Maternal Sensitivity

The relation between mother–infant coordinated interpersonal timing, an automated microanalytic measure of dyadic vocal coordination, and maternal sensitivity was explored. Thirty-five mothers and their developmentally normal 4-month-old infants were audio-recorded during a 20-min laboratory vocal interaction session, that was later analyzed for degree of vocal coordination. Maternal Sensitivity ratings (Ainsworth & Bell, 1969) were based on a video-taped 45-min unstructured

Challenges with childhood emotion regulation may have origins in infancy and forecast later social and cognitive developmental delays, academic difficulties, and psychopathology. This study tested whether markers of emotion dysregulation in infancy predict emotion dysregulation in toddlerhood, and whether those associations depended on maternal sensitivity. When children (N = 111) were 7 months, baseline respiratory sinus arrhythmia (RSA), RSA withdrawal, and distress were collected during the Still Face Paradigm (SFP). Mothers' reports of infant regulation and orientation and maternal sensitivity were also collected at that time. Mothers' reports of toddlers' dysregulation were collected at 18 months. A set of hierarchical regressions indicated that low baseline RSA and less change in RSA from baseline to stressor predicted greater dysregulation at 18 months, but only for infants who experienced low maternal sensitivity. Baseline RSA and RSA withdrawal were not significantly associated with later dysregulation for infants with highly sensitive mothers. Infants who exhibited low distress during the SFP and who had lower regulatory and orienting abilities at 7 months had higher dysregulation at 18 months regardless of maternal sensitivity. Altogether, these results suggest that risk for dysregulation in toddlerhood has biobehavioral origins in infancy but may be buffered by sensitive caregiving.

Internalizing symptoms such as withdrawn and anxious-depressed behavior are common in adolescence. This prospective longitudinal study helps to gain insight into the development of internalizing behavior, focusing on the role of early parent-child interaction while ruling out genetic similarity as a confounder. More specifically, the central question addressed in this study was whether parental sensitivity and child inhibited temperament predict children's withdrawn and anxious-depressed behavior in middle childhood and adolescence. We followed 160 early-adopted children (53% girls) from infancy to adolescence. Structural equation modeling was used to test relationships both prospectively and concurrently. The results revealed that more sensitive parenting in infancy and middle childhood predicted less inhibited behavior in adolescence, which in turn predicted fewer internalizing problems in adolescence. The findings suggest that maternal sensitivity lowers adolescents' inhibited behavior and decreases the risk for adolescents' internalizing problem behavior indirectly through lower levels of inhibition. Supporting sensitive parenting in the years before adolescence may protect children from developing inhibited behavior and internalizing behavior problems in adolescence.

The current thesis focuses on the longitudinal development of early-adopted children in the Leiden Longitudinal Adoption Study (LLAS). In the LLAS, adopted children were followed from infancy until young adulthood. In Chapter 1 we discuss the role of sensitive parenting and the precursors and developmental outcomes of attachment security. In the empirical study in Chapter 2 we report on the concurrent as well as longitudinal relations between maternal sensitivity, child temperament, and externalizing behavior problems. In the second empirical study in Chapter 3, we follow this line of enquiry and investigate concurrent and longitudinal relations between maternal sensitivity, child temperament and internalizing behavior problems. Chapter 4 reports on the final empirical study of the thesis, and focuses on the associations between maternal sensitivity and attachment in infancy and the diurnal cortisol curve in young adulthood. Our empirical studies show that maternal sensitivity in in...

Parental reflective functioning is thought to provide a missing link between caregivers' own attachment histories and their ensuing parenting behaviors. The current study sought to extend research on this association involving 115 parents, both mothers and fathers, of 5-to-6-year-old preschoolers using the German version of the Parental Reflective Functioning Questionnaire (PRFQ). Our study was the first to combine Adult Attachment Interview classifications of parental attachment, behavioral observations of parental sensitivity and PRFQ ratings while drawing on a sizable father subsample. We found theoretically consistent significant relations between all measures, while our results particularly highlighted the role of dismissing attachment for decreases in parenting quality on both cognitive and behavioral levels as the dismissing status differentially affected specific components of self-reported parental reflective functioning and observed sensitivity. Interestingly, these patterns were largely comparable in mothers and fathers. Exploratory mediation analyses further suggested that decreased parental reflective functioning may partially mediate the relationship between parents' dismissing attachment and decreased parental sensitivity. Thus, for prevention and intervention programs targeting parental sensitivity and thus children's long term healthy mental development, the interplay between parental reflective functioning and parents' own attachment history emerges as a key mechanism. Finally, our study served as a further validation of the PRFQ given the caveat that the pre-mentalizing subscale may need further revision in the German version.

