Examining the Link Between Infant Attachment and Child Conduct Problems in Grade 1

Abtract  We examined the extent to which infant attachment status is directly related to child conduct problems 6 years later, and assessed the potential mediating roles of hostile parenting and maternal depression. The sample included 84 adolescent mothers and their children (45 girls, 39 boys). Infant attachment status was assessed using the Strange Situation when the study children were 1-year-old. Hostile parenting was coded during a parent–child interaction task when the study children were 4.5-years-old. Maternal depression was self-rated, also when the study children were 4.5-years-old, using the Beck Depression Inventory. Mothers reported child conduct problems at Grade 1 on the Child Behavior Checklist. Infant attachment status at 1 year of age was directly related to child conduct problems but not to hostile parenting or maternal depression. Neither hostile parenting nor maternal depression mediated the relationship between infant attachment status and child conduct problems. However, the pattern of relations differed by attachment security. For securely attached children, maternal depression, but not hostile parenting, was directly related to conduct problems. For insecurely attached children, hostile parenting, but not maternal depression, was directly related to child conduct problems. Implications for intervention and future research are discussed.     

Infant frontal EEG asymmetry moderates the association between maternal behavior and toddler negative affectivity

Relatively little work has examined potential interactions between child intrinsic factors and extrinsic environmental factors in the development of negative affect in early life. This work is important because high levels of early negative affectivity have been associated with difficulties in later childhood adjustment. We examined associations between infant frontal electroencephalogram (EEG), maternal parenting behaviors, and children’s negative affect across the first two years of life. Infant baseline frontal EEG asymmetry was measured at 5 months; maternal sensitivity and intrusiveness were observed during mother-child interaction at 5 and 24 months; and mothers provided reports of toddler negative affect at 24 months. Results indicated that maternal sensitive behaviors at 5 months were associated with less negative affect at 24 months, but only for infants with left frontal EEG asymmetry. Similarly, maternal sensitive behaviors at 24 months were associated with less toddler negative affect at 24 months, but only for infants with left frontal EEG asymmetry. In contrast, maternal intrusive behaviors at 5- and 24-months were associated with greater toddler negative affect, but only for infants with right frontal EEG asymmetry at 5-months. Findings suggest that levels of negative affect in toddlers may be at least partially a result of interactions between children’s own early neurophysiological functioning and maternal behavior during everyday interactions with children in the first two years of life.     

Infant characteristics and parental engagement at the transition to parenthood

Positive engagement activities support children's adaptive development and new parents are encouraged to be highly engaged with infants. Yet, fathers’ engagement is widely understudied and maternal engagement quantity is frequently overlooked. Our study contributes to growing knowledge on associations between infant temperament and parental engagement by testing transactional and moderation models in a recent sample of first-time parents when infants were 3, 6, and 9 months old. Stringent longitudinal, reciprocal structural equation models partially confirmed an engagement “benefit”. Mothers’ engagement marginally contributed to their children's gains in effortful control from 3 to 6 months regardless of child gender. Further, mothers’ engagement reduced infant negative affect from 6 to 9 months regardless of child gender. Mothers’ ratings of infant negative affect were gendered; mothers’ ratings of infant negative affect increases more from 3 to 6 months for boys. Fathers’ engagement was contextually sensitive; child gender moderated the link between negative affect and engagement from 6 to 9 months, such that fathers became more engaged with boys whom they rated higher on negative affect; there was no effect for daughters. Finally, we found that effortful control moderated associations between negative affect and maternal engagement; mothers’ engagement increases from 3 to 6 months were greater for children initially rated lower in effortful control. Implications for future research and parenting education and support services are discussed.     

