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.     

母亲积极养育行为对儿童顺从行为的早期预测与双向作用:从婴儿到学步儿

顺从是儿童早期重要的社会化成就。传统理论关注父母控制策略对顺从的作用,但实证结果表明其解释率有限;当前理论更加关注积极养育行为在顺从发展中具有发展适宜性的作用机制。本研究采用追踪设计考察了84个家庭从儿童6个月到3岁时母亲的敏感性和鼓励自主两种积极养育行为与学步儿顺从发展的关系。结果表明:(1)1岁前母亲敏感性对学步儿2岁时的合作性顺从有正向预测作用,对2岁到3岁合作性顺从的变化没有预测作用;(2)1岁前母亲敏感性对学步儿2岁时的情境性顺从和2岁到3岁的情境性顺从的变化均有负向预测作用;(3)在2岁到3岁期间,母亲的鼓励自主与学步儿的合作性顺从水平有双向正向预测作用,但与情境性顺从不存在双向预测关系。     

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.     

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.     

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.     

Emerging effortful control in toddlerhood: the role of infant orienting/regulation, maternal effortful control, and maternal time spent in caregiving activities

Latent growth modeling (LGM) was used to examine the contribution of changes in infant orienting/regulation (O/R) to the emergence of toddler effortful control (EC), the contributions of maternal EC to the development of infant O/R and the emergence of toddler EC, the influence of maternal time spent in caregiving activities on toddler EC and the slope of infant O/R, and the contribution of maternal EC to subsequent maternal time spent in caregiving activities. Mothers from 158 families completed a self-report measure of EC when their infants were 4 months of age, a measure of infant O/R when their infants were 4, 6, 8, 10, and 12 months of age, and a measure of toddler EC when their children reached 18 months of age. Information concerning maternal time spent in various interactive caregiving activities was collected when infants were 6 months old. Results indicated higher maternal EC predicted interindividual differences in the intercept (i.e., higher intercepts), but not slope, of infant O/R and that higher maternal EC, higher infant O/R intercept, and higher infant O/R slope contributed to higher toddler EC. Furthermore, higher maternal EC predicted greater maternal time spent in interactive caregiving activities with their infants and greater maternal time in interactive caregiving with infants also contributed to higher toddler EC after controlling for maternal EC. These findings contribute to the understanding of the influence of maternal EC, directly and through caregiving, on toddler EC. Additional implications as they are related to early developing regulatory aspects of temperament are discussed.     

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.     

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.     

Differential attachment responses of male and female infants to frightening maternal behavior: Tend or befriend versus fight or flight?

Taylor and colleagues (2000) proposed that males tend to display fight or flight responses to threat while females are more likely to display affiliative "tend or befriend" responses. In light of this hypothesis, gender differences in infant attachment behaviors were examined in a sample of 65 low-income mother-infant dyads, half of whom were referred to a home-based intervention service because of concerns about the quality of caregiving. Attachment behaviors were assessed in the Ainsworth Strange Situation when infants were 18 months old, and maternal behaviors were coded both for frightened or frightening behaviors, using the Main and Hesse (1992) coding inventory, and for disrupted affective communication using the Atypical Maternal Behavior Instrument for Assessment and Classification assessment tool (AMBIANCE; Lyons-Ruth, Bronfman, & Parsons, 1999). Results indicated that as maternal behavior became more frightening, female infants tended to approach their mothers more than male infants. These gender differences in response to maternal frightening behavior also were evident in the clinically referred subsample. The results suggest that gender-based differences in tendencies to show affiliative behaviors to threat may complicate interpretation of attachment behavior in clinical contexts.     

Attachment in substance‐exposed toddlers: The role of caregiving and exposure

Prenatal substance exposure is linked to adverse outcomes in children. Some adverse outcomes may result from insecure attachment and low‐quality caregiving rather than from substance exposure. Little is known about the caregiving of polysubstance‐using mothers. To address this, low‐income mothers (n = 41) with their substance‐exposed 12‐month‐olds were compared with a nonexposed group case‐matched for other risk factors. Maternal sensitivity and involvement were analyzed from 2 hr of videotaped interaction. Attachment was assessed using the Attachment Q‐Set. Attachment security and quality of caregiving were quite low for both groups, with no significant differences. In addition, regression analyses revealed that quality of caregiving predicted attachment, but amount of alcohol and cocaine exposure did not. These results suggest that among toddlers with social risk, substance exposure may not predict insecure attachment. Previous research linking attachment to exposure may be better explained by low‐quality caregiving. Implications are that substance‐exposed children, and nonexposed children with comparable social risk, are likely to need intervention to enhance maternal sensitivity and involvement to improve psychiatric outcomes.     

