Mary Ainsworth’s legacy: a systematic review of observational instruments measuring parental sensitivity

Child-father and child-mother attachment relationships in naturalistic settings

This study examines paternal and maternal sensitivity as predictors of toddlers' attachment security in two naturalistic contexts. Seventy-three mostly White middle-class families participated between 2015 and 2019 when children (49.3% girls) were approximately 29.48 months old. Each child-parent dyad completed a home and playground visit. Findings revealed paternal and maternal sensitivity were significantly associated at home and marginally at the playground. Paternal sensitivity was only predictive of security to the father at the playground, showing a medium effect, while small effects of maternal sensitivity on security to the mother were found in both contexts. Cross-parent contributions to security were small and limited to the playground. The need to consider the greater ecology of child-parent relationships and suggestions for larger-scale research are discussed.

Parental sensitivity and family conversation: A naturalistic longitudinal study with both mothers and fathers across three time-points in early infancy

Parental verbal sensitivity is known to promote child language skills, but few studies have considered: (a) links between global (i.e., verbal, behavioral, and affective) measures of parental sensitivity and infant-initiated conversations, an important precursor to language development; (b) whether maternal and paternal sensitivity show similar links with infant-initiated conversation; or (c) the transactional role of infant conversation for later parental sensitivity. Addressing these gaps, this study of 186 British first-time parents (93 families) examines the developmental dynamics between parental sensitivity and infant communication across the first year of life. We explore; (i) the role of maternal and paternal sensitivity (assessed during structured home observations at 4 months post-partum) for parent-infant conversational interactions at 7 months (indexed by day-long naturalistic recordings), and (ii) whether these mother-infant and father-infant conversations at 7 months shape maternal and paternal sensitivity at 14 months (also assessed via structured home observations). For both male and female infants, maternal (but not paternal) sensitivity at 4 months predicted infant vocalisations and conversational initiation at 7-months. By contrast, neither index of infant talk predicted maternal or paternal sensitivity at 14 months. Together these findings refine understanding of theoretical models of social development and suggest new possibilities for future research.

Identifying vulnerable mother-infant dyads: a psychometric evaluation of two observational coding systems using varying interaction periods

Introduction

Clinical services require feasible assessments of parent-infant interaction in order to identify dyads requiring parenting intervention. We assessed the reliability and predictive validity of two observational tools and tested whether briefer forms could be identified which retain acceptable psychometric properties over short observation periods.

Methods

A stratified high-risk community sample of 250 mother-infant dyads from The Wirral Child Health and Development Study completed 7-min play-based interaction at 6-8 months. Film-footage was independently coded by two trained raters using PIIOS and NICHD-SECCYD systems. Incremental predictive validity was assessed from 3, 5 and 7 min observation to attachment outcomes (Strange Situation; 14 months) and infant mental health (BITSEA; 14 and 30 months).

Results

Excellent inter-rater reliability was evident at code and subscale level for each tool and observation period. Stability of within-rater agreement was optimal after 5 min observation. ROC analysis confirmed predictive (discriminant) validity (AUCs >0.70) to top decile age 2 mental health outcomes for PIIOS total score and a brief 3-item composite from NICHD-SECCYD (sensitivity, intrusiveness, positive regard; NICHD-3), but not to attachment outcomes. Logistic regression showed dyads rated at-risk for externalizing problems using NICHD-3 were also at significantly higher risk for insecurity at 14 months (OR = 2.7, p = 0.004).

Conclusion

PIIOS total and NICHD-3 ratings from 5 min observation are both reliable and valid tools for use in clinical practice. Findings suggest NICHD-3 may have greater utility due to its comparative brevity to train and code, with suitability for use over a broader developmental time frame (3-24 months).

Maternal sensitivity and child internalizing and externalizing behavior: a mediating role for glucocorticoid receptor gene (NR3C1) methylation?

The early caregiving environment can have lasting effects on child mental health. Animal models suggest that glucocorticoid receptor gene (NR3C1) DNA methylation plays a mediating role in linking more responsive caregiving to improved behavioral outcomes by its impact on the stress regulatory system. In this longitudinal study, we examined whether children's NR3C1 methylation levels mediate an effect of maternal sensitivity in infancy on levels of child internalizing and externalizing behavior in a community sample. Maternal sensitivity of 145 mothers was rated at infant age 5 weeks, 12 months, and 30 months by observing mother-infant interactions. Buccal DNA methylation was assessed in the same children at age 6 years and maternal-reported internalizing and externalizing behavior was assessed at age 6 and 10 years. Higher sensitivity at age 5 weeks significantly predicted lower DNA methylation levels at two NR3C1 CpG loci, although methylation levels at these loci did not mediate an effect of maternal sensitivity on levels of child internalizing and externalizing behavior. Overall, the study provides evidence that maternal sensitivity in early infancy is associated with DNA methylation levels at loci involved in stress regulation, but the significance of this finding for child mental health remains unclear.

