RESUMO
Although stress and adversity are largely universal experiences, people exposed to greater hardship are at increased risk for negative health consequences. Recent studies identify accelerated biological aging as a mechanism that could explain how trauma and adversity gives rise to poor health, and advances in this area of study coincide with technological innovations in the measurement of biological aging, particularly epigenetic profiles consistent with accelerated aging derived from DNA methylation. In this review, we provide an overview of the current literature examining how adversity might accelerate biological aging, with a specific focus on social and health behaviors. The most extensive evidence in this area suggests that health-compromising behaviors, particularly smoking, may partially explain the association between adversity and accelerated aging. Although there is relatively less published support for the role of social behaviors, emerging evidence points to the importance of social connection as a mechanism for future study. Our review highlights the need to determine the extent to which the associations from adversity to accelerated aging are consistent with causal processes. As we consider these questions, the review emphasizes methodological approaches from the causal inference literature that can help deepen our understanding of how stress and trauma might result in poor health. The use of these methodologies will help provide evidence as to which behavioral interventions might slow aging and improve health, particularly among populations that more often experience adversity and trauma.

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.
RESUMO
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.

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.
RESUMO
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.

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.

Attachment insecurity is a transdiagnostic marker of risk associated with interpersonal emotion dysregulation and adverse psychosocial outcomes across the lifespan. Few interventions target the enhancement of attachment security in late adolescence. Most programs focus on strengthening the adolescent-caregiver relationship; meanwhile, youth increasingly spend less time with their families and look to peer relationships as a source of connection, particularly as they transition to college. Drawing from the principles of Emotionally Focused Therapy, we developed a psychotherapeutic peer mentorship program to enhance attachment security for insecurely attached youth during the transition to college. We tested the preliminary efficacy of Emotionally Focused Mentorship (EFM) in an open pilot trial by pairing (N = 82) insecurely attached first-year college students (i.e., "mentees") with securely attached mentors. Across five weekly sessions, mentors helped mentees identify and express their emotions in close relationships by working through different relational scenarios. Attachment and mental health trajectories were self-reported three times over five weeks and analyzed using Bayesian growth curve models. Across five weeks, participants reported improvements in attachment anxiety and avoidance, emotion regulation difficulties, depressive symptoms, loneliness, and self-esteem. Participants who completed the intervention (n = 55) noted improvements in their psychological wellbeing and interpersonal relationships. Results are promising and highlight the need to conduct a randomized clinical trial to test if these effects are causal. Given rising mental health demands, trained peer mentors may be a cost-effective way to improve attachment and psychological outcomes for insecurely attached participants during the transition to college.
RESUMO
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.

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).

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.

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.

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.
RESUMO
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.

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.

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).

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.
RESUMO
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.

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.

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.
RESUMO
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.
