This report describes the process that allowed the implementation of Multisystemic Therapy (MST) in Chile. The case can be considered as innovative, due the little experience in the country about the implementation of high quality, evidence-based programs for crime prevention. The description of the process from the perspective of the author may provide useful information for policy makers interested in implementing evidence-based crime prevention practices.
