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
