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).

Based on previous findings in a U.S. sample, the present study validated the relationship between childhood trauma and dissociation, as well as the mediating role of disorganized attachment and the moderating role of mentalizing (i.e. self-concept clarity and reflective functioning) in a group of 569 Chinese adults (i.e. a community sample). Results demonstrated a mediating role for disorganized attachment relationships in linking childhood maltreatment and dissociative symptoms. Moreover, self-concept clarity moderated this mediating relationship. An interesting finding that differs from the U.S. sample is that reflective functioning did not play a moderating role between insecure attachment and dissociation in Chinese adults. Chinese culture places greater emphasis on collectivism, altruism, and other-oriented, and thus the protective effect of the reflective function may not be as effective as in an individualistic culture. This study provides evidence for a better understanding of the relationship between childhood trauma, attachment, dissociation, and the moderating role of mentalizing in an Eastern culture, and it opens the door to further research examining whether more Western (such as the U.S.) and Eastern (particularly Chinese) relationships are similar in both social and clinical psychology.

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.

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.

Attachment anxiety can decline in relationships but little is known about how or why. A new framework—the Attachment Security Enhancement Model (ASEM)—suggests that what allays current (momentary) insecurity may not necessarily reduce attachment anxiety across time. This article differentiates momentary versus extended attachment processes by examining concurrent versus longitudinal associations. Cohabitating partners ( N = 137 couples) were examined over a 2-year period as they became first-time parents, a transition that could change attachment tendencies. Consistent with ASEM predictions: (1) Anxiously attached spouses who perceived more proximal and sensitive reassurance from their partners felt less concurrent attachment anxiety but not less anxiety across time, and (2) attachment anxiety declined across time when spouses derived personal competence and self-efficacy from their new parenting role. These results document an important distinction between mitigating insecure thoughts and feelings that might reinforce attachment anxiety, versus encountering new experiences that may actually revise chronic insecurity.

In this study of 624 adult participants from the general population (i.e., a community sample), we examine adult disorganized attachment, a construct that can now be measured on a self-report scale, and its linkage between child abuse to dissociation. Prior research has demonstrated that child abuse is positively associated with adult disorganized attachment, which in turn is linked to a variety of externalizing and internalizing behaviors (e.g., depression, anxiety) in adulthood. Based on the literature regarding self-concept, we further consider that having an integrated sense of self is crucial in examining how having an adult disorganized attachment could result in dissociative symptoms. We consider two measures representing an unintegrated sense of self - self-concept clarity and reflective functioning - and find that both play a role in moderating the mediating effects of adult disorganized attachment. Specifically, lower levels of clarity were associated with higher levels of dissociation in our sample, and reflective functioning played a more nuanced and complex role in examining moderated mediation in our sample. Overall, using moderated mediation analysis, we found support for our hypotheses.

D the past five decades, few theories in psychology have generated as much interest, research, and debate as attachment theory (Bowlby, 1969/1982, 1973, 1980, 1988) and its recent extensions (see Cassidy & Shaver, 2016). Attachment theory is an extensive, inclusive theory of personality and social development “from the cradle to the grave” (Bowlby, 1979, p. 129). Being a lifespan theory, it is relevant to several areas in psychology, including developmental, personality, social, cognitive, neuroscience, and clinical. Because attachment theory covers the entire life course, it has several fundamental principles and core hypotheses, most of which address how and why people think, feel, and behave in particular ways within relationships at different points of their lives. Given the focus of this volume, our primary goal in this chapter is to provide a brief, representative overview of the key principles and central hypotheses that underlie attachment theory, both as originally articulated by Bowlby and his contemporaries (e.g., Ainsworth, Blehar, Waters, & Wall, 1978) and as expanded upon in recent theory and research (Cassidy & Shaver, 2016). Attachment theory has two major components: (1) a normative component, which explains modal (species-typical) attachment processes and patterns of behavior in humans, and (2) an individual-difference component, which explains individual deviations from modal processes and behavioral patterns. Most of the major principles and hypotheses we discuss in this chapter are normative ones, but we also highlight principles associated with well-established individual differences in attachment patterns (in children) and attachment orientations (in adults), including how they are related to a host of personal and relational processes and outcomes. We began our work on this chapter by surveying the theoretical and empirical literature on attachment processes across the lifespan and generated an initial list of potential principles and hypotheses. We then asked several leading attachment scholars working in different areas of psychology (e.g., clinical, developmental, personality, social) to indicate what they thought were the most important principles/ hypotheses.1 Informed by this information, we next identified what we believe are nine of the most important, foundational principles and hypotheses that serve as the foundation of attachment theory (see Table 12.1, which serves as a guide to the following discussion).

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.

