Close relationships have the potential to fundamentally alter relationship partners’ self-concepts and, consequently, can impact individuals’ mental health. One type of relationship-induced self-concept change is self-expansion, which describes the cognitive reorganization of the self that can occur when individuals include aspects of their partner into the self, or when they share novel and challenging activities together. In the current research, we hypothesized that greater self-expansion would be associated with fewer depression symptoms. In support of this hypothesis, across four studies using cross-sectional, dyadic, daily diary, and longitudinal methodologies, we found that self-expansion was negatively associated with depression symptoms. This association was robust and remained a significant predictor of depression symptoms when controlling for demographic factors (gender, age, relationship length; Studies 1–4) and known risk factors of depression (dysfunctional attitudes, major life stressors, self-concept clarity; Study 2). Moreover, individuals’ self-expansion negatively predicted depression symptoms at the daily level (Study 3) and longitudinally over 9 months (Study 4). These results are the first to show the link between self-expansion and depression symptoms, suggesting that self-expansion may have robust benefits for individuals, beyond improving relationship dynamics.

Individuals hold implicit beliefs about the nature of romantic relationships. Growth beliefs are characterized by thoughts that romantic relationships can be cultivated over time, whereas destiny beliefs are characterized by thoughts that relationships are either meant to be or not. In the current research, we propose that individuals who hold strong growth beliefs (but not destiny beliefs) should be more likely to experience self-expansion, as these individuals are oriented toward relationship cultivation. In turn, this increase in self-expansion should promote greater relationship quality and maintenance. Across three studies (two cross-sectional and one longitudinal) that sampled from varying populations and relationship types, we found evidence that self-expansion mediates the association between growth beliefs (but not destiny beliefs) and satisfaction, commitment, accommodation, and dissolution consideration. These data provide insights into the mechanisms by which implicit theories influence relationship functioning and establish implicit theories as an individual-level antecedent to the self-expansion experience.

Studies have established that grown children’s problems affect parental well-being, but a dearth of research has addressed daily interactions and biological systems that may underlie these associations. This study examined whether parents have different types of daily interactions with adult children who have problems and whether those interactions are associated with variations in parents’ diurnal cortisol rhythms. Middle-aged parents (n = 197) reported their interactions with adult children for seven consecutive days and provided saliva, analyzed for cortisol, three times a day (wake, 30 minutes after wake, bedtime) for four of those days. Parents were more likely to report negative encounters but not less likely to report positive interactions or contact with adult children who suffered from problems. Interactions with adult children who had physical-emotional problems had more immediate same day associations with cortisol whereas interactions with adult children who had lifestyle-behavioral problems had more delayed, or next day associations with cortisol. Daily interactions and their associations with the hypothalamic-pituitary-adrenal-axis may be important mechanisms by which adult children with problems negatively affect parental well-being.

Romantic love has received significant theoretical and empirical attention from the perspectives of evolutionary psychology and traditional social psychology. Although their respective advancements on love have often occurred in isolation, there exists great overlap between the ideas presented by each discipline. In this chapter, we discuss this overlap and the likely benefits derived by bridging these disciplines more concertedly. We first discuss social psychological approaches to the study of love. We then shift focus to evolutionary psychological approaches, which build on social psychological research by emphasizing possible functions for the existence and experience of love. We conclude by suggesting other topics of relationship functioning that have been much investigated by traditional psychological approaches but have not been explored systematically through the lens of evolutionary psychology. It is our belief that there is significant value in exposing mainstream evolutionary psychologists to relevant research in the relationship science domain more generally and vice versa. It is this type of cross-talk that will be most advantageous for spurring mutually beneficial collaborations that will likely provide the greatest advances in our understanding of romantic love.

