Maternal care and attachment security in ordinary and emergency contexts

One of the foundations of attachment theory is the notion that early care plays a key role in determining the quality of child-caregiver attachment relationships. Studies have consistently shown relations between maternal sensitivity and infant security. Further research is required to resolve issues arising from modest correlations, focus on research in stressful as opposed to ordinary contexts, and questions about the generality of results across cultures and social contexts and about the context specificity of caregiving behavior. This article addressed these issues in 2 studies of child care in home and hospital contexts. Q-sort scores derived from extended naturalistic observations were used. Results are discussed in terms of links between methodology and effect sizes, the generality of links between maternal care and child security, the need for further research on caregiving in ordinary and emergency situations, and the context sensitivity of maternal behavior.     

Predicting infant attachment classification from multiple, contemporaneous measures of maternal care

This investigation was designed to test whether stylistic differences in maternal caregiving were associated with both secure and insecure mother-infant attachment classifications in a low-income sample. Multiple measures of maternal interactive behavior and care were collected from a sample of 95 urban, low-income mothers and their 12-month-old infants. Contemporaneous relations to attachment were found only at the broad level of composite scores of caregiving. Scores derived from different measures were aggregated to create composites reflecting three caregiver styles—sensitive, controlling, and unresponsive. Mothers of infants with secure attachment classifications showed greater sensitivity and less controlling behavior than mothers of infants with resistant and avoidant attachments, respectively. Mothers of infants with resistant attachments appeared less responsive to their infants' signals than those of infants with avoidant attachments. Group differences were significant, but modest. These results contribute to the growing body of studies relating parental care with infant attachment patterns and indirectly support the more recent conceptual work on intergenerational transmission of attachment. They also raise methodological issues that need to be considered in future work on caregiving and infant-mother attachment.     

Mothers' personality and its interaction with child temperament as predictors of parenting behavior

In this longitudinal, multimethod investigation, the authors examined mothers' personality and its interaction with infants' negative emotionality as predictors of parenting behavior. When infants were 8-10 months old (N = 112), mothers completed personality self-reports, and the authors observed infants' negative emotionality in both standard procedures and naturalistic daily contexts. When infants were 13-15 months old (N = 108), the authors observed two aspects of parenting, power assertion and maternal responsiveness, in mother-child interactive contexts. Maternal personality alone and also in interaction with child emotionality predicted future parenting behaviors. The longitudinal links established between personality and parenting behaviors indicate the predictive utility of personality. Findings also highlight the bidirectionality of the early parent-child relationship.     

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.     

Emotional availability and attachment representations in kibbutz infants and their mothers.

Three components of the attachment transmission model were examined in 48 kibbutz dyads from 2 kibbutz sleeping arrangements: communal and home-based. Concurrent assessments used the Strange Situation procedure (M. D. Ainsworth, M. C. Blehar, E. Waters, & S. Wall, 1978) for infants' attachment relations, the Adult Attachment Interview (C. George, N. Kaplan, & M. Main, 1985) for mothers' attachment representations, and the Emotional Availability Scales (Z. Biringen, J. L. Robinson, & R. N. Emde, 1993) for emotional availability in the dyads. Security of infants' attachment relations as well as autonomy of mothers' attachment representations were associated with higher emotional availability scores. In addition, significantly poorer emotional availability was found in dyads in which infants were insecurely attached and mothers were nonautonomous. Results also indicate that in the ecology of collective sleeping, the associations between the experience of emotional availability in the dyads and infants' and mothers' attachment may have been disrupted.     

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.     

Stability of Maternal Sensitivity Across Time and Contexts with Q‐Sort Measures

This study examined stability of maternal sensitivity and efficacy of a Q‐sort measure of maternal sensitivity across time and context. Two versions of the maternal behavior Q‐set (MBQS) were employed, first during the Strange Situation Procedure (SSP) and second at home, 2.5 years later based on an available subsample. Findings revealed that the MBQS scores assessed at two time points in two contexts were significantly correlated, showing the stability of maternal sensitivity of the subsample over a time period of 2.5 years. The MBQS scores assigned to mothers of preschoolers were also significantly correlated with their children's early interactive behavioural scores given during the SSP. The current findings further support validating the consistency, the versatility and the efficacy of the MBQS as a sound measure of maternal sensitivity.

