Addictology Expert Patients' Fields of Intervention

Although there are many publications concerning the benefit of the interventions of the self-help movements and peer health mediators in psychiatry, no studies have described the intervention specific to patients with expertise in addictology (EP), nor evaluated their effectiveness. The objective of this study is twofold: identify and define the fields of intervention of EPs adapted to the specific needs of addictology patients. And validate, through a pilot study, the intermediate effectiveness of EP intervention. This EP intervention will be built on the areas of expertise defined in the first step. Intermediate effectiveness will be measured by patients' ability to manage their addiction. The first part of the study will consist of a preliminary qualitative patient-centered study to clarify patients' needs and expectations regarding the content of the EPs' intervention into a one addictology service of the university hospital of Bichat, Paris, France. This will make it possible to translate these needs into fields of expertise to address during the EPs' intervention and will result in the creation of a hetero-questionnaire. The second part of the study will consist of a before-and-after comparative study on inpatients who are their own controls based on the hetero-questionnaire constructed through the qualitative study. This study will identify the main EP's intervention fields in addictology in which EP are more relevant to patients. Thus, their inpatient interventions can be validated and improved, and better carried by addiction professionals.
