocrine stress-reactions, physical and mental health problems. We investigated living situation, relationship status and quality as potential moderators for trait and state loneliness and salivary cortisol levels (hormonal stress-responses) in healthy adults during the first lockdown in Germany. N = 1242 participants (mean age = 36.32, 78% female) filled out an online questionnaire on demographics, trait loneliness and relationship quality. Next, N = 247 (mean age = 32.6, 70% female) completed ecological momentary assessment (EMA), collecting twelve saliva samples on 2 days and simultaneously reporting their momentary loneliness levels. Divorced/widowed showed highest trait loneliness, followed by singles and partnerships. The latter displayed lower momentary loneliness and cortisol levels compared to singles. Relationship satisfaction significantly reduced loneliness levels in participants with a partner and those who were living apart from their partner reported loneliness levels similar to singles living alone. Living alone was associated with higher loneliness levels. Hierarchical linear models revealed a significant cross-level interaction between relationship status and momentary loneliness in predicting cortisol. The results imply that widowhood, being single, living alone and low relationship quality represent risk factors for loneliness and having a partner buffers neuroendocrine stress responses during lockdown.

Actor and Partner Effect of Loneliness on Episodic Memory and Verbal Fluency: A Dyadic Multilevel Analysis of Romantic Couples Across 28 Countries

OBJECTIVES

There is evidence that loneliness is detrimental to cognitive health. Most studies, however, do not consider the association between loneliness and cognition in the context of close relationships, such as a spouse or romantic partner. This study examines loneliness, experienced by both the individual and their romantic partner, and cognitive performance.

METHODS

Data were from 24,689 opposite-sex couples (49,378 participants) from 28 countries in the Survey of Health, Aging and Retirement in Europe. Each couple participant reported loneliness and completed memory and verbal fluency tasks. A multilevel sex-stratified analysis was used to account for the nested data structure and evaluate actor and partner effects of loneliness on cognitive performance for male and female partners.

RESULTS

Consistent with the literature, there were small actor effects of loneliness on memory and verbal fluency for both males and females: A person's own loneliness was associated negatively with their cognitive performance on both tasks. There were also small partner effects: A person with a partner who was lonely tended to have worse cognitive performance above and beyond their own loneliness. Actor and partners effects were similar for male and female partners, replicated in most countries, and generally held controlling for age, education, household size, and disease burden. For memory, loneliness effects were slightly stronger among older participants.

DISCUSSION

Both the experience of loneliness and loneliness of a partner have a negative association with cognitive health.

Couple Analysis in the National Social Life, Health, and Aging Project

OBJECTIVES

Marital and intimate partner relationships are some of the most important social ties that shape older adults' health and well-being. This paper provides analytic guidelines for the couple data in Round 2 (2010-2011) and Round 3 (2015-2016) of the National Social Life, Health, and Aging Project (NSHAP) to encourage more research on marriage and partnership in late life.

METHOD

First, we describe the recruitment of couples and outline how to identify partners in the data sets. Second, we provide descriptive information about the couple sample. Third, we offer guidance for analyzing the dyadic data cross-sectionally and longitudinally.

RESULTS

Round 2 interviewed all primary respondents and a sample of their current cohabiting partners and spouses (n = 955 couples). In Round 3, NSHAP reinterviewed the primary respondents and partners who participated in Round 2 (Cohort 1; n = 621 couples) and recruited a new sample of age-eligible adults along with any cohabiting romantic partners (Cohort 2; n = 766 couples). Couples can be identified using a household ID variable in Round 2 and a partner ID variable in Round 3. Demographic characteristics of the couple sample vary by round and cohort.

DISCUSSION

Researchers can use data from either round to conduct cross-sectional dyadic analyses to examine issues faced by older couples. A common strategy for couple analysis is the actor-partner interdependence model. With 2 rounds of couple-level data, researchers may consider using cross-lagged models in their research.

