Serotonin transporter linked polymorphic region (5-HTTLPR) genotype moderates the longitudinal impact of early caregiving on externalizing behavior / Zoë H. BRETT in Development and Psychopathology, 27-1 (February 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-1 (February 2015) . - p.7-18 Titre : Serotonin transporter linked polymorphic region (5-HTTLPR) genotype moderates the longitudinal impact of early caregiving on externalizing behavior Type de document : Texte imprimé et/ou numérique Auteurs : Zoë H. BRETT, Auteur ; Kathryn L. HUMPHREYS, Auteur ; Anna T. SMYKE, Auteur ; Mary Margaret GLEASON, Auteur ; Charles A. NELSON, Auteur ; Charles H. ZEANAH, Auteur ; Nathan A. FOX, Auteur ; Stacy S. DRURY, Auteur Article en page(s) : p.7-18 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We examined caregiver report of externalizing behavior from 12 to 54 months of age in 102 children randomized to care as usual in institutions or to newly created high-quality foster care. At baseline no differences by group or genotype in externalizing were found. However, changes in externalizing from baseline to 42 months of age were moderated by the serotonin transporter linked polymorphic region genotype and intervention group, where the slope for short–short (S/S) individuals differed as a function of intervention group. The slope for individuals carrying the long allele did not significantly differ between groups. At 54 months of age, S/S children in the foster care group had the lowest levels of externalizing behavior, while children with the S/S genotype in the care as usual group demonstrated the highest rates of externalizing behavior. No intervention group differences were found in externalizing behavior among children who carried the long allele. These findings, within a randomized controlled trial of foster care compared to continued care as usual, indicate that the serotonin transporter linked polymorphic region genotype moderates the relation between early caregiving environments to predict externalizing behavior in children exposed to early institutional care in a manner most consistent with differential susceptibility.

The caregiving context in institution-reared and family-reared infants and toddlers in Romania / Anna T. SMYKE in Journal of Child Psychology and Psychiatry, 48-2 (February 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-2 (February 2007) . - p.210–218 Titre : The caregiving context in institution-reared and family-reared infants and toddlers in Romania Type de document : Texte imprimé et/ou numérique Auteurs : Anna T.

Method: Videotaped observations of the child and favorite caregiver in their 'home' environment were coded for caregiving quality, and this was related to child characteristics. Child emotional reactivity was assessed during responses to interactional tasks. Cognitive development was assessed from child responses to the Bayley Scales of Infant Development. Data regarding problem behaviors and competence were obtained from caregiver report. Children reared in institutions were compared on all of these measures to never institutionalized children to assist gauging degree of impairment. Results: Children raised in institutions demonstrated marked delays in cognitive development, poorer physical growth, and marked deficits in competence. Individual differences in caregiving environment were associated with cognitive development, competence, and negative behavior among these young children being reared in institutions. Conclusions: These data confirm previous findings regarding deficits associated with institutional care and extend our understanding of the impact of individual differences in caregiving quality on the development of young children in institutions.

The effects of foster care intervention on socially deprived institutionalized children's attention and positive affect: results from the BEIP study / Melissa M. GHERA in Journal of Child Psychology and Psychiatry, 50-3 (March 2009)

Methods: Institutionalized children were randomized to enter foster care or to remain under institutional care. Subsequently, the institutionalized and foster care groups, along with a community-based comparison group, were evaluated on emotion tasks at 30 and 42 months of age. Behaviors reflecting positive and negative affect and attention were coded from videotapes. Results: Data indicated that at both age points, children who received the foster care intervention showed higher levels of attention and positive affect compared to children who remained institutionalized. Compared to the community sample, children in the foster care intervention showed higher levels of attention to the emotion-eliciting tasks at 42 months of age. Conclusions: The results of this randomized trial demonstrate the impact of a family-based intervention on the development of attention and positive affect.
