Annual Research Review: Parenting and children's brain development: the end of the beginning

Neural response to monetary and social rewards in adolescent girls and their parents

Functional magnetic resonance imaging (fMRI) studies have indicated that the mesocorticolimbic dopamine system is heavily involved in all stages of reward processing. However, the majority of research has been conducted using monetary rewards and it is unclear to what extent other types of rewards, such as social rewards, evoke similar or different neural activation. There have also been few investigations into potential differences or similarities between reward processing in parents and offspring. The present study examined fMRI neural activation in response to monetary and social reward in a sample of 14-22-year-old adolescent girls (N = 145) and a biological parent (N = 124) and compared activation across adolescent-parent dyads (N = 82). Across all participants, both monetary and social reward elicited bilateral striatal activation, which did not differ between reward types or between adolescents and their parents. Neural activation in response to the different reward types were positively correlated in the striatum among adolescents and in the mPFC and OFC among parents. Overall, the present study suggests that both monetary and social reward elicit striatal activation regardless of age and provides evidence that neural mechanisms underlying reward processing may converge differentially among youth and adults.

Parental impact during and after neonatal intensive care admission

Parents play a pivotal role in neurodevelopmental outcomes of their children in the neonatal intensive care unit (NICU) and beyond. Integration of parents in clinical care and research is synergistic. Engaged parents yield more comprehensive clinical care and more robust and meaningful research products. Subsequently, successful clinical and research efforts improve outcomes for children. We review strategies for parental integration into NICU clinical care and research, including parental involvement in therapeutic interventions and neurodevelopmental care, and effective communication strategies for clinicians and researchers. We discuss challenges in neonatal trials and emphasize the need for building a culture of research, collaborative partnerships with patient advocacy organizations, and ongoing support beyond the NICU. Overall, we call for recognizing and fostering the impactful role of parents as teammates with clinicians and researchers in optimizing neurodevelopmental outcomes in the NICU and beyond.

All in the Family? A Systematic Review and Meta-analysis of Parenting and Family Environment as Risk Factors for Attention-Deficit/Hyperactivity Disorder (ADHD) in Children

Parenting and family environment have significant impact on child development, including development of executive function, attention, and self-regulation, and may affect the risk of developmental disorders including attention-deficit/hyperactivity disorder (ADHD). This paper examines the relationship of parenting and family environment factors with ADHD. A systematic review of the literature was conducted in 2014 and identified 52 longitudinal studies. A follow-up search in 2021 identified 7 additional articles, for a total of 59 studies that examined the association of parenting factors with ADHD outcomes: ADHD overall (diagnosis or symptoms), ADHD diagnosis specifically, or presence of the specific ADHD symptoms of inattention and hyperactivity/impulsivity. For parenting factors that were present in three or more studies, pooled effect sizes were calculated separately for dichotomous or continuous ADHD outcomes, accounting for each study's conditional variance. Factors with sufficient information for analysis were parenting interaction quality (sensitivity/warmth, intrusiveness/reactivity, and negativity/harsh discipline), maltreatment (general maltreatment and physical abuse), parental relationship status (divorce, single parenting), parental incarceration, and child media exposure. All factors showed a significant direct association with ADHD outcomes, except sensitivity/warmth which had an inverse association. Parenting factors predicted diagnosis and overall symptoms as well as inattentive and hyperactive symptoms when measured, but multiple factors showed significant heterogeneity across studies. These findings support the possibility that parenting and family environment influences ADHD symptoms and may affect a child's likelihood of being diagnosed with ADHD. Prevention strategies that support parents, such as decreasing parenting challenges and increasing access to parent training in behavior management, may improve children's long-term developmental health.

A Holistic Approach to Early Relational Health: Cultivating Culture, Diversity, and Equity

Early Relational Health (ERH) is the foundation for infant and child emotional and social wellbeing. ERH is a quality of relationships co-created by infants, caregivers, and other members of their families and communities from pregnancy through childhood. Relationships themselves are not ERH; rather, ERH can be a feature of relationships. Those that are characterized by positive, shared emotionality become contexts within which members co-develop mutual capacities that enable them to prevail and flourish. This essay offers a synthesis of current knowledge about ERH in the US and begins to integrate Indigenous and non-Indigenous research and knowledge about ERH in the hope that readers will embrace "Etuaptmumk"-"Two-Eyed Seeing". The authors maintain that systems of care for infants, families, and their communities must first and foremost attend to revitalization, cultural context, diversity, equity, and inclusion. Authors discuss key concepts in ERH; Indigenous and non-Indigenous research that inform ERH; structural and systemic factors in the US that affect ERH ecosystems; the critical intersections of culture, diversity, equity; the broader concept of village support for fostering ERH; and efforts to revitalize ERH discourse, practices, and policies. The authors advocate for a holistic approach to ERH and suggest future directions for research and advocacy.

Parenting by mothers from marginalized communities and the role of socioeconomic disadvantage: insights from marginalized Roma communities in Slovakia

Background

Roma living in marginalized communities often face poor living conditions and material deprivation, which may negatively impact parenting. Our aim is to compare the parenting behavior (support, harsh discipline, and stimulation) of mothers from marginalized Roma communities and the majority population in Slovakia. We also examine the role of socioeconomic disadvantage and related worries in the differences in parenting behavior between these groups.

Methods

We obtained cross-sectional data from mothers of children aged 14-18 months using the first wave of the longitudinal RomaREACH study dataset. Two groups were included in the sample: 93 mothers from MRCs and 102 mothers from the majority. We performed multiple regression and mediation analyses to assess whether the educational level of mothers, the degree of poverty, and poverty-related feelings of stress and worries explain parenting behavior differences between the groups of mothers.

Results

We found significant differences in parenting, especially in harsh disciplining and stimulation. These two domains were significantly associated with maternal education, degree of poverty, and poverty-related stress and worries. The degree of poverty partially mediated stimulation differences between the two groups of mothers.

Conclusion

Parenting in MRCs seems harsher and less stimulative than parenting in the Slovak majority. These differences are associated with the socioeconomic disadvantage of mothers. The degree of poverty partially explains why parenting in MRCs is less stimulative. These results may inform intervention efforts aimed at disadvantaged families.

A sex-specific pathway linking early life maltreatment, vagal activity, and depressive symptoms

Background: Experiences of early life maltreatment (ELM) are alarmingly common and represent a risk factor for the development of psychopathology, particularly depression. Research has focused on alterations in autonomic nervous system (ANS) functioning as a mediator of negative mental health outcomes associated with ELM. Early alterations in autonomic vagal activity (vmHRV) may moderate the relationship between ELM and depression, particularly when considering forms of emotional maltreatment. Recent evidence suggests that the relationships of both ELM and vmHRV with depression may be non-linear, particularly considering females.Objective: Building on and extending theoretical considerations and previous work, the present work aims to further the current understanding of the complex relationships between ELM exposure, vmHRV, and depression.Methods: This study uses an adaptive modelling approach, combining exploratory network-based analyses with linear and quadratic moderation analyses, drawing on a large sample of males and females across adolescence (total N = 213; outpatient at-risk sample and healthy controls) and adulthood (total N = 85; community-based convenience sample).Results: Exploratory network-based analyses reveal that exposure to emotional abuse is particularly central within a network of ELM subtypes, depressive symptoms, and concurrent vmHRV in both adolescents and adults. In adults, emotional neglect shows strong associations with both emotional abuse and vmHRV and is highly central as a network node, which is not observed in adolescents. Moderator analyses reveal significant interactions between emotional maltreatment and vmHRV predicting depressive symptoms in adult females. Significant quadratic relationships of emotional maltreatment and vmHRV with depression are observed in both adolescent and adult females.Conclusions: The present findings contribute to the understanding of the psychological and physiological mechanisms by which ELM acts as a risk factor for the development of depression. Ultimately, this will contribute to the development of targeted and effective intervention strategies to mitigate the detrimental effects of early adversity.

