Data were obtained from the Environmental Risk (E-Risk) Longitudinal Twin Study, an epidemiological study of 2,232 children (1,116 twin pairs) followed to 18 years of age (with 93% retention). To assess adolescent victimization, we combined best practices in survey research on victimization with optimal approaches to measuring life stress and traumatic experiences, and introduce a reliable system for coding severity of victimization. One in three children experienced at least one type of severe victimization during adolescence (crime victimization, peer/sibling victimization, Internet/mobile phone victimization, sexual victimization, family violence, maltreatment, or neglect), and most types of victimization were more prevalent among children from low socioeconomic backgrounds. Exposure to multiple victimization types was common, as was revictimization; over half of those physically maltreated in childhood were also exposed to severe physical violence in adolescence. Biometric twin analyses revealed that environmental factors had the greatest influence on most types of victimization, while severe physical maltreatment from caregivers during adolescence was predominantly influenced by heritable factors. The findings from this study showcase how distinct levels of victimization measurement can be harmonized in large-scale studies of health and development.

Why some children with externalising problems develop internalising symptoms: testing two pathways in a genetically sensitive cohort study / Jasmin WERTZ in Journal of Child Psychology and Psychiatry, 56-7 (July 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-7 (July 2015) . - p.738-746 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.
