A strategic action plan 2010-2014 to improve the health of persons “under judicial watch” was created jointly by the ministries of health and justice. The plan highlighted actions oriented toward health promotion as established by the the UN’s Ottawa charter of 1986. As part of this plan, the DPJJ (directorate for youth judicial protection) seeks to reduce the consumption of psychoactive products by minors under court protection involved or not in trafficking and dealing, through health promotion tools. The approach is to create an auto-evaluation questionnaire using EpiConcept's Voozanoo platform which can be used by the individual to improve prevention, quitting and case handling. The collected data will also be used to improve general knowledge on the state of health of these minors and to identify their needs and the corresponding actions for the DPJJ.
