This study addresses a gap in the attachment literature by investigating maternal neural response to cry related to infant attachment classifications and behaviors. Twenty-two primiparous mothers and their 18-month old infants completed the Strange Situation (SS) procedure to elicit attachment behaviors. During a separate functional MRI session, mothers were exposed to their own infant's cry sound, as well as an unfamiliar infant's cry and control sound. Maternal neural response to own infant cry related to both overall attachment security and specific infant behaviors. Mothers of less secure infants maintained greater activation to their cry in left parahippocampal and amygdala regions and the right posterior insula consistent with a negative schematic response bias. Mothers of infants exhibiting more avoidant or contact maintaining behaviors during the SS showed diminished response across left prefrontal, parietal, and cerebellar areas involved in attentional processing and cognitive control. Mothers of infants exhibiting more disorganized behavior showed reduced response in bilateral temporal and subcallosal areas relevant to social cognition and emotion regulation. No differences by attachment classification were found. Implications for attachment transmission models are discussed. [ABSTRACT FROM AUTHOR]

Background: Increased adiposity during pregnancy may be related to offspring risk for mental health disorders, although the biological mechanisms are poorly understood. One promising hypothesis is that factors secreted from adipocytes such as leptin and adiponectin may explain this association. The current study examined whether pregnancy or umbilical cord blood concentrations of leptin and/or adiponectin a) predict elevated infant negative affect at 6 months (an early life marker of risk for psychopathology); and b) help explain the association between pregnancy adiposity and increased infant negative affect., Methods: Data came from a prospective cohort (N = 305) of pregnant individuals and their offspring. Second trimester adiposity was assessed using air displacement plethysmography. Concentrations of leptin and adiponectin were measured in second trimester plasma and umbilical cord plasma. Infant negative affect was assessed by standardized observation at 6 months. Second trimester inflammation was assessed using a comprehensive panel of cytokines., Results: Lower second trimester adiponectin was associated with elevated infant negative affect, and mediated the effect of pregnancy adiposity on infant negative affect. This association was independent of the effect of second trimester inflammation. Umbilical cord leptin also predicted higher infant negative affect and mediated the association between pregnancy adiposity and infant negative affect., Conclusions: This is the first study to link pregnancy adiponectin or cord blood leptin to infant markers of risk for psychopathology, and the first to demonstrate that these adipokines mediate the association between pregnancy adiposity and offspring behavioral outcomes, suggesting novel markers of risk and potential mechanisms of effect., Competing Interests: Declaration of competing interest We have no known conflicts of interest to disclose., (Copyright © 2024 Elsevier Inc.

Our primary objective was to document COVID-19 induced changes to perinatal care across the USA and examine the implication of these changes for maternal mental health. We performed an observational cross-sectional study with convenience sampling using direct patient reports from 1918 postpartum and 3868 pregnant individuals collected between April 2020 and December 2020 from 10 states across the USA. We leverage a subgroup of these participants who gave birth prior to March 2020 to estimate the pre-pandemic prevalence of specific birthing practices as a comparison. Our primary analyses describe the prevalence and timing of perinatal care changes, compare perinatal care changes depending on when and where individuals gave birth, and assess the linkage between perinatal care alterations and maternal anxiety and depressive symptoms. Seventy-eight percent of pregnant participants and 63% of postpartum participants reported at least one change to their perinatal care between March and August 2020. However, the prevalence and nature of specific perinatal care changes occurred unevenly over time and across geographic locations. The separation of infants and mothers immediately after birth and the cancelation of prenatal visits were associated with worsened depression and anxiety symptoms in mothers after controlling for sociodemographic factors, mental health history, number of pregnancy complications, and general stress about the COVID-19 pandemic. Our analyses reveal widespread changes to perinatal care across the US that fluctuated depending on where and when individuals gave birth. Disruptions to perinatal care may also exacerbate mental health concerns, so focused treatments that can mitigate the negative psychiatric sequelae of interrupted care are warranted., (© 2022.