Impact of the COVID-19 Pandemic on Loneliness and Social Isolation: A Multi-Country Study

The COVID-19 global pandemic and subsequent public health social measures have challenged our social and economic life, with increasing concerns around potentially rising levels of social isolation and loneliness. This paper is based on cross-sectional online survey data (available in 10 languages, from 2 June to 16 November 2020) with 20,398 respondents from 101 different countries. It aims to help increase our understanding of the global risk factors that are associated with social isolation and loneliness, irrespective of culture or country, to support evidence-based policy, services and public health interventions. We found the prevalence of severe loneliness was 21% during COVID-19 with 6% retrospectively reporting severe loneliness prior to the pandemic. A fifth were defined as isolated based on their usual connections, with 13% reporting a substantial increase in isolation during COVID-19. Personal finances and mental health were overarching and consistently cross-cutting predictors of loneliness and social isolation, both before and during the pandemic. With the likelihood of future waves of COVID-19 and related restrictions, it must be a public health priority to address the root causes of loneliness and social isolation and, in particular, address the needs of specific groups such as carers or those living alone.

Own health, spousal health and transitions in loneliness among middle-aged and older adults in China

This study examines the effects of own and spousal health on transitions in loneliness over time among married middle-aged and older adults in China, and explores the possible gender differences in these effects using data from the three waves of the China Health and Retirement Longitudinal Study (2011–2015). The sample includes 6,422 men and 6,391 women who were married and aged 45 and older at the baseline survey. Middle-aged and older adults with poorer physical and emotional health statuses are more likely to transition into and less likely to transition out of loneliness in a two-year period. Spouse's emotional health also affects both types of transition in loneliness and spouse's functional limitation affects transition into loneliness through spouse's emotional health. In addition, for married men, their own functional limitation is significantly associated with their transitions into and out of loneliness. For married women, their spouse's functional limitation is significantly associated with their transition into loneliness and this is mainly through its association with spouse's emotional health. Also, for married women, their spouse's emotional health is significantly associated with their transition out of loneliness. Social interventions to reduce feelings of loneliness need to take a couple approach and consider both spouses’ health problems and how they may affect their daily activities and their interactions with each other and with others.

‘The care circle consists of me.’ Loneliness and social isolation for older male spousal care-givers. A qualitative study

Whilst loneliness and social isolation amongst older care-givers are becoming increasingly recognised, little is known about how these concepts impact on specific sub-groups of care-givers, such as older males. In the current study, we aimed to gain a better understanding of the experiences of loneliness and social isolation amongst older spousal male care-givers. Semi-structured interviews were undertaken with 24 participants, caring for a spouse/partner with a long-term chronic condition. After thematic analysis of the data, three themes were identified: dwindling social interactions, loneliness in the spousal relationship, and living with loneliness and social isolation. Study findings suggest that opportunities for social interactions gradually ‘dwindled’ due to a reluctance by older male care-givers to leave their spouse/partner at home alone, to accept offers of help or respite, or to attend social events without their spouse/partner. Consequently, social isolation increased. Feelings of physical and emotional loneliness were evident, and the loss of spousal companionship (such as loss of conversation and shared interests) increased loneliness. Individualised coping strategies were adopted including focusing on moments of positivity, talking to others and using prescribed medication. Findings provide insight into the experience of loneliness and social isolation for many older male spousal care-givers. This may facilitate a better understanding of older male care-givers’ support needs in addressing loneliness and social isolation, and should help to inform the development of targeted support services for this population.

The prevalence and predictors of loneliness in caregivers of people with dementia: findings from the IDEAL programme

OBJECTIVES

To establish the prevalence of loneliness among family caregivers of people with dementia and to identify potential risk factors for loneliness.

METHODS

Using data from the baseline wave of the Improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort study, we examined loneliness in 1283 family caregivers of people with mild-to-moderate dementia living in Great Britain. Multinomial regression was used to examine the relative influence of a series of risk factors for caregiver loneliness.

RESULTS

Almost half, 43.7%, of caregivers reported moderate loneliness and 17.7% reported severe loneliness. Greater social isolation and increased caregiving stress were linked with both moderate and severe loneliness. Better quality of relationship with the person with dementia along with increased levels of well-being and life satisfaction were associated with a lower relative risk of reporting both moderate and severe loneliness.

