Directly assessing interpersonal RSA influences in the frequency domain: An illustration with generalized partial directed coherence.

Despite recent research indicating that interpersonal linkage in physiology is a common phenomenon during social interactions, and the well-established role of respiratory sinus arrhythmia (RSA) in socially facilitative physiological regulation, little research has directly examined interpersonal influences in RSA, perhaps due to methodological challenges in analyzing multivariate RSA data. In this article, we aim to bridge this methodological gap by introducing a new method for quantifying interpersonal RSA influences. Specifically, we show that a frequency-domain statistic, generalized partial directed coherence (gPDC), can be used to capture lagged relations in RSA between social partners without first estimating RSA for each person. We illustrate its utility by examining the relation between gPDC and marital conflict in a sample of married couples. Finally, we discuss how gPDC complements existing methods in the time domain and provide guidelines for choosing among these different statistical techniques.

Estimating time-varying RSA to examine psychophysiological linkage of marital dyads.

One of the primary tenets of polyvagal theory dictates that parasympathetic influence on heart rate, often estimated by respiratory sinus arrhythmia (RSA), shifts rapidly in response to changing environmental demands. The current standard analytic approach of aggregating RSA estimates across time to arrive at one value fails to capture this dynamic property within individuals. By utilizing recent methodological developments that enable precise RSA estimates at smaller time intervals, we demonstrate the utility of computing time-varying RSA for assessing psychophysiological linkage (or synchrony) in husband-wife dyads using time-locked data collected in a naturalistic setting.

Posttraumatic stress disorder symptoms impact the emotional experience of intimacy during couple discussions.

We examined the impact of PTSD symptom severity on emotional reactions to one's own and one's partner's intimacy behaviors. Heterosexual, community couples in which at least one partner reported elevated symptoms of PTSD were video-recorded discussing a relationship problem and self-reported their emotions immediately before and after the discussion. Each partner's intimacy behaviors were coded. Actor-Partner Interdependence Models indicate that, among those with greater PTSD symptom severity, partners' caring, understanding, and validation were associated with increased negative emotions, particularly fear. Among those with greater PTSD severity, provision of caring was associated with decreased anger, guilt, and sadness. Therefore, the receipt of intimacy was associated with increased negative emotions among individuals with elevated PTSD symptoms while provision of intimacy was associated with decreased negative emotions. Existing treatments for PTSD should consider the emotional context of provision and receipt of intimacy to more fully address relationship problems among couples dealing with PTSD.

Longitudinal associations between temperament and socioemotional outcomes in young children: the moderating role of RSA and gender.

Temperament is an important predictor of socioemotional adjustment, such as externalizing and internalizing symptoms. However, there is not a one-to-one correspondence between temperamental predispositions and these outcomes, implying that other factors also contribute to the development of internalizing and externalizing problems. Self-regulation is believed to interact with temperament, and has been studied as a predictor for later socioemotional outcomes. Respiratory sinus arrhythmia (RSA) is a psychophysiological measure of self-regulation that has been studied as a moderator of risk. The primary aim of the present study was to test if RSA baseline and RSA reactivity would moderate the link between temperament and socioemotional outcomes. Mothers reported the temperament of their infants (20 months; N = 154), RSA was collected at 24- and 42-months, and mothers reported externalizing and internalizing behaviors at kindergarten entry. RSA baseline and RSA reactivity moderated the relation between exuberant temperament and externalizing behaviors. However, these results were only significant for girls, such that high RSA baseline and greater RSA suppression predicted more externalizing behaviors when exuberance was high. Fearful temperament predicted later internalizing behaviors, but no moderation was present. These results are discussed in light of recent evidence regarding gender differences in the role of RSA as a protective factor for risk.

Within- and between-family differences in cooperative and competitive coparenting.

Coparenting, the coordination between adults in their parental roles, contributes to the functioning of multiple family subsystems. The ecological context model of coparenting posits that multiple factors, including contextual, marital, and child characteristics, influence coparenting behavior (Feinberg, 2003). To date, coparenting has primarily been considered a between-family construct, and the focus has been on examining the factors that account for differences in coparenting across families. There is very limited research exploring variations in coparenting within-families across contexts. To address this gap, the current study explores whether there is significant within- and between-family variation in coparenting. In addition, family, marital, and child correlates of both within- and between-family variation in coparenting are examined. Fifty-eight 2-parent families, drawn from a larger ongoing longitudinal study on children's emotional development, participated in this study. Parents and their children participated in a laboratory visit when children were 42-months-old that included 3 triadic family interaction tasks that were coded to assess cooperative and competitive coparenting, as well as child-centered behavior. In addition, children completed a computerized go/no-go task to assess their inhibitory control and parents completed questionnaires about their marital relationship quality. Results indicated that a substantial portion of the variance in coparenting occurred within families. In addition, the correlates of coparenting cooperation and competition differed.

Cooperative coparenting moderates the association between parenting practices and children's prosocial behavior.

