Suicide prevention is a major public health issue addressed by the French national VigilanS program, which focuses on maintaining contact after a suicide attempt. However, some groups, particularly individuals with post-traumatic stress disorder (PTSD), appear less receptive to this approach. Although still underrecognized in prevention strategies, PTSD is strongly associated with repeated suicide attempts. This article examines how PTSD may interact with VigilanS follow-up procedures and proposes enriching reflection through experiential knowledge by involving patient partners who have experienced both a suicide attempt and PTSD. Such an approach, still rarely used, may offer a promising way to better adapt interventions to the needs of those concerned.
