这项研究检查了三个不同荷兰语样本中疼痛灾难化量表的因子结构：550 名无痛学生、162 名慢性腰痛患者和 100 名纤维肌痛患者。验证性因素分析用于比较三种不同的疼痛灾难化模型（一个因素、两个间接因素、三个间接因素），并研究三个不同样本的因素结构的不变性。结果表明，具有四项沉思因子、三项放大因子和六项无助因子的三因子倾斜模型为三个样本中的数据提供了最佳拟合。此外，我们发现该模型可以被认为在三个样本（无痛学生、慢性腰痛患者和纤维肌痛患者）和性别之间是不变的，这表明在不同的亚组中测量了相同的过程。 (C) 2002 年国际疼痛研究协会。由 Elsevier Science B.V. 出版。保留所有权利。
This study examined the factor structure of the Pain Catastrophizing Scale in three different Dutch-speaking samples: 550 pain-free students, 162 chronic low back pain patients, and 100 fibromyalgia patients. Confirmatory factor analyses were used to compare three different models of pain catastrophizing (one factor, two oblique factors, three oblique factors), and to investigate the invariance of the factor structure across the three different samples. The results indicated that a three-factor oblique model with a four-item rumination factor, a three-item magnification factor, and a six-item helplessness factor provided the best fit to the data in the three samples. Furthermore, it was found that this model could be considered as invariant across three samples (pain-free students, chronic low back pain patients, and fibromyalgia patients) and across gender, indicating that the same processes are measured in different subgroups.