About 15% of mothers suffer from postpartum psychiatric disorders, such as depression, anxiety, or psychosis. Numerous studies have shown maternal caregiving behavior to be negatively affected under these circumstances. The current study sets out to shed light on specific caregiving behaviors of affected mothers in the context of parental mental illness at an early stage. There are several methods to assess maternal caregiving behavior in terms of sensitivity. However, all of them have limitations regarding the peculiarities of mothers with postpartum disorders, that is, changes in affect regulation, and the early onset of the disorder postpartum. With the current study, we provide an adapted method to assess maternal sensitivity based on methods recently approved in attachment research. Two groups of mothers, who were either healthy or had different postpartum disorders, were recorded on video during interactions with their infants. Behaviors were rated regarding responsiveness, promptness, appropriateness, intrusiveness, and positive and negative affect. A first analysis revealed an increased number of deficits on all subscales in mothers with postpartum psychiatric disorders as compared to healthy mothers. Depressive mothers with a single diagnosis had lower scores in responsiveness, promptness, and appropriateness and higher scores on intrusiveness as compared to those in healthy mothers. Here, maternal behavior appears more parent-centered, whereas affect seemed to be relatively unharmed. Moreover, as compared to healthy mothers, mothers with comorbid depression and anxiety symptomatology achieved lower scores on responsiveness, appropriateness, and positive affect and higher scores on intrusiveness and negative affect. It is suggested, that increased deficits are related to the severity of illness in mothers with comorbidities. Results on promptness indicate that these mothers are still capable of maintaining higher vigilance to infant cues. Variance in maternal behavior was relatively high in clinical mothers, showing that some of them are well capable of behaving in

Theory suggests that early experiences may calibrate the "threshold activity" of the hypothalamus-pituitary-adrenal axis in childhood. Particularly challenging or particularly supportive environments are posited to manifest in heightened physiological sensitivity to context. Using longitudinal data from the Family Life Project (N = 1,292), we tested whether links between maternal sensitivity and hypothalamus-pituitary-adrenal axis activity aligned with these predictions. Specifically, we tested whether the magnitude of the within-person relation between maternal sensitivity and children's cortisol levels, a proxy for physiological sensitivity to context, was especially pronounced for children who typically experienced particularly low or high levels of maternal sensitivity over time. Our results were consistent with these hypotheses. Between children, lower levels of mean maternal sensitivity (7-24 months) were associated with higher mean cortisol levels across this period (measured as a basal sample collected at each visit). However, the magnitude and direction of the within-person relation was contingent on children's average levels of maternal sensitivity over time. Increases in maternal sensitivity were associated with contemporaneous cortisol decreases for children with typically low-sensitive mothers, whereas sensitivity increases were associated with cortisol increases for children with typically

This study evaluated continuity and change in maternal-child hypothalamic-pituitary-adrenal axis attunement in early childhood. Participants were drawn from a prospective study of 1,292 motherchild dyads, which were racially diverse, predominantly low-income, and non-urban. Child focused stress tasks designed to elicit anger, fear, and frustration were administered during early infancy, later infancy, and toddlerhood. Mothers' and children's saliva samples (later assayed for cortisol) were collected before and after the tasks. The strength of mother-child adrenocortical attunement was conserved across infancy and toddlerhood. The magnitude of maternal-child adrenocortical attunement decreased in response to the child-focused stress tasks. Maternal sensitivity and the child's task-related emotional reactivity moderated adrenocortical attunement across the task, with greater maternal sensitivity during a free-play, and lower levels of child emotional reactivity during the stress tasks, stabilizing attunement from pre-to post-task levels. The findings advance our understanding of individual differences in the social regulation of adrenocortical activity in early childhood.

The study evaluated the association between maternal disrupted communication and the reactivity and regulation of the psychobiology of the stress response in infancy. Mothers and infants were recruited via the National Health Service from the 20% most economically impoverished data zones in a suburban region of Scotland. Mothers (N = 63; M age = 25.9) and their 4‐month‐old infants (35 boys, 28 girls) were videotaped interacting for 8 min, including a still‐face procedure as a stress inducer and a 5‐min coded recovery period. Saliva samples were collected from the dyads prior to, during, and after the still‐face procedure and later assayed for cortisol. Level of disruption in maternal communication with the infant was coded from the 5‐min videotaped interaction during the recovery period which followed the still‐face procedure. Severely disrupted maternal communication was associated with lower levels of maternal cortisol and a greater divergence between mothers' and infants'...

Parental care has a strong impact on neurodevelopment and mental health in the offspring. Although numerous animal studies have revealed that the parental brain is a highly complex system involving many brain structures and neuroendocrine systems, human maternal parenting as a multidimensional construct with cognitive, emotional, and behavioural components has not been characterised comprehensively. This unique multi‐method analysis aimed to examine patterns of self‐reported and observed parenting from 6 to 60 months postpartum in a cohort of 496 mothers (mean maternal age = 32 years). Self‐report questionnaires assessed motivational components of mothering, parenting stress, parenting‐related mood, maternal investment, maternal parenting style, mother‐child relationship satisfaction, and mother‐child bonding at multiple time points. Observed parenting variables included the Ainsworth Sensitivity Scales at 6 and 18 months, the Behavioral Evaluation Strategies Taxonomies at 6 months,...

