Conflict and collaboration in middle-aged and older couples: II. Cardiovascular reactivity during marital interaction.

Marital strain confers risk of cardiovascular disease (CVD), perhaps though cardiovascular reactivity (CVR) to stressful marital interactions. CVR to marital stressors may differ between middle-age and older adults, and types of marital interactions that evoke CVR may also differ across these age groups, as relationship contexts and stressors differ with age. The authors examined cardiovascular responses to a marital conflict discussion and collaborative problem solving in 300 middle-aged and older married couples. Marital conflict evoked greater increases in blood pressure, cardiac output, and cardiac sympathetic activation than did collaboration. Older couples displayed smaller heart rate responses to conflict than did middle-aged couples but larger blood pressure responses to collaboration—especially in older men. These effects were maintained during a posttask recovery period. Women did not display greater CVR than men on any measure or in either interaction context, though they did display greater parasympathetic withdrawal. CVR to marital conflict could contribute to the association of marital strain with CVD for middle-aged and older men and women, but other age-related marital contexts (e.g., collaboration among older couples) may also contribute to this mechanism.

Conflict and love: Predicting newlywed marital outcomes from two interaction contexts.

Research on marital interaction has focused primarily on couples in conflict contexts to understand better processes associated with concurrent and longitudinal outcomes such as marital stability and quality. Although this work has consistently revealed particular emotions (e.g., contempt) or behavioral sequences (e.g., demand/withdraw) predictive of later marital distress, it largely has neglected to take positive contexts into consideration. The present longitudinal study begins to address this gap in the literature by directly comparing newlywed behaviors from a conflict-resolution interaction with those from a love-paradigm interaction to predict relationship satisfaction and divorce proneness approximately 15 months later. Results showed that actor and partner negative (contempt) and positive (affection) emotions elicited in both positive (i.e., love) and negative (i.e., conflict) interaction contexts emerged as unique predictors of relationship quality and stability for both husbands and wives. Moreover, using a linear growth model, the temporal course of positive emotion during the love context, but not the conflict context, was predictive of later relationship satisfaction. Implications for future marital research and intervention are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Gender moderates the relationship between testosterone and marital interaction.

Higher testosterone levels are related to assertiveness and dominance. Given the relevance of those behavioral correlates to spouses' daily transactions, links between testosterone levels and marital interaction were explored among 92 newlywed couples. Marital problem-solving and social support transactions were assessed, and saliva was collected and assayed for testosterone. Whether marital behavior was related to husbands' and wives' testosterone levels was examined. The link between spouses' testosterone and their behavior was contingent on the partner's testosterone levels. Husbands exhibited more adaptive problem-solving behaviors and social support provision when husbands and wives were concordant for lower testosterone levels. In contrast, wives exhibited more adaptive support provision when spouses had discordant testosterone levels such that wives had higher levels and husbands had lower levels.

Appraisals of marital conflict and children's adjustment, health, and physiological reactivity.

Children's appraisals of marital conflict were examined as moderators and mediators of conflict and children's adjustment, physical health, and physiological reactivity. Mothers completed measures of marital conflict and children's adjustment and physical health, and elementary school children provided information on their parents' marital conflict, appraisals of perceived threat and self-blame in relation to parents' conflicts, and their internalizing symptomatology. Children's heart rate, systolic and diastolic blood pressure, and skin conductance response and level were examined during both a baseline and an interadult argument. Higher levels of both self-blame and perceived threat functioned as robust vulnerability factors for children exposed to higher levels of marital conflict in relation to internalizing behaviors, health problems, and higher levels of cardiovascular reactivity to the argument. Further, a higher level of perceived threat was a vulnerability factor for externalizing problems associated with exposure to marital conflict.

Changes in children's appraisals of marital discord from childhood through adolescence.

The study examined how children's appraisals of marital conflict (threat and self-blame) changed across development, whether changes in exposure to marital conflict were associated with corresponding changes in appraisals, and whether the appraisal process was different for boys and girls. Data were collected on 112 families (224 children) at 4 time points. At each wave, children (mean ages ranged from 8 to 19) provided information on their appraisals of marital conflict, and parents provided information on children's exposure to marital conflict. Results indicated that appraisals of threat declined rapidly from childhood to adolescence and then declined less rapidly across adolescence; appraisals of self-blame showed little change over time. Second, changes in exposure to marital discord covaried with changes in threat over time, but not with changes in self-blame. Finally, boys experienced more self-blame than girls on average, and gender moderated the association between exposure to marital discord and threat. Results suggest that development, exposure to marital conflict, and gender are important in determining why some children appraise their parents' disputes negatively.