Individuals convicted of committing domestic violence are often court mandated to attend a Batterer Intervention Program (BIP). Evidence of the effectiveness of these programs, however, is inconclusive largely because of the diversity in approaches used by BIPs. In a pre-test/post-test design, the current study assessed outcomes associated with one specific BIP: a counseling-based, non-punitive psychoeducational program designed to treat both male and female domestic violence offenders. A sample of 149 clients completed a comprehensive survey both prior to and upon completion of the BIP. Participation in this BIP fostered attitudes known to be associated with nonviolence, including perceptions of accountability, anger management, indications of safety planning, and reported desire for change. Additionally, self-reported levels of psychological and physical violence decreased from pre- to post-treatment. Theoretical and therapeutic implications for BIPs are discussed.

In this review we argue that relatively recent evolutionary adaptations that are relational or psychological in nature might refocus, dampen, or otherwise shape hormonal processes related to evolutionarily “older” behaviors. We focus on the steroid hormones testosterone and estradiol and discuss a) their associations with “older relational processes” such as mate competition, dominance and nurturance, and b) the ways in which “newer relational processes” such as commitment and attachment relate to these hormones in the context of intimate relationships. We propose that these new relational processes might influence hormones in a manner that enables short-term mating relationships to be transformed into long-term romantic pair-bonds that may be unique to humans.

The purpose of this paper is to extend to the field of relationship science, recent discussions and suggested changes in open research practises. We demonstrate different ways that greater transparency of the research process in our field will accelerate scientific progress by increasing accuracy of reported research findings. Importantly, we make concrete recommendations for how relationship researchers can transition to greater disclosure of research practices in a manner that is sensitive to the unique design features of methodologies employed by relationship scientists. We discuss how to implement these recommendations for four different research designs regularly used in relationship research and practical limitations regarding implementing our recommendations and provide potential solutions to these problems.

We assessed the impact of thinking of a current romantic partner on acute blood glucose responses and positive affect over a short period of time. Participants in romantic relationships were randomly assigned to reflect on their partner, an opposite-sex friend, or their morning routine. Blood glucose levels were assessed prior to reflection, as well as at 10 and 25 min postreflection. Results revealed that individuals in the routine and friend conditions exhibited a decline in glucose over time, whereas individuals in the partner condition did not exhibit this decline (rather, a slight increase) in glucose over time. Reported positive affect following reflection was positively associated with increases in glucose, but only for individuals who reflected on their partner, suggesting this physiological response reflects eustress. These findings add to the literature on eustress in relationships and have implications for relationship processes.

The identification of relationship-relevant individual differences is central to elucidating how relationship experiences differentially impact individuals' health. To this end, we highlight the utility of studying the influence of individual differences on physiological outcomes (e.g., cortisol reactivity and recovery) in the context of normative relationship transitions. We argue that relationship transitions, such as falling in love and the process of committing to marry one's partner, amplify the influence of individual differences on relationship processes and, by extension, on physiological outcomes. Two such individual differences are highlighted-namely, relationship-focused processing and dependence-and suggestions for future work are provided.

Although evidence suggests that attachment anxiety may increase risk for health problems, the mechanisms underlying these effects are not well understood. In the current study, married couples ( N = 85) provided saliva samples over 3 days and blood samples on two occasions. Participants with higher attachment anxiety produced more cortisol and had fewer numbers of CD3+ T cells, CD45+ T cells, CD3+CD4+ helper T cells, and CD3+CD8+ cytotoxic T cells than participants with lower attachment anxiety. Higher cortisol levels were also related to fewer numbers of CD3+, CD45+, CD3+CD4+, and CD3+CD8+ cells, which is consistent with research showing that cortisol alters the cellular immune response. These data suggest that attachment anxiety may have physiological costs, and they provide a glimpse into the pathways through which social relationships affect health. The current study also extends attachment theory in an important new direction by demonstrating the utility of a psychoneuroimmunological approach to the study of attachment anxiety, stress, and health.

