Loneliness and social isolation are not associated with executive functioning in a cross-sectional study of cognitively healthy older adults.

The literature on the relationship between social interaction and executive functions (EF) in older age is mixed, perhaps stemming from differences in EF measures and the conceptualization/measurement of social interaction. We investigated the relationship between social interaction and EF in 102 cognitively unimpaired older adults (ages 65-90). Participants received an EF battery to measure working memory, inhibition, shifting, and global EF. We measured loneliness subjectively through survey and social isolation objectively through naturalistic observation. Loneliness was not significantly related to any EF measure (p-values = .13-.65), nor was social isolation (p-values = .11-.69). Bayes factors indicated moderate to extremely strong evidence (BF01 = 8.70 to BF01 = 119.49) in support of no relationship.. Overall, these findings suggest that, among cognitively healthy older adults, there may not be a robust cross-sectional relationship between EF and subjective loneliness or objective social isolation.

Loneliness and depression: bidirectional mendelian randomization analyses using data from three large genome-wide association studies.

Major depression (MD) is a serious psychiatric illness afflicting nearly 5% of the world's population. A large correlational literature suggests that loneliness is a prospective risk factor for MD; correlational assocations of this nature may be confounded for a variety of reasons. This report uses Mendelian Randomization (MR) to examine potentially causal associations between loneliness and MD. We report on analyses using summary statistics from three large genome wide association studies (GWAS). MR analyses were conducted using three independent sources of GWAS summary statistics. In the first set of analyses, we used available summary statistics from an extant GWAS of loneliness to predict MD risk. We used two sources of outcome data: the Psychiatric Genomics Consortium (PGC) meta-analysis of MD (PGC-MD; N = 142,646) and the Million Veteran Program (MVP-MD; N = 250,215). Finally, we reversed analyses using data from the MVP and PGC samples to identify risk variants for MD and used loneliness outcome data from UK Biobank. We find robust evidence for a bidirectional causal relationship between loneliness and MD, including between loneliness, depression cases status, and a continuous measure of depressive symptoms. The estimates remained significant across several sensitivity analyses, including models that account for horizontal pleiotropy. This paper provides the first genetically-informed evidence that reducing loneliness may play a causal role in decreasing risk for depressive illness, and these findings support efforts to reduce loneliness in order to prevent or ameliorate MD. Discussion focuses on the public health significance of these findings, especially in light of the SARS-CoV-2 pandemic.

Sleep Efficiency and Naturalistically-Observed Social Behavior Following Marital Separation: The Critical Role of Contact with an Ex-partner.

Marital disruption is associated with increased risk for a range of poor health outcomes, including disturbed sleep. This report examines trajectories of actigraphy-assessed sleep efficiency following marital separation as well as the extent to which daily social behaviors and individual differences in attachment explain variability in these trajectories over time. One hundred twenty-two recently-separated adults (N = 122) were followed longitudinally for three assessment periods over five months. To objectively assess daily social behaviors and sleep efficiency, participants wore the Electronically Activated Recorder (EAR) during the day (for one weekend at each assessment period) and an actiwatch at night (for seven days at each assessment period). Greater time spent with an ex-partner, as assessed by the EAR, was associated with decreased sleep efficiency between participants (p = .003). Higher attachment anxiety was also associated with decreased sleep efficiency (p = .03), as was the EAR-observed measure of "television on." The latter effect operated both between (p = .004) and within participants (p = .005). Finally, study timepoint moderated the association between EAR-observed measure of "television on" and sleep efficiency (p = .007). The current findings deepen our understanding of sleep disturbances following marital separation and point to contact with an ex-partner and time spent with the television on as behavioral markers of risk.

The paucity of morality in everyday talk.

