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 ...
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 ...
Contagion of anxiety symptoms among adolescent siblings : a twin study
This study examined whether social contagion of anxiety symptoms is present between siblings during early adolescence and whether this process is moderated by sex, relationship quality, and zygosity. Based on 634 monozygotic ...
Complex effects of dyslexia risk factors account for ADHD-traits : evidence from two independent samples
Background: Developmental dyslexia (DD) and attention deficit/hyperactivity disorder (ADHD) are among the most common neurodevelopmental disorders, whose etiology involves multiple risk factors. DD and ADHD co-occur in the ...
Early warm-rewarding parenting moderates the genetic contributions to callous-unemotional traits in childhood
Warm-rewarding genetic callous-unemotional
Background Previous gene–environment interaction studies of CU traits have relied on the candidate gene approach, which does not account for the entire genetic load of complex phenotypes. Moreover, these studies have ...
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 ...
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 ...
The gene–environmental architecture of the development of adolescent substance use
Gene–environmental architecture of adolescent substance use
(Cambridge University Press, 2018-02-19)
Background: Using a longitudinal twin design and a latent growth curve/autoregressive approach, this study examined the genetic-environmental architecture of substance use across adolescence. Methods: Self-reports of ...
Persistence and innovation effects in genetic and environmental factors in negative emotionality during infancy : a twin study
(Public Library of Science, 2017-04-27)
Background Difficult temperament in infancy is a risk factor for forms of later internalizing and externalizing psychopathology, including depression and anxiety. A better understanding of the roots of difficult temperament ...
