Titre : Early classroom reading gains moderate shared environmental influences on reading comprehension in adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Jeanette TAYLOR, Auteur ; Florina ERBELI, Auteur ; Sara A. HART, Auteur ; Wendy JOHNSON, Auteur Article en page(s) : p.689-698 Langues : Anglais (eng) Mots-clés : Reading comprehension environmental moderation genetic influence Index. décimale : PER Périodiques Résumé : BACKGROUND: Reading is important for children's success in school and beyond, yet many adolescents fail to reach expected levels of proficiency. This highlights the need to better understand the factors that influence reading effectiveness over time, including genes and environment. Greater expression of genetic influence on first- and second-grade reading fluency has been observed in higher quality classroom reading environments. To what degree this early environment continues to influence genetic and other environmental influences on later reading is unknown and was tested in this study. METHODS: The quality of the early classroom reading environment was approximated by gains in oral reading fluency (ORF) across the school year among first- or second-grade classmates of 546 MZ and 1,016 DZ twin children (mean age = 7.13 years; SD = 0.45) who had reading comprehension scores from a state-wide mandatory test in school year 2013-2014 when most twin pairs were in seventh to tenth grade (mean age = 14.41; SD = 1.13) in a variable called Class ORF Gain. Biometrical models were fit to the data to assess whether Class ORF Gain moderated the genetic, shared environmental and/or nonshared environmental variance associated with adolescent reading comprehension. RESULTS: Class ORF Gain moderated shared environmental influences on reading comprehension 6-9 years later. When early classroom reading gains were poor, variability in reading comprehension in adolescence was high and was associated largely with shared environmental influences. When early classroom reading gains were good, overall and shared environmentally influenced variability in adolescent reading comprehension was lower so that genetic influences were most relevant in explaining that variability. CONCLUSIONS: Our findings suggested that classroom reading environment experienced when children were learning to read had a lasting influence on the factors underlying variability in later reading effectiveness.

Titre : Why some children with externalising problems develop internalising symptoms: testing two pathways in a genetically sensitive cohort study Type de document : Texte imprimé et/ou numérique Auteurs : Jasmin WERTZ, Auteur ; Helena ZAVOS, Auteur ; Timothy MATTHEWS, Auteur ; Kirsten HARVEY, Auteur ; Alice HUNT, Auteur ; Carmine M. PARIANTE, Auteur ; Louise ARSENEAULT, Auteur Article en page(s) : p.738-746 Langues : Anglais (eng) Mots-clés : Externalising and internalising problems failure model genetic influence development Index. décimale : PER Périodiques Résumé : Background Children with externalising problems are at risk of developing internalising problems as they grow older. The pathways underlying this developmental association remain to be elucidated. We tested two processes that could explain why some children with externalising problems develop internalising symptoms in preadolescence: a mediation model whereby the association between early externalising and later new internalising symptoms is explained by negative experiences; and a genetic model, whereby genes influence both problems. Methods We used data from the Environmental Risk (E-Risk) Study, a 1994–1995 birth cohort of 2,232 twins born in England and Wales. We assessed externalising and internalising problems using combined mothers’ and teachers’ ratings at age 5 and 12. We measured bullying victimisation, maternal dissatisfaction and academic difficulties between age 7 and 10 and used linear regression analyses to test the effects of these negative experiences on the association between early externalising and later internalising problems. We employed a Cholesky decomposition to examine the genetic influences on the association. Results Children with externalising problems at age 5 showed increased rates of new internalising problems at age 12 (r = .24, p < .001). Negative experiences accounted for some of the association between early externalising and later internalising problems. Behavioural-genetic analyses indicated that genes influencing early externalising problems also affected later internalising problems. Conclusions Our findings highlight the role of genetic influences in explaining why some children with externalising problems develop internalising symptoms in preadolescence. Negative experiences also contribute to the association, possibly through gene–environment interplay. Mental health professionals should monitor the development of internalising symptoms in young children with externalising problems.
