Impact of a Brief Motivational Intervention Including Counter-marketing Arguments With a Population of Patients With Moderate to Severe Alcohol Use Disorders Who Are Followed up on an Outpatient Basis (Primary Care or Addictology) (DEPREV_Phase 3)

Alcohol consumption is the second cause of avoidable death after tobacco. The Evin law was constructed in 1991 with the aim of reducing exposure to alcohol marketing among the youngest. But this law is currently extremely weakened, and in a press release of February 26, 2018, the French Alcohol Society is alarmed by these developments. Studies on the impact of alcohol marketing focus for the most part on young adolescents and the links between marketing exposure and alcohol initiation. But beyond these links, little work has been done on the impact of alcohol marketing on vulnerable subjects with regular alcohol consumption. Alcohol consumption is one of the very first causes of hospitalization in France. The damage is often limited to the notion of risks of dependence, but it can appear as soon as consumption of 1 standard unit/day and mainly concerns the 45-64 year olds. To our knowledge, there are no studies on the impact of alcohol marketing carried out among regular alcohol users with moderate or severe alcohol use disorders. This population is, however, the target of manufacturers, since 10% of the French population consumes 58% of the alcohol sold in France. Moreover, although in the context of tobacco, counter-marketing campaigns and strategies are used to help users develop resistance to the positive marketing stimuli of alcohol, there are no studies that have evaluated this type of intervention with patients with moderate to severe alcohol use disorders. The DEPREV\_phase 3 study is a prospective, controlled, randomised, open-label study. Patients followed in the primary care network participating in the study and those followed in the addictology network of northern Finistère in the context of their pathology will be offered the opportunity to participate in the study. Patients agreeing to participate will be randomized in 2 groups (1:1) by the addictology unit: * Control group: routine routine follow-up (follow-up in consultations with the attending physician or addictologist) + assessments at Month 1, Month 3 and Month 6. * Intervention group: Routine routine follow-up (follow-up in consultation with the attending physician or addictologist) + assessments at Month 1, Month 3 and Month 6 + motivational interview (2 individual sessions, during the first month after inclusion). Patients will then be followed up and evaluated at 1, 3 and 6 months after the inclusion visit.
