Gottfredson and Hirschi's general theory of crime has received considerable empirical support. Researchers have found that low self-control, the general theory's core concept, is related to lawbreaking and to deviant behavior considered "analogous" to crime. This article extends the research by assessing the effects of low self-control on crime and analogous behaviors and by using two distinct measures of self-control, an attitudinal measure and the analogous/behavior scale. The article also examines the claim that low self-control has effects not only on crime but also on life chances, life quality and other social consequences. Consistent with the general theory, the article finds that both measures of self-control have effects on crime, even when controlling for a range of social factors. Analysis also reveals general support for the theory's prediction of negative relationships between low self-control and social consequences other than crime--life outcomes and quality of life.
