MADSEN, Auteur Année de publication : 2008 Article en page(s) : p.473-491 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Animal studies reveal that early deprivation impairs regulation of the hypothalamic–pituitary–adrenocortical (HPA) axis, potentially increasing vulnerability to stressors throughout life. To examine early deprivation effects on basal HPA axis activity in humans, basal cortisol levels were examined in 164 internationally adopted children who had experienced varying degrees of preadoption deprivation. Duration of institutional care, age at adoption, and parent ratings of preadoption neglect indexed a latent factor of Deprived Care. Adoption measures of height and weight standardized to World Health Organisation norms indexed a latent factor of Growth Delay that was viewed as another reflection of deprivation. Cortisol samples were collected 3.3–11.6 years postadoption (Md = 7.3 years) at home on 3 days approximately 30 min after wakeup and before bedtime. Both early a.m. levels and the decrease in cortisol across the day were examined. A structural equation model revealed that preadoption Deprived Care predicted Growth Delay at adoption and Growth Delay predicted higher morning cortisol levels and a larger diurnal cortisol decrease.

Risk and protective factors for comorbid internalizing and externalizing problems among economically disadvantaged African American youth / Jingwen LIU in Development and Psychopathology, 29-3 (August 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-3 (August 2017) . - p.1043-1056 Titre : Risk and protective factors for comorbid internalizing and externalizing problems among economically disadvantaged African American youth Type de document : Texte imprimé et/ou numérique Auteurs : Jingwen LIU, Auteur ; Brian MUSTANSKI, Auteur ; Danielle DICK, Auteur ; John BOLLAND, Auteur ; Darlene A. KERTES, Auteur Article en page(s) : p.1043-1056 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Comorbidity of internalizing and externalizing problems and its risk and protective factors have not been well incorporated into developmental research, especially among racial minority youth from high-poverty neighborhoods. The present study identified a latent comorbid factor as well as specific factors underlying internalizing and externalizing problems among 592 African American adolescents living in economically disadvantaged neighborhoods (291 male; M age = 15.9 years, SD = 1.43 years). Stressful life events and racial discrimination were associated with higher comorbid problems, whereas stressful life events and exposure to violence were associated with higher specific externalizing problems. Collective efficacy was associated with both lower specific externalizing problems and lower comorbid problems. Moreover, high collective efficacy buffered the risk effects of stressful life events and racial discrimination on comorbid problems. Our results demonstrated the advantages of latent variable modeling to understanding comorbidity by articulating impacts of risk factors on comorbid and specific components underlying internalizing and externalizing problems. They also highlighted the protective effect of collective efficacy in mitigating risks for these problems. These findings broadly call for more studies on comorbidities in developmental psychopathology among youth from diverse sociocultural backgrounds.
