How Prevalent Are Toxic Events and Event-Attributed Clinical Distress Disorders?

If PTSD is to have any meaning as a specific disorder caused by bad experiences, it requires the assumption that toxic events are relatively rare, because most people do not show or report PTSD. To evaluate this background assumption, it is necessary to examine the prevalence rates for toxic events and then to see how these compare to the prevalence rates for event-attributed distress disorders. If toxic events have a powerful role in determining distress disorders, then we should expect rather similar low lifetime prevalence rates for both.
