Children's emotional and physiological responses to interadult angry behavior: the role of history of interparental hostility

The biobehavioral family model and the family relational assessment protocol: Map and GPS for family systems training

The Biobehavioral Family Model (BBFM) was developed and evolved as a heuristic research model to support the investigation of pathways by which family relational function impacts individual family member wellbeing and disorder. Recently, the BBFM and its related assessment approach, the Family Relational Process Assessment Protocol (FRAP), have emerged as tools for clinical practice and training. The BBFM model will be presented, along with definitions of the dimensions constructed in the model, and research evidence in support of the model. To illustrate how the BBFM and FRAP are used in training, instructions for conducting the FRAP will be presented. Then, transcripts from two contrasting families participating in one of the interaction tasks will illustrate how, in training, the FRAP is interpreted through the BBFM lens to illuminate how these patterns of family relationship impact the identified patient. Finally, three applications of this training approach will exemplify the use of the BBFM and FRAP in the context of a Child and Adolescent Psychiatry Fellowship, a Family Medicine Fellowship, and a Family Therapy Training Program in Istanbul, Turkey. Limitations and future directions for the application of the BBFM in the exploration of multicultural aspects of family function for clinical and training purposes will be discussed.

The Biobehavioral Family Model: An Evidence-Based Approach to Biopsychosocial Research, Residency Training, and Patient Care

Engel's biopsychosocial model, based in systems theory, assumes the reciprocal influence of biological, psychological, and social factors on one another and on mental and physical health. However, the model's application to scientific study is limited by its lack of specificity, thus constraining its implementation in training and healthcare environments. The Biobehavioral Family Model (BBFM) is one model that can facilitate specification and integration of biopsychosocial conceptualization and treatment of illness. The model identifies specific pathways by which family relationships (i.e., family emotional climate) impact disease activity, through psychobiological mechanisms (i.e., biobehavioral reactivity). Furthermore, it is capable of identifying positive and negative effects of family process in the same model, and can be applied across cultural contexts. The BBFM has been applied to the study of child health outcomes, including pediatric asthma, and adult health, including for underserved primary care patients, minoritized samples, and persons with chronic pain, for example. The BBFM also serves as a guide for training and clinical practice; two such applications are presented, including the use of the BBFM in family medicine residency and child and adolescent psychiatry fellowship programs. Specific teaching and clinical approaches derived from the BBFM are described in both contexts, including the use of didactic lecture, patient interview guides, assessment protocol, and family-oriented care. Future directions for the application of the BBFM include incorporating temporal dynamics and developmental trajectories in the model, extending testable theory of family and individual resilience, examining causes of health disparities, and developing family-based prevention and intervention efforts to ameliorate contributing factors to disease. Ultimately, research and successful applications of the BBFM could inform policy to improve the lives of families, and provide additional support for the value of a biopsychosocial approach to medicine.

Mindfulness Interventions to Reduce Impact of Interparental Conflict on Adolescents

Exposure to frequent, intense, and poorly resolved interparental conflict puts adolescents at risk for problems in many domains, including internalizing and externalizing problems, and stress physiological dysfunction. Existing intervention strategies to target these adolescents focus almost solely on improving marital dynamics, for example, through relationship education or couples therapy. However, interventions that aim to enhance marital communication require high levels of parental commitment and motivation for change, and may be expensive and time-consuming. In the current paper, we argue that it is essential to also apply intervention strategies that directly promote the regulatory capabilities of adolescents to improve outcomes for youth from high-conflict homes. Mindfulness, or present-moment, nonjudgemental awareness, is associated with myriad positive outcomes in adults (e.g., lower levels of depression and anxiety, and greater emotion regulation). We propose that mindfulness interventions are an ideal intervention strategy for adolescents from high conflict homes. Mindfulness interventions may target the mechanisms whereby destructive marital interaction impacts youth, by providing distance between experiences and evaluations, training regulation of attention, and enhancing self-compassion and nonjudgement, as well as by enhancing relationships. We also provide an example of a specific intervention model designed to increase mindfulness in youth, Learning to Breathe (L2B).

Salivary cortisol reactivity in preschoolers is associated with hair cortisol and behavioral problems

The interplay between children's cortisol reactivity to challenge and cumulative cortisol exposure is not well understood. Examining the role of cortisol reactivity in early childhood may elucidate biological mechanisms that contribute to children's chronic physiological stress and behavioral dysregulation. In a sample of 65 preschool-aged children, we examined the relation between children's salivary cortisol reactivity to challenging tasks and their hair cortisol concentration (HCC). While both are biomarkers of the hypothalamic-pituitary-adrenal (HPA) axis, salivary cortisol reactivity reflects an acute cortisol response to a stressor and HCC reflects cumulative cortisol exposure. In addition, we examined the relations of these stress biomarkers with internalizing and externalizing problems. Salivary cortisol reactivity was associated with higher HCC and with increased externalizing behaviors. Child HCC also was positively correlated with parent HCC. Results highlight the contributions of salivary cortisol reactivity to children's cumulative cortisol exposure, which may add to their biological risk for health problems later. The observed association between externalizing problems and salivary cortisol reactivity indicates concordances between dysregulated behavioral reactions and dysregulated cortisol responses to challenges. The finding that salivary cortisol reactivity to challenge in early childhood plays a role in children's cumulative cortisol exposure and behavioral development suggests pathways through which cortisol reactivity may influence long-term physical and mental health.

