Annual Research Review: Early adversity, the hypothalamic-pituitary-adrenocortical axis, and child psychopathology / K. J. KOSS in Journal of Child Psychology and Psychiatry, 59-4 (April 2018)

J. KOSS, Auteur ; M. R.

FINDINGS: We review the current evidence for the hypothalamic-pituitary-adrenocortical (HPA) axis as a stress-mediating mechanism between various forms of childhood adversity and psychopathology. We begin with a review of the neurobiology of the axis and evidence for relations between early adversity-HPA axis activity and HPA axis activity-psychopathology, as well as discuss the role of regulatory mechanisms and sensitive periods in development. CONCLUSIONS: We call attention to critical gaps in the literature to highlight next steps in this research including focus on developmental timing, sex differences, stress buffering, and epigenetic regulation. A better understanding of individual differences in the adversity-HPA axis-psychopathology associations will require continued work addressing how multiple biological and behavioral systems work in concert to shape development.

A Preliminary, Randomized-Controlled Trial of Mindfulness and Game-Based Executive Function Trainings to Promote Self-Regulation in Internationally-Adopted Children / J. M. LAWLER in Development and Psychopathology, 31-4 (October 2019)  

Public ISBD [article]  inDevelopment and Psychopathology > 31-4 (October 2019) . - p.1513-1525 Titre : A Preliminary, Randomized-Controlled Trial of Mindfulness and Game-Based Executive Function Trainings to Promote Self-Regulation in Internationally-Adopted Children Type de document : Texte imprimé et/ou numérique Auteurs : J. M. LAWLER, Auteur ; E. A. ESPOSITO, Auteur ; C. M. DOYLE, Auteur ; M. R.

The current study uses a stratified, randomized, controlled trial to evaluate the effects of mindfulness-based and executive function trainings (EFTs) on internationally adopted (IA) children's self-regulation, including effortful/inhibitory control, attention, delay of gratification, and emotion-regulation. IA children ages 6-10 years were randomized into mindfulness training (MT), EFT, or no intervention (NI) groups. The MT and EFT groups attended 12 one-hour group sessions. Ninety-six children (MT, n = 33; EFT, n = 32; NI, n = 31) completed the study and were tested on computerized and non-computerized measures of self-regulation. Compared with the NI group, the MT group improved delay of gratification, and the EFT group improved inhibitory control and selective attention. There was no effect of either intervention on emotion regulation. MTs and EFTs show promise for improving self-regulation in IA children.

Pubertal recalibration of cortisol reactivity following early life stress: a cross-sectional analysis / Carrie E. DEPASQUALE in Journal of Child Psychology and Psychiatry, 60-5 (May 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-5 (May 2019) . - p.566-575 Titre : Pubertal recalibration of cortisol reactivity following early life stress: a cross-sectional analysis Type de document : Texte imprimé et/ou numérique Auteurs : Carrie E. DEPASQUALE, Auteur ; B. DONZELLA, Auteur ; M. R. GUNNAR, Auteur Article en page(s) : p.566-575 Langues : Anglais (eng) Mots-clés : Stress  endocrinology  institutions  puberty Index. décimale : PER Périodiques Résumé : BACKGROUND: Children adopted from orphanages or other such institutions tend to display blunted reactivity to stressors - even years after arriving in their generally supportive and highly resourced postadoption homes. Puberty, a proposed sensitive period for environmental influences on stress-mediating systems, may provide an opportunity for postinstitutionalized children to recalibrate stress response systems in accordance with their now more supportive living situations. METHODS: This cross-sectional study examined the hypothalamic-pituitary-adrenocortical (HPA)-axis reactivity of 280 children ages 7 through 14 years; 122 children were adopted from institutions in 14 countries between the ages of 6 months and 5 years, after spending an average of 95% of their lives in institutional care, and 158 children of similarly high socioeconomic status in their biological families served as the nonadopted comparison group. All of the children were assessed by nurses for Tanner stage and, on a different day, completed the Trier Social Stress Test for Children. RESULTS: Using a linear mixed-effects model and seven measures of salivary cortisol, results indicated that early-pubertal postinstitutionalized children showed blunted HPA axis reactivity compared to nonadopted children, but mid/late-pubertal postinstitutionalized children displayed higher reactivity similar to the nonadopted comparison children. CONCLUSIONS: This is the first evidence of possible pubertal recalibration of HPA axis reactivity to a psychosocial stressor in postinstitutionalized children, which provides a promising avenue for future research regarding the protective factors of the postadoption environment and subsequent physiological, behavioral, and psychopathological outcomes.
