Intranasal Oxytocin Increases Positive Communication and Reduces Cortisol Levels During Couple Conflict

BACKGROUND In nonhuman mammals, the neuropeptide oxytocin has repeatedly been shown to increase social approach behavior and pair bonding. In particular, central nervous oxytocin reduces behavioral and neuroendocrine responses to social stress and is suggested to mediate the rewarding aspects of attachment in highly social species. However, to date there have been no studies investigating the effects of central oxytocin mechanisms on behavior and physiology in human couple interaction. METHODS In a double-blind placebo-controlled design, 47 heterosexual couples (total n = 94) received oxytocin or placebo intranasally before a standard instructed couple conflict discussion in the laboratory. The conflict session was videotaped and coded for verbal and nonverbal interaction behavior (e.g., eye contact, nonverbal positive behavior, and self-disclosure). Salivary cortisol was repeatedly measured during the experiment. RESULTS Oxytocin significantly increased positive communication behavior in relation to negative behavior during the couple conflict discussion (F = 4.18, p = .047) and significantly reduced salivary cortisol levels after the conflict compared with placebo (F = 7.14, p = .011). CONCLUSIONS These results are in line with animal studies indicating that central oxytocin facilitates approach and pair bonding behavior. Our findings imply an involvement of oxytocin in couple interaction and close relationships in humans.

Effects of different kinds of couple interaction on cortisol and heart rate responses to stress in women

In animal studies, positive social interaction and physical contact play a preeminent role in the control of behavioral and neuroendocrine responses to stress. The aim of this study was to determine whether specific kinds of couple interaction reduce hypothalamic-pituitary-adrenal (HPA) and autonomic responses to psychosocial stress in women. Sixty-seven women, aged 20-37 years, who had been married or cohabiting with a male partner for at least 12 months at the time of the study, were exposed to a standardized psychosocial laboratory stressor (Trier Social Stress Test). Participants were randomly assigned to three study groups differing in the type of a 10-min period of social interaction with their partner prior to stress: n=25 with no partner interaction, n=22 with verbal social support, and n=20 with physical contact (standardized neck and shoulder massage). Salivary free cortisol levels, plasma levels of oxytocin, heart rate, and psychological responses to stress were compared among the three study groups. Women with positive physical partner contact before stress exhibited significantly lower cortisol and heart rate responses to stress but no different plasma oxytocin levels compared to women who received social support or no social interaction. Verbal social support alone was not associated with reduced stress responsiveness. Our results are in line with previous human studies indicating reduced responsiveness to verbal social support by a spouse in women. More importantly, these findings imply a direct protective effect of touch on stress-related neurobiological systems as a possible underlying mechanism of health beneficial effects of positive couple interaction.

The role of stress on close relationships and marital satisfaction.

Stress is a concept that has received increased attention in marital research during the last decade, showing that it plays an important role in understanding the quality and stability of close relationships. Evidence suggests that stress is a threat to marital satisfaction and its longevity. Research has been based upon theoretical models of stress in close relationships, specifically family stress models [e.g., Hill, R. (1958). Generic features of families under stress. Social Casework, 39, 139-150.; McCubbin, H. I., & Patterson, J. M. (1983). Family transitions: Adaptation to stress. In H. I. McCubbin & C. R. Figley (Eds.), Stress and the family: Coping with normative transitions (Vol. 2, pp. 5-25). New York: Brunner/Mazel] and couples stress models proposed by Karney, Story, and Bradbury [Karney, B. R., Story, L. B., & Bradbury, T. N. (2005). Marriages in context: Interactions between chronic an acute stress among newlyweds. In T. A. Revenson, K. Kayser, & G. Bodenmann (Eds.), Couples coping with stress: Emerging perspectives on dyadic coping (pp.13-32). American Psychological Association: Washington, D.C.] and Bodenmann [Bodenmann, G. (1995). A systemic-transactional conceptualization of stress and coping in couples. Swiss Journal of Psychology, 54, 34-49.; Bodenmann, G. (2005). Dyadic coping and its significant for marital functioning. In T. Revenson, K. Kayser, & G. Bodenmann (Eds.), Couples coping with stress: Emerging perspectives on dyadic coping (pp.33-50). American Psychological Association: Washington, D.C.]. In this review we: (1) examine the various theoretical models of stress, (2) analyze and summarize the typologies relating to stress models (internal versus external, major versus minor, acute versus chronic), and (3) summarize findings from stress research in couples that has practical significance and may inspire clinical work. Future directions in research and clincial significance are suggested.

The relationship between dyadic coping and marital quality: a 2-year longitudinal study

Previous studies have revealed that the ways couples deal with stress in their lives are significantly associated with their marital quality and overall marital functioning. However, there has been little empirical evidence linking dyadic coping with marital quality over time. This study addresses the relationship between dyadic coping and marital quality among 90 couples over a period of 2 years. The results reveal that dyadic coping was significantly associated with marital quality over 2 years. For women, both their own dyadic coping and that of their partner were significant predictors, whereas for men only their own dyadic coping was predictive. The results are discussed with regard to prevention of marital distress.

The efficacy of the Triple P-Positive Parenting Program in improving parenting and child behavior: a comparison with two other treatment conditions.

