[Psychological consequences of the 1994 massacres in Rwanda]

A research program on the prevalence of reactions of posttraumatic stress is described in this article. The program is specifically centered on the psychological consequences of the April 1994 events in Rwanda and the genocide that followed. It includes three psycho-epidemiologic studies: 1) a study of non-accompanied Rwandan children; 2) a study of a small group of belgian cooperants; and 3) a study of an important sample of belgian civilians and militaries having been through the rwandan events. The psychological impact of the rwandan events is described in terms of prevalence of symptoms of posttraumatic stress.