Given its centrality in scholarly and popular discourse, morality should be expected to figure prominently in everyday talk. We test this expectation by examining the frequency of moral content in three contexts, using three methods: (a) Participants' subjective frequency estimates (N = 581); (b) Human content analysis of unobtrusively recorded in-person interactions (N = 542 participants; n = 50,961 observations); and (c) Computational content analysis of Facebook posts (N = 3822 participants; n = 111,886 observations). In their self-reports, participants estimated that 21.5% of their interactions touched on morality (Study 1), but objectively, only 4.7% of recorded conversational samples (Study 2) and 2.2% of Facebook posts (Study 3) contained moral content. Collectively, these findings suggest that morality may be far less prominent in everyday life than scholarly and popular discourse, and laypeople, presume.

Spinning Your Wheels: Psychological Overinvolvement and Actigraphy-Assessed Sleep Efficiency Following Marital Separation.

BACKGROUND: This study investigated the ways in which adults reflect on their psychological experiences amid a recent marital separation and how these patterns of thought, manifest in language, are associated with self-reported negative affect and actigraphy-assessed sleep disturbance. METHODS: In a sample of 138 recently separated adults assessed three times over five months, we examined within- and between-person associations among psychological overinvolvement (operationalized using verbal immediacy derived as a function of the language participants used to discuss their relationship history and divorce experience), continued attachment to an ex-partner, negative affect, and sleep efficiency. RESULTS: The association between psychological overinvolvement and negative affect operated at the within-person level, whereas the associations between psychological overinvolvement and sleep disturbance, as well as negative affect and sleep disturbance, operated at the between-person level. CONCLUSIONS: These findings shed light on the intraindividual processes that may explain why some people are more susceptible to poor outcomes after separation/divorce than others. Our findings suggest that individuals who express their divorce-related thoughts and feelings in a psychologically overinvolved manner may be at greatest risk for sleep disturbances after marital separation/divorce.

Cardiovascular reactivity, stress, and personal emotional salience: Choose your tasks carefully.

Both greater cardiovascular reactivity and lesser reactivity ("blunting") to laboratory stressors are linked to poor health outcomes, including among people who have a history of traumatic experiences. In a sample of recently separated and divorced adults (N = 96), this study examined whether differences in cardiovascular reactivity might be explained by differences in the personal emotional salience of the tasks and trauma history. Participants were assessed for trauma history, current distress related to their marital dissolution, and cardiovascular reactivity during two tasks, a serial subtraction math stressor task and a divorce-recall task. Participants with a greater trauma history evidenced less blood pressure reactivity to the serial subtraction task (a low personal emotional salience task) when compared to participants with less trauma history. In contrast, participants with a greater trauma history evidenced higher blood pressure reactivity to the divorce-recall task, but only if they also reported more divorce-related distress (high personal emotional salience). These associations were not significant for heart rate reactivity. Among people with a history of more traumatic experiences, a task with low personal salience was associated with a lower blood pressure response, whereas a task with higher personal emotional salience was associated with a higher blood pressure response. Future studies examining cardiovascular reactivity would benefit from determining the personal emotional salience of tasks, particularly for groups that have experienced stressful life events or trauma.

Hispanic Ethnic Density May Be Protective for Older Black/African American and Non-Hispanic White Populations for Some Health Conditions: An Exploration of Support and Neighborhood Mechanisms.

BACKGROUND AND PURPOSE: Hispanic ethnic density (HED) is associated with salubrious health outcomes for Hispanics, yet recent research suggests it may also be protective for other groups. The purpose of this study was to test whether HED was protective for other racial-ethnic groups. We tested whether social support or neighborhood social integration mediated the association between high HED and depressive symptoms (CES-D) and physical morbidity 5 years later. Lastly, we tested whether race-ethnicity moderated both main and indirect effects. METHODS: We used Waves 1 (2005-2006), and 2 (2010-2011) from The National Social Life, Health, and Aging Project, a national study of older U.S. adults. Our sample was restricted to Wave 1 adults who returned at Wave 2, did not move from their residence between waves, and self-identified as Hispanic, non-Hispanic White (NHW), or non-Hispanic Black (NHB; n = 1,635). We geo-coded respondents' addresses to a census-tract and overlaid racial-ethnic population data. Moderated-mediation models using multiple imputation (to handle missingness) and bootstrapping were used to estimate indirect effects for all racial-ethnic categories. RESULTS: Depressive symptoms were lower amongst racial-ethnic minorities in ethnically (Hispanic) dense neighborhoods; this effect was not stronger in Hispanics. HED was not associated with physical morbidity. Sensitivity analyses revealed that HED was protective for cardiovascular events in all racial-ethnic groups, but not arthritis, or respiratory disease. Social support and neighborhood social integration were not mediators for the association between HED and outcomes, nor were indirect effects moderated by race-ethnicity. CONCLUSIONS: This study offers some evidence that HED may be protective for some conditions in older adults; however, the phenomena underlying these effects remains a question for future work.

