Caregiving quality modulates neuroendocrine and immunological markers in young children in foster care who have experienced early adversity / Vanessa REINDL in Journal of Child Psychology and Psychiatry, 63-5 (May 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-5 (May 2022) . - p.535-543 Titre : Caregiving quality modulates neuroendocrine and immunological markers in young children in foster care who have experienced early adversity Type de document : Texte imprimé et/ou numérique Auteurs : Vanessa REINDL, Auteur ; Anastasia SCHIPPERS, Auteur ; Klaus TENBROCK, Auteur ; Ann-Katrin JOB, Auteur ; Christian GERLOFF, Auteur ; Arnold LOHAUS, Auteur ; Nina HEINRICHS, Auteur ; Kerstin KONRAD, Auteur Article en page(s) : p.535-543 Langues : Anglais (eng) Mots-clés : Child, Preschool  Dehydroepiandrosterone  Foster Home Care  Humans  Hydrocortisone  Immunoglobulin A, Secretory  Longitudinal Studies  Progesterone  Saliva  Cortisol  Dhea  caregiving  children in foster care  hair steroids  longitudinal  maltreatment  sIgA Index. décimale : PER Périodiques Résumé : BACKGROUND: Early adversity is believed to alter the body's stress-response systems, putting children at increased risk for somatic and mental health problems. However, it remains unclear whether such alterations normalize under improved caregiving experiences. Thus, the goal of the present study was to investigate (a) whether children in foster care show endocrine and immunological alterations relative to children living with their biological families, (b) whether these alterations change over time spent with the foster family, and (c) whether the alterations are modulated by current caregiving experiences. METHODS: A total of 94 children in foster care and 157 biological children, aged two to seven years, took part in a longitudinal study with three assessments conducted over a 12-month study period. At the initial assessment, children lived for an average of 18?months with their current foster families. Children's cortisol, dehydroepiandrosterone (DHEA) and progesterone concentrations and cortisol/DHEA ratios were measured in scalp hair and children's secretory immunoglobulin A (sIgA) levels in saliva. Caregiving quality was assessed based on caregiver-reports and observational measures of caregiver-child interactions. RESULTS: Children in foster care had lower cortisol/DHEA ratios and higher progesterone concentrations than biological children, while no group differences were found for cortisol, DHEA or sIgA. Time spent with the current foster family did not significantly influence the child's endocrine or immunological markers. Importantly, caregiving quality modulated cortisol/DHEA ratios and sIgA concentrations: children in foster care of lower caregiving quality had lower cortisol/DHEA ratios than children in foster care of higher caregiving quality and showed decreasing, rather than increasing, sIgA concentrations across the study period. CONCLUSIONS: Our results indicate that caregiving quality in the foster family may have an important modulating effect on selected indicators of the child's stress response and could thereby mitigate the possible consequences of early childhood adversity.

Effects of Incentives on Families'Long-Term Outcome in a Parenting Program / Nina HEINRICHS in Journal of Clinical Child & Adolescent Psychology, 39-5 (September-October 2010)  

Public ISBD [article]  inJournal of Clinical Child & Adolescent Psychology > 39-5 (September-October 2010) . - p.705-712 Titre : Effects of Incentives on Families'Long-Term Outcome in a Parenting Program Type de document : Texte imprimé et/ou numérique Auteurs : Nina HEINRICHS, Auteur ; Amanda JENSEN-DOSS, Auteur Année de publication : 2010 Article en page(s) : p.705-712 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : To examine the impact of paying for participation in a preventive parenting program on treatment outcomes, 197 families with preschool-aged children were randomized to paid or unpaid conditions. Although both groups improved on nearly all measures, paid families showed less improvement on 3 of 10 variables, including father-reported child prosocial behavior and parenting skills and maternal distress. The interaction between payment and treatment format (individual vs. group) was examined. Compared to unpaid group participants, paid group intervention participants had significantly worse mother and father parenting skills posttreatment, whereas paid individual intervention mothers had significantly better skills. These findings suggest payment may lead to smaller treatment effects, although the bulk of the data point to no impact on outcomes. Given that payment attracts families who would not otherwise receive treatment, this appears to be a viable strategy to recruit families without appreciably impacting outcomes.

Restricted autonomic flexibility in children with social phobia / Julian SCHMITZ in Journal of Child Psychology and Psychiatry, 52-11 (November 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-11 (November 2011) . - p.1203-1211 Titre : Restricted autonomic flexibility in children with social phobia Type de document : Texte imprimé et/ou numérique Auteurs : Julian SCHMITZ, Auteur ; Martina KRAMER, Auteur ; Brunna TUSCHEN-CAFFIER, Auteur ; Nina HEINRICHS, Auteur ; Jens BLECHERT, Auteur Année de publication : 2011 Article en page(s) : p.1203-1211 Langues : Anglais (eng) Mots-clés : Social phobia  children  autonomic flexibility  psychopathology Index. décimale : PER Périodiques Résumé : Background:  Psychophysiological hyperresponsiveness to social-evaluative stress plays a key role in current theories of social phobia (SP). Owing to the early onset of this disorder, the study of children with SP can help to improve etiological models. However, research to date has failed to clarify whether children with SP are physiologically hyperresponsive to stress or not. In addition, the existence of elevated pre-stressor baseline group differences complicates the interpretation of acute stress responses and therefore poses a challenge for this line of research. Drawing on current models of autonomic control to explain the relationship between baseline and stress responding in SP children and healthy controls (HC), we acquired a broad set of autonomic measures in our study. Method:  To index baseline and stress reactivity and to assess autonomic flexibility, we assessed a comprehensive array of sympathetic and parasympathetic measures in SP children (aged 8 to 12 years; n = 30) and healthy control children (HC, n = 26), while exposing them to the Trier Social Stress Test for Children (TSST-C). Results:  At baseline, the SP children showed higher levels of sympathetic (heart rate, electrodermal activity) and lower levels of parasympathetic (respiratory sinus arrhythmia, RSA) activation when compared to the HC children. During the TSST-C, the SP children showed similar HR responses but a limited RSA reactivity and a slower HR recovery relative to the HC children. Conclusion:  Our study extends previous research by showing elevated baseline arousal and comparable stress responding in SP children relative to HC children. In addition, based on the autonomic flexibility model, we provide a potential explanation for the null findings of previous studies during stress. The pattern of elevated baseline heart rates and reduced RSA point to restricted autonomic flexibility in children with SP.
