Abstract Prior research on the causality and directionality between disease and functional limitations is ambiguous. The current study used longitudinal monozygotic twin data to test both directions linking disease burden and functional limitations in middle-aged and older adults, controlling for genetic and familial factors. We also examined potential moderation by psychological well-being. The Twins sub-sample from the first two waves of the longitudinal Midlife in the United States (MIDUS) study was used (Wave 1: 1995-1996, Wave 2: 2004-2006). Only monozygotic twins (N = 713) were included in analyses. In separate multi-level models, we examined disease burden at MIDUS 2 predicted by functional limitations at MIDUS 1 and MIDUS 2 functional limitations predicted by disease burden at MIDUS 1. Disease burden and functional limitations at MIDUS 2 varied substantially within families. There was no within-family association of earlier functional limitations with change in later disease burden (b = .40, p = .39), but there was a within-family association such that the twin with higher baseline disease burden had a greater increase in functional limitations than his/her co-twin (b = .06, p = .02). Well-being was not a moderator in either model. We found support for a potentially causal association between earlier disease burden and later increases in functional limitations, consistent with the Disablement Process Model. Sensitivity analyses confirm the detected within-family effect. Possible mechanisms linking disease burden and functional limitations are discussed as potential targets for future research.

Abstract Social media platforms allow people to connect and share content online (e.g., Facebook, Twitter). Although older adults are becoming more frequent users of social media, there continue to be mixed views on whether social media positively or negatively impacts well-being. Past studies have mainly focused on cross-sectional analyses for individual differences. However, both the time spent on social media and one’s affect can fluctuate on a daily basis. Thus, it is important to understand how the relationship between daily social media usage and affect varies within individuals from day to day. The current study adds to the literature by examining whether daily variations in time spent with social media are related to daily positive and negative affect and whether there are age differences in these relationships. The current study used an eight-day daily diary from the Midlife in the United States (MIDUS) Refresher dataset for 782 participants (ages 25-75). Multilevel modeling results revealed that age moderated the relationship between daily time spent on social media and negative affect: for younger adults, on days when they spent more time on social media, they had more negative affect. For older adults, on days when they spent more time on social media, they had less negative affect. Surprisingly, daily time spent on social media was not related to daily positive affect, nor did this relationship differ by age. Implications for future research are discussed with a focus on how social media usage can contribute to daily well-being for adults of different ages.

Prior research links adaptive humor styles (affiliative and self-enhancing) with enhanced psychological well-being and maladaptive humor styles (aggressive and self-defeating) with worse psychological well-being, primarily through humor styles’ influence on individuals’ social interactions and efforts to positively reframe stressors. The present study examined the unique relation of each humor style with psychological well-being with a focus on understanding mechanisms of adjustment under highly stressful conditions. Ninety-nine parents of children with disabilities were surveyed at the beginning of the COVID-19 pandemic in the United States in March 2020, and 79 parents completed follow-up surveys in July 2020. As predicted, at T1, self-enhancing humor was associated with less psychological distress and greater family satisfaction, self-defeating humor was associated with greater distress, and aggressive humor was associated with lower family satisfaction. Moreover, affiliative humor predicted decreased psychological distress over time, whereas self-defeating humor predicted increased psychological distress and decreased family satisfaction over time. Relations were largely mediated by caregiver positive reappraisal, family efforts to reframe daily disability-related challenges, and negative social interactions. Future research should further examine the influence of caregiver humor styles on family dynamics, family reframing norms, and caregiving efficacy.

Objective: To investigate disparities in life satisfaction among older Hispanic immigrants in the United States relative to their native-born Hispanic and non-Hispanic White counterparts, and to identify factors associated with such disparities. Method: Cross-sectional data from 9,798 individuals age 60 and above from the Health and Retirement Study (HRS) were used to estimate ordinary least squares (OLS) regression models. Results: Hispanic immigrants reported the highest levels of life satisfaction of all groups. Wealthier older adults, who were socially engaged, had social support, and experienced fewer functional limitations and lower exposure to discrimination, were more satisfied with their lives in the overall sample. Interaction effects revealed that although education was associated with greater life satisfaction only among non-Hispanic Whites, co-residing with children was associated with greater life satisfaction only among Hispanics. Discussion: Although older Hispanic immigrants had the least amount of socioeconomic resources of all groups in our study, they were the most satisfied with their lives. Possible explanations and directions for future research are discussed.

