Associations between mother-child relationship quality and adolescent adjustment : using a genetically controlled design to determine the direction and magnitude of effects
This study used a genetically controlled design to examine the direction and the magnitude of effects in the over-time associations between perceived relationship quality with mothers and adolescent maladjustment (i.e., ...
Links between friends' physical aggression and adolescents' physical aggression : what happens if gene-environment correlations are controlled?
Exposure to deviant friends has been found to be a powerful source of influence on children’s and adolescents’ aggressive behavior. However, the contribution of deviant friends may have been overestimated because of a ...
Links between the mother-adolescent and father-adolescent relationships and adolescent depression : a genetically informed study
Links between the parent-adolescent Relationship quality and depression
(Taylor & Francis, 2017-08-18)
This study examined the unique roles of support and conflict in the relationship with the mother and the father in predicting changes in adolescents’ depressive symptoms over a 1- year period. Potential moderating effects ...
Genetic and environmental influences on height from infancy to early adulthood : an individualbased pooled analysis of 45 twin cohorts
(Nature Publishing Group, 2016-06-23)
Height variation is known to be determined by both genetic and environmental factors, but a systematic description of how their influences differ by sex, age and global regions is lacking. We conducted an individual-based ...
Peer victimization and anxiety in genetically vulnerable youth : the protective roles of teachers' self-efficacy and anti-bullying classroom rules
Many victimized youngsters are at risk of developing internalizing problems, and this risk seems to be especially pronounced when they are genetically vulnerable for these problems. It is unclear, however, whether protective ...
Gene-environment correlation linking aggression and peer victimization : do classroom behavioral norms matter?
Using a genetically informed design based on 197 Monozygotic and Dizygotic twin pairs assessed in grade 4, this study examined 1) whether, in line with a gene-environment correlation (rGE), a genetic disposition for physical ...
Heterogeneity in the development of proactive and reactive aggression in childhood : Common and specific genetic-environmental factors
(Public Library of Science, 2017-12-06)
Background Few studies are grounded in a developmental framework to study proactive and reactive aggression. Furthermore, although distinctive correlates, predictors and outcomes have been highlighted, proactive and ...
Phenotypic and genetic associations between reading comprehension, decoding skills, and ADHD dimensions : evidence from two population-based studies
Phenotypic and genetic associations between reading and ADHD
BACKGROUND: The phenotypic and genetic associations between decoding skills and ADHD dimensions have been documented but less is known about the association with reading comprehension. The aim of the study is to document ...
The expression of genetic risk for aggressive and non-aggressive antisocial behavior is moderated by peer group
Numerous studies have shown that aggressive and non-aggressive antisocial behaviors are important precursors of later adjustment problems. There is also strong empirical evidence that both types of antisocial behavior are ...
The genetic and environmental etiology of the association between vocabulary and syntax in first grade
Etiology of vocabulary and syntax
(Taylor & Francis, 2018-03-09)
This study examined the genetic and environmental etiology of vocabulary, syntax, and their association in first graders. French-speaking same-sex twins (N = 555) completed two vocabulary tests, and two scores of syntax ...