The impact of COVID-19-related stress on perinatal women is of heightened public health concern given the established intergenerational impact of maternal stress-exposure on infants and fetuses. There is urgent need to characterize the coping styles associated with adverse psychosocial outcomes in perinatal women during the COVID-19 pandemic to help mitigate the potential for lasting sequelae on both mothers and infants. This study uses a data-driven approach to identify the patterns of behavioral coping strategies that associate with maternal psychosocial distress during the COVID-19 pandemic in a large multicenter sample of pregnant women (N = 2876) and postpartum women (N = 1536). Data was collected from 9 states across the United States from March to October 2020. Women reported behaviors they were engaging in to manage pandemic-related stress, symptoms of depression, anxiety and global psychological distress, as well as changes in energy levels, sleep quality and stress levels. Using latent profile analysis, we identified four behavioral phenotypes of coping strategies. Critically, phenotypes with high levels of passive coping strategies (increased screen time, social media, and intake of comfort foods) were associated with elevated symptoms of depression, anxiety, and global psychological distress, as well as worsening stress and energy levels, relative to other coping phenotypes. In contrast, phenotypes with high levels of active coping strategies (social support, and self-care) were associated with greater resiliency relative to other phenotypes. The identification of these widespread coping phenotypes reveals novel behavioral patterns associated with risk and resiliency to pandemic-related stress in perinatal women. These findings may contribute to early identification of women at risk for poor long-term outcomes and indicate malleable targets for interventions aimed at mitigating lasting sequelae on women and children during the COVID-19 pandemic., (© 2022.

Effortful control (EC) is a regulatory capacity that refers to children's ability to inhibit a dominant response to perform a subdominant response. Although attempts have been made to identify early predictors of children's EC, the confluence and interaction of child-, familial-, and community factors has not been pursued adequately. This study investigated how predictors from different aspects of children's rearing environment interacted to predict later EC. In a sample of 88 primiparous women with elevated depressive symptomotology and low household income, we examined how children's own psychobiology (baseline cortisol), familial relationship (mother-child attachment), and community resources (social support) at 17 months independently and jointly predicted EC at age 5. Our results showed that, controlling for maternal depressive symptomotology and household income, predictors from child-, familial-, and community-aspect function integratively, rather than independently, in predicting later EC. Specifically, within the context of a secure attachment relationship, baseline cortisol positively predicts later EC only for children of mothers who reported low social support. Whereas within the context of an insecure attachment relationship, baseline cortisol negatively predicts later EC, regardless of the perceived social support levels. Our results highlighted the importance of taking into consideration predictors from multiple aspects for intervention designs., (© 2020 Wiley Periodicals LLC.)

Adversity early in life is associated with systemic inflammation by adolescence and beyond. At present, few studies have investigated the associations between different forms of adversity and inflammation during infancy, making it difficult to specify the origins of disease vulnerability. This study examined the association between multiple forms of early adversity - socioeconomic status disadvantage, familial stress, maternal depression, and security of attachment - and individual differences in a composite measure of pro-inflammatory cytokines (IL-1β, IL-6, IL-8, and tumor necrosis factor-alpha) and the inflammatory protein C-reactive protein that were collected via saliva when (n = 49) children were 17 months old. In addition to gauging the direct effects of adversity, we also tested the hypothesis that infants' attachment relationship with their mother might buffer infants against the immunologic effects of early adversity. Results show that familial stress, maternal depression, and security of attachment were directly associated with infant salivary inflammation and that attachment status moderated the effect of maternal depression. The findings suggest that exposure to certain forms of adversity very early in life may engender a pro-inflammatory phenotype with possible life-long implications for health.

Early life adversity is associated with adult elevations of inflammatory markers such as circulating levels of C-reactive protein (CRP). Few studies have examined inflammation levels during infancy nor the associations between sources of adversity and concurrent inflammation early in life. Existing evidence suggests that early adversity in the form of compromised caregiving relationships can embed itself into young children's biology with implications for lifelong development. This study examined the association between infants' histories of attachment with their mothers and salivary concentrations of CRP, all of which were assessed when infants were 17 months of age. Results show that infants with disorganized attachments histories and those exhibiting disorganized and avoidant regulatory behaviors when faced with an attachment stressor were all associated with significantly elevated levels of salivary CRP. These results suggest that exposure to significant interpersonal adversity very early in life may engender a proinflamotry phenotype with life-long implications for health., (Copyright © 2016 Elsevier B.V.

The present study used functional magnetic resonance imaging to investigate how a mother's experience of neglect in her own childhood is associated with her neural response to her infant's distress cues. During scanning, 22 high-risk primiparous mothers were exposed to both their own 18-month-old infant's cry sound and a control sound. Mothers' continuous Neglect subscale scores from the Childhood Trauma Questionnaire were examined as a predictor of their neural response to own infant cry > control sound. Mothers who reported high levels of neglect from childhood showed regions of hyperactivation to their infant's cry (relative to control sound) in the anterior and posterior cingulate cortices and insula as well as specific prefrontal (precentral gyrus) and parietal (posterior supramarginal gyrus) areas. These results may suggest how important early life experiences are for future parenting responses and behaviors.

