The course of posttraumatic stress disorder (PTSD) symptoms in the month after trauma exposure has not been determined adequately. Symptom group C (avoidance/numbing) has been identified retrospectively as a marker for PTSD, but prospective studies are needed to determine whether these symptoms can provide substantially earlier identification of those who will have PTSD 1 month after trauma exposure.
We evaluated 42 patients hospitalized for traumatic injuries over the first post-injury month to track development of posttraumatic symptoms.
Symptoms emerged rapidly, with group B (intrusion) and group D (hyperarousal) symptoms occurring earlier than group C symptoms. At 1 week, group C criteria accurately predicted who would develop PTSD by 1 month, and by 2 weeks, group C criteria also predicted who would not develop PTSD by 1 month.
The findings, if replicated, may permit earlier identification of PTSD and more timely, appropriate treatment.
创伤暴露后一个月内创伤后应激障碍（PTSD）症状的发展过程尚未得到充分确定。症状C组（回避/麻木）已被回顾性地确定为PTSD的一个标志物，但需要前瞻性研究来确定这些症状是否能在创伤暴露后1个月时更早地识别出那些将会患PTSD的人。
我们评估了42名因创伤性损伤住院的患者在受伤后的第一个月内创伤后症状的发展情况。
症状出现迅速，B组（侵入性）和D组（过度警觉）症状比C组症状出现得更早。在1周时，C组标准能准确预测谁会在1个月时发展为PTSD，到2周时，C组标准也能预测谁不会在1个月时发展为PTSD。
如果这些发现得到重复验证，可能会实现对PTSD的更早识别以及更及时、恰当的治疗。
