Research investigating intergenerational effects of maternal trauma on infant stress reactivity and regulation is limited. Maternal mental health during pregnancy may be a contributor: psychopathology is a sequela of trauma exposure and predictor of altered self-regulatory capacity in offspring of affected mothers. We assessed associations among maternal lifetime trauma and infant stress responsivity, mediated by psychological symptoms in pregnancy. Mothers reported lifetime trauma history and anxiety, depressive, and posttraumatic stress symptoms during pregnancy. At infant age 6 months, stress reactivity and regulation were assessed via maternal behavior ratings (Infant Behavior Questionnaire-Revised, IBQ-R) and behavioral (negative mood) and physiological (respiratory sinus arrhythmia, RSA) markers during a laboratory stressor (Still-Face Paradigm). Maternal trauma was directly associated with lower infant physiological regulation and indirectly associated with lower levels of both infant behavioral and physiological regulation via higher maternal anxiety during pregnancy. Maternal trauma was also indirectly associated with higher infant reactivity via higher maternal anxiety during pregnancy. Post hoc analyses indicated differential contributions of maternal prenatal versus postnatal anxiety to infant outcomes. Findings highlight potential contributory mechanisms toward maladaptive child stress response, which has been associated with poor behavioral, cognitive, and academic outcomes.

Infants' neural responses to emotional faces are related to maternal anxiety / L. C. BOWMAN in Journal of Child Psychology and Psychiatry, 63-2 (February 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-2 (February 2022) . - p.152-164 Titre : Infants' neural responses to emotional faces are related to maternal anxiety Type de document : Texte imprimé et/ou numérique Auteurs : L. C. BOWMAN, Auteur ; S. A. MCCORMICK, Auteur ; Finola KANE-GRADE, Auteur ; W. XIE, Auteur ; Michelle BOSQUET ENLOW, Auteur ; C. A. NELSON, Auteur Article en page(s) : p.152-164 Langues : Anglais (eng) Mots-clés : Eeg/erp  Maternal anxiety  N290  Nc  P400  emotions  faces  infants Index. décimale : PER Périodiques Résumé : BACKGROUND: Postnatal maternal anxiety is common (estimates as high as 40% prevalence) and is associated with altered mother-infant interactions (e.g., reduced maternal emotional expression and engagement). Neural circuitry supporting infants' face and emotion processing develops in their first year. Thus, early exposure to maternal anxiety may impact infants' developing understanding of emotional displays. We examine whether maternal anxiety is associated with individual differences in typically developing infants' neural responses to emotional faces. METHODS: One hundred and forty two mother-infant dyads were assessed when infants were 5, 7, or 12?months old. Infants' electroencephalographic (EEG) data were recorded while passively viewing female happy, fearful, and angry faces. Three event-related potential (ERP) components, each linked to face and emotion processing, were evaluated: NC, N290, and P400. Infant ERP amplitude was related to concurrent maternal-report anxiety assessed with the Spielberger State-Trait Anxiety Inventory (Trait form). RESULTS: Greater maternal anxiety predicted more negative NC amplitude for happy and fearful faces in left and mid-central scalp regions, beyond covarying influences of maternal depression symptoms, infant negative emotionality, and infant age. CONCLUSIONS: Postnatal maternal anxiety is related to infants' neural processing of emotional expressions. Infants of mothers endorsing high trait anxiety may need additional attentional resources to process happy and fearful faces (expressions less likely experienced in mother-infant interactions). Future research should investigate mechanisms underlying this association, given possibilities include experiential, genetic, and prenatal factors.

Mother–infant attachment and the intergenerational transmission of posttraumatic stress disorder / Michelle BOSQUET ENLOW in Development and Psychopathology, 26-1 (February 2014)  

