Bidirectional Associations Between Loneliness, Emotional Support, and Sleep in Daily Life
OBJECTIVE: Evidence suggests a link between positive social relationship perceptions and improved sleep (e.g., quality, efficiency) across the life span. Less work has probed the directionality of these relationships. Here, we report findings from the first study to examine bidirectional between- and within-person associations between loneliness and emotional support with daily life measures of sleep. METHODS: Participants were 389 healthy adults…
Longitudinal associations of social support, everyday social interactions, and mental health during the Covid-19 pandemic
Main effect models contend that perceived social support benefits mental health in the presence and the absence of stressful events, whereas stress-buffering models contend that perceived social support benefits mental health especially when individuals are facing stressful events. We tested these models of how perceived social support impacts mental health during the COVID-19 pandemic and evaluated whether characteristics of everyday social inte…
A Longitudinal Study of Age-Based Change in Blood Pressure Reactivity and Negative Affect Reactivity to Natural Stressors
OBJECTIVE: Aging is theoretically accompanied by emotional gains, but physiological self-regulatory losses. Emotional and physiological regulation can be operationalized as the extent of an increase in negative affect and blood pressure upon experiencing a stressor (i.e., reactivity). The direction of age-based changes in negative affect reactivity to stressors is uncertain. In addition, evidence for age-based increases in blood pressure reactivi…
Sleep and Daily Social Experiences as Potential Mechanisms Linking Social Integration to Nocturnal Blood Pressure Dipping
This was the first study to investigate sleep and social mechanisms underlying the link between social integration and nocturnal BP dipping. Because sleep regularity is modifiable, this pathway represents a potential intervention target to promote nocturnal BP dipping
What Can We Learn From More Than 140,000 Moments of Ecological Momentary Assessment–Assessed Negative Emotion and Ambulatory Blood Pressure? A Systematic Review and Meta-Analysis
Daily stress reactivity
BACKGROUND: The processes through which social support exerts its influence in daily life are not well understood. Arguably, its salutary effects as an environmental variable might be construed as shared effects of personality. METHOD: To test this possibility, we investigated the unique and shared effects of personality and social support on daily stressor exposure (social conflict, task strain) and on the within-person association of stressor e…
Social Integration and Diurnal Cortisol Decline
OBJECTIVE: A growing number of studies have associated various measures of social integration, the diversity of social roles in which one participates, with alterations in hypothalamic-pituitary-adrenocortical (HPA) functioning. The pathways through which social integration may be linked to HPA functioning, however, are as yet unknown. The present study examined whether daily social interactions, affective responses, health behaviors, and persona…
The double burden of racial discrimination in daily-life moments
Objective: Racial discrimination is a common experience for African Americans, but no research has examined how discrimination reported in daily-life moments influences concurrent negative emotions and psychosocial resources. Method: Emerging adult African Americans ( N = 54) reported hourly on momentary racial discrimination, negative emotions, and psychosocial resources across two days. Results: Controlling for past discrimination and trait emo…
Ambulatory Blood Pressure Reactivity as a Moderator in the Association Between Daily Life Psychosocial Stress and Carotid Artery Atherosclerosis
OBJECTIVE: We examined whether associations between daily psychosocial stressor exposures and carotid artery intima-medial thickness (IMT) may be stronger among those showing larger stress-related cardiovascular reactivity (CVR) during the course of daily living. METHODS: A total of 474 healthy working adults (ages 30-54 years) collected ambulatory blood pressure and recorded their daily experiences, using electronic diaries, during two 2-day per…
Omega-3 Supplementation and the Neural Correlates of Negative Affect and Impulsivity
OBJECTIVE: In clinical trials, omega-3 fatty acid supplementation improves symptoms in psychiatric disorders involving dysregulated mood and impulse control, yet it is unclear whether in healthy adults, omega-3 fatty acid supplementation affects mood, impulse control, and the brain systems supporting these processes. Accordingly, this study tested the hypotheses that eciosapentaenoic (EPA) and docosahexaenoic (DHA) acid supplementation reduces ne…