Children's responses to mothers' and fathers' emotionality and tactics in marital conflict in the home.

Addressing a gap in methodological approaches to the study of links between marital conflict and children, 51 couples were trained to complete home diary reports on everyday marital conflicts and children's responses. Parental negative emotionality and destructive conflict tactics related to children's insecure emotional and behavioral responses. Parental positive emotionality and constructive conflict tactics were linked with children's secure emotional responding. When parents' emotions and tactics were considered in the same model, negative emotionality was more consistently related to children's negative reactions than were destructive conflict tactics, whereas constructive conflict tactics were more consistently related to children's positive reactions than parents' positive emotionality. Differences in children's responding as a function of specific parental negative emotions (anger, sadness, fear) and parent gender were identified.

A process model of adolescents' triangulation into parents' marital conflict: The role of emotional reactivity.

[Correction Notice: An erratum for this article was reported in Vol 24(2) of Journal of Family Psychology (see record 2010-07067-002). In the article “A Process Model of Adolescents’ Triangulation Into Parents’ Marital Conflict: The Role of Emotional Reactivity” by Cheryl Buehler and Deborah P. Welsh (Journal of Family Psychology, 2009, Vol. 23, No. 2, pp. 167–180), the abstract contains an error. The sample size for the study was 416 rather than 426.] This study examined adolescents' emotional reactivity to parents' marital conflict as a mediator of the association between triangulation and adolescents' internalizing problems in a sample of 2-parent families (N = 426). Four waves of annual, multiple-informant data were analyzed (youth ages 11–15 years). The authors used structural equation modeling and found that triangulation was associated with increases in adolescents' internalizing problems, controlling for marital hostility and adolescent externalizing problems. There also was an indirect pathway from triangulation to internalizing problems across time through youths' emotional reactivity. Moderating analyses indicated that the 2nd half of the pathway, the association between emotional reactivity and increased internalizing problems, characterized youth with lower levels of hopefulness and attachment to parents. The findings help detail why triangulation is a risk factor for adolescents' development and which youth will profit most from interventions focused on emotional regulation.

Matters of the variable heart: Respiratory sinus arrhythmia response to marital interaction and associations with marital quality.

Maintenance of relationship quality requires self-regulation of emotion and social behavior, and women often display greater effort in this regard than do men. Furthermore, such efforts can deplete the limited capacity for self-regulation. In recent models of self-regulation, resting level of respiratory sinus arrhythmia, quantified as high-frequency heart rate variability (HF-HRV), is an indicator of self-regulatory capacity, whereas transient increases in HF-HRV reflect self-regulatory effort. To test these hypotheses in marriage, 114 young couples completed measures of marital quality and a positive, neutral, or negative initial marital task, preceded and followed by resting baseline assessments of HF-HRV. Couples then discussed a current marital disagreement. Resting HF-HRV was correlated with marital quality, suggesting that capacity for self-regulation is associated with adaptive functioning in close relationships. For women but not men, the negative initial task produced a decrease in resting HF-HRV. This effect was mediated by the husbands' negative affect response to the task and their ratings of wives as controlling and directive. When the subsequent disagreement discussion followed the negative initial task, women displayed increased HF-HRV during the discussion but a decrease when it followed the neutral or positive task. The valence of the initial task had no effect on men's HF-HRV during disagreement. Negative marital interactions can reduce women's resting HF-HRV, with potentially adverse health consequences. Women's reduced health benefit from marriage might reflect the depleting effects on self-regulatory capacity of their greater efforts to manage relationship quality.

Positive and negative characteristics of marital interaction and their association with marital satisfaction in middle-aged and older couples.

The study examined age differences in positive (e.g., warm) and negative (e.g., hostile) characteristics of marital interactions between middle-aged and older couples and whether these characteristics were differentially associated with marital satisfaction by age. Spouses' perception of partners' positive and negative behavior during marital interaction was assessed in general and following disagreement and collaborative tasks. Trained observers coded spouses' positive and negative behavior during interactions. Older individuals reported higher marital satisfaction and perceived their spouse's behavior as less negative in general and more positive across all contexts than middle-aged individuals. Spouses' perceptions of their partners' positive and negative behavior independently predicted marital satisfaction for both age groups across contexts. Perceptions of partners' negative behavior in general and of both positive and negative behavior in the disagreement task were more closely associated with marital satisfaction for older spouses than for middle-aged spouses. Results point to the importance of positive and negative characteristics in marital functioning across age cohorts and indicate that such characteristics may be context dependent. Findings suggest that, in some contexts, both positive and negative characteristics are more salient for older adults. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age-related differences in ambulatory blood pressure during daily stress: Evidence for greater blood pressure reactivity with age.

