[New strategies for prevention in adolescents and young adults]

For various reasons, it is justified to revise the classical strategies of intervention concerning medical and social action to help young people. New behaviours such as drug addiction, for instance, have emphasized the inadequacies of the conventional means of treatment. Since 1970, Youth Advisory Services have appeared in Europe. Their aims may be various: information, counselling, lodging, social and educative help, medical assistance. These services which were created by the community have such ethical and organizational features that it is easy to discern them among the conventional administrative services. Their users are mainly teenagers and young adults whose reasons for consultation are due to various causes. The originality of the methods, facilities and principles of these innovating services may be considered as a decisive contribution to the research of new prevention strategies to help young people.
