随着认知在PTSD中的作用越来越受到关注，本前瞻性研究探讨了创伤后认知与PTSD症状之间的过程和双向关系。1991年对包括前战俘在内的以色列退伍军人样本进行了评估，随后在2003年和2008年进行了随访。在三个时间点测量PTSD症状。关于自我和世界的认知被测量了两次。应用自回归交叉滞后（ARCL）建模策略，初始PTSD症状预测随后的负面认知，反之则不预测。此外，重复测量设计显示，慢性PTSD症状的个体具有相对消极的认知，并随着时间的推移进一步放大。更具体地说，在前战俘中记录了越来越多的消极认知。主要研究结果表明，消极认知是由创伤后应激障碍引起的，慢性创伤后应激障碍的致病结果随着时间的推移而扩大。对这些发现的讨论是在当前PTSD认知模型的背景下进行的。
With the growing interest in the role of cognitions in PTSD, this prospective study examined the course and bi-directional relationship between post-trauma cognitions and symptoms of PTSD. A sample of Israeli combat veterans, including former prisoners of war, was assessed in 1991, and later followed up in 2003 and 2008. PTSD symptoms were measured at three time points. Cognitions concerning the self and the world were measured twice. Applying Autoregressive Cross-Lagged (ARCL) modeling strategy, initial PTSD symptoms predicted subsequent negative cognitions but not vice versa. In addition, repeated measures design revealed that individuals with chronic PTSD symptoms had relatively negative cognitions that further amplified with time. More specifically, increasingly negative cognitions were documented among ex-prisoners of war. The main findings suggest that negative cognitions are fueled by PTSD and that in chronic PTSD there is an amplification of pathogenic outcomes over time. Discussion of the findings is in the context of current cognitive models of PTSD.
