Creating concrete operational indicators for narrative depictions of complex concepts, identifying and recruiting appropriate samples, and identifying designs permitting informed causal judgments in a largely nonexperimental field are among the most challenging intellectual achievements in the behavioral sciences. This chapter discusses misuses of self-control theory in research on crime and delinquency. It presents a critical evaluation of the “sole cause” and “spuriousness thesis” in depictions of self-control theory. Multiple factor and risk factor approaches as alternatives to general theories are discussed. In addition, the chapter examines how a choice theory integrates demographic factors and crime and the idea of family variables as a structural approach to crime theory. The integration of individual differences and sociological theory is also discussed.