Public ISBD [article]  inDevelopment and Psychopathology > 26-1 (February 2014) . - p.41-65 Titre : Mother–infant attachment and the intergenerational transmission of posttraumatic stress disorder Type de document : Texte imprimé et/ou numérique Auteurs : Michelle BOSQUET ENLOW, Auteur ; Byron EGELAND, Auteur ; Annahir N. CARIELLO, Auteur ; Emily BLOOD, Auteur ; Rosalind J. WRIGHT, Auteur Article en page(s) : p.41-65 Langues : Français (fre) Index. décimale : PER Périodiques Résumé : Evidence for the intergenerational transmission of posttraumatic stress disorder (PTSD) is documented in the literature, although the underlying mechanisms are poorly understood. Attachment theory provides a framework for elucidating the ways in which maternal PTSD may increase offspring PTSD vulnerability. The current study utilized two independent prospective data sets to test the hypotheses that (a) maternal PTSD increases the probability of developing an insecure mother–infant attachment relationship and (b) an insecure mother–infant attachment relationship increases the risk of developing PTSD following trauma exposure in later life. In the first study of urban, primarily low-income ethnic/racial minority mothers and infants (N = 45 dyads), elevated maternal PTSD symptoms at 6 months were associated with increased risk for an insecure, particularly disorganized, mother–infant attachment relationship at 13 months. In the second birth cohort of urban, low-income mothers and children (N = 96 dyads), insecure (avoidant or resistant) attachment in infancy was associated in a dose–response manner with increased lifetime risk for a diagnosis of PTSD by adolescence. A history of disorganized attachment in infancy predicted severity of PTSD symptoms, including reexperiencing, avoidance, hyperarousal, and total symptoms, at 17.5 years. In both studies, associations between attachment and PTSD were not attributable to numerous co-occurring risk factors. The findings suggest that promoting positive mother–child relationships in early development, particularly in populations at high risk for trauma exposure, may reduce the incidence of PTSD.

Pathways to social-emotional functioning in the preschool period: The role of child temperament and maternal anxiety in boys and girls / Hannah F. BEHRENDT in Development and Psychopathology, 32-3 (August 2020)

Research is needed that specifies multiple early risk factors and outcomes simultaneously to demonstrate specificity. Using multigroup longitudinal path analysis in a sample of typically developing children (N = 541), we examined child temperament dimensions (surgency, negative affectivity, and regulation/effortful control) and maternal anxiety in infancy and age 2 as predictors of child externalizing, internalizing, dysregulation, and competence behaviors at age 3. Four primary patterns emerged. First, there was stability in temperament dimensions and maternal anxiety from infancy to age 3. Second, negative affectivity was implicated in internalizing problems and surgency in externalizing problems. Third, effortful control at age 2 was a potent mediator of maternal anxiety in infancy on age 3 outcomes. Fourth, there was suggestive evidence for transactional effects between maternal anxiety and child effortful control. Most pathways operated similarly for boys and girls, with some differences, particularly for surgency. These findings expand our understanding of the roles of specific temperamental domains and postnatal maternal anxiety in a range of social-emotional outcomes in the preschool period, and have implications for efforts to enhance the development of young children's social-emotional functioning and reduce risk for later psychopathology.

Temperament and sex as moderating factors of the effects of exposure to maternal depression on telomere length in early childhood / Michelle BOSQUET ENLOW in Development and Psychopathology, 37-2 (May 2025)  

Public ISBD [article]  inDevelopment and Psychopathology > 37-2 (May 2025) . - p.705-718 Titre : Temperament and sex as moderating factors of the effects of exposure to maternal depression on telomere length in early childhood Type de document : Texte imprimé et/ou numérique Auteurs : Michelle BOSQUET ENLOW, Auteur ; Immaculata DE VIVO, Auteur ; Carter R.

NELSON, Auteur Article en page(s) : p.705-718 Langues : Anglais (eng) Mots-clés : Differential susceptibility  maternal depression  sex  telomere  temperament Index. décimale : PER Périodiques Résumé : Individual differences in sensitivity to context are posited to emerge early in development and to influence the effects of environmental exposures on a range of developmental outcomes. The goal of the current study was to examine the hypothesis that temperament characteristics and biological sex confer differential vulnerability to the effects of exposure to maternal depression on telomere length in early childhood. Telomere length has emerged as a potentially important biomarker of current and future health, with possible mechanistic involvement in the onset of various disease states. Participants comprised a community sample of children followed from infancy to age 3 years. Relative telomere length was assessed from DNA in saliva samples collected at infancy, 2 years, and 3 years. Maternal depressive symptoms and the child temperament traits of negative affectivity, surgency/extraversion, and regulation/effortful control were assessed via maternal report at each timepoint. Analyses revealed a 3-way interaction among surgency/extraversion, sex, and maternal depressive symptoms, such that higher surgency/extraversion was associated with shorter telomere length specifically among males exposed to elevated maternal depressive symptoms. These findings suggest that temperament and sex influence children?s susceptibility to the effects of maternal depression on telomere dynamics in early life.