Adolescent Conflict Appraisals Moderate the Link Between Marital Conflict and Physiological Stress Reactivity

The goal of this study was to advance understanding of how adolescent conflict appraisals contribute uniquely, and in combination with interparental conflict behavior, to individual differences in adolescent physiological reactivity. Saliva samples were collected from 153 adolescents (52% female; ages 10-17 years) before and after the Trier Social Stress Test. Saliva was assayed for cortisol and alpha-amylase. Results revealed interactive effects between marital conflict and conflict appraisals. For youth who appraised parental conflict negatively (particularly as threatening), negative marital conflict predicted dampened reactivity; for youth who appraised parental conflict less negatively, negative marital conflict predicted heightened reactivity. These findings support the notion that the family context and youth appraisals of family relationships are linked with individual differences in biological sensitivity to context.

Associations between parents' marital functioning, maternal parenting quality, maternal emotion and child cortisol levels

Associations between family functioning and children's stress hormone levels are explored, by examining how aspects of the interparental relationship (parents' marital satisfaction and parent conflict styles), the mother—child relationship (maternal involvement and warmth) and maternal emotional functioning (depression, anxiety and self-esteem) relate to children's cortisol levels. Parents of 63 children (32 kindergarten-aged children, 31 adolescents) completed questionnaires regarding family and individual functioning, and children's salivary cortisol samples were collected on two consecutive weekdays at home immediately upon waking and at bedtime, such that wakeup, bedtime and average levels and the slope of their diurnal cortisol rhythms could be estimated. Higher marital functioning was significantly and independently associated with lower child cortisol levels (average levels and wakeup levels), while maternal parenting quality and emotional functioning were not significant when included in the same regression model. Associations between parents' marital functioning and children's bedtime cortisol levels and diurnal slopes were moderated by child age, with higher parent marital functioning being associated with a significantly greater lowering of bedtime levels and steeper diurnal slopes for kindergarten-aged children as compared to adolescents. Higher maternal parenting quality was found to be significantly related to steeper diurnal cortisol rhythms.

Childhood maltreatment and violence: mediation through psychiatric morbidity

Childhood maltreatment is associated with multiple adverse outcomes in adulthood including poor mental health and violence. We investigated direct and indirect pathways from childhood maltreatment to adult violence perpetration and the explanatory role of psychiatric morbidity. Analyses were based on a population survey of 2,928 young men 21-34 years in Great Britain in 2011, with boost surveys of black and minority ethnic groups and lower social grades. Respondents completed questionnaires measuring psychiatric diagnoses using standardized screening instruments, including antisocial personality disorder (ASPD), drug and alcohol dependence and psychosis. Maltreatment exposures included childhood physical abuse, neglect, witnessing domestic violence and being bullied. Adult violence outcomes included: any violence, violence toward strangers and intimate partners (IPV), victim injury and minor violence. Witnessing domestic violence showed the strongest risk for adult violence (AOR 2.70, 95% CI 2.00, 3.65) through a direct pathway, with psychotic symptoms and ASPD as partial mediators. Childhood physical abuse was associated with IPV (AOR 2.33, 95% CI 1.25, 4.35), mediated by ASPD and alcohol dependence. Neglect was associated with violence toward strangers (AOR 1.73, 95% CI 1.03, 2.91), mediated by ASPD. Prevention of violence in adulthood following childhood physical abuse and neglect requires treatment interventions for associated alcohol dependence, psychosis, and ASPD. However, witnessing family violence in childhood had strongest and direct effects on the pathway to adult violence, with important implications for primary prevention. In this context, prevention strategies should prioritize and focus on early childhood exposure to violence in the family home.

Relation between aggression exposure in adolescence and adult posttraumatic stress symptoms: Moderating role of the parasympathetic nervous system

The present study examines the impact of the parasympathetic nervous system (PNS), as measured by respiratory sinus arrhythmia (RSA), on the link between family aggression experienced during adolescence and posttraumatic stress symptoms during young adulthood. Participants completed retrospective self-report measures of interparental aggression and harsh parenting exposure during adolescence and measures of current posttraumatic stress symptoms. RSA indexed PNS activity. Among females, the three-way interaction between harsh parenting, interparental aggression, and resting RSA was significant in accounting for young adulthood PTSD symptoms. At higher values of resting RSA and higher levels of interparental aggression exposure, harsh parenting experienced during adolescence was positively associated with adulthood PTSD symptoms. Among males, adolescent aggression exposure and resting RSA did not significantly account for variation in adulthood PTSD symptoms. Thus, this study suggests that resting PNS activity may play an important role in the relationship between stressors during adolescence and later PTSD in females.

