Research on Marital Satisfaction and Stability in the 2010s: Challenging Conventional Wisdom

The role of oxytocin in mediating the relationships between social factors and chemotherapy-associated cognitive decline in female patients with breast cancer

While chemotherapy can cause debilitating side effects, social support, particularly that of an intimate partner, can be protective. This study examined the relationships between couple satisfaction and chemotherapy-associated subjective and objective cognitive decline in a cohort of breast cancer patients, in addition to the roles of other social factors. Because of oxytocin's role in social bonding and cognition, circulating oxytocin and oxytocin receptor gene expression in peripheral blood mononuclear cells were investigated as potential mediators. Partnered breast cancer patients (n = 48) completed cognitive assessments and provided blood samples at 3 timepoints: pre-chemotherapy, during chemotherapy, and post-chemotherapy. Participants completed a retrospective couple satisfaction questionnaire, provided information about partner duration as well as other social factors (e.g., number of people in the household, number of dependents under 18), and completed a retrospective perceived general social support questionnaire. Analyses were completed using linear mixed effects and regression models. More satisfaction in an intimate relationship related to both less subjective and objective cognitive decline over chemotherapy. Similarly, higher perceived social support related to less overall objective cognitive decline over chemotherapy, though this relationship was less robust than that observed with high couple satisfaction. Remarkably, circulating oxytocin decreased over chemotherapy but was only associated with partner duration and not with cognitive measures. This study suggests a potential benefit of social-directed interventions for the treatment of cognitive side effects of chemotherapy, either from an intimate partner or more generally. Furthermore, understanding biological mechanisms is important to develop novel preventative and interventional therapies to mitigate the adverse side effects of chemotherapy.

"Pay Me Back": Testing the Implications of Long-Term Changes and Partner Similarity in Exchange Orientation Within Intimate Relationships

Past research on intimate relationships suggests that exchange orientation-the tendency to expect direct reciprocation when providing a benefit-predicts lower relationship well-being. However, limited research has examined the long-term associations of this link or the effects of partner similarity in exchange orientation. The present research addressed this gap by employing a set of rigorous analyses on longitudinal data spanning 13 years from a national sample of romantic couples in Germany (N = 7,293 couples). Latent curve models with structured residuals (LCM-SR) revealed that romantic partners, on average, experienced a general decline in exchange orientation over the course of their relationship. Partners who showed slower declines in exchange orientation experienced steeper declines in relationship satisfaction. Within-person increases in exchange orientation predicted future decreases in relationship satisfaction. Dyadic response surface analyses (DRSA) indicated no evidence of similarity effects. Overall, these findings corroborate the adverse effects of exchange orientation on intimate relationships.

Stress Perception and Marital Instability Across the Family Life Cycle: An Actor-Partner Perspective

This study aimed to reveal the association between spousal stress perception and marital instability across different stages of the family life cycle, focusing on the actor and partner effects and exploring the mediating role of daily communication in this relationship. With rising divorce rates, it's essential to examine factors affecting marital instability. Drawing from the stress-divorce model, spouses' stress perception likely permeates into marriage via daily communication. It is important to consider challenges unique to different marital stages to understand variations among couples through the family life cycle. The study used the Perceived Stress Scale, the Primary Communication Inventory, and the Marital Instability Scale to survey 654 couples in the newlywed, couples with pre-school children, couples with school-age children, and empty-nest stages. The study revealed that the actor-partner effects between stress perception and marital instability were initially present in the early stages of marriage. As the duration of the marriage progressed, during the stages of pre-school age and school-age children, only actor effects existed. In the empty nest stage, the actor-partner effects gradually diminish. Throughout the life cycle, daily communication served as a mediating factor in the relationship between stress and marital instability. This research uncovers a dynamic evolution in the association between couples' stress perception and marital instability across marital longevity: at the beginning of marriage, spouses have interactive effects; at the stage with child(ren), the interactive effect diminishes; at the empty-nest stage, the role is imposed only through the medium of daily communication. Our research reveals that maintaining communication during all stages of marriage is key to effectively managing stress and maintaining marital instability.

Exploring the role of psychological flexibility in relationship functioning among couples coping with prostate cancer: a cross-sectional study

OBJECTIVE

Prostate cancer (PCa) is an external stressor that can affect both patients and partners, but dyadic research in this area is limited. This study, guided by the vulnerability-stress-adaptation model, examines how PCa distress affects relationship satisfaction through psychological flexibility and self-esteem.

METHODS

The study used a cross-sectional design with a total sample size of 314 dyads. The actor-partner interdependence model was applied to examine both actor and partner effects. Covariates were also examined.

RESULTS

PCa distress negatively predicted psychological flexibility in both patients ( β = - .93, p < .001) and partners ( β = - 0.70, p < .001). Psychological flexibility, in turn, positively predicted self-esteem in both patients ( β = 0.19, p < .001) and partners ( β = 0.19, p < .001). Self-esteem significantly predicted relationship satisfaction for both patients ( β = 0.22, p < .001) and partners ( β = 0.22, p < .001). The indirect effects of PCa distress on relationship satisfaction via psychological flexibility and self-esteem were significant for both patients ( β = - .093, p < .001) and partners ( β = - .078, p < .001). Additionally, a significant indirect effect of partners' PCa distress on patients' relationship satisfaction was observed ( β = - .055, p < .01).

CONCLUSION

The findings highlight the critical role of psychological flexibility and self-esteem in mediating the impact of PCa distress on relationship satisfaction for both patients and partners. Tailored interventions aimed at enhancing psychological flexibility to support relationship functioning in couples coping with PCa may be effective.

Explaining the prevalence of marital conflict: conceptual bifurcation and sociological explanations

Sociologists have investigated extensively marital conflict which is supposedly "antithesis" of marriage. However, there is little systematic reflection on how the coexistence of universal marriage and prevalent spousal discord in diverse cultural settings can possibly explained sociologically. This conceptual paper aims to address this issue by first critically reviewing how scholars have assessed the prevalence of marital conflict in human societies. This review is then extended to the conceptual elusiveness in gauging "marital conflict," arguing that the concept has been inadvertently bifurcated as (i) a constituent (oft-represented as a single global continuous measure) of certain critical consequential events within a marriage (e.g., divorce); and (ii) a predisposition (oft-represented in terms of a set of multifarious binary variables) in pair-bonding relationships that increases the likelihood of the occurrence of certain critical consequential events. Such conceptual bifurcation sheds light on two board distinctive approaches-roughly termed contextual and evolutionary-through which the coexistence of marriage formation and martial conflict can be sociologically explained. Implications are briefly discussed.

