Impact of Mental Health First Aid-trained Peers on the Mental Well-being of First-year Medical Residents.

Medical students, especially those in postgraduate training, face a complex array of challenges such as fatigue; work-life balance conflicts; difficulties managing dual hierarchies (hospital and university). Surprisingly, residents receive little to no dedicated training in recognizing and managing psychiatric disorders, except for psychiatry residents. This gap is exacerbated by persistent stigma towards psychiatric conditions. The Mental Health First Aid (MHFA) training approach could offer an innovative solution, addressing the root of the problem. This prospective, single-center cohort study aims to compare (1) the mental well-being of first-year specialty residents in the Lyon subdivision exposed to MHFA-trained peers; with (2) the mental well-being of unexposed second-year specialty residents. The hypothesis is that exposure to peers trained in MHFA improves well-being and reduces symptoms of burnout, depression, and anxiety at 3, 6, 9, and 12 months among peer residents.