Poverty, household chaos, and interparental aggression predict children's ability to recognize and modulate negative emotions

The following prospective longitudinal study considers the ways that protracted exposure to verbal and physical aggression between parents may take a substantial toll on emotional adjustment for 1,025 children followed from 6 to 58 months of age. Exposure to chronic poverty from infancy to early childhood as well as multiple measures of household chaos were also included as predictors of children's ability to recognize and modulate negative emotions in order to disentangle the role of interparental conflict from the socioeconomic forces that sometimes accompany it. Analyses revealed that exposure to greater levels of interparental conflict, more chaos in the household, and a higher number of years in poverty can be empirically distinguished as key contributors to 58-month-olds' ability to recognize and modulate negative emotion. Implications for models of experiential canalization of emotional processes within the context of adversity are discussed.

The role of skin conductance level reactivity in the impact of children's exposure to interparental conflict on their attention performance

Previous research suggests that undermining of attention performance might be one decisive underlying mechanism in the link between marital conflict and children's academic maladjustment, but little is known about specific risk patterns in this regard. This study examines, in an experimental approach, the role of children's history of interparental discord and skin conductance level reactivity (SCLR) as moderators in the link between analogue marital conflict exposure and children's attention. The attention performance of 57 children, aged 11 to 13 years, was assessed prior to and immediately after a 1-min video exposure to either (a) a couple conflict or (b) a neutral condition. SCLR was measured continuously throughout the stimulus presentation. Results indicated that children's family background of interparental conflict and their physiological reactivity moderated the influence of the experimental stimulus on children's short-term attention performance. Lower SCLR served as a protective factor in children from high-conflict homes exposed to the couple conflict. The current study advances the body of knowledge in this field by identifying risk patterns for the development of attention problems in children in relation to marital conflict exposure.

Gender differences in emotion expression in children: a meta-analytic review

Emotion expression is an important feature of healthy child development that has been found to show gender differences. However, there has been no empirical review of the literature on gender and facial, vocal, and behavioral expressions of different types of emotions in children. The present study constitutes a comprehensive meta-analytic review of gender differences and moderators of differences in emotion expression from infancy through adolescence. We analyzed 555 effect sizes from 166 studies with a total of 21,709 participants. Significant but very small gender differences were found overall, with girls showing more positive emotions (g = -.08) and internalizing emotions (e.g., sadness, anxiety, sympathy; g = -.10) than boys, and boys showing more externalizing emotions (e.g., anger; g = .09) than girls. Notably, gender differences were moderated by age, interpersonal context, and task valence, underscoring the importance of contextual factors in gender differences. Gender differences in positive emotions were more pronounced with increasing age, with girls showing more positive emotions than boys in middle childhood (g = -.20) and adolescence (g = -.28). Boys showed more externalizing emotions than girls at toddler/preschool age (g = .17) and middle childhood (g = .13) and fewer externalizing emotions than girls in adolescence (g = -.27). Gender differences were less pronounced with parents and were more pronounced with unfamiliar adults (for positive emotions) and with peers/when alone (for externalizing emotions). Our findings of gender differences in emotion expression in specific contexts have important implications for gender differences in children's healthy and maladaptive development.

Family relationships and children's stress responses

In this chapter, the theoretical and empirical associations between family relationships and children's responses to stressors are reviewed. Family relationships explored are primarily dyadic, representing the emphasis of past empirical research; these include parent-parent, parent-child, and sibling relationships. However, in recognition of the more complicated and interconnected nature of family relationships, also reviewed are associations between the broader family context and children's stress responses. Multiple measures of stress responses are considered, including both physiological and emotional responses to and recovery from stressful experiences. Overall, the studies reviewed suggest that poor-quality family environments, including those characterized by low emotional support or high conflict, are associated with dysregulated stress responses throughout childhood and adolescence. In contrast, children and adolescents in families with high emotional support or low conflict seem to be protected from developing stress regulatory problems. Limitations in this body of research as well as directions for future research are discussed.

A polymorphism in the serotonin transporter gene moderates cardiovascular reactivity to psychosocial stress

OBJECTIVE

To examine whether a polymorphism (5-HTTLPR: serotonin transporter linked polymorphic region) in the promoter of the serotonin transporter gene (SLC6A4) moderates cardiovascular reactivity to social threat.

METHODS

Psychologically healthy young adults delivered a speech and performed mental arithmetic in one of three conditions: a) an evaluative audience condition that gave disapproving and negative nonverbal social signals (n = 59); b) an evaluative audience condition that provided supportive social signals (n = 60); or c) a no audience condition (n = 65). Heart rate (HR) and systolic and diastolic blood pressures (DBP) were measured before, during, and after the stress tasks to assess cardiovascular reactivity and recovery.

RESULTS

In the negative audience condition, there was a significant association between the 5-HTTLPR and systolic blood pressure, DBP, and HR reactivity. Individuals with the short/short genotype showed the greatest reactivity. The DBP and HR reactivity of short/short individuals in the negative audience condition was also greater than that of individuals with the short/short genotype in the no audience condition. These associations of the 5-HTLPR with HR reactivity were moderated by gender, being limited to females. With respect to cardiovascular recovery, short/short individuals in the negative audience condition exhibited impaired DBP recovery relative to other genotypes in the same condition, as well as short/short individuals in the no audience condition.

