Two major themes in the delinquency literature are the roles of family structure and childhood victimization. Combining these two lines of research, the current project examines the unique contribution of family structure and victimization on the serious delinquency of a nationally representative sample of adolescents. In addition, the authors examine whether the form of families serves to condition the relationship between victimization and delinquency. Past research indicates that abuse is more likely to occur in two-parent families of a "mixed" form, specifically in the presence of a live-in boyfriend or stepfather. However, little is known regarding the impact of victimization on delinquency across different types of family structure. Guided by a theoretical framework acknowledging that notions of justice influence the experience of victimization, our analyses indicate that, although victimization is more likely to occur in nonintact two-parent families, victimization is more likely to result in serious delinquency in intact families and single-parent families.
