My mother is sensitive,but I am too tired to know: Infant sleep as a moderator of prospective relations between maternal sensitivity and infant outcomes

This study investigated the moderating role of infant sleep in the connections between maternal sensitivity and three indicators of infant functioning: attachment security, theory of mind, and executive functioning (EF). Maternal sensitivity was assessed when infants (27 girls and 36 boys) were 1 year of age. Infant sleep was assessed with actigraphy at age 2; attachment security, theory of mind, and EF were also assessed at age 2. Results indicated that maternal sensitivity was positively related to attachment security only among infants who got more sleep at night, and to conflict-EF and theory of mind only for infants who got greater proportions of their sleep during the night. These results suggest that sleep may enhance the benefits of maternal sensitivity for some aspects of infants’ functioning, providing further support for the importance of sleep maturation as a salient developmental task of infancy.     

Non-verbal and verbal parental mentalization as predictors of infant attachment security: Contributions of parental embodied mentalizing and mind-mindedness and the mediating role of maternal sensitivity

Interest in studying the relative contributions of verbal (e.g., maternal mind-mindedness [MM]) and non-verbal dimensions (i.e., parental embodied mentalizing [PEM]) of parental mentalization to child socio-emotional development is relatively recent. To date, only one study has addressed this issue in relation to child attachment security, suggesting a complementary and unique contribution of each one. The purpose of the present study was to further examine the specific contribution of PEM to infant attachment security by considering MM. In addition, this study aimed to explore the mediating role of maternal sensitivity linking PEM, MM to infant attachment security within 110 mother-infant dyads at moderate psychosocial risk. The two dimensions of parental mentalization (PEM and MM) were assessed on the basis of observations made during a videorecorded sequence of mother-child interactions in a context of free play with and without toys when the infants were 8 months old. The Maternal Behavior Q-Sort was used to measure the mothers’ sensitivity in a natural setting based on observations of daily mother-child interactions, also when the infants were about 8 months old. Attachment security was measured using The Strange Situation Procedure at infant age 16 months. The results showed positive correlations between maternal sensitivity and both verbal and non-verbal measures of parental mentalization. The mediation analyses first revealed that PEM had a significant indirect effect on attachment security, with sensitivity being identified as a mediator in this association. No indirect effect linking MM and attachment security via sensitivity was observed. These results highlight the contribution of PEM to maternal sensitivity and show maternal sensitivity to be a factor that partly explains the influence of PEM on attachment security in children.     

In search of shared and nonshared environmental factors in security of attachment: a behavior-genetic study of the association between sensitivity and attachment security

The current article presents results from a twin study of genetic and environmental components of maternal sensitivity and infant attachment and their association. The sample consisted of 136 twin pairs from 2 sites: Leiden, the Netherlands, and London, UK. Maternal sensitivity was assessed in the home at 9-10 months, and infant attachment security was observed in the laboratory at 12 months. The study yielded little evidence that genetic factors are involved in variations between twins in maternal sensitivity ratings but did find that shared variance in maternal sensitivity was able to account for some of the similarity between twins in attachment security. Weak nonshared associations between sensitivity and attachment appeared to suppress the magnitude of the correlation between attachment and sensitivity in twin children. The results could indicate that the attachment security of one twin may depend on the relationship the parent has with the other twin. The results are brought to bear on the validity of attachment theory as a theory of primarily shared environmental effects in children's development and the continuing challenge posed to attachment theory by within-family differences in socioemotional processes.     

On the relation between maternal state of mind and sensitivity in the prediction of infant attachment security

Attachment theorists assume that maternal mental representations influence responsivity, which influences infant attachment security. However, primary studies do not support this mediation model. The authors tested mediation using 2 mother-infant samples and found no evidence of mediation. Therefore, the authors explored sensitivity as a moderator, studying the (a) interaction of mental representation and sensitivity as it predicts infant attachment security and (b) level of sensitivity in mothers whose infants' attachment security is either concordant or discordant with their own. The interactional analyses were not significant. But the match-mismatch data showed that when mother-infant attachment strategies were discordant, maternal sensitivity was more consistent with infant than maternal attachment strategy. These findings are congruent with an interpretation of sensitivity as a moderator that can block transmission of attachment strategy.     

