For example, in the St. […]

Prevalence of Posttraumatic Stress Disorder(PTSD)

Prevalence of Posttraumatic Stress Disorder(PTSD) Epidemiologic studies conducted over the past two decades provided empirical information about the prevalence of PTSD in the general population and among individuals who have been exposed to specific types of potentially traumatic events. This research indicates that most individuals who are exposed to a potential trauma do not develop […]