Relationship dissolution and psychopathology.

Studies using probability samples have yielded cross-sectional and longitudinal associations between relationship dissolution and psychopathology, including depressive, anxiety, and substance use symptoms and disorders. The present review summarizes theory relevant to the association of relationship dissolution to psychopathology, discusses the time course over which postdissolution psychopathology may be most likely to manifest, and selectively reviews empirical findings regarding main and moderated associations between relationship dissolution and psychopathology. We conclude by acknowledging the need for continued study of the association between relationship dissolution and psychopathology, including research that rules out potential rival explanations (i.e., confounding variables) for this association and examines this association across cultures and types of intimate relationships (e.g., cohabiting relationships).

Social baseline theory: State of the science and new directions.

Social baseline theory (SBT) maintains that the primary human ecology is a social ecology. Because of this fact, the theory predicts that humans will find it easier and less energetically taxing to regulate emotion and act when in proximity to familiar and predictable others. This article reviews new empirical and theoretical work related to SBT and highlights areas of needed research. Among these exciting developments are investigations of the neural mechanisms of social emotion regulation, the creation of a model of social allostasis, and work investigating at the impact of social proximity in real-world contexts. SBT continues to accrue support and inspire new theoretical and empirical contributions.

Divorce, health, and socioeconomic status: An agenda for psychological science.

This brief review article discusses marital dissolution and health with a focus on two specific themes. First, we introduce and discuss the search for plausible causal pathways that link the end of marriage to distal health outcomes. Second, we suggest that the socioeconomic status disruptions that follow divorce represent a plausible causal pathway and emphasize the need for more psychological science in this area of study. Although there is substantial literature that demonstrates that divorced adults, especially divorced women, experience significant financial disruptions, the research in this area remains broad and largely the province of family sociology and demography. Research is needed to better understand adults' psychological and behavioral responses to changes in their financial situation after the end of marriage.

Good Theories in Need of Better Data: Combining Clinical and Social Psychological Approaches to Study the Mechanisms Linking Relationships and Health.

The study of intimate relationships and health is a fast-growing discipline with numerous well-developed theories, many of which outline specific interpersonal behaviors and psychological pathways that may give rise to good or poor health. In this article, we argue that the study of relationships and health can move toward interrogating these mechanisms with greater precision and detail, but doing so will require a shift in the nature of commonly used research methods in this area. Accordingly, we draw heavily on the science of behavior change and discuss six key methodologies that may galvanize the mechanistic study of relationships and health: dismantling studies, factorial studies, experimental therapeutics, experimental mediation research, multiple assessments, and recursive modeling. We provide empirical examples for each strategy and outline new ways in which a given approach may be used to study the mechanisms linking intimate relationships and health. We conclude by discussing the key challenges and limitations for using these research strategies as well as novel ideas about how to integrate this work into existing paradigms within the field.

Genetically informative analysis of the association between intimate relationship adjustment and health.