We examined maternal depression and maternal sensitivity as mediators of the association between maternal childhood adversity and her child's temperament in 239 mother–child dyads from a longitudinal, birth cohort study. We used an integrated measure of maternal childhood adversity that included the Childhood Trauma Questionnaire and the Parental Bonding Index. Maternal depression was assessed with the Edinburgh Postnatal Depression Scale at 6 months postpartum. Maternal sensitivity was assessed with the Ainsworth maternal sensitivity scales at 6 months. A measure of “negative emotionality/behavioral dysregulation” was derived from the Early Childhood Behaviour Questionnaire administered at 36 months. Bootstrapping-based mediation analyses revealed that maternal depression mediated the effect of maternal childhood adversity on offspring negative emotionality/behavioral dysregulation (95% confidence interval [0.026, 0.144]). We also found a serial, indirect effect of maternal chi...

Disorganized attachment is an important early risk factor for socioemotional problems throughout childhood and into adulthood. Prevailing models of the etiology of disorganized attachment emphasize the role of highly dysfunctional parenting, to the exclusion of complex models examining the interplay of child and parental factors. Decades of research have established that extreme child birth weight may have long-term effects on developmental processes. These effects are typically negative, but this is not always the case. Recent studies have also identified the dopamine D4 receptor (DRD4) as a moderator of childrearing effects on the development of disorganized attachment. However, there are inconsistent findings concerning which variant of the polymorphism (seven-repeat long-form allele or non-seven-repeat short-form allele) is most likely to interact with caregiving in predicting disorganized versus organized attachment. In this study, we examined possible two- and three-way intera...

Background: Large population-based studies suggest that systematic measures of maternal sensitivity predict later risk for overweight and obesity. More work is needed to establish the developmental timing and potential moderators of this association. The current study examined the association between maternal sensitivity at 6 months of age and BMI z score measures at 48 months of age, and whether sex moderated this association. Design: Longitudinal Canadian cohort of children from birth (the MAVAN project). Methods: This analysis was based on a dataset of 223 children (115 boys, 108 girls) who had structured assessments of maternal sensitivity at 6 months of age and 48-month BMI data available. Motherchild interactions were videotaped and systematically scored using the Maternal Behaviour Q-Sort (MBQS)-25 items, a standardized measure of maternal sensitivity. Linear mixed-effects models and logistic regression examined whether MBQS scores at 6 months predicted BMI at 48 months, controlling for other covariates. Results: After controlling for weight-relevant covariates, there was a significant sex by MBQS interaction (P = 0.015) in predicting 48 month BMI z. Further analysis revealed a strong negative association between MBQS scores and BMI in girls (P = 0.01) but not boys (P = 0.72). Logistic regression confirmed that in girls only, low maternal sensitivity was associated with the higher BMI categories as defined by the WHO (i.e. "at risk for overweight" or above). Conclusions: A significant association between low maternal sensitivity at 6 months of age and high body mass indices was found in girls but not boys at 48 months of age. These data suggest for the first time that the link between low maternal sensitivity and early BMI z may differ between boys and girls.

Infant cry is an adaptive signal of distress that elicits timely and mostly appropriate caring behaviors. Caregivers are typically able to decode the meaning of the cry and respond appropriately, but maladaptive caregiver responses are common and, in the worst cases, can lead to harmful events. To tackle the importance of studying cry patterns and caregivers’ responses, this review aims to identify key documents and thematic trends in the literature as well as existing research gaps. To do so, we conducted a scientometric review of 723 documents downloaded from Scopus and performed a document co-citation analysis. The most impactful publication was authored by Barr in 1990, which describes typical developmental patterns of infant cry. Six major research thematic clusters emerged from the analysis of the literature. Clusters were renamed “Neonatal Pain Analyzer” (average year of publication = 2002), “Abusive Head Trauma” (average year of publication = 2007), “Oxytocin” (average year ...

Experiencing maltreatment in early childhood predicts poor parasympathetic regulation, characterized by low baseline parasympathetic activity and strong withdrawal of parasympathetic influence in response to tasks. The Promoting First Relationships® (PFR) program improves parental sensitivity toward young children in families identified as maltreating. Using a subsample from a randomized control trial, we examined whether parental participation in PFR had lasting effects on toddlers' parasympathetic regulation, as measured by respiratory sinus arrhythmia (RSA), relative to a resource and referral control condition. In addition, we examined whether parental sensitive and responsive behavior mediated or moderated associations between parent treatment group and children's RSA. More than 6 months after completing treatment, 29 families in the PFR condition and 30 families in the control condition were visited at home, and toddlers' RSA was assessed at baseline and during 5 moderately challenging tasks. Groups did not differ in baseline RSA, but differed in RSA reactivity to the tasks. Across tasks, toddlers of parents in the control condition manifested significantly larger RSA decreases than toddlers of parents in the PFR condition. Parental behavior showed divergent associations with RSA change for toddlers of parents in the PFR versus control condition, with PFR treatment predicting RSA change ranging from small decreases to increases in toddlers of parents who showed the most sensitive, responsive behavior in the 6 months following treatment. This preliminary study showed that the same intervention that improved parenting also improved toddlers' parasympathetic regulation in response to everyday activities, warranting further experimental investigation.