Annual Research Review: Early intervention viewed through the lens of developmental neuroscience

The overarching goal of this paper is to examine the efficacy of early intervention when viewed through the lens of developmental neuroscience. We begin by briefly summarizing neural development from conception through the first few postnatal years. We emphasize the role of experience during the postnatal period, and consistent with decades of research on critical periods, we argue that experience can represent both a period of opportunity and a period of vulnerability. Because plasticity is at the heart of early intervention, we next turn our attention to the efficacy of early intervention drawing from two distinct literatures: early intervention services for children growing up in disadvantaged environments, and children at elevated likelihood of developing a neurodevelopmental delay or disorder. In the case of the former, we single out interventions that target caregiving and in the case of the latter, we highlight recent work on autism. A consistent theme throughout our review is a discussion of how early intervention is embedded in the developing brain. We conclude our article by discussing the implications our review has for policy, and we then offer recommendations for future research.

The concept analysis of parent-infant bonding during pregnancy and infancy: a systematic review and meta-synthesis

INTRODUCTION

Despite the emerging body of literature on mother-to-infant bonding and the associated variables, there are various definitions of bonding construct. Also, there is a lack of a comprehensive conceptual framework of antecedents and consequences of bonding that would guide empirical work.

OBJECTIVE

Aim of the study was to provide a systematic review and synthesis of concept analysis studies on maternal-foetal, mother-infant, or father-infant bonding.

METHOD

A systematic search was performed in PubMed, EBSCOHost (including PsycINFO), ProQuest, and CINAHL. In addition, a hand search was conducted. Papers were eligible for inclusion if they conducted concept analyses on mother or father to foetus/infant bonding. A qualitative meta-synthesis was applied to synthesise the findings.

RESULTS

Eight papers on concept analyses were eligible for inclusion. In meta-synthesis, six aspects of parent-to-(unborn) child bonding emerged, including direction, domain, process, timing, endurance, and parental gender. Defining attributes are (i) a close relationship, (ii) filled with positive parental affection, (iii) manifested during pregnancy as monitoring foetal development and behaviour and after childbirth in proximity and interaction. Antecedents, affecting factors, and consequences of the parent-child bonding have been summarised.

CONCLUSION

Parent-infant bonding refers to an emotional, behavioural, cognitive, and neurobiological tie of the parent to the (unborn) child, as a process from intention to have a child throughout infancy. This is a parental-driven process which can continue to evolve throughout child's and parent's life, characterised as enduring, committed, and engaged. Based on meta-synthesis, a conceptual structure of parent-infant bonding has been provided, which needs further empirical testing.

Testing reliability and validity of practitioner-rated parental sensitivity: A novel tool for practice

Improving parental sensitivity is an important objective of interventions to support families. This study examined reliability and validity of parental sensitivity ratings using a novel package of an e-learning tool and an interactive decision tree provided through a mobile application, called the OK! package. Independent raters assessed parental sensitivity using the OK! package (N = 11 raters) and the NICHD Parental Sensitivity rating scales (N = 22 raters) on the basis of videotaped mother-child interactions at 10- or 12-months-old (N = 294) and at 24-months-old (N = 204) from the Dutch longitudinal cohort study Generation2 . Mothers reported on children's externalizing and internalizing problems and social competence when children were 4 and 7 years old. Results showed excellent single interrater reliability for raters using the OK! package (mean ICC = .79), and strong evidence for convergent validity at 10- or 12-month-old (r = .57) and 24-month-old (r = .65). Prospective associations of neither parental sensitivity rated using the OK! package or the NICHD Parental Sensitivity rating scales with child developmental outcomes were statistically significant (p > .05), with overlapping 95% confidence intervals for both measures. The OK! package provides a promising direction for testing alternatives to current training and instruction modalities.

Stress and emotion recognition predict the relationship between a history of maltreatment and sensitive parenting behaviors: A moderated-moderation

Our study proposes to examine how stress and emotion recognition interact with a history of maltreatment to influence sensitive parenting behaviors. A sample of 58 mothers and their children aged between 2 and 5 years old were recruited. Parents' history of maltreatment was measured using the Child Trauma Questionnaire. An emotion recognition task was performed. Mothers identified the dominant emotion in morphed facial emotion expressions in children. Mothers and children interacted for 15 minutes. Salivary cortisol levels of mothers were collected before and after the interaction. Maternal sensitive behaviors were coded during the interaction using the Coding Interactive Behavior scheme. Results indicate that the severity of childhood maltreatment is related to less sensitive behaviors for mothers with average to good abilities in emotion recognition and lower to average increases in cortisol levels following an interaction with their children. For mothers with higher cortisol levels, there is no association between a history of maltreatment and sensitive behaviors, indicating that higher stress reactivity could act as a protective factor. Our study highlights the complex interaction between individual characteristics and environmental factors when it comes to parenting. These results argue for targeted interventions that address personal trauma.

