Families are a key element in helping children develop into properly functioning members of society. The relationships that individuals have with the members of their family will greatly influence them throughout their lives. Past work highlights the roles families, and siblings in particular play in the development of antisocial behavior, but it is also important to consider the ways in which the intensification of antisocial behavior (i.e., the initiation of substance use) in adolescence changes and alters trajectories of siblings’ relationships with one another. Thus, in the current study we are examining the longitudinal links between antisocial behavior and adolescents’ sibling relationships. Data for our study come from the Flourishing Families Project, a seven phase longitudinal study of 700 families. Both parents and adolescents reported on the adolescent’s antisocial behavior and adolescents’ reported on their relationship with their closest aged sibling. We are using SAS to conduct growth curve models of sibling relationships over time as moderated by patterns of antisocial behavior. Preliminary analysis suggests that in many cases antisocial behavior is linked to less sibling warmth (r = -.11, p < .01) and greater sibling conflict (r = .22, p < .001). In conclusion we anticipate that our analysis will support the notion of the complexity of family life and that the choices and behavior of an individual family member may have implications for the development of family relationships.
