本研究旨在通过大型慢性疼痛样本验证儿童和家长疼痛灾变量表，并确定儿童疼痛灾变的临床参考点。在儿童疼痛项目中评估的患者和家长（n= 697）完成了疼痛灾难化量表，儿童（PCS-C）和家长（PCS-P）报告，以及其他心理功能测量。该测量的心理测量特性进行了检查，以及人口统计学，疼痛，心理特征和疼痛灾难化之间的关系。从残疾、抑郁症状和焦虑水平的疼痛灾变差异中确定PCS-C的临床参考点。总的来说，我们没有发现对假设的三维结构的支持，并且由于地板/天花板效应，我们建议从PCS-P和PCS-C中删除项目7和8。11个项目的PCS-C作为一个单一的结构是最简洁的，而11个项目的PCS-P由两个因素组成。虽然在控制疼痛水平后，父母的灾难化与孩子的结局显著相关，但当考虑到孩子的灾难化时，它不再显著。当比较基于儿童结局的PCS-C分数时，在低、中、高灾难化水平上出现了显著差异。父母灾难化对结果的影响似乎可以通过其对儿童灾难化水平的影响来解释。最后，从这个大样本中得出的PCS-C参考点可以帮助临床医生进行评估和治疗计划，从而增加PCS-C在临床和研究目的中的效用。
The current study aimed to validate the child and parent pain catastrophizing scale in a large chronic pain sample and to identify child pain catastrophizing clinical reference points. Patients and parents (n= 697) evaluated at a pediatric pain program completed the Pain Catastrophizing Scale, child (PCS-C) and parent (PCS-P) report, along with additional measures of psychological functioning. The measure’s psychometric properties were examined, as well as relations across demographic, pain, and psychological characteristics and pain catastrophizing. Clinical reference points were identified for the PCS-C from differences in pain catastrophizing across levels of disability, depressive symptoms, and anxiety. Overall, we did not find support for the hypothesized three-dimension structure and recommend potentially removing items 7 and 8 for both the PCS-P and PCS-C due to floor/ceiling effects. The 11-item PCS-C is most parsimonious as a unitary construct, while the 11 item PCS-P is comprised of two factors. Although parent catastrophizing was significantly associated with child outcomes after controlling for pain level, it was no longer significant when accounting for child catastrophizing. When comparing PCS-C scores based on child outcomes, significant differences emerged for low, moderate, and high catastrophizing levels. It appears that the influence of parent catastrophizing on outcomes can be explained through its impact on child catastrophizing levels. Lastly, PCS-C reference points derived from this large sample can aid clinicians in assessment and treatment planning, in turn increasing the utility of the PCS-C for both clinical and research purposes.