The purpose of the current study was to predict concurrent levels of problem behaviors from young children's baseline cortisol and attachment classification, a proxy for the quality of caregiving experienced. In a sample of 58 children living at or below the federal poverty threshold, children's baseline cortisol levels, attachment classification, and problem behaviors were assessed at 17 months of age. We hypothesized that an interaction between baseline cortisol and attachment classification would predict problem behaviors above and beyond any main effects of baseline cortisol and attachment. However, based on limited prior research, we did not predict whether or not this interaction would be more consistent with diathesis-stress or differential susceptibility models. Consistent with diathesis-stress theory, the results indicated no significant differences in problem behavior levels among children with high baseline cortisol. In contrast, children with low baseline cortisol had the highest level of problem behaviors in the context of a disorganized attachment relationship. However, in the context of a secure attachment relationship, children with low baseline cortisol looked no different, with respect to problem behavior levels, then children with high cortisol levels. These findings have substantive implications for the socioemotional development of children reared in poverty., (Copyright © 2017 Elsevier Inc. All rights reserved.)

The foundations of emotion regulation are organized, in part, through repeated interactions with one's caregiver in infancy. Less is known about how stress physiology covaries between a mother and her infant within these interactions, leaving a gap in our understanding of how the biological basis of emotion regulation develops. This study investigated physiological attunement between mothers and their 5-month-old infants, as well as the influence of maternal depression and anxiety, during stress recovery. During the reengagement phase of the Still Face Paradigm, mother-infant dyads exhibited negative attunement, as measured by inverse covariation of respiratory sinus arrhythmia (RSA). Increases in maternal RSA corresponded to decreases in infant RSA, underscoring dyadic adjustment during recovery. Moreover, infant regulation differed as a function of maternal anxiety, with more anxious mothers having infants with higher RSA during reengagement. Implications for the consolidation of regulatory capabilities within the context of the early caregiving relationship are discussed., (© 2016 Wiley Periodicals, Inc.)

Infant-caregiver attachment disorganization has been linked to many long-term negative psychosocial outcomes. While various prevention programs appear to be effective in preventing disorganized attachment, methods currently used to identify those at risk are unfortunately either overly general or impractical. The current investigation tested whether women's prenatal biases in identifying infant expressions of emotion--tendencies previously shown to relate to some of the maternal variables associated with infant attachment, including maternal traumatization, trauma symptoms, and maternal sensitivity--could predict infant attachment classification at 18 months postpartum. Logistic regression analyses revealed that together with women's adult history of high betrayal traumatization, response concordance with a normative reference sample in labeling infant expressions as negatively valenced, and the number of infant facial expressions that participants classified as "sad" and "angry" predicted subsequent infant attachment security versus disorganization. Implications for screening and prevention are discussed., (© 2014 Michigan Association for Infant Mental Health.)

There is now substantial evidence that parental attributions for power over negative caregiving outcomes play an important role in the intergenerational transmission of child maltreatment. Despite the substantial research and clinical significance of this construct, and the widely held assumption that it represents a trait-like attributional style, there is a lack of empirical support for its long-term stability, especially over the transition to parenthood. The present study examined the stability of 88 at-risk women's perceived power over caregiving failure from the 3rd trimester of their 1st pregnancy to 18 months postnatal. Although results showed no significant change in overall self-reported perceived power over caregiving failure across time, subcomponents that separately assess perceived importance of adult and child factors both decreased over time, driven by increasing external attributions. Examination of subscale scores further revealed consistency in women's attributional style for their own and their child's behavior, and for positive and negative events, over time. Individual differences in these patterns suggested that past and present difficulties interfered with normative shifts such that maternal stress and history of trauma were associated with an increased sense that children control problematic events while decreasing mothers' own sense of control. Research and clinical implications are discussed.

Associations among 53 primiparous women's Adult Attachment Interview classifications (secure-autonomous vs. insecure-dismissing) and physiological and self-reported responses to infant crying were explored. Heart rate, skin conductance levels, and respiratory sinus arrhythmia (RSA) were recorded continuously. In response to the cry, secure-autonomous women demonstrated RSA declines, consistent with approach-oriented responses. Insecure-dismissing women displayed RSA and electrodermal increases, consistent with behavioral inhibition. Furthermore, insecure-dismissing women rated the cries as more aversive than secure-autonomous women. Nine months postpartum, secure-autonomous women, who prenatally manifested an approach-oriented response to the unfamiliar cry stimulus, were observed as more sensitive when responding to their own distressed infant, whereas women classified prenatally as insecure-dismissing were observed as less sensitive with their own infants., (© 2013 The Authors.