A dimensional approach to maternal attachment state of mind: relations to maternal sensitivity and maternal autonomy support

The aim of this study was to examine the developmental significance of the newly developed dimensional approach to attachment state of mind by investigating its capacity to predict individual differences in the quality of two caregiving behaviors-maternal sensitivity and maternal autonomy support-that are linked to numerous important child outcomes. Seventy-one upper-middle-class, predominantly French-speaking and Caucasian dyads participated in 3 home visits (34 girls). The Adult Attachment Interview (AAI) was administered when the infants were 8 months old, maternal sensitivity was assessed when they were 12 months old, and maternal autonomy support was assessed at 15 months. The results revealed that, above and beyond SES, maternal sensitivity was negatively related to the dismissing dimension of the AAI, whereas maternal autonomy support was negatively linked to the preoccupied/unresolved dimension. In contrast, the traditional AAI categories were not significantly linked to parenting. These results speak to the relevance of using a continuous approach to attachment state of mind when predicting individual differences in specific caregiving behaviors.     

Exploration of the links among fathers' unresolved states of mind with respect to attachment,atypical paternal behavior,and disorganized infant–father attachment

Atypical maternal behavior has consistently been identified as a precursor of disorganized infant–mother attachment, but to date, no research has examined the role of atypical paternal behavior in the development of disorganized infant–father attachment. This study aims to enhance our understanding and conceptualization of infant–father attachment by examining the role of fathers' unresolved states of mind and the display of atypical paternal behavior in the development of disorganized infant–father attachment. Thirty‐one middle‐class couples participated in this study. Maternal and paternal Adult Attachment Interviews (C. George, N. Kaplan, & M. Main, 1996 ) were completed prenatally and at infant age 6 months, respectively. Infant–mother and infant–father dyads participated in the Strange Situation paradigm (M. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978 ) when the infants were 12 and 18 months of age, respectively. The Atypical Maternal Behavior Instrument for Assessment and Classification (E. Bronfman, E. Parsons, & K. Lyons‐Ruth, 1999 ) was used to assess maternal and paternal behavior during the Strange Situation. Maternal states of mind regarding attachment predicted infant–mother attachment relationships, and paternal states of mind predicted infant–father attachment relationships. Atypical maternal behavior was associated with infant–mother disorganized attachment; however, atypical paternal behavior did not predict infant–father disorganized attachment. Thus, it is possible that other factors, yet to be uncovered, might contribute to the development of infant–father disorganized attachment.     

Associations between maternal mind-mindedness and infant attachment security: investigating the mediating role of maternal sensitivity

In the last 20 years, three meta-analyses suggested that the relation between maternal sensitivity and infant attachment security was lesser in magnitude than originally believed. This led to a search for other parental behaviors likely to contribute to the development of attachment security. Based on previous theoretical propositions and empirical findings suggesting that maternal mind-mindedness may contribute to infant attachment security by favoring maternal sensitivity, the aim of this study was to examine whether sensitivity mediates the relation between maternal mind-mindedness and infant attachment security. Fifty mother-infant dyads took part in two home visits (12 months and 15 months), allowing for assessment of maternal sensitivity (T1), mind-mindedness (T1), and infant attachment (T2). The results confirmed that maternal sensitivity mediates the relation between mind-mindedness and infant attachment. The findings are discussed in light of the assessments used in this and previous studies.     

INSIGHTFULNESS AND LATER INFANT ATTACHMENT IN CLINICALLY DEPRESSED AND NONCLINICAL MOTHERS

The aim of this pilot study was to investigate the relationship between maternal insightfulness and sensitivity and subsequent infant attachment security and disorganization in clinically depressed and nonclinical mother–infant groups. Nineteen depressed mothers with infants ages 3 to 11 months participated in this study. Twenty nonclinical mother–infant dyads were matched to the clinical sample according to infant sex and age. Maternal depression was assessed using the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (American Psychiatric Association, 1994), insightfulness using the Insightfulness Assessment (IA), and sensitivity using the Maternal Sensitivity Scales (M.D.S. Ainsworth, 1969). IA classifications and subscales were considered separately. Later infant attachment was assessed by the Strange Situation Procedure (M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978). Depressed mothers tended to have less securely attached children than did nonclinical mothers. Within the clinical sample, the insightfulness categories correlated slightly moderately with attachment security, but were not related to attachment disorganization. Within the nonclinical sample, the IA categories were slightly moderately associated with attachment security and with disorganization. On IA subscales, relationship patterns differed in clinically depressed and nonclinical mother–infant dyads. These findings provide the first evidence of the predictive power of the IA categorization and subscales on subsequent infant attachment. They also may allow the development of different foci of intervention for enhancing insightful caregiving.     

