Exposure to actual or threatened death, serious injury or sexual violation either directly, as a witness, learning of violence to a loved one or through repeated exposure to details of trauma. Sexual violation is a new part of the definition. Media exposure does not qualify as traumatic stress. Secondary exposure is limited to learning about violence to a loved one and repeated, extreme exposure (e. g. first responders collecting human remains) Support and resilience help prevent or reduce ptsd. First responders/emergency workers are less than half as likely to develop. Protected by training, preparation and sense of purpose. Hardiness, sense of commitment, control and challenge in facing stress, predict lower risk for ptsd. High comorbidity with depression, anxiety disorders and substance abuse. Others include disturbing nightmares, physical symptoms, grief, and relationship difficulties. 33% of rape survivors had suicidal thoughts, 13% attempted suicide.