Positive Outcomes of Long-Term Relationship Satisfaction Trajectories in Stable Romantic Couples: A 10-Year Longitudinal Study

Growing evidence challenges the longstanding assumption of a universal decline in relationship satisfaction for all couples by demonstrating variability in the change. However, knowledge about how differential long-term trajectories of relationship satisfaction are associated with positive individual functioning is lacking. Using dyadic latent class growth analysis, we studied long-term trajectories of relationship satisfaction of N = 300 mixed-gender couples over 10 years and examined positive outcomes in latent subgroups. At the final assessment, partners reported on positive outcomes, specifically affect, mental health, and life satisfaction. Depending on their subgroup membership, couples systematically differed: Couples in the subgroup with high initial and relatively stable relationship satisfaction reported the most favorable outcomes-more positive affect, better mental health, and higher life satisfaction-as compared to subgroups with declining and/or lower relationship satisfaction. The findings show the importance of considering the variability in long-term relationship satisfaction trajectories and point to their relevance for positive functioning.

Couple relationship education content: What we have and what we are missing

Couple relationship education (CRE) has decades of research showing mixed results for participants. Various competing frameworks for CRE content have emerged in the development of the field, yet content has not been systematically investigated. Through an inductive content analysis of 15 different CRE programs, this study explored content themes and categories that are common across programs. Analysis found four themes throughout the programs: interactional skills, the self in the relationship, partner bonding, and relationship motivations. Categories for each theme were identified and are presented and discussed. Findings validate the primacy of teaching interactional skills within CRE including consistency in topics (e.g., communication training, conflict management). Other themes were also common (e.g., self in the relationship), though their categories were more diverse (e.g., self-care, expectations, personality). Several factors that have emerged as more significant in relationship theory and research were not well-represented in the content analysis (e.g., socioecological contexts, systemic patterns).

Love as a Commitment Device : Evidence from a Cross-Cultural Study across 90 Countries

Given the ubiquitous nature of love, numerous theories have been proposed to explain its existence. One such theory refers to love as a commitment device, suggesting that romantic love evolved to foster commitment between partners and enhance their reproductive success. In the present study, we investigated this hypothesis using a large-scale sample of 86,310 individual responses collected across 90 countries. If romantic love is universally perceived as a force that fosters commitment between long-term partners, we expected that individuals likely to suffer greater losses from the termination of their relationships-including people of lower socioeconomic status, those with many children, and women-would place a higher value on romantic love compared to people with higher status, those with fewer children, and men. These predictions were supported. Additionally, we observed that individuals from countries with a higher (vs. lower) Human Development Index placed a greater level of importance on romantic love, suggesting that modernization might influence how romantic love is evaluated. On average, participants worldwide were unwilling to commit to a long-term romantic relationship without love, highlighting romantic love's universal importance.

Racial discrimination predicts subjective cognitive decline: Perceived relationship support buffers the association

OBJECTIVES

Recent studies show that chronic exposure to racial discrimination increases the occurrence of subjective cognitive decline (SCD) among Black Americans. Little research, however, has examined potential for protective factors, such as perceived partner support, to buffer these effects.

METHODS

This study utilized longitudinal data over a 10-year period from the Family and Community Health Study (FACHS) to examine the associations between experiences of racial discrimination, marital status, partner support, and SCD, measured by the Everyday Cognition (ECog) Scale, among 286 middle-aged Black American women. Regression analysis and internal moderator analyses were employed to analyze the data.

RESULTS

About 31% were in married relationships. Thirty-four percent reported cognitive decline, especially in forgetting object locations and dates. Chronic discrimination predicted SCD, and for those in couple relationships, partner support buffered the adverse effects of discrimination, with those in warm and supportive relationships experiencing less SCD than those in relatively unsupportive relationships or not in a relationship.

CONCLUSIONS

The study's findings support the idea that racism influences SCD and underscores the importance of supportive couple relationships in promoting resilience. The results also highlight the potential value of culturally relevant family interventions and support strategies to reduce the impact of discrimination-induced stress on cognitive health.

Interpersonal dynamics of vocal fundamental frequency in couples: Depressive symptoms, anxiety symptoms, and relationship distress

Given the bidirectional association between psychopathology and relationship distress, an in-depth understanding of couples' interaction processes that contribute to psychopathology is needed. This study examined the interpersonal dynamics of vocally-encoded emotional arousal (fundamental frequency, f0) during couple conversations and their associations with depressive symptoms, anxiety symptoms, and relationship distress. Data from eight samples were pooled (N = 404 couples) to examine (a) overall trajectories of f0 across the interaction and (b) moment-by-moment intraindividual changes in and interpersonal reactivity to partners' f0. Multilevel growth models and repeated-measures actor-partner interdependence models demonstrated that individuals with more severe depression showed more synchronizing reactivity to their partners' f0 on a moment-by-moment basis, and their overall baseline level of f0 was lower. More severe relationship distress was associated with more steeply increasing trajectories of f0 and with greater synchronizing reactivity to partners' f0. Relative differences in depressive symptoms between the two members of a couple were associated with interpersonal dynamics of f0 as well. There were no associations with anxiety symptoms. Thus, depressive symptoms were associated with characteristic interpersonal dynamics of vocally-encoded emotional arousal; yet, most consistent associations emerged for relationship distress, which future studies on individual psychopathology should take into account.

Bidirectional or unidirectional? Longitudinal associations between external stressors, perceived spousal support, and marital instability

Based on three annual waves of data from 268 Chinese newlyweds (Mage = 29.59, SD = 3.25 for husbands; Mage = 28.08, SD = 2.51 for wives), the present study examined the bidirectional associations between external stressors, perceived spousal support, and marital instability by using a three-wave, cross-lagged approach. Results indicated bidirectional associations between external stressors and marital instability, and a unidirectional association linking marital instability to perceived spousal support. Additionally, external stressors at Wave 2 mediated the association between external stressors at Wave 1 and marital instability at Wave 3. Taken together, the present study contributes to an emerging body of research aimed at clarifying: (a) the directionality of the associations between external stressors, perceived spousal support, and marital instability; (b) how external stressors cumulatively affect the development of marital instability. Our study extends the Vulnerability-Stress-Adaptation (VSA) model and has developmental implications for promoting marital relationships in non-Western couples.

Interpersonal relationships, PNI, and health: Seeds in the 1980s, fruiting trees today

In this contribution to the Special Issue, I highlight how Janice Kiecolt-Glaser's research in the 1980s planted the seeds for two areas of social relationships and health research: loneliness and intimate/marital relationships. I review the foundational "seed" studies from the mid-to late-1980s, the research "saplings" that sprouted and grew during the subsequent twenty years, and the "mature trees" that have gone on to fruit and grow their respective areas of inquiry over the past twenty years. In addition to highlighting the mature trees that have borne rich empirical fruit, my other goal for this contribution is to draw attention to ideas and concepts from Kiecolt-Glaser's work and writing that merit further conceptual and empirical examination in the next generation of research on social relationships, psychoneuroendocrinology, psychoneuroimmunology, and health.

