In a recent critique and elaboration of general strain theory, Agnew (2001) argued that criminal victimization might be among the most consequential strains experienced by adolescents, and therefore might be an important cause of delinquency. Few studies to date, however, had examined victimization as a potential cause-rather than outcome-of delinquency. This article addresses this void by examining predictions from general strain theory about the effects of victimization on later involvement in delinquency. The analyses indicated that violent victimization significantly predicted later involvement in delinquency, even when controlling for the individual's earlier involvement in delinquency. Moreover, general strain theory appears to be a useful theoretical framework for examining this relationship. The effects of victimization on delinquency were explained in part by its effects on anger (the key intervening variable specified by the theory). Partial support also emerged for the theory's hypothesis that the effects of strain should be conditional upon other factors. Specifically, the effects of victimization were marginally greater for juveniles with weak emotional attachment to their parents and significantly greater for those low in self-control.