Early Life Family Conflict, Social Interactions, and Carotid Artery Intima-Media Thickness in Adulthood
OBJECTIVE: Conflict in early life family environments is known to affect psychosocial functioning and coping styles into adulthood and is reported to negatively affect access to psychosocial resources that are critical to the management of stress. However, it remains unknown whether early life family conflict similarly affects subclinical cardiovascular disease (CVD) in adulthood. We predicted that family conflict in early life would be associate…
Childhood Socioeconomic Status and the Occurrence of Recent Negative Life Events as Predictors of Circulating and Stimulated Levels of Interleukin-6
OBJECTIVES: Evidence supports an inverse association of childhood socioeconomic status (SES) with systemic inflammation in adulthood. However, it remains to be determined whether this association is dependent on exposure to stressful life experiences. METHODS: We predicted that the combination of a high number of recent negative life events and low childhood SES would be associated with the highest levels of both circulating interleukin (IL)-6 an…
The Role of Occupational Status in the Association Between Job Strain and Ambulatory Blood Pressure During Working and Nonworking Days
OBJECTIVES: The objectives of this study were to determine whether job strain is more strongly associated with higher ambulatory blood pressure (ABP) among blue-collar workers compared with white-collar workers, to examine whether this pattern generalizes across working and nonworking days and across sex, and to examine whether this pattern is accounted for by psychosocial factors or health behaviors during daily life. METHODS: A total of 480 hea…
Daily Marital Interaction Quality and Carotid Artery Intima-Medial Thickness in Healthy Middle-Aged Adults
OBJECTIVE: To examine the association between marital interaction quality during daily life and subclinical cardiovascular disease (CVD). Studies have shown that marital status and quality of marriage are associated with cardiovascular health. However, little is known about the role of marital interaction quality during daily life in contributing to these effects. METHODS: The sample consisted of 281 healthy, employed middle-aged adults who were …
Depressive Symptom Clusters as Predictors of 6-Year Increases in Insulin Resistance
OBJECTIVE: To examine longitudinal bidirectional associations between two depressive symptom clusters-the cognitive-affective and somatic-vegetative clusters--and insulin resistance, a marker of prediabetes. METHODS: Participants were 269 adults aged 50 to 70 years without diabetes enrolled in the Pittsburgh Healthy Heart Project, a prospective cohort study. At baseline and 6-year visits, participants completed the Beck Depression Inventory-II (B…
Daily Psychological Demands Are Associated With 6-Year Progression of Carotid Artery Atherosclerosis
OBJECTIVE: We examine associations between the perception of ongoing psychological demands by ecological momentary assessment (EMA) and 6-year changes in carotid artery atherosclerosis by ultrasonography. METHODS: A total of 270 initially healthy participants collected ambulatory blood pressure (ABP) and recorded their daily experiences, using electronic diaries, during two 3-day periods. Mean intima-media thickness (IMT) and plaque were assessed…
Depressive Symptoms Moderate the Influence of Hostility on Serum Interleukin-6 and C-Reactive Protein
Objective: Recent evidence suggests that depressive symptoms and hostility may act together, as interacting factors, to have an effect on the circulating levels of inflammatory markers relevant to coronary artery disease. Further research, however, is needed to clarify the nature of this interaction and to determine whether previous findings extend to older adults. In this report we examined the cross-sectional associations of depressive symptoms…
Influence of Race and Socioeconomic Status on Sleep
Objective: To examine the independent and interactive effects of race and socioeconomic status (SES) on objective indices and self-reports of sleep. Methods: The sleep of 187 adults (41% black; mean age = 59.5 ± 7.2 years) was examined. Nine nights of actigraphy and two nights of inhome polysomnography (PSG) were used to assess average sleep duration, continuity, and architecture; self-report was used to assess sleep quality. Psychosocial factors…
Frequency of Spousal Interaction and 3-Year Progression of Carotid Artery Intima Medial Thickness
Objective: We employed Ecological Momentary Assessment (EMA) real-time recording in the natural setting to determine whether spousal interaction frequency predicts 3-year progression of carotid artery intima medial thickening (IMT). Methods: Participants were 250 healthy, older adults (M age = 61, 48% female) who, at baseline, underwent 6 days of ambulatory monitoring using electronic diaries to collect data on mood, activity, and posture, as wel…
