Early life stress and development: potential mechanisms for adverse outcomes / Karen E. SMITH in Journal of Neurodevelopmental Disorders, 12 (2020)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 12 (2020) Titre : Early life stress and development: potential mechanisms for adverse outcomes Type de document : texte imprimé Auteurs : Karen E. SMITH, Auteur ; Seth D. POLLAK, Auteur Langues : Anglais (eng) Mots-clés : Adverse Childhood Experiences  Amygdala  Child  Humans  Hypothalamo-Hypophyseal System  Pituitary-Adrenal System  Stress, Psychological  Developmental disorders  Early adversity  Early life stress  Neurobiological development Index. décimale : PER Périodiques Résumé : BACKGROUND: Chronic and/or extreme stress in early life, often referred to as early adversity, childhood trauma, or early life stress, has been associated with a wide range of adverse effects on development. However, while early life stress has been linked to negative effects on a number of neural systems, the specific mechanisms through which early life stress influences development and individual differences in children's outcomes are still not well understood. MAIN TEXT: The current paper reviews the existing literature on the neurobiological effects of early life stress and their ties to children's psychological and behavioral development. CONCLUSIONS: Early life stress has persistent and pervasive effects on prefrontal-hypothalamic-amygdala and dopaminergic circuits that are at least partially mediated by alterations in hypothalamic-pituitary-adrenal axis function. However, to date, this research has primarily utilized methods of assessment that focus solely on children's event exposures. Incorporating assessment of factors that influence children's interpretation of stressors, along with stressful events, has the potential to provide further insight into the mechanisms contributing to individual differences in neurodevelopmental effects of early life stress. This can aid in further elucidating specific mechanisms through which these neurobiological changes influence development and contribute to risk for psychopathology and health disorders.

Sympathetic nervous system dominance during stress recovery mediates associations between stress sensitivity and social anxiety symptoms in female adolescents / Tiffany C. HO in Development and Psychopathology, 32-5 (December 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-5 (December 2020) . - p.1914-1925 Titre : Sympathetic nervous system dominance during stress recovery mediates associations between stress sensitivity and social anxiety symptoms in female adolescents Type de document : texte imprimé Auteurs : Tiffany C.

No study, however, has systematically examined which aspects of autonomic nervous system function mediate likely links between stress sensitivity and social anxiety symptoms in adolescents. Here, we assessed 163 adolescents (90 females; 12.29 ± 1.39 years) with respect to life stress and social anxiety symptoms, and measured respiratory sinus arrhythmia (RSA) and skin conductance levels (SCL) during a psychosocial stress paradigm. We operationalized stress sensitivity as the residual variance in subjective stress severity after accounting for objective severity and changes in autonomic regulation using standardized change scores in RSA and SCL. In females only, stress sensitivity and social anxiety symptoms were significantly correlated with each other (p < .001) and with autonomic regulation during both reactivity and recovery (all ps < 0.04). Further, sympathetic nervous system dominance during recovery specifically mediated associations between stress sensitivity and social anxiety symptoms (B = 1.06, 95% CI: 0.02-2.64). In contrast, in males, stress sensitivity, autonomic regulation during reactivity or recovery, and social anxiety symptoms were not significantly associated (all ps > 0.1). We interpret these results in the context of psychobiological models of SAD and discuss implications for interventions targeting autonomic processes.

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 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.

Environmental determinants of physiological reactivity to stress: The interacting effects of early life deprivation, caregiving quality, and stressful life events / Mark WADE in Development and Psychopathology, 32-5 (December 2020)

Here, we used data from a longitudinal randomized controlled trial of foster care for institutionally reared children to examine whether caregiving quality and stressful life events (SLEs) in early adolescence (age 12) influence patterns of hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) reactivity. Controlling for the effect of institutional care, higher caregiving quality at age 12 was associated with heightened cortisol and SNS reactivity. However, moderation analysis revealed that the latter effect was only observed among never-institutionalized children, whereas ever-institutionalized children demonstrated a persistently blunted SNS response regardless of recent caregiving quality. Among institutionally reared children, SLEs interacted with prior random assignment to foster care, such that those placed in foster care early in development had a SNS response that approximated never-institutionalized children when SLEs at age 12 were low. In contrast, SNS reactivity was persistently blunted among those with prolonged deprivation, regardless of recent SLEs. Early-life deprivation is associated with persistent blunting of stress response systems, but normalization may be achievable if SLEs are limited following placement into enriched family-based care.

Fathers Raising Children on the Autism Spectrum: Lower Stress and Higher Self-Efficacy Following SMS (Text2dads) Intervention / Chris D. MAY in Journal of Autism and Developmental Disorders, 52-1 (January 2022)

Fathers (N = 184) were recruited through autism services across Australia. Participants received messages focusing on five domains: (a) relationships with parenting partner; (b) formal support; (c) father-child interaction; (d) understanding autism; and, (e) coping. Surveys explored parenting stress, co-parenting quality and autism-specific parenting self-efficacy. Eighty-eight percent completed the program, 43.6% completed pre and post surveys. There was significant reduction in parenting stress (p < .01) and increase in autism-specific parenting self-efficacy (p < .01). Effect sizes indicate these may be clinically meaningful. This highly scalable intervention has potential to influence factors that shape and sustain relationships fathers share with their children on the autism spectrum, families and services.
