Subthreshold post-traumatic stress disorder (PTSD) is more prevalent than PTSD, yet its role as a potential risk factor for PTSD is unknown. To address this gap, we analysed data from a 7-year, prospective national cohort of USA veterans. Of veterans with subthreshold PTSD at wave 1, 34.3% developed PTSD compared with 7.6% of trauma-exposed veterans without subthreshold PTSD (relative risk ratio 6.4). Among veterans with subthreshold PTSD, specific PTSD symptoms, greater age, cognitive difficulties, lower dispositional optimism and new-onset traumas predicted incident PTSD. Results suggest that preventive interventions targeting subthreshold PTSD and associated factors may help mitigate risk for PTSD in USA veterans.

亚阈值创伤后应激障碍作为创伤后应激障碍的危险因素:来自美国退伍军人样本的结果

亚阈值创伤后应激障碍 (PTSD) 比 PTSD 更普遍,但其作为 PTSD 潜在危险因素的作用尚不清楚。为了解决这一差距,我们分析了来自美国退伍军人的 7 年前瞻性国家队列的数据。在第 1 波有亚阈值 PTSD 的退伍军人中,34.3% 发生了 PTSD,而没有亚阈值 PTSD 的受创伤的退伍军人中有 7.6%(相对风险比为 6.4)。在具有亚阈值 PTSD 的退伍军人中,特定的 PTSD 症状、更大的年龄、认知困难、较低的性格乐观和新发的创伤预示着事件 PTSD。结果表明,针对阈下 PTSD 和相关因素的预防性干预措施可能有助于降低美国退伍军人 PTSD 的风险。