CONCLUSIONS

The 5-HTTLPR moderates cardiovascular reactivity to stress in a threatening evaluative social context, which suggests that the serotonin system may be involved in the processes by which stressful, conflict-ridden social environments affect risk for cardiovascular-related health outcomes.

Impacts of domestic violence on child growth and nutrition: a conceptual review of the pathways of influence

Domestic violence against women is a global problem, and young children are disproportionate witnesses. Children's exposure to domestic violence (CEDV) predicts poorer health and development, but its effects on nutrition and growth are understudied. We propose a conceptual framework for the pathways by which domestic violence against mothers may impair child growth and nutrition, prenatally and during the first 36 months of life. We synthesize literatures from multiple disciplines and critically review the evidence for each pathway. Our review exposes gaps in knowledge and opportunities for research. The framework also identifies interim strategies to mitigate the effects of CEDV on child growth and nutrition. Given the global burden of child malnutrition and its long-term effects on human-capital formation, improving child growth and nutrition may be another reason to prevent domestic violence and its cascading after-effects.

Interparental relationship dynamics and cardiac vagal functioning in infancy

This study examined associations between interparental relationship dynamics and vagus system functioning in infancy. The functioning of the vagus system, part of the parasympathetic nervous system, indexes emotional reactivity and regulation. Interparental avoidance and dyadic adjustment constitute the focus of this study in order to bring attention to relationship dynamics not subsumed under overt conflict. Infants' baseline vagal tone and change in vagal tone in response to a novel toy were assessed at 5 months in a sample of high-risk mother-infant dyads (n=77). Maternal report of interparental avoidance demonstrated an association with infants' baseline vagal tone, while interparental dyadic adjustment was associated with change in infants' vagal tone from baseline to the novel toy. Infant gender moderated these associations. Maternal sensitivity did not mediate interparental relationship dynamics and infants' vagal functioning. Results are discussed in the context of emotional security theory.

Domestic violence and longitudinal associations with children's physiological regulation abilities

The present study examined the impact of domestic violence (DV) on children's emotion regulation abilities measured via baseline vagal tone (VT). Specifically, the authors examined the relationship between DV exposure and children's regulatory functioning over time, investigating whether DV exposure was related to the trajectory of children's physiological regulatory abilities from the preschool period to middle childhood. Covariates, including marital dissatisfaction and conduct-problem status, along with potential gender differences, were examined. Though all children increased in baseline VT from Time 1 to Time 2, children exposed to DV displayed less increase in baseline VT over time as compared to nonexposed children. Results in terms of the long-term outcomes of DV on children and implications for interventions were taken into consideration and discussed in the article.

Father bonding and blood pressure in young adults from intact and divorced families

OBJECTIVE

The father-child relationship may uniquely affect offspring's physical and psychological health. Divorce may change the nature of the father-child bond and the long-term health consequences of paternal parenting behaviors. The current study investigated a possible biological pathway from father-child relationship quality to physical health outcomes in young adults.

METHODS

Cardiovascular stress reactivity to a lab-based challenge task and ambulatory blood pressure (ABP) were measured in young adults (mean age=20.1 years) from divorced (n=50) and intact, married (n=49) families. Participants completed self-report measures of paternal control and caring during childhood.

RESULTS

Higher perceived father control was associated with elevated BP reactivity to the task and higher ABP among participants from divorced families. Young adults from intact families who reported lower paternal caring demonstrated higher ABP.

CONCLUSIONS

The family context may provide an important backdrop for evaluating the long-term physiological consequences of fathers' parenting behaviors.

Methodological issues in assessing psychological adjustment in child witnesses of intimate partner violence

This review summarizes a growing number of methodological concerns emerging from research on child witnesses of intimate partner violence (IPV). A brief summary of various psychological, biological, and cognitive impairments associated with witnessing IPV is presented. Directions for future research in this area are explored with particular attention paid to experimental design. Advantages and disadvantages of retrospective, cross-sectional, and longitudinal designs are evaluated. Suggested improvements include the use of multiple informants, behavioral observations, and prospective, longitudinal assessment.

Testing the Biobehavioral Family Model in pediatric asthma: pathways of effect

This study uses a laboratory-based multiinformant, multimethod approach to test the hypothesis that a negative family emotional climate (NFEC) contributes to asthma disease severity by way of child depressive symptoms, and that parent-child relational insecurity mediates the effect. Children with asthma (n = 199; aged 7-17; 55% male) reported parental conflict, parent-child relational security, and depressive symptoms. Parent(s) reported demographics, asthma history, and symptoms. Asthma diagnosis was confirmed by clinical evaluation and pulmonary function tests, with disease severity rated by an asthma clinician according to NHLBI guidelines. Family interactions were evoked using the Family Process Assessment Protocol, and rated using the Iowa Family Interaction Rating Scales. Path analysis indicated a good fit of data to the hypothesized model (chi2[1] = .11, p =.74, NFI = .99, RMSEA = .00). Observed NFEC predicted child depression (beta = .19, p < .01), which predicted asthma disease severity beta = .23, p < .01). Relational security inversely predicted depressive symptoms (p = -.40, p < .001), and was not a mediator as predicted, but rather an independent contributor. The findings are consistent with the Biobehavioral Family Model, which suggests a psychobiologic influence of specific family relational processes on asthma disease severity by way of child depressive symptoms.