DISCUSSION

This study examines the prevalence and predictors of loneliness in a large sample of family caregivers of people with dementia. Notably over two-thirds of caregivers in our sample reported feeling lonely. Interventions aimed at reducing caregiving stress and supporting meaningful relationships may go some way towards helping to reduce loneliness.

Dyadic Loneliness and Changes to HbA1c Among Older US Couples: The Role of Marital Support as Stress Buffer

Objectives: Both experiencing loneliness and having a lonely partner can be psychosocial stressors, with implications for health. Yet, marital support may buffer against the cardiometabolic effects of loneliness. This study examines (1) whether own and/or partner's loneliness predict changes in HbA1c over 4 years and (2) whether marital support moderates these effects. Methods: Actor-partner interdependence models analyzed data from 1,854 older couples who provided psychosocial and biomarker data at two timepoints (2008/2012 or 2010/2014) of the Health and Retirement Study. Results: Neither partner's loneliness predicted changes in HbA1c overall. However, significant interactions indicated that both own baseline loneliness and partner's baseline loneliness predicted significant increases to HbA1c over 4 years among those who reported below-average marital support. Discussion: Both the experience of loneliness and loneliness of a dyadic partner may have longitudinal consequences for cardiometabolic health. However, these effects are contingent upon perceived quality of the marriage, specifically marital support.

Your friends, my friends, and our family: Informal social participation and mental health through the lens of linked lives

RATIONALE

Social participation is an important predictor of individual health outcomes, but few studies have examined it in the context of marriage relationships, even though the social lives of spouses are inextricably linked.

OBJECTIVE

To examine whether individuals' mental health is associated with their spouse's contact with friends and family.

METHODS

Using dyadic data from adults aged 50 and above in the Health and Retirement Study (N = 5030 couples), I examine whether individuals' mental health is associated with their spouse's contact with friends and family (i.e., partner effects) through a longitudinal actor-partner interdependence model. In addition, I test for the presence of gender differences in these effects. Both depressive symptoms and binge drinking are used as measures of mental health to account for the different ways in which men and women may express psychological distress.

RESULTS

Results show partial evidence that spousal contact with friends and family are associated with one's own mental health outcomes, and that within-dyad discrepancies in informal social participation may be detrimental to mental well-being.

CONCLUSIONS

These findings highlight the importance of understanding the dynamics between social participation and health through the lens of "linked lives", especially for married couples.

Spousal Support, Spousal Strain, and Loneliness in Older Mexican Couples

OBJECTIVES

A growing body of research has identified factors related to loneliness among older adults. Fewer have investigated predictors of loneliness within married couples. This analysis investigates how spousal support and strain relate with loneliness within older couples (age 50+), and whether these associations are modified by functional limitation. The study focuses on Mexico, a country experiencing rapid aging occurring alongside historically limited institutional support for older adults, and where traditional gender roles extend to marriage.

METHODS

The analytic sample consisted of 3,584 husband-wife dyads from the 2012 and 2015 Mexican Health and Aging Study. Loneliness was measured using the Three-Item Loneliness Scale. Associations between spousal support, strain, and loneliness were estimated within husband-wife dyads using the Actor-Partner Interdependence Model.

RESULTS

Experiencing more spousal support was associated with less loneliness, whereas experiencing spousal strain was associated with more loneliness 3 years later among married adults. The associations between spousal support/strain and loneliness were stronger among husbands with limitations in activities of daily living (ADL) when compared to their counterparts without ADL limitations.

DISCUSSION

Among married adults, spousal support and strain may be important factors to understand loneliness within marriage. Effects should be interpreted within the context of functional limitation.

The Contribution of Stressful Marital Interactions to Loneliness and Health across Mid-life and Later Adulthood

Although past research has noted longitudinal, and sometimes bi-directional, associations between marital interactions, loneliness, and physical health, previous work has not identified long-term associations and differential associations over life-course stages (i.e., mid-life and later adulthood). Utilizing a life-course stress process perspective and a sample of 250 couples in enduring marriages over 17 years (2001-2017), a structural equation model within a dyadic framework assessed the unique influences of stressful marital interactions on loneliness and physical health and the variation in bi-directional influences of loneliness and physical health over time. Marital interactions were relatively stable across life stages, yet marital interactions appear to influence loneliness and physical health. Notable distinctions were evident across life stages (from mid-life to later adulthood and then within later adulthood). Findings are discussed with an emphasis on the implications for health promotion and prevention programs targeting couples' quality of life in later years.

