Associations between stress reactivity and behavior problems for previously institutionalized youth across puberty / Nicole B. PERRY in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1854-1863 Titre : Associations between stress reactivity and behavior problems for previously institutionalized youth across puberty Type de document : Texte imprimé et/ou numérique Auteurs : Nicole B.

This work provides evidence that puberty may open up a window of recalibration for PI youth, resulting in a shift from a blunted to a more typical cortisol stress response. Using the same sample (N = 132), the current study aimed to elucidate whether increases in cortisol are associated with increases in adaptive functioning or whether they further underlie potential links to developmental psychopathology. Specifically, we examined the bidirectional associations between cortisol stress reactivity and both internalizing and externalizing symptoms across three timepoints during the pubertal period. Youth reported on their own internalizing symptoms and parents reported on youths' externalizing symptoms. Cortisol reactivity was assessed during the Trier social stress test. Analyses revealed no associations between cortisol reactivity and externalizing symptoms across puberty for PI youth. However, longitudinal bidirectional associations did emerge for internalizing symptoms such that increases in cortisol reactivity predicted increases in internalizing symptoms and increases in internalizing symptoms predicted increases in cortisol reactivity. Findings suggest that recalibrating to more normative levels of cortisol reactivity may not always be associated with adaptive outcomes for PI youth.

Differential brain activity as a function of social evaluative stress in early adolescence: Brain function and salivary cortisol / Max P. HERZBERG in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1926-1936 Titre : Differential brain activity as a function of social evaluative stress in early adolescence: Brain function and salivary cortisol Type de document : Texte imprimé et/ou numérique Auteurs : Max P. HERZBERG, Auteur ; Ruskin H. HUNT, Auteur ; Kathleen M. THOMAS, Auteur ; Megan R.

These differences may be especially critical during adolescence, which is characterized by opportunities for healthy development and increased susceptibility to the development of psychopathology. While the neural correlates of the psychosocial stress response have been investigated in adults, these links have not been explored during development. Using a new task, the Minnesota Imaging Stress Test in Children (MISTiC), differences in activation are found in fusiform gyrus, superior frontal gyrus, insula, and anterior cingulate cortex when comparing a stressful math task to a nonstressful math task. The MISTiC task successfully elicits cortisol responses in a similar proportion of adolescents as in behavioral studies while collecting brain imaging data. Cortisol responders and nonresponders did not differ in their perceived stress level or behavioral performance during the task despite differences in neuroendocrine function. Future research will be able to leverage the MISTiC task for many purposes, including probing associations between individual differences in stress responses with environmental conditions, personality differences, and the development of psychopathology.

Early adversity and children's regulatory deficits: Does postadoption parenting facilitate recovery in postinstitutionalized children? / Kalsea J. KOSS in Development and Psychopathology, 32-3 (August 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-3 (August 2020) . - p.879-896 Titre : Early adversity and children's regulatory deficits: Does postadoption parenting facilitate recovery in postinstitutionalized children?

GUNNAR, Auteur Article en page(s) : p.879-896 Langues : Anglais (eng) Mots-clés : early adversity  executive function  international adoption  parenting  regulation Index. décimale : PER Périodiques Résumé : Children reared in orphanages typically experience the lack of stable, reliable caregivers and are at increased risk for deficits in regulatory abilities including difficulties in inhibitory control, attention, and emotion regulation. Although adoption results in a radical shift in caregiving quality, there remains variation in postadoption parenting, yet little research has examined postadoption parenting that may promote recovery in children experiencing early life adversity in the form of institutional care. Participants included 93 postinstitutionalized children adopted between 15 and 36 months of age and 52 nonadopted same-aged peers. Parenting was assessed four times during the first 2 years postadoption (at 2, 8, 16, and 24 months postadoption) and children's regulation was assessed at age 5 (M age = 61.68 months) and during kindergarten (M age = 71.55 months). Multiple parenting dimensions including sensitivity/responsiveness, structure/limit setting, and consistency in routines were examined. Both parental sensitivity and structure moderated the effect of preadoption adversity on children's emotion regulation while greater consistency was associated with better inhibitory control and fewer attention problems. Results support the notion that postadoption parenting during toddlerhood and the early preschool years promotes better regulation skills following early adversity.

Life stress and cortisol reactivity: An exploratory analysis of the effects of stress exposure across life on HPA-axis functioning / Ethan S. YOUNG in Development and Psychopathology, 33-1 (February 2021)

Life stress can potentially alter regulation of the HPA axis and has been associated with poorer physical and mental health. Little, however, is known about the relative influence of stressors that are encountered at different developmental periods on acute stress reactions in adulthood. In this study, we explored three models of the influence of stress exposure on cortisol reactivity to a modified version of the Trier Social Stress Test (TSST) by leveraging 37 years of longitudinal data in a high-risk birth cohort (N = 112). The cumulative stress model suggests that accumulated stress across the lifespan leads to dysregulated reactivity, whereas the biological embedding model implicates early childhood as a critical period. The sensitization model assumes that dysregulation should only occur when stress is high in both early childhood and concurrently. All of the models predicted altered reactivity, but do not anticipate its exact form. We found support for both cumulative and biological embedding effects. However, when pitted against each other, early life stress predicted more blunted cortisol responses at age 37 over and above cumulative life stress. Additional analyses revealed that stress exposure in middle childhood also predicted more blunted cortisol reactivity.