Mother-infant interaction and children's socio-emotional development with high- and low-risk mothers

Charting the dynamic character of mother-infant interaction requires using observational systems of sequential coding in real time. A longitudinal study was designed to approach maternal sensitivity in a more complex way using sequential analysis. The study was conducted with 20 high- and 20 low-risk mothers and their infants (aged: 3, 12 and 15 months) to examine the relation among mothers' risk status for physical abuse and their maternal interactive profiles, using micro-social sequential analyses, and the subsequent quality of attachment developed by their children at 15 months of age. Results showed significantly different timings in maternal responses in high- and low-risk groups, that the high-risk mothers were less sensitive: more intrusive and less discriminate regarding their infant's behavior. Significant differences between groups were also found after infant difficult behavior. High-risk mothers' infants were significantly more likely to develop insecure attachment. Sensitivity is proposed as a constellation of timings in early mother-infant interaction.     

Sex differences in infant-mother attachment

A sex difference in security of infant attachment was found in a sample of 52 infant-mother dyads. The infants were enrolled in early care and education programs within a predominantly small-town geographic area in the southwest. Security of attachment was assessed using the Strange Situation procedure. Male infants (76%) were significantly more likely to be securely attached than female infants (39%). No other variables related to the infants' early care and education experience or mothers' age, race, marital status, and education were significantly associated with infants' attachment status.

Quality of attachment,perinatal risk,and mother–infant interaction in a high‐risk premature sample

Thirty‐three families, each with a premature infant born less than 33 gestational weeks, were observed in a longitudinal exploratory study. Infants were recruited in a neonatal intensive care unit, and follow‐up visits took place at 4 months and 12 months of corrected age. The severity of the perinatal problems was evaluated using the Perinatal Risk Inventory (PERI; A.P. Scheiner & M.E. Sexton, 1991 ). At 4 months, mother–infant play interaction was observed and coded according to the CARE‐index (P.M. Crittenden, 2003 ); at 12 months, the Strange Situation Procedure (SSP; M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978 ) was administered. Results indicate a strong correlation between the severity of perinatal problems and the quality of attachment at 12 months. Based on the PERI, infants with high medical risks more frequently tended to be insecurely attached. There also was a significant correlation between insecure attachment and dyadic play interaction at 4 months (i.e., maternal controlling behavior and infant compulsive compliance). Moreover, specific dyadic interactive patterns could be identified as protective or as risk factors regarding the quality of attachment. Considering that attachment may have long‐term influence on child development, these results underline the need for particular attention to risk factors regarding attachment among premature infants.     

Attachment behavior and its antecedents in offspring born to methadone-maintained women

Videotaped 35 full-term, African American infants exposed in utero to methadone and 46 comparison infants at 12 months participating in a separation-reunion procedure to assess aspects of the infant's attachment relationship to the mother. Mothers in the two groups were comparable on education, age (18-35 years), socioeconomic status, parity, IQ and marital status. Offspring born to methadone-maintained women did not differ from comparison infants in indexes of proximity-seeking at reunion but did display higher scores on indexes of disorganized and avoidant behavior and lower scores on indexes of contact-maintaining behavior. Mothers' perceptions during pregnancy of their future infants' degree of bothersomeness were also related to higher scores on contact-maintaining behavior and lower scores on avoidant behavior. Finally, antecedents of attachment behavior within the opioid group alone were considered. The implications of using dimensional attachment ratings for uncovering more subtle attachment antecedents are discussed.     

