Health during Relationship Transitions: Policy Implications for Dating, New Parenthood, and Bereavement.

Romantic relationships impact individuals' mental and physical health across the lifespan. The link between relationships and health may be especially intertwined during transitions. Examining three seasons of romantic relationships-dating, the transition to parenthood, and bereavement-links each season with health.

Effects of a mild inflammatory challenge on cytokines and sickness behavior: A randomized controlled trial using the influenza vaccine.

The influenza vaccine has reliably been associated with mild, within-person increases in inflammation. However, the field lacks rigorous experimental work comparing the effects of the influenza vaccine to a placebo control on changes in plasma inflammatory cytokines and self-reported sickness behavior. In a double-blind, randomized, placebo-controlled trial, 102 participants received either the influenza vaccine or saline placebo.

Differential effects of social versus monetary incentives on inhibitory control under acute inflammation.

While the impact of chronic, low-grade inflammation on cognitive functioning is documented in the context of neurodegenerative disease, less is known about the association between acute increases in inflammation and cognitive functioning in daily life. This study investigated how changes in interleukin-6 (IL-6) levels were associated with performance on an inhibitory control task, the go/no-go task. We further examined whether the opportunity to earn different incentive types (social or monetary) and magnitudes (high or low) was associated with differential performance on the task, depending on IL-6 levels.

Do inflammation and relational motivation coordinate having better sex? The interplay between C-reactive protein and relational approach motivation on sexual well-being.

Much evidence on heightened inflammation and social behavior focuses on social withdrawal. Building on recent theory (Muscatell and Inagaki, 2021), we focused instead on the socially affiliative experience of sex. We investigated the interplay between immunology and motivation on sexual well-being among 158 individuals in romantic relationships.

Higher interleukin-6 is associated with greater momentary social connection in close relationships in daily life.

Recent evidence has documented associations between higher levels of inflammation and social approach behaviors toward close others in laboratory-based tasks. Yet it is unknown if this translates to interactions with close others in daily life. Given that momentary experiences of social connection have both relational and health consequences, this is a critical gap in our knowledge.

The roles of inflammation, affect, and interoception in predicting social perception.

"Sickness behavior" is an orchestrated suite of symptoms that commonly occur in the context of inflammation, and is characterized by changes in affect, social experience, and behavior. However, recent evidence suggests that inflammation may not always produce the same set of sickness behavior (e.g.

The Basic Psychological Need Satisfaction and Frustration Scales probably do not validly measure need frustration.

In basic psychological needs theory (BPNT), the separable constructs of need satisfaction and need frustration are theorized as pivotally related to psychopathology and broader aspects of well-being. The Basic Psychological Need Satisfaction and Frustration Scales (BPNSFS; Chen et al., 2015) have rapidly emerged as the dominant self-report measure in the BPNT domain, with translated versions available in a wide range of languages and a plethora of versions adapted for specific populations and life contexts.

Everyday co-presence with a romantic partner is associated with lower C-reactive protein.

Social relationships are an important driver of health, and inflammation has been proposed as a key neurobiological mechanism to explain this effect. Behavioral researchers have focused on social relationship quality to further explain the association, yet recent research indicates that relationship quality may not be as robust a predictor as previously thought. Here, building on animal models of social bonds and recent theory on close relationships, we instead investigated merely being in the physical presence of one's romantic partner.

Inflammatory reactivity to the influenza vaccine is associated with changes in automatic social behavior.

Recent evidence suggests differential patterns of social behavior following an inflammatory challenge, such that increases in inflammation may not uniformly lead to social withdrawal. Indeed, increases in inflammation have been associated with enhanced self-reported motivation to approach a specific close other, and greater neural sensitivity to positive social cues. However, no known studies have examined the association between inflammation in response to an inflammatory challenge and social behavior in humans, nor has past research examined specifically how approach and withdrawal behavior may differ based on whether the target is a close other or stranger.

Perceived Partner Responsiveness Forecasts Behavioral Intimacy as Measured by Affectionate Touch.

Affectionate touch is an important behavior in close relationships throughout the lifespan. Research has investigated the relational and individual psychological and physical benefits of affectionate touch, but the situational factors that give rise to it have been overlooked. Theorizing from the interpersonal process model of intimacy, the current studies tested whether perceived partner responsiveness forecasts affectionate touch in romantic couples.
