Abstract
This study investigated gene-environment correlations and interactions underlying the association between distinct developmental trajectories of adolescents' antisocial behavior and their friends' antisociality. Participants were 398 twin pairs (53% girls; 87% European descent) followed from age 13 to 19 years. Self-reported antisocial behavior was obtained from the twins and from their friends. Latent class growth modeling identified three antisocial behavior trajectories: nonantisocial, stable-low, and persistent-high. Biometric modeling revealed significant genetic influence on the probabilities of following either the nonantisocial or the persistent-high antisocial behavior trajectory. In contrast, the probability of following the stable-low trajectory was almost entirely explained by environmental influences. All three trajectories were correlated with friends' antisociality and these correlations were entirely explained by shared underlying environmental-not genetic-pathways. Moreover, friends' antisociality moderated the relative influence of genetic factors on the probability of following the persistent-high trajectory, as well as the relative influence of environmental factors on the probability of following the stable-low trajectory. The discussion stresses the importance of distinguishing distinct developmental trajectories of antisocial behavior during adolescence and the differential moderating role played by friends' antisociality.

期刊介绍：
Developmental Psychology ® publishes articles that significantly advance knowledge and theory about development across the life span. The journal focuses on seminal empirical contributions. The journal occasionally publishes exceptionally strong scholarly reviews and theoretical or methodological articles. Studies of any aspect of psychological development are appropriate, as are studies of the biological, social, and cultural factors that affect development. The journal welcomes not only laboratory-based experimental studies but studies employing other rigorous methodologies, such as ethnographies, field research, and secondary analyses of large data sets. We especially seek submissions in new areas of inquiry and submissions that will address contradictory findings or controversies in the field as well as the generalizability of extant findings in new populations. Although most articles in this journal address human development, studies of other species are appropriate if they have important implications for human development. Submissions can consist of single manuscripts, proposed sections, or short reports.
