Early caregiving quality predicts consistency of competent functioning from middle childhood to adolescence following early psychosocial deprivation / Katherine L. GUYON-HARRIS in Development and Psychopathology, 33-1 (February 2021)

Removal from institutional care and placement into families can promote recovery. However, little is known about how positive outcomes are sustained across adolescence among children with histories of severe deprivation. The present study examined the caregiving conditions that are associated with attaining and maintaining competent functioning (i.e., outcomes within typical levels) from middle childhood to adolescence following exposure to early institutional care. The participants included children with and without a history of institutional care who had competence assessed at ages 8, 12, and 16 years across seven domains: family relationships, peer relationships, academic performance, physical health, mental health, substance use (ages 12 and 16 years only), and risk-taking behavior. The participants were grouped based on whether they were always versus not always competent and never versus ever competent at ages 8 through 16 years. Adolescents with a history of institutional care were less likely to be consistently competent than those who were family reared. Among those who were exposed to early institutional rearing, maintaining competent functioning from 8 to 16 years was associated with spending less time in institutions and receiving higher-quality caregiving early in life. Ensuring high quality early caregiving may promote competent functioning following early deprivation.

Evidence for sex differences in fetal programming of physiological stress reactivity in infancy / Florin TIBU in Development and Psychopathology, 26-4 (Part 1) (November 2014)  

Public ISBD [article]  inDevelopment and Psychopathology > 26-4 (Part 1) (November 2014) . - p.879-888 Titre : Evidence for sex differences in fetal programming of physiological stress reactivity in infancy Type de document : Texte imprimé et/ou numérique Auteurs : Florin TIBU, Auteur ; Jonathan HILL, Auteur ; Helen SHARP, Auteur ; Kate MARSHALL, Auteur ; Vivette GLOVER, Auteur ; Andrew PICKLES, Auteur Année de publication : 2014 Article en page(s) : p.879-888 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Associations between low birth weight and prenatal anxiety and later psychopathology may arise from programming effects likely to be adaptive under some, but not other, environmental exposures and modified by sex differences. If physiological reactivity, which also confers vulnerability or resilience in an environment-dependent manner, is associated with birth weight and prenatal anxiety, it will be a candidate to mediate the links with psychopathology. From a general population sample of 1,233 first-time mothers recruited at 20 weeks gestation, a sample of 316 stratified by adversity was assessed at 32 weeks and when their infants were aged 29 weeks (N = 271). Prenatal anxiety was assessed by self-report, birth weight from medical records, and vagal reactivity from respiratory sinus arrhythmia during four nonstressful and one stressful (still-face) procedure. Lower birth weight for gestational age predicted higher vagal reactivity only in girls (interaction term, p = .016), and prenatal maternal anxiety predicted lower vagal reactivity only in boys (interaction term, p = .014). These findings are consistent with sex differences in fetal programming, whereby prenatal risks are associated with increased stress reactivity in females but decreased reactivity in males, with distinctive advantages and penalties for each sex.

Sex differences in the associations between vagal reactivity and oppositional defiant disorder symptoms / Pablo VIDAL-RIBAS in Journal of Child Psychology and Psychiatry, 58-9 (September 2017)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 58-9 (September 2017) . - p.988-997 Titre : Sex differences in the associations between vagal reactivity and oppositional defiant disorder symptoms Type de document : Texte imprimé et/ou numérique Auteurs : Pablo VIDAL-RIBAS, Auteur ; Andrew PICKLES, Auteur ; Florin TIBU, Auteur ; Helen SHARP, Auteur ; Jonathan HILL, Auteur Article en page(s) : p.988-997 Langues : Anglais (eng) Mots-clés : Vagal reactivity  oppositional defiant disorder  irritability  headstrong  sex differences Index. décimale : PER Périodiques Résumé : Background Vagal reactivity to stress in children has been associated with future psychiatric outcomes. However, results have been mixed possibly because these effects are in opposite direction in boys and girls. These sex differences are relevant in the context of development of psychopathology, whereby the rates of psychiatric disorders differ by sex. In this study, we aimed to examine the association between vagal reactivity, assessed as a reduction in respiratory sinus arrhythmia (RSA) in response to a challenge, and the development of future oppositional defiant disorder (ODD) symptoms in boys and girls. In addition, we examine the specific associations with ODD symptom dimensions, named irritability and headstrong. We hypothesized that increased vagal reactivity was associated with increased ODD symptoms in girls and a reduction in ODD symptoms in boys. Methods Participants were members of the Wirral Child Health and Development Study, a prospective epidemiological longitudinal study of 1,233 first-time mothers recruited at 20 weeks’ gestation. RSA during four nonstressful and one stressful (still-face) procedures was assessed when children were aged 29 weeks in a sample stratified by adversity (n = 270). Maternal reports of ODD symptoms were collected when children were 2.5 years old (n = 253), 3.5 years old (n = 826), and 5 years old (n = 770). Structural equation modeling (SEM) was employed to test our hypotheses. Results There was a significant sex difference in the prediction of ODD symptoms due to the opposite directionality in which increasing vagal reactivity was associated with an increase in ODD symptoms in girls and a reduction of ODD symptoms in boys. This Sex by Vagal reactivity interaction was common for both ODD dimensions, with no sex by dimension-specific associations. Conclusions Physiological reactivity to a stressful situation predicts differently ODD symptoms in boys and girls very early in life, with no difference across irritability and headstrong components. Findings are discussed in the context of the several mechanisms involved on the later development of distinct psychiatric disorders in boys and girls.
