We also tested whether the relationship between cortisol reactivity and children's internalizing and externalizing problems varied as a function of their developmental history of stressful experiences and relationships. Method Participants included 400 children (M = 9.99 years, SD = 0.74 years) from the Children's Experiences and Development Study. Early risk exposure was measured by children's experiences of harsh, nonresponsive parenting at 3 years. Recent risk exposure was measured by children's exposure to traumatic events in the past year. Children's cortisol reactivity was measured in response to a social provocation task and parents and teachers described children's internalizing and externalizing problems. Results The effect of recent exposure to traumatic events was partially dependent upon a child's early experiences of harsh, nonresponsive parenting: the more traumatic events children had recently experienced, the greater their cortisol reactivity if they had experienced lower (but not higher) levels of harsh, nonresponsive parenting at age 3. The lowest levels of cortisol reactivity were observed among children who had experienced the most traumatic events in the past year and higher (vs. lower) levels of harsh, nonresponsive parenting in early childhood. Among youth who experienced harsh, nonresponsive parent–child relationships in early childhood and later traumatic events, lower levels of cortisol reactivity were associated with higher levels of internalizing and externalizing problems. Conclusions Hypothalamic–pituitary–adrenal (HPA) axis reactivity to psychological stressors and the relationship between HPA axis reactivity and children's internalizing and externalizing problems vary as a function of a child's developmental history of exposure to stressful relationships and experiences.

Take your mind off it: Coping style, serotonin transporter linked polymorphic region genotype (5-HTTLPR), and children's internalizing and externalizing problems / Jessie I. CLINE in Development and Psychopathology, 27-4 (Part 1) (November 2015)

JAFFEE, Auteur Année de publication : 2015 Article en page(s) : p.1129-1143 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Individuals with the short variant of the serotonin transporter linked polymorphic region gene are more susceptible than individuals homozygous for the long allele to the effects of stressful life events on risk for internalizing and externalizing problems. We tested whether individual differences in coping style explained this increased risk for problem behavior among youth who were at both genetic and environmental risk. Participants included 279 children, ages 8–11, from the Children's Experiences and Development Study. Caregivers and teachers reported on children's internalizing and externalizing symptoms, and caregivers and children on children's exposure to harsh parenting and parental warmth in middle childhood, and traumatic events. Children reported how frequently they used various coping strategies. Results revealed that short/short homozygotes had higher levels of internalizing problems compared with long allele carriers and that short allele carriers had higher levels of externalizing problems compared with long/long homozygotes under conditions of high cumulative risk. Moreover, among children who were homozygous for the short allele, those who had more cumulative risk indicators less frequently used distraction coping strategies, which partly explained why they had higher levels of internalizing problems. Coping strategies did not significantly mediate Gene × Environment effects on externalizing symptoms.

Variation in community intervention programmes and consequences for children and families: the example of Sure Start Local Programmes / Edward MELHUISH in Journal of Child Psychology and Psychiatry, 48-6 (June 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-6 (June 2007) . - p.543–551 Titre : Variation in community intervention programmes and consequences for children and families: the example of Sure Start Local Programmes Type de document : Texte imprimé et/ou numérique Auteurs : Edward MELHUISH, Auteur ; Jay BELSKY, Auteur ; Angela ANNING, Auteur ; Mog BALL, Auteur ; Jacqueline BARNES, Auteur ; Helena ROMANIUK, Auteur ; Alastair LEYLAND, Auteur ; NESS RESEARCH TEAM, Auteur Année de publication : 2007 Article en page(s) : p.543–551 Langues : Anglais (eng) Mots-clés : Child-development parenting community-interventions programme-implementation programme-effectiveness Sure-Start Index. décimale : PER Périodiques Résumé : An area-based initiative, Sure Start Local Programmes (SSLPs), was established by the UK government to reduce social exclusion through improving the well-being of children aged 0–3 years and their families in disadvantaged communities; a true community intervention in that all children under four and their families in specified areas served as targets of universal services. A national evaluation examined the links between variation in programme implementation and effectiveness. Methods: Data gathered from multiple sources produced measures of implementation in terms of proficiency, services and staffing. Measures of programme impact on child/parenting outcomes derived from multilevel models, controlling for child, family and area characteristics, were identified to demonstrate programme effectiveness. Results: Some modest linkage between programme implementation (e.g., proficiency, empowerment of parents and staff, identification of users) and effectiveness for child and parenting outcomes. Conclusions: Overall proficiency and specific aspects of implementation may influence effectiveness, which should guide the design of other child, family and community services.
