Pain frequency has been shown to influence sensitization, psychological distress, and pain modulation. The present study examined if pain frequency moderates the relationship between pain catastrophizing and pain.
A non-clinical (247 students) and a clinical (223 pain patients) sample completed the Danish versions of the Pain Catastrophizing Scale (PCS), Beck Depression Inventory, and the State Trait Anxiety Inventory and rated pain intensity, unpleasantness and frequency.
In both samples, high pain frequency was found to moderate the association between pain catastrophizing and pain intensity, whereas low pain frequency did not. The psychometric properties and the factor structure of the Danish version of the PCS were confirmed.
This is the first study to validate the Danish version of the PCS and to show that pain frequency moderates the relationship between pain catastrophizing and reported pain in both non-clinical and clinical populations.
疼痛频率已被证明会影响敏感化、心理困扰和疼痛调节。本研究考察了疼痛频率是否会调节疼痛灾难化与疼痛之间的关系。
非临床样本（247 名学生）和临床样本（223 名疼痛患者）完成了丹麦版疼痛灾难化量表（PCS）、贝克抑郁量表和状态特质焦虑量表，并对疼痛强度、疼痛不愉快度和疼痛频率进行了评定。
在两个样本中，均发现高疼痛频率会调节疼痛灾难化与疼痛强度之间的关联，而低疼痛频率则不会。丹麦版 PCS 的心理测量学特性和因子结构得到了确认。
这是首次验证丹麦版 PCS 的研究，并表明疼痛频率在非临床和临床人群中调节疼痛灾难化与报告疼痛之间的关系。