Early biobehavioral regulation, a major influence of later adaptation, develops through dyadic interactions with caregivers. Thus, identification of maternal characteristics that can ameliorate or exacerbate infants’ innate vulnerabilities is key for infant well-being and long-term healthy development. The present study evaluated the influence of maternal parenting, postpartum psychopathology, history of childhood maltreatment, and demographic risk on infant behavioral and physiological (i.e., salivary cortisol) regulation using the still-face paradigm. Our sample included 153 women with high rates of childhood maltreatment experiences. Mother–infant dyads completed a multimethod assessment at 7 months of age. Structural equation modeling showed that maternal positive (i.e., sensitive, warm, engaged, and joyful) and negative (i.e., overcontrolling and hostile) behaviors during interactions were associated with concurrent maternal depressive symptoms, single parent status, and low fa...

Objective: Understanding the relationship between attachment and mental health has an important role in informing management of perinatal mental disorders and for infant mental health. It has been suggested that experiences of attachment are transmitted from one generation to the next. Maternal sensitivity has been proposed as a mediator, although findings have not been as strong as hypothesised. A meta-analysis suggested that this intergenerational transmission of attachment may vary across populations with lower concordance between parent and infant attachment classifications in clinical compared to community samples. However, no previous study has examined major depression and adult attachment in pregnancy as predictors of infant-parent attachment classification at 12 months postpartum. Methods: Data were obtained on 52 first-time mothers recruited in early pregnancy, which included 22 women who met diagnostic criteria for current major depression using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders. The Adult Attachment Interview was also administered before 20 weeks of pregnancy. A history of early trauma was measured using the Childhood Trauma Questionnaire and maternal sensitivity was measured at 6 months postpartum using the observational measure of the Emotional Availability Scales. Infant-parent attachment was measured using the Strange Situation Procedure at 12 months. Results: Overall, we found no significant association between the Adult Attachment Interview and the Strange Situation Procedure classifications. However, a combination of maternal non-autonomous attachment on the Adult Attachment Interview and major depression was a significant predictor of insecure attachment on the Strange Situation Procedure. We did not find that maternal sensitivity mediated parental and infant attachment security in this sample. While previous meta-analyses identified lower concordance in clinical samples, our findings suggest women with major depression and non-autonomous attachment have a greater concordance with insecure attachment on the Strange Situation Procedure. These findings can guide future research and suggest a focus on depression in pregnancy may be important for subsequent infant attachment.

Internal working models (IWMs) of attachment can moderate the effect of maternal depression on mother-child interactions and child development. Clinical depression predating birthgiving has been found to predict incoherent and less sensitive caregiving. Dysfunctional patterns observed, included interactive modes linked to feeding behaviors which may interfere with hunger-satiation, biological rhythms, and the establishment of children's autonomy and individuation. Feeding interactions between depressed mothers and their children seem to be characterized by repetitive interactive failures: children refuse food through oppositional behavior or negativity. The aim of this study was to investigate parenting skills in the context of feeding in mothers with major depression from the point of view of attachment theory. This perspective emphasizes parents' emotion, relational and affective history and personal resources. The sample consisted of 60 mother-child dyads. Mothers were divided into two groups: 30 with Major Depression and 30 without disorders. Children's age ranged between 12 and 36 months The measures employed were the Adult Attachment Interview and the Scale for the Evaluation of Alimentary Interactions between Mothers and Children. Insecure attachment prevailed in mothers with major depression, with differences on the Subjective Experience and State of Mind Scales. Groups also differed in maternal sensitivity, degrees of interactive conflicts and negative affective states, all of which can hinder the development of adequate interactive patterns during feeding. The results suggest that IWMs can constitute an indicator for the evaluation of the relational quality of the dyad and that evaluations of dyadic interactions should be considered when programming interventions.

Previous research has investigated the effect of maternal soothing behaviors on reducing infant reactivity but not the differential effects of specific maternal behaviors on infant stress responses. The present study investigated maternal regulation of 2-and 6-month-olds' responses to an inoculation and found a significant decline with age in both the intensity and duration of infants' crying. Maternal affection and touching decreased from 2 to 6 months, whereas maternal vocalizing and distraction behaviors increased. At both ages, the combination of maternal holding/rocking and vocalizing was associated with decreases in all levels of infant reactivity. Neither strategy alone, however, was found to be effective. Feeding/ pacifying behaviors were effective only when initial distress was at a low or moderate level, which suggests that the effectiveness of maternal regulatory behaviors may depend on the intensity of infants' crying.

Ample research links mothers' postpartum depression (PPD) to adverse interactions with their infants. However, most studies relied on general population samples, whereas a substantial number of women are at elevated depression risk. The purpose of this study was to describe mothers' interactions with their 6-and 12-month-old infants among women at elevated risk, although with a range of symptom severity. We also identified higher-order factors that best characterized the interactions and tested longitudinal consistency of these factors from 6 to 12 months of infant age. We leveraged data from eight projects across the United States (n = 647), using standardized depression measures and an adaptation of the NICHD Mother-Infant Interaction Scales. Overall, these depressionvulnerable mothers showed high levels of sensitivity and positive regard and low levels of intrusiveness, detachment, and negative regard with their infants. Factor analyses of maternal behaviors identified two overarching factors-"positive engagement" and "negative intrusiveness" that were comparable at 6 and 12 months of infant age. Mothers' ability to regulate depressed mood was a key behavior that defined "positive engagement" in factor loadings. An exceptionally strong loading of intrusiveness on the second factor suggested its central importance for women at elevated depression risk. Mothers with severe depressive symptoms had significantly more "negative intrusiveness" and less "positive engagement" with their 6-month-old infants than women with moderate or fewer depressive symptoms, suggesting a potential tipping point at which symptoms may interfere with the quality of care. Results provide the foundation for further research into predictors and moderators of women's interactions with their infant among women at elevated risk for PPD. They also indicate a need for evidence-based interventions that can support more severely depressed women in providing optimal care.