This study examined mothers' physiological reactivity in response to infant distress during the Still-Face Paradigm. We aimed to explore normative regulatory profiles and associated physiological and behavioral processes in order to further our understanding of what constitutes regulation in this dyadic context. We examined physiological patterns--vagal tone, indexed by respiratory sinus arrhythmia (RSA)--while mothers maintained a neutral expression over the course of the still face episode, as well as differential reactivity patterns in mothers with depression symptoms compared to non-depressed mothers. Behavioral and physiological data were collected from mothers of 5-month-old infants during the emotion suppression phase of the Still-Face Paradigm. We used Hierarchical Linear Modeling to examine changes in mothers' RSA during infant distress and explored maternal depression as a predictor of physiological profiles. Mothers were generally able to maintain a neutral expression and simultaneously demonstrated a mean-level increase in RSA during the still face episode compared to baseline, indicating an active regulatory response overall. A more detailed time-course examination of RSA trajectories revealed that an initial RSA increase was typically followed by a decrease in response to peak infant distress, suggesting a physiological mobilization response. However, this was not true of mothers with elevated depressive symptoms, who showed no change in RSA during infant distress. These distinct patterns of infant distress-related physiological activation may help to explain differences in maternal sensitivity and adaptive parenting., (Copyright © 2013 Elsevier Inc.

Do infants reared in poverty exhibit certain physiological traits that make them susceptible to the positive and negative features of their caregiving environment? Guided by theories of differential susceptibility and biological sensitivity to context, we evaluated whether high baseline respiratory sinus arrhythmia (RSA) operates as a susceptibility factor among infants reared in poverty (N = 73). Baseline RSA at 5 months, the quality of the attachment relationship at 17 months, and the interaction of these two factors were included in our models as predictors of problem behavior at 17 months. Consistent with theory, results showed no significant differences in problem behavior among infants with low baseline RSA; however, infants with high baseline RSA exhibited the lowest levels of problem behavior if reared in an environment that fostered security, and they exhibited the highest levels of problem behavior if reared in an environment that fostered disorganization. These results have important implications for the psychological health of infants living in poverty.

Depressed mothers show negatively biased responses to their infants' emotional bids, perhaps due to faulty processing of infant cues. This study is the first to examine depression-related differences in mothers' neural response to their own infant's emotion faces, considering both effects of perinatal depression history and current depressive symptoms. Primiparous mothers (n = 22), half of whom had a history of major depressive episodes (with one episode occurring during pregnancy and/or postpartum), were exposed to images of their own and unfamiliar infants' joy and distress faces during functional neuroimaging. Group differences (depression vs. no-depression) and continuous effects of current depressive symptoms were tested in relation to neural response to own infant emotion faces. Compared to mothers with no psychiatric diagnoses, those with depression showed blunted responses to their own infant's distress faces in the dorsal anterior cingulate cortex. Mothers with higher levels of current symptomatology showed reduced responses to their own infant's joy faces in the orbitofrontal cortex and insula. Current symptomatology also predicted lower responses to own infant joy-distress in left-sided prefrontal and insula/striatal regions. These deficits in self-regulatory and motivational response circuits may help explain parenting difficulties in depressed mothers.

Adult caregivers' idealization of their parents as assessed by the Adult Attachment Interview is a risk factor for the intergenerational transmission of the insecure-avoidant attachment style. This study evaluated a briefer screening approach for identifying parental idealization, testing the utility of prenatal maternal self-report measures of recalled betrayal trauma and parental care in childhood to predict observationally assessed infant attachment avoidance with 58 mother-infant dyads 18 months postpartum. In a logistic regression that controlled for maternal demographics, prenatal psychopathology, and postnatal sensitivity, the interaction between women's self-reported childhood high betrayal trauma and the level of care provided to them by their parents was the only significant predictor of 18-month infant security versus avoidance. Results suggest that betrayal trauma and recalled parental care in childhood can provide a means of identifying caregivers whose infant children are at risk for avoidant attachment, potentially providing an efficient means for scientific studies and clinical intervention aimed at preventing the intergenerational transmission of attachment problems.