Maternal sensory sensitivity, mother-infant 9-month interaction, infant attachment status: predictors of mother-toddler interaction at 24 months

At 24-months of age, toddlers (N=62) and their mothers were observed in a free-play session to determine the contribution of (a) maternal sensory sensitivity to positive and negative infant facial expressions as measured in a signal detection task at 6 months, (b) maternal behavior and affect, infant behavior and affect, and dyadic interaction at 9 months, and (c) infant attachment status at 12 months in predicting maternal, toddler, and dyadic measures at 24 months. Hierarchical regression analyses revealed that over and above early maternal behavior, which was predictive of later maternal behavior at 24 months, sensory sensitivity to the positive infant expression at 6 months predicted maternal behavior at 24 months and sensory sensitivity to both the positive and negative expression was associated with later maternal affect. Infant attachment status emerged as the variable which predicted toddler behavior and dyadic interaction at 24 months.     

Affect Attunement and Maternal Attachment: A Pilot Study

The notion that individual differences in mothers' representations of their own early childhood attachment relationships impede or facilitate the recognition of an infant's experiences and needs was investigated. Women were classified as secure, dismissing, of preoccupied in relation to attachment on the basis of the Adult Attachment Interview (George, Kaplan, & Main, 1985) and then videotaped in a laboratory setting with their 10- to 13-month-old babies. Maternal attunement behaviors and fantasies about the babies during the attunement moment were recorded and examined in light of individual differences in maternal attachment. The findings reveal that securely attached mothers are more attuned to their babies than are those mothers who are insecurely attached. Secure mothers attune to a range of infant affect, whereas insecure mothers attune to particular affects and not to others. Specifically, dismissing mothers tended not to attune to negative affect, whereas preoccupied mothers randomly attuned to both positive and negative affect states. Qualitative analyses suggest that insecure mothers misattune to infant affects that threaten their internalized attitudes toward attachment. The findings support the hypothesis that the nature of a mother's internal affective experience powerfully influences the affects she acknowledges and attunes to in her child.     

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.     

Maternal self-efficacy, knowledge of infant development, sensory sensitivity, and maternal response during interaction

When their infants were 6 months of age, mothers were assessed for self-efficacy (low, moderate, and high illusory control) and knowledge of infant development to determine their impact on mothers' behavioral sensitivity and affect during a feeding task at 9 months (N=70). Mothers' sensory sensitivity to digital images of infants' negative and positive expressions assessed in a signal detection task at 6 months was hypothesized to mediate this relation. Mothers with moderate illusory control exhibited greatest behavioral sensitivity and positive affect. Low knowledge was associated with reduced sensitivity for mothers with low illusory control only. When viewing the negative expression, mothers with moderate illusory control and high knowledge exhibited greatest sensory sensitivity, and mothers with high illusory control and moderate/high knowledge were least sensitive. Although sensory sensitivity was not a mediating variable, its relation to both illusory control and subsequent maternal measures during feeding was informative. Although greater sensory sensitivity predicted more sensitive behavior and more positive affect, only for maternal affect was the relation independent of illusion of control effects.     

Mothers' insightfulness regarding their infants' internal experience: relations with maternal sensitivity and infant attachment

This study examined the associations among mothers' insightfulness into their infants' internal experience, mothers' sensitivity to their infants' signals, and infants' security of attachment to their mothers. The insightfulness of 129 mothers of 12-month-old infants was assessed by showing mothers 3 videotaped segments of observations of their infants and themselves and interviewing them regarding their infants' and their own thoughts and feelings. Interviews were classified into 1 insightful and 3 noninsightful categories. Mothers' sensitivity was assessed during play sessions at home and at the laboratory, and infant-mother attachment was assessed with the Strange Situation. Mothers classified as positively insightful were rated as more sensitive and were more likely to have securely attached children than were mothers not classified as positively insightful. Insightfulness also accounted for variance in attachment beyond the variance explained by maternal sensitivity. These findings add an important dimension to research on caregiving, suggesting that mothers' seeking of explanations for the motives underlying their infants' behavior is related to both maternal sensitivity and infant attachment.     

