It begins by discussing various types of crime prevention strategies and then proposes an integrated theory of crime, followed by a discussion of key theoretical issues that arise in this theory. The integrated theory presented encompasses both long-term influences on criminal potential and decisionmaking in criminal opportunities. In addition, the theory suggests that it is desirable also to study influences on short-term, within- individual variations in criminal potential, especially the causes of short-term variations in states such as boredom, anger, and frustration, as well as the feedback effects of the consequences of crime on long-term criminal potential and on decisionmaking in criminal opportunities. The author proposes an integrated prevention program, followed by consideration of problems that arise in implementation and evaluation. Throughout this paper, the aim is to identify key issues that must be addressed in the development of integrated crime prevention strategies; the author concludes that every country should have an integrated crime prevention program. 74 references