Lower maternal emotional availability is related to increased attention toward fearful faces during infancy

It has been suggested that infants' age-typical attention biases for faces and facial expressions have an inherent connection with the parent-infant interaction. However, only a few previous studies have addressed this topic. To investigate the association between maternal caregiving behaviors and an infant's attention for emotional faces, 149 mother-infant dyads were assessed when the infants were 8 months. Caregiving behaviors were observed during free-play interactions and coded using the Emotional Availability Scales. The composite score of four parental dimensions, that are sensitivity, structuring, non-intrusiveness, and non-hostility, was used in the analyses. Attention disengagement from faces was measured using eye tracking and face-distractor paradigm with neutral, happy, and fearful faces and scrambled-face control pictures as stimuli. The main finding was that lower maternal emotional availability was related to an infant's higher attention to fearful faces (p = .042), when infant sex and maternal age, education, and concurrent depressive and anxiety symptoms were controlled. This finding indicates that low maternal emotional availability may sensitize infants' emotion processing system for the signals of fear at least during this specific age around 8 months. The significance of the increased attention toward fearful faces during infancy is an important topic for future research.

Parental Deprivation- and Threat-Based Factors Associated with Youth Emotion-Based Neurocircuitry and Externalizing Behavior: A Systematic Review

Parental factors, including negative parenting practices (e.g., family conflict, low monitoring), parental depression, and parental substance use, are associated with externalizing behaviors among youth. However, the ways in which these parental factors are associated with youth brain function and consequent externalizing behavior has been less studied. Both the dimensional and stress acceleration models provide frameworks for understanding how parental factors may be associated with frontolimbic and frontoparietal networks implicated in emotional attention and regulation processes. The current review builds upon this work by examining how deprivation- and threat-based parental factors are associated with youth neurocircuitry involved in emotional functioning and externalizing behaviors. A systematic review using PRISMA guidelines was completed and included five studies assessing parenting behaviors, six studies assessing parental depressive symptoms and/or diagnosis, and 12 studies assessing parental history of substance use. Synthesis of reviewed studies discusses support for the dimensional and stress acceleration models within the context of deprivation and threat. Further, a limited number of studies tested (i.e., six studies) and supported (i.e., three studies) youth neural structure and function as a mediator of the association between parental factors and youth externalizing behavior. Specific recommendations for future work include more deliberate planning related to sample composition, improved clarity related to parental constructs, consistency in methodology, and longitudinal study design in order to better understand associations between contextual parental influences and youth neural and behavioral functioning.

Parenting Influences on Frontal Lobe Gray Matter and Preterm Toddlers' Problem-Solving Skills

Children born preterm often face challenges with self-regulation during toddlerhood. This study examined the relationship between prematurity, supportive parent behaviors, frontal lobe gray matter volume (GMV), and emotion regulation (ER) among toddlers during a parent-assisted, increasingly complex problem-solving task, validated for this age range. Data were collected from preterm toddlers (n = 57) ages 15-30 months corrected for prematurity and their primary caregivers. MRI data were collected during toddlers' natural sleep. The sample contained three gestational groups: 22-27 weeks (extremely preterm; EPT), 28-33 weeks (very preterm; VPT), and 34-36 weeks (late preterm; LPT). Older toddlers became more compliant as the Tool Task increased in difficulty, but this pattern varied by gestational group. Engagement was highest for LPT toddlers, for older toddlers, and for the easiest task condition. Parents did not differentiate their support depending on task difficulty or their child's age or gestational group. Older children had greater frontal lobe GMV, and for EPT toddlers only, more parent support was related to larger right frontal lobe GMV. We found that parent support had the greatest impact on high birth risk (≤27 gestational weeks) toddler brain development, thus early parent interventions may normalize preterm child neurodevelopment and have lasting impacts.

Parental emotionality is related to preschool children's neural responses to emotional faces

The ability to accurately decode others' facial expressions is essential for successful social interaction. Previous theories suggest that aspects of parental emotionality-the frequency, persistence and intensity of parents' own emotions-can influence children's emotion perception. Through a combination of mechanisms, parental emotionality may shape how children's brains specialize to respond to emotional expressions, but empirical data are lacking. The present study provides a direct empirical test of the relation between the intensity, persistence and frequency of parents' own emotions and children's neural responses to perceiving emotional expressions. Event-related potentials (ERPs) were recorded as typically developing 3- to 5-year-old children (final Ns = 59 and 50) passively viewed faces expressing different emotional valences (happy, angry and fearful) at full and reduced intensity (100% intense expression and 40% intense expression). We examined relations between parental emotionality and children's mean amplitude ERP N170 and negative central responses. The findings demonstrate a clear relation between parental emotionality and children's neural responses (in the N170 mean amplitude and latency) to emotional expressions and suggest that parents may influence children's emotion-processing neural circuitry.

Early emotional caregiving environment and associations with memory performance and hippocampal volume in adolescents with prenatal drug exposure

Early adversities, including prenatal drug exposure (PDE) and a negative postnatal emotional caregiving environment, impact children's long-term development. The protracted developmental course of memory and its underlying neural systems offer a valuable framework for understanding the longitudinal associations of pre- and postnatal factors on children with PDE. This study longitudinally examines memory and hippocampal development in 69 parent-child dyads to investigate how the early caregiving emotional environment affects children with PDE's neural and cognitive systems. Measures of physical health, drug exposure, caregiver stress, depression, and distress were collected between 0 and 24 months At age 14 years, adolescents completed multiple measures of episodic memory, and at ages 14 and 18 years, adolescents underwent magnetic resonance imaging (MRI) scans. Latent constructs of episodic memory and the caregiving environment were created using Confirmatory Factor Analysis. Multiple regressions revealed a negative emotional caregiving environment during infancy was associated with poor memory performance and smaller left hippocampal volumes at 14 years. Better memory performance at 14 years predicted larger right hippocampal volume at 18 years. At 18 years, the association between the emotional caregiving environment and hippocampal volume was moderated by sex, such that a negative emotional caregiving environment was associated with larger left hippocampal volumes in males but not females. Findings suggest that the postnatal caregiving environment may modulate the effects of PDE across development, influencing neurocognitive development.