The aim of this randomized controlled trial was to evaluate the efficacy of an evidence-based parenting program (the Triple P-Positive Parenting Program), intending to improve parenting skills and childrens well-being. Parents participating in a Group Triple P program (n=50 couples) were compared with parents of a non-treated control group (n=50 couples) and parents participating in a marital distress prevention program (couples coping enhancement training (CCET)) (n=50 couples). The two major goals of this study were (a) to evaluate the efficacy of Triple P compared with the two other treatment conditions over a time-span of 1 year and (b) to answer the question whether this program that was developed in Australia is culturally accepted by Swiss parents. Results revealed that Triple P was effective with Swiss families. Mothers of the Triple P group showed significant improvements in parenting, parenting self-esteem, and a decrease in stressors related to parenting. Women trained in Triple P also reported significantly lower rates of childs misbehavior than women of the two other conditions. However, in men only a few significant results were found. Positive effects of the relationship training (CCET) were somewhat lower than those for the Triple P. These findings are further discussed.

Stress and Coping Among Stable-Satisfied, Stable-Distressed and Separated/Divorced Swiss Couples

Abstract This article presents a 5-year prospective longitudinal study exploring the effects of stress and individual and dyadic coping on relationship stability among couples in Switzerland. Stress and coping variables assessed at the beginning of the study (tl) were used as predictors for the relationship status five years later (i.e., stable-satisfied; stable-distressed; separated/divorced). At the time of first measurement, all three groups differed significantly in their stress and individual and dyadic coping profiles. On average, the stable-satisfied couples were characterized by a lower level of stress, practiced less dysfunctional individual coping strategies, and relied more frequently on interpersonal (dyadic) coping when dealing with stress. At the end of the five-year period, it was possible to classify couples with 62.1% accuracy into one of three groups-stable-satisfied, stable-distressed, or separated/divorced. On the basis of the predictor variables, 73.3% of the couples could be correctly classified as being either stable or unstable.

Associations among everyday stress, critical life events, and sexual problems

This study addresses the question of how stress is linked to sexual problems among women and men in close relationships. Psychological symptoms, relationship quality, internal daily stress (i.e., originating within the couple such as conflicts, worry for the partner), external daily stress (i.e., stress arising outside the couple such as job stress, stressful relatives, and so forth), and critical life events were examined with regard to their association with different sexual problems. The results support the hypotheses that (1) there is an incremental effect of stress on sexual problems after controlling for psychological symptoms and relationship quality, and that (2) it is primarily internal daily stress and in some cases critical life events rather than external daily stress that are related to sexual problems, particularly hypoactive sexual desire in women and men, sexual aversion in women, vaginismus in women, and premature ejaculation in men. Our findings indicate that the treatment of these sexual problems should address relationship issues and include a focus on helping individuals improve their stress management skills within their couple relationship.

Effects of relationship education on maintenance of couple relationship satisfaction

Couple relationship education (RE) is the provision of structured education intended to promote healthy couple relationships, and prevent future relationship distress. There is a well-replicated finding that 9-20 hours of curriculum-based RE produces short-term improvements in couple communication and relationship satisfaction, but that established finding does not test whether RE helps couples maintain high relationship satisfaction. The current paper summarizes 17 published studies evaluating RE that have follow up assessments of at least 1 year, of which 14 studies found RE helped maintenance of relationship satisfaction. Couples with elevations of modifiable risk factors benefit substantially from RE, while benefits for couples with low risk have not yet been reliably demonstrated. Couples with elevations on risk factors not readily modified by current forms of RE are likely to show little or no benefit. Future research needs to clarify the mediators of RE effects, and how those mediators are moderated by couple risk profiles.

Depression, Marital Satisfaction and Communication in Couples: Investigating Gender Differences

The correlation between depression and dysfunctional marital interaction is well documented, but only a few studies have examined gender-related differences in marital interaction patterns of couples with a depressed partner. In this paper we examined differences in observed marital communication in a sample of 62 Swiss couples presenting for treatment of depression. There were 16 maritally distressed couples with a depressed wife, 21 maritally nondistressed couples with a depressed wife, 18 maritally distressed couples with a depressed husband, and 7 maritally nondistressed couples with a depressed husband. Marital interaction behavior was found to depend on gender, depression, marital distress, as well as gender of the depressed partner. Our results suggest the need for a gender-sensitive model of the link between marital interaction and depression.

Stress, anger, and verbal aggression in intimate relationships: Moderating effects of individual and dyadic coping

Verbally aggressive exchanges between intimate partners are more likely during times of stress. Therefore, the present study examines (i) whether partners’ proneness to anger mediates the association between stress and verbal aggression and (ii) the degree to which individual and dyadic coping moderate associations among stress, anger, and aggression. Effective individual and dyadic coping reduces the effects of stress on aggression. Moreover, dyadic coping may attenuate associations between stress and both anger and verbal aggression. Individuals reporting adaptive and maladaptive coping typically differed in verbal aggression when stress was low, but not when stress was high. This is consistent with the notion that stressors govern strong negative emotion displayed in marriage. Implications of these findings for interventions that mitigate the effects of stress on relationships are discussed.
