Evidence for a vicious socioemotional cycle of negative emotions and interpersonal conflict.

Unlabelled: Interpersonal and emotional functioning are closely linked and reciprocally influence one another. Contemporary integrative interpersonal theory (CIIT) offers a useful framework to conceptualize these patterns and guide interventions in cases where these patterns result in dysfunction. Stress processes offer several dynamic frameworks to guide empirical investigations using methods that allow for fine-grained analyses in the context of daily life.

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.

Sex-specific associations between childhood trauma and adult systemic inflammation in daily life.

Objective: Childhood trauma may contribute to lifelong health through chronic systemic inflammation. However, associations between childhood trauma and inflammation are mixed, indicating that distinct types of childhood trauma may relate to inflammation differently. Moreover, most studies use a single assessment of inflammatory markers that may not reliably estimate stable interindividual differences.

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 interactions statistically mediated this association - namely, (a) received support, the visible and deliberate assistance provided by others, and (b) pleasantness, the extent to which an interaction is positive, flows easily, and leads individuals to feel understood and validated. 591 United States adults completed a 3-week ecological momentary assessment protocol sampling characteristics of their everyday social interactions that was used to evaluate between-person average values and within-person daily fluctuations in everyday social interaction characteristics.

Stressor-evoked brain activity, cardiovascular reactivity, and subclinical atherosclerosis in midlife adults.

Background: Cardiovascular responses to psychological stressors have been separately associated with preclinical atherosclerosis and hemodynamic brain activity patterns across different studies and cohorts; however, what has not been established is whether cardiovascular stress responses reliably link indicators of stressor-evoked brain activity and preclinical atherosclerosis that have been measured in the same individuals. Accordingly, the present study used cross-validation and predictive modeling to test for the first time whether stressor-evoked systolic blood pressure (SBP) responses statistically mediated the association between concurrently measured brain activity and a vascular marker of preclinical atherosclerosis in the carotid arteries.

Methods: 624 midlife adults (aged 28-56 years, 54.
