L’analyse lexicale au service de l’évaluation d’un dispositif d’accompagnement socio-sanitaire à destination de personnes vivant avec une schizophrénie

International audience; Objective: Through the study of a social and health care program supporting the recovery of people living with schizophrenia (PASSVers), this article aims to show the interest of using the Alceste lexical analysis method to evaluate health-promoting activities. Method: Semi-structured interviews were conducted with users supported for 12 to 20 months (n = 21), nurses and social workers (n = 11), and family caregivers (n = 6). The corpus was analyzed using Alceste software. Results: Each population used a specific vocabulary to evaluate the program, reflecting different viewpoints towards it. The contextualization of the vocabulary significantly present in the discourse classes highlighted the program's effects on each of the three groups. We noticed a shift in posture among professionals with a detachment from purely medical concerns, as well as the impact of the support on the health of the users and on the well-being of their relatives. Discussion: Lexical analysis appeared particularly relevant for evaluating a health promotion program such as PASSVers. Indeed, this tool for interpreting a corpus is based on the distribution of vocabulary, excluding any judgment by the analyst. Thus, this method ensures a rigorous methodological basis for determining the classes of discourse to be interpreted. Conclusion: The Alceste method enables the rigorous study of a corpus through a detailed analysis of the vocabulary. In the evaluation of the PASSVers program, it allowed us to highlight the specific points of view of each group, and to identify the benefits of the program for each of them.
