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 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.

School-age social behavior and pragmatic language ability in children with prenatal serotonin reuptake inhibitor exposure / Erica L. SMEARMAN in Development and Psychopathology, 32-1 (February 2020)

We prospectively followed a cohort of mother-child dyads from pregnancy through early elementary school (N = 178), and obtained maternal and alternate-caregiver ratings of behaviors related to ASD (N = 137), as well as direct, gold-standard assessments of child ASD symptoms and pragmatic language among dyads who experienced prenatal depression and either took SRIs or were medication free during pregnancy (N = 44). Prenatal SRI exposure was related to maternal ratings of ASD-related behaviors (beta = 0.24 95% confidence interval; CI [0.07, 0.48]), and, among boys, alternative caregiver ratings (males-only beta = 0.28 95% CI [0.02, 0.55], females-only beta = -0.21 95% CI [-0.63, 0.08]). However, results of our direct assessments suggest an association between SRI exposure and reduced pragmatic language scores (beta = -0.27, 95% CI [-0.53, -0.01], but not ASD (Autism Diagnostic Observation Schedule beta = 0.14 95% CI [-0.15, 0.41]; Social Responsiveness Scale beta = 0.08 95% CI [-0.25, 0.40]). These discrepancies point to issues regarding how ASD is assessed, and the possibility that SRIs may be more strongly associated with language or other broader behaviors that coincide with ASD. Larger prospective studies that incorporate thorough, gold-standard assessments of ASD, language, and other ASD-related behaviors are needed.
