Within the Situational Action Theory (SAT), exposure to criminogenic settings is one of the core aspects in the explanation of young people’s crime involvement. To decrease exposure to crime-inducing settings we need to increase knowledge of the determinants of exposure to these kinds of settings. The present study aims at examining the importance of how changes in two monitoring-related measures: parental knowledge and time spent with family relate to changes in what can be considered as crime-inducing settings: involvement with deviant peers and time spent with peers in unsupervised and unstructured activities. The sample is drawn from MINDS, and constitutes data on the 482 young persons who participated in both the second and third wave of data collection (age 15-17). The data concern in-depth data detailing individual characteristics as well as family and peer related variables. Young person’s exposure to different settings was collected using two research instruments, a survey and a Space-Time Budget (STB). The STB provide data on the participants exposure to different settings by measuring which settings they take part of and what activities they engage in, from which we gain information on their activity fields. Negative binomial multilevel analyses were carried out in order to examine both between- and within-person effects. The findings indicate that monitoring has an overall negative effect of on time spent in criminogenic settings. However, examining individual change over time shows that changes in parental knowledge is associated to change in involvement with deviant peers but not in time spent unsupervised in unstructured activities. Changes in time spent with family is associated to changes in time spent unsupervised in unstructured activities but not to changes in involvement with deviant peers.