We examined the interplay between husbands’ and wives’ positive and negative nonsexual interpersonal behaviors, frequency of sexual intercourse, sexual satisfaction, and feelings of marital satisfaction. To do this, we conducted an in-depth face-to-face interview and completed a series of telephone diaries with 105 couples during their second, third, and fourteenth years of marriage. Consistent with the argument that women’s sexual response is tied to intimacy (Basson, 2000), multilevel analyses revealed that husbands’ positive interpersonal behaviors directed toward their wives—but not wives’ positivity nor spouses’ negative behaviors (regardless of gender)— predicted the frequency with which couples engaged in intercourse. The frequency of sexual intercourse and interpersonal negativity predicted both husbands’ and wives’ sexual satisfaction ; wives’ positive behaviors were also tied to husbands’ sexual satisfaction. When spouses’ interpersonal behaviors, frequency of sexual intercourse, and sexual satisfaction were considered in tandem, all but the frequency of sexual intercourse were associated with marital satisfaction. When it comes to feelings of marital satisfaction, therefore, a satisfying sex life and a warm interpersonal climate appear to matter more than does a greater frequency of sexual intercourse. Collectively, these findings shed much-needed light on the interplay between the nonsexual interpersonal climate of marriage and spouses’ sexual relationships.

The neuropeptide vasopressin has traditionally been associated with vasoconstriction and water reabsorption by the kidneys. However, data from experimental animal studies also implicate vasopressin in social bonding processes. Preliminary work suggests that vasopressin also plays a role in social behaviors in humans. The goal of this cross-sectional study was to evaluate associations among plasma vasopressin and self-reported interpersonal functioning in a sample of married couples. During a 24-hour admission to a hospital-based research unit, 37 couples completed measures of interpersonal functioning and provided blood samples for neuropeptide analyses. Results showed that vasopressin was associated with markers of interpersonal functioning, but not with general psychological distress. Specifically, greater plasma vasopressin levels were related to a larger social network, fewer negative marital interactions, less attachment avoidance, more attachment security, and marginally greater spousal social support. These results indicate that vasopressin is likely implicated in different relationship maintenance processes in humans.

Participant sex and a theorized correlate of biological sex, relational interdependence, were tested as relative predictors of the extent to which daters 1) missed and 2) used emotional support to cope when geographically separated from their dating partners. One hundred twenty-four daters completed multiple measures of missing and coping during their colleges' winter breaks. Results from regression analyses indicated that levels of missing and seeking emotional support differed as a function of biological sex. Further, relational interdependence was reliably associated with missing and seeking emotional support in theoretically consistent ways. Mediation analyses highlighted the importance of considering relational interdependence or other individual differences that covary with biological sex when studying close relationship phenomena.

We summarize the large body of research conducted over the previous 30 years on the link between interpersonal conflict and physiological outcomes, with a focus on implications for health. Specifically, we review evidence that conflict in close, romantic relationships affects internal bodily processes, including cardiovascular, endocrine, and immune function, as well as objective health indicators. We focus on studies that have utilized standardized, laboratory-based conflict discussions, as we believe this methodology provides the clearest picture of how conflict affects health. It is our hope that this general overview serves as a useful introduction to the state of the field.

This special issue on “mind–body connections in personal relationships” brings together 8 empirical contributions by researchers from a wide range of disciplinary backgrounds. The objectives for this issue were threefold: (a) to highlight research being conducted by close relationships researchers, (b) to foster disciplinary cross-pollination, and (c) to emphasize the interdisciplinary nature of the research in this domain. The quality of the submissions received for this special issue ensured that all of these objectives were met. The primary goal for this introduction to the special issue was to briefly outline how close relationships scholars are in prime position to contribute to a holistic understanding of the mechanisms underlying the reciprocal association between close relationships and physical/physiological functioning.

Working from the perspective of interdependence theory and models of relationship maintenance, this study examined the functional role of missing a romantic partner during a brief geographic separation. Eighty-eight undergraduate students involved in romantic relationships completed a measure of commitment prior to separation, and measures of missing a romantic partner, relationship maintenance, and physical infidelity during their winter break. Commitment was associated with participants’ self-reports of missing their romantic partners. Further, commitment predicted participants’ use of relationship maintenance strategies (i.e., positivity, openness, and assurances) and physical infidelity during the separation. These associations were mediated by how much participants missed their romantic partners. Findings are discussed in terms of interdependence theory and the growing literature on geographic distance between relationship partners.