Psychoneuroimmunology in multiple myeloma and autologous hematopoietic stem cell transplant: Opportunities for research among patients and caregivers

Multiple myeloma (MM) is an incurable cancer and is the leading indication for autologous hematopoietic stem cell transplantation (HSCT). To be eligible for HSCT, a patient must have a caregiver, as caregivers play a central role in HSCT preparation and recovery. MM patients remain on treatment indefinitely, and thus patients and their caregivers face long-term challenges including the intensity of HSCT and perpetual therapy after transplant. Importantly, both patients and their caregivers show heightened depressive and anxiety symptoms, with dyadic correspondence evidenced and caregivers' distress often exceeding that of patients. An extensive psychoneuroimmunology (PNI) literature links distress with health via immune and neuroendocrine dysregulation as well as biological aging. However, data on PNI in the context of multiple myeloma - in patients or caregivers - are remarkably limited. Distress in MM patients has been associated with poorer outcomes including higher inflammation, greater one year post-HSCT hospital readmissions, and worse overall survival. Further, anxiety and depression are linked to biological aging and may contribute to the poor long-term health of both patients and caregivers. Because MM generally affects older adults, individual differences in biological aging may represent an important modifier of MM biology and HSCT treatment outcomes. There are a number of clinical scenarios in which biologically younger people could be prescribed more intensive therapies, with potential for greater benefit, by using a personalized cancer therapy approach based on the quantification of physiologic reserve. Further, despite considerable psychological demands, the effects of distress on health among MM caregivers is largely unexamined. Within this context, the current critical review highlights gaps in knowledge at the intersection of HSCT, inflammation, and biological aging in the context of MM. Research in this area hold promise for opportunities for novel and impactful psychoneuroimmunology (PNI) research to enhance health outcomes, quality of life, and longevity among both MM patients and their caregivers.

Reciprocal associations between commitment, forgiveness, and different aspects of marital well-being among Chinese newlywed couples

This study examined the reciprocal prospective associations between commitment, forgiveness, and different aspects of marital well-being (marital satisfaction and marital instability) among Chinese newlywed couples and the gender differences in these associations. The Vulnerability-Stress-Adaptation (VSA) model posits reciprocal associations between adaptive processes and relationship satisfaction. However, the directionality of the associations between adaptive processes and marital satisfaction may differ from the associations between adaptive processes and marital instability in Chinese societies due to the emphasis on relationship maintenance. Based on three annual waves of data from 268 Chinese newlywed couples (Mage = 29.59, SD = 3.25 for husbands; Mage = 28.08, SD = 2.51 for wives), a cross-lagged approach was used to examine the reciprocal associations between commitment, forgiveness, and marital satisfaction/instability. We found: (a) reciprocal associations between commitment/forgiveness and marital satisfaction (wives only); (b) reciprocal associations between forgiveness and marital instability (husbands only); and (c) wives' commitment at Wave 2 mediated the association between wives' commitment at Wave 1 and wives' marital satisfaction at Wave 3. Extending the VSA model, findings suggest different reciprocal associations between commitment, forgiveness, and different aspects of marital well-being among Chinese newlywed couples. Results highlight the important role of culture and gender in marital relationships and clinical practice.

The Relationship between Addictive Use of Short-Video Platforms and Marital Satisfaction in Older Chinese Couples: An Asymmetrical Dyadic Process

Increasing evidence indicates that the addictive use of social media can have a detrimental effect on marital satisfaction, due mainly to the decrease in time and focus given to one's spouse. However, the impact of social media use among older couples remains under-investigated, and the research that does exist relies on individual-level data that do not allow the exploration of the dynamics between the dyadic partners. Therefore, the present study focused on older adults' use of short-video platforms, as these have been shown to be particularly addictive for older adults. A sample of 264 older couples was gathered (meanage = 68.02, SD = 8.68), and both spouses completed surveys reporting addictive use of short-video platforms, negative emotions, and marital satisfaction. Using an actor-partner interdependence model, we found an asymmetrical dyadic process in that the addictive use of short-video platforms by the wives was not only related to their own negative emotions, but also those of their spouse, as well as to decreased marital satisfaction. Meanwhile, addictive use by the husbands seemed to relate only to their own increased negative emotions, as well as to decreased marital satisfaction. Together, the findings from this study reveal dyadic dynamics with delineated pathways through which the addictive use of short-video platforms can damage older couples' interactive processes and marital satisfaction.

A day in the life: Couples' everyday communication and subsequent relationship outcomes

Understanding how communication processes contribute to well-functioning versus distressed couple relationships has relied largely on brief, laboratory-based conversations. Harnessing technological advancements, the present study extends the literature by capturing couples' naturalistic communication over one full day at Time 1 (T1). This study tested associations between data-driven categories of couple communication behaviors and relationship outcomes (i.e., relationship aggression, satisfaction, and dissolution) at Time 2 (T2), approximately 1 year later. Emerging adults in different-gender dating couples (n = 106 couples; 212 individuals; Mage = 22.57 ± 2.44; M relationship length = 30.49 months ± 24.05; 72.2% non-White) were each provided a smartphone programmed to audio record approximately 50% of a typical day. Interactions between partners were transcribed and coded for location, activity, affect, and a range of positive and negative communication behaviors for each partner. Even after controlling for T1 assessments of the relevant outcome, one's own hostility and one's partner's hostility at T1 were each positively associated with T2 relationship aggression and negatively associated with T2 relationship satisfaction. One's own withdrawal at T1 was positively associated with T2 relationship aggression perpetration, whereas one's partner's withdrawal was negatively linked to relationship satisfaction at T2. One's own playfulness, unexpectedly, was linked to lower subsequent relationship satisfaction. Withdrawal increased the likelihood of relationship dissolution, whereas warmth and playfulness decreased the likelihood of dissolution. The relevance of couples' ordinary, everyday communication for meaningful relationship outcomes is discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Doing it all: Effects of Family Responsibilities and Marital Relationship Quality on Mothers' Ambulatory Blood Pressure

BACKGROUND

The shared provider responsibility between married couples does not translate to equally shared division of childcare (CC) and household labor. While some marriages contain highly positive aspects, marriages may also simultaneously contain both positive and negative aspects. The negativity in these relationships can negate the positivity and could potentially lead to the detriment of mothers' health.

PURPOSE

We examined mothers' ambulatory blood pressure (ABP) associated with their marital relationship quality and perceived equity with her spouse on CC and household tasks.

