Situational Action Theory (SAT), a recently developed explanation of criminal conduct, is becoming increasingly studied. Hitherto, however, nearly all tests of the theory and its hypotheses have been based on samples of adolescents or young adults. Studies drawing on the older population have been missing so far. This work addresses the interplay of moral beliefs and the ability to exercise self-control in crime causation among respondents aged 50 years and over. In line with SAT and the results obtained previously for young people, our analyses show that self-control ability affects offending among older adults too, particularly when personal morality is weak.