Cynical Hostility and Loneliness in Older Adult Married Couples: An Indirect Effect Through Friendships

OBJECTIVES

Cynical hostility is a cognitive schema according to which people cannot be trusted, and it has associations with individuals' loneliness. The present study takes a dyadic approach to examine whether cynical hostility is related to one's own and their spouse's loneliness. We further explore whether friendship factors serve as a mediator between individuals' and spouses' cynical hostility and loneliness.

METHOD

We used 2 waves of the Health and Retirement Study (N = 1,065 couples) and Actor-Partner Interdependence Models (APIMs) with mediation to examine the proposed model. Mediation was tested with the construction of path models and significance levels were reached using bootstrapping.

RESULTS

For both husbands and wives, cynical hostility was significantly associated with loneliness. Husband's loneliness was also significantly associated with his wife's cynical hostility, but wife's loneliness was not associated with her husband's cynical hostility. We further found that the association between wife's own cynical hostility and loneliness was mediated by lower levels of contact with, and support from friends. Friendship factors did not serve as mediators for husbands.

DISCUSSION

Husbands and wives who have higher levels of cynical hostility may be more vulnerable to loneliness. High levels of cynical hostility in women may be related to deficits in their quantity and quality of friendship, and thus be associated with loneliness. Men who are married to women with a higher level of cynical hostility may experience increased loneliness, but this relationship is not explained by men's friendships.

Loneliness is associated with the subjective evaluation of but not daily dynamics in partner relationships

Loneliness describes a perceived deficiency in quantitative or qualitative aspects of individuals’ social relationships. Whereas the health-related consequences of loneliness are well-documented, surprisingly little is known about its interpersonal features and its consequences for relationship outcomes. In the present study, we investigated the association between loneliness and relationship experiences in partner relationships with a sample of 937 individuals from 480 mixed-sex couples. By employing actor-partner interdependence models and dyadic cross-lagged moderated multilevel models, we found higher loneliness to be robustly related to (a) lower relationship satisfaction for both oneself and the partner, (b) more self-reported, but not partner-reported conflicts, (c) lower average levels of one’s own, but not the partner’s closeness, and (d) less own self-disclosure. In contrast, loneliness was not associated with (a) sexual contact frequency, (b) average levels of physical affection, or (c) the daily dynamics between closeness and self-disclosure/physical affection. Thus, the results of the present study indicated that loneliness is primarily associated with the perception of the partner relationship but not its rather objective features or daily dynamics.

Do “His” and “Her” Marriages Influence One Another? Contagion in Personal Assessments of Marital Quality among Older Spouses over a Four-Year Span

Husbands and wives differ in their evaluations of marital quality, with “his” marriage typically proving better than “her” marriage. However, spouses’ perceptions of marital quality tend to be significantly correlated with one another. Prior research has addressed the existence and implications of gender differences in marital quality but has focused less on spouses’ similarities in their perceptions. In particular, prior studies have not examined the extent to which spouses’ assessments of marital quality may be reciprocally related. In short, do his and her marriages influence one another? This study analyzes longitudinal dyadic data from 209 older married couples who participated in the first two waves of the Disability and Use of Time supplement to the Panel Study of Income Dynamics (2009–2013). Two-wave lagged models tested emotional and social contagion theory by examining whether husbands’ and wives’ reports of marital quality at baseline predicted both spouses’ marital quality after four years. Results indicated that (a) husbands reported better marital quality than their wives in both 2009 and 2013; (b) for both husbands and wives, baseline marital quality was significantly related with one’s own and one’s partner’s marital quality four years later; and (c) there were no differences in effects according to gender. These findings offer support for the framework of his and her marriage as well as emotional and social contagion theory.
