Vilavi uses recognized approaches led by qualified staff benefiting from continuous training. These approaches include the cognitive-behavioral approach , relapse prevention , the therapeutic community  and motivational interviewing . These interventions have as a common basis the search for and the maintenance of a « therapeutic alliance », that is to say a relationship of partnership between the user and the counselor, grounded on humanistic principles and dedicated to the accomplishment of the personal project.
