Child maltreatment severity and sleep variability predict mother–infant RSA coregulation / Samantha M. BROWN in Development and Psychopathology, 33-5 (December 2021)

Child maltreatment and sleep variability may reflect high-risk caregiving, but it is unknown whether they confer vulnerability for poorer mother–infant parasympathetic coordination. The aim of this study was to examine mother–infant coregulation of respiratory sinus arrhythmia (RSA) in relation to child maltreatment severity and night-to-night sleep variability in 47 low-income mother–infant dyads. Maternal and infant sleep was assessed with actigraphy and daily diaries for 7 nights followed by a mother–infant still-face procedure during which RSA was measured. Higher maltreatment severity was associated with weakened concordance in RSA coregulation related to the coupling of higher mother RSA with lower infant RSA, suggesting greater infant distress and lower maternal support. In addition, higher infant sleep variability was associated with infants’ lower mean RSA and concordance in lagged RSA coregulation such that lower maternal RSA predicted lower infant RSA across the still-face procedure, suggesting interrelated distress. The findings indicate that adverse caregiving environments differentially impact regulatory patterns in mother–infant dyads, which may inform modifiable health-risk behaviors as targets for future intervention.

Parental buffering in the context of poverty: positive parenting behaviors differentiate young children's stress reactivity profiles / Samantha M. BROWN in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1778-1787 Titre : Parental buffering in the context of poverty: positive parenting behaviors differentiate young children's stress reactivity profiles Type de document : Texte imprimé et/ou numérique Auteurs : Samantha M. BROWN, Auteur ; Lisa J. SCHLUETER, Auteur ; Eliana HURWICH-REISS, Auteur ; Julia DMITRIEVA, Auteur ; Elly MILES, Auteur ; Sarah E.

Positive parenting buffers children from HPA axis reactivity, yet this has primarily been documented among families not experiencing poverty. We tested the theorized power of positive parenting in 124 parent-child dyads recruited from Early Head Start (Mage = 25.21 months) by examining child cortisol trajectories using five samples collected across a standardized stress paradigm. Piecewise latent growth models revealed that positive parenting buffered children's stress responses when controlling for time of day, last stress task completed, and demographics. Positive parenting also interacted with income such that positive parenting was especially protective for cortisol reactivity in families experiencing greater poverty. Findings suggest that positive parenting behaviors are important for protecting children in families experiencing low income from heightened or prolonged physiologic stress reactivity to an acute stressor.