Prior research on age and emotions has found that older adults may show better physiological regulation to stressful stimuli than do younger adults. However, the stress reactivity literature has shown that age is associated with higher cardiovascular reactivity to laboratory stress (J. R. Jennings et al., 1997). The authors investigated these conflicting findings further by examining daily ambulatory blood pressure in 428 middle-aged to older adults. Consistent with the age and reactivity literature, relatively old individuals showed significantly greater increases in ambulatory diastolic blood pressure compared with younger individuals when dealing with daily stressors. However, results also revealed that relatively old individuals reported less of an increase in negative affect during daily stress compared with their younger counterparts. The results of this study are consistent with the age-related increase in cardiovascular risk but highlight the complex links between stress and different facets of the aging process.

Depressive symptoms in early marriage: Predictions from relationship confidence and negative marital interaction.

The authors proposed a model of depressive symptoms in early marriage in which relationship confidence, defined as perceived couple-level efficacy to manage conflicts and maintain a healthy relationship, mediates the effect of negative marital interactions on depressive symptoms. The model was tested in a sample of 139 couples assessed prior to marriage and 1 year later. As predicted, relationship confidence demonstrated simple negative associations with negative marital interaction and depressive symptoms for all participants. Longitudinal path analyses supported the mediational model for women only. In women but not men, negative marital interaction indirectly had an impact on depressive symptoms through the mediator of relationship confidence. Findings suggest that relationship confidence may be important to understanding links between marital distress and depressive symptoms, especially in women.

Blood pressure reactivity and cognitive function in the Baltimore Longitudinal Study of Aging.

Objective: Several blood pressure indexes of autonomic dysregulation, including stress-induced blood pressure responses (i.e., reactivity), have been associated previously with stroke, silent cerebrovascular disease, and decreased cognitive function. Design: The authors examined the cross-sectional relations among systolic blood pressure (SBP) and diastolic blood pressure (DBP) reactivity and cognitive function in a sample of stroke- and dementia-free older adults (n = 73, 53% male, 72% Caucasian, mean age = 70.14 years) from the Baltimore Longitudinal Study of Aging. Main Outcome Measures: Age, education, baseline, and reactive blood pressure levels were regressed on cognitive test scores measuring the domains of attention, learning and memory, verbal functions/language skills, and perceptuo-motor speed. A Bonferroni correction was employed and results significant at the standard p     

Discrimination and unfair treatment: Relationship to cardiovascular reactivity among African American and European American women.

This study examined the relationship of cardiovascular reactivity to both interpersonal mistreatment and discrimination in a community-based sample of African American and European American women (N?=?363) in midlife. Subtle mistreatment related positively to diastolic blood pressure (DBP) reactivity for African American participants but not their European American counterparts. Moreover, among the African American participants, those who attributed mistreatment to racial discrimination exhibited greater average DBP reactivity. In particular, these women demonstrated greater DBP reactivity to the speech task, which bore similarities to an encounter with racial prejudice but not to a nonsocial mirror tracing task. These findings are consistent with the hypothesis that racial discrimination is a chronic stressor that can negatively impact the cardiovascular health of African Americans through pathogenic processes associated with physiologic reactivity.

Links between physical fitness and cardiovascular reactivity and recovery to psychological stressors: A meta-analysis.

A meta-analysis of published studies with adult human participants was conducted to evaluate whether physical fitness attenuates cardiovascular reactivity and improves recovery from acute psychological stressors. Thirty-three studies met selection criteria; 18 were included in recovery analyses. Effect sizes and moderator influences were calculated by using meta-analysis software. A fixed effects model was fit initially; however, between-studies heterogeneity could not be explained even after inclusion of moderators. Therefore, to account for residual heterogeneity, a random effects model was estimated. Under this model, fit individuals showed significantly attenuated heart rate and systolic blood pressure reactivity and a trend toward attenuated diastolic blood pressure reactivity. Fit individuals also showed faster heart rate recovery, but there were no significant differences in systolic blood pressure or diastolic blood pressure recovery. No significant moderators emerged. Results have important implications for elucidating mechanisms underlying effects of fitness on cardiovascular disease and suggest that fitness may be an important confound in studies of stress reactivity.

