最近的研究表明，沉思是持续性创伤后应激障碍(PTSD)的有力预测因素。然而，到目前为止，沉思维持创伤后应激障碍症状的机制还知之甚少。对袭击幸存者的两项研究，一项横断面研究(N=81)和一项为期6个月的前瞻性纵向研究(N=73)，检查了反思性思维的几个方面，以确定反思性思维的哪些方面提供了与创伤后应激障碍的联系。目前的研究表明，沉思不仅被用作应对侵入性记忆的一种策略，而且还会触发这种记忆。反省的某些特征，如继续反省的强迫、非生产性思维的出现、“为什么”和“如果”类型的问题，以及反省前后的负面情绪，同时和前瞻性地与创伤后应激障碍显著相关。这些特征解释了创伤后应激障碍严重程度的差异明显多于仅仅存在反省，从而表明并不是所有的反省思维方式都同样不适应。
Recent studies have shown that rumination is a powerful predictor of persistent posttraumatic stress disorder (PTSD). However, to date, the mechanisms by which rumination maintains PTSD symptoms are little understood. Two studies Of assault survivors, a cross-sectional (N= 81) and a 6-month prospective longitudinal study (N = 73), examined several facets of ruminative thinking to establish which aspects of rumination provide the link to PTSD. The current investigation showed that rumination is not only used as a strategy to cope with intrusive memories but it also triggers such memories. Certain characteristics Of rumination, such as compulsion to continue ruminating, occurrence of unproductive thoughts, and "why" and "what if' type questions, as well as negative emotions before and after rumination, were significantly associated with PTSD, concurrently and prospectively. These characteristics explained significantly more variance in PTSD severity than the mere presence of rumination, thereby indicating that not all ways of ruminative thinking are equally maladaptive.