Longitudinal Associations from Maternal and Paternal Internalizing Symptoms to Preschooler's Problem Behavior and Social Competence in China: The Mediating Role of Executive Function

By using a two-year longitudinal design, the current study recruited 199 preschoolers and their parents in Beijing to examine the effects of parental internalizing symptoms (T1) on children's internalizing and externalizing problem behavior and social competence (T3), and further explore whether executive function (EF, T2) may act as the mediator. The results showed that maternal internalizing symptoms and paternal internalizing symptoms at T1 separately had significant direct predictive effect on children's internalizing and externalizing problem behavior but not on social competence at T3 after controlling family socioeconomic status. Further analysis indicated that children's inhibitory self-control at T2 mediated the association between maternal and paternal internalizing symptoms at T1 and children's externalizing problem behavior at T3, and metacognition at T2 could mediate the influence of maternal internalizing symptoms at T1 on children's internalizing problem behavior, externalizing problem behavior and social competence at T3. These findings to some extent highlight the importance of including both parents and exploring mother-father differences in effective interventions aiming to promoting child development. Metacognition and self-control skill training would be helpful to reduce children's problem behavior or to improve their social competence.

Associations between parental depression and anxiety symptom severity and their Offspring's cortical thickness and subcortical volume

Depression and anxiety are associated with grey matter changes in subcortical regions in adults and adolescents. Parent psychopathology is associated with offspring brain structure, but it's unclear whether altered brain structure in children is associated with severity of parental depression and anxiety symptoms. We examined 123 youth (Mean age = 13.64; 62% female) with no clinically significant history of depression or anxiety and one parent diagnosed with current or past depressive or anxiety disorders. Parents completed the Mini International Neuropsychiatric Interview to assess diagnostic status and the Beck Depression Inventory-II, and the Generalized Anxiety Disorder-7 to assess current symptom severity. Youth underwent T1 weighted structural Magnetic Resonance Imaging scans. Bivariate analyses revealed higher parental depressive severity was not significantly associated with offspring grey matter. Parental anxiety severity was significantly associated with less left global surface area. When controlling for offspring age, sex and intracranial volume (ICV), offspring right surface area was negatively associated with parental depressive severity at a trend level. In previously depressed parents, greater parental depressive severity was significantly associated with offspring decreased left and right surface area. There were no significant associations between parental anxiety severity in previously depressed parents and offspring subcortical or cortical brain regions. These results highlight associations between parental depressive symptom severity and offspring brain structure and suggest that even within an already high-risk group of adolescents, there may be altered cortical surface area depending on parent symptom severity. This may help identify youth most at risk for developing a mood disorder and could help further early intervention and identification efforts.

Associations between childhood irritability and neural reactivity to maternal feedback in adolescence

Early irritability, a transdiagnostic vulnerability for psychopathology, is associated with alterations in neural reactivity to emotional stimuli and reward; however, associations between childhood irritability and neural markers of risk may be mitigated by the quality of caregiving youth receive. We examined longitudinal relationships between irritability in childhood and young adolescents' neural activity of regions typically associated with emotion regulation and reward processing during processing of maternal feedback and tested whether these associations were moderated by youth's perceptions of the parent-child relationship quality. Eighty-one adolescents (Mage = 11.1 years) listened to maternal critical and praising feedback while undergoing functional magnetic resonance imaging. Age 3 irritability, assessed observationally, was negatively associated with age 11 neural reactivity to maternal criticism in a cluster in the right dorsolateral prefrontal cortex (dlPFC), particularly for youths who reported more positive maternal parenting. Given the role of the dlPFC activation in the effortful processing of emotional stimuli, decreased activation may reflect disengagement from negatively valenced interpersonal feedback in the context of a positive caregiving environment, thereby mitigating psychopathology risk associated with irritability.

Association between Electronic Media Use and Internalizing Problems: The Mediating Effect of Parent-Child Conflict and Moderating Effect of Children's Age

In today's digital world, children are exposed extensively to electronic media, making it an integral part of their daily lives. However, excessive use of electronic media during childhood has been associated with various internalizing problems. Moreover, parent-child conflict and children's age may be closely associated with children's problem behaviors. The current study employed a cross-sectional design and conducted a questionnaire survey of 711 parents to examine the association between children's electronic media use and their internalizing problems. Furthermore, this study probed the mediating role of parent-child conflict within this association and the moderating effect of children's age. The results of structural equation modeling showed a positive correlation between children's use of electronic media and their internalizing difficulties. Parent-child conflict served as a mediating factor in this association. Results also showed that the association between parent-child conflict and internalizing problems becomes more pronounced as children grow older. These findings imply that parents should encourage their children to develop healthy habits in using electronic media while fostering positive relationships. Parents should also be mindful of the psychological changes as children age and provide guidance to help them become proficient digital citizens.

Observed Parenting and Adolescent Brain Structure

Parent-youth relationships and parenting are critically important to adolescents' development. The present study examined associations between parenting behaviors (which included observed parent emotion expression and negative and positive parenting behaviors during a parent-adolescent interaction) and adolescent brain structure, and sex differences in associations, in 66 12-14 year-olds. The study found that 1) among all adolescents in the sample, greater parent negative emotion expression in parent-youth interactions was associated with greater adolescent gray matter volume (GMV) in the left hippocampus, 2) parent positive emotion expression was not associated with adolescent GMV, 3) several associations differed by sex. These findings suggest that parenting is important for adolescent brain structure and future work should consider this by sex.

Prospective associations between maternal mind-mindedness, child theory of mind, and brain morphology in school-aged children

Mentalizing is defined as the ability to attribute mental states to oneself and others. In the context of parental behavior, parents' tendency to comment on their child's mental activities refers to the concept of mind-mindedness (MM). MM has been positively associated with various developmental outcomes in children, notably their own ability to mentalize, known as theory of mind (ToM). Although parental (MM) and child (ToM) mentalizing have important implications during childhood, their associations with children's neural structures are largely unknown. Among 62 mother-child dyads, maternal MM was rated from free-play sequences when children were aged 1 year, child ToM was assessed using a first-order false-belief task at 4 years of age, and structural MRI images were acquired at 10 years of age. Maternal MM was positively associated with gray matter volumes (GMV) in the dorsal prefrontal cortex and the superior temporal pole. Child ToM abilities were positively associated with GMV in the ventromedial prefrontal cortex. Though cortical regions associated with MM and ToM showed no anatomical overlap, many are functionally connected through a neural network highly involved in self-referential strategies for mentalizing. These findings suggest that MM and ToM may contribute to distinct sub-processes that collectively support social cognition development.

General and Specific Factors of Environmental Stress and Their Associations With Brain Structure and Dimensions of Psychopathology

Background

Early-life stressors can adversely affect the developing brain. While hierarchical modeling has established the existence of a general factor of psychopathology, no studies have modeled a general factor of environmental stress and related this factor to brain development. Using a large sample of children from the ABCD (Adolescent Brain Cognitive Development) Study, the current study aimed to identify general and specific factors of environmental stress and test their associations with brain structure and psychopathology.

Methods

In a sample of 11,878 children, bifactor modeling and higher-order (second-order) modeling identified general and specific factors of environmental stress: family dynamics, interpersonal support, neighborhood socioeconomic status deprivation, and urbanicity. Structural equation modeling was performed to examine associations between these factors and regional gray matter volume (GMV) and cortical thickness as well as general and specific factors of psychopathology.