Marital stress has been associated with immune dysregulation, including increased production of interleukin-6 (IL-6). Attachment style, one’s expectations about the availability and responsiveness of others in intimate relationships, appears to influence physiological stress reactivity and thus could influence inflammatory responses to marital conflict. Thirty-five couples were invited for two 24-hour admissions to a hospital research unit. The first visit included a structured social support interaction, while the second visit comprised the discussion of a marital disagreement. A mixed effect within-subject repeated measure model indicated that attachment avoidance significantly influenced IL-6 production during the conflict visit but not during the social support visit. Individuals with higher attachment avoidance had on average an 11% increase in total IL-6 production during the conflict visit as compared to the social support visit, while individuals with lower attachment avoidance had, on average, a 6% decrease in IL-6 production during the conflict visit as compared to the social support visit. Furthermore, greater attachment avoidance was associated with a higher frequency of negative behaviors and a lower frequency of positive behaviors during the marital interaction, providing a mechanism by which attachment avoidance may influence inflammatory responses to marital conflict. In sum, these results suggest that attachment avoidance modulates marital behavior and stress-induced immune dysregulation.

OBJECTIVE: To examine the effects of social support role (i.e., recipient versus provider) and experimentally manipulated closeness on men's and women's cortisol responses during an acute stress paradigm. METHODS: We manipulated psychological closeness (high versus low) between 50 same-sex stranger pairs and subsequently randomly assigned individuals to either prepare a speech (i.e., support recipient) or provide support to the speech presenter (i.e., support provider). RESULTS: When receiving support, cortisol responses of men in the high closeness condition increased over time relative to a) men in the low closeness condition and b) women in the high closeness condition. Cortisol responses of female support recipients did not differ as a function of condition. For support providers, whereas both men's and women's cortisol declined throughout the procedure, the decline for men was steeper than the decline for women. CONCLUSIONS: With few exceptions, psychological closeness, sex, and social support role interacted in theoretically consistent ways and each significantly contributed to the pattern of cortisol responses observed in men and women during a standardized acute stress paradigm. This work expands the growing literature on potential mechanisms underlying the social support-health link. Further, the employed methodology highlights the utility of borrowing established paradigms from the close relationships literature to help illuminate specific interpersonal characteristics that might affect social support dynamics in naturally existing relationships and at the same time control for extraneous variables.

We assessed the impact of an individual difference variable, relationship-focused thinking, on women's acute salivary cortisol responses during and after a guided imagery task. Specifically, 29 healthy women, all of whom were experiencing high levels of passionate love, but varied on levels of relationship-focused thinking, were assigned to one of two experimental conditions: a partner reflection condition or a cross-sex friend reflection condition. Results indicated that women experiencing passionate love evidenced increased cortisol levels when asked to reflect on their romantic partner and relationship relative to women asked to reflect on a cross-sex friendship, but this difference was particularly pronounced and relatively long-lasting for those women characterized by a high amount of relationship-focused thinking. Our study significantly expands extant work on the passionate love-cortisol link by isolating the impact of a specific psychological variable, relationship-focused thinking, on the physiological experience of falling in love. We believe our work highlights the advances that can be made when established work in the close relationships and neuroendocrine fields are integrated.

Nonmarital couples' salivary cortisol responses during a likelihood of marriage discussion were assessed. Sixty-eight couple members (34 couples) in the United States independently indicated the extent to which they had experience thinking about and talking about marriage to their current partners (i.e., marriage novelty). Couples subsequently jointly graphed their chance of marriage to each other over the course of their relationship histories. Increased levels of marriage novelty predicted heightened cortisol reactivity to the joint discussion relative to cortisol responses of couple members for whom the idea of marriage was less novel. These results highlight the impact simply discussing transitions can have on individuals' physiological responses, and add to the expanding literature concerning the link between nonmarital romances and biological outcomes.