Significance Attachment disorganization is important to mental health, and is predicted by differences in caregiving. Still, not all children are equally influenced by such environmental factors. We examined whether differences in brain structures important to stress regulation influence the relation between maternal sensitive caregiving and levels of disorganization. We assessed brains at birth, as children are not yet exposed to substantial variation in parenting at this point in time. Our findings indicate that differences in the hippocampus, a structure important to conflict and stress, influence the association between caregiving and child outcomes. If replicated, this work may allow for more targeted interventions, and suggests the need to enhance fear regulation capabilities in infants likely to be exposed to lower quality caregiving.

Studies show that maternal behaviors are mediated by the bivariate serotonin transporter (5-HTT) genotype, although the findings are mixed, with some studies showing that mothers with the s allele exhibit increased maternal sensitivity, while other studies show that mothers with the s allele show decreased maternal sensitivity. Nonhuman primate studies offer increased control over extraneous variables and may contribute to a better understanding of the effects of the 5-HTT genotype on maternal sensitivity. This study assesses the influence of 5-HTT genotype variation on maternal sensitivity in parenting in 125 rhesus macaque mothers (Macaca mulatta) during the first three-months of their infants’ lives, an age well before typical infants undergo weaning. Mothers were genotyped for the 5-HTT genotype and maternal behaviors were collected, including neglectfulness, sensitivity, and premature rejections during undisturbed social interactions. Results showed that mothers homozygous for ...

Mothers were genotyped for the 5-HTT genotype and maternal behaviors were collected, including neglectfulness, sensitivity, and premature rejections during undisturbed social interactions. Results showed that mothers homozygous for the s allele rejected their infants the most and restrained their infants the least, an indication that mothers with the s allele are more likely to neglect their infants' psychological and physical needs. These findings suggest that, at an age when an infant's needs are based on warmth, security, and protection, mothers with an s allele exhibit less sensitive maternal behaviors. High rates of rejections and low rates of restraints are behaviors that typically characterize premature weaning and are inappropriate for their infant's young age. This study is an important step in understanding the etiology of variability in maternal warmth and care, and further suggests that maternal 5-HTT genotype should be examined in studies

Predictors of maternal sensitivity to infant distress were examined among 259 primiparous mothers. The Adult Attachment Interview, self-reports of personality and emotional functioning, and measures of physiological, emotional, and cognitive responses to videotapes of crying infants were administered prenatally. Maternal sensitivity was observed during three distress-eliciting tasks when infants were 6 months old. Coherence of mind was directly associated with higher maternal sensitivity to distress. Mothers' heightened emotional risk was indirectly associated with lower sensitivity via mothers' self-focused and negative processing of infant cry cues. Likewise, high physiological arousal accompanied by poor physiological regulation in response to infant crying was indirectly associated with lower maternal sensitivity to distress through mothers' selffocused and negative processing of infant cry cues. Maternal sensitivity to infant distress cues or during potentially distressing activities has been demonstrated to be predictive of infants' subsequent social-emotional adjustment, as indexed by infant-mother attachment security, better affective and physiological regulation, social competence, and the absence of behavioral problems, more so than has maternal sensitivity to infant non-distress (Conradt & Ablow

Infants are highly social and much of early learning takes place in a social context during interactions with caregivers. Previous research shows that social scaffolding – responsive parenting and joint attention - can confer benefits for infants’ long-term development and learning. However, little previous research has examined whether dynamic (moment-to-moment) adaptations in adults’ social scaffolding are able to produce immediate effects on childrens' performance. Here we ask whether infants' success on an object search task is more strongly influenced by dynamic changes in maternal responsive behaviour, or by fluctuations in infants' own internal motivation levels. Thirty-five mother-infant dyads (infants aged 10.8 months, on average) participated in an object search task that was delivered in a naturalistic manner by the child’s mother. Measures of maternal responsiveness (teaching duration; sensitivity) and infant motivation (engagement; visual attention) were ass...