This study examined how aspects of the parenting and coparenting relationships relate to children's prosocial behavior in early childhood. Fifty-eight 2-parent families from a larger ongoing longitudinal study participated in this study. Mothers completed questionnaires that measured their use of inductive reasoning, as well as their children's prosocial behavior. Furthermore, parents and their children participated in 3 triadic interaction tasks that were coded to assess cooperative coparenting behavior. Results revealed that cooperative coparenting was positively associated with children's prosocial behavior. A significant interaction also emerged between maternal inductive reasoning and cooperative coparenting behavior. These findings underscore the important role of a cooperative coparenting subsystem in influencing children's emerging prosocial behavior, as well as highlight the association between positive parenting practices and children's prosocial development within the context of cooperative coparenting behaviors. This study demonstrates the utility of understanding family-level processes that contribute to children's prosocial development during early childhood.

Gender differences in the impact of posttraumatic stress disorder symptoms on community couples' intimacy behaviors.

Problems in intimate relationships frequently occur among individuals with posttraumatic stress disorder (PTSD). This study includes examination of whether deficits in the intimacy process occur among couples affected by PTSD, and whether gender differences exist in the association between PTSD symptom severity and intimate behaviors. Heterosexual community couples in which at least 1 partner was experiencing elevated symptoms of PTSD were video-recorded while discussing positive and negative aspects of their relationship. Each partner's intimacy behaviors (i.e., self-disclosure and support provision) were coded. Results of an actor-partner interdependence model indicate that husbands, but not wives, with greater PTSD symptom severity provided less support (i.e., expressions of understanding, validation, and caring) to their partners during discussions of negative aspects of their relationship. This finding supports prior literature while increasing generalizability beyond samples of male combat veterans and addressing a possible confound of prior research that has exclusively relied on self-reported intimacy. In addition, wives' PTSD symptom severity was associated with husbands engaging in more self-disclosure when discussing negative aspects of their relationship, which may have represented husbands' expression of more negative thoughts and feelings in this context. Overall, women appeared to be resilient against the potential negative impact of PTSD symptoms on their ability to continue providing intimacy behaviors to their partners.

Testing a developmental cascade model of emotional and social competence and early peer acceptance.

A developmental cascade model of early emotional and social competence predicting later peer acceptance was examined in a community sample of 440 children across the ages of 2 to 7. Children's externalizing behavior, emotion regulation, social skills within the classroom and peer acceptance were examined utilizing a multitrait-multimethod approach. A series of longitudinal cross-lag models that controlled for shared rater variance were fit using structural equation modeling. Results indicated there was considerable stability in children's externalizing behavior problems and classroom social skills over time. Contrary to expectations, there were no reciprocal influences between externalizing behavior problems and emotion regulation, although higher levels of emotion regulation were associated with decreases in subsequent levels of externalizing behaviors. Finally, children's early social skills also predicted later peer acceptance. Results underscore the complex associations among emotional and social functioning across early childhood.

Contributions of child's physiology and maternal behavior to children's trajectories of temperamental reactivity.

Trajectories of children's temperamental reactivity (negative affectivity and surgency) were examined in a community sample of 370 children across the ages of 4 to 7 with hierarchical linear modeling. Children's physiological reactivity (respiratory sinus arrhythmia [RSA]), physiological regulation (Delta RSA), and maternal parenting behavior were included as predictors of children's trajectories of temperamental reactivity. Results indicated that negative affectivity and surgency decreased from 4 to 7 years of age; however, within-person changes in negative affectivity were dependent on levels of baseline RSA and not age. Increases in negative affectivity were also predicted by higher levels of earlier maternal controlling behavior. Decreases in surgency were predicted by higher levels of Delta RSA during mother-child interaction tasks and positive parenting behavior. Baseline RSA and maternal controlling parenting also accounted for interindividual differences in children's negative affectivity at age 7, and gender and children's baseline RSA accounted for interindividual differences in children's surgency at age 7. Overall, these results provide further evidence that parenting behavior and children's RSA influence the changes that occur in children's temperamental reactivity.

Predicting emotional and social competence during early childhood from toddler risk and maternal behavior.

The longitudinal associations between maternal parenting behavior and toddler risk with children's emotional and social competence were examined during the transition to kindergarten, in a sample of 253 children. Toddler risk was characterized by early externalizing behavior and poor emotion regulation skills. Given that we were interested in the multiple pathways that may result in emotional and social competence, we examined the interactions among maternal parenting behavior and toddler risk. There were some significant interactions, although the pattern of results was not consistent across all competence outcomes. Maternal parenting behavior was not directly associated with children's emotional and social competence. In some instances, maternal control has differential implications for children's emotional and social competence dependent upon the child's level of early risk and maternal positive parenting. Specifically, maternal control tended to be more detrimental for children's emotional competence during the transition to kindergarten, when children exhibit higher levels of risk. Overall, it appears that there are multiple developmental pathways, depending on child and maternal characteristics that lead to early emotional and social competence.

Individual differences in trajectories of emotion regulation processes: the effects of maternal depressive symptomatology and children's physiological regulation.