Objective: To examine whether greater cognitive engagement during a marital conflict discussion, as evidenced by use of words that suggest thinking and meaning-making, results in attenuated proinflammatory cytokine increases to stress and wounding. Design: Husbands and wives (N 84 individuals) were observed during two separate 24-hr visits: each visit included a wounding procedure, which was followed by a nonconflictive marital discussion (first visit) and a conflictive marital discussion (second visit). Main Outcome Measures: Serum proinflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor- (TNF-). Results: Individuals who used more cognitive processing words during the conflict discussion (but not the nonconflictive discussion) showed smaller increases in serum IL-6 and TNF- over 24 hours; they also had lower levels of both cytokines 24 hours after baseline controlling for demographics, hostility, depressed mood, positive and negative interactions, and marital quality. Effects of word use were not mediated by ruminative thoughts after conflict. Although both men and women benefited from their own cognitive engagement, only husbands’ IL-6 patterns were affected by spouses’ engagement. Conclusion: In accord with research demonstrating the value of cognitive processing in emotional disclosure, this research suggests that productive communication patterns may help mitigate the adverse effects of relationship conflict on inflammatory dysregulation.

In this study, a prototype analysis of romantic missing was conducted. College-age participants in the United States generated features of missing a partner (Study 1) and rated their centrality (Study 2). In a reaction time task, participants made category judgments for central features more quickly than for noncentral features (Study 3). In recognition and recall tasks, central features were more salient in participants’ memory, and participants evaluated individuals experiencing central features in vignettes as missing their partners more (Study 4). A prototypebased measure of missing administered to individuals in long-distance relationships (Study 5) correlated with commitment and attachment dimensions but only weakly with loneliness. Finally, level of missing differed based on whether individuals were in a geographically distant (vs. proximal) relationships (Study 6).

Two recent studies (C. R. Agnew, T. J. Loving, & S. M. Drigotas, 2001; T. K. MacDonald & M. Ross, 1999) investigated the relative ability of outsiders’ (network members) and daters’ perceptions of the daters’ romance to predict relationship fate. Careful analysis of these studies suggests that the types of network members asked and what is asked significantly impact the prognostic ability of outsiders’ perceptions. The current research replicates and extends this literature and highlights the challenges posed when collecting outsiders’ perspectives of their friends’ relationships. Daters and 2 friends (1 female, 1 male) were asked to provide their perceptions of the dating relationship on 2 indexes: a direct prediction of the likelihood that the relationship would last 6 months and an overall qualitative assessment of the dater’s commitment. Results highlight the need for researchers to carefully attend to the instruments and samples employed when obtaining multiple perspectives of the same dating relationship.

We investigated the impact of relative marital power on 72 newlywed couples’ endocrinological responses to marital conflict. Marital power was determined by comparing spouses’ reports of dependent love for one another. Less powerful spouses displayed elevated adrenocorticotropic hormone (ACTH) responses to a conflict discussion. Shared power appeared to have a beneficial effect on wives’ but not husbands’ ACTH responses. Spouses’ cortisol levels declined over time, except for wives who were less powerful and for husbands who shared power with their wives. Conflict behaviors did not differ as a function of this marital power index. These data suggest that relative levels of general emotional power in relationships may play an important role in spouses’ physiological responses to marital conflict.

We investigated linkages between spousal support satisfaction and affective, cortisol, and blood pressure responses to conflict in two samples, 85 newlyweds and 31 older couples, married an average of 42 years. Couples were admitted to a hospital research unit and provided self-reports regarding the support received from their spouses. After a baseline period, couples engaged in a 30-min conflict discussion during which time blood was drawn for cortisol assessment. After the conflict, newlyweds' blood pressure was measured. Among newlywed wives, greater spousal support satisfaction was associated with smaller changes in negative affect and cortisol responses to conflict. Notably, newlywed wives and husbands demonstrated lower blood pressure after conflict when spousal support satisfaction was higher. In contrast, older husbands (but not wives) exhibited greater cortisol responses when spousal support satisfaction was lower. These relationships provide a window on mechanisms linking marriage and health for men and women across the life span.

