The purpose of the current study was to examine the DSM-IV E and F criteria when using self-report measures of Posttraumatic Stress Disorder (PTSD). According to DSM-IV there are six core criteria required for a PTSD diagnosis including specific trauma characteristics, re-experiencing, avoidance, hyperarousal, duration, and impairment level. The Impact of Events Scale (IES) is a widely used self-report measure designed to measure PTSD symptoms. It has recently been suggested that the IES may produce misleading results, making emotional reactions to obviously non-traumatic events look like PTSD. In two separate studies, when duration (E criterion) and subjective impairment (F criterion) were included, the rates of those meeting PTSD criteria dropped from 20% to 3%. In addition, only 30% of events identified by a trauma history questionnaire met the DSM-IV definition of a traumatic event. The results have implications for the use of self-report measures in the assessment of PTSD.
本研究旨在考察使用创伤后应激障碍（PTSD）自评量表时DSM-IV 的 E 和 F 标准。根据 DSM-IV，PTSD 诊断需要符合六个核心标准，包括特定的创伤特征、再体验、回避、过度警觉、持续时间和损伤程度。事件影响量表（IES）是一种广泛使用的自评量表，用于测量 PTSD 症状。最近有人提出，IES 可能会产生误导性结果，使对明显非创伤性事件的情绪反应看起来像 PTSD。在两项独立的研究中，当包括持续时间（E 标准）和主观损伤（F 标准）时，符合 PTSD 标准的比例从 20%降至 3%。此外，创伤史问卷确定的只有 30%的事件符合 DSM-IV 对创伤性事件的定义。研究结果对使用自评量表评估 PTSD 具有启示意义。