Impact of fathers' alcoholism and associated risk factors on parent–infant attachment stability from 12 to 18 months

This study examined short‐term attachment stability and sought to identify predictors of stability and change within a sample characterized by fathers' alcoholism. Results suggest moderate stability of attachment classifications (60% for mothers, 53% for fathers) from 12 to 18 months. Higher paternal and maternal alcohol symptoms, maternal depression, and maternal antisocial behavior were found in families with stable insecure mother–infant attachment compared to those who were stable secure. Mother–infant stable insecurity was associated with higher levels of maternal negative affect expression during play. Father–infant stable insecurity was associated with lower levels of paternal positive affect expression and decreased sensitivity during play. Stable insecure children also had higher levels of negative affect during parent–infant interactions and higher negative emotionality during other episodes compared to stable secure children. Results indicate that infants who were insecure at both time points had the highest constellation of family risk characteristics.     

Feeding and attachment in infants with and without orofacial clefts

Do the many feeding problems associated with isolated cleft palate (CP) and cleft lip and palate (CLP) adversely affect the emotional bond between mother and infant? This question was addressed by observing the feeding interactions of 126 mother-infant pairs (57 infants with CLP or CP) at 3 and 12 months of age. Infants with CLP were found to be less communicative during feeding at 3 month than comparison group infants. However, by 12 months, the CLP group had improved to a level indistinguishable from the CP and comparison groups. This change was unrelated to the timing of cleft palate surgery. Although maternal sensitivity during feeding at 3 months did not predict the attachment quality of infants with clefts, maternal sensitivity at 12 months was concurrently related to attachment. Change in maternal sensitivity between 3 and 12 months was also predictive of attachment in the cleft groups, with mothers of avoidant infants showing greater attenuation in maternal sensitivity than the mothers of secure infants.     

Robust patterns and individual variations: Stability and predictors of infant behavior in the still-face paradigm

In the present study we examined key issues regarding infant behavior in the still-face paradigm (SFP) in terms of individual variations, stability, and predictors. The sample consisted of 115 mothers and infants, with assessments at ages 3 and 6 months, including observations of maternal and infant behavior in the SFP, and parent reports of infant temperament. Both robust patterns and individual variations in infant SFP behaviors were found, with only a minority of infants showing the expected patterns for negative affect and gaze. Infant behavior patterns showed no stability from age 3 to 6 months, and infant gaze was related to more pronounced behavior changes across the SFP. Maternal sensitivity in the SFP baseline was related to some aspects of infant SFP behavior. Consistent with the differential susceptibility hypothesis, in infants with a more difficult temperament maternal sensitivity predicted a more pronounced expected pattern of changes in infant positive affect across the SFP, whereas this was not the case for infants with a more easy temperament.     

Associations among average parental educational attainment,maternal stress,and infant screen exposure at 6 months of age

Evidence suggests that increased use of screens early in life may have negative developmental consequences for children. However, little is known concerning parental factors that predict initial screen exposure in infancy. The primary goal of this study was to examine whether parental educational attainment and maternal stress were associated with infant screen exposure by 6 months of age. A diverse sample of mothers (N = 93) was recruited prenatally. In a follow-up visit when the infants were six months of age (N = 82), we examined factors that may be associated with initial infant exposure to screens. First, mothers reported whether they had already exposed their infants to screens. Thereafter, those mothers who reported already having exposed their infants to screens were further queried to determine the extent of infant screen use. Results demonstrated that among infants exposed to screens, mothers reported an average of nearly 3 h of daily screen use. Average parental educational attainment, but not maternal stress, was significantly associated with initial infant exposure. Of those families who endorsed screen exposure by 6 months, 70 % reported a screen in the room where the child sleeps, nearly half reported using screens to help calm the infant, and about a third reported using a screen at least sometimes during meals, when going to sleep, and while waiting. Parental education around infant screen use behaviors may be important to help promote child development and outcomes.     

Infant–mother attachment security and children's anxiety and aggression at first grade

With a large and diverse sample of children from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, the role of infant–mother attachment security as a protective factor against the development of children's anxious and aggressive behaviors at first grade was examined. When child's sex, family income, maternal sensitivity, and prior levels of anxiety and aggression were controlled for, attachment security at 15 months of age was found to moderate the effects of negative life events families experienced, thereby protecting children from experiencing symptoms of anxiety, but not aggression, at 4.5 years of age. Children classified as insecurely attached at 15 months of age who experienced many stressful life events exhibited more anxiety symptoms in first grade than children classified as securely attached who similarly experienced many negative life events. These findings are interpreted within attachment theory, which predicts that early attachment security has a unique role in children's anxiety experiences later in childhood.     