Results

The general environmental stress factor was associated with globally smaller cortical and subcortical GMV as well as thinner cortices across widespread regions. Family dynamics and neighborhood socioeconomic status deprivation were associated with smaller GMV in focal regions. Urbanicity was associated with larger cortical and subcortical GMV and thicker cortices in frontotemporal regions. The environmental factors were associated with psychopathology in the expected directions. The general factors of environmental stress and psychopathology were both predictors of smaller GMV in children, while remaining distinct from each other.

Conclusions

This study reveals a unifying model of environmental influences that illustrates the inherent organization of environmental stressors and their relationship to brain structure and psychopathology.

What predicts persisting social impairment following pediatric traumatic brain injury: contribution of a biopsychosocial approach

BACKGROUND

Psychosocial deficits, such as emotional, behavioral and social problems, reflect the most common and disabling consequences of pediatric traumatic brain injury (TBI). Their causes and recovery likely differ from physical and cognitive skills, due to disruption to developing brain networks and the influence of the child's environment. Despite increasing recognition of post-injury behavioral and social problems, there exists a paucity of research regarding the incidence of social impairment, and factors predicting risk and resilience in the social domain over time since injury.

METHODS

Using a prospective, longitudinal design, and a bio-psychosocial framework, we studied children with TBI (n = 107) at baseline (pre-injury function), 6 months, 1 and 2-years post-injury. We assessed intellectual ability, attention/executive function, social cognition, social communication and socio-emotional function. Children underwent structural magnetic resonance imaging (MRI) at 2-8 weeks post-injury. Parents rated their child's socio-emotional function and their own mental health, family function and perceived burden.

RESULTS

We distinguished five social recovery profiles, characterized by a complex interplay between environment and pre- and post-TBI factors, with injury factors playing a lesser role. Resilience in social competence was linked to intact family and parent function, intact pre-injury adaptive abilities, post-TBI cognition and social participation. Vulnerability in the social domain was related to poor pre- and post-injury adaptive abilities, greater behavioral concerns, and poorer pre- and post-injury parent health and family function.

CONCLUSIONS

We identified five distinct social recovery trajectories post-child-TBI, each characterized by a unique biopsychosocial profile, highlighting the importance of comprehensive social assessment and understanding of factors contributing to social impairment, to target resources and interventions to children at highest risk.

Parenting Styles and Psychological Resilience: The Mediating Role of Error Monitoring

Parenting styles are associated with children's psychological resilience. However, the underlying mechanisms of this have not been investigated. Parenting styles influence how individuals respond to self-inflicted errors, and error monitoring is related to psychological resilience. Therefore, this study proposed that error monitoring might be a bridging factor between parenting styles and psychological resilience. Seventy-two young healthy adults were recruited for this study. Parenting styles were assessed using the Parental Bonding Instrument, and psychological resilience was measured using the Connor-Davidson Resilience Scale. Error monitoring was investigated in the Flanker task using event-related potentials (ERPs), and two error-related components of ERPs were measured: error-related negativity (ERN) and error positivity. Mediation analyses showed that the ERN partially mediated the relationship between parenting styles and psychological resilience. Specifically, a higher level of self-reported parental overprotection was related to larger ERN amplitude, which in turn was associated with lower psychological resilience. Additionally, a higher level of self-reported parental allowance of autonomy was related to lower ERN amplitude, which in turn was linked to higher psychological resilience. These results suggest that shaping children's sensitivity in early automatic error detection is one possible mechanism through which parental styles influence their psychological resilience.

The Role of Neural Self-Referential Processes Underlying Self-Concept in Adolescent Depression: A Comprehensive Review and Proposed Neurobehavioral Model

There is growing knowledge about how self-concept develops in adolescence and contributes to the onset of depression, but researchers have only recently begun investigating the neural mechanisms that underlie self-referential cognition in adolescents with and without depression. This paper reviews task-related functional neuroimaging (fMRI) research on self-referential neural processing in both healthy and depressed adolescents (M_age range = 12-18 years), with a focus on elucidating brain activation that may subserve adolescent self-perception and related associations with depression. Drawing on conclusions from the affective neuroscience literature and developmental theory, we propose a neurobehavioral model and future research recommendations to address how social factors might shape self-referential neural processes and self-concept in ways that confer risk for depression. We review the operationalization of self-concept, developmental theory (i.e., symbolic interactionism) on self-concept development, and the role of self-concept in adolescent depression. We then review empirical studies assessing neural activation during healthy and depressed adolescents' processing of self-relevant information, and the limited studies assessing links between social factors and neural self-referential processing.

History of "Serve and Return" and a Synthesis of the Literature on its Impacts on Children's Health and Development

Parent/caregiver sensitivity and responsiveness are important for children's health and development. The "serve and return" metaphor was created to help providers and caregivers understand the importance of sensitive and responsive early caregiving. In this review, we explain the concept of "serve and return", outline historical and theoretical principles that culminated in this metaphor, highlight parent and child constructs associated with "serve and return" interactions, and synthesize literature on sensitive and responsive caregiving and children's health and developmental outcomes. Nurses and other healthcare professionals in public policy, clinical, community, education, and research roles need knowledge of "serve and return" interactions.

Editorial: Using parenting interventions as treatments and brain development - are we at the end of the beginning yet?

This editorial discusses where we stand in understanding how parenting interventions, frequently used in the treatment of child emotional and behavioral disorders, affect the brain systems that contribute to these disorders. It concludes that although we have some evidence from RCTs that improving adverse parenting causally impacts some aspects of brain development, there is almost nothing examining parenting randomized controlled trials to treat child clinical disorders and effects on brain structure or function. It argues that if we are to be a brain science, such studies are needed.

Morphometric dis-similarity between cortical and subcortical areas underlies cognitive function and psychiatric symptomatology: a preadolescence study from ABCD

Preadolescence is a critical period characterized by dramatic morphological changes and accelerated cortico-subcortical development. Moreover, the coordinated development of cortical and subcortical regions underlies the emerging cognitive functions during this period. Deviations in this maturational coordination may underlie various psychiatric disorders that begin during preadolescence, but to date these deviations remain largely uncharted. We constructed a comprehensive whole-brain morphometric similarity network (MSN) from 17 neuroimaging modalities in a large preadolescence sample (N = 8908) from Adolescent Brain Cognitive Development (ABCD) study and investigated its association with 10 cognitive subscales and 27 psychiatric subscales or diagnoses. Based on the MSNs, each brain was clustered into five modules with distinct cytoarchitecture and evolutionary relevance. While morphometric correlation was positive within modules, it was negative between modules, especially between isocortical and paralimbic/subcortical modules; this developmental dissimilarity was genetically linked to synapse and neurogenesis. The cortico-subcortical dissimilarity becomes more pronounced longitudinally in healthy children, reflecting developmental differentiation of segregated cytoarchitectonic areas. Higher cortico-subcortical dissimilarity (between the isocortical and paralimbic/subcortical modules) were related to better cognitive performance. In comparison, children with poor modular differentiation between cortex and subcortex displayed higher burden of externalizing and internalizing symptoms. These results highlighted cortical-subcortical morphometric dissimilarity as a dynamic maturational marker of cognitive and psychiatric status during the preadolescent stage and provided insights into brain development.