Research on maternal neural response to infant distress highlights circuits that may underlie differences in quality of maternal behavior. However, it is far from clear which circuits are relevant to maternal sensitivity, as opposed to other maternal behavioral dimensions, particularly after the early postpartum. This study examined maternal sensitivity, intrusiveness, and mother-infant dyadic harmony as correlates of mothers' neural responses to the cries of their own infants. Twenty-two primiparous mothers were observed during an interaction with their infants at 18 months postpartum. In a separate functional neuroimaging session, mothers were exposed to their own infant's cry sound, as well as unfamiliar infant's cry and control sounds. Mothers who displayed more sensitive behaviors with their infant exhibited greater activation to their own infant's cry compared to that of an unfamiliar infant in the right frontal pole and inferior frontal gyrus. Mothers who displayed more intrusive behaviors with their infant showed greater activation in the left anterior insula and temporal pole, while mothers who had more harmonious interactions with their infant displayed greater activation in left hippocampal regions. The roles of these areas in the regulation of maternal emotion and stress, self and other awareness, and empathy are examined., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Previous research has established that maternal depression is a risk factor for a variety of negative developmental outcomes among infants and children. Although low levels of maternal sensitivity have been hypothesized to explain this risk, the biological mechanisms underlying the association between maternal depressive symptoms and low levels of maternal sensitivity have been largely underexplored. This study examined the roles of postnatal depressive symptoms and parasympathetic nervous system functioning as predictors of low levels of maternal sensitivity, during a stressful mother-infant interaction-the reunion phase of the Still-Face Paradigm. Depressive symptoms and traitlike predispositions toward parasympathetic dysregulation, as indexed by low resting levels of respiratory sinus arrhythmia, were associated independently with less sensitive parenting. Discussion considers that during stressful mother-infant interactions, both mothers with depressive symptoms and mothers predisposed to parasympathetic dysregulation may have fewer emotional, physiological, and psychological resources with which to respond sensitively to their infants' cues., (Copyright © 2012 Michigan Association for Infant Mental Health.)

The current study explored the effects of talking on respiratory sinus arrhythmia (RSA) during a semi-structured emotional interview (Adult Attachment Interview) using 76 female undergraduates. The effectiveness of 2 different methodological approaches (i.e. talking baseline or transfer function) was explored as respiratory control during talking tasks. RSA was collected during resting baseline, talking baseline, and interview conditions. Subjective reports of distress were higher in the interview than in the other 2 conditions. Mean RSA levels were significantly lower in the 2 talking tasks than in the resting baseline. After applying a transfer function for respiratory control, there were no significant differences between the 3 conditions. Moderator analyses yielded lower RSA values in the talking baseline and interview conditions for participants who reported greater distress during the interview. It was concluded that respiratory controls are likely necessary when using RSA in talking paradigms and that both approaches appeared to be adequate., (Copyright © 2011 Elsevier B.V.

This study investigated depression-related differences in primiparous mothers' neural response to their own infant's distress cues. Mothers diagnosed with major depressive disorder (n = 11) and comparison mothers with no diagnosable psychopathology (n = 11) were exposed to their own 18-months-old infant's cry sound, as well as unfamiliar infant's cry and control sound, during functional neuroimaging. Depressed mothers' response to own infant cry greater than other sounds was compared to non-depressed mothers' response in the whole brain [false discovery rate (FDR) corrected]. A continuous measure of self-reported depressive symptoms (CESD) was also tested as a predictor of maternal response. Non-depressed mothers activated to their own infant's cry greater than control sound in a distributed network of para/limbic and prefrontal regions, whereas depressed mothers as a group failed to show activation. Non-depressed compared to depressed mothers showed significantly greater striatal (caudate, nucleus accumbens) and medial thalamic activation. Additionally, mothers with lower depressive symptoms activated more strongly in left orbitofrontal, dorsal anterior cingulate and medial superior frontal regions. Non-depressed compared to depressed mothers activated uniquely to own infant greater than other infant cry in occipital fusiform areas. Disturbance of these neural networks involved in emotional response and regulation may help to explain parenting deficits in depressed mothers.

This study investigated continuity and stability of hypothalamic-pituitary-adrenal (HPA) and sympathetic nervous system (SNS) response measures in mother-infant dyads across 2 different types of social stress sessions. Synchrony of response trajectories across systems (SNS-HPA coordination) and partners (mother-infant attunement) was addressed, as were associations with infant temperament. Primiparous mothers and their 18-month-old infants (n = 86 dyads) completed an attachment stressor--Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978)--at Session 1 and challenge stressors--cleanup task and emotion task battery--at Session 2. Mother and infant saliva samples collected to index pre-stress, stress, and post-stress response during each session were assayed for cortisol (HPA marker) and salivary alpha-amylase (sAA; SNS marker). Multilevel modeling of cortisol/sAA trajectories across sessions revealed rank-order stability in mother/infant stress measures but discontinuity in absolute levels; cortisol trajectories were higher during attachment stress, and sAA trajectories were higher during challenge stress. Varying degrees of mother-infant attunement were found across sessions/systems. Infant surgency predicted higher stress measures, and negative affect and effortful control predicted lower stress measures, though associations depended on session/system. Findings are discussed in terms of advancing a multisystemic, contextual definition of developing stress responsiveness.