The role of child adrenocortical functioning in pathways between interparental conflict and child maladjustment

This study examined the interplay between interparental conflict and child cortisol reactivity to interparental conflict in predicting child maladjustment in a sample of 178 families and their kindergarten children. Consistent with the allostatic load hypothesis (McEwen & Stellar, 1993), results indicated that interparental conflict was indirectly related to child maladjustment through its association with individual differences in child cortisol reactivity. Analyses indicated that the multimethod assessment of interparental conflict was associated with lower levels of child cortisol reactivity to a simulated phone conflict between parents. Diminished cortisol reactivity, in turn, predicted increases in parental reports of child externalizing symptoms over a 2-year period. Associations between interparental conflict, child cortisol reactivity, and child externalizing symptoms remained robust even after demographic factors and other family processes were taken into account.

Marital conflict and risk for child maladjustment over time: skin conductance level reactivity as a vulnerability factor

Skin conductance level reactivity (SCLR) was examined as a longitudinal mediator and moderator of relations between parental marital conflict and psychopathology among children and young adolescents. Participants were 157 boys and girls (M age at T1 = 9.31 years; SD = 1.97); there was a 2-year lag between T1 and T2 assessments. At T1, participants' SCLR was assessed in response to lab challenges. Parents completed measures of aggressive marital conflict and child adjustment at T1 and T2. Supportive of moderation effects, T1 marital conflict interacted with T1 SCLR and gender in the prediction of changes in maladjustment. The link between marital conflict and increased internalizing and externalizing symptoms was stronger for girls with higher SCLR than girls with lower SCLR. Marital conflict predicted increased externalizing behaviors for boys with lower SCLR but not higher SCLR, although levels of externalizing behaviors were similar among boys with lower and higher SCLR especially at higher levels of marital conflict. Findings build on the literature by illustrating the importance of examinations of both family risk and youth biological vulnerability for the prediction of psychopathology.

Exoneration reduces adult conflict's effects on preschoolers' cognitions, behavioral distress, and physiology

In this experiment, the authors investigated the influence of exoneration from blame on children's overt behavioral distress and physiological reactivity following the presentation of overheard adult conflict. The participants were 48 children (48-71 months of age) and their mothers. Through random assignment, the authors presented 16 children with statements that exonerated them from an overheard disagreement between two adults, did not address 16 during a similar disagreement, and presented 16 with a neutral discussion of difficulties. Exonerated children responded with less distress than did nonaddressed children, but did not differ from children presented the neutral discussion, except for overt behavioral distress. Nonaddressed children most often blamed themselves for the argument. Exonerating statements may protect children from attributional error and resultant physiological arousal during adult conflict.

A comparison of family functioning, life and marital satisfaction, and mental health of women in polygamous and monogamous marriages

BACKGROUND

A considerable body of research concludes that the polygamous family structure has an impact on children's and wives' psychological, social and family functioning.

AIMS

The present study is among the first to consider within the same ethno-racial community such essential factors as family functioning, life satisfaction, marital satisfaction and mental health functioning among women who are in polygamous marriages and women who are in monogamous marriages.

METHOD

A sample of 352 Bedouin-Arab women participated in this study: 235 (67%) were in a monogamous marriage and 117 (33%) were in a polygamous marriage.

RESULTS

Findings reveal differences between women in polygamous and monogamous marriages. Women in polygamous marriages showed significantly higher psychological distress, and higher levels of somatisation, phobia and other psychological problems. They also had significantly more problems in family functioning, marital relationships and life satisfaction.

CONCLUSION

The article calls on public policy and social service personnel to increase public awareness of the significance of polygamous family structures for women's wellbeing.

The psychobiology of children exposed to marital violence

We examined the psychological and physiological functioning of a community sample of children exposed to marital violence, comparing them to a clinical comparison group without marital violence exposure. Results replicated past findings of elevated levels of trauma symptomatology in this population. Further, children exposed to marital violence differed significantly from comparison children with respect to sympathetic nervous system functioning and hypothalamic-pituitary-adrenal (HPA) axis functioning. Specifically, elevations were seen in heart rate and salivary cortisol levels, but not in orthostatic challenge response or blood pressure. These results indicate that children exposed to marital violence have a different physiological presentation than controls and may be physiologically "traumatized" by virtue of marital violence exposure.

Emotional security and cognitive appraisals mediate the relationship between parents' marital conflict and adjustment in older adolescents

In this study, the authors evaluated a model of the effects of parental conflict witnessed in childhood on psychosocial adjustment in 175 college students. Using this model, which integrated the cognitive-contextual framework (J. H. Grych & F. D. Fincham, 1990) and the emotional-security hypothesis (P. T. Davies & E. M. Cummings, 1994), the authors proposed that both cognitive appraisal of parents' conflict and emotional security mediate the conflict-adjustment link in late adolescence. Furthermore, the authors proposed that cognitive appraisals are associated with emotional security. The results suggested that appraisals and security were both important mediators in the model but that they were not related to each other. Instead, there appeared to be parallel, yet separate, cognitive and emotional channels through which exposure to parental conflict in childhood can have detrimental effects on later adjustment.