METHODS

We investigate these associations using a mixed multilevel model analysis on a sample of 224 mothers in heterosexual marriages, all of whom had children under the age of 18 years currently living in the home.

RESULTS

Mothers' perception of equity in the division of CC responsibilities contributed to lower ABP. Additionally, mothers in supportive marital relationships (low negativity and high positivity) had lower ABP than those in ambivalent relationships (both high negativity and positivity). There was a crossover interaction such that the effect of relationship quality on ABP was moderated by the perception of equity in the division of CC. For mothers who report doing all the CC, they had lower ABP if they had a supportive marital relationship compared with mothers in ambivalent relationships. Whereas mothers who report more equity in CC and have a supportive relationship have higher ABP compared with mothers in ambivalent relationships.

CONCLUSIONS

This study has implications related to dynamics within marital relationships. These results demonstrate important relational influences on mothers' ABP.

Development and psychometric properties of the Couple Interaction Pattern Scale

This study developed the Couple Interaction Pattern Scale (CIPS) based on the interpersonal theory, comprising five subscales: friendly complementary (FC), hostile complementary (HC), mutual hostile-dominant (MHD), friendly-dominant eliciting hostile-submissive (FDHS), and hostile-dominant eliciting friendly-submissive (HDFS). The psychometric properties of the CIPS were examined through three independent studies. Study one conducted item reduction and preliminary analysis using a sample of 662 married individuals, with an additional 80 married individuals for test-retest reliability assessment. Study two validated the scale through 1207 married individuals. In study three, the effect of couple interaction pattern (CIP) on marital quality was analyzed among 310 newlywed couples using the actor-partner interdependence model (APIM). Results supported the construct validity, acceptable internal consistency, and test-retest reliability of the CIPS. Besides, concurrent validity was also proved by associations with conflictual communication patterns, marital quality, stability, emotional connection, and perceived partner support. APIM analysis also supported the association between CIP and marital quality.

Typologies of duocentric networks among low-income newlywed couples

The social networks surrounding intimate couples provide them with bonding and bridging social capital and have been theorized to be associated with their well-being and relationship quality. These networks are multidimensional, featuring compositional (e.g., the proportion of family members vs. friends) and structural characteristics (e.g., density, degree of overlap between spouses' networks). Most previous studies of couple networks are based on partners' global ratings of their network characteristics or network data collected from one member of the dyad. This study presents the analysis of "duocentric networks" or the combined personal networks of both members of a couple, collected from 207 mixed-sex newlywed couples living in low-income neighborhoods of Harris County, TX. We conducted a pattern-centric analysis of compositional and structural features to identify distinct types of couple networks. We identified five qualitatively distinct network types (wife family-focused, husband family-focused, shared friends, wife friend-focused, and extremely disconnected). Couples' network types were associated with the quality of the relationships between couples and their network contacts (e.g., emotional support) but not with the quality of the couples' relationship with each other. We argue that duocentric networks provide appropriate data for measuring bonding and bridging capital in couple networks.

Closeness Discrepancies in Couple Relationships: A Dyadic Response Surface Analysis

Individuals can differ in the degree of closeness they desire in their romantic relationships: Some people may perceive their current level of closeness as just right, whereas others may feel not close enough or too close to their partners (referred to as negative and positive closeness discrepancy, respectively). This study (N = 1,177 individuals from 748 couples) examined the implications of closeness discrepancies for subjective relationship quality (SRQ) using dyadic response surface analysis. The analyses found evidence for linear, but not broad, closeness discrepancy effects: SRQ was lower for individuals reporting more negative closeness discrepancies and, independent of this actor effect, for individuals with partners who reported more negative closeness discrepancies. These results suggest that low levels of closeness paired with a strong desire for closeness can impair both partners' relational well-being.

Subjective emotion trajectories in couple therapy and associations with improvement in relationship satisfaction

Existing couple therapies are generally effective for reducing romantic relationship distress and divorce, but therapy outcomes remain poor for many. Outcomes can be improved through greater understanding of session-by-session therapeutic processes, particularly in real-world treatment settings. Modern couple therapy models commonly emphasize the importance of emotional experiences as key change processes, yet few empirical studies have tested the merits of this focus. The present study addresses this limitation by examining trajectories of subjective emotions and their association with change in a key relationship outcome, relationship satisfaction, among military veterans and their partners at a VA Medical Center. Partners rated their relationship satisfaction prior to couple therapy sessions and subjective emotions immediately after sessions. Consistent with hypotheses, both hard (e.g., anger) and soft (e.g., sadness) negative emotions decreased significantly over the course of therapy. Those couples with greater decreases in hard negative, but not soft negative, emotions showed significantly more improvement in relationship satisfaction. Positive emotions did not significantly change across couples in general, but those couples whose positive emotions did increase also showed more improvement in relationship satisfaction. These results suggest change in subjective emotions may be one process underlying improvement in couple therapy and lend empirical support to the emphasis on emotion-based change processes underlying acceptance-based and emotion-focused couple therapies.

Emotion Regulation in Couples Across Adulthood

Intimate relationships are hotbeds of emotion. This article presents key findings and current directions in research on couples' emotion regulation across adulthood as a critical context in which older adults not only maintain functioning but may also outshine younger adults. First, I introduce key concepts, defining qualities (i.e., dynamic, coregulatory, bidirectional, bivalent), and measures (i.e., self-report versus performance-based) of couples' emotion regulation. Second, I highlight a socioemotional turn in our understanding of adult development with the advent of socioemotional selectivity theory. Third, I offer a life-span developmental perspective on emotion regulation in couples (i.e., across infancy, adolescence and young adulthood, midlife, and late life). Finally, I present the idea that emotion regulation may shift from "me to us" across adulthood and discuss how emotion regulation in couples may become more important, better, and increasingly consequential (e.g., for relationship outcomes, well-being, and health) with age. Ideas for future research are then discussed.

"How did you stay together so long?" Relationship longevity, a cross-generational qualitative study

This global qualitative study adopted a cross-generational approach considering key factors contributing to relationship longevity. Relatively few studies consider factors leading to relationship longevity as articulated by couples themselves, and there is a paucity of research considering young couples' questions regarding relationship longevity. This study has two sample groups. In sample one (n = 137) we asked individuals in relationship of 3-15 years questions they would ask couples in marriages of 40+ years. We then asked our second sample of coupled individuals married 40+ years (n = 180) these questions. The primary question from the younger couples to couples in long-term marriages regarded their "secret" to relationship longevity. This study focuses on this one question and coupled individuals' self-articulation of their "secrets" to relationship longevity. The top seven were (1) commitment, (2) altruism, (3) shared values, (4) good communication, (5) compromise: give and take, (6) love, and (7) never give up. The clinical implications for couple therapists are discussed.