Coding Dyadic Behavior in Caregiver-Child Interaction from a Clinical Psychology Perspective: How Should Multiple Instruments and Outcomes Be Dealt with?

The experiences children have in the interactions with their caregivers influence their developmental outcomes. To target caregiving and optimize intervention effects, the assessment of caregiver-child interactions is highly relevant for families affected by parental mental disorders. Behavioral observation is a widely used method for assessing family dynamics, and the literature offers a wide variety of instruments with which to code such data. However, a structured overview of behavioral observation instruments (BOIs) is lacking, and the multitude of types of dyadic behaviors (DBs) assessed within each BOI are complicating their application. We aim to provide an overview of the BOIs applied to families affected by mental disorders and suggest a DB taxonomy that may be used across BOIs. We first conducted a systemic literature search to identify the most frequently used BOIs and the DBs they capture in clinical psychology. Second, we asked 13 experts to sort DB terms based on perceived conceptual similarity and analyzed these results using multidimensional scaling. We found approximately 450 different terms for DBs, and we argue that DBs can be classified within two overarching dimensions, i.e., in terms of structure and in terms of reaction to a child's signals. These efforts can facilitate the coding and application of BOIs in clinical practice.

Parental sensitivity modifies the associations between maternal prenatal stress exposure, autonomic nervous system functioning and infant temperament in a diverse, low-income sample

Evidence suggests that adversity experienced during fetal development may shape infant physiologic functioning and temperament. Parental sensitivity is associated with child stress regulation and may act as a buffer against risk for intergenerational health effects of pre- or postnatal adversity. Building upon prior evidence in a racially and ethnically diverse sample of infants (M infant age = 6.5 months) and women of low socioeconomic status, this study examined whether coded parenting sensitivity moderated the association between an objective measure of prenatal stress exposures (Stressful Life Events (SLE)) and infant parasympathetic (respiratory sinus arrhythmia; RSA) or sympathetic (pre-ejection period; PEP) nervous system functioning assessed during administration of the Still-Face-Paradigm (SFP) (n = 66), as well as maternal report of temperament (n = 154). Results showed that parental sensitivity moderated the associations between prenatal stress exposures and infant RSA reactivity, RSA recovery, PEP recovery, and temperamental negativity. Findings indicate that greater parental sensitivity is associated with lower infant autonomic nervous system reactivity and greater recovery from challenge. Results support the hypothesis that parental sensitivity buffers infants from the risk of prenatal stress exposure associations with offspring cross-system physiologic reactivity and regulation, potentially shaping trajectories of health and development and promoting resilience.

Comparison of mothers' perceptions of hunger cues in 3-month-old infant under different feeding methods

BACKGROUND

Mothers' perception of infant hunger cues is a critical content of responsive feeding, which is central to the promotion of early childhood development. However, only a few studies have examined responsive feeding in China, especially lacking the studies on perceptions of infant hunger cues. Consider the cultural differences, the aim of this study was to describe the perceptions of infant hunger cues of Chinese mothers for infants aged 3 months, and explore the relationship between maternal perceptions of infant hunger cues and different feeding methods.

METHODS

A cross-sectional study was conducted with a sample of 326 mothers of healthy 3-month-old infants, including 188 exclusive breastfeeding (EBF) mothers and 138 formula feeding (FF) mothers. It was implemented in four provincial and municipal maternal and child health hospitals. The mothers' perceptions of infant hunger cues were surveyed by self-reporting questionnaires. Chi-square tests and logistic analysis were applied to analyze the differences in maternal perceptions of infant hunger cues, including the number of hunger cues and the specific cues, between EBF group and FF group by controlling sociodemographic variables and the daily nursing indicators.

RESULTS

We found that a higher proportion of EBF mothers could perceive multiple hunger cues (≥ 2) than FF mothers (66.5% vs.55.1%). For specific cues, the EBF mothers had higher perceptions of infant's "hand sucking" (67.6% vs. 53.6%) and "moving head frantically from side to side" (34.6% vs. 23.9%), all p < 0.05. Regression analysis revealed that EBF might support mothers to perceive infant hunger cues than FF mothers, with the number of infant hunger cues (OR = 1.70, 95% CI: 1.01-2.85), "hand sucking" (OR = 1.72, 95% CI: 1.04-2.87), "moving head frantically from side to side" (OR = 2.07, 95% CI: 1.19-3.62). The number of infant hunger cues perceived by mothers was also associated with their educational level and family structure.

