Stability of maternal postnatal bonding between 3 and 6 months: Associations with maternal mental health and infant temperament

Maternal bonding is key for infant development and well-being. Research to date focused on prenatal bonding experience, with fewer studies looking at the postnatal period. Moreover, evidence suggests significant associations among maternal bonding, maternal mental health, and infant temperament. The joint impact of maternal mental health and infant temperament on maternal postnatal bonding remains unclear, with limited research reporting longitudinal data. Hence, the present study aims (1) to explore the impact of maternal mental health and infant temperament on postnatal bonding at both 3 and 6 months of age, (2) to explore postnatal bonding stability from 3 to 6 months, and (3) to determine which factors are linked with 3-to-6-month changes in bonding. At the infants' 3 months (n = 261) and 6 months of age (n = 217), mothers provided measures of bonding, depressive and anxious symptoms, and infant temperament via validated questionnaires. At 3 months, higher levels of maternal bonding were predicted by lower levels of anxiety and depression in the mothers and by higher infants' regulation scores. At 6 months, lower levels of anxiety and depression predicted higher levels of bonding. Moreover, mothers showing decreases in bonding were characterized by 3-to-6-month increases in depression and anxiety, as well as increased reported difficulties in regulation dimensions of infant temperament. This study highlights the impact of both maternal mental health and infant temperament on maternal postnatal bonding in a longitudinal sample and could offer useful information for early childhood prevention and care.     

Identifying the interaction of maternal sensitivity and two serotonin-related gene polymorphisms on infant self-regulation

During infancy, orienting and gaze aversion serve as major self-regulatory mechanisms and play an important role in the development of deliberate self-regulation and control. The present study examined the interaction of intrinsic factors (MAOA-uVNTR and 5-HTTLPR gene polymorphisms) and extrinsic factors (maternal sensitivity) on early infant self-regulatory behavior. We assessed 5-HTTLPR (ss + sl versus ll) and MAOA-uVNTR (3 and 4 among boys, and 3/3, 3/4, and 4/4 among girls) polymorphisms, determined maternal sensitivity during mother–child free play, and coded infant self-regulatory behavior (i.e., orienting shifts in a temperament test) in 281 six-month-old infants. We found that infants who experienced a lower level of maternal sensitivity and had the short allele of 5-HTTLPR variants and the 3/3 MAOA-uVNTR polymorphism displayed lower self-regulation capacity than did those infants with a higher level of maternal sensitivity. This finding suggested a modulatory role of maternal sensitivity. Moreover, these findings are consistent with the genetic vulnerability hypothesis, which states that beneficial environmental factors serve as a buffer against harmful genetic predispositions during child development.     

Maternal sensitivity,infant temperament,and the development of early feeding problems

Early feeding problems, assessed in maternal reports about general problems and refusal behaviors, were investigated in a normal sample (n = 115) at the ages of 10 months and 2 years. In a longitudinal design, stability of feeding problems was studied. A model for development of nonorganic failure to thrive proposed by Chatoor (1989: Chatoor & Egan, 1983) was used as a guide in selection of potential antecedents to early feeding problems. The predictive value of parent-rated infant temperament and directly observed maternal sensitivity for explaining variance in feeding problems was explored. The results showed moderate stability for feeding problems. Feeding problems at both ages were predicted by interactions between infant temperament and maternal sensitivity. At 10 months feeding problems were marginally associated with an interaction between sensitivity and infant manageability (degree of negative emotionality); less sensitive mothers with less manageable infants reported more refusal behaviors. At the age of 2 years irregular infants were reported to have more problems if their mothers were less sensitive to their signals. The results are discussed in relation to studies of more severe feeding problems in infancy, and the Chatoor model was found to contribute to an understanding of the development of everyday infant feeding problems in a normal sample. © 1997 Michigan Association for Infant Mental Health     

Like mother,like child? Maternal determinants of children's early social-emotional development

Social-Emotional competencies evolve early in life. For example, early emotion regulation is learned primarily in the context of mother–child interaction, which may allow for maternal influences to shape children's social-emotional development. The aim of the current study was to longitudinally examine maternal determinants of children's early social-emotional development in a community-based sample of first-time mothers (N = 61, aged 22–39 years). Specifically, we used structural equation modeling to examine how maternal emotion regulation difficulties and subclinical depression directly and indirectly, through sensitivity and postnatal bonding, assessed at 6 to 8 months predicted child outcomes at 12 to 16 months. We found that mothers’ sensitivity predicted fewer social-emotional and behavioral problems and that stronger bonding predicted fewer problems and more social-emotional competencies. Emotion regulation difficulties were significantly associated with depressive symptoms; yet, when accounting for shared variances, both factors differentially predicted less positive child outcomes such that more difficulties indirectly, through poorer bonding, predicted greater delay in competencies, and more symptoms indirectly, through less sensitivity, predicted more problems. Current findings underline the significance of maternal factors impacting the quality of mother–child interaction for children's positive development. Potential implications for early prevention programs to support children who are otherwise at risk for negative emotional outcomes due to mothers’ emotional state postpartum are discussed.     