Longitudinal associations between mother-child attachment security in toddlerhood and white matter microstructure in late childhood: a preliminary investigation

Early childhood experiences are considered to influence the strength and effectiveness of neural connections and thus the development of brain connectivity. As one of the most pervasive and potent early relational experiences, parent-child attachment is a prime candidate to account for experience-driven differences in brain development. Yet, knowledge of the effects of parent-child attachment on brain structure in typically developing children is scarce and largely limited to grey matter, whereas caregiving influences on white matter (i.e. neural connections) have seldom been explored. This study examined whether normative variation in mother-child attachment security predicts white matter microstructure in late childhood and explored associations with cognitive-inhibition. Mother-child attachment security was assessed using home observations when children (N = 32, 20 girls) were 15 and 26 months old. White matter microstructure was assessed using diffusion magnetic resonance imaging when children were 10 years old. Child cognitive-inhibition was tested when children were 11 years old. Results revealed a negative association between mother-toddler attachment security and child white matter microstructure organization, which in turn related to better child cognitive-inhibition. While preliminary given the sample size, these findings add to the growing literature that suggests that rich and positive experiences are likely to decelerate brain development.

Correlates for Suicidality Among At-risk Youth Receiving Community-Based Mental Health Services

"At-risk" adolescents are at high risk of unsuccessfully transitioning into adulthood and are also at elevated risk for suicidal behavior. Though much research has been conducted on risk factors for suicidality among the general adolescent population, research on suicidality among "at-risk" adolescents is lacking. This is a notable gap in the literature given that "at-risk" adolescents may be three times more likely to exhibit suicidality. The present study addressed this research gap by examining correlates for suicidality among "at-risk" adolescents receiving mental health services in the community. Using Electronic Health Record (EHR) data, risk factors for suicidality were analyzed at the bivariate and multivariate levels. Sexual abuse was a significant predictor of suicidality, as well as impulsivity for suicide attempt only. These findings may serve as useful adjuncts in the design of suicidality-screening tools and follow-up practices within the context of community-based mental health organizations which target at-risk adolescents.

Poverty from fetal life onward and child brain morphology

Poverty is a risk factor for impaired child development, an association possibly mediated by brain morphology. Previous studies lacked prospective poverty assessments during pregnancy and did not stratify by majority/minority status. We investigated the association of household poverty from fetal life forward with brain morphological differences at age 10 years, in 2166 mother-child dyads. Overall, the results showed no associations between any poverty exposure early in life and brain volumes. However, there was the evidence of timing effects: children exposed to poverty in utero had smaller amygdala volumes (B =  - 0.18, 95%CI - 0.30; - 0.07, pFDR-adjusted = 0.009). There were also differences in associations by majority/minority status (cerebral white matter: p for interaction = 0.04). Dutch children exposed to childhood poverty showed smaller cerebral white matter volumes than their control (B =  - 0.26, 95%CI - 0.45; - 0.06, pFDR-adjusted = 0.035). This association was not observed in the minority population (B =  - 0.05, 95%CI - 0.23; 0.12, pFDR-adjusted = 0.542). The smaller cerebral white matter volume mediated the association between childhood poverty and poorer school performance in Dutch children. Our findings point to the importance of poverty exposure in the fetal period and suggest different mechanisms and vulnerabilities across majority/minority groups.

Resilience mediates parenting style associated school bullying victimization in Chinese children and adolescents

BACKGROUND

Existing evidence has shown that negative parenting style elevates the risk of school bullying victimization in children and adolescents. Resilience may play as a mediating factor in this association. However, this hypothesis has not been investigated.

METHODS

In this cross-sectional study, a total of 4582 Chinese children and adolescents had been surveyed by self-administered questionnaire. The Chinese version of Egna Minnen av. Barndoms Uppfostra (s-EMBU-C), the Olweus Bully/Victim Questionnaire (OBVQ) and the Resilience Scale for Chinese Adolescents (RSCA) were used to collect relevant information. Univariate and multiple logistic regression models were used to estimate the crude and adjusted associations between parenting style, resilience, and bullying victimization. Path analysis was used to estimate the mediation via resilience in the association between parenting style and bullying victimization.

RESULTS

After adjustment for possible covariates, the results of multivariate binary logistic regression model suggested that among all dimensions of parenting style, mother's and father's rejection were significantly associated with school bullying victimization. Path analysis revealed a statistically significant mediation of resilience in the association between parental rejection and bullying victimization, and among the five dimensions of resilience, emotion regulation, family support and interpersonal assistance accounted for the highest proportions of mediation.

CONCLUSIONS

For children and adolescents who suffered from parental rejection, building up resilience, especially those measures aiming at improving emotion regulation ability and consolidating family and peer support, might be effective in reducing risk of school bullying victimization.

Development of cognitive control during adolescence: The integrative effects of family socioeconomic status and parenting behaviors

Cognitive control is of great interest to researchers and practitioners. The concurrent association between family socioeconomic status (SES) and adolescent cognitive control is well-documented. However, little is known about whether and how SES relates to individual differences in the development of adolescent cognitive control. The current four-year longitudinal investigation (N = 167, 13-14 years at Wave 1) used multi-source interference task performance (reaction time in interference correct trials minus neutral correct trials) and corresponding neural activities (blood oxygen level dependent contrast of interference versus neutral conditions) as measures of cognitive control. SES and parenting behaviors (warmth, monitoring) were measured through surveys. We examined direct and indirect effects of earlier SES on the development of cognitive control via parenting behaviors; the moderating effect of parenting also was explored. Results of latent growth modeling (LGM) revealed significant interactive effects between SES and parenting predicting behavioral and neural measures of cognitive control. Lower family SES was associated with poorer cognitive performance when coupled with low parental warmth. In contrast, higher family SES was associated with greater improvement in performance, as well as a higher intercept and steeper decrease in frontoparietal activation over time, when coupled with high parental monitoring. These findings extend prior cross-sectional evidence to show the moderating effect of the parenting environment on the potential effects of SES on developmental changes in adolescent cognitive control.

Cortisol Reactivity and Observed Parenting among Mothers of Children with and without ADHD

OBJECTIVE

Neurobiological models suggest links between maternal cortisol reactivity and parenting; however, no studies have examined cortisol reactivity and parenting in mothers of school-age children with ADHD.

METHOD

We examined the relationship between observed parenting and maternal cortisol reactivity in two laboratory contexts: the Trier Social Stress Task (TSST) and parenting-child interaction (PCI). Mothers of children with (N = 24) and without (N = 36) ADHD participated.

RESULTS

During the TSST, greater cortisol output and increase were associated with decreased positive and increased negative parenting. However, during the PCI, cortisol output was associated with increased self-reported and observed positive parenting, and decreased observed negative parenting. Cortisol change during the PCI was associated with decreased observed positive parenting and increased self-reported negative parenting. Among mothers of children with ADHD, cortisol output during the PCI was negatively associated with negative, inconsistent parenting. Change in cortisol predicted more inconsistent discipline and corporal punishment.

CONCLUSION

Findings contribute to an integrative biological, psychological, and cognitive process model of parenting in families of children with ADHD.

Understanding Associations Between Race/Ethnicity, Experiences of Discrimination, and Psychotic-like Experiences in Middle Childhood

OBJECTIVE

The present study aimed to examine factors that may account for race/ethnicity differences in psychotic-like experiences (PLEs) in a middle childhood sample, including evidence for experiences of discrimination as a psychosocial mediator of these differences.