OBJECTIVE: Prior research has found a positive association between the quality or adjustment of an individual's intimate relationship, such as marriage, and their physical health. However, it is possible that this association may be due, at least in part, to confounding variables (i.e., variables that are causally associated both with relationship adjustment and health and could account for their covariation), including genetically influenced confounds. This study was conducted using a genetically informative sample of twins to examine the association between intimate relationship adjustment and self-rated health, accounting for unmeasured genetic and environmental confounds. METHOD: A Swedish sample of 539 monozygotic and dizygotic twins (321 male twin pairs and 218 female twin pairs) and their spouse or long-term partner completed self-report measures of relationship adjustment and health. RESULTS: Relationship adjustment was positively associated with self-rated health in male and female twins. For male twins, nonshared environmental influences largely accounted for the association between relationship adjustment and health; for female twins, this association was generally explained by shared and nonshared environmental influences. For male twins, results obtained from partners' reports of relationship adjustment were largely consistent with those obtained from twins' reports. CONCLUSIONS: Results suggest that the association between relationship adjustment and self-rated health remains after accounting for shared genetic influences, and that nonshared environmental influences, such as partners' characteristics, account for the association between relationship adjustment and self-rated health in men.

Use of a Guided Imagery Mobile App (See Me Serene) to Reduce COVID-19-Related Stress: Pilot Feasibility Study.

BACKGROUND: The SARS-CoV-2 pandemic has led to concerns about mental health resulting from regional and national lockdowns, social isolation, job loss, and concern about disease exposure. OBJECTIVE: We describe results of the pilot feasibility study of the See Me Serene mHealth app. The app provides users with immersive, vivid, nature experiences to reduce stress and anxiety related to COVID-19 and other isolation. The goals of the study were to develop the See Me Serene app and test the feasibility and acceptability of study procedures, and explore the potential impact of the app on stress and anxiety. METHODS: We developed and tested the See Me Serene app and our study procedures for feasibility, and gathered preliminary data with a goal of 100 participants. The research was conducted in 2 phases: (1) development and internal testing of the app; and (2) feasibility and pilot testing with participants recruited online through earned media (eg, news stories), presentations at a university campus, and social media (eg, online sharing of earned media and presentations). The feasibility study employed a mixed methods, within-subjects, pre-/posttest design. At baseline and 30-day follow-up, we assessed stress-related variables via validated self-report measures and saliva samples for determination of cortisol concentrations. RESULTS: We met or surpassed all our feasibility benchmarks for recruitment (101 participants recruited), retention (91% [90/99] of 30-day assessment completed), and data collection (99 participants completed all baseline data; 85% [84/99] of salivary cortisol samples returned). Participants adhered to the intervention. On average, participants listened to 48.2 audio files over 30 days or approximately 1.6 audio files per day. Participants were satisfied with the app, with 87% (78/90) rating the app as helpful in dealing with stress and anxiety. The app showed the potential to reduce stress, anxiety, loneliness, and worry. We did not find significant differences (P=.41) in cortisol levels over time. Our findings suggest that future research is warranted to test the efficacy of the See Me Serene app with a representative, diverse sample. CONCLUSIONS: There is a need for evidence-based and easily disseminable stress-reduction interventions. See Me Serene is a feasible intervention and has the potential to reduce stress related to COVID-19 and other forms of social isolation. More research on See Me Serene is warranted.

A controlled trial of two mind-body interventions for grief in widows and widowers.

Objective: Following bereavement, yearning and grief rumination are repetitive cognitive processes that can lead to disordered grief. Mindfulness training (MT) has been shown to reduce maladaptive repetitive thought. The current quasi-randomized controlled trial examined the feasibility, acceptability, and preliminary efficacy of MT for bereavement-related grief. Method: Ninety-five widow(er)s (Mage = 67.5, 79% women, 98% White) between 6 months to 4 years post-loss were assigned to a 6-week MT intervention or a progressive muscle relaxation (PMR) intervention, or a wait-list condition. Outcome measures were grief severity (Revised Inventory of Complicated Grief), yearning (Yearning in Situations of Loss), rumination (Utrecht Grief Rumination Scale), and decentering (Experiences Questionnaire-Decentering) assessed at baseline, Weeks 2 and 4 of intervention, post-intervention, and 1-month post-intervention. Growth curve analysis examined group differences in rates of improvement in outcomes through follow-up and associations with improvement in grief severity. Results: The MT and PMR groups showed significant rates of decline in grief severity and yearning, though only the PMR group showed a greater rate of decline in grief severity than wait-list. All groups showed significant rates of decline in grief rumination. The PMR and wait-list groups showed significant rates of increase in decentering compared to the MT group. Conclusions: Results support the feasibility and acceptability of MT and PMR for widow(er)s as well as the preliminary efficacy of PMR for improving grief severity in widow(er)s compared to a wait-list control condition. With replication, PMR could be a standalone intervention for non-disordered grief or a component of treatment for disordered grief. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Intimate Relationships and Depression: Searching for Causation in the Sea of Association.