The Attentional Focus Model (Karau & Kelly, 1992) predicts that time pressure should lead group members to focus on a restricted range of task-relevant cues and to adopt task completion as their major interaction objective. Although this prediction has been supported in several studies (e.g., Karau & Kelly, 1992; Kelly, Jackson, & Hutson-Comeaux, 1997; Kelly & Karau, 1999; Parks & Cowlin, 1995), the exact processes that underlie information restriction have not been specified. We propose that two processes are involved. Specifically, the restriction of information may occur because time pressure affects the way in which information is initially encoded or attended to before a group enters its decision-making phase, or because group members filter out what they judge to be less important information during group discussion and decision making. We assessed both of these processes within a decision-making experiment where time pressure was manipulated prior to learning information that would be used to perform a task. Recall of information learned prior to group discussion did not differ by time pressure condition, arguing against an encoding process. In contrast, interaction data demonstrated information restriction by group members, arguing for a filtering process. Thought listings collected 1 min into the group discussion in some groups also supported a filtering process, as did questionnaire data. Implications of these findings for the Attentional Focus Model and for effective group decision making are discussed.

The purpose of this paper is to extend recent discussions and suggested changes in open research practises to the field of relationship science. We demonstrate different ways that greater transparency of the research process accelerates scientific progress in our field by increasing accuracy of reported research findings. Importantly, we make concrete recommendations for how relationship researchers can transition to greater disclosure of research practices in a manner that is sensitive to the unique design features of methodologies employed by relationship scientists. We discuss how to implement these recommendations for four different research designs regularly used in relationship research. We discuss practical limitations regarding implementing our recommendations and provide potential solutions to these problems.

Five studies were conducted to develop and validate a brief measure of socially desirable responding (SDR) for use in close relationships research, the Inventory of Desirable Responding in Relationships (IDRR). Specifically, a two-component measure of SDR was created to assess individuals' tendencies to: (i) deceive themselves, and (ii) deceive others regarding negative aspects of their close relationship. Study 1 employed exploratory factor analyses to isolate items that loaded on two factors, labeled Relationship Self-Deception (REL-SD) and Relationship Impression Management (REL-IM). Study 2 confirmed the factor structure obtained in Study 1 and provided evidence for a two-factor versus one-factor model of relationship SDR. Consistent with the hypotheses, Study 3 demonstrated that REL-IM scores are higher when generated in a public condition relative to an anonymous condition, whereas REL-SD scores remain unaffected by this manipulation. Consistent with the literature on the role of illusions in mental health, Study 4 demonstrated that REL-SD is associated with multiple indices of relationship health. Study 5 validated the scale on a sample of married adults and provided evidence of divergent validity. Limitations and future research directions are discussed.

This research focused on perceptions held by heterosexual couples' friendship network concerning the couple's relationship. In a three-wave longitudinal study, we examined (a) whether these perceptions were similar to the couple's views of the relationship, (b) whether they predicted current relationship state and future fate, and (c) how they compared with the couple's perceptions in predicting fate. Consistent with within-dyad idealization, results from a North American sample indicated that network perceptions of relationship state were significantly more negative than those held by a couple. Although both the couples' and the total networks' perceptions predicted fate, friends of the female couple member were particularly successful at predicting relationship dissolution. An examination of possible mechanisms whereby friends may come to possess particularly predictive perceptions supported the role of couple-disclosure in this process.

This paper reports the findings from two studies which examined the tendency of sexually-active college students to provide socially desirable (i.e., positively biased) responses to questions concerning condom use. The first study found that while female attitudes toward condom use and intentions to use a condom were not associated with social desirability, such attitudes and intentions were significantly related to two measures of impression management for males. The second study attempted to identify conditions under which the relationship between condom use responses and impression management might be attenuated. Specifically, we tested whether participants would report more negative attitudes toward using condoms, and weaker behavioral intentions, when questionnaire instructions emphasized (1) participant anonymity, (2) the scientific importance of obtaining accurate responses, or (3) a combination of these two instructional sets. Results suggest that, compared to a no-instruction control group, self-reported male attitude toward and intention regarding condom use become more negative when anonymity is stressed. Female responses were unaffected by any of the instruction sets compared to the control group. The two studies provide converging evidence that college males positively bias their responses to questions regarding condom use, and suggest the need for further research on the attenuation of such misrepresentation.