Pathways from marital aggression to infant emotion regulation: the development of withdrawal in infancy

Associations between marital conflict and infant emotion regulation exist, but explanatory pathways have not been explored. For older children, parental behavior partially mediates this association through a "spillover" process. We test: associations between mothers' and fathers' verbally aggressive marital conflict, infant temperament, and infant withdrawal; mediating effects of negative maternal behavior, and moderating effects of infant temperament, exposure to marital arguments, and contact with father. Eighty mothers, 73 fathers, and their 6-month-old infants participated; parents reported marital aggression prenatally, mothers reported infant exposure to arguments, direct caregiving by father, and infant temperament at 5 months. Negative maternal behavior, infant withdrawal, distress to novelty, activity, and look away were observed at 6 months. Mothers' and fathers' aggressive marital conflict predicted infant withdrawal, interactively with exposure to marital arguments and extent of father caregiving, as did infant temperament and negative maternal behavior. Maternal behavior did not mediate between marital conflict and withdrawal.     

Sustained attention development during the toddlerhood to preschool period: associations with toddlers' emotion regulation strategies and maternal behaviour

The current study examined the role of maternal behaviour and toddlers' emotion regulation strategies in the development of children's sustained attention abilities. Participants for this study included 447 children (232 girls) obtained from three different cohorts participating in a larger ongoing longitudinal study. When the children were 2 years of age, mothers brought their children to the laboratory and were videotaped during several tasks designed to elicit emotion regulation and mother–child interaction. Sustained attention was also measured at the same visit via a laboratory task and in a subsequent visit when children were 4.5 years of age. Results indicated that toddlers' use of help‐seeking emotion regulation strategies was positively related to sustained attention, while avoidance behaviours and maternal behaviour characterized by high levels of overcontrolling/intrusiveness were negatively related to sustained attention at age 2. Significant interactions emerged such that high levels of maternal warmth/responsiveness buffered the negative associations between low use of distraction and high use of self‐comforting emotion regulation strategies and sustained attention at age 2. Maternal behaviour characterized by high levels of warmth/responsiveness also predicted greater growth in sustained attention from age 2 to 4.5. These findings are discussed in terms of how maternal behaviours and children's use of active versus passive emotion regulation strategies relate to sustained attention abilities.

Interaction between maternal and paternal parenting styles with infant temperament in emerging behavior problems

This study examined the interaction effects of infant temperament (negative affect, orienting/regulatory capacity, surgency) on the relationship between maternal and paternal parenting styles (authoritative, authoritarian, permissive) and externalizing and internalizing behaviors simultaneously. A diverse sample of mothers (N = 186) and fathers (N = 142) reported on infant temperament of their 6-month-olds and their children’s internalizing and externalizing behaviors one year later. Significant interactions revealed: (a) surgency moderated maternal authoritative and paternal permissive parenting style and externalizing behaviors; and (b) surgency moderated maternal authoritarian and paternal authoritative parenting style and internalizing behaviors. No significant interactions were found between maternal and paternal parenting styles and their report of their infants’ orienting/regulatory capacity and negative affect. Findings suggest interaction effects may appear beginning in infancy.     

Mothers’ self-reported emotion dysregulation: A potentially valid method in the field of infant mental health

In the current study, we evaluated the extent to which mothers reported emotion dysregulation on the Difficulties with Emotion Regulation Questionnaire (DERS) (a) converged with physiological indices of emotion dysregulation while parenting, (b) correlated with maternal sensitivity, and (c) predicted infant attachment disorganization and behavior problems in a sample of 259 mothers and their infants. When infants were 6 months old, mothers’ physiological arousal and regulation were measured during parenting tasks and mothers completed the DERS. Maternal sensitivity was observed during distress-eliciting tasks when infants were 6 and 14 months old. Infant attachment disorganization was assessed during the Strange Situation when infants were 14 months old and mothers reported on infants’ behavior problems when infants were 27 months old. Mothers who reported greater emotion regulation difficulties were more physiologically dysregulated during stressful parenting tasks and also showed lower levels of maternal sensitivity at 6 months. Mother-reported dysregulation predicted higher likelihood of infant attachment disorganization and more behavior problems. Results suggest that the DERS is a valid measure of maternal emotional dysregulation and may be a useful tool for future research and intervention efforts aimed toward promoting positive parenting and early child adjustment.     