Psychosocial Stress and Cardiovascular Risk
We describe an ecological momentary assessment (EMA) protocol designed to measure daily life experiences along several psychosocial dimensions (Social Conflict, Task Demand, Decisional Control, Negative Affect, and Arousal) hypothesized to be relevant for cardiovascular disease risk. In a large community sample, these assessments have been administered in conjunction with ambulatory blood pressure (ABP) monitoring and measures of subclinical card…

Cardiovascular Reactivity and Development of Preclinical and Clinical Disease States
OBJECTIVE: The objective of this review is to evaluate the evidence for the hypothesis that cardiovascular reactivity can predict the development of preclinical (elevated blood pressure, ventricular remodeling, carotid atherosclerosis) and/or clinical cardiovascular disease states. METHODS: A review of the literature was conducted examining prospective studies. RESULTS: Three large epidemiological studies with long-term follow-up periods (20 year…
Cardiovascular Reactivity to Psychological Challenge
OBJECTIVE AND METHODS: This article is a selective review of recent findings bearing on the conceptualization and measurement of cardiovascular reactivity to psychological challenge, with a focus on several issues relevant to the reliability, content validity, construct validity, and criterion validity of these measures. RESULTS AND CONCLUSIONS: With respect to reliability, use of standardized task demands and aggregated scores are associated wit…
Covariation of Psychosocial Characteristics Associated With Cardiovascular Disease
OBJECTIVE: Three psychosocial characteristics associated with cardiovascular disease (CVD)-depression, hostility, and social support-tend to correlate with one another. However, the causes of each characteristic and why they tend to co-occur are not completely understood. Therefore, the current study used a twin design to examine the relative contributions of genetic and environmental influences to the variation and covariation of these three psy…
Partner Interactions Are Associated With Reduced Blood Pressure in the Natural Environment
OBJECTIVE: The objective of this study was to examine the effects of partner interactions on ambulatory blood pressure in a sample of 120 healthy adults who were monitored over a 6-day period. METHODS: After each blood pressure measurement, participants rated characteristics of ongoing social interactions, along with emotional activation, physical activity, talking, posture, and other covariates, with computer-assisted self-report assessments. RE…
A Global Measure of Perceived Stress
This paper presents evidence from three samples, two of college students and one of participants in a community smoking-cessation program, for the reliability and validity of a 14-item instrument, the Perceived Stress Scale (PSS), designed to measure the degree to which situations in one's life are appraised as stressful. The PSS showed adequate reliability and, as predicted, was correlated with life-event scores, depressive and physical symptoma…

Biobehavioral factors in sudden cardiac death
The authors examine the recent literature on psychological factors and sudden cardiac death and explore the mediating psychophysiological processes by which these variables may be associated. Direct evidence that psychosocial stressors and their correlates may be causally linked with sudden cardiac death in humans is not conclusive, but there is abundant convergent evidence that several physiological precursors of sudden death may be promoted by …

Social support reduces cardiovascular reactivity to psychological challenge
In this study we investigated the effects of nonevaluative social interaction on the cardiovascular response to psychological challenge. Thirty-nine college-age females appeared accompanied ("Friend" condition) or unaccompanied ("Alone" condition) to an experimental laboratory. In the Friend condition, partners were present while the subject participated in two laboratory tasks, and the partners' evaluation potential was minimized by design. Subj…

Affiliation Moderates the Effects of Social Threat on Stress-Related Cardiovascular Responses
The authors tested the hypothesis that the response-attenuating effects of affiliation under stress are limited to conditions that involve high social threat. Ninety-six young adult women were exposed to standardized psychological challenges in one of four conditions that involved two levels of social affiliation (alone or accompanied by a close friend) and two levels of social threat (variations in the social behavior and perceived status of the…