METHOD

In a sample of 9- to 10-year-olds (N = 10,839) from the Adolescent Brain Cognitive Development Study, we compared PLEs across racial/ethnic groups. We also examined whether experiences of discrimination indirectly linked racial/ethnic identity and PLEs and whether social support moderated this indirect association.

RESULTS

Differences between racial/ethnic groups were found in the endorsement of PLEs, such that Black and Hispanic participants endorsed higher levels of PLEs compared with Asian, multiracial/multiethnic, and White participants. These differences were accounted for in part by experiences of discrimination, an indirect effect that was in turn attenuated by increased social support.

CONCLUSION

This is the first study to suggest that the experience of discrimination may indirectly link the association between racial/ethnic differences and endorsement of PLEs using the Prodromal Questionnaire-Brief Child Version and additionally that social support may act as a moderator of this mediation. Results provide evidence that social inequities such as racial discrimination may contribute to increases in PLEs. These findings shed further light on the links between structural racism and mental health inequities for people in minoritized groups.

Effects of Parental Internalizing and Externalizing Behavior Problems on Children’s Limbic Brain Structures—An MRI Study

Parental behavior problems have long-term effects on children’s limbic brain structures and functions. Parental behavior problems-related brain changes in children may lead to mental disorders and behavior dysfunction later in life. However, our understanding of the relationship between parental behavior and children’s brain structures is less obvious when children and adolescents are studied in a general population without mental disorders. The majority of studies on the relationship between parental behavior and adolescent brain structure have been focused on severe forms of the following parental behavior problems: (1) internalizing behavior associated with mood and anxiety disorders, and (2) externalizing behavior associated with substance use and violence. A few studies examined the effect of normative variations or subtle differences in parental behavior. Therefore, we utilized a large study—Adolescent Brain Cognitive Development (ABCD)—to determine relationships between normative variation in parental internalizing and externalizing behavior and limbic brain structures in children and adolescents without mental disorders. Quantile (median) regression models were used to compute associations between parental behavior and children’s limbic structures. We found that parental internalizing and externalizing behaviors are uniquely associated with children’s limbic structures after adjustment for biological confounders and parental socioeconomic status. Our findings indicate that normative parental behavior may have a significant early influence on limbic structures of normally developing children and adolescents. Accelerated or delayed limbic structure maturation may account for children’s and adolescents’ behavioral inadequacies and a risk of developing specific mood disorders or substance abuse problems later in life.

Maternal sensitivity at the age of 8 months associates with local connectivity of the medial prefrontal cortex in children at 5 years of age

The quality of mother–child interaction, especially maternal sensitivity in caregiving behavior, plays an important role in a child’s later socioemotional development. Numerous studies have indicated associations between poor mother–child interaction and offspring brain structure and function, but more knowledge on how variation in the characteristics of early caregiving is associated with children’s brain structure and function is needed. We investigated whether maternal sensitivity at 8 or 30 months is associated with functional connectivity in a child’s brain at 5 years of age based on the FinnBrain Birth Cohort Study (17 and 39 mother–child dyads at 8 and 30 months, respectively, with an overlap of 13 dyads). Maternal sensitivity was assessed during a free play interaction using the Emotional Availability Scales at 8 and 30 months of the children’s age. Task-free functional magnetic resonance imaging (fMRI) was acquired at the age of 5 years in 7-min scans while watching the Inscapes movie. Regional homogeneity (ReHo) maps were created from the fMRI data, and multiple regression analysis was performed to assess the relation between maternal sensitivity and ReHo. Maternal sensitivity at the age of 8 months was positively associated with children’s ReHo values within the medial prefrontal cortex. Distal connectivity of this region showed no significant association with maternal sensitivity in a seed-based connectivity analysis. No associations were found between maternal sensitivity during toddlerhood and brain functional connectivity. Together, these results suggest that maternal sensitivity, especially in infancy, may influence offspring brain functional connectivity. However, studies with larger sample sizes are warranted.

Maternal warmth is associated with network segregation across late childhood: A longitudinal neuroimaging study

The negative impact of adverse experiences in childhood on neurodevelopment is well documented. Less attention however has been given to the impact of variations in “normative” parenting behaviors. The influence of these parenting behaviors is likely to be marked during periods of rapid brain reorganization, such as late childhood. The aim of the current study was to investigate associations between normative parenting behaviors and the development of structural brain networks across late childhood. Data were collected from a longitudinal sample of 114 mother-child dyads (54% female children, M age 8.41 years, SD = 0.32 years), recruited from low socioeconomic areas of Melbourne, Australia. At the first assessment parenting behaviors were coded from two lab-based interaction tasks and structural magnetic resonance imaging (MRI) scans of the children were performed. At the second assessment, approximately 18 months later (M age 9.97 years, SD = 0.37 years) MRI scans were repeated. Cortical thickness (CT) was extracted from T1-weighted images using FreeSurfer. Structural covariance (SC) networks were constructed from partial correlations of CT estimates between brain regions and estimates of network efficiency and modularity were obtained for each time point. The change in these network measures, from Time 1 to Time 2, was also calculated. At Time 2, less positive maternal affective behavior was associated with higher modularity (more segregated networks), while negative maternal affective behavior was not related. No support was found for an association between local or global efficacy and maternal affective behaviors at Time 2. Similarly, no support was demonstrated for associations between maternal affective behaviors and change in network efficiency and modularity, from Time 1 to Time 2. These results indicate that normative variations in parenting may influence the development of structural brain networks in late childhood and extend current knowledge about environmental influences on structural connectivity in a developmental context.

Disorganized attachment behaviors in infancy as predictors of brain morphology and peer rejection in late childhood

Studies show robust links between disorganized attachment in infancy and socioemotional maladjustment in childhood. Little is known, however, about the links between disorganized attachment and brain development, and whether attachment-related differences in brain morphology translate into meaningful variations in child socioemotional functioning. This study examined the links between infants' disorganized attachment behaviors toward their mothers, whole-brain regional grey matter volume and thickness, and peer rejection in late childhood. Thirty-three children and their mothers took part in this study. The Strange Situation Procedure was used to assess mother-infant attachment when infants were 18 months old. Magnetic resonance imaging was performed when they were 10 years old to assess cortical thickness and grey matter volumes. Children and teachers reported on peer rejection 1 year later, as an indicator of socioemotional maladjustment. Results indicated that disorganized attachment was not associated with grey matter volumes. However, children who exhibited more disorganized attachment behaviors in infancy had significantly thicker cortices in bilateral middle and superior frontal gyri, and extending to the inferior frontal gyrus, as well as the orbitofrontal and insular cortices in the right hemisphere in late childhood. Moreover, children with thicker cortices in these regions experienced greater peer rejection, as rated by themselves and their teachers. Although preliminary, these results are the first to indicate that disorganized attachment may play a role in cortical thickness development and that changes in cortical thickness are associated with differences in child socioemotional functioning.