A substantial portion of the older adult population suffers from frequent feelings of loneliness, but a large proportion remains relatively unscathed by loneliness. To date, research examining both protective and risk factors for loneliness has not included data from the United States. The present study used the first two waves of data from the National Social Life, Health, and Aging Project to examine sociodemographic, structural, and functional factors thought to be associated with loneliness in older adults. Functional limitations and low family support were associated with an increase in loneliness frequency (as were more strained friendships) and with transitioning from nonlonely to lonely status. Better self-rated health, higher levels of socializing frequency, and lower family strain were associated with transitioning from lonely to nonlonely status. Interventions that target these factors may be effective in preventing and reducing loneliness and its effects on health and well-being in older adults.

Understanding the relative public health impact of major microbiological hazards across the food supply is critical for a risk-based national food safety system. This study was conducted to estimate the U.S. health burden of 14 major pathogens in 12 broad categories of food and to then rank the resulting 168 pathogen-food combinations. These pathogens examined were Campylobacter, Clostridium perfringens, Escherichia coli O157:H7, Listeria monocytogenes, norovirus, Salmonella enterica, Toxoplasma gondii, and all other FoodNet pathogens. The health burden associated with each pathogen was measured using new estimates of the cost of illness and loss of quality-adjusted life years (QALYs) from acute and chronic illness and mortality. A new method for attributing illness to foods was developed that relies on both outbreak data and expert elicitation. This method assumes that empirical data are generally preferable to expert judgment; thus, outbreak data were used for attribution except where evidence suggests that these data are considered not representative of food attribution. Based on evaluation of outbreak data, expert elicitation, and published scientific literature, outbreak-based attribution estimates for Campylobacter, Toxoplasma, Cryptosporidium, and Yersinia were determined not representative; therefore, expert-based attribution were included for these four pathogens. Sensitivity analyses were conducted to assess the effect of attribution data assumptions on rankings. Disease burden was concentrated among a relatively small number of pathogen-food combinations. The top 10 pairs were responsible for losses of over $8 billion and 36,000 QALYs, or more than 50% of the total across all pairs. Across all 14 pathogens, poultry, pork, produce, and complex foods were responsible for nearly 60% of the total cost of illness and loss of QALYs.

Background: Living with life-limiting illness significantly impacts quality of life. A growing body of evidence suggests that arts engagement facilitated by artists promotes well-being. However, no synthesis of the literature exists to describe arts engagement delivered by artists with individuals receiving palliative care. Aim: To systematically review and synthesize evidence to identify outcomes and key knowledge gaps to inform future research and practice. Design: A systematic integrative literature review was conducted using a pre-defined search strategy and reported using PRISMA guidelines. Analysis was conducted iteratively and synthesis achieved using constant comparison to generate themes. Data sources: PubMed/MEDLINE, CINAHL, PsycINFO, Scopus, Web of Science, and Embase were searched for studies published between database inception and August 2020. Search terms included variations on arts/artists; patients/service users; and palliative or end-of-life care. Eligibility criteria was applied and study quality assessed. Results: Seven reviewed studies explored literary, performing, and visual arts engagement in hospitals, hospice and community settings in England, the United States, France, and Canada. Study designs, interventions and findings were discussed. Themes identified across studies associated arts engagement with (1) a sense of well-being, (2) a newly discovered, or re-framed, sense of self, (3) connection with others, and (4) challenges associated with practice. Conclusion: Recommendations for future research were offered in order to maximize benefits, minimize risks and address complexity of artists’ engagement in palliative care including: (1) consistency in methods and reporting; (2) inclusion of wider perspectives; and (3) key considerations for adapting the arts by health condition and art form.

Do acts of kindness improve the well-being of the actor? Recent advances in the behavioural sciences have provided a number of explanations of human social, cooperative and altruistic behaviour. These theories predict that people will be ‘happy to help’ family, friends, community members, spouses, and even strangers under some conditions. Here we conduct a systematic review and meta-analysis of the experimental evidence that kindness interventions (for example, performing ‘random acts of kindness’) boost subjective well-being. Our initial search of the literature identified 489 articles; of which 24 (27 studies) met the inclusion criteria (total N=4,045). These 27 studies, some of which included multiple control conditions and dependent measures, yielded 52 effect sizes. Multi-level modelling revealed that the overall effect of kindness on the well-being of the actor is small-to-medium (δ = 0.28). The effect was not moderated by sex, age, type of participant, intervention, control condition or outcome measure. There was no indication of publication bias. We discuss the limitations of the current literature, and recommend that future research test more specific theories of kindness: taking kindness-specific individual differences into account; distinguishing between the effects of kindness to specific categories of people; and considering a wider range of proximal and distal outcomes. Such research will advance our understanding of the causes and consequences of kindness, and help practitioners to maximise the effectiveness of kindness interventions to improve well-being.