CONCLUSION

EBF mothers of 3-month-old infants may be more likely to perceive infant hunger cues than FF mothers in China. It is necessary to increase the health education about infant hunger and satiety cues to caregivers in China, especially among mothers with lower education levels, mothers living in nuclear families, and FF mothers.

Instruments to measure interaction of mothers and newborns: A systematic review

Interactions between newborns and their parents/primary caregivers are characterized by asymmetric and dependent relationships. This systematic review mapped, identified, and described the psychometric parameters, categories, and items of instruments used to assess mother-newborn interaction. Seven electronic databases were accessed in this study. Furthermore, this research included neonatal interaction studies describing instruments' items, domains, and psychometric properties while excluding studies that focused on maternal interactions and lacked items for assessing newborns. Additionally, studies validated with older infants that did not have a newborn in the sample were used for test validation, which is a criterion used to decrease the risk of bias. Fourteen observational instruments from 1047 identified citations were included that addressed interactions using varying techniques, constructs, and settings. Particularly, we focused on observational settings that assessed interactions with communication-based constructs in the context of proximity or distance as influenced by physical, behavioral, or procedural barriers. These tools are also used to predict risk behaviors in a psychological context, mitigate feeding difficulties, and conduct neurobehavioral assessments of mother-newborn interactions. The elicited imitation was also an observational setting. This study found that the most described properties in the included citations were inter-rater reliability followed by criterion validity. However, only two instruments reported content, construct, and criterion validity, as well as a description of an internal consistency assessment and inter-rater reliability. Finally, the synthesis of the instruments reported in this study can guide clinicians and researchers in selecting the most appropriate one for their own application.

Compliance or empathy-What links maternal sensitivity and toddlers' emotional helping?

Emotional helping-that is, helping based on others' emotional distress-has been suggested to be a central prosocial response to others in need. Developmental theorizing proposed that emotional helping has social origins. Whereas research indeed demonstrated a link between maternal sensitivity and children's emotional helping, developmental theories stress different mediating processes. Emotion-sharing theories claim empathic concern to be the crucial link for helping, whereas internalization theories base children's helping on children's compliance. To investigate these hypotheses, the current study explored empathy and compliance as two possible mediators for the relation between maternal sensitivity and children's emotional helping at 18 months of age. Overall, maternal sensitivity was positively related to children's empathy, children's compliance, and children's emotional helping. Interestingly, children's empathy-but not children's compliance-mediated the link between maternal sensitivity and children's emotional helping. These findings deepen our understanding of the psychological processes subserving emotional helping during infancy and support theories that stress the socioemotional origins of children's prosocial behavior.

Warmth and reciprocity with mothers, and young children's resilience to exposure to community violence in Colombia: findings from the La Sabana Parent-Child Study

BACKGROUND

Exposure to community violence is common worldwide and is associated with emotional and behavioural problems in children. Little is known about sources of resilience. Building on our previous work on the contribution of callous-unemotional (CU) traits to child aggression in Colombia, we examined whether positive parenting is protective for children whose families are exposed to community violence.

METHODS

Families were recruited from three demographically contrasting regions of Colombia. The sample comprised 235 children aged 3.5 years and their mothers, of whom 220 (93%) were followed up at age 5.0 years. Positive parenting was assessed as the average of maternal warmth and reciprocity, and as praise, and negative parenting as the average of negative affect and conflict seen in video recordings of standardized procedures. CU traits and oppositional defiant disorder were assessed by maternal report at ages 3.5 and 5.0 years, and mothers reported exposure to community violence over the 18 months between assessments. A range of potential confounds was included in adjusted analyses.

RESULTS

In the families who were exposed to community violence, but not in the unexposed, maternal warmth and reciprocity were associated prospectively with lower CU traits (interaction, p = .007). In the exposed group maternal warmth and reciprocity explained 10% of the variance (β = -.34, p = .001). Maternal praise was not associated with CU traits. Maternal negative parenting predicted higher CU traits as the main effect but not in interaction with community violence exposure.

CONCLUSIONS

Maternal warmth and reciprocity with young children may promote resilience in the face of community violence. Programmes to enhance these protective processes may be needed especially where prospects for reducing community violence are limited. The centrality of parents for these children highlights the plight of those exposed to community violence, and also either separated from parents or orphaned.
