Associations between multisystem stress reactivity and peer nominated aggression in early childhood vary by sex / Melissa J. HAGAN in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1888-1898 Titre : Associations between multisystem stress reactivity and peer nominated aggression in early childhood vary by sex Type de document : Texte imprimé et/ou numérique Auteurs : Melissa J.

This study tested associations between sex-specific patterns of stress responses across the sympathetic nervous system (SNS) and hypothalamic-pituitary-adrenal (HPA) axis and peer nominations of aggression among 271 kindergarten children (Mean age = 5.32 years; 52% Female; 44% White). Upon entry to kindergarten, children participated in a multidomain standardized stress paradigm. Changes in pre-ejection period (PEP) and salivary cortisol were assessed. On a separate day, children provided peer ratings of physical and relational aggression in a standardized interview. As expected, there was a significant three-way interaction between PEP, cortisol reactivity, and sex, but only for physical aggression. Among boys, cortisol reactivity was positively associated with physical aggression only for those with higher SNS reactivity. Findings suggest that for boys, asymmetrical and symmetrical HPA/SNS reactivity may be associated with lower and higher risk for peer-directed physical aggression, respectively. Understanding the complex associations between multisystem physiology, child sex and peer-directed aggression in early childhood may offer insight into individual differences underlying the emergence of behavioral dysregulation in early peer contexts.

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.
