Disorganized trauma memory seems to play an important role in the pathogenesis of posttraumatic stress disorder (PTSD). However, it is unclear whether memory organization of nonautobiographical material (i.e., sequence memory) is also impaired in PTSD. A novel task designed to assess nonautobiographical memory for content and order information was administered to trauma survivors with (n = 26) and without PTSD (n = 55) as well as to nontraumatized healthy adults (n = 30). In addition, traumatized participants were asked to give a detailed narrative of the traumatic event and an unpleasant autobiographical event. Transcripts of both types of narratives were analyzed with regard to disorganization. Results indicated that trauma memories were more disorganized than memories of an unpleasant event in the PTSD group in comparison with the non-PTSD group. However, no differences were found for memory organization of nonautobiographical material among trauma survivors with and without PTSD and nontraumatized controls. With regard to memory accuracy of nonautobiographical material, group differences were more strongly associated with trauma exposure than with PTSD.
紊乱的创伤记忆似乎在创伤后应激障碍（PTSD）的发病机制中起重要作用。然而，尚不清楚非自传体材料的记忆组织（即序列记忆）在PTSD中是否也受损。一项旨在评估对内容和顺序信息的非自传体记忆的新任务，施测于患有PTSD（n = 26）和未患PTSD（n = 55）的创伤幸存者以及未受创伤的健康成年人（n = 30）。此外，要求受创伤的参与者详细叙述创伤事件和一件不愉快的自传体事件。对这两种叙述的文字记录进行了紊乱方面的分析。结果表明，与非PTSD组相比，PTSD组中创伤记忆比不愉快事件的记忆更紊乱。然而，在患有和未患PTSD的创伤幸存者以及未受创伤的对照组之间，非自传体材料的记忆组织未发现差异。关于非自传体材料的记忆准确性，组间差异与创伤暴露的关联比与PTSD的关联更强。