What are the costs of marital conflict and dissolution to children's physical health?

Do parental marital conflict and dissolution influence the risk trajectory of children's physical health risk? This paper reviews evidence addressing this question in the context of understanding how early environmental adversities may trigger a succession of risks that lead to poor health in childhood and greater risk for chronic health problems in adulthood. We first review existing evidence linking marital conflict and dissolution to offspring's physical health outcomes. Next, we provide evidence supporting biopsychosocial pathways that may link marital conflict and dissolution with accelerated health risk trajectories across the lifespan. Specifically, we posit that consequential to the stresses associated with marital conflict and disruption, parenting practices are compromised, leading to offspring deficits in affective, behavioral, and cognitive domains. These deficits, in turn, are hypothesized to increase health risk through poor health behaviors and by altering physiological stress-response systems, including neuroendocrine, cardiovascular, and neurotransmitter functioning. On the basis of the available direct evidence and theoretically plausible pathways, it appears that there is a cost of marital conflict and disruption to children's health; however, more comprehensive investigations are needed to further elucidate this relationship. In the final section, we address limitations in the current literature and identify research that is needed to better evaluate the association between marital conflict and dissolution and children's physical health.

The relations of mothers' negative expressivity to children's experience and expression of negative emotion

Guided by the heuristic model proposed by Eisenberg et al. [Psychol. Inq. 9 (1998) 241], we examined the relations of mothers' reported and observed negative expressivity to children's (N = 159; 74 girls; M age = 7.67 years) experience and expression of emotion. Children's experience and/or expression of emotion in response to a distressing film were measured with facial, heart rate, and self-report measures. Children's heart rate and facial distress were modestly positively related. Children's facial distress was significantly positively related to mothers' reports of negative (dominant and submissive) expressivity; the positive relation between children's facial distress and mothers' observed negative expressivity approached the conventional level of significance. Moreover, mothers' observed negative expressivity was significantly negatively related to children's heart rate reactivity during the conflict film. The positive relation between children's reported distress and mothers' observed negative expressivity approached the conventional level of significance. Several possible explanations for the pattern of findings are discussed.

Children's physiological indices of empathy and their socioemotional adjustment: does caregivers' expressivity matter?

Relations of heart rate and skin conductance reactions to mildly evocative empathy-inducing slides with socioemotional functioning were examined for 154 children (mean age = 9 years, 5 months). In addition, maternal expressivity was tested as a moderator of these relations. Parents and teachers rated children's socioemotional functioning, and a behavioral measure of children's regulation was obtained. Boys who exhibited higher skin conductance and higher heart rate to slides depicting negative emotions were better regulated, less emotionally intense, and better adjusted than their peers. Furthermore, boys' regulation and adjustment were positively related to such physiological responding to negative slides if maternal negative expressivity was relatively low or moderate, but not high. Fewer findings were obtained for girls or for positive slides.

The effect of polygamous marital structure on behavioral, emotional, and academic adjustment in children: a comprehensive review of the literature

Polygamy represents expanded family structures that are based on marriages involving a husband with 2 or more wives. Interestingly, polygamy is legally and widely practiced in 850 societies across the globe. In the last 2 decades, polygamy has been the focus of a significant growth in public, political, and academic awareness. Indeed, several quantitative and qualitative research articles and theoretical papers have emerged during this period, particularly concerning the effects of this form of marital structure on behavioral, emotional, and academic adjustment of children. However, to date, no researcher has provided a summary of the extant literature. Thus, the purpose of this comprehensive literature review is to summarize findings and to discuss implications of empirical studies that have examined whether polygamous marital structures are beneficial or harmful to children in comparison with children raised in monogamous marital structures. This review includes a summary of the findings from all quantitative and qualitative studies in the extant literature that have examined the effect of polygamy on children's outcomes.

Witnessing interparental psychological aggression in childhood: implications for daily conflict in adult intimate relationships

We examined the consequences of witnessing interparental psychological aggression in childhood for daily conflict processes in adult intimate relationships. Both partners in 73 heterosexual couples provided daily diary reports of relationship conflict over a 28-day period. Partners' reports of witnessing mother-to-father and father-to-mother psychological aggression were used to predict exposure to daily relationship conflicts and reactivity to those conflicts (as reflected in end-of-day anger). Results showed no evidence of exposure effects: Witnessing interparental psychological aggression was unrelated to the number of conflict days reported by either partner. Reactivity effects emerged for males only, with father's aggression predicting increased reactivity and mother's aggression predicting the opposite. However, we found evidence of direct or unmediated effects of interparental conflict on daily anger for both males and females. Mirroring the reactivity pattern, the same-sex parent's psychological aggression predicted greater daily anger, whereas the opposite-sex parent's aggression predicted less daily anger. These effects emerged independently of Big Five measures of personality; moreover, Big Five measures did not predict outcomes independently of interparental aggression.