Romantic relationships are one of the most important sources of well-being. Unfortunately, many people who begin relationships with high hopes later find that they are unhappy but unwilling or unable to leave. Why do people remain in unsatisfactory relationships? The present research examined whether elevated fear of change in anxiously attached individuals is associated with greater commitment to unsatisfying relationships. We found that fear of change mediated the association between attachment anxiety and commitment to relationships, and that fear of being alone was a serial mediator for the anxiety to commitment association along with fear of change.

The stress that arises during the transition to parenthood often places significant strain on marriages that can result in marital problems such as aggression victimization. In this research, we use an I3 framework to identify specific partner variables that are likely to promote physical aggression victimization across the transition to parenthood. Examining both intercepts (i.e., mean levels of aggression victimization estimated at childbirth) and slopes (e.g., changes in aggression victimization estimated over time), we find support for a three-way interaction anticipated by the I3 framework. Specifically, male partners were more likely to report being the victim of aggression at childbirth and also during the 24 months that followed when their female partner reported experiencing greater parental stress (an instigator to aggression in the I3 framework), greater relationship-specific attachment avoidance (an impellor to aggression), and lower relationship satisfaction (the lack of an inhibitor to aggression). Implications for the prevention of marital aggression associated with these I3 factors are discussed.

The transition to parenthood is a stressful life event that often leads to decreases in relationship satisfaction over time. Guided by the Stress Buffering Model, we examined how pregnancy intention and humor use are associated with relationship satisfaction across the transition to parenthood using a multi-wave longitudinal design. First-time parents were initially assessed prenatally and then every 6-month postpartum for 2 years. Six months after birth, each couple was video-recorded engaging in two support discussions where each partner’s use of different humor styles was observed and rated. The results revealed a positive association between affiliative humor use (assessed at 6-month postpartum) and relationship satisfaction (assessed across the entire transition) for men and women. For men only, there was an interaction between pregnancy intention (assessed prenatally) and aggressive humor use (assessed 6-month postpartum). Specifically, when the pregnancy was unplanned, men who displayed higher levels of aggressive humor at 6-month postpartum reported higher overall relationship satisfaction. There also was a significant interaction between men’s (but not women’s) affiliative humor use and pregnancy intention, such that when men reported an unplanned pregnancy, their greater use of affiliative humor buffered declines in their relationship satisfaction. These findings suggest that, for men, greater use of affiliative humor appears to forestall declines in their relationship satisfaction. More broadly, different forms of humor may promote or sustain higher levels of relationship satisfaction in men across the chronically stressful transition to parenthood because they serve key communicative functions.

Although attachment security is relatively stable over time, individuals do experience significant within-person variation in their attachment security across time. No research to date, however, has assessed the relational consequences of within-person variation (fluctuations) in attachment security toward a specific attachment figure. Study 1 (N = 409) first examined whether attachment security was associated with individuals' expectations that their current intimate relationship would be stable and consistent over time (vs. inconsistent and unstable). Studies 2 and 3 extended this by examining the prevalence and consequences of actual within-person variation (fluctuations) in relationship-specific attachment security toward an intimate partner in 2 multiwave longitudinal studies that assessed individuals (Study 2, N = 324) and couples (Study 3, N = 171 dyads). The results indicate that secure individuals (those low in attachment anxiety or attachment avoidance) expect their current relationship to remain relatively stable and consistent over time (Study 1). However, Studies 2 and 3 demonstrated that most individuals do experience fluctuations in their relationship-specific attachment security. Moreover, greater fluctuations predict declines in relationship satisfaction (Studies 2 and 3) and increases in relationship distress (Study 3) over time, but primarily for secure individuals (those low in baseline attachment anxiety or attachment avoidance). This set of findings highlight the importance of examining within-person fluctuations in attachment security, which are associated with declines in trajectories of relationship wellbeing, particularly for secure individuals who anticipate greater stability in their relationships.

In this article, we discuss theory and research on how individuals who have insecure adult romantic attachment orientations typically think, feel, and behave when they or their romantic partners encounter certain types of chronic or acute stress. We first review basic principles of attachment theory and then discuss how two forms of attachment insecurity-anxiety and avoidance-are associated with unique patterns of emotion regulation in response to certain types of threatening/distressing situations. We then discuss a diathesis-stress process model that has guided our research, highlighting studies that provide support for certain pathways of the model.

Research on disorganized attachment has indicated that for children, adolescents, and in early adulthood, dissociative symptoms tend to be associated with disorganized attachment. Additionally, empirical evidence has supported theoretical models suggesting that childhood maltreatment and concurrent abuse exacerbate the effects of disorganization, interacting to enhance dissociative effects. This literature is developmental in nature and does not make use of a self-report measure of disorganized attachment for adults, making it difficult to determine whether similar relationships exist in adulthood. We fill this gap, demonstrating to social and personality psychologists that a self-report measure of disorganization replicates the results for a community sample of adults. We employ a Bayesian approach to analyze our data.
