If the symptoms of acute stress reaction or ASD continue together with persistent re-experiencing of the traumatic event (e.g., in images, thoughts, dreams) combined with avoidance of stimuli arousing recollection of the trauma and physiological symptoms of arousal, a diagnosis of PTSD is made (DSM-IV requires 4 weeks symptomatology for the diagnosis of PTSD).

如果避免了唤起对创伤的回忆和唤醒的生理症状的刺激，但急性应激反应或ASD的症状持续存在，并持续重复经历创伤事件(例如，在图像、思维、梦境中)，则做出PTSD的诊断(DSM-IV需要4周的症状学来诊断PTSD)。