Relationship standards and Malay Muslim couples' marital satisfaction

Relationship standards are beliefs about what is important in high-quality couple relationships. Clarifying standards cross-culturally informs theory about relationship quality and goals for culturally appropriate couple therapy. The current study assessed four standards (Couple Bond, Family Responsibility, Relationship Effort, and Religion) in n = 113 Malay Muslim couples, and the association of those standards with marital satisfaction. All four standards were strongly endorsed, Religion was the most strongly endorsed, and there were minimal sex differences. Separate actor-partner interdependence models showed actor effects of all four standards on own satisfaction for husbands and wives, partner effects of three of the four husbands' standards (not Relationship Effort) on wives' satisfaction, but no partner effects of female standards on male satisfaction. The findings underscore the importance of all four standards in Malay Muslim marriages and that attention to all these standards might need to be part of couple therapy with Malay couples.

The Power of Mindfulness: Examining Power Imbalances, Mindfulness, and Couples' Relational and Sexual Well-Being

Perceptions of power imbalance are common in relationships. We used the relational model of mindfulness to examine links between marital perceptions of power, relational and sexual well-being and to evaluate whether trait mindfulness and sexual mindfulness moderate these associations. Using a nationally representative sample (N = 1,519 couples at Wave III) of mixed-sex newlywed couples, an actor-partner-interdependence model indicated that trait mindfulness and state sexually mindful awareness buffered the link between men's and women's own perceived power imbalance and relational well-being. Sexually mindful non-judgment, however, accentuated the negative association between perceived power imbalance and sexual well-being for men. We discuss the need for therapists to consider the need to encourage mindful awareness to attenuate perceptions of power imbalances and to evaluate how sexually mindful non-judgment influences men's feelings of sexual well-being. Therapeutic implications of these findings are also discussed.

Research on Intelligent English Education Based on the Short Video Recommendation Algorithm

In order to solve the problems of English education in the form of a short video, a research method of English intelligent education based on a short video recommendation algorithm was proposed. The recommendation system is a branch of artificial intelligence data mining, which improves the efficiency of short videos for English learning. The density ratio of users and video scoring matrix was 1000000/(1030 × 9394) = 10.3%. The dataset was a relatively sparse matrix. The original dataset was randomly divided into the training set and the test set, accounting for 80% and 20%, respectively. Then, the results of the short video recommendation algorithm were elaborated based on time weighting. Finally, the intelligent initial question bank of English intelligent education based on a short video recommendation algorithm was elaborated, which provided a guarantee for the promotion of short videos in English education.

Theory of brain complexity and marital behaviors: The application of complexity science and neuroscience to explain the complexities of marital behaviors

The extant theories on the quality and stability of marital relationships have some difficulties in explaining some of the complexities of marital behaviors. The present article is an initial attempt to explain the complexities of marital behaviors based on the science of complexity and neuroscience. This article proposes a new theoretical framework relying on this simple argument that marital behaviors, as one of the most complex human behaviors, are the product of one's brain's complex adaptive system (CAS). Hence, to understand the complexities of marital behaviors, a movement toward familiarity with the brain's CAS involved in marital behaviors needs to be started. The article presents the theory of brain complexity and marital behaviors (BCM) and outlines its assumptions, concepts, and propositions. Then, BCM is compared with the extant theories on happy and stable marriage, and finally, it was concluded by discussing the testability and the potential application of the theory. This article might inspire interdisciplinary studies of marital relationships, complex systems, and neuroscience and may have considerable practical implications.

The roles of self-regulation and partner regulation on romantic relationship quality

Research into self-regulation and partner regulation strategies has largely involved parallel lines of research, thus, it is difficult to determine the relative contribution of both forms of regulation when it comes to relationship outcomes. Therefore, the question remains as to which form of regulation is more strongly associated with relationship quality; is it more important to focus on adaptive self-regulation or adaptive strategies to regulate one's partner? The current research addresses this important gap by comparing the relative associations of adaptive self-regulation and adaptive partner regulation strategies on romantic relationship quality. A community sample of mixed gender couples (N = 114) who were predominantly satisfied with their current relationships - but nonetheless still experienced relationship conflict - were administered self-report assessments of various self-regulation and partner regulation strategies as well as a measure of relationship quality. Couples also participated in a videotaped discussion of an unresolved relationship issue that was scored by trained coders for verbal and nonverbal indicators of self-regulation and partner regulation strategies. Actor-partner interdependence modeling revealed that for both men and women, adaptive self-regulation strategies were positively associated with their own evaluations of relationship quality as well as their partner's relationship quality. In contrast, engaging in adaptive partner regulation strategies was not significantly associated with men's or women's own, or their partner's relationship quality. Findings highlight the importance of focusing on self-regulation in relationships, as it is these strategies, over partner regulation strategies, that have more positive implications for the relationship quality experienced by typically satisfied couples.

Relationship quality and family formation in Europe

The increase in cohabitation and nonmarital childbearing across Europe has raised questions about who still marries either before or after having a child. Although prior studies have addressed the sequence of marriage and childbearing, few have examined the role of relationship quality in these transitions. Here we employ a cross-national perspective to study the association between relationship quality and marriage and/or first birth within cohabitation. Using the Generations and Gender Survey and UK Household Longitudinal Study, we study seven European countries (Austria, France, Hungary, Netherlands, Norway, Sweden, and UK). We employ competing risk hazard models to follow respondents as they 1) transition from cohabitation into marriage or conception (or separation); 2) transition to marriage (or separation) after having a birth within cohabitation. Results show that cohabitors with higher relationship quality are more marriage prone than those in lower quality relationships in Austria, France, Hungary, and the UK, but not in the Netherlands, Norway and Sweden. Instead, higher relationship quality is associated with higher conception risks in cohabitation in Sweden. After childbearing, we find a positive association between relationship quality and marriage among cohabiting parents in the Netherlands, Norway, Sweden, and the United Kingdom. These results suggest that marriage is still important for couples with higher quality relationships; however, in countries where cohabitation is widespread, the timing of marriage may have shifted to after childbearing.

