The biological mechanisms that explain the associations between maternal prenatal depressive symptoms and offspring HPA axis regulation are not yet clear. This pre-registered investigation examines whether patterns of maternal depressive symptoms in pregnancy are associated with infant cortisol reactivity and whether this association is mediated by changes in placental corticotropin-releasing hormone (pCRH).Method:A sample of 174 pregnant women completed assessments in early, mid, and late pregnancy that included standardized measures of depressive symptoms and blood samples for pCRH. Infant cortisol reactivity was assessed at 1 and 6 months of age.Results:Greater increases in maternal depressive symptoms in pregnancy were associated with higher cortisol infant cortisol reactivity at 1 and 6 months. Greater increases in maternal depressive symptoms in pregnancy were associated with greater increases in pCRH from early to late pregnancy which in turn were associated with higher infant cortisol reactivity.Conclusions:Increases in maternal depressive symptoms and pCRH over pregnancy may contribute to higher infant cortisol reactivity. These findings help to elucidate the prenatal biopsychosocial processes contributing to offspring HPA axis regulation early in development.

Second-by-second infant and mother emotion regulation and coregulation processes / Jennifer A. SOMERS in Development and Psychopathology, 34-5 (December 2022)  

Public ISBD [article]  inDevelopment and Psychopathology > 34-5 (December 2022) . - p.1887-1900 Titre : Second-by-second infant and mother emotion regulation and coregulation processes Type de document : Texte imprimé et/ou numérique Auteurs : Jennifer A.

SPINRAD, Auteur Article en page(s) : p.1887-1900 Langues : Anglais (eng) Mots-clés : emotion regulation  Mother × Infant interaction  vagal functioning Index. décimale : PER Périodiques Résumé : Context-appropriate infant physiological functioning may support emotion regulation and mother “infant emotion coregulation. Among a sample of 210 low-income Mexican-origin mothers and their 24-week-old infants, dynamic structural equation modeling (DSEM) was used to examine whether within-infant vagal functioning accounted for between-dyad differences in within-dyad second-by-second emotion regulation and coregulation during free play. Vagal functioning was captured by within-infant mean and variability (standard deviation) of respiratory sinus arrhythmia (RSA) during free play. Infant emotion regulation was quantified as emotional equilibria (within-person mean), volatility (within-person deviation from equilibrium), carryover (how quickly equilibrium is restored following a disturbance), and feedback loops (the extent to which prior affect dampens or amplifies subsequent affect) in positive and negative affect during free play; coregulation was quantified as the influence of one partner's affect on the other's subsequent affect. Among infants with lower RSA variability, positive affect fluctuated around a higher equilibrium, and negative affect fluctuated around a lower equilibrium; these infants exhibited feedback loops where their positive affect dampened their subsequent negative affect. As expected, infants with higher mean RSA exhibited more volatility in positive affect, feedback loops between their positive and negative affect, and stronger mother-driven emotion coregulation. The results highlight differences in simultaneously occurring biological and emotion regulation.

Within-dyad bidirectional relations among maternal depressive symptoms and child behavior problems from infancy through preschool / Sarah G. CURCI in Development and Psychopathology, 35-2 (May 2023)  

Public ISBD [article]  inDevelopment and Psychopathology > 35-2 (May 2023) . - p.547-557 Titre : Within-dyad bidirectional relations among maternal depressive symptoms and child behavior problems from infancy through preschool Type de document : Texte imprimé et/ou numérique Auteurs : Sarah G. CURCI, Auteur ; Jennifer A. SOMERS, Auteur ; Laura K. WINSTONE, Auteur ; Linda J. LUECKEN, Auteur Article en page(s) : p.547-557 Langues : Anglais (eng) Mots-clés : bidirectionality  child behavior problems  depressive symptoms  mother-child dyad  within-dyad Index. décimale : PER Périodiques Résumé : Although dyadic theory focuses on the impact of a mother?s mental health on her own child and the impact of a child?s mental health on their own mother, commonly used statistical approaches are incapable of distinguishing the desired within-dyad processes from between-dyad effects. Using autoregressive latent trajectory modeling with structured residuals, the current study evaluated within-dyad, bidirectional associations between maternal depressive symptoms and child behavior problems from child age 1-4.5 years among a sample of low-income, Mexican American women (N = 322, M age = 27.8) and their children. Women reported on maternal depressive symptoms and child behavior problems during laboratory visits at child age 1, 1.5, 2, 3, and 4.5 years. Results provide novel evidence of child-driven bidirectional association between maternal depressive symptoms and child behavior problems at the within-dyad level as early as child age 1 year and within-person stability in child behavior problems emerging early in life.
