Despite interest in the nature of the traumatic event required to meet Criterion A for posttraumatic stress disorder (PTSD) as defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994), little attention has been paid to the diagnostic ramifications of linking PTSD symptoms to a single traumatic event in the context of multiple trauma exposures. In this study, 67 dually diagnosed clients with at least 2 potential Criterion A traumatic events completed the Posttraumatic Stress Diagnostic Scale twice, in counterbalanced order: once regarding their worst event and once regarding all events. When responding regarding their worst trauma, 53.7% met probable PTSD criteria. This rose to 67.2% when considering all traumas. Although preliminary, these results suggest that linking PTSD symptoms to a single traumatic event excludes a meaningful number of cases who are otherwise indistinguishable based on symptom profile.
尽管人们对符合《精神疾病诊断与统计手册》（DSM-IV；美国精神病学协会，1994）中创伤后应激障碍（PTSD）定义所需的创伤事件的性质很感兴趣，但很少有人关注将 PTSD 症状与多次创伤暴露背景下的单一创伤事件联系起来的诊断后果。在这项研究中，67 名双重诊断的患者至少有 2 个潜在的符合 A 标准的创伤事件，他们以平衡的顺序两次完成了创伤后应激障碍诊断量表：一次是关于他们最严重的事件，一次是关于所有事件。当他们对自己最严重的创伤做出反应时，53.7%符合 PTSD 可能诊断标准。当考虑所有创伤时，这一比例上升到 67.2%。尽管这些结果还初步的，但它们表明，将 PTSD 症状与单一创伤事件联系起来会排除大量其他方面无法通过症状特征区分的病例。