Representaciones paternas del apego Representaciones de apego y sensitividad Discusión Referencias bibliográficas Anexos Anexo A: Consentimiento informado Anexo B: Ficha sociodemográfica Anexo C: Modificación de los enunciados del MBPQS para la aplicación en padres Anexo D: Tabla de diferencias en la sensitividad paterna y escalas del MBPQS según el género del hijo Anexo E: Diagrama de dispersión Seguridad -Sensitividad, Evitación -Sensitividad y Preocupación -Sensitividad La presente investigación tiene como objetivo establecer la relación entre las representaciones de apego y la sensitividad paterna en un grupo de padres de niños en edad preescolar. Para este propósito se evaluó a 18 padres con edades entre 25 y 50 años (M = 36, DE = 5.9) de niños con edades entre los 48 y 68 meses (M = 58, DE = 6.7) utilizando el Autocuestionario de Apego para Adultos "Modeles Individueles de Rélations" (CaMir) de Pierrehumbert, Karmaniola, Sieye, Meister, Miljkovitch y Halfonet (1996) para las representaciones de apego y la adaptación del Maternal Behavior for Preschoolers Q-Set de Posada, Moreno y Richmond (1998 en ) para el comportamiento sensitivo de los padres. Se encuentra que no hay diferencias significativas en la sensitividad de los padres en función a su representación de apego. Además, se tuvo como objetivo específico describir la sensitividad paterna, encontrando que los padres presentan un nivel global adecuado; sin embargo muestran menores niveles en relación a lo idealmente esperado en las áreas de Apoyo de base segura, Supervisión y Establecimiento de límites. Asimismo, se encontró que la edad del padre presenta una asociación inversa pero no significativa con la sensitividad de los mismos, pero sí se obtuvo una diferencia significativa en la sensitividad en función a si el padre se considera cuidador principal o no, y su estado de migración. Por otro lado, no se mostraron diferencias en la sensitividad respecto al género del hijo.

Maternal reflective functioning (RF) has been associated with quality of parent-child interactions and child development. This study investigated whether prenatal RF predicted the development of infant physical aggression and whether maternal sensitivity and/or intrusiveness mediated or moderated this association. The sample consisted of 96 first-time mothers (M = 22.57 years, SD = 2.13) and their infants (54 % male). Prenatal RF was measured with an interview, maternal behavior was observed during free play at 6 months post-partum, and infant physical aggression was assessed at 6, 12, and 20 months using maternal reports. Multivariate analyses of variance showed that relatively poor prenatal RF was related to relatively high infant physical aggression. These associations were moderated by maternal intrusiveness, with significant differences in physical aggression between RF-groups reportedly only in the absence of intrusiveness. Generally, mothers reported an increase in physical a...

Unstructured mother-toddler interactions were examined in 18-month-old high-and low-risk children subsequently diagnosed (n = 12) or not diagnosed (n = 21) with autism spectrum disorders (ASD) at 36 months. Differences in maternal sensitivity were not found as a function of emergent ASD status. A differentialsusceptibility moderation model of child risk guided investigations linking maternal sensitivity to child behavior and language growth. Group status moderated the relation between sensitivity and concurrent child behavior problems, with a positive association present for children with emergent ASD. Maternal sensitivity at 18 months predicted expressive language growth from age 2 to 3 years among children with emergent ASD only. Findings underscore the importance of understanding parent-child interaction during this key period in the development of autism symptomatology.

Being born small for gestational age (SGA) is considered a developmental vulnerability. Alternatively, SGA may be viewed as a marker for individual susceptibility to environmental experiences. The aim was to test if individuals born SGA are more susceptible to both negative and positive environmental experiences assessed by sensitive parenting in childhood compared with those born appropriate for gestational age (AGA). The target outcome was wealth in young adulthood. A total of 438 participants (SGA, n = 109; AGA, n = 329) were studied as part of the prospective Bavarian Longitudinal Study of neonatal at-risk children. Maternal sensitivity was observed during a standardized mother-child interaction task, and IQ was assessed with the Kaufman Assessment Battery for Children at age 6 years. At age 26, participants’ wealth was assessed with a comprehensive composite score. Individuals born SGA were found to be more susceptible to the effects of sensitive parenting after controlling for...

Neonatal risk factors have been associated with atypical development in various areas of social communication, including joint attention (JA), but little is known about factors in the early caregiving environment that can modify the negative implications of neonatal risk. The present study examines the links between neonatal risk and infants' JA, while considering the mediating role of maternal sensitive-responsiveness and the moderating roles of stressful contexts. One hundred and eighty-two families with infants (50% female) born in a wide range of gestational ages and birthweights participated in the study. Neonatal risk was assessed shortly after birth using three indicators: birthweight, gestational age, and degree of medical risk. At age 6 months, maternal sensitive-responsiveness to infants' foci of attention was rated and maternal anxiety and household chaos were measured. Infants' JA behaviors were assessed at age 12 months. A moderated-mediation model revealed that maternal anxiety symptoms and household chaos moderated the links between neonatal risk, maternal sensitive-responsiveness, and infants' responding to JA. Specifically, neonatal risk was related to less maternal sensitive-responsiveness only when maternal anxiety symptoms were above average levels, but not when anxiety symptoms were low. Moreover, maternal sensitive-responsiveness was positively related to infants' responding to JA behaviors when household chaos was low but not when it was high. These findings highlight the complex nature of the links between infants' early biological risk and caregiving environments in the development of social communication skills.