Reflection in thought and action: Maternal parenting reflectivity predicts mind‐minded comments and interactive behavior

Recent research has identified mothers' mental reflective functioning and verbal mind‐minded comments as important predictors of subsequent infant attachment security. In the present study, we examine associations between mothers' (N = 95) parenting reflectivity expressed in an interview and observed parenting behavior, including verbal mind‐minded comments and interactive behavior during interaction with their 7‐month‐old infants. Parenting reflectivity was coded from the Working Model of the Child Interview. Maternal behavior was assessed via observations of mother–infant interaction during free play and structured teaching tasks. Both maternal appropriate mind‐minded comments as well as other indicators of maternal interactive behavior were coded. Parenting reflectivity was positively correlated with mind‐minded comments and behavioral sensitivity. Hierarchical multiple regression analyses indicated that parenting reflectivity contributed to maternal behavior beyond the contributions of mothers' educational status and depression symptoms. Discussion emphasizes the importance of individual differences in parental capacity to accurately perceive and mentalize their infants' experience, and the consequences of these differences for caregiving behavior.     

An examination of the impact of maternal fetal attachment,postpartum depressive symptoms and parenting stress on maternal sensitivity

The current study aimed to examine the impact of maternal depression, maternal fetal attachment (MFA) and parenting stress on maternal sensitivity, intrusiveness and positive regard for the child with a sample of 36 low-income, mothers-infant dyads that were followed from pregnancy through the first year postpartum. Maternal depression and parenting stress were expected to have a negative impact on maternal sensitivity, intrusiveness and positive regard, while high MFA was hypothesized to have a positive impact on these three outcomes. Our data provide partial support for our hypotheses. Findings from this study add to the literature by examining the stability of the maternal prenatal and postpartum bond with her infant as well as by looking at the impact of parenting stress on maternal behaviors and processes that may lead to later attachment security differences, such as maternal sensitivity and responsiveness.     

Maternal sensitivity in interactions with three‐ and 12‐month‐old infants: Stability,structural composition,and developmental consequences

This study addresses three topics related to the structural components of maternal sensitivity: (a) The stability of sensitivity over a nine‐month period, (b) the predictability of maternal sensitivity assessed at 12 months from early parameters of parenting and (c) the relation between maternal sensitivity and developmental outcomes assessed at 12 months. Maternal sensitivity and its components (signal perception, correct interpretation, prompt, and appropriate reaction) were evaluated for 60 mother–infant‐dyads when their infants were aged three and 12 months. Additional parameters of early parenting were maternal emotional warmth and behavioural contingency. Developmental outcome measures were the amount of infant crying and the quality of attachment at twelve months. The results showed close correlations between the sensitivity components suggesting a unidimensional structure for maternal sensitivity. The sensitivity assessments were significantly related to measures of maternal warmth. Stability of maternal sensitivity over time was, however, quite low. There was no relation between the early sensitivity assessments and later developmental outcomes, whereas there was a significant relation between the sensitivity parameters assessed at twelve months and developmental outcomes. The results indicate changes in the meaning of maternal sensitivity during infants' development. Copyright © 2004 John Wiley & Sons, Ltd.     

Infant emotion regulation: Relations to bedtime emotional availability,attachment security,and temperament

The present study examines the influences of mothers’ emotional availability toward their infants during bedtime, infant attachment security, and interactions between bedtime parenting and attachment with infant temperamental negative affectivity, on infants’ emotion regulation strategy use at 12 and 18 months. Infants’ emotion regulation strategies were assessed during a frustration task that required infants to regulate their emotions in the absence of parental support. Whereas emotional availability was not directly related to infants’ emotion regulation strategies, infant attachment security had direct relations with infants’ orienting toward the environment and tension reduction behaviors. Both maternal emotional availability and security of the mother–infant attachment relationship interacted with infant temperamental negative affectivity to predict two strategies that were less adaptive in regulating frustration.     

Predicting maternal reactivity/sensitivity: The role of infant emotionality,maternal depressiveness/anxiety,and social support

It was hypothesized that an accumulation of unfavorable conditions, i.e., high negative emotionality and low positive emotionality of the infant, maternal depression and anxiety, and lacking social and emotional support can attenuate mothers' reactivity/sensitivity. Maternal reactivity/sensitivity was observed during home visits and in the laboratory. Infant negative and positive emotionality was assessed by mother reports and behavioral observations. Maternal depressiveness/anxiety as well as social support were assessed via questionnaires. All mothers were primiparous and had healthy infants. Data collection was conducted at the infants' ages of four months (37 dyads) and eight months (33 dyads). The sample consisted of 19 male and 18 female infants (four‐months' measurement). Whereas the presence of a single risk factor was not related to maternal reactivity/sensitivity, the combination was. A decrease in maternal reactivity/sensitivity over the course of time was demonstrated for mothers who had to deal with high negative emotionality of the infant in combination with either high depressiveness/anxiety or low social support at the infants' age of four months. No significant main or interaction effects could be shown for infant positive emotionality. ©2004 Michigan Association for Infant Mental Health.     