Maternal posttraumatic stress symptoms and infant emotional reactivity and emotion regulation

The current study examined associations between maternal posttraumatic stress disorder (PTSD) symptoms and infant emotional reactivity and emotion regulation during the first year of life in a primarily low-income, urban, ethnic/racial minority sample of 52 mother–infant dyads. Mothers completed questionnaires assessing their own trauma exposure history and current PTSD and depressive symptoms and their infants’ temperament when the infants were 6 months old. Dyads participated in the repeated Still-Face Paradigm (SFP-R) when the infants were 6 months old, and infant affective states were coded for each SFP-R episode. Mothers completed questionnaires assessing infant trauma exposure history and infant current emotional and behavioral symptoms when the infants were 13 months old. Maternal PTSD symptoms predicted infants’ emotion regulation at 6 months as assessed by (a) infant ability to recover from distress during the SFP-R and (b) maternal report of infant rate of recovery from distress/arousal in daily life. Maternal PTSD symptoms also predicted maternal report of infant externalizing, internalizing, and dysregulation symptoms at 13 months. Maternal PTSD was not associated with measures of infant emotional reactivity. Neither maternal depressive symptoms nor infant direct exposure to trauma accounted for the associations between maternal PTSD symptoms and infant outcomes. These findings suggest that maternal PTSD is associated with offspring emotion regulation difficulties as early as infancy. Such difficulties may contribute to increased risk of mental health problems among children of mothers with PTSD.     

Maternal socialization and child temperament as predictors of emotion regulation in Turkish preschoolers

This study investigated the role of maternal socialization and temperament in Turkish preschool children's emotion regulation. Participants consisted of 145 preschoolers (79 boys, 69 girls; M_age= 62 months), their mothers, and daycare teachers from middle‐high socioeconomic suburbs of Istanbul. Maternal child‐rearing practices and emotion socialization behaviours were examined together as interconnected constituents of parenting in relation to emotion regulation skills in young children. Mothers completed a set of questionnaires that measured their child's emotion regulation and temperament as well as their own emotion socialization and child‐rearing behaviours. Teachers also completed a scale that measured the child's ability to regulate emotions. Hierarchical regression analysis showed that child's reactivity negatively and persistence positively predicted emotion regulation. The interaction of maternal responsiveness and child approach–withdrawal also significantly predicted emotion regulation. Simple slope tests were conducted slicing the data in both directions. In the first instance, for children low in Approach, the simple slope of Responsiveness on emotion regulation score was significantly positive. In contrast, for children high in Approach, the simple slope of Responsiveness on emotion regulation score was not significant. In the second instance, for mothers average in Responsiveness, the simple slope of Approach on emotion regulation score was significantly positive. In contrast, for mothers high in Responsiveness, the simple slope of Approach on emotion regulation was not significant. These findings were considered within an interactional model in which positive parenting and inhibited temperament are significant predictors of emotion regulation in Turkish preschoolers.

A cross-cultural study of infant temperament: Predicting preschool effortful control in the United States of America and Russia

Effortful control (EC) has been conceptualized as a dimension of temperament related to self-regulation and associated with the development of executive attention skills. Research has focused on documenting the development of EC, but there has been little systematic study of its precursors. The present study was designed to examine infant temperament characteristics as potential predictors of EC in the toddler/preschool period across two countries: Russia and the USA. Specifically, contributions of negative emotionality (NE), positive affectivity/surgency (PAS), and regulatory capacity/orienting (RCO) measured in the first year of life were expected to explain EC in the preschool period. For the US sample, toddler NE, infant PAS and RCO explained significant amounts of EC variance, whereas infant RCO was the single significant predictor of later EC in the Russian sample. Analyses with the combined sample provided an opportunity to evaluate temperament-by-culture interactions, one of which (PAS×Culture) reached statistical significance. Follow-up analyses indicated that higher levels of infant PAS were related to higher EC scores for US children only, whereas for the Russian youth preschool EC did not vary as a function of infant PAS. Results of this study support the importance of early appearing regulation in contributing to the development of EC and illustrate the value of cross-cultural longitudinal research.     

