Situational Action Theory (SAT) is an important theoretical development with relatively broad empirical content, reflected in highly specific hypotheses about crime causation. It offers an alternative concept of self-control to that of the General Theory of Crime and predicts that the effect of self-control on crime depends on crime contemplation. Crime contemplation is the tendency to consider crime as an action alternative. This paper is a test of SAT using data on 1304 juveniles from four Latin American cities with relatively high crime rates and impunity levels. It therefore contributes to cross-national testing. Both ordinary least squares and negative binomial regression techniques are applied. Three different ways to test interactions in non-linear models are used. Findings support the hypothesis. Results and limitations are discussed.
