Abstract

Background: Catastrophizing is an important psychological construct in mediating the behavioral response toward pain.

Objective: The purpose of this study is to examine the psychometric properties of the Pain Catastrophizing Scale (PCS) in Greek clinical population.

Methods: The scale was administered in 376 patients with chronic cervical and lumbar pain. Test-retest reliability, internal consistency (Cronbach $α$ ) and concurrent validity were assessed. Exploratory (EFA) and Confirmatory Factor Analysis (CFA) were used to test the factorial validity of the hypothesized three factor structure.

Results: The PCS factors suggested high levels of test-retest reliability, whereas Cronbachs' $α$ values were acceptable. The EFA yielded a three-factor solution and indicated a marginal fit to the data. CFA procedures indicated a rather acceptable fit to the data. The concurrent validity of the instrument was confirmed.

Conclusion: PCS seems to be a reliable and valid instrument in Greek patients with chronic cervical and lumbar pain.

希腊临床人群疼痛灾变量表的跨文化适应。

背景:灾难化是调节疼痛行为反应的重要心理构念。目的:研究希腊临床人群疼痛灾难化量表(PCS)的心理测量特征。方法:对376例慢性颈腰痛患者进行评定。评估重测信度、内部一致性(Cronbach α)和并发效度。采用探索性因子分析(EFA)和验证性因子分析(CFA)来检验假设的三因素结构的因子效度。结果:PCS因子具有较高的重测信度，cronbach α值可接受。EFA产生了一个三因素解决方案，并表明数据的边际拟合。CFA程序表明与数据的拟合相当可接受。同时确认了该文书的有效性。结论:PCS似乎是治疗希腊慢性腰颈痛患者的一种可靠有效的工具。
