Abstract

BACKGROUND The factor structure of the Pain Catastrophizing Scale (PCS) has rarely been adequately analyzed (e.g., performing principal component analyses rather than factorial approximations). We aimed to evaluate the psychometric properties of the PCS through a variety of exploratory and confirmatory factorial approaches. METHOD Three hundred ninety-four Chilean patients with musculoskeletal pain were included (age, M = 49.61, SD = 18.00; 71.57% women). Eight factorial models were proposed to analyze the structure of the data. In addition, validity evidence of the PCS based on relationships with other variables were analyzed considering pain intensity and kinesiophobia. RESULTS The results suggest a unidimensional structure. Models with more than one dimension exhibited undesirable factor loadings or inadequate indices of fit. Based on these results, a short version of the scale composed of 4 items is proposed (PCS-4). The PCS-4 scores demonstrated high levels of invariance between sex, chronicity, and education groups and also were associated with pain and kinesiophobia. CONCLUSIONS The results of the PCS-4 Spanish version showed evidence of reliability and validity for adequately measuring pain catastrophizing in Chileans who suffer from musculoskeletal pain. The PCS-4 is a short form that should be explored in future studies (e.g., in other Spanish-speaking populations).

肌肉骨骼疼痛患者PCS和PCS-4的心理测量特性。
痛灾变量表(PCS)的因子结构很少得到充分的分析(例如,执行主成分分析而不是因子近似)。我们的目的是通过各种探索性和验证性的析因方法来评估PCS的心理测量特性。方法纳入394例智利骨骼肌疼痛患者(年龄,M = 49.61, SD = 18.00;71.57%的女性)。提出了8个因子模型来分析数据的结构。此外,考虑到疼痛强度和运动恐惧症,分析了基于其他变量的PCS效度证据。结果样品呈单维结构。具有多个维度的模型表现出不希望的因子负荷或不适当的拟合指数。根据这些结果,提出了一个由4个项目组成的简短版本(PCS-4)。PCS-4得分在性别、慢性病和教育程度组之间表现出高度的不变性,并且与疼痛和运动恐惧症有关。结论PCS-4西班牙语版本的结果显示了充分衡量智利肌肉骨骼疼痛患者疼痛灾变的信度和效度。PCS-4是一种简短的形式,应该在未来的研究中加以探索(例如,在其他西班牙语人口中)。