We assessed the impact of thinking of a current romantic partner on acute blood glucose responses and positive affect over a short period of time. Participants in romantic relationships were randomly assigned to reflect on their partner, an opposite-sex friend, or their morning routine. Blood glucose levels were assessed prior to reflection, as well as at 10 and 25 min postreflection. Results revealed that individuals in the routine and friend conditions exhibited a decline in glucose over time, whereas individuals in the partner condition did not exhibit this decline (rather, a slight increase) in glucose over time. Reported positive affect following reflection was positively associated with increases in glucose, but only for individuals who reflected on their partner, suggesting this physiological response reflects eustress. These findings add to the literature on eustress in relationships and have implications for relationship processes.

Given the importance of close relationships in all facets of human life, it is no surprise that research on relationship processes is multidisciplinary and divergent in methodology. Such diversity in the study of close relationships should allow for a more detailed and comprehensive understanding of relationship processes, but researchers in different fields have yet to integrate their findings into a deeper, more holistic model of close relationship functioning. This book brings together different perspectives on close relationships to explore how such relationships develop, function, and interact across a variety of contexts. Prominent scholars contribute theory and empirical research rooted in developmental, social, and cross-cultural psychology, as well as evolutionary science, individual differences, and psychophysiology. Both early and adult relationships are examined, along with parent-child relationships. This excellent resource will be well received by researchers and students in the social sciences who are interested in a broader, more collaborative approach to relationship science.

We examined how daters' levels of relationship dependence interact with men's and women's degree of accommodation during a likelihood of marriage discussion to predict cortisol levels at the conclusion of the discussion. Upon arriving at the laboratory, couple members were separated and asked to graph their perceived likelihood of one day marrying each other. Couples were reunited and instructed to create a joint graph depicting their agreed-upon chance of marriage. For the majority of couples, negotiating their likelihood of marriage required one or both partners to accommodate each other's presumed likelihood of marriage. Multilevel analyses revealed a significant Dependence × Accommodation × Sex interaction. For women who increased their likelihood of marriage, feelings of dependence predicted heightened levels of cortisol relative to baseline; we suggest such a response is indicative of eustress. Among men, those who accommodated by decreasing their likelihood of marriage experienced significantly lower levels of cortisol to the extent that they were less dependent on their partners. Discussion focuses on why men and women show different physiological reactions in response to seemingly favorable outcomes from a relationship discussion.

Animal studies have implicated oxytocin and vasopressin in social bonding, physiological stress responses, and wound healing. In humans, endogenous oxytocin and vasopressin levels covary with perceptions of relationship quality, marital behaviors, and physiological stress responses. To investigate relationships among marital behavior, oxytocin, vasopressin, and wound healing, and to determine the characteristics of individuals with the highest neuropeptide levels, 37 couples were admitted for a 24-h visit in a hospital research unit. After small blister wounds were created on their forearm, couples participated in a structured social support interaction task. Blister sites were monitored daily following discharge to assess wound repair speed. Blood samples were collected for oxytocin, vasopressin, and cytokine analyses. Higher oxytocin levels were associated with more positive communication behaviors during the structured interaction task. Furthermore, individuals in the upper oxytocin quartile healed blister wounds faster than participants in lower oxytocin quartiles. Higher vasopressin levels were related to fewer negative communication behaviors and greater tumor necrosis factor-alpha production. Moreover, women in the upper vasopressin quartile healed the experimental wounds faster than the remainder of the sample. These data confirm and extend prior evidence implicating oxytocin and vasopressin in couples' positive and negative communication behaviors, and also provide further evidence of their role in an important health outcome, wound healing.

