关于创伤后应激障碍(PTSD)的结构以及如何最好地概念化和衡量这一障碍，文献中一直存在着关注。我们使用747名退伍军人的横断面、多部位初级保健样本，将传统的DSM-IV PTSD症状标准(即，来自B、C和D组的症状)与修订的标准集进行了比较，修订后的标准集省略了重叠的情绪和其他焦虑症状在FTSD患病率、PTSD诊断干酪率、相关精神共病、功能状态和结构有效性方面的影响。在剔除了理论上与情绪和其他焦虑障碍重叠的项目后，使用两个标准集的PTSD患病率是相同的(即12%)。总体而言，在两组诊断标准中，创伤后应激障碍的干酪性、相关的精神疾病共病、功能状态和结构效度在统计学上几乎没有显著差异。这些数据进一步支持，移除与其他精神障碍重叠的项目不会显著影响创伤后应激障碍的患病率、相关的共病和功能障碍，或其结构有效性。虽然修订的标准集代表了一个更简约的模型，但目前的研究结果总体上支持创伤后应激障碍的强大结构效度。这些研究结果对研究和临床实践的意义进行了讨论。爱思唯尔有限公司出版。
Ongoing concerns exist in the literature regarding the construct of posttraumatic stress disorder (PTSD) and how to best conceptualize and measure this disorder. We compared the traditional DSM-IV PTSD symptom criteria (i.e., symptoms from clusters B, C. and D) to a revised criterion set that omits overlapping mood and other anxiety symptoms on FTSD prevalence, PTSD diagnostic caseness, associated psychiatric comorbidity, functional status, and structural validity using a cross-sectional, multi-site primary care sample of 747 veterans. After removing items theorized to overlap with mood and other anxiety disorders, PTSD prevalence was identical using both criterion sets (i.e., 12%). Overall, there were few statistically significant differences in PTSD caseness, associated psychiatric comorbidity, functional status, and structural validity across the two diagnostic criterion sets. These data provide further support that removing items that overlap with other psychiatric disorders does not significantly impact the prevalence of PTSD, its associated comorbidity and functional impairment, or its structural validity. Although the revised criterion set represents a more parsimonious model, the current study findings generally support the strong construct validity of PTSD. The implications of these study findings for research and clinical practice are discussed. Published by Elsevier Ltd.