Dyadic Profiles of Sexual Satisfaction among Chinese Newlywed Couples over Time

Although sexual satisfaction is a defining feature of marriage, research has consistently found that sexual satisfaction declines over time. Recently, however, emerging findings provide a more optimistic perspective on sexual satisfaction development by suggesting that couples may follow diverse sexual satisfaction trajectories. Using Dyadic Latent Class Growth Analysis, the current study is among the first to examine heterogeneity in couples' sexual satisfaction trajectory patterns during the early years of marriage and the first to do so in a non-Western context. Specifically, we establish distinct trajectory classes among 268 mixed-sex newlywed couples in China based on two couple-level features - the absolute level of sexual satisfaction and synchrony over time - and then compare these classes on subsequent ratings of marital instability. Four distinct trajectory patterns were found: a stable high class, a wives low and simultaneous deterioration class, a husbands low decrease-wives high stable class, and a wives high decrease-husbands high stable class. Couples in the stable high class reported lower levels of marital instability at two-year follow-up compared to couples in the other classes, suggesting that high sexual satisfaction and synchrony is beneficial for couples' marital relationships. These results provide further evidence challenging the inevitability of sexual satisfaction declines and have important implications for interventions aiming to enhance couples' sexual relationship.

Does income moderate basic relationship processes?

Objective

This study explores whether household income moderates the predictive association from adaptive processes (positive and negative interactions and commitment), enduring vulnerabilities (psychological distress), and stressors (financial strain) to future relationship satisfaction?

Background

Theory and research have long conceptualized socioeconomic status as a predictor of couple relations, but recent work questions whether socioeconomic status may moderate basic couple relationship processes.

Method

This study used data from a U.S. national sample of 927 adults aged 18-34 years in a cohabiting (marital or nonmarital) different-sex partnership (66% female; 22% non-White; 47% earned a high school diploma or GED as their highest education credential) surveyed five times at 4-to 6-month intervals. A series of latent curve models with structured residuals were used to examine between- and within-person associations.

Results

Robust between-persons associations emerged consistent with prior literature (e.g., those with more positive and less negative interactions, higher commitment, lower psychological distress, and less financial strain reported higher relationship satisfaction). One robust longitudinal association emerged at the within-person level: higher than typical negative interactions predicted intraindividual decreases in future relationship satisfaction. Within-person associations were more evident in the cross-section: at times when positive interactions and commitment were higher than one's own average and negative interactions and psychological distress were lower than average, relationship satisfaction was also higher than average. Income did not moderate any links with future relationship satisfaction.

Conclusion

Results suggest that basic longitudinal processes in relationships operate consistently across income level.

Romantic Duration, Relationship Quality, and Attachment Insecurity among Dating Couples

For many young adults today dating is not taken as a path to marriage, but as a relationship to be considered on its own terms with a beginning, middle, and end. Yet, research has not kept pace as most studies that look at relationships over time focus on marriages. In the present study, we look at individual differences and normative patterns of dating relationship quality over time. We tested a path model of associations between relationship duration, attachment insecurity, and four relationship quality domains (sexual frequency, commitment, satisfaction, and companionship) among a large sample of dating young adults (N = 1345). Based on a conceptual model of romantic relationship development, results supported expectations that dating trajectories are curvilinear, with unique patterns of accent, peak, and decent for each relationship domain. Dating duration also moderated the relationship between dating quality and attachment insecurity with anxious attachment becoming a more salient predictor of lower satisfaction and lower commitment in long-term versus short-term relationships. A quadratic interaction with sexual frequency indicated that insecurity predicted less sexual activity in new relationships, more activity among relationships between two and four years, but then less again in longer-term relationships. Findings suggest patterns of stability and change in dating relationships during emerging adulthood that complement those observed from the marriage literature.

A randomized controlled trial of a 5-year marriage checkup booster session for a subsample of responder couples

This study examined maintenance and booster effects of a brief couple intervention, the Marriage Checkup (MC), across 5 years. A subsample of 63 couples who benefitted from two previous MCs (responder couples), were randomly assigned to a third MC or control. Before randomization (at 4-years-9-months), the responder sample had maintained small to medium effects on two measures of relationship functioning. After randomization, we found no significant between-group effects. Yet, within-group analyses revealed that while control couples showed flat trajectories in all outcomes after the 4-year-9-months baseline, couples receiving a third MC (at Year 5) reported small to medium improvements in three measures of relationship functioning and maintained follow-up effect in one measure. Findings indicate that couples who initially improved from the MC can maintain some of their improvements over long periods. The potential of boosting such improvements with recurrent MCs is a relevant target for further investigation in larger samples.

When the Partner's Reality Bites: Associations Between Self- and Partner Ratings of Psychopathic Traits, Relationship Quality and Conflict Tactics

The present study examined associations of self- and partner-reported psychopathic traits, as well as the level of agreement between these reports (perceptual accuracy), with relationship quality, and the moderating role of violent and non-violent conflict tactics. Participants were 259 heterosexual couples from the community. Results indicated that, despite moderate convergence between self- and partner-reports, the female partners tended to underreport the levels of psychopathic traits in their male partner. Relationship quality was negatively associated with partner-reported and, albeit to a lesser extent, self-reported psychopathic traits. Contrary to expectations, perceptual accuracy was barely associated with relationship quality. Whereas no evidence was found for the moderating role of aggressive conflict tactics, non-violent negotiation seemed to buffer the effect of psychopathic traits on relationship quality. The study highlights the importance of considering the partner's perceptions as well as constructive conflict tactics when examining psychopathic traits in intimate relationships.

So happy together … Examining the association between relationship happiness, socio-economic status, and family transitions in the UK

The increases in cohabitation and in childbearing within cohabitation raise questions about who marries. Most studies have found that childbearing within cohabitation is associated with disadvantage; here, we examine the role of relationship happiness and whether it helps to explain this association. Using the UK Household Longitudinal Study (2009-17), our competing risk hazard models follow respondents as they transition: (1) from cohabitation into marriage or childbearing; and (2) from marriage or cohabitation into childbearing. We find that marriage risks are highest among individuals who are happiest with their relationship. On average, the association between relationship quality and childbearing operates through marriage: the happiest individuals marry, and those who marry have children. While higher socio-economic status is weakly associated with marriage, conception, and separation, the associations do not differ by relationship happiness. The findings indicate that overall, relationship happiness appears to be most salient for transitions into marriage.

Concurrent randomized control trials of the 1-year efficacy of two couple relationship education programs: ELEVATE and Couples Connecting Mindfully

A long-standing university-community partnership used a longitudinal randomized control trial to implement and evaluate two couple relationship education (CRE) curricula, ELEVATE and Couples Connecting Mindfully (CCM), among an economically and racially diverse population of adult couples. Married and non-married couples (n = 929 couples) completed baseline surveys and were randomly assigned to either one of the two program groups or to the control group by implementation site. Follow-up surveys were collected at 2 months, 6 months, and 1 year after baseline. Using an intent-to-treat approach, growth curve modeling comparisons of trajectories indicated program effects at 1 year post-baseline in key outcome areas. Both the ELEVATE and the CCM group reported significant gains in couple relationship skills, couple quality, and family harmony over time compared to the control group that experienced either no change or declines. Further, the ELEVATE group also demonstrated positive program effects on measures of mental health and sleep quality. An assessment of the central premise of CRE indicated that the immediate post-program improvements in couple relationship skills predicted later couple quality for both program groups. This study indicates that both ELEVATE and CCM can be considered evidence-based CRE programs for use with a broad population of couples.