Maternal prenatal stress and infant regulatory capacity in Mexican Americans

The early postpartum period lays important groundwork for later self-regulation as infants’ dispositional traits interact with caregivers’ co-regulatory behaviors to produce the earliest forms of self-regulation. Although emerging literature suggests that fetal exposure to maternal stress may be integral in determining child self-regulatory capacity, the complex pathways that characterize these early developmental processes remain unclear. The current study considers these complex, transactional processes in a low income, Mexican American sample. Data were collected from 295 Mexican American infants and their mothers during prenatal, 6- and 12-week postpartum home interviews. Mother reports of stress were obtained prenatally, and mother reports of infant temperament were obtained at 6 weeks. Observer ratings of maternal sensitivity and infant regulatory behaviors were obtained at the 6- and 12-week time points. Study results indicate that prenatal stress predicts higher levels of infant negativity and surgency, both of which directly or interactively predict later engagement in regulatory behaviors. Unexpectedly, prenatal stress also predicted more engagement in orienting, but not self-comforting behaviors. Advancing understandings about the nature of these developmental pathways may have significant implications for targets of early intervention in this high risk population.     

Maternal and Infant Temperament Characteristics as Contributors to Parenting Stress in the First Year Postpartum

Although prominent models emphasize that maternal, child, and situational variables are associated with parenting stress, previous research has often neglected to examine associations between maternal and infant temperament characteristics and stress experienced in the parenting role. Additionally, while predictors of global parenting stress have been examined, predictors of stress related to specific aspects of the parenting role have been largely unexplored. The present study examined maternal and infant temperament characteristics as predictors of parenting stress, both globally and specifically. Mothers (n = 159) completed measures of depressive and anxiety symptoms and a measure of adult temperament when their infants were 4 months old. At 6 months postpartum, caregivers completed a measure of infant temperament, and at 8 months postpartum, a measure of parenting stress. Results indicated that maternal effortful control and infant negative emotionality predicted global maternal parenting stress. Additionally, all maternal and infant temperament variables, with the exception of maternal negative affectivity and infant surgency/extraversion, were uniquely predictive of at least one specific aspect of parenting‐related stress. Findings emphasize the importance of considering maternal and infant temperament characteristics as contributors to parenting stress in the first year postpartum. Implications of these findings for future research and intervention are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Cardiac physiological regulation across early infancy: The roles of infant surgency and parental involvement with mothers and fathers

High baseline respiratory sinus arrhythmia (RSA) and infant temperament are associated with a child’s ability to self-regulate, but moderators of this association have not been thoroughly examined in the literature. Parents who are more involved might have more opportunities to interact with and soothe their children. The current study examined whether parental involvement moderated the association between infant temperament and baseline RSA with mothers and fathers across early infancy. Participants included families (n = 91) assessed at 4 and 8 months of age. Infant temperamental surgency and parental involvement were measured via parent-report when infants were 4 months old, and infant baseline RSA was measured at 4 and 8 months of age. Results revealed differences in mother versus father predictors of infant baseline RSA. A significant Infant Surgency X Maternal Play interaction was revealed; infants of mothers who were low involvement increased in their baseline RSA as their surgency increased. A significant main effect of father care was found; infants with highly involved fathers had higher baseline RSA. In conclusion, mothers and fathers may differentially influence their infant’s cardiac physiological regulation based on their specific type of involvement.     

Trajectories of externalizing behavior from age 2 to age 9: relations with gender, temperament, ethnicity, parenting, and rater

Trajectories of children's externalizing behavior were examined using multilevel growth curve modeling of data from the NICHD Study of Early Child Care and Youth Development. According to ratings by both mothers and caregivers/teachers when children were 2, 3, 4, 7, and 9 years old, externalizing behavior declined with age. However, mothers rated children as higher in externalizing behavior than did caregivers and teachers. Higher levels of age 9 externalizing behavior were predicted by the following factors: child male gender (for caregiver/teacher reports only), infant difficult temperament (for children with harsh mothers only), harsher maternal attitude toward discipline, higher level of maternal depression (for maternal reports only), and lower level of maternal sensitivity (especially for boys). Caregivers and teachers reported higher levels of externalizing behavior in African American children than in European American children, increasingly so over time; mothers' ratings revealed the reverse. The declining slope of externalizing behavior was predicted by infant difficult temperament for mother reports only. Additional analyses suggested that the association between parenting and externalizing behavior was bidirectional.     