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 attachment representations in relation to emotional availability and discipline behaviour

Maternal attachment representations have been investigated in relation to sensitivity and emotional support, but rarely in relation to other important areas of daily parent–child interactions in early childhood, like limit setting and discipline strategies. This study investigates maternal attachment representations in relation to parenting sensitive and discipline behaviours. The sample consists of 37 Portuguese high-risk severely economically disadvantaged mothers and their 1- to 4-year-old children, that responded to the Adult Attachment Interview, and were observed in play and discipline interaction contexts. The results showed that a more preoccupied state of mind was related to less emotional availability in free play interaction with child. A more secure attachment representation was related to more psychologically controlling discipline tactics. These findings highlight the relevance of maternal attachment states of mind in understanding parenting practices in several domains, and are discussed in light of sociocultural factors.     

Social and individual determinants of infant attachment security and disorganization

The aim of this study was to assess individual and social antecedents of attachment security and attachment disorganization of infants as assessed by the Strange Situation. Observations from two longitudinal studies, with a parallel assessment schedule yielding a total sample of 88 infant-mother pairs, formed the database of the study. Newborn behavioral organization, in terms of orienting ability and regulation of state, and maternal sensitivity assessed several times during the infant's first year were used to predict the security of infant-mother attachment and the status of disorganization of attachment behavior strategies at the age of 12 months. Whereas attachment security was significantly associated only with maternal sensitivity, the status of disorganization was only predicted by newborn behavioral organization. The findings are discussed with respect to specific assumptions about individual and social contribution to the development of infant-mother attachment on the background of maternal attachment representation.     

Goodness of fit between prenatal maternal sleep and infant sleep: Associations with maternal depression and attachment security

The current study prospectively examined the ways in which goodness of fit between maternal and infant sleep contributes to maternal depressive symptoms and the mother-child relationship across the first years of life. In a sample of 173 mother-child dyads, maternal prenatal sleep, infant sleep, maternal depressive symptoms, and mother-child attachment security were assessed via self-report, actigraphy, and observational measures. Results suggested that a poor fit between mothers’ prenatal sleep and infants’ sleep at 8 months (measured by sleep diary and actigraphy) was associated with maternal depressive symptoms at 15 months. Additionally, maternal depression mediated the association between the interplay of mother and infant sleep (measured by sleep diary) and mother-child attachment security at 30 months. Findings emphasize the importance of the match between mother and infant sleep on maternal wellbeing and mother-child relationships and highlight the role of mothers’ perceptions of infant sleep.     

A social‐contextual understanding of concordance and discordance between maternal prenatal representations of the infant and infant–mother attachment

This prospective study examined the relationship between maternal prenatal representations of the infant and later infant–mother attachment, including contextual factors related to concordance and discordance among dyads over time. Participants were 173 pregnant women between the ages of 18 and 40 who were interviewed during their last trimester of pregnancy and 2 and 13 months after birth. Maternal representations were assessed by the Working Model of the Child Interview during pregnancy (WMCI; C.H. Zeanah, D. Benoit, L. Hirshberg, M.L. Barton, & C. Regan, 1994), and infant–mother attachment was assessed through the Strange Situation procedure (M.D.S. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978) when infants were 13 months old. There was substantial discordance between maternal and infant classifications, although a significant concordance rate was found when classifications were collapsed into balanced/secure and nonbalanced/insecure groups based on prenatal representations and postnatal infant attachment groups (60%; χ² = 6.90, p < .01; κ .20). As expected, discordance between maternal representations and infant–mother attachment was meaningfully related to contextual risk factors, maternal depression, and infant behaviors.     

THE EYE OF THE BEGETTER: PREDICTING INFANT ATTACHMENT DISORGANIZATION FROM WOMEN'S PRENATAL INTERPRETATIONS OF INFANT FACIAL EXPRESSIONS

Infant–caregiver attachment disorganization has been linked to many long‐term negative psychosocial outcomes. While various prevention programs appear to be effective in preventing disorganized attachment, methods currently used to identify those at risk are unfortunately either overly general or impractical. The current investigation tested whether women's prenatal biases in identifying infant expressions of emotion—tendencies previously shown to relate to some of the maternal variables associated with infant attachment, including maternal traumatization, trauma symptoms, and maternal sensitivity—could predict infant attachment classification at 18 months postpartum. Logistic regression analyses revealed that together with women's adult history of high betrayal traumatization, response concordance with a normative reference sample in labeling infant expressions as negatively valenced, and the number of infant facial expressions that participants classified as “sad” and “angry” predicted subsequent infant attachment security versus disorganization. Implications for screening and prevention are discussed.