Predictors of children's cortisol activation during the transition to kindergarten

The purpose of the present study was to identify predictors of children's cortisol responses after the transition to kindergarten. Morning salivary cortisol was measured in 50 children 1 week before and 1 week after they began kindergarten. Children who experienced a greater degree of change between their preschool and kindergarten routines and who had infrequent preschool experiences exhibited the largest increases in morning cortisols after kindergarten entry. Children whose parents indicated that they would have an easier, rather than more difficult, time adapting to kindergarten also tended to be more reactive in their morning cortisol levels after kindergarten entry. Results provide new insight into experiential and individual-difference factors that predict children's physiological reactivity and self-regulation during times of transition and potential stress.

Interparental aggression and young children's representations of family relationships

Children's maternal, self, and marital representations were examined in 46 children 3 1/2 to 7 years old using the MacArthur Story Stem Battery. Children drawn from agencies serving battered women expressed fewer positive representations of their mothers and themselves, were more likely to portray interparental conflict as escalating, and were more avoidant and less coherent in their narratives about family interactions than children from a nonviolent community sample. Interparental aggression uniquely predicted representations of conflict escalation and avoidance after accounting for parent-child aggression, and the two types of aggression had additive effects in predicting positive maternal representations. The results suggest that witnessing aggression in the family affects children's developing beliefs about close relationships and may be a process by which these experiences give rise to later problems in social and emotional functioning.

Marital research in the 20th century and a research agenda for the 21st century

In this article we review the advances made in the 20th century in studying marriages. Progress moved from a self-report, personality-based approach to the study of interaction in the 1950s, following the advent of general systems theory. This shift led, beginning in the 1970s, to the rapid development of marital research using a multimethod approach. The development of more sophisticated observational measures in the 1970s followed theorizing about family process that was begun in the decade of the 1950s. New techniques for observation, particularly the study of affect and the merging of synchronized data streams using observational and self-report perceptual data, and the use of sequential and time-series analyses produced new understandings of process and power. Research in the decades of the 1980s and 1990s witnessed the realization of many secular changes in the American family, including the changing role of women, social science's discovery of violence and incest in the family, the beginning of the study of cultural variation in marriages, the expansion of the measurement of marital outcomes to include longevity, health, and physiology (including the immune system), and the study of comorbidities that accompany marital distress. A research agenda for the 21st century is then described.

Effects of marital conflict on children: recent advances and emerging themes in process-oriented research

BACKGROUND

The effects of marital conflict on children's adjustment are well documented. For the past decade research has increasingly focused on advancing a process-level understanding of these effects, that is, accounting for the particular responses and patterns embedded within specific contexts, histories, and developmental periods that account for children's outcomes over time.

METHODS

As a vehicle for presenting an update, this review follows the framework for process-oriented research initially proposed by Cummings and Cummings (1988), concentrating on recent research developments, and also considering new and emerging themes in this area of research.

RESULTS

In this regard, areas of advancement include (a) greater articulation of the effects of specific context/stimulus characteristics of marital conflict, (b) progress in identifying the psychological response processes in children (e.g., cognitive, emotional, social, physiological) that are affected and their possible role in accounting for relations between marital conflict and child outcomes, (c) greater understanding of the role of child characteristics, family history, and other contextual factors, including effects on children due to interrelations between marital conflict and parenting, and (d) advances in the conceptualization of children's outcomes, including that effects may be more productively viewed as dynamic processes of functioning rather than simply clinical diagnoses.

CONCLUSIONS

Understanding of the impact of marital conflict on children as a function of time-related processes remains a gap in a process-oriented conceptualization of effects. Based on this review, a revised model for a process-oriented approach on the effects of marital discord on children is proposed and suggestions are made for future research directions.

Parental drinking problems and children's adjustment: vagal regulation and emotional reactivity as pathways and moderators of risk

Children's emotional regulation (as indexed by vagal suppression) and children's emotional reactivity during an argument were examined as moderators and mediators of parental problem drinking and children's adjustment in a sample of 6- to 12-year-olds. Cardiac vagal tone was assessed during both a baseline condition and exposure to an audiotaped argument. Vagal suppression was calculated by subtracting vagal tone during the baseline from that recorded during the argument, with a higher number representing increased suppression of vagal tone during the argument. Emotional reactivity was based on both observations of overt behaviors of children and their reported feelings during the argument. A higher level of vagal suppression was a protective factor against children's externalizing, internalizing, and social problems associated with exposure to parental problem drinking. Emotional reactivity was a vulnerability factor, and children's increased anger and fear, and to a lesser degree sadness, each moderated and exacerbated the effects of parental problem drinking on child outcomes.

