我们研究了创伤暴露社区样本的创伤记忆的连贯性，其中30名成年人患有PTSD，30名没有PTSD。这两组人有相似的创伤类别，并在可能影响记忆连贯性的多个因素上进行了匹配。我们将参与者转录的口腔创伤记忆与他们最重要和最积极的记忆进行了比较。一套全面的28个措施的一致性，包括3个评级的参与者，7个评级的外部评级，和18个计算机评分的措施，提供了各种方法来定义和衡量一致性。MANOVA表明创伤，重要和积极的记忆之间的一致性差异，但不是诊断组之间或与这些记忆类型的相互作用。大多数差异在幅度上都很小;在某些情况下，创伤记忆比控制记忆更连贯，而不是更少。在存在差异的地方，结果与现有文献一致，表明创伤记忆不连贯以外的因素最有可能是维持PTSD及其治疗的核心。
We examined the coherence of trauma memories in a trauma-exposed community sample of 30 adults with and 30 without PTSD. The groups had similar categories of traumas and were matched on multiple factors that could affect the coherence of memories. We compared the transcribed oral trauma memories of participants with their most important and most positive memories. A comprehensive set of 28 measures of coherence including 3 ratings by the participants, 7 ratings by outside raters, and 18 computer-scored measures, provided a variety of approaches to defining and measuring coherence. A MANOVA indicated differences in coherence among the trauma, important, and positive memories, but not between the diagnostic groups or their interaction with these memory types. Most differences were small in magnitude; in some cases, the trauma memories were more, rather than less, coherent than the control memories. Where differences existed, the results agreed with the existing literature, suggesting that factors other than the incoherence of trauma memories are most likely to be central to the maintenance of PTSD and thus its treatment.