Relationship quality and support for family policy during the COVID-19 pandemic

Objective

We examined how relationship satisfaction changed during the coronavirus (COVID-19) pandemic, as well as how relationship satisfaction related to public policy support.

Background

Conservation of resources (COR) theory suggests that societal-level stressors (such as a global pandemic) threaten familial and individual resources, straining couple relationships. Relationship satisfaction is in turn linked with important individual, familial, and societal outcomes, necessitating research on how COVID-19 impacted this facet of relationships.

Method

Drawing from an international project on COVID-19 and family life, participants included 734 married and cohabiting American parents of children under 18 years of age.

Results

Findings revealed relationship satisfaction declined moderately compared to retrospective reports of relationship satisfaction prior to the pandemic. This decline was more precipitous for White individuals, women, parents less involved in their children's lives, and those reporting higher levels of depressive symptoms. We also found that higher relationship satisfaction was associated with higher levels of support for family policy, particularly for men. At higher levels of relationship satisfaction, men and women had similarly high levels of support for family policy, while at lower levels, women's support for family policy was significantly higher.

Conclusion

The COVID-19 pandemic likely amplified facets of social inequality, which is especially concerning when considering the large socioeconomic gaps prior to the pandemic.

Implications

Therapists, researchers, and policy makers should examine how relationship satisfaction may have changed during the pandemic because relationship satisfaction is linked to child and adult well-being and relationship dissolution. Further, the link between relationship satisfaction and support for family policy deserves further scrutiny.

Motivational Interdependence in Couple Relationships

This article presents an integrative conceptual model of motivational interdependence in couples, the MIC model. Based on theoretical tenets in motivation psychology, personality psychology, and research on interpersonal perception, the MIC model postulates that two partners' motive dispositions fundamentally interact in shaping their individual motivation and behavior. On a functional level, a partner's motivated behavior is conceptualized as an environmental cue that can contribute to an actor's motive expression and satisfaction. However, the partner's motivated behavior is considered to gain this motivational relevance only via the actor's subjective perception. Multilevel analyses of an extensive experience sampling study on partner-related communal motivation (N = up to 60,803 surveys from 508 individuals nested in 258 couples) supported the MIC model. Participants, particularly those with strong communal motive dispositions, behaved more communally at moments when they perceived their partners to behave more communally. In addition, participants experienced momentary boosts in satisfaction when they behaved more communally and, at the same time, perceived their partners' behavior as similarly communal. Broader implications of the MIC model for research on romantic relationships are discussed.

Sexual Minority Stressors and Intimate Partner Violence Among Same-Sex Couples: Commitment as a Resource

Accumulating evidence has been found for the associations from sexual minority stressors to intimate partner violence (IPV) among same-sex couples. Yet key gaps still exist, including the rare utilization of couple dyadic data, the understudied moderating and mediating mechanisms, and the few studies conducted during the transitional period of same-sex marriage legalization. To address these gaps, we used cross-sectional, dyadic data collected from 144 US same-sex couples during the 2014-2015 national campaign for the legalization of same-sex marriage. Guided by the systemic transactional model (STM), we examined associations from sexual minority stressors (including both internalized homophobia and discrimination) to same-sex IPV and tested whether commitment moderated or mediated these associations. Overall, we found evidence supporting the STM: (1) High internalized homophobia and discrimination were related to high prevalence and/or frequency of IPV perpetration; (2) high commitment attenuated positive associations between high discrimination and high prevalence and/or frequency of IPV perpetration; and (3) high internalized homophobia was related to low commitment, which in turn was related to high prevalence and/or frequency of IPV perpetration. Collectively, our study identified commitment as both a moderator and mediator in associations from sexual minority stressors to same-sex IPV. Further, the roles of commitment (i.e., moderator or mediator) depend on whether the focal sexual minority stressors are distal and more intermittent (i.e., heterosexist discrimination) or proximal and more constant (i.e., internalized homophobia).

Factors related to the quality and stability of partner relationships after traumatic brain injury: A systematic literature review

OBJECTIVE

The latest literature review on partner relationships following traumatic brain injury (TBI), conducted a decade ago, discussed solely quantitative work and noted significant knowledge gaps. The current review updates and expands on this work by providing an overview of the current state of knowledge on factors related to relationship quality and stability following TBI.

DATA SOURCES

CINAHL, Embase, MEDLINE, Psychology and Behavioral Sciences Collection, APA PsycINFO, and PubMed were searched on April 23, 2020, for literature on factors associated with 1)relationship quality and 2)relationship stability following TBI.

STUDY SELECTION

English quantitative and qualitative studies investigating factors associated with relationship quality and/or stability following TBI were included. Two reviewers independently assessed eligibility. If consensus was not reached, a third reviewer's conclusion was decisive. Forty-three studies were included.

DATA EXTRACTION

Information regarding study objectives and characteristics, participant demographics, (in)dependent variables, and main findings was extracted. Study quality was rated using the JBI Checklist for Analytical Cross Sectional Studies and/or the CASP Checklist for Qualitative Research. Both were performed by the lead reviewer and checked by the second reviewer.

DATA SYNTHESIS

Thirty-eight factors related to relationship quality and/or stability were identified, covering injury characteristics (e.g., severity), body functions (e.g., personality changes), activities (e.g., communication), participation (e.g., social dependence), environment (e.g., children), and personal factors (e.g., coping strategies).

CONCLUSIONS

Relationship quality and stability following TBI are found to be related to a multitude of factors, including newly identified factors such as personality changes and dependence. Future research may wish to quantitatively investigate factors thus far only identified in qualitative research, explore possible positive effects of TBI on relationships, study the experiences of same-sex couples, and include the perspectives of both partners with and without the injury.

Within-Couple Associations Between Communication and Relationship Satisfaction Over Time

Relationship science contends that the quality of couples' communication predicts relationship satisfaction over time. Most studies testing these links have examined between-person associations, yet couple dynamics are also theorized at the within-person level: For a given couple, worsened communication is presumed to predict deteriorations in future relationship satisfaction. We examined within-couple associations between satisfaction and communication in three longitudinal studies. Across studies, there were some lagged within-person links between deviations in negative communication to future changes in satisfaction (and vice versa). But the most robust finding was for concurrent within-person associations between negative communication and satisfaction: At times when couples experienced less negative communication than usual, they were also more satisfied with their relationship than was typical. Positive communication was rarely associated with relationship satisfaction at the within-person level. These findings indicate that within-person changes in negative communication primarily covary with, rather than predict, relationship satisfaction.