Infant Emotion Regulation Strategy Moderates Relations between Self‐Reported Maternal Depressive Symptoms and Infant HPA Activity

Children of mothers with depressive symptoms often have high cortisol levels. Research shows that various child characteristics (e.g., attachment pattern, internalizing behaviours, and temperament) moderate this association. We suggest that these characteristics share common variance with emotion regulation strategy. Therefore, we examine infant emotion regulation strategy as a moderator of the association between maternal depressive symptoms and infant hypothalamic–pituitary–adrenal (HPA) function. We hypothesize that infants who utilize more independent emotion regulation strategies and have mothers who report higher depressive symptoms will exhibit elevated cortisol levels. Participants were 193 mothers and infants (15 months old) recruited from the community. Self‐reported maternal depressive symptoms were assessed. Infant independent regulatory behaviours (withdrawal, wandering away, distraction, scanning, orienting to another object) were coded in the context of a Toy Frustration Task. Infant cortisol was collected via saliva samples at baseline, +20, and +40 minutes. Results indicate that infant emotion regulation strategy moderates the relation between mothers' self‐reported depressive symptoms and infant total cortisol output (AUC_G) and cortisol reactivity (AUC_I). Infants who employed more independent regulatory behaviours and have mothers with higher depressive symptoms experience greater cortisol secretion. We discuss the findings in relation to parent‐infant interactions and the adaptive nature of emotion regulation strategies, as they relate to HPA regulatory capacities.

Maternal self-regulation,relationship adjustment,and home chaos: Contributions to infant negative emotionality

There has been increasing interest in the direct and indirect effects of parental self-regulation on children's outcomes. In the present investigation, the effects of maternal self-regulation, home chaos, and inter-parental relationship adjustment on broad and specific indicators of infant negative emotionality (NE) were examined. A sample of maternal caregivers and their 4-month-old infants (N = 85) from a rural community participated. Results demonstrated that better maternal self-regulation was associated with lower infant NE broadly, as well as with lower infant sadness and distress to limitations/frustration and better falling reactivity (i.e., emotion regulation), specifically. Maternal self-regulation also predicted less chaotic home environments and better maternal inter-parental relationship adjustment. Findings also supported the indirect effects of maternal self-regulation on broad and specific indicators of infant NE through home chaos and maternal relationship adjustment. Some differential effects were also identified. Elevated home chaos appeared to specifically affect infant frustration/distress to limitations whereas maternal relationship adjustment affected broad infant NE, as well as several specific indicators of infant NE: frustration/distress to limitations, sadness, and falling reactivity. In conjunction with other recent investigations that have reported the effects of maternal self-regulation on parenting, the findings in the present investigation suggest that parental self-regulation may influence children's outcomes through several proximal environmental pathways.     

Moral Emotions,Emotion Self-Regulation,Callous-Unemotional Traits,and Problem Behavior in Children of Incarcerated Mothers

Children with incarcerated mothers are at high risk for developing problem behaviors. Fifty children (6–12 years; 62% girls) participated in summer camps, along with adult mentors. Regression analyses of child and adult measures of child’s emotion self-regulation and callous-unemotional traits, and a child measure of moral emotions, showed that poor emotion regulation, along with low levels of guilt and high levels of shame, predicted children’s externalizing behaviors, while only low levels of guilt predicted a unique subset of child characteristics called callous-unemotional traits. Children who experienced healthy guilt for misdeeds were better able to control their behavior. Adults noted the ability of children with callous/unemotional traits to manage and regulate their emotions, while poor emotion regulation was more predictive of the cluster of externalizing problems. Discussion focuses on prevention efforts aimed at teaching emotion self-regulation and the implications of the high levels of callous-unemotional traits in this population of children.     

Maternal postnatal psychiatric symptoms and infant temperament affect early mother-infant bonding

Postnatal mother-infant bonding refers to the early emotional bond between mothers and infants. Although some factors, such as maternal mental health, especially postnatal depression, have been considered in relation to mother-infant bonding, few studies have investigated the role of infant temperament traits in early bonding. In this study, the effects of maternal postnatal depressive and anxiety symptoms and infant temperament traits on mother-infant bonding were examined using both mother and father reports of infant temperament. Data for this study came from the first phase of the FinnBrain Birth Cohort Study (n = 102, father reports n = 62). After controlling for maternal symptoms of depression and anxiety, mother-reported infant positive emotionality, measured by infant smiling was related to better mother-infant bonding. In contrast, infant negative emotionality, measured by infant distress to limitations was related to lower quality of bonding. In regards to father-report infant temperament, only infant distress to limitations (i.e., frustration/anger) was associated with lower quality of mother-infant bonding. These findings underline the importance of infant temperament as one factor contributing to early parent-infant relationships, and counseling parents in understanding and caring for infants with different temperament traits.
