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.     

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.     

Child anger proneness moderates associations between child-mother attachment security and child behavior with mothers at 33 months

Child-mother attachment security, assessed via a modified Strange Situation procedure (Cassidy & Marvin, with the MacArthur Attachment Working Group, 1992), and parent-reported child proneness to anger were examined as correlates of observed child behavior toward mothers during a series of interactive tasks (N = 120, 60 girls). Controlling for maternal sensitivity and child gender and expressive language ability, greater attachment security, and lower levels of anger proneness were related to more child responsiveness to maternal requests and suggestions during play and snack sessions. As hypothesized, anger proneness also moderated several security-behavior associations. Greater attachment security was related to (a) more committed compliance during clean-up and snack-delay tasks for children high on anger proneness, (b) more self-assertiveness during play and snack for children moderate or high on anger proneness, and (c) more help-seeking during play and snack for children moderate or low on anger proneness. Findings further our understanding of the behavioral correlates of child-mother attachment security assessed during late toddlerhood via the Cassidy-Marvin system and underscore child anger proneness as a moderator of attachment-related differences in child behavior during this developmental period.     

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.     

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.     

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.     

Influence of family of origin and adult romantic partners on romantic attachment security

According to attachment theory, attachment style derives from social experiences throughout the life span. The authors tested this expectation by examining associations between the quality of observed interaction patterns in the family of origin during adolescence and self-reported romantic attachment style and observed romantic relationship behaviors in adulthood (ages 25 and 27). Family and romantic relationship interactions were rated by trained observers from video recordings of structured conversation tasks. Attachment style was assessed with items from D. W. Griffin and K. Bartholomew's (1994a) Relationship Scales Questionnaire. Observational ratings of warmth and sensitivity in family interactions were positively related to similar behaviors by romantic partners and to attachment security. In addition, romantic interactions characterized by high warmth and low hostility at age 25 predicted greater attachment security at 27, after controlling for attachment security at age 25. However, attachment security at age 25 did not predict later romantic relationship interactions after controlling for earlier interactions. These findings underscore the importance of close relationships in the development of romantic attachment security but do not indicate that attachment security predicts the quality of interactions in romantic relationships.     

Differential effects of maternal- and paternal-adolescent attachments on friendship security and intimacy

The present study examined the differential contributions of adolescent-reported maternal and paternal attachment anxiety and avoidance on friendship security and intimacy. Participants were 776 Canadian adolescents between the ages of 13 and 19 years (M = 15.18, SD = 1.58) who provided ratings of their perceived attachment avoidance and anxiety towards their mothers and fathers and responded to measures of friendship security and intimacy. Findings showed that maternal and paternal attachment avoidance and not anxiety negatively predicted friendship security. Moreover, maternal attachment avoidance was negatively associated with friendship intimacy. Multigroup analyses showed that security was negatively predicted by maternal anxious attachment for junior high school boys and girls. Additionally, paternal avoidant attachment was negatively associated with friendship intimacy for junior high school boys and girls. These findings highlight the unique effects associated with maternal and paternal attachment on specific friendship features and underscore the importance of the role of fathers in adolescence.     

The relations between maternal behaviors and urban preschool children's internal working models of attachment security

Interviewed 93 African-American, low-income women who had become pregnant as teenagers and their preschool-aged children in their homes. Mothers answered questions regarding their everyday stresses and feelings of depression. Children were assessed for receptive vocabulary ability, then video-taped completing five stories thematically related to attachment experiences with mother and rated on their security of attachment. Mothers and children were also videotaped playing together, and mothers were assessed on their sensitivity to their children's cues. After controlling for children's age and receptive vocabulary ability, mothers' sensitivity significantly predicted children's level of attachment security. The positive association between maternal sensitivity and children's security of attachment, and the strengths and weaknesses of administering the Attachment Story-Completion Task in the home with this population, are discussed. Implications for assessing attachment in the home are considered.     

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.     

Father involvement, paternal sensitivity, and father-child attachment security in the first 3 years

To reach a greater understanding of the early father-child attachment relationship, this study examined concurrent and longitudinal associations among father involvement, paternal sensitivity, and father-child attachment security at 13 months and 3 years of age. Analyses revealed few associations among these variables at 13 months of age, but involvement and sensitivity independently predicted father-child attachment security at age 3. Moreover, sensitivity moderated the association between involvement and attachment security at 3 years. Specifically, involvement was unrelated to attachment security when fathers were highly sensitive, but positively related to attachment security when fathers were relatively less sensitive. Father involvement was also moderately stable across the two time points, but paternal sensitivity was not. Furthermore, there was significant stability in father-child attachment security from 13 months to 3 years. Secure attachment at 13 months also predicted greater levels of paternal sensitivity at 3 years, with sensitivity at age 3 mediating the association between 13 month and 3 year attachment security. In sum, a secure father-child attachment relationship (a) was related to both quantity and quality of fathering behavior, (b) remained relatively stable across early childhood, and (c) predicted increased paternal sensitivity over time. These findings further our understanding of the correlates of early father-child attachment, and underscore the need to consider multiple domains of fathers' parenting and reciprocal relations between fathering behavior and father-child attachment security.     

