KOSS, Auteur ; Megan R. GUNNAR, Auteur Article en page(s) : p.327-346 Langues : Anglais (eng) Mots-clés : Early adversity  hypothalamic-pituitary-adrenocortical axis  psychopathology Index. décimale : PER Périodiques Résumé : BACKGROUND: Research on early adversity, stress biology, and child development has grown exponentially in recent years. 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.

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 Auteurs : Nicole B. PERRY, Auteur ; Carrie E. DEPASQUALE, Auteur ; Bonny DONZELLA, Auteur ; Megan R. GUNNAR, Auteur Article en page(s) : p.1854-1863 Langues : Anglais (eng) Mots-clés : Adolescent  Humans  Hydrocortisone  Parents  *Problem Behavior  Puberty  Saliva  *Stress, Psychological  *cortisol  *externalizing  *institutions  *internalizing  *puberty  *stress Index. décimale : PER Périodiques Résumé : Megan Gunnar's pubertal stress recalibration hypothesis was supported in a recent study of previously institutionalized (PI) youth such that increases in pubertal stage were associated with increases in cortisol stress reactivity. 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.

Behavior problems in postinstitutionalized internationally adopted children / Megan R. GUNNAR in Development and Psychopathology, 19-1 (Winter 2007)  

Public ISBD [article]  inDevelopment and Psychopathology > 19-1 (Winter 2007) . - p.129-148 Titre : Behavior problems in postinstitutionalized internationally adopted children Type de document : texte imprimé Auteurs : Megan R. GUNNAR, Auteur ; Manfred H.M. VAN DULMEN, Auteur ; THE INTERNATIONAL ADOPTION PROJECT TEAM, Auteur Année de publication : 2007 Article en page(s) : p.129-148 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Predictors and concurrent correlates of childhood-onset and adolescent-onset antisocial behavior were studied in a sample of 165 boys and 151 girls, followed from age 6 to age 15. An integrated general growth mixture model was used to determine the number and shape of developmental trajectories of antisocial behavior exhibited by boys and girls. Associations of these trajectories with trajectories of attention-deficit/hyperactivity (ADH) problems and deviant peer affiliation were examined. A childhood-onset, an adolescent-onset, and a low antisocial behavior trajectory were identified. A minority of the sample (11%), mostly males, followed the childhood-onset trajectory. This trajectory was predicted by prior membership in the high ADH trajectory in childhood. The adolescent-onset trajectory (46%) was associated with increases in friends' antisocial behavior but not with ADH problems. Most females (60%) followed the low antisocial trajectory. A substantial proportion of females, however, followed the childhood (5%) and adolescent-onset trajectories (35%). The male–female ratios in the childhood and adolescent-onset trajectories were similar. The results largely supported theories that distinguish between childhood and adolescent onsets of antisocial behavior, but they did not suggest that boys and girls differ in the age of onset of antisocial behavior.

Behavioral and emotional symptoms of post-institutionalized children in middle childhood / Kristen L. WIIK in Journal of Child Psychology and Psychiatry, 52-1 (January 2011)

GUNNAR, Auteur Année de publication : 2011 Article en page(s) : p.56-63 Langues : Anglais (eng) Mots-clés : International adoption  institutional care  mental health Index. décimale : PER Périodiques Résumé : Background:  Experience in institutional/orphanage care has been linked to increased mental health problems. Research suggests that children adopted from institutions experience specific difficulties related to inattention/overactivity. Evidence of internalizing and conduct problems relative to non-adopted peers has been found in early childhood and early adolescence, but problems may not differ from other adopted children. This study clarifies the understanding of behavioral and emotional symptoms of post-institutionalized (PI) children during middle childhood. Methods:  Eight- to eleven-year-old PI children (n = 68) and two comparison groups, children internationally adopted from foster care (n = 74) and non-adopted children (n = 76), and their parents completed the MacArthur Health and Behavior Questionnaire related to attention-deficit/hyperactivity disorder (ADHD), externalizing, and internalizing symptoms. Group means for symptom level and number of children with symptoms above clinical cutoffs were compared. Results:  PI children displayed an increased level of ADHD symptoms per parent report. PI child and parent report indicated a higher number of PI children above clinical ADHD cutoff. Both groups of internationally adopted (IA) children had higher levels of externalizing symptoms relative to non-adopted children, with parent report indicating higher numbers of IA children above the externalizing clinical threshold. Informants differed in their report of internalizing symptoms. Parents indicated that both IA groups displayed increased internalizing symptom levels and greater numbers above clinical threshold; however, children reported this to be true only for the PI group. Conclusions:  PI children differ from non-adopted peers across symptom domains in middle childhood. Whether these concerns were more broadly associated with international adoption rather than institutional care depended on symptom domain and informant. An understanding of this variability may be beneficial for treatment and intervention.

A brief video-coaching intervention buffers young children's vulnerability to the impact of caregivers’ depressive symptoms: Examination of differential susceptibility / Sihong LIU in Development and Psychopathology, 33-5 (December 2021)

Particularly, the study aimed to determine whether improving caregivers’ responsive parenting through the Filming Interactions to Nurture Development (FIND) intervention would buffer children's biologically embedded vulnerability to caregivers’ depressive symptoms. Data were derived from a randomized controlled trial using pretest–posttest design with low-income families of children aged 4 to 36 months (N = 91). Young children's differential sensitivity was measured using cortisol AUCg during a structured stress paradigm. As hypothesized, children whose cortisol AUCg indicated greater sensitivity to social context exhibited more internalizing and externalizing behaviors in relation to caregivers’ elevated depressive symptoms. Critically, the intervention program was effective in attenuating psychopathology symptoms among the more biologically sensitive children. As proven by rigorous statistical tests, the findings of this study partially supported the differential susceptibility hypotheses, indicating both greater vulnerability to adverse conditions and responsiveness to intervention among children with high levels of cortisol AUCg.
