The paper begins by discussing different types of crime prevention strategies and then proposes an integrated theory of crime. An integrated crime prevention program is presented, problems associated with program implementation and evaluation are considered, and key issues that need to be addressed in developing integrated crime prevention strategies are identified. The author concludes that developmental and situational crime prevention theories and strategies are not incompatible, that more research is needed to develop offender and offense typologies, and that a key issue in developing an integrated crime prevention program involves the extent to which crime prevention strategies should be based on theoretical constructs versus empirically derived risk and protective factors. He derives five major crime prevention strategies from integrated theory: (1) decrease long-term criminal potential; (2) decrease short-term criminal potential; (3) decrease criminal opportunities; (4) change decisionmaking in criminal opportunities; and (5) make consequences of crime less reinforcing. 74 references and 2 figures
