Here one time, gone the next: Fluctuations in support received and provided predict changes in relationship satisfaction across the transition to parenthood.

Extant research has demonstrated that higher mean (average) levels of social support often produce robust relational benefits. However, partners may not maintain the same level of support across time, resulting in potential fluctuations (i.e., within-person variations across time) in support. Despite the theorizing and initial research on fluctuations in relationship-relevant thoughts, feelings, and behaviors, little is known about (a) who is most likely to fluctuate in support and (b) the degree to which fluctuations, in combination with and beyond mean levels, impact relationships across time. The current preregistered research examined two dyadic longitudinal samples of first-time parents undergoing the transition to parenthood, a chronically stressful time that often entails the provision and receipt of support involving one's partner. Across both studies, we found that individuals who reported greater mental health problems, more situational stress, and more destructive dispositional attributes tended to report lower mean levels and higher fluctuations in provided and received support at subsequent assessments. Moreover, we found that greater fluctuations in perceptions and observations of support predicted decreases in relationship satisfaction over time, above and beyond the effect of mean levels. Implications for theory and studying nonlinear effects in relationships are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The predictive significance of fluctuations in early maternal sensitivity for secure base script knowledge and relationship effectiveness in adulthood.

Attachment theory suggests that both the quality and consistency of early sensitive care should shape an individual's attachment working models and relationship outcomes across the lifespan. To date, most research has focused on the quality of early sensitive caregiving, finding that receiving higher quality care predicts more secure working models and better long-term relationship outcomes than receiving lower quality care. However, it remains unclear whether or how the consistency of early sensitive care impacts attachment working models and adult relationship functioning. In this research, we utilized data from the Minnesota Longitudinal Study of Risk and Adaptation to examine to what extent the quality (i.e., mean levels) and consistency (i.e., within-person fluctuations) in behaviorally coded maternal sensitive care assessed 7 times from 3 months to 13 years prospectively predicts secure base script knowledge and relationship effectiveness (i.e., interpersonal competence in close relationships) in adulthood. We found that larger fluctuations and lower mean levels of early maternal sensitivity jointly predict lower relationship effectiveness in adulthood via lower secure base script knowledge. These findings reveal that nonlinear models of early caregiving experiences more completely account for relationship outcomes across the lifespan, beyond what traditional linear models have documented. Implications for attachment theory and longitudinal methods are discussed.

New parental positivity: The role of positive emotions in promoting relational adjustment during the transition to parenthood.

The transition to parenthood can be a challenging time for new parent couples, as a baby comes with changes and stress that can negatively influence new parents' relational functioning in the form of reduced relationship satisfaction and disrupted partner social support. Yet, the transition to parenthood is also often experienced as a joyous time. In this research, we draw on the broaden-and-build theory of positive emotions to suggest that new parents' positive emotions are not merely an enjoyable distraction, but are instead central to their relational adjustment. Specifically, we hypothesized that new parents who experienced greater positive emotions would report enhanced relationship satisfaction and partner social support across time. To test these ideas, we drew on two dyadic and longitudinal studies of new parents. In Study 1, 104 couples (208 individuals) completed surveys across the course of 1 year, and in Study 2, 192 couples (384 individuals) completed surveys and a laboratory-based social support interaction over the course of 2 years. At each wave of data collection, participants completed assessments of positive emotions, relationship satisfaction, and partner social support. We examined how actor and partner positive emotions longitudinally predicted relational adjustment across time. Results demonstrated that, even when controlling for baseline levels of each outcome variable, greater actor reports of positive emotions prospectively predicted greater subsequent actor (a) relationship satisfaction, (b) perceptions of social support from the partner, and (c) enacted social support as rated by independent observers, a pattern that was especially prominent for fathers. These results suggest positive emotions may be a resource that fosters healthy relational adjustment during chronically stressful periods that threaten intimate relationships, including during the transition to parenthood.

Perceptions of partner responsiveness across the transition to parenthood.

This longitudinal study examined associations between perceptions of partner responsiveness and relationship satisfaction of each partner (new parents) across the first 2 years of a chronically stressful life event-the transition to parenthood. Responsiveness indexes the degree to which partners respond to each other with understanding, validation, and care. Consistent with prior work, lower ratings of responsiveness receipt and provision predicted declines in relationship satisfaction across the transition. These effects, however, were moderated by parental stress, such that among new parents who reported experiencing higher levels of parental stress, providing higher levels of responsiveness to partners was associated with declines in relationship satisfaction. Conversely, under lower stress, relationship satisfaction benefited from higher levels of both providing and receiving responsiveness. All of these effects held when controlling for both partners' levels of agreeableness, neuroticism, support-seeking, income, and work-family conflict. Post hoc moderation analyses revealed that high stress partners who reported providing higher responsiveness reported larger declines in relationship satisfaction if they scored higher in attachment avoidance or had more negative social exchanges with their partner. We discuss these novel stress moderation results in light of the need to and meaning of engaging in responsiveness, especially during chronically stressful periods of life.