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.     

Another look inside the gap: ecological contributions to the transmission of attachment in a sample of adolescent mother-infant dyads

Ecological contributions to attachment transmission were studied in a sample of 64 adolescent mother-infant dyads. Maternal sensitivity was assessed when infants were 6 and 10 months old, and infant security was assessed at 15 and 18 months. Maternal attachment state of mind was measured with the Adult Attachment Interview (AAI) after the 1st assessment. Ecological variables considered were maternal education and depression, paternal support, and infant maternal grandmother support. Results indicated that when the contribution of ecological variables was statistically controlled for, sensitivity was a significant mediator and state of mind no longer contributed to infant security. Sensitivity also mediated an association between maternal education and infant attachment, suggesting that attachment transmission is embedded in a more global process of infant attachment development.     

Exposure to child care,parenting style and attachment security

The present study addressed whether security of attachment is differentiated by quality of parenting and quantity of exposure to child care. Sixty mothers participated with their 14‐month‐old infants, who by the age of 12‐months had received either exclusive maternal care, or varying degrees of exposure to child care. Levels of attachment security were assessed through maternal completion of the Attachment Q‐Set(AQS); parenting quality was assessed through observations of mother–infant interactions during structured tasks. The scores that less sensitive mothers assign their toddlers is higher when their children are in child care for more hours per week; whereas the scores that more sensitive mothers assign their toddlers is lower when their children are in child care for more hours per week. These contrasting patterns suggest that the effects of parenting style on attachment security are moderated by quantity of exposure to child care. Copyright © 2003 John Wiley & Sons, Ltd.     

Attachment in preterm infants and their mothers: Neonatal risk status and maternal representations

High‐risk neonatal status, indexed by an intracranial hemorrhage (ICH), and maternal representations of past and present attachment relationships were examined as predictors of infant attachment in a sample of preterm infants. Participants included 50 19‐month‐old infants and their middle‐class, predominantly African American mothers. A maternal‐report questionnaire and a structured interview were used to assess past relationship history with mother and current relationship with infant, respectively. The Strange Situation Paradigm was used to assess attachment security. Multiple logistic regression analyses suggested that maternal representation of the infant—but not ICH or maternal childhood history—significantly predicted infant attachment security. ICH and maternal history of childhood rejection were predictive of disorganized infant attachment. The findings are consistent with previous data that suggest that maternal factors are more important than infant factors in determining infant attachment security. These data also suggest that neurological deficits may contribute to disorganized infant attachment. © 2000 Michigan Association for Infant Mental Health.     

Both maternal sensitivity and atypical maternal behavior independently predict attachment security and disorganization in adolescent mother-infant relationships

Extant theory holds that variation in attachment security is largely determined by caregiver sensitivity whereas disorganization has its roots in atypical interactions that frighten the infant. These hypotheses were confirmed in the current study of a high-risk sample but, contrary to current theory, both atypical maternal behavior and maternal sensitivity were also significant independent predictors of attachment disorganization and security.     

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.     

The Relation of Maternal Behavior and Attachment Security to Toddlers' Emotions and Emotion Regulation

In this study, we examined characteristics of the mother-child context that may support young children's emotion expressions and emotion regulation. We observed children (N = 154) in four emotion-eliciting episodes to measure their emotion expressions and mother-focused regulation strategies. Mothers reported on the toddlers' attachment security. Lower levels of maternal controlling behaviors and higher levels of attachment security were associated with more adaptive emotion expressions by toddlers, and more maternal positive behavior was associated with more mother-focused regulation. Toddlers' use of mother-focused regulation was also associated with decreased levels of negative affect in positive and fear emotioneliciting tasks but not in frustration tasks. The associations differed for boys and girls and differed depending on the context of the specific emotion elicited.     

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.     

Remaining or becoming secure: Parental sensitive support predicts attachment continuity from infancy to adolescence in a longitudinal adoption study

In a longitudinal study with 125 early adopted adolescents, we examined continuity of attachment from infancy to adolescence and the role of parental sensitive support in explaining continuity or discontinuity of attachment. Assessments of maternal sensitive support and infant attachment (Strange Situation Procedure) were completed when infants were 12 months old. When the children were 14 years old, we observed mothers' sensitive support during a conflict discussion. The adolescents' attachment representations were assessed with the Adult Attachment Interview. Mothers of secure adolescents showed significantly more sensitive support during conflicts than did mothers of insecure adolescents. Overall, no continuity of attachment from infancy to adolescence was found. However, maternal sensitive support in early childhood and adolescence predicted continuity of secure attachment from 1 to 14 years, whereas less maternal sensitive support in early childhood but more maternal sensitive support in adolescence predicted children's change from insecurity in infancy to security in adolescence. We conclude that both early and later parental sensitive support are important for continuity of attachment across the first 14 years of life.
