Behavioral genetics studies have reached the conclusion that a significant portion of variance in antisocial and violent behavior is due to both genetic and non-shared environmental factors, but methodology used in these studies are ill equipped for empirically exploring the specific nonshared environmental differences that account for why identical twins and other sibling pairs differ in their behavioral outcomes and how they may influence one another. Using data from Waves I and II of the National Longitudinal Study of Adolescent Health, the current study estimates longitudinal, multilevel Actor Partner Interdependence Models to investigate how several domains of nonshared environmental risk factors explain why identical twins differ in their antisocial and violent behaviors while taking into account their shared environments and characteristics. Further, this study investigates whether members of twin pairs influence each other’s behavior over time. Implications of our results for biosocial criminology, and methodological approaches to understanding nonshared environmental effects specifically, are discussed.Reference Type
