This is a hybrid efficacy-implementation Type I recovery based interventional study based on a multicenter follow-up of a cohort of 300 patients with severe and persistent mental disorders (60 patients per center). The evolution of concepts and means of evaluation now allow a precise description of the mechanisms of recovery in all the diversity of its expression among patients, their entourages and the psychiatric facilities.~In the present study, the investigators aim to characterize simultaneously the patients' trajectories and the evolution of the care facilities and their professionals with respect to the principles of recovery. This double exploration should allow to build theoretical and practical references for the extension of this approach to other centers in France.~The study considers a dual timeline for data collection:~The timeline associated with patients defined by the inclusion of each patient and extending to 24 months after, punctuated by an assessment at 12 months;~The timeline of the inclusion centers and professionals involved in the rehabilitation projects defined by the beginning of the study and extending beyond the end of inclusion of the last patient, punctuated by annual intermediate evaluations of the means allocated by the structure and the positioning of the personnel in terms of recovery.~The intervention consists in a follow-up of the patients and their relatives by a psychiatric nurse and a social worker during 12 months. Both professionals, trained to rehabilitation and recovery principles, will focus on the patient's needs and goals in order to improve the outcome, quality-of-life and clinical status.
Prospective longitudinal uncontrolled multicenter study, with cohort follow-up, focusing on patients, professionals, relatives and structures evolution during the implementation of recovery based intervention.