Trajectories of emotion regulation processes were examined in a community sample of 269 children across the ages of 4 to 7 using hierarchical linear modeling. Maternal depressive symptomatology (Symptom Checklist-90) and children's physiological reactivity (respiratory sinus arrhythmia [RSA]) and vagal regulation (Delta RSA) were explored as predictors of individual differences in trajectories of emotion regulation and negativity (mother-reported Emotion Regulation Checklist; A. M. Shields & D. Cicchetti, 1997). In addition, the authors explored whether children's physiological regulation would moderate the effect of maternal depressive symptomatology on children's emotion regulation trajectories. Results indicated that over time, emotion regulation increased whereas negativity decreased, though considerable individual variability in the pattern of change was observed. Greater maternal depressive symptomatology was associated with less steep emotion regulation trajectories. There was a significant Maternal Depressive Symptomatology x Baseline RSA x Age interaction predicting emotion regulation trajectories. Overall, it appears that the development of emotion regulation over time is compromised when mothers report greater depressive symptomatology. There is also evidence that children's capacity for physiological regulation can buffer some of the adverse consequences associated with maternal depressive symptomatology.

Parental gentle guidance and children's compliance within the family: a replication study.

In this study, the authors examined the link between young children's compliance and parental gentle guidance from a within-family perspective. Observational data from 57 families (mothers, fathers, and 2 siblings) participating in a family clean-up session were used to replicate earlier findings reported by B. L. Volling, A. Y. Blandon, and B. J. Gorvine (2006). Several of the results were replicated with the authors' older sample. Older siblings used more committed compliance and less passive noncompliance than their younger siblings. Mothers used more gentle guidance than fathers, but no differences were found in their parenting across siblings. Maternal and paternal gentle guidance interacted to explain younger siblings' committed compliance to the father and older siblings' situational compliance. For older siblings' committed compliance and both siblings' passive noncompliance, it was the direct effect of parental gentle guidance that was important. Differential parental gentle guidance appears to have a negative impact on older siblings' compliance. Results underscore the need to explore within-family processes to understand children's early compliance and internalization.

Biological, behavioral, and relational levels of resilience in the context of risk for early childhood behavior problems.

Longitudinal growth patterns of internalizing and externalizing behavior problems were examined in a community sample of 441 children across the ages of 2 to 5 using hierarchical linear modeling. Contextual risk was measured using five indicators (socioeconomic status, marital status, number of siblings, parent stress, parent psychopathology), and three levels of child resilience (biological, behavioral, and relational) were also assessed. Results indicate that a general pattern of decline in both types of behavior problems was observed for the entire sample across time, although considerable individual variability in this pattern was observed. Children's externalizing and internalizing behavior at age 5 was predicted by the level of risk at age 2. All three child resilience factors were also predictive of externalizing and internalizing behaviors at age 5. In the prediction of the slope of problem behavior over time, risk status interacted with both temperamental fearlessness and a mutually responsive orientation with the mother to predict the decline in externalizing and internalizing problem behavior. Results underscore the complex interactions of risk and multiple levels of resilience that are implicated in the maintenance of problem behavior over time. They highlight the importance of considering whether expected resilience factors operate similarly across different levels of risk.

Maternal and paternal gentle guidance and young children's compliance from a within-family perspective.

Young children's early internalization was examined from a within-family perspective. Mothers, fathers, 16-month-old toddlers, and their older siblings from 59 families participated in a family cleanup paradigm to assess young children's compliance and parental guidance. Sibling age differences in compliant and noncompliant behavior were found, with older siblings using more committed compliance and refusal than toddler siblings. Mothers used more gentle guidance with children than did fathers, and both parents used more gentle guidance with older siblings than with toddler siblings. Examining within-family processes indicated that maternal and paternal gentle guidance interacted to predict older and toddler siblings' committed compliance and explained unique variance in the older and toddler siblings' compliance. Some support was found for differential maternal guidance as a within-family process responsible for the development of young children's early self-regulation that may also vary between families.

Social networks among men and women: the effects of age and socioeconomic status.

OBJECTIVES: This study examines the main and interactive effects of age and socioeconomic status (SES) on social networks. METHODS: Respondents are drawn from a regional stratified probability sample aged 40 to 93 years. Hierarchical regression analysis estimates the influence of age and SES on dimensions of social networks, controlling for marital status and health among men and women. RESULTS: Among men, older age was associated with older networks. Professional men report networks that are less geographically proximal, however, occupational effects are most obvious in late life. Among women, age is associated with smaller networks that are older, less geographically proximal, and less frequently contacted. Whereas less education is associated with younger network members in midlife, among women in later life, lower levels of education are not associated with a younger network. Professional women report older networks composed of a higher proportion of friends than do homemakers. Higher levels of education are linked to larger personal networks among men and women, but not to the number of individuals considered closest. Among women, higher levels of education are also associated with less proximal networks. DISCUSSION: An examination of within-group variability reveals influences of age and SES on personal networks among men and women.