The current study examined the interaction between premature birth, temperamental reactivity, and parenting in early cognitive development. Participants were 142 infants (80 preterm; 62 full term) and their parents. Parent-child interactions (maternal, paternal, and co-parental) were observed at age 6 months to assess parental structuring behaviors. Additionally, both parents reported on infants' temperamental reactivity. At 12 months of age, infants' cognitive abilities were assessed. Consistent with the diathesis-stress model, preterm infants had lower cognitive outcomes than full-term infants when exposed to low levels of co-parental structuring, but functioned similarly when exposed to high levels of co-parental structuring. However, temperamental reactivity moderated this effect: Infants who carried one susceptibility factor (i.e., premature birth or reactive temperament) were similarly affected by co-parental structuring, whereas infants who carried two or no susceptibility factors were not. Furthermore, consistent with the differential susceptibility hypothesis, infants with highly reactive temperaments had lower cognitive functioning when exposed to low maternal structuring, but higher cognitive functioning when exposed to high maternal structuring compared to infants with lower reactivity. Results from this study highlight the importance of considering both temperamental reactivity and quality of parenting in understanding preterm infants' early cognitive vulnerability.

To date, research about feeding disorder (FD) has focused almost exclusively on the motherchild dyad, ignoring fathers' roles. The current study investigated father-child interactions with children having FD. The sample consisted of 67 children (1-3 years old) and their mothers and fathers. Thirty-four children, diagnosed with a nonorganic-based FD (FD group) and 33 children without an FD (control group) were matched for age, gender, birth order, and maternal education. Data were collected during home visits. Mothers were interviewed about their and the father's involvement in childcare. In addition, mother-child and father-child interactions were videotaped during play and feeding. Both mothers and fathers from the FD group experienced less positive parent-child interactions than did parents in the control group. Furthermore, mothers in the FD group reported greater maternal versus paternal childcare involvement than did control group mothers. Finally, FD group mothers exhibited more parental sensitivity than did fathers during feeing interactions; however, this difference was observed only when coupled with low paternal involvement. In families where fathers were highly involved, no difference was evident in paternal and maternal sensitivity. These findings highlight the importance of fathers' involvement, especially in families with children exhibiting an FD.

Antenatal and postnatal depression are independently associated with an increased risk of adverse infant development. A key linking mechanism is the quality of mother-infant interaction. Objectives: This study assesses the association between postnatal depressive symptoms (PDS) and their severity, with the quality of mother-infant interaction and compare the quality of mother-infant interaction and severity of the symptoms depending on the presence or absence of antenatal depressive symptoms (ADS). Methods: observational study in 177 psychosocial risk mother-infant dyads from Chile (infant aged 2-12 months). Results: Mothers with PDS had lower maternal sensitivity and a more intrusive/controlling style than mothers without PDS, although the severity of the symptoms was not associated with lower maternal sensitivity. Maternal sensitivity did not differ in the postnatal depressed mothers depending on the presence of ADS, although the mothers differed in interaction style and the severity of symptoms. Mothers with ADS and PDS presented with a predominant intrusive/controlling interaction style and more severe depressive symptoms, whereas those with only PDS presented with a predominant nonresponsive/passive interaction style and reduced severity of symptoms. The results corroborate the need to offer treatment and dyadic interventions to antenatal and postnatal depressive mothers and postulate that the presence of antenatal depressive symptoms may influence the subsequent mother-infant interaction style and greater severity of symptoms.

unlike studies on adolescent motherhood. Indeed, the role of adolescent and young fathers has rarely been investigated because, in most cases, these young fathers do not live with their children . However, the father's presence or absence affects both the mother's life and the child's growth . A small number of studies have shown that adolescent and young fathers are usually a few years older than adolescent mothers [5], and their main characteristics are similar to those of adolescent and young mothers in terms of risk factors . In particular, in most cases, young fathers come from disadvantaged socioeconomic backgrounds, exhibit premature sexual risk behaviors, and have adverse childhood experiences; frequently,

human faces compared to healthy matched peers. A significant association between neural response to social stimuli and infants' responsiveness to maternal stimulation during interactions is expected, with impoverished performances on the interactive domain in IUGR, compared to healthy peers. This study will enhance understanding on neural mechanisms underpinning the interactive patterns sustaining socio-cognitive development in IUGR and healthy infants. The study will help in clarifying the role of postnatal environment in buffering the vulnerability experienced by children delayed in their fetal growth.

The authors examined the associations between socioeconomic status (SES), race, maternal sensitivity, and maternal negative-intrusive behaviors and language development in a sample selected to reduce the typical confound between race and SES (n ϭ 146). Mother-child interactions were observed at 12 and 24 months (coded by randomly assigned African American and European American coders); language abilities were assessed at 18, 24, 30, and 36 months. For receptive language, race was associated with ability level, and maternal sensitivity and negative-intrusive parenting were related to rate of growth. For expressive communication, race, SES, and maternal sensitivity were associated with rate of growth; race moderated the association between negative-intrusive parenting and rate of growth such that the relation was weaker for African American than for European American children. The results highlight the importance of sensitive parenting and suggest that the association between negative-intrusive parenting and language development may depend upon family context. Future work is needed concerning the race differences found, including examining associations with other demographic factors and variations in language input experienced by children, using culturally and racially validated indices of language development.

