Growth delay as an index of allostatic load in young children: Predictions to disinhibited social approach and diurnal cortisol activity / Anna E. JOHNSON in Development and Psychopathology, 23-3 (August 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-3 (August 2011) . - p.859-871 Titre : Growth delay as an index of allostatic load in young children: Predictions to disinhibited social approach and diurnal cortisol activity Type de document : Texte imprimé et/ou numérique Auteurs : Anna E. JOHNSON, Auteur ; Jacqueline BRUCE, Auteur ; Amanda R. TARULLO, Auteur ; Megan R. GUNNAR, Auteur Année de publication : 2011 Article en page(s) : p.859-871 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The goal of this study was to examine whether growth delay can serve as an index of allostatic load during early development, as it is well known that the activity of stress-mediating systems inhibits growth. The participants were children adopted internationally from institutional care (n = 36), children adopted internationally from foster care (n = 26), and nonadopted children (n = 35). For the adopted children, height for age and weight for height were assessed at adoption; for all children, disinhibited social approach (DSA; termed elsewhere as “indiscriminate friendliness”) and diurnal cortisol were assessed at 6–8 years (M = 6.9 years). For internationally adopted children in general, and postinstitutionalized children specifically, linear growth delay assessed at the time of adoption was associated with more dysregulated behavior in response to an unfamiliar adult (i.e., greater DSA) and a more dysregulated diurnal cortisol rhythm (i.e., higher late afternoon and evening values). Further, among the most growth-delayed children, higher cortisol levels later in the day were correlated with DSA. The potential for using growth delay as an allostatic load indicator and the possible problems and limitations in its use in child populations are discussed.

Risk-taking and sensation-seeking propensity in postinstitutionalized early adolescents / Michelle M. LOMAN in Journal of Child Psychology and Psychiatry, 55-10 (October 2014)

Although these problems have been well described, the related adolescent behaviors of risk-taking and sensation-seeking have not yet been explored in this population. This study examined risk-taking and sensation-seeking propensity, and associations with conduct problems and depressive symptoms, in early adolescents who were adopted as young children from institutional care. Methods Risk-taking and sensation-seeking propensities of 12- and 13-year-old postinstitutionalized (PI; n = 54) adolescents were compared with two groups: youth who were internationally adopted early from foster care (PFC; n = 44) and nonadopted youth (NA; n = 58). Participants were recruited to equally represent pre/early- and mid/late-pubertal stages within each group. Participants completed the youth version of the Balloon Analogue Risk Task (Lejuez et al., ) and the Sensation-Seeking Scale for Children (Russo et al., ). Parents completed clinical ratings of participants' conduct problems and depressive symptoms.

The effect of early deprivation on executive attention in middle childhood / Michelle M. LOMAN in Journal of Child Psychology and Psychiatry, 54-1 (January 2013)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 54-1 (January 2013) . - 37-45 Titre : The effect of early deprivation on executive attention in middle childhood Type de document : Texte imprimé et/ou numérique Auteurs : Michelle M. LOMAN, Auteur ; Anna E. JOHNSON, Auteur ; Alissa WESTERLUND, Auteur ; Seth D. POLLAK, Auteur ; Charles A. III NELSON, Auteur ; Megan R. GUNNAR, Auteur Article en page(s) : 37-45 Langues : Anglais (eng) Mots-clés : Attention  event-related potentials  executive function  international adoption  institutional care Index. décimale : PER Périodiques Résumé : Background: Children reared in deprived environments, such as institutions for the care of orphaned or abandoned children, are at increased risk for attention and behavior regulation difficulties. This study examined the neurobehavioral correlates of executive attention in post institutionalized (PI) children. Methods: The performance and event-related potentials (ERPs) of 10- and 11-year-old internationally adopted PI children on two executive attention tasks, Go/No-go and Flanker, were compared with two groups: children internationally adopted early from foster care (PF) and nonadopted children (NA). Results: Behavioral measures suggested problems with sustained attention, with PIs performing more poorly on Go trials and not on No-go trials of the Go/No-go and made more errors on both congruent and incongruent trials on the Flanker. ERPs suggested differences in inhibitory control and error monitoring, as PIs had smaller N2 amplitude on Go/No-go and smaller error-related negativity on Flanker. Conclusions: This pattern of results raises questions regarding the nature of attention difficulties for PI children. The behavioral errors are not specific to executive attention and instead likely reflect difficulties in overall sustained attention. The ERP results are consistent with neural activity related to deficits in inhibitory control (N2) and error monitoring (error-related negativity). Questions emerge regarding the similarity of attention regulatory difficulties in PIs to those experienced by non-PI children with ADHD.