This article provides a critical review of existing research on intimate (marriage or marriage-like) relationship distress and risk for depression. Using the meta-framework of research triangulation, we seek to synthesize research evidence across several different methodologies and study designs and to draw the most reliable conclusion regarding a potential causal association between relationship distress and depression. Focusing on existing correlational (i.e., observational), genetically informed, and intervention (i.e., experimental) research on the association between relationship distress and depression, we conclude that the existing body of research evidence supports the claim that relationship distress is a causal risk factor for depression. A secondary aim of the article is to highlight a variety of effective methods that, when viewed from the perspective of triangulation, enhance the pursuit of causal inference, including propensity score matching, target trial emulation, directed acyclic graph approach, and Mendelian randomization.

Deep multiple instance learning for foreground speech localization in ambient audio from wearable devices.

Over the recent years, machine learning techniques have been employed to produce state-of-the-art results in several audio related tasks. The success of these approaches has been largely due to access to large amounts of open-source datasets and enhancement of computational resources. However, a shortcoming of these methods is that they often fail to generalize well to tasks from real life scenarios, due to domain mismatch. One such task is foreground speech detection from wearable audio devices. Several interfering factors such as dynamically varying environmental conditions, including background speakers, TV, or radio audio, render foreground speech detection to be a challenging task. Moreover, obtaining precise moment-to-moment annotations of audio streams for analysis and model training is also time-consuming and costly. In this work, we use multiple instance learning (MIL) to facilitate development of such models using annotations available at a lower time-resolution (coarsely labeled). We show how MIL can be applied to localize foreground speech in coarsely labeled audio and show both bag-level and instance-level results. We also study different pooling methods and how they can be adapted to densely distributed events as observed in our application. Finally, we show improvements using speech activity detection embeddings as features for foreground detection.

Does the Hispanic Mortality Advantage Vary by Marital Status Among Postmenopausal Women in the Women's Health Initiative?

BACKGROUND: Literature assessing the effect of marital status on mortality has underrepresented, or altogether omitted Hispanics and the potential moderating effect of Hispanic ethnicity on these relationships. Given cultural and network dynamics, marital advantages in older Hispanic women may be greater than other groups given their family-focused, collectivist orientation. PURPOSE: The purpose of this study was to understand whether older Hispanic women exhibited a more pronounced marital advantage as compared with non-Hispanic Whites. METHODS: We used longitudinal data from the Women's Health Initiative (WHI) Observational Study and Clinical Trials (N = 161,808) collected initially from 1993 to 1998 and followed until 2018. Our sample excluded those respondents indicating "other" as their race-ethnicity and those missing marital status and race-ethnicity variables (N = 158,814). We used Cox-proportional hazards models to assess the association between race-ethnicity, marital status, and the interactive effect of race-ethnicity and marital status on survival. RESULTS: After controlling for socioeconomic status (SES) and health controls, we found a Hispanic survival advantage when compared with non-Hispanic Whites and all other racial-ethnic groups with the exception of Asian/Pacific Islander women (all significant HRs < 0.78, all ps ≤ 0.001). Hispanics had a higher rate of divorce when compared with non-Hispanic Whites. The interactive effect of race-ethnicity and marital status was not significant. CONCLUSIONS: U.S. Hispanic, postmenopausal women exhibit a mortality advantage over and above marital status despite their high rates of divorce. Implications and potential explanations are discussed. CLINICAL TRIAL REGISTRATION: NCT00000611.

