Infant EEG and temperament negative affectivity: Coherence of vulnerabilities to mothers' perinatal depression / Cara M. LUSBY in Development and Psychopathology, 28-4 pt1 (November 2016)  

Public ISBD [article]  inDevelopment and Psychopathology > 28-4 pt1 (November 2016) . - p.895-911 Titre : Infant EEG and temperament negative affectivity: Coherence of vulnerabilities to mothers' perinatal depression Type de document : Texte imprimé et/ou numérique Auteurs : Cara M. LUSBY, Auteur ; Sherryl H. GOODMAN, Auteur ; Ellen W. YEUNG, Auteur ; Martha Ann BELL, Auteur ; Zachary N. STOWE, Auteur Article en page(s) : p.895-911 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Associations between infants' frontal EEG asymmetry and temperamental negative affectivity (NA) across infants' first year of life and the potential moderating role of maternal prenatal depressive symptoms were examined prospectively in infants (n = 242) of mothers at elevated risk for perinatal depression. In predicting EEG, in the context of high prenatal depressive symptoms, infant NA and frontal EEG asymmetry were negatively associated at 3 months of age and positively associated by 12 months of age. By contrast, for low depression mothers, infant NA and EEG were not significantly associated at any age. Postnatal depressive symptoms did not add significantly to the models. Dose of infants' exposure to maternal depression mattered: infants exposed either pre- or postnatally shifted from a positive association at 3 months to a negative association at 12 months; those exposed both pre- and postnatally shifted from a negative association at 3 months to a positive association at 12 months. Prenatal relative to postnatal exposure did not matter for patterns of association between NA and EEG. The findings highlight the importance of exploring how vulnerabilities at two levels of analysis, behavioral and psychophysiological, co-occur over the course of infancy and in the context of mothers' depressive symptomatology.

Physiological attunement in mother–infant dyads at clinical high risk: The influence of maternal depression and positive parenting / Cassandra L. HENDRIX in Development and Psychopathology, 30-2 (May 2018)  

Public ISBD [article]  inDevelopment and Psychopathology > 30-2 (May 2018) . - p.623-634 Titre : Physiological attunement in mother–infant dyads at clinical high risk: The influence of maternal depression and positive parenting Type de document : Texte imprimé et/ou numérique Auteurs : Cassandra L. HENDRIX, Auteur ; Zachary N. STOWE, Auteur ; D. Jeffrey NEWPORT, Auteur ; Patricia A. BRENNAN, Auteur Article en page(s) : p.623-634 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : A growing number of research studies have examined the intradyadic coregulation (or attunement) of hypothalamus–pituitary–adrenal axis functioning in mothers and their children. However, it is unclear how early this coregulation may be present in dyads at clinical high risk and whether certain factors, such as maternal depression or positive parenting, are associated with the strength of this coregulation. The present study examined cortisol attunement within mother–infant dyads in a high-risk sample of 233 mothers who received treatment for psychiatric illness during pregnancy and whose infants were 6 months old at the study visit. Results showed that maternal and infant cortisol covaried across four time points that included a stressor paradigm and a mother–infant interaction task. Greater maternal positive affect, but not depression, predicted stronger cortisol attunement. In addition, infants’ cortisol level following separation from the mother predicted mothers’ cortisol level at the next time point. Mothers’ cortisol level following the separation and the laboratory stress paradigm predicted infants’ cortisol levels at each successive time point, over and above infants’ own cortisol at the previous time point. These findings suggest that maternal and infant cortisol levels influence one another in a bidirectional fashion that may be temporally and context dependent.

Physiological regulation in infants of women with a mood disorder: examining associations with maternal symptoms and stress / Katrina C. JOHNSON in Journal of Child Psychology and Psychiatry, 55-2 (February 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-2 (February 2014) . - p.191-198 Titre : Physiological regulation in infants of women with a mood disorder: examining associations with maternal symptoms and stress Type de document : Texte imprimé et/ou numérique Auteurs : Katrina C. JOHNSON, Auteur ; Patricia A. BRENNAN, Auteur ; Zachary N. STOWE, Auteur ; Ellen LEIBENLUFT, Auteur ; D. Jeffrey NEWPORT, Auteur Article en page(s) : p.191-198 Langues : Anglais (eng) Mots-clés : Bipolar  depression  RSA  heart rate  vagal  stress  infants  human Index. décimale : PER Périodiques Résumé : Background The offspring of mothers with mood disorders may evidence increased behavioral problems as early as preschool; however, no study to date has examined psychophysiological characteristics during infancy, particularly among offspring of mothers diagnosed with bipolar disorder. Elucidating psychobiological mechanisms of risk early in development is critical to inform prevention and early intervention efforts. Method This study compared physiological and behavioral responsivity in 6-month-old infants (N = 329) of mothers with lifetime histories of bipolar disorder (BD, n = 44), major depressive disorder (MDD, n = 244), or no history of Axis I disorders (CTL, n = 41). Infant respiratory sinus arrhythmia (RSA) was measured in a laboratory stressor paradigm. Measures of infant affect and behavior during mother–infant interaction, current maternal depressive symptoms, and exposure to stressful life events were examined with respect to diagnostic group and RSA. Results Groups did not differ in baseline RSA or infant affect measures. However, during the stressor task, infants of mothers with BD evidenced increases in RSA, while infants of MDD and CTL mothers evidenced decreases in RSA. Though levels of postnatal stress and current levels of maternal depressive symptoms differed among groups, neither of these factors predicted infant psychophysiological responses. Conclusions At 6 months of age, infants of motrs with BD show differences in psychophysiological regulation. These differences cannot be accounted for by perinatal outcome, current maternal depressive symptoms, or exposure to stressful life events, and thus may reflect endophenotypic markers of psychopathological risk.
