Neuroendocrine function, assessed in 90 couples during their first year of marriage (Time 1), was related to marital dissolution and satisfaction 10 years later. Compared to those who remained married, epinephrine levels of divorced couples were 34% higher during a Time 1 conflict discussion, 22% higher throughout the day, and both epinephrine and norepinephrine were 16% higher at night. Among couples who were still married, Time 1 conflict ACTH levels were twice as high among women whose…

Stress Hormone Changes and Marital Conflict: Spouses’ Relative Power Makes a Difference

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

The premarital communication roots of marital distress and divorce: the first five years of marriage.

It was found that all couples showed decreases innegative communication over time, but the nondistressed group declined significantly more than the distressed group in negative communication, suggesting they are handling negative emotions better.

Wives' and husbands' cortisol reactivity to proximal and distal dimensions of couple conflict.

Husbands appeared to be more physiologically reactive to the in-the-moment critical behaviors of wives during family conflicts involving children, whereas wives' responses to proximal conflict were related to previous and perhaps more chronic experiences of marital aggression.

The present findings highlight the need to understand the contextual factors that govern within-person and within-couple fluctuations in intimate violence.

Marriage, divorce, and the immune system.

Spousal similarities in health behaviors, gene expression, immune profiles and the gut microbiota offer new ways to consider the health advantages and risks of marriage and divorce, providing new perspectives on couples' interdependence, as well as new directions for research.

Longitudinal changes in spouses' HPA responses: Convergence in cortisol patterns during the early years of marriage.

It is suggested that spouses increasingly shape each other's cortisol responses as their relationship matures and increased similarity in acute cortisol levels during conflict may be associated with poorer relationship functioning.

Results reveal the differing ways marital disruption “gets under the skin” with widowhood associated with compromised inflammatory, metabolic, and cardiovascular functioning, and divorce with cardiovascular and neuroendocrine markers.

Anxiety and chronic couple relationship stress moderate adrenocortical response to couple interaction in expectant parents.

Negativity during couple interaction was associated with greater cortisol reactivity for men, but not women, and consistent results were found for the relation between low warmth in the couple interaction and both reactivity and recovery for men and women high in anxiety.

Marital conflict and endocrine function: are men really more physiologically affected than women?

Higher probabilities of husband's withdrawal in response to wife's negative behavior and higher frequencies of positive behaviors were associated with lower EPI and higher prolactin levels among wives, and Husbands' endocrine data were not associated with behavioral data.

Over the 1st 4 years of marriage, marital satisfaction and dissolution appear to be predicted by separate factors, suggesting that it may be necessary to focus on both factors in efforts to strengthen marriages and prevent divorce.

Marital processes predictive of later dissolution: behavior, physiology, and health.

A balance theory of marriage was used to generate 1 variable for dividing couples into regulated and nonregulated groups, and a "cascade" model of marital dissolution, which forms a Guttman-like scale, received preliminary support.