Social emotional ability development (SEAD): An integrated model of practical emotion-based competencies

Social emotional abilities (i.e., specific skills), defined as the set of cognitive abilities, emotion-based knowledge, and behavioral competencies (i.e., skill levels) that facilitate adaptively employing prosocial processes and behaviors (i.e., "actions"), such as emotional regulation and sympathetic and empathetic response behaviors, is contemporarily modeled and measured as emotional intelligence. This conceptualization can be problematic, however, as the two concepts are not the same and traditional methods of measuring emotional intelligence can have limited practical utility. The social emotional ability development (SEAD) theoretical model introduced in this treatise represents a pragmatic and simplified approach to the development of social emotional ability and competency as abstracted from constructs of emotional intelligence, social intelligence, and sociocultural learning theory. Further, the SEAD model reaches beyond the individual as the unit of analysis to explore, conceptualize, differentiate, investigate, and define the hierarchal, bi-directional, and contextual nature of the dimensions of social emotional ability within close relationships. Implications for how the SEAD model can be used by researchers, practitioners, educators, individuals, families, and couples across a broad spectrum of domains and interventions are discussed.

Helping couples achieve relationship success: A decade of progress in couple relationship education research and practice, 2010-2019

This article systematically reviewed 34 rigorous evaluation studies of couple relationship education (CRE) programs from 2010 to 2019 that met the criteria for Level 1 well-established interventions. Significant advances include reaching more diverse and disadvantaged target populations with positive intervention effects on a wider range of outcomes beyond relationship quality, including physical and mental health, coparenting, and even child well-being, and evidence that high-risk couples often benefit the most. In addition, considerable progress has been made delivering effective online CRE, increasing services to individuals rather than to couples, and giving greater attention to youth and young adults to teach them principles and skills that may help them form healthy relationships. Ongoing challenges include expanding our understanding of program moderators and change mechanisms, attending to emerging everyday issues facing couples (e.g., healthy breaking ups, long-distance relationships) and gaining increased institutional support for CRE.

Marital Strain and Support and Subjective Well-Being in Later Life: Ascribing a Role to Childhood Adversity

Objectives: We integrate the life course perspective with the stress-process model to offer a framework for how childhood conditions moderate the relationship between marital support/strain and subjective well-being in older adulthood for men and women. Methods: Drawing on longitudinal data from the National Social Life, Health, and Aging Project (NSHAP), we use a series of lagged dependent-variable models and stratify the sample by gender. Results: Our results suggest that the benefits associated with greater marital support are stronger for those that did not live with both parents in childhood for men. Women raised in families that experienced financial hardship reported lower subjective well-being in the context of marital strain. Conclusion: Adverse experiences in childhood can be scarring or foster resilience related to well-being in the context of strained or supportive marriages.

One Line of Sexual Decline? Growth Mixture Modeling for Midlife Sexual Satisfaction

Most research has shown that sexual satisfaction in long-term relationships tends to decline over time. Studies showing the average trajectory, however, are limited by only assessing one slope. With longitudinal data from the Flourishing Families Project, Marital Instability Dataset, and the Iowa Youth and Families Project, we utilized growth mixture modeling to assess what trajectories of sexual satisfaction exist in midlife marriages. In the three samples (one individual, two dyadic), we found clear evidence for heterogeneous sexual satisfaction trajectories, for both wives and husbands. Through the datasets, we found some trajectories did decline over time. We also found stably high, stably medium, stably low, and some trajectories that showed an increase in sexual satisfaction over time. Overall, trajectories were similar for wives and husbands, though some classes had one partner with variability while the other was stable, some classes had trajectories with wives having higher sexual satisfaction than husbands, and some classes had trajectories with husbands having higher sexual satisfaction than wives. Demographic variables were not strong distinguishers of these differing trajectories. Both marital satisfaction and perceived marital stability trajectories (based on sexual satisfaction classes) generally had similar patterns to sexual satisfaction trajectories, with a few exceptions. Both marital satisfaction and perceived marital stability were less likely to significantly change over time, have discrepancies between wives and husbands, and have either low marital satisfaction or high perceived marital instability, even if sexual satisfaction was low. These data can help couples recognize various possibilities for sexual satisfaction over time, perhaps helping them to avoid cultural myths of inevitably declining sexual satisfaction.

How both partners' individual differences, stress, and behavior predict change in relationship satisfaction: Extending the VSA model

We pooled data from 10 longitudinal studies of 1,104 married couples to test the Vulnerability-Stress-Adaptation (VSA) model of change in relationship satisfaction. Studies contained both spouses' self-reports of neuroticism, attachment anxiety, and attachment avoidance; observational measures of engagement and opposition during problem-solving discussions at baseline; and repeated reports of both spouses' stress and marital satisfaction over several years. Consistent with the VSA model, all three individual and partner qualities predicted changes in marital satisfaction that were mediated by observations of behavior and moderated by both partners' experiences with stress. In contrast to the VSA model, however, rather than accentuating the association between individual differences and behavior, both partners' stress moderated the strength, and even direction, of the association between behavior and changes in marital satisfaction over time. Taken together, these findings indicate that 1) qualities of both couple members shape their behavioral exchanges, 2) these behaviors explain how individuals and their partners' enduring qualities predict relationship satisfaction, and 3) stress experienced by both couple members strongly determines how enduring qualities and behavior predict changes in relationship satisfaction over time. The complex interplay among both partners' enduring qualities, stress, and behavior helps explain why studies may fail to document direct main effects of own and partner enduring qualities and behavior on changes in relationship satisfaction over time.

Marital quality over the life course and child well-being from childhood to early adolescence

Research on marital quality and child well-being is currently limited by its common use of geographically constrained, homogenous, and often cross-sectional (or at least temporally limited) samples. We build upon previous work showing multiple trajectories of marital quality and data from the National Longitudinal Survey of Youth-1979 (NLSY79) regarding mothers and their children (inclusive of ages 5-14). We examine how indicators of child well-being are linked to parental trajectories of marital quality (happiness, communication, and conflict). Results showed children whose parents had consistently poor marital quality over the life course exhibited more internalizing and externalizing problems, poorer health, lower quality home environments, and lower math and vocabulary scores than children of parents in consistently higher-quality marriages. Group differences remained stable over time for child health, home environment, and vocabulary scores. Group differences for internalizing problems declined over time, whereas group differences increased for externalizing problems and math scores. Initial advantages for females across nearly all indicators of child well-being tended to shrink over time, with boys often moving slightly ahead by mid adolescence. We discuss the implications of these findings in regard to children's development and well-being and suggest treating marriage as a monolithic construct betrays important variation within marriage itself.