Similarities and differences in mothers' and observers' ratings of infant security on the Attachment Q-Sort

This study examined the similarities and differences in maternal and observer Attachment Behavior Q-Sort ratings (AQS; Waters, 1995) and their relations to dimensions of the developmental ecology - maternal sensitivity, infant irritability, parental stress and psychosocial risk. Data was gathered from low risk (adult mothers; N=44) and high risk mother-infant dyads (adolescent mothers; N=83) when infants were aged 6, 10 and 15 months old, attachment being assessed at 15 months by both mothers and independent observers. A common factor was extracted from both sorts and served to operationalize the similarities between mother and observer ratings. Regressions were conducted to extract maternal and observer AQS scores that were unrelated to each other to represent the difference between the two sorts. Correlation analyses indicated that the common AQS factor was moderately linked to maternal sensitivity and parental stress, and showed a weak association to psychosocial risk and infant irritability. Residual maternal scores showed greater correlations with infant irritability and parental stress than did observer residual scores. Observer scores showed a greater correlation with psychosocial risk than maternal scores. Results suggest that common AQS variance presents a pattern of associations with ecological variables that is coherent with attachment research. Variance related to irritability, stress and risk appear to drive the differences between maternal and observer observations.     

A longitudinal study of the relationship of maternal autonomy support to children's adjustment and achievement in school

A longitudinal study examined the relations of maternal autonomy support to children's school adjustment. Autonomy support and other parenting dimensions were measured when children were 5 years old. School measures were teacher-rated academic and social adjustment and achievement in reading and math in grade 3. Regression analyses controlling for age 5 family and child factors (e.g., socioeconomic status [SES], kindergarten adjustment, IQ) revealed that autonomy support was positively related to grade 3 adjustment (social and academic) and reading achievement. Maternal emphasis on school performance was positively related to achievement measures but negatively related to social adjustment. Maternal use of rewards and praise was unrelated to grade 3 school measures. Finally, supplemental analyses revealed that autonomy support was associated with greater consistency in children's adjustment across social and academic domains as well as higher overall adjustment. These results highlight the developmental significance of parental autonomy support in early childhood.     

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.     

Longitudinal associations between the quality of parent-child interactions and children's sleep at preschool age

This study aimed to examine the prospective longitudinal links between the quality of mother-child and father-child interactions and preschoolers' sleep. Three dimensions of maternal interactive behavior were considered using 70 mother-child dyads, while the quality of father-child interactions was assessed using 41 of these families. Maternal mind-mindedness was assessed at 12 months during a mother-infant free-play sequence, maternal sensitivity was rated at 12 months based on observations performed throughout a home visit, maternal autonomy support was assessed at 15 months with a 10-min problem-solving situation, and the quality of father-child interactions was scored at 18 months, during father-child free play. Children's sleep was assessed at 3 and 4 years using a sleep diary completed by mothers during 3 consecutive days. Results indicated that, after controlling for family socioeconomic status and daycare attendance, the quality of both mother-infant and father-infant interactions was positively related to children's percentage of night-time sleep at preschool age. These findings add to previous literature in suggesting that early caregiving behavior by both mothers and fathers is related to subsequent child sleep.     

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.

Dual trajectories of maternal parenting stress and marital intimacy during toddlerhood

Parenting stress disrupts both parenting and child adjustment. Marital intimacy is often conceptualized as a source of support that may reduce parenting stress. We examined the association between mothers' trajectories of parenting stress and marital intimacy when their children were 15–36 month old. We also explored whether maternal depressive symptoms at 15 months accounted for individual differences concurrently or in the trajectories of parenting stress and marital intimacy. Mothers' marital intimacy was negatively associated with their concurrent levels of parenting stress and declines in parenting stress over time. Depressive symptoms were associated with 15‐month parenting stress and marital intimacy. Overall, intimacy within the marriage appears to be a resource that reduces mothers' parenting stress during the toddler years     

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.     

Caregiving by low‐income adolescent mothers and the language abilities of their 30‐month‐old children

The primary question of interest in this study was: Are the caregiving practices of low‐income, teenage mothers during the first 2 years of their children's lives predictive of individual differences in the language abilities of their 30‐month‐old children? This question was addressed with a sample of 76 teenage mothers and their children who were participating in a family support program. Various measures of caregiving behavior, assessed when the children were 6, 12, and 24 months old, were significantly related to scores on the Preschool Language Scale—3, the Expressive One Word Picture Vocabulary Test, and Receptive One‐Word Picture Vocabulary Tests of the children.     

Possible Insomnia Predicts Some Risky Behaviors Among Adolescents When Controlling for Depressive Symptoms

Attachment theory asserts that secure attachment representations are developed through sensitive and consistent caregiving. If sensitive caregiving is a constant characteristic of the parent, then siblings should have concordant attachment classifications. The authors explored maternal attachment quality assessed by the Attachment Q-Set, maternal sensitivity, and specific mother–child interactions between siblings. Hour-long observations took place in the homes of 9 preschool sibling pairs and their immediate caregivers. The interactions were analyzed using a modified version of Bales’ Small Group Analysis. The results reveal attachment discordance in a third of sibling pairs. While maternal sensitivity was higher with older siblings and mothers displayed more positive emotions when interacting with their younger siblings, attachment quality was not associated with birth order. Therefore, a shift toward a more contextual, family-based perspective of attachment is recommended to further understand how attachment strategies are created and maintained within the child's everyday context.