Evolving the biobehavioral family model: the fit of attachment

The 1993 Biobehavioral Family model (BBFM) posits that family relational patterns and biobehavioral reactivity interact so as to influence the physical and psychological health of the children. The revised 1999 BBFM incorporates parent-child attachment as a pivotal construct. The current study tests the 1999 BBFM by predicting, in asthmatic children, that child perception of parental relationship quality, triangulation of child in marital conflict, and parent-child security of relatedness will be associated with hopelessness and vagal activation (one mechanism of airway compromise in asthma). In this study, 22 children with asthma (11 males/11 females, aged 8 to 16), watched, alone, an emotionally challenging movie, then engaged in family discussion tasks (problem solving, loss, conflict, cohesion) and completed the Children's Perception of Interparental Scale, the Relatedness Questionnaire, The Multidimensional Scale of Anxiety in Children, and the Hopelessness Scale for Children. Heart rate variability, measured at baseline and throughout the movie and family tasks, was used to compute respiratory sinus arrhythmia (RSA)--an inferential measure of vagal activation. The child's perception of parental conflict showed trends of association with triangulation and insecure father-child relatedness. Triangulation and hopelessness also were associated with insecure father-child relatedness, all of which were associated with vagal activation. Insecure mother-child relatedness was correlated only with hopelessness. Anxiety was not related to any variables. These findings lend support to the 1999 BBFM, and suggest a key role for parent-child attachment.

Cardiovascular reactivity and adolescent boys' physical health

OBJECTIVE

Minor illnesses and major diseases are affected by individual, environmental, and social factors. The purpose of the study was to determine if cardiovascular reactivity, an individual characteristic, was related to adolescent boys' health status and behaviors.

METHODS

A total of 89 low socioeconomic status 16-year-old boys who had been classified using teacher ratings during childhood as anxious, disruptive, anxious-disruptive, or normal participated in a laboratory stress experiment. Systolic blood pressure (SBP) and diastolic blood pressure were measured during the Social Competence Interview. Using the upper and lower quartiles of SBP change scores, 21 boys were classified as reactors and 20 boys were classified as nonreactors. Subjects were interviewed to assess health behaviors and outcomes, as well as stressful life events.

RESULTS

No significant group differences were found for minor or major physical health problems. A logistic regression analysis indicated that risky health behaviors were associated with SBP reactivity, personality characteristics, and negative life events. Specifically, nonreactors, who were disruptive, had more negative life events and engaged in more health-compromising behaviors (eg, smoking cigarettes, unprotected sex), which may contribute to future health problems (eg, cancer, AIDS). Anxious individuals may be more vulnerable to cardiovascular diseases in part because of exaggerated cardiovascular reactivity to stress.

CONCLUSION

Low socioeconomic status boys may be at risk for different health problems caused by differing personality characteristics associated with divergent health-related behaviors.

Mothers' and fathers' reports of children's reactions to naturalistic marital conflict

OBJECTIVE

To examine how children, aged 8 to 11 years, react to observing their parents' naturally occurring marital conflict in their own homes and to compare reactions among children raised in homes characterized by different types of marital conflict.

METHOD

For 5 1/2 weeks, mothers and fathers of 110 children used daily home diaries to record independently their children's reactions to marital conflict. Logistic regression compared the likelihood of exhibiting specific reactions to conflict among children from marriages characterized by low conflict (LOWCON; n = 37), nonphysical conflict (NOPHYCON; n = 35), and physical conflict (PHYCON; n = 38).

RESULTS

Mothers' and fathers' reports indicate that children from PHYCON homes were more likely than children from LOWCON and NOPHYCON homes to leave the room, misbehave or appear angry, and appear sad or frightened.

CONCLUSIONS

These results support the notion that different histories of exposure to marital conflict may contribute to the way in which children react to their parents' marital conflict.

Preschoolers' responses to ongoing interadult conflict: the role of prior exposure to resolved versus unresolved arguments

Children's past experiences with interadult conflict are likely to influence their responses to ongoing arguments. Preschoolers' (4- to 5-year-olds) responses to interadult conflict were examined as a function of experimentally manipulated histories of exposure to resolved and unresolved arguments. Children were presented with two live arguments that were either resolved or unresolved, then they were presented with a third argument that was interrupted in progress (i.e., unresolved), and they were interviewed next. Children's overt-behavioral responses were videotaped and coded for distress level. The results support the notion that past experiences with conflict resolution ameliorate children's distress responses to ongoing arguments. In comparison to children previously exposed to unresolved conflict, those exposed to a history of resolved disputes were more likely to (a) exhibit lowered behavioral distress, (b) predict a lower likelihood of a conflictual outcome for the couple's argument, (c) report less negative perceptions of the arguing adults, and were less likely to (d) endorse intervention in conflict through attempts to stop the disputes; (c) and (d) pertained only to girls.

Children's responding to live interadult conflict: the role of form of anger expression

Children's responses to interadult arguments were examined as a function of three forms of disputes: covert, verbal, and physical. Four- to seven-year-olds' overt-behavioral responses to live enactments of arguments between a male and a female were videotaped and coded for behavioral distress and anger/aggression, and children were then interviewed. Although children exhibited overt-behavioral distress in response to all forms of disputes, physical arguments evoked the highest levels of distress. Some gender differences in responding were observed. In comparison to boys, girls exhibited more overt distress during the arguments, and wanted to stop physical arguments more frequently. The results extend findings based on the videotape methodology of the presentation of interadult arguments indicating that form of anger expression impacts children's emotional responding to interadult conflict.