Emerging research suggests that normative variation in parenting quality relates to children's brain development. However, although the young brain is presumed to be especially sensitive to environmental influence, to our knowledge only two studies have examined parenting quality with infants as it relates to indicators of brain development, and both were cross‐sectional. This longitudinal study investigated whether different components of maternal sensitivity in infancy predicted the volume of two brain structures presumed to be particularly sensitive to early experience, namely the amygdala and the hippocampus. Three dimensions of sensitivity (Cooperation/Attunement, Positivity, Accessibility/Availability) were observed in 33 mother–infant dyads at 1 year of age and children underwent structural magnetic resonance imaging at age 10. Higher maternal Accessibility/Availability during mother–infant interactions was found to be predictive of smaller right amygdala volume, while gr...

La infancia temprana es un periodo de gran relevancia en el desarrollo socioemocional infantil; de hecho, es donde se sientan las bases del desarrollo futuro. En este sentido, las adquisiciones durante el primer año de vida son predictores importantes de las habilidades sociales y emocionales futuras, de modo que la sensibilidad materna, según evidencia respecto a sus efectos en el desarrollo socioemocional del niño, ha demostrado ser un aspecto fundamental durante este periodo. Teniendo esto en cuenta, y considerando la relevancia de dicha competencia, así como el alza mundial y nacional en las tasas de cesárea y los posibles riesgos asociados al tipo de parto vivenciado, el presente estudio tuvo como objetivo analizar la influencia dela sensibilidad materna y del tipo de parto en el desarrollo socioemocional infantil al año de edad. Para ello, se estudió una muestra no probabilística intencionada de 91 madres con sus respectivos hijos o hijas de distinto nivel socioeconómico que a...

ABSTRACTThe current study evaluated the effectiveness of a home‐based psychotherapeutic Infant Mental Health Home Visiting (IMH‐HV) intervention for enhancing parenting sensitivity; a secondary aim was to evaluate whether the use of video feedback was associated with greater treatment response. Participants were N = 78 mothers and their children (age at entry ranged from prebirth to 24‐month old (M = 9.8, SD = 8.4), who were initiating IMH‐HV services with community mental health‐based therapists (N = 51). Dyads were assessed during extended home visits via standardized interviews and observational and questionnaire methods within the first month of treatment (baseline), and again 6 and 12 months thereafter. Following each of these extended home visits, study evaluators completed a standard Q‐sort to capture observations of maternal sensitivity during the visit. Therapists completed fidelity checklists used to derive the total number of IMH‐HV sessions received (i.e., dosage) and fr...

In this article, we test the hypothesis that beliefs about the ideal mother are convergent across cultures and that these beliefs overlap considerably with attachment theory’s notion of the sensitive mother. In a sample including 26 cultural groups from 15 countries around the globe, 751 mothers sorted the Maternal Behavior Q-Set to reflect their ideas about the ideal mother. The results show strong convergence between maternal beliefs about the ideal mother and attachment theory’s description of the sensitive mother across groups. Cultural group membership significantly predicted variations in maternal sensitivity belief scores, but this effect was substantially accounted for by group variations in socio-demographic factors. Mothers living in rural versus urban areas, with a low family income, and with more children, were less likely to describe the ideal mother as highly sensitive. Cultural group membership did remain a significant predictor of variations in maternal sensitivity b...

This study examined the effects of prenatal cocaine exposure on infant hypothalamic-pituitaryadrenal axis activity and reactivity at 7 months of infant age. Participants were 168 caregiver-infant dyads (87 cocaine exposed, 81 not cocaine exposed; 47% boys). Maternal behavior, caregiving instability, and infant growth and behavior were assessed, and children's saliva was sampled before, during, and after standardized procedures designed to elicit emotional arousal. Results revealed cocaine-exposed infants had a high amplitude trajectory of cortisol reactivity compared to noncocaine-exposed infants. Infant gender and caregiving instability moderated this association. The findings support a dual hazard vulnerability model and have implications for evolutionarydevelopmental theories of individual differences in biological sensitivity to context.

This study evaluated prospective longitudinal relations among an index of poverty-related cumulative risk, maternal salivary cortisol, child negative affect, and maternal sensitivity across the first two postpartum years. Participants included 1,180 biological mothers residing in rural and predominantly low-income communities in the US. Multilevel growth curve analyses indicated that an index of cumulative risk was positively associated with maternal cortisol across the postpartum (study visits occurring at approximately 7, 15, and 24 months postpartum) over and above effects for African American ethnicity, time of day of saliva collection, age, parity status, having given birth to another child, contraceptive use, tobacco smoking, body mass index, and breastfeeding. Consistent with a psychobiological theory of mothering, maternal salivary cortisol was negatively associated with maternal sensitivity observed during parent-child interactions across the first two postpartum years over and above effects for poverty-related cumulative risk, child negative affect, as well as a large number of covariates associated with cortisol and maternal sensitivity. Child negative affect expressed during parent-child interactions was negatively associated with observed maternal sensitivity at late (24 months) but not early time points of observation (7 months) and cumulative risk was negatively associated with maternal sensitivity across the postpartum and this effect strengthened over time. Results advance our understanding of