Background: Neural correlates of stress regulation via the hypothalamic-pituitary-adrenal (HPA) axis have been identified, but little is known about how these apply to real-world interpersonal stress contexts such as mother-infant interaction. We extended stress regulation research by examining maternal neural activation to infant cry related to HPA regulation with their infants., Methods: Twenty-two primiparous mothers listened to the cry sounds of their own 18-month-old infant and an unfamiliar infant and a control sound during functional magnetic resonance imaging scanning. Salivary cortisol was collected at four timepoints in a separate session involving the Strange Situation stressor. Cortisol trajectories were modeled with hierarchical linear modeling, and trajectory terms were used to predict neural response to own infant cry., Results: Mothers who showed less HPA reactivity-indexed by trajectory curvature rather than level-showed increased activation to the cry of their infant relative to control sound across limbic/paralimbic and prefrontal circuits. These included periaqueductal gray, right insula, and bilateral orbitofrontal cortex as well as anterior cingulate-medial prefrontal cortex. Activations overlapped to some extent with previous HPA regulation findings and converged more extensively with circuits identified in other maternal response paradigms., Conclusions: Maternal stress regulation involves both circuits found across stressor types (i.e., prefrontal) and areas unique to the mother-infant relationship (i.e., limbic/paralimbic). The shape of the HPA response trajectory of mothers was more important than the level of such response in defining stress-related neural correlates. Future research should consider dimensions of the stress context and of physiological trajectories to define stress-regulatory circuits., (Published by Elsevier Inc.)

Despite growing interest in conceptualizing ADHD as involving disrupted emotion regulation, few studies have examined the physiological mechanisms related to emotion regulation in children with this disorder. This study examined parasympathetic and sympathetic nervous system reactivity via measures of respiratory sinus arrhythmia (RSA) and cardiac pre-ejection period (PEP) in children with ADHD (n=32) and typically developing controls (n=34), using a novel emotion task with four conditions: negative induction, negative suppression, positive induction, and positive suppression of affect. Both groups showed strong task-response effects in RSA. However, typically developing children showed systematic variation in parasympathetic activity (RSA) depending on both emotion valence (more activation for negative emotion, reduced activation for positive emotion) and task demand (more activation for suppression than induction). In contrast, children with ADHD displayed a stable pattern of elevated parasympathetic activity (RSA) across all task conditions compared to baseline. No group differences in sympathetic activity (PEP) were observed. It is concluded ADHD in childhood is associated with abnormal parasympathetic mechanisms involved in emotion regulation.

We investigated the effects of timing and the course of maternal perinatal depressive symptoms on mother-infant hypothalamic-pituitary-adrenal (HPA) response profiles during an attachment stressor, as well as on within-dyad synchrony of stress profiles: coordination of HPA and sympathetic nervous system and infant-mother HPA attunement. Mothers (n = 86) completed the Center for Epidemiological Studies Depression Scale during pregnancy (Time 1 [T1]) and at 5 months (T2) and 18 months (T3) postnatal. At T3 mother-infant dyads completed the Strange Situation, and four saliva samples collected from both mothers and infants were assayed for cortisol and α-amylase. Hierarchical linear modeling was used to predict mother-infant cortisol response trajectories and within-dyad synchronies by main and interactive effects of T1-T3 Center for Epidemiological Studies Depression Scale scores. Main effects of earlier (T1, T2) depressive symptoms predicted mothers' cortisol trajectories and coordination, and interactions of T1 with postnatal (T2 and T3) symptoms predicted infants' cortisol trajectories, coordination, and attunement. Decomposition of interactions revealed more marked effects on infant cortisol trajectories when the mother shifted from higher to lower depressive symptoms (or vice versa) across the perinatal period. Shifts from lower to higher symptoms also predicted inverse coordination of cortisol with salivary α-amylase and greater attunement of infant with mother cortisol. Implications for the development and transmission of stress dysregulation are discussed.