Abstract Utilizing the first set of 5-year American Community Survey data available since the United States’ legalization of same-sex marriage in mid-2015, this poster investigates the economic security of older adults (age 50+) in same-sex marriages compared to those in same-sex partnerships who are cohabiting but not married. Viewed through the lens of cumulative disadvantage theory, we consider differences in the economic circumstances of same-sex couples by gender and by geographic location. Findings point to gender differences in economic well-being, but relatively few differences based on marital status. For example, rates of low income are somewhat higher among female couples than among their male counterparts, but marital status differences are not substantial. These findings suggest that the benefits of being married that have long been recognized among older adults may not extend equally to same-sex couples. Findings are discussed with respect to the emerging salience of marriage within the LGBTQ older community, future research opportunities, and important policy implications.

Attachment may have reached a turning point in which two sometimes incompatible approaches to individual differences in attachment are being compared. The outcome could influence future work in attachment. This article focuses on individual differences because applications of attachment are predicated on the consequences of individual differences for adaptation and well-being. The issue is which model is better suited to future research and clinical applications. Both models augment the original Ainsworth ABC model that everyone agrees is not sufficiently differentiated to cover the range of human behavior. The two models are “ABC+D” (the model that has disorganization (D) as its fourth category) and “DMM” (the model that expands the A and C categories from two subcategories each to a total of eight each, plus A/C combinations). The current disagreement has two sources: (a) the increasing acceptance outside the United States of the DMM, particularly in clinical and forensic settings, while the US remains largely unaware of the DMM; and (b) the recent announcement by prominent ABC+D researchers from Europe and the US that D is not a suitable category for clinical or forensic use. ABC+D researchers have not proposed an alternative, and some US funding sources and courts eschew attachment altogether, believing the theory itself lacks validity and utility, thus weakening attachment’s potential to inform clinical research and decision-making. This article proposes DMM as a viable alternative to both ABC+D and psychiatric diagnoses and examines the development and contributions of each model for the purpose of creating a model of individual differences in attachment that is scientifically robust, open to change as new evidence becomes available, and applicable to troubled individuals and families. Notably, attachment theory has engendered controversy from its beginnings. When John Bowlby offered attachment as a universal human characteristic that promoted species and individual survival, he was criticized by others in his field. When Mary Ainsworth identified the ABC categories of individual differences in attachment, her ideas were attacked from outside attachment theory. While the “first generation” issue around the existence of attachment has largely died away, a second generation of attachment theorists is disputing the nature of individual differences, their focus on individuals (ABC+D) or interpersonal systems (DMM Family Functional Formulations), and their relevance to clinical work. The ABC+D and DMM models that expand Ainsworth’s work were developed by two of her students, Mary Main (ABC+D) and Patricia Crittenden (DMM). They and their colleagues have worked separately for half a century producing two large and sometimes discrepant bodies of work, which have now become the topic of open debate. This bibliography focuses on the conceptual and empirical bases for that exchange. Part I outlines the roots of the ABC+D and DMM models, together with comparative validating information. Part II presents the central research findings on individual differences in attachment from four decades of research with each model. The authors wish to thank Robbie Duschinsky, Udita Iyengar, and Andrea Landini for their helpful comments on this bibliography.

Little is known about the overall experiences and feelings of diverse older populations during the 2020 COVID-19 pandemic. To provide the baseline information for future research and policy, this study analyzed the 2020 Health and Retirement Study COVID-19 project data ( n = 1782). More than 70% of older adults reported the following activities: watching TV (98%), reading (90%), using a computer and the internet (83%), gardening (82%), walking (75%), baking and cooking (73%), and praying (73%). Volunteering and attending community groups, which are known to benefit well-being, were unpopular (less than 8%). During the pandemic, older adults were generally satisfied with their lives, but more than half of them were concerned about their own health, family’s health, and future prospects. Our study also showed the differences in the experiences and feelings by gender and race as well as the intersection of gender and race in the United States.