The Relation Between Mothers’ Attitudes Toward Maternal Employment and Social Competence of 36-Month-Olds: The Roles of Maternal Psychological Well-Being and Sensitivity

The relation of mothers’ attitudes on the effects of maternal employment on children, psychological well-being, sensitivity of the mother, and children’s socioemotional development were examined in mothers who worked full time (consistently) and mothers who were unemployed during their children’s early years of growth from 6 months of age. Longitudinal observations of 1,213 mothers and children from age 1 to 36 months from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care were analyzed using structural equation models. Mothers and children benefited when maternal attitudes were consistent with the mothers’ actual employment status. Among consistently employed mothers, those with positive attitudes about employment had better psychological well-being. When mothers who were unemployed, they believed that maternal employment would have positive consequences for their children’s development, they preferred working outside home and they were more likely to show a low level of psychological well-being and poor quality of mother-child relation. Additionally, maternal well-being mediated the relation between a mother’s attitudes and a child’s social competence. For both groups, better psychological well-being of mothers was positively related to better child’s socioemotional outcome. Maternal sensitivity, however, did not mediate the relation between maternal attitudes and child’s social outcomes. The findings shed light on the need for a sensitive measure of characterizing mothers who work versus those who stay at home in order to better understand the effects on a child’s development.     

Shared Affect and Dyadic Synchrony Among Secure and Insecure Parent–Toddler Dyads

The present investigation explored the role of shared affect in parent–child dyadic synchrony during toddlerhood and examined if patterns of dyadic synchrony and shared affect differ for secure and insecure parent–child dyads. Data were collected from 128 families with toddler age children (67 girls and 61 boys) during a laboratory assessment. Mother–toddler and father–toddler interactions were coded for shared positive and negative affect, as well as dyadic synchrony. Attachment status was assessed using the Strange Situation. Data revealed that securely attached parent–toddler dyads spent more time in synchronous interaction, and less time in asynchronous interaction, than insecurely attached parent–toddler dyads. Parent–toddler synchronous interaction among both securely and insecurely attached dyads was characterized by shared positive affect. Among insecure dyads, shared negative affect was more predominate in asynchronous than in synchronous interaction. The role of individual differences in the manifestation of synchronous interaction among securely and insecurely attached parent–toddler dyads is discussed.

The mediating role of maternal responsiveness in some longer term effects of postnatal depression on infant development

We hypothesized a mediating role for low maternal responsiveness in certain child developmental deficits found previously to be associated with postnatal depression. Forty depressed inpatients and 48 control (non-depressed) mothers and their infants were followed until 42 months postpartum. Mother–infant interactions were impaired at 6 months postpartum in the depressed group. Subsequent cognitive deficits were found in children's Full Scale IQ on the Wechsler Preschool Primary Scale of Intelligence (Revised) at 42 months of age. Statistical modeling of the mediation hypothesis confirmed that these effects were overwhelmingly explained by lowered maternal responsiveness at 6 months. Similarly, increased temperamental difficulties were apparent in children of depressed mothers but were not correlated with maternal responsiveness. Male infants of depressed mothers were disproportionately vulnerable (compared to females) to impaired cognitive abilities associated with maternal depression. The data concur with previous work and provide empirical support for the theoretical prediction that early disturbances of the mother–infant interaction will mediate some developmental deficits in the children of depressed mothers.     

