Severe and persistent mental health disorders are associated with impairments in cognitive, emotional, and social functioning. Some of these disorders involve cognitive challenges that are likely to negatively affect quality of life. In this context, the early identification of cognitive difficulties and intervention through cognitive remediation become priority therapeutic targets to facilitate individual rehabilitation. From this perspective, the present study aims to determine the relevance of a personalized cognitive remediation program developed by neuropsychologists at Pierre-Janet Hospital, called RECAMEX, to guide its sustainable adoption and to support its implementation in other clinical settings.