This study examined associations between interparental relationship dynamics and vagus system functioning in infancy. The functioning of the vagus system, part of the parasympathetic nervous system, indexes emotional reactivity and regulation. Interparental avoidance and dyadic adjustment constitute the focus of this study in order to bring attention to relationship dynamics not subsumed under overt conflict. Infants' baseline vagal tone and change in vagal tone in response to a novel toy were assessed at 5 months in a sample of high-risk mother-infant dyads (n=77). Maternal report of interparental avoidance demonstrated an association with infants' baseline vagal tone, while interparental dyadic adjustment was associated with change in infants' vagal tone from baseline to the novel toy. Infant gender moderated these associations. Maternal sensitivity did not mediate interparental relationship dynamics and infants' vagal functioning. Results are discussed in the context of emotional security theory., (Copyright © 2010 Elsevier Inc. All rights reserved.)

Young children's (n = 96) perceptions and appraisals of their parents' marital conflict were evaluated at age 5 and again at age 6. Concurrent reports of marital conflict by each parent and teachers' reports of children's classroom adjustment served as criteria against which to evaluate the validity of young children's perceptions. Children's perceptions of their parents' marital relationship were significantly correlated with spouses' reports at ages 5 and 6, as well as correlated with teacher reports of internalizing and externalizing problems. Consistent with the cognitive-contextual theory, children's tendency to blame themselves for their parents' conflict partially mediated the link between marital conflict and children's internalizing symptoms. In contrast, children's reports that they become involved in their parents' conflict partially mediated the effect of marital conflict on externalizing problems., ((PsycINFO Database Record (c) 2009 APA, all rights reserved).)

Research on early childhood personality has been scarce. Self-reports of Big Five personality traits were measured longitudinally with the Berkeley Puppet Interview when children were 5, 6, and 7 years of age. For comparative purposes, Big Five self-reports were collected in a sample of college students. The children's self-reports showed levels of consistency and differentiation that approached those of the college age sample. Children's personality self-reports demonstrated significant correlations across the 1- and 2-year longitudinal intervals. Substantial and increasing convergence was found between children's self-reports of Extraversion, Agreeableness, and Conscientiousness and conceptually relevant behavior ratings provided by mothers, fathers, and teachers. Children's self-reports of Neuroticism were unrelated to adults' reports but did predict sadness and anxious behavior observed in the laboratory. The results provide the beginnings of an account of how the Big Five dimensions begin to be salient and emerge as coherent, stable, and valid self-perceptions in childhood.

Background: Early childhood antisocial behaviour is a strong prognostic indicator for poor adult mental health. Thus, information about its etiology is needed. Genetic etiology is unknown because most research with young children focuses on environmental risk factors, and the few existing studies of young twins used only mothers' reports of behaviour, which may be biased., Method: We investigated genetic influences on antisocial behaviour in a representative-plus-high-risk sample of 1116 pairs of 5-year-old twins using data from four independent sources: mothers, teachers, examiner-observers previously unacquainted with the children, and the children themselves., Results: Children's antisocial behaviour was reliably measured by all four informants; no bias was detected in mothers', teachers', examiners', or children's reports. Variation in antisocial behaviour that was agreed upon by all informants, and thus was pervasive across settings, was influenced by genetic factors (82%) and experiences specific to each child (18%). Variation in antisocial behaviour that was specific to each informant was meaningful variation, as it was also influenced by genetic factors (from 33% for the children's report to 71% for the teachers' report)., Conclusions: This study and four others of very young twins show that genetic risks contribute strongly to population variation in antisocial behaviour that emerges in early childhood. In contrast, genetic risk is known to be relatively modest for adolescent antisocial behaviour, suggesting that the early-childhood form has a distinct etiology, particularly if it is pervasive across situations.

Objective: When there exists no single source of information (informant) to validly measure a characteristic, it is typically recommended that data from multiple informants be used. In psychiatric assessment and research, however, multiple informants often provide discordant data, which further confuse the measurement. Strategies such as arbitrarily choosing one informant or using the data from all informants separately generate further problems. This report proposes a theory to explain observed patterns of interinformant discordance and suggests a new approach to using data from multiple informants to measure characteristics of interest., Method: Using the example of assessment of developmental psychopathology in children, the authors propose a model in which the choice of informants is based on conceptualizing the contexts and perspectives that influence expression of the characteristic of interest and then identifying informants who represent those contexts and perspectives in such a way as to have the weaknesses of one informant canceled by the strengths of another., Results: Applications of this approach to several datasets indicate that when these principles are followed, a more reliable and valid consensus measure is obtained, and failure to obtain a reliable, valid measure is indicative of some deviation from the principles., Conclusions: In obtaining a consensus measure, the issue is not determining how many informants are needed but choosing the right set of informants.