Behavioural precursors of attachment representations in middle childhood and links with child social adaptation

Concordance between age‐6 attachment behaviour and age‐8 doll play attachment representations during the school‐age period, and associations between these measures and child social adaptation at school were examined. One hundred and twenty‐nine 6‐year‐olds and their mothers participated in a separation/reunion protocol. Two years later, 104 children completed a doll play narrative task. Teachers evaluated child behaviour problems and prosocial behaviour at both ages. Results showed a significant four‐way concordance between age‐6 attachment behaviour and age‐8 doll play classifications. Each of the four attachment classifications was concordant in the absence of major negative life‐events, but only the disorganized classifications remained concordant when at least one negative life‐event occurred between the two assessment times. Children with a disorganized attachment classification or representation had higher externalizing scores than secure and avoidant children at both timepoints. Finally, the avoidant and disorganized behavioural classifications predicted avoidant and disorganized representations, respectively, even when controlling for age‐6 teacher reports of social adaptation.     

Precursors of social emotional functioning among full-term and preterm infants at 12 months: Early infant withdrawal behavior and symptoms of maternal depression

This study forms part of a longitudinal investigation of early infant social withdrawal, maternal symptoms of depression and later child social emotional functioning. The sample consisted of a group of full-term infants (N = 238) and their mothers, and a group of moderately premature infants (N = 64) and their mothers. At 3 months, the infants were observed with the Alarm Distress Baby Scale (ADBB) and the mothers completed the Edinburgh Postnatal Depression Scale (EPDS). At 12 months, the mothers filled out questionnaires about the infants’ social emotional functioning (Infant Toddler Social Emotional Assessment and the Ages and Stages Questionnaire-Social Emotional). At 3 months, as we have previously shown, the premature infants had exhibited more withdrawal behavior and their mothers reported elevated maternal depressive symptoms as compared with the full-born group. At 12 months the mothers of the premature infants reported more child internalizing behavior. These data suggest that infant withdrawal behavior as well as maternal depressive mood may serve as sensitive indices of early risk status. Further, the results suggest that early maternal depressive symptoms are a salient predictor of later child social emotional functioning. However, neither early infant withdrawal behavior, nor gestational age, did significantly predict social emotional outcome at 12 months. It should be noted that the differences in strength of the relations between ADBB and EPDS, respectively, to the outcome at 12 months was modest. An implication of the study is that clinicians should be aware of the complex interplay between early infant withdrawal and signs of maternal postpartum depression in planning ports of entry for early intervention.     

The relationship between negative parenting and child and maternal temperament

The purpose of the present study was to examine how negative parenting, namely coercive and abusive parenting, relates to maternal and child temperamental characteristics, based on Belsky’s model of parenting. In addition to the unique effects of child temperamental characteristics (approach, perceptual sensitivity, soothability, persistence, and reactivity), we investigated how child temperamental characteristics play a moderating role between maternal temperamental characteristics (negative affect, effortful control, extraversion and orienting sensitivity) and negative parenting. Participants were 209 mothers of preschool children (M_age = 50.01 months, SD = 5.75) from 48 child care centers across the capital city of Turkey. Two sets of hierarchical regression analyses showed that coercive parenting was predicted by child reactivity, perceptual sensitivity, maternal negative affect, and effortful control. In addition, maternal SES and negative affect were related to abusive parenting. Furthermore, interaction between maternal extraversion and child’s persistence predicted coercive parenting. For children with high levels of persistence, maternal extraversion levels did not make any difference in the level of abusive parenting. However, for children with low levels of persistence, mothers who had high levels of extraversion were more likely to display coercive parenting. Consistent with Belsky’s model, both child and maternal characteristics were related to parenting. While both maternal and child characteristics were associated with coercive parenting, only maternal negative effect was associated with abusive parenting.

     

The relationship between quality of attachment in infancy and IQ in kindergarten

In this study, we hypothesized that securely attached infants would in kindergarten perform better on an intelligence test than anxiously attached children. No difference was expected between children of working mothers (working more than 15 hours outside the home) and children of full-time homemakers. Mother-child pairs (N = 77; average age of child was 24 months) were observed during the Strange Situation procedure; three years later, 65 children completed the Leiden Diagnostic Test for measuring intelligence level. Results showed that the securely attached reference group attained the highest IQ. The working status of the mother did not appear to make a difference.