Prospective associations from family-of-origin interactions to adult marital interactions and relationship adjustment.

To test the social learning-based hypothesis that marital conflict resolution patterns are learned in the family of origin, longitudinal, observational data were used to assess prospective associations between family conflict interaction patterns during adolescence and offspring's later marital conflict interaction patterns. At age 14 years, 47 participants completed an observed family conflict resolution task with their parents. In a subsequent assessment 17 years later, the participants completed measures of marital adjustment and an observed marital conflict interaction task with their spouse. As predicted, levels of hostility and positive engagement expressed by parents and adolescents during family interactions were prospectively linked with levels of hostility and positive engagement expressed by offspring and their spouses during marital interactions. Family-of-origin hostility was a particularly robust predictor of marital interaction behaviors; it predicted later marital hostility and negatively predicted positive engagement, controlling for psychopathology and family-of-origin positive engagement. For men, family-of-origin hostility also predicted poorer marital adjustment, an effect that was mediated through hostility in marital interactions. These findings suggest a long-lasting influence of family communication patterns, particularly hostility, on offspring's intimate communication and relationship functioning.

Conflict and collaboration in middle-aged and older couples: I. Age differences in agency and communion during marital interaction.

Prior theory and research regarding age differences in marital interaction suggest that older couples display and experience more positivity and less negativity than middle-aged couples. However, studies of overt behavior in older couples are relatively rare and have emphasized disagreement, neglecting other important contexts for older couples such as collaboration during everyday problem solving. Further, the affiliation or communion dimension of social interaction (i.e., warmth vs. hostility) is commonly assessed but not the control or agency dimension (e.g., dominance vs. submissiveness). The present study examined affect, cognitive appraisals, and overt behavior during disagreement (i.e., discussing a current conflict) and collaboration (i.e., planning errands) in 300 middle-aged and older married couples. Older couples reported less negative affect during disagreement and rated spouses as warmer than did middle-aged couples. However, these effects were eliminated when older couples’ greater marital satisfaction was controlled. For observed behavior, older couples displayed little evidence of greater positivity and reduced negativity—especially women. During collaboration, older couples displayed a unique blend of warmth and control, suggesting a greater focus on emotional and social concerns during problem solving.

Blood lead (Pb) levels: A potential environmental mechanism explaining the relation between socioeconomic status and cardiovascular reactivity in children.

Objective: A number of studies have shown an association between socioeconomic status (SES) and cardiovascular reactivity to acute stress. In addition, the authors recently reported that higher early childhood blood lead (Pb) levels are associated with significantly greater total peripheral (vascular) resistance (TPR) responses to acute stress. It is not known whether the SES-TPR association is mediated by underlying differences in blood lead levels. Design: Participants were 9.5-year-old children (N = 122) with established early childhood blood lead levels. Main Outcome Measures: Family SES was measured using the Hollingshead Index, blood lead levels were abstracted from pediatrician and state records, and children's cardiovascular responses to acute stressors were measured in the laboratory with impedance cardiography and an automated blood pressure monitor. Results: Lower family SES was shown to be associated with significantly higher blood lead levels as well as significantly heightened systolic blood pressure, diastolic blood pressure, and TPR responses to acute stress tasks. A mediational analysis confirmed that Pb was a significant mediator of the SES-TPR reactivity association; some evidence also suggested moderation. Conclusion: These results suggest the importance of considering the chemical environment as well as social and psychological environment when evaluating cardiovascular effects of low SES.

Do behavioral responses mediate or moderate the relation between cardiovascular reactivity to stress and parental history of hypertension?

To examine whether differences in behavioral responses to stress mediated or moderated the relation between cardiovascular response to stress and parental history of hypertension, 64 healthy undergraduates--16 men with hypertensive parents (PH+), 16 men without hypertensive parents (PH-), 16 PH+ women, and 16 PH- women--participated in a mental arithmetic task, mirror tracing task, and 2 interpersonal role plays. PH+ participants exhibited higher resting heart rates than PH - participants and higher resting systolic blood pressures (SBPs) than PH- women. PH+ participants exhibited greater SBP responses to tasks and engaged in more negative verbal and nonverbal behavior across tasks than PH- counterparts. Differences in behavioral responding neither mediated nor moderated the observed relation between parental history status and SBP response to stress.

Cognitive word use during marital conflict and increases in proinflammatory cytokines.

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-α (TNF-α). 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-α 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.
