Based on Situational Action Theory (SAT) the overall aim is to study the interaction between individual factors (morality and ability to exercise self-control) and the moral of settings in which they interact. Furthermore, to examine similarities and differences between male and female adolescents. Data is derived from the longitudinal project Malmö Individual and Neighbourhood Development Study (MINDS). Approximately 500 adolescents from a cohort of children born 1995, residing in Malmö year 2007, have been studied. Three waves of data are used, from when the adolescents were between 15-19 years of age, rendering a sample of almost 400 adolescents. The longitudinal interactions are tested via structural equation models, and the results discussed against theoretical implications as well as implications regarding criminal behaviour.