Support Processes Predict Declines in Attachment Avoidance Across the Transition to Parenthood.

Attachment orientations in adulthood can change over time, but the specific circumstances that directly affect change are not well understood. Bowlby proposed that those circumstances involve the assimilation of information that is incongruent with an individual's existing attachment orientation and underlying working models. In this study, 137 couples transitioning to parenthood were followed across the first 2 years of their firstborn child's life, with both partners providing data at five time-points. Only changes in attachment avoidance were examined in this study. Consistent with predictions, downward changes in avoidance were associated with relationship events that introduced information inconsistent with avoidant working models. For example, people who provided more support to their partners declined in avoidance across the transition period. We discuss these findings and new directions needed to better understand when and how attachment orientations change during major life transitions.

Theoretical Boundary Conditions of Partner Buffering in Romantic Relationships.

Attachment insecurity is consequential for both personal and relationship wellbeing. Some research has documented that partner buffering can downregulate insecure individuals' immediate feelings of distress, allowing them to feel more secure at least temporarily. The benefits of partner buffering, however, may be limited by several contextual factors. In this article, we identify boundary conditions that may curb or amplify the benefits of partner buffering for both targets (those who receive buffering) and agents (those who enact buffering). We suggest that motivation, ability, and timing may all affect partner buffering outcomes for targets and agents. If partner buffering is delivered in an adaptive way that does not reinforce the target's insecure tendencies, it may help insecure targets learn that they can trust and depend on their partners (agents), which may facilitate greater security in targets. We recommend that future research consider these contextual factors and examine partner buffering as an inherently dyadic relationship process capable of enhancing attachment security.

Machine learning uncovers the most robust self-report predictors of relationship quality across 43 longitudinal couples studies.

Given the powerful implications of relationship quality for health and well-being, a central mission of relationship science is explaining why some romantic relationships thrive more than others. This large-scale project used machine learning (i.e., Random Forests) to 1) quantify the extent to which relationship quality is predictable and 2) identify which constructs reliably predict relationship quality. Across 43 dyadic longitudinal datasets from 29 laboratories, the top relationship-specific predictors of relationship quality were perceived-partner commitment, appreciation, sexual satisfaction, perceived-partner satisfaction, and conflict. The top individual-difference predictors were life satisfaction, negative affect, depression, attachment avoidance, and attachment anxiety. Overall, relationship-specific variables predicted up to 45% of variance at baseline, and up to 18% of variance at the end of each study. Individual differences also performed well (21% and 12%, respectively). Actor-reported variables (i.e., own relationship-specific and individual-difference variables) predicted two to four times more variance than partner-reported variables (i.e., the partner's ratings on those variables). Importantly, individual differences and partner reports had no predictive effects beyond actor-reported relationship-specific variables alone. These findings imply that the sum of all individual differences and partner experiences exert their influence on relationship quality via a person's own relationship-specific experiences, and effects due to moderation by individual differences and moderation by partner-reports may be quite small. Finally, relationship-quality change (i.e., increases or decreases in relationship quality over the course of a study) was largely unpredictable from any combination of self-report variables. This collective effort should guide future models of relationships.

Maternal sensitivity during the first 3½ years of life predicts electrophysiological responding to and cognitive appraisals of infant crying at midlife.

This study examined the predictive significance of maternal sensitivity in early childhood for electrophysiological responding to and cognitive appraisals of infant crying at midlife in a sample of 73 adults (age = 39 years; 43 females; 58 parents) from the Minnesota Longitudinal Study of Risk and Adaptation. When listening to an infant crying, both parents and nonparents who had experienced higher levels of maternal sensitivity in early childhood (between 3 and 42 months of age) exhibited larger changes from rest toward greater relative left (vs. right) frontal EEG activation, reflecting an approach-oriented response to distress. Parents who had experienced greater maternal sensitivity in early childhood also made fewer negative causal attributions about the infant's crying; the association between sensitivity and attributions for infant crying was nonsignificant for nonparents. The current findings demonstrate that experiencing maternal sensitivity during the first 3½ years of life has long-term predictive significance for adults' processing of infant distress signals more than three decades later.
