 OVERALL AIM AND RESEARCH QUESTIONS The overall aim of this project is to adapt the DBI to be implementable on a large scale by means of interactive groups working online, and new methods for easily and effectively training program facilitators, with recruitment using the model of social media e.g., through various websites, collaborative projects, and blogs that are popular among the youth, and to evaluate the effect of the adapted version of the DBI. The program will remain interactive, and its effect can most probably be maintained over time to a higher degree than when implemented in its original format, as booster sessions can easily be included with no major problems in terms of logistics, meetings, allocation of participants, etc. The new format will also provide a framework for recruitment which reduces the risk of stigmatization.