Contact with an Ex-partner is Associated with Psychological Distress after Marital Separation.

This study examined the association between naturalistically-observed in-person contact with one's ex-partner and separation-related psychological distress (SRPD). 122 recently-separated adults were assessed using the Electronically Activated Recorder (Mehl, 2017) on three occasions across five months. The association between in-person contact with one's ex-partner, as a between-person variable, and concurrent SRPD was not reliably different from zero, nor was the time-varying effect of in-person contact. However, more frequent in-person contact with one's ex-partner predicted higher SRPD two months later, above and beyond the variance accounted for by concurrent in-person contact, demographic, relationship, and attachment factors. Follow-up analyses yielded that this effect was only present for people without children; a one standard deviation increase in in-person contact offset and slowed the predicted decline in SRPD over two months by 112%. Our discussion emphasizes new ways to think about the role of in-person contact in shaping adults' psychological adjustment to separation over time.

Social Distancing as a Health Behavior: County-Level Movement in the United States During the COVID-19 Pandemic Is Associated with Conventional Health Behaviors.

BACKGROUND: Social distancing-when people limit close contact with others outside their household-is a primary intervention available to combat the COVID-19 pandemic. The importance of social distancing is unlikely to change until effective treatments or vaccines become widely available. However, relatively little is known about how best to promote social distancing. Applying knowledge from social and behavioral research on conventional health behaviors (e.g., smoking, physical activity) to support public health efforts and research on social distancing is promising, but empirical evidence supporting this approach is needed. PURPOSE: We examined whether one type of social distancing behavior-reduced movement outside the home-was associated with conventional health behaviors. METHOD: We examined the association between GPS-derived movement behavior in 2,858 counties in USA from March 1 to April 7, 2020 and the prevalence of county-level indicators influenced by residents' conventional health behaviors. RESULTS: Changes in movement were associated with conventional health behaviors, and the magnitude of these associations were similar to the associations among the conventional health behaviors. Counties with healthier behaviors-particularly less obesity and greater physical activity-evidenced greater reduction in movement outside the home during the initial phases of the pandemic in the USA. CONCLUSIONS: Social distancing, in the form of reduced movement outside the home, is associated with conventional health behaviors. Existing scientific literature on health behavior and health behavior change can be more confidently used to promote social distancing behaviors during the COVID-19 pandemic.

Marital Status, Close Relationships, and All-Cause Mortality: Results From a 10-Year Study of Nationally Representative Older Adults.

OBJECTIVE: Becoming widowed is associated with an increased risk of early mortality. Drawing on theoretical literature related to social support and health, the present study evaluated whether the quantity of close relationships might differentially moderate the relationship between marital status (widowed versus married) and mortality risk 10 years later. METHOD: Data were obtained from the National Social Life Health and Aging Project. A diverse group of older adults (n = 2347) were interviewed three times for 10 years. Information on close friends/family, marital status, and mortality was gathered. Logistic regression and moderation analyses were used to test whether the quantity of close relationships conditioned the risk of death for married and widowed adults 10 years later. RESULTS: The quantity of close relationships moderated the association between marital status and mortality risk (B = -0.35, SE = 0.11, p = .002). Compared with their married counterparts, widowed older adults who had fewer than four to six close relationships had an increased risk of death 10 years later (B = -0.35, SE = 0.09, p < .001); similarly, among people who reported few close relationships, widowed adults had an increased risk of death compared with their married counterparts (B = 0.54, SE = 0.15, p < .001). These findings remained significant after accounting for demographics, health behaviors/chronic health conditions, and psychological distress. This effect is comparable to the increased mortality risk associated with smoking cigarettes. CONCLUSIONS: Having fewer than four to six close relationships is associated with an increased mortality risk for widowed older adults.
