This study examined (a) whether, in line with a gene-environment correlation (rGE), a genetic disposition for anxiety puts children at risk of having anxious friends or having no reciprocal friends; (b) to what extent these ...
The dark side of friends : a genetically informed study of victimization within early adolescents’ friendships
(Taylor & Francis, 2015)
Using a genetically informed twin design, this study examined (a) whether, in line with gene–environment correlation (rGE), a genetic disposition for anxiety puts children at risk of being victimized by a close friend or ...

Longitudinal links between gambling participation and academic performance in youth : a test of four models
Gambling participation and academic achievement
Gambling participation and low academic performance are related during adolescence, but the causal mechanisms underlying this link are unclear. It is possible that gambling participation impairs academic performance. ...
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 ...