Objective: To present the conceptual and methodological backgrounds for development of the MacArthur Assessment Battery for Middle Childhood and one of its constituent instruments, the MacArthur Health and Behavior Questionnaire (HBQ)., Method: As a component of HBQ development, research addressing "developmental psychopathology" as a nosological category of human disorder was reviewed. Such research bears, as its conceptual legacy, the strengths and frailties of the nosology from which the category was derived., Results: Defining developmental psychopathology has done much to foster psychiatric and medical awareness of the particular dilemmas and problems intrinsic to childhood psychopathology. On the other hand, its delineation has obscured the tendency for psychiatric morbidities to emerge gradually along trajectories of development, to involve interactions among organismic and contextual factors, and to represent "confluences" of childhood difficulties suggesting common, less distinctive origins among psychiatric and biomedical disorders. The recognizable psychopathology of adolescence is most often preceded by protean manifestations of early difficulties resulting from the conjoint operation of child-specific vulnerabilities and context-derived risk factors. Co-occurrences of mental, physical, social, and academic difficulties in children's lives are more frequently the rule than the exception, and isolated, singular psychopathology is less common in childhood than the prevailing diagnostic nosology may imply., Conclusions: The MacArthur Assessment Battery represents an effort to assemble, in a single set of instruments, measures of child, context, and health risk factors for the prevalent morbidities of middle childhood. The HBQ, a component of the Battery, is a parent- and teacher-report instrument that assesses mental health, physical health, social, and school adaptation in 4- to 8-year-old children.

Objective: Three sites collaborated to evaluate the differential performance of the MacArthur Health and Behavior Questionnaire (HBQ) and the Diagnostic Interview Schedule for Children Version IV (DISC-IV) in identifying DSM-IV psychopathology in young children., Method: A sample of 120 four- to eight-year-old nonreferred (community) (n = 67) and referred (clinical) (n = 53) children was examined. Mothers reported on their child's mental health symptoms using the HBQ (a dimensional measure with a clinical cutoff score) and the DISC-IV. Teachers independently reported on the child's symptoms and impairment in school using the teacher HBQ. Children self-reported on their symptoms using the companion Berkeley Puppet Interview., Results: On the basis of its derived clinical cutoff scores, the HBQ identified significantly more children with clinical symptoms of DSM-IVinternalizing psychopathology than the DISC-IV in both referred and nonreferred groups. There was a high level of agreement between the two measures in the identification of externalizing psychopathology. Children identified as having internalizing psychopathology by the HBQ were also rated as highly symptomatic and impaired by teachers., Conclusion: The findings support the general validity of the parent HBQ for the assessment of young child psychopathology and the hypothesis that it captures more internalizing psychopathology than the DISC-IV in this population.

Objective: Three sites collaborated to evaluate the reliability and validity of 2 measures, developed in tandem to assess symptomatology and impairment in 4- to 8-year-old children: the Berkeley Puppet Interview Symptomatology Scales (BPI-S) and the Health and Behavior Questionnaire (HBQ)., Method: In this case-control study, mothers, teachers, and children reported on multiple dimensions of children's mental health for 120 children (67 community and 53 clinic-referred children)., Results: The BPI-S and the parent and teacher versions of the HBQ demonstrated strong test-retest reliability and discriminant validity on a majority of symptom scales. Medium to strong effect sizes (Cohen d) indicated that children in the clinic-referred group were viewed by all 3 informants as experiencing significantly higher levels of symptomatology than nonreferred, community children., Conclusion: The availability of a set of multi-informant instruments that are psychometrically sound, developed in tandem, and developmentally appropriate for young children will enhance researchers' ability to investigate and understand symptomatology or the emergence of symptomatology in middle childhood.

In a prospective, longitudinal study we examined the psychometric properties of the self-perception scales of the Berkeley Puppet Interview (BPI). A total sample of 97 young children were assessed with the BPI at 3 time points: preschool, kindergarten, and first grade. The BPI assesses young children's self-perceptions of their school adjustment in 6 domains: academic competence, achievement motivation, social competence, peer acceptance, depression-anxiety, and aggression-hostility. Results showed that 4 1/2- to 7 1/2-year-olds possess a multidimensional self-concept that can be reliably measured and that the BPI is sensitive to normative changes and individual differences in young boys' and girls' views of themselves. Support for the method's validity was derived from consistent and meaningful patterns of convergence between children's self-perceptions and ratings by adult informants--mothers, fathers, and teachers--as well as standardized test scores. In fact, in this study, the concordance between young children's self-reports and parallel ratings by teachers or mothers were consistently as strong as if not stronger than the concordance between mothers' and teachers' ratings.
