克鲁格[1999年：Arch Gen Psychiatry 56：921-926]确定了精神病理学的三因素结构，其解释了在美国国家科摩罗调查（NCS）中发现的常见精神障碍的共变或分组[Kessler等人，1994：Arch Gen Psychiatry 51：8-19]。这三个基本分组包括一个外部化障碍因素和两个内部化障碍因素（焦虑痛苦和恐惧）。我们通过检查NCS（n= 5，877）中包含创伤后应激障碍（PTSD）诊断信息的大量子样本的额外数据扩展了这项研究。因子分析结果显示，PTSD表现出没有亲和力的恐惧因素定义的恐慌和恐惧症，而是加载的焦虑痛苦因素主要定义的情绪障碍。终生PTSD和12个月PTSD患病率数据的结果模式相同。这些研究结果的PTSD的分类及其病因学研究的意义进行了简要讨论。(C)2002 Wiley-Liss，Inc.
Krueger [1999: Arch Gen Psychiatry 56:921-926] identified a three-factor structure of psychopathology that explained the covariation or grouping of common mental disorders found in the U.S. National Comorbidity Survey (NCS) [Kessler et al., 1994: Arch Gen Psychiatry 51:8-19]. These three fundamental groupings included an externalizing disorders factor and two internalizing disorders factors (anxious-misery and fear). We extended this research through the examination of additional data from a large subsample of the NCS (n=5,877) that contained diagnostic information on posttraumatic stress disorder (PTSD). Factor analytic findings revealed that PTSD showed no affinity with the fear factor defined by panic and phobic disorders, and instead loaded on the anxious-misery factor defined primarily by mood disorders. An identical pattern of results emerged for both lifetime PTSD and 12-month PTSD prevalence figures. Implications of these findings for the classification of PTSD and research on its etiology are briefly discussed. (C) 2002 Wiley-Liss, Inc.