Caregivers’ Responses to Children’s Negative Emotions: Associations with Preschoolers’ Executive Functioning

There is a lack of knowledge regarding the connection between parental emotional responsiveness and children’s executive functioning (EF). This study aimed to explore the relations between caregivers’ reactions to their children’s distress and children’s EF. Mothers of 136 preschoolers reported their reactions to their children’s negative emotions using the Coping with Children’s Negative Emotions Scale. Children’s EF was assessed through the mothers and teachers’ reports using the Behavioral Inventory of Executive Functioning for Preschool Children. Results showed that the mothers’ perceived use of negative emotional regulation responses (i.e., punitive and minimizing reactions) was associated with lower levels of EF in children, as reported by both mothers and teachers. The association between the mothers’ use of positive emotional regulation responses (i.e., problem-focused, emotion-focused, and expressive encouragement reactions) and children’s EF was not significant. Multiple regression analyses revealed that the mothers’ use of negative emotional regulation responses accounted for significant proportions of variance in EF indexes. These findings suggest that parental socialization of emotion could be important for children’s EF. Specifically, caregivers’ negative emotional regulation responses to children’s distress may serve as a risk factor for poorer EF in children. Efforts to improve children’s EF may be more effective when parental emotional responsiveness to their distress is considered.

Interpersonal Family Dynamics Relate to Hippocampal CA Subfield Structure

Social environments that are extremely enriched or adverse can influence hippocampal volume. Though most individuals experience social environments that fall somewhere in between these extremes, substantially less is known about the influence of normative variation in social environments on hippocampal structure. Here, we examined whether hippocampal volume tracks normative variation in interpersonal family dynamics in 7- to 12-year-olds and adults recruited from the general population. We focused on interpersonal family dynamics as a prominent feature of one's social world. Given evidence that CA1 and CA2 play a key role in tracking social information, we related individual hippocampal subfield volumes to interpersonal family dynamics. More positive perceptions of interpersonal family dynamics were associated with greater CA1 and CA2/3 volume regardless of age and controlling for socioeconomic status. These data suggest that CA subfields are sensitive to normative variation in social environments and identify interpersonal family dynamics as an impactful environmental feature.

Early Physiotherapy Intervention Program for Preterm Infants and Parents: A Randomized, Single-Blind Clinical Trial

Background: The early developmental interventions might be designed with a preventative approach to improving the development of at-risk preterm infants. The present study aimed to evaluate the effectiveness of an early physiotherapy intervention on preterm infants’ motor and global development, and on parents’ stress index. Methods: 48 infants were enrolled and randomized into two groups. Infants allocated to the intervention group received an early physiotherapy intervention, based on parental education sessions and tactile and kinesthetic stimulation during the NICU period, as well as a home-based activity program. The intervention commenced after 32 weeks post-menstrual age and ended at 2 months corrected age. Infants allocated to the control group received the usual care based on the NIDCAP-care. Results: No differences were found between groups on the Alberta Infant Motor Scale at 2- or 8-months corrected age. Infants in the intervention group showed more optimal fine motor, problem-solving, personal-social, and communication development at 1 month corrected age. Conclusions: The results showed no effect on the early physiotherapy intervention. Results might be related to the dose or intensity of the intervention, but also to the poor parental compliance.

Maternal Responsive Parenting Trajectories From Birth to Age 3 and Children's Self-Esteem at First Grade

This paper examines the quality and stability of the responsive parenting practices of mothers with infants and the longitudinal links between these practices and children’s self-esteem. Using data presented by the Panel Study on Korean Children, this study identified Korean mothers’ responsive parenting trajectories from birth to age three and examined their associations with children’s self-esteem at first grade. Korean mothers developed one of three responsive parenting patterns from birth to age three: low (19.0%), moderate (66.0%), or high (15.0%). Children’s self-esteem differed according to their mother’s responsive parenting trajectory. First-graders with mothers displaying the low responsive parenting trajectory were more likely to have lower self-esteem than children of mothers with the moderate responsive parenting trajectory and children of mothers with the high responsive parenting trajectory. The longitudinal link between mother-reported responsive parenting patterns during infancy and child-reported self-esteem at first grade was verified. This finding highlights the significance of early responsive parenting from mothers as a predictor of the self-esteem of children in later developmental stages.

Associations between Family Functioning and Maternal Behavior on Default Mode Network Connectivity in School-Age Children

Background: Most early children's experiences will occur in a family context; therefore, the quality of this environment is critical for development outcomes. Not many studies have assessed the correlations between brain functional connectivity (FC) in important areas such as the default mode network (DMN) and the quality of parent-child relationships in school-age children and early adolescence. The quality of family relationships and maternal behavior have been suggested to modulate DMN FC once they act as external regulators of children's affect and behavior. Objective: We aimed to test the associations between the quality of family environment/maternal behavior and FC within the DMN of school-age children. Method: Resting-state, functional magnetic resonance imaging data, were collected from 615 children (6-12 age range) enrolled in the Brazilian High-Risk Cohort (HRC) study. We assessed DMN intra-connectivity between the medial prefrontal cortex (mPFC), posterior cingulate cortex (PCC), and inferior parietal lobule (IPL-bilateral) regions. The family functioning was assessed by levels of family cohesiveness and conflict and by maternal behavior styles such as maternal responsiveness, maternal stimulus to the child's autonomy, and maternal overprotection. The family environment was assessed with the Family Environment Scale (FES), and maternal behavior was assessed by the mother's self-report. Results: We found that the quality of the family environment was correlated with intra-DMN FC. The more conflicting the family environment was, the greater the FC between the mPFC-left IPL (lIPL), while a more cohesive family functioning was negatively correlated with FC between the PCC-lIPL. On the other hand, when moderated by a positive maternal behavior, cohesive family functioning was associated with increased FC in both regions of the DMN (mPFC-lIPL and PCC-lIPL). Conclusions: Our results highlight that the quality of the family environment might be associated with differences in the intrinsic DMN FC.

The context and development of the early relational health screen

Early relational experiences are key drivers for developing social emotional capacities, educational achievement, mental health, physical health, and overall wellbeing. The child health sectors are committed to promotion, prevention, and early intervention that optimize children's health and development, often employing evidence-based screening as foundational practices. Despite a variety of validated parent-infant observational assessment tools, few are practical within busy practice settings, acceptable with all racial and ethnic groups and ready for universal adoption. In response to this need, a team of clinicians, early childhood educators, researchers and infant mental health specialists collaborated to develop and test a novel video-based, dyadic relational screening and monitoring tool, the Early Relational Health Screen (ERHS). This tool uniquely focuses on the early parent-child relationship (6-24 months), within the construct of early relational health (ERH). Initial testing demonstrated that the ERHS is a valid, reliable, feasible, and useful screening and monitoring tool for clinical applications. The ERHS was further developed within a population-based, prospective research study and adapted with brief video feedback for parents in the home visiting and child health sectors. The ERHS and its adaptations appear to advance ERH and equity within the transforming child health and public health care systems of today.