Genetic and caregiving-based contributions to infant attachment: unique associations with distress reactivity and attachment security

In the longitudinal study reported here, we examined genetic and caregiving-based contributions to individual differences in infant attachment classifications. For 154 mother-infant pairs, we rated mothers' responsiveness to their 6-month-old infants during naturalistic interactions and classified infants' attachment organization at 12 and 18 months using the Strange Situation procedure. These infants were later genotyped with respect to the serotonin-transporter-linked polymorphic region (5-HTTLPR). Maternal responsiveness uniquely predicted infants' attachment security. Infants' 5-HTTLPR variation uniquely predicted their subtype of attachment security at 12 months and their subtype of attachment insecurity at 12 and 18 months. The short allele for 5-HTTLPR was associated with attachment classifications characterized by higher emotional distress. These findings suggest that 5-HTTLPR variation contributes to infants' emotional reactivity and that the degree to which caregivers are responsive influences how effectively infants use their caregivers for emotion regulation. Theoretical implications for the study of genetic and caregiving influences are discussed.     

Maternal Sensitivity: Evidence of Stability across Time,Contexts, and Measurement Instruments

Although maternal sensitivity is widely understood as having a direct impact on the quality of the mother–child relationship, empirical evidence supporting this has been inconsistent, possibly because of varied definitions of the construct and limitations of measurements. The Maternal Behavior Q‐Set (MBQS) appears to be a promising measure of sensitivity, showing associations with attachment security (r = .60) higher than those reported (r = .24) in a highly‐regarded meta‐analysis of other sensitivity measures. The present study aimed to further establish the validity and utility of the MBQS by exploring its consistency with a contingency‐based measure of sensitivity, while also seeking evidence of stability across contexts and times. Seventy‐two mothers and their 10‐month‐olds participated in a procedure that included two episodes of Floor Play and Reunions following maternal differential treatment. Mothers were scored on contingent responsivity and warmth. At 12 months, the dyads underwent the Strange Situation Procedure where sensitivity was assessed using a 72‐item version of the MBQS. The findings revealed the stability of maternal sensitivity across times, contexts, and measures. However, linkages applied only to 10‐month scores from reunion, not play, episodes, supporting Pederson and Moran's (1995) assertion that high‐demand circumstances reveal more meaningful differences in maternal sensitivity.

Perceived quality of maternal care in childhood and structure and function of mothers' brain

Animal studies indicate that early maternal care has long‐term effects on brain areas related to social attachment and parenting, whereas neglectful mothering is linked with heightened stress reactivity in the hippocampus across the lifespan. The present study explores the possibility, using magnetic resonance imaging, that perceived quality of maternal care in childhood is associated with brain structure and functional responses to salient infant stimuli among human mothers in the first postpartum month. Mothers who reported higher maternal care in childhood showed larger grey matter volumes in the superior and middle frontal gyri, orbital gyrus, superior temporal gyrus and fusiform gyrus. In response to infant cries, these mothers exhibited higher activations in the middle frontal gyrus, superior temporal gyrus and fusiform gyrus, whereas mothers reporting lower maternal care showed increased hippocampal activations. These findings suggest that maternal care in childhood may be associated with anatomy and functions in brain regions implicated in appropriate responsivity to infant stimuli in human mothers.     

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.     

Mother-child discourse in two contexts: links with child temperament, attachment security, and socioemotional competence

The goal of this study was to examine whether attachment security and child temperament predicted differences in the elaboration and emotional content of mother-child discourse in 2 contexts and whether those differences were related to a child's socioemotional development. Fifty-one preschool children and their mothers were videotaped reading a storybook and discussing the child's previous behavior. These conversations were coded for maternal elaboration and emotional content. Mothers also completed reports of child temperament, attachment security, and social behavior. Children completed measures of emotional understanding, behavioral internalization, and representations of relationships. The findings suggested that both aspects of mother-child discourse were related to attachment, temperament, and socioemotional competence, although the findings varied depending on the context of the discourse.     

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.