We examined 31 older couples’ wife demand/husband withdraw communication patterns and cortisol responses to marital conflict. Regression analyses indicated that wife demand/husband withdraw sequences during conflict related to cortisol responses only for wives. Based on a mixed model that accounted for the interdependence of spouses’ perceptions of communication patterns and outcomes, older spouses who reported greater wife demand/husband withdraw patterns in their marriage had greater cortisol responses during a conflict discussion; actual demand-withdraw did not relate to cortisol responses in this model. Findings suggest that perceived communication patterns contribute to neuroendocrine responses to marital conflict, and implications for marriage and health research with older couples are discussed.

A growing body of research linking psychological and behavioral factors to the incidence and progression of cancer suggests that psychosocial factors may have an impact on some types of cancer [1–6]. In this paper, we suggest that it is through the impact these behavioral and psychological factors have on the cellular immune response, including natural killer (NK) cell function, that they may ultimately affect the occurrence and progression of certain tumors. Our discussion of this link begins with a brief overview of the evidence that psychoneuroimmunology (PNI) research with healthy individuals may be relevant to cancer. Next, to link extant PNI research findings with tumorigenesis, we draw upon two important PNI findings relating psychological distress to two important aspects of carcinogenesis: (i) poorer repair of damaged cellular DNA and (ii) modulation of apoptosis. Finally, we focus on the implications of intervention research in cancer patients for cancer progression and treatment. Before reviewing the evidence regarding stress-related immunological changes, it should be noted that one recurrent concern in the literature is the question of the significance of the immune system for cancer. Cancer is comprised of a heterogeneous group of diseases with multiple etiologies [1], and immunological involvement varies across different cancers. Those cancers that are induced by chemical carcinogens (e.g. lung cancer) may be less influenced by psychological, behavioral and immunological factors than cancers that are associated with a virus, such as Epstein–Barr Virus (EBV), which are immunogenic. Suppression of cellular immunity is associated with a higher incidence of certain types of tumors, particularly EBV-associated lymphoproliferative diseases in organ transplant patients, and Kaposi’s sarcoma and EBVassociated B-cell lymphoma in AIDS patients [7]. Additionally, some researchers have questioned whether stress-related immune changes are of either the type or the magnitude to influence tumor growth and metastases [3, 8]. While such issues are beyond the scope of this paper, compelling evidence exists for the role of cells, such as NK cells, in resisting the progression and metastatic spread of tumors once they have developed [7]. Stress and immune dysregulation

Although evidence suggests that attachment anxiety may increase risk for health problems, the mechanisms are not well understood. Married couples (N = 85, Mage = 38.67) provided saliva samples over three days and blood samples on two occasions. Participants with higher attachment anxiety produced more cortisol and had fewer numbers of CD45+ T cells, CD3+ T cells, CD3+CD4+ helper T cells, and CD3+CD8+ cytotoxic T cells than those with lower attachment anxiety. Higher cortisol was also related to fewer numbers of CD45+, CD3+, CD3+CD4+, and CD3+CD8+, which is mechanistically consistent with research showing that cortisol alters the cellular immune response. These data suggest that attachment anxiety may have physiological costs and provide a glimpse into the pathways through which social relationships impact health. The current study also extends attachment theory in an important new direction by utilizing a psychoneuroimmunological approach to the study of attachment anxiety, stress, and health.

In animal studies, the neuropeptides oxytocin and vasopressin have been implicated in social behaviors. In humans, plasma levels of oxytocin covary with perceptions of relationship quality, but little is known about the association between plasma vasopressin and social behaviors in humans. The goal of this study was to evaluate the relationships among plasma oxytocin and vasopressin and self-reported social functioning. Thirty-seven couples completed measures of social functioning and provided blood samples for neuropeptide analysis during a 24-hour admission to a hospital-based research unit. Higher plasma oxytocin was associated with less hostility among men, p = .001, but not women, p = .67. Across both men and women greater levels of vasopressin were associated with larger social networks, p = .05, less negative spousal interactions, p = .03, less attachment avoidance, p = .03, more attachment security p = .04, and marginally with greater spousal social support, p = .06. Overall, higher social functioning was associated with greater plasma vasopressin levels. This study provides evidence that plasma vasopressin levels have small, but significant associations with dimensions of social functioning in humans.