Parent-Child Play and the Emergence of Externalizing and Internalizing Behavior Problems in Childhood: A Systematic Review

It has widely been accepted that play has a major role in human development. The play situation is considered a save and controlled space in which children can learn to express their problems and to regulate their emotions, thus promoting emotional and behavioral adjustment. In early childhood, this process is thought to emerge in close interaction with caregivers. Parent-child play is thus viewed as an ideal window for parents to connect with their children and to support them in their social-emotional development. In this preregistered systematic review, we sought to integrate evidence from developmental and clinical psychology to shed more light on the role of parents in the relationship between parent-child play and children's behavioral adjustment as expressed in internalizing or externalizing behavior. Our review revealed that increased harsh control during play interactions as well as a lack of parental responsiveness, warmth and sensitivity were found to be associated with increased behavioral problems. Yet, no protective effect of warmth or responsiveness could be found in the context of risk groups. Moreover, the included studies indicated that positive affect expressed by parents during parent-child play was associated with fewer behavior problems in children, while negative affect was associated with more behavior problems. In general, this review revealed that quality and quantity of playful parent-child interactions were reduced in children with behavioral problems of both domains compared to children without behavioral problems. These findings illustrate the important role of parental characteristics during play interactions and their possible impact on children's behavioral adjustment.

Measuring early life adversity: A dimensional approach

Exposure to adversity in childhood is associated with elevations in numerous physical and mental health outcomes across the life course. The biological embedding of early experience during periods of developmental plasticity is one pathway that contributes to these associations. Dimensional models specify mechanistic pathways linking different dimensions of adversity to health and well-being outcomes later in life. While findings from existing studies testing these dimensions have provided promising preliminary support for these models, less agreement exists about how to measure the experiences that comprise each dimension. Here, we review existing approaches to measuring two dimensions of adversity: threat and deprivation. We recommend specific measures for measuring these constructs and, when possible, document when the same measure can be used by different reporters and across the lifespan to maximize the utility with which these recommendations can be applied. Through this approach, we hope to stimulate progress in understanding how particular dimensions of early environmental experience contribute to lifelong health.

Integrative Brain Dynamics in Childhood Bullying Victimization: Cognitive and Emotional Convergence Associated With Stress Psychopathology

Bullying victimization is a form of psychological stress that is associated with poor outcomes in the areas of mental health and learning. Although the emotional maladjustment and memory impairment following interpersonal stress are well documented, the mechanisms of complex cerebral dysfunctions have neither been outlined nor studied in depth in the context of childhood bullying victimization. As a contribution to the cross-disciplinary field of developmental psychology and neuroscience, we review the neuropathophysiology of early life stress, as well as general psychological stress to synthesize the data and clarify the versatile dynamics within neuronal networks linked to bullying victimization. The stress-induced neuropsychological cascade and associated cerebral networks with a focus on cognitive and emotional convergence are described. The main findings are that stress-evoked neuroendocrine reactivity relates to neuromodulation and limbic dysregulation that hinder emotion processing and executive functioning such as semantic cognition, cognitive flexibility, and learning. Developmental aspects and interacting neural mechanisms linked to distressed cognitive and emotional processing are pinpointed and potential theory-of-mind nuances in targets of bullying are presented. The results show that childhood stress psychopathology is associated with a complex interplay where the major role belongs to, but is not limited to, the amygdala, fusiform gyrus, insula, striatum, and prefrontal cortex. This interplay contributes to the sensitivity toward facial expressions, poor cognitive reasoning, and distress that affect behavioral modulation and emotion regulation. We integrate the data on major brain dynamics in stress neuroactivity that can be associated with childhood psychopathology to help inform future studies that are focused on the treatment and prevention of psychiatric disorders and learning problems in bullied children and adolescents.

Exceeding expectations after perinatal risks for poor development: associations in term- and preterm-born preschoolers

OBJECTIVE

To define parenting/social characteristics associated with better-than-expected cognitive and motor outcomes in preschoolers at similar perinatal biological risk-level including various gestational ages at birth (GA) and perinatal complications.

STUDY DESIGN

Prospective cohort study (n = 87) of children at four years, median GA 29 weeks (IQR 26, 38). Assessments included Differential Ability Scales, Movement Assessment Battery, parenting styles, and social risk scores. Perinatal risk factors were weighted based on regression models for each outcome; individual calculated risk scores became predictors to extract standardized residuals from the mean (>1 SD above mean = better-than-expected). Mixed-effect regressions examined associations between positive adaptation and parenting/social factors.

RESULT

Perinatal risk scores explained 21-53% outcome variability. Children across all GA displayed positive adaptation. Children of parents with higher authoritarian scores had higher odds of better-than-expected outcomes (OR 1.17, p = 0.0002).

CONCLUSION

Parental structure may promote positive adaptation at preschool age in children with perinatal risk factors for poor development, including extreme prematurity.

Mothers’ Attachment Representations and Children’s Brain Structure

Ample research demonstrates that parents’ experience-based mental representations of attachment—cognitive models of close relationships—relate to their children’s social-emotional development. However, no research to date has examined how parents’ attachment representations relate to another crucial domain of children’s development: brain development. The present study is the first to integrate the separate literatures on attachment and developmental social cognitive neuroscience to examine the link between mothers’ attachment representations and 3- to 8-year-old children’s brain structure. We hypothesized that mothers’ attachment representations would relate to individual differences in children’s brain structures involved in stress regulation—specifically, amygdala and hippocampal volumes—in part via mothers’ responses to children’s distress. We assessed 52 mothers’ attachment representations (secure base script knowledge on the Attachment Script Assessment and self-reported attachment avoidance and anxiety on the Experiences in Close Relationships scale) and children’s brain structure. Mothers’ secure base script knowledge was significantly related to children’s smaller left amygdala volume but was unrelated to hippocampal volume; we found no indirect links via maternal responses to children’s distress. Exploratory analyses showed associations between mothers’ attachment representations and white matter and thalamus volumes. Together, these preliminary results suggest that mothers’ attachment representations may be linked to the development of children’s neural circuitry related to stress regulation.

Racial Discrimination, Mental Health, and Parenting Among African American Mothers of Preschool-Aged Children

OBJECTIVE

Indirect exposure to racism experienced by a caregiver (ie, vicarious racism) is associated with poor outcomes for children, but mechanisms of vicarious racism transmission are poorly understood. The purpose of this study was to examine the relationship between experiences of racial discrimination and parenting among African American mothers and to identify psychological mediators and moderators of this relationship.

METHOD

African American mothers (N = 250) with young children (mean age = 3.7 years old) reported on perceived racial discrimination (Race-Related Events Scale), parenting (Parenting Stress Index, Parenting Styles and Dimensions Questionnaire), coping (Coping Strategies Index), and mental health (Stress Overload Scale, Beck Depression Inventory). Multivariable linear regression was used to examine associations between perceived racial discrimination and parenting and to test coping as a moderator of these relationships. Ordinary least-squares regression-based path analysis with bootstrapping was used to examine mediation by stress overload and depressive symptoms.

RESULTS

At least one experience of racial discrimination was reported by 57% of women. Experiences of racial discrimination were associated with increased parenting stress (β = 0.69, p = .02), and this relationship was mediated by stress overload (95% CI [0.35, 1.09]) and depressive symptoms (95% CI [0.27, 1.18]). Racial discrimination was not associated with parenting styles, and coping strategies largely did not moderate the relationships examined.

CONCLUSION

Racial discrimination has harmful intergenerational effects on African American children and families. Systemic-level interventions are needed, including adoption of policies to promote racial justice and eliminate structural racism in the United States. Future research on coping strategies specific to racism-related stress is needed to inform approaches to intervention.
