本研究调查了937名大学生的创伤事件和创伤后应激障碍(PTSD)症状的终生发生率。受试者对他们一生中经历的创伤事件进行评级，并根据他们所面临的“最大压力”事件，对客观应激源维度、创伤后应激障碍和肿瘤周围反应进行完整的测量。约67%的受访者报告了至少一次创伤性事件。估计有4%的完整样本(12%的精神创伤患者)在过去一周内符合创伤后应激障碍标准。在控制了易感因素和客观特征后，瘤周反应仍然是创伤后应激障碍症状的强烈预测因素。关于创伤事件的即时反应作为创伤后应激障碍症状的潜在先兆的结果进行了讨论。
This study investigated lifetime prevalence of traumatic events and posttraumatic stress disorder (PTSD) symptoms among 937 college students. Participants rated their lifetime experiences of traumatic events and, in response to their "most stressful" event, completed measures of objective stressor dimensions, PTSD, and peritraumatic reactions. Approximately 67% of respondents reported at least one traumatic event. An estimated 4% of the full sample (12% of traumatized individuals) met PTSD criteria within the past week. After controlling for vulnerability factors and objective characteristics, peritraumatic reactions remained strongly predictive of PTSD symptoms. Results are discussed with respect to immediate reactions to traumatic events as potential precursors of PTSD symptomatology.
