Answer to Question 1
Unfortunately for some, the reaction to traumatic stressors may result in the development of a post-traumatic stress disorder (PTSD). PTSD is characterized by a number of symptoms including persistently re-experiencing the traumatic event, avoiding stimuli correlated with the traumatic event, experiencing a general response numbing, and having persistent increased arousal. The duration of the overall symptom pattern lasts at least a month, and there is distress or impairment in one or more primary areas of functioning.
Answer to Question 2
Traumatic stressors are events such as combat, natural or human-made disasters, violent assault, sexual assault, kidnapping, torture, serious or life- threatening accidents, a life-threatening diagnosis, a close friend or relative dying suddenly and unexpectedly, being held captive perhaps as a POW or in a concentration camp, or other highly distressing experiences that can result in feelings of terror, extreme fright, or helplessness. As is the case with all stressors, a person's reaction to severe stressors is individualistic and subjective, in part, because each person appraises the stressors through the lens of his or her own belief system or world view.
