惊恐障碍严重程度量表（PDSS）是一个由七个项目组成的工具，用于评估惊恐障碍的整体严重程度。该量表先前在有或没有广场恐怖症的恐慌症患者样本中证明了出色的心理测量特性。然而，尽管有一些因素分析的PDSS研究，但因素的数量并不完全一致。因此，我们在这项研究中的目的是评估两个相互竞争的模型与176例恐慌症患者样本数据的拟合性。符合DSM-IV惊恐障碍标准的患者（N = 176），伴或不伴广场恐怖症，接受结构化诊断评估和PDSS访谈。研究对象中，男性102人，女性74人。男性平均年龄为41.2岁（SD = 10.10），女性平均年龄为41.0岁（SD = 10.54）。考虑到以下指标：Tucker-Lewis指数= 0.94，比较拟合指数= 0.96，近似均方根误差= 0.08，标准化均方根残差= 0.04，认为具有两个相关因子的模型更适合描述数据。然后将这些结果与伴有广场恐怖症的惊恐障碍患者（n = 128）、无广场恐怖症患者（n = 48）和药物治疗后有惊恐障碍患者（n = 62）的亚组进行交叉验证。我们的研究结果表明，用西方样本建立和验证的相关双因素模型可以适当地推广到韩国的临床样本。此外，我们的研究结果支持韩国版PDSS的构念效度。
The Panic Disorder Severity Scale (PDSS) is a seven-item instrument used to rate the overall severity of panic disorder. This scale has previously evidenced excellent psychometric properties in a sample of patients with panic disorder, with or without agoraphobia. However, despite several factor-analytic PDSS studies, the number of factors has not been entirely consistent. Our objective in this study, then, was to evaluate the fit of two competing models to data collected with a sample of 176 patients with panic disorder. Patients (N = 176) who fulfilled DSM-IV criteria for panic disorder, with or without agoraphobia, underwent structured diagnostic assessments and PDSS interviews. Of the subjects, 102 were men and 74 were women. The mean age of the men was 41.2 (SD = 10.10) and of women, 41.0 (SD = 10.54). A model with two correlated factors was considered to be more appropriate in the description of the data with the following indices: Tucker-Lewis index = 0.94, comparative fit index = 0.96, root-mean-square error of approximation = 0.08, and standardized root-mean-square residual = 0.04. These results were then cross-validated with subgroups of patients with panic disorder with agoraphobia (n = 128), without agoraphobia (n = 48), and with panic disorder after phamacotherapy (n = 62). Our results indicated that the correlated two-factor model developed and validated using Western samples could be appropriately generalized to Korean clinical samples. Furthermore, our results support the construct validity of the Korean version of the PDSS.
