This study was designed to investigate the equivalency and factor structure of the patients and significant others' version of pain catastrophizing scales in patients with chronic pain and their spouses who are not in pain.
Participants were 142 married couples in which 1 spouse reported chronic musculoskeletal pain. Confirmatory factor analyses were used to compare 4 models of pain catastrophizing, and to examine the invariance of the factor structure of the PCS-Patient version and the PCS-Significant other version in patients with chronic pain and their spouses.
The results indicated that the 2-factor oblique model provided an adequate fit to the data of both patients with chronic pain and their spouses who are not in pain. Moreover, it was found that when gender was controlled, the hypothesized factor structures of the PCS-patient version and the PCS-Significant other version were invariant. Indeed, it was revealed that the PCS-Patient version and the PCS-Significant other version measure the same factors in couples in which 1 of them have a chronic pain condition.
The findings of the current study showed that the 2-factor oblique model is the best fit in both samples (i.e., patients with chronic pain and their spouses). Therefore, it can be suggested that these versions can be used among patients and their spouses and the findings regarding them can be compared.

本研究旨在调查慢性疼痛患者及其无痛配偶的患者和重要他人疼痛灾难化量表版本的等效性和因子结构。
参与者为 142 对已婚夫妇，其中 1 名配偶报告患有慢性肌肉骨骼疼痛。采用验证性因子分析比较了疼痛灾难化量表的 4 种模型，并检验了慢性疼痛患者及其无痛配偶的疼痛灾难化量表患者版和疼痛灾难化量表重要他人版的因子结构不变性。
结果表明，双因素斜交模型为慢性疼痛患者及其无痛配偶的数据提供了较好的拟合。此外，当控制性别时，假设的疼痛灾难化量表患者版和疼痛灾难化量表重要他人版的因子结构是不变的。事实上，研究结果表明，在 1 方患有慢性疼痛的夫妇中，疼痛灾难化量表患者版和疼痛灾难化量表重要他人版测量的是相同的因素。
本研究的结果表明，双因素斜交模型在两个样本（即慢性疼痛患者及其配偶）中具有最佳拟合度。因此，可以建议在患者及其配偶中使用这些版本，并比较他们的研究结果。
