BACKGROUND
Rotator cuff-related shoulder pain (RCRSP) is a common musculoskeletal disorder. Chronic symptoms, high-level pain intensity, and disability are associated with high levels of pain catastrophizing in this condition. Although the Pain Catastrophizing Scale (PCS) is widely used to assess pain catastrophizing in individuals with chronic symptoms, its measurement properties are still unknown for assessing individuals with chronic RCRSP.
OBJECTIVES
To assess construct validity, reliability, and responsiveness of the PCS in individuals with chronic RCRSP.
METHODS
Eighty-three adult individuals with chronic RCRSP were included in this study. The assessment of construct validity was based on hypothesis testing. Spearman's rank correlation coefficient was used to verify the correlation of the total score and rumination, magnification, and helplessness subscales of the PCS with pain intensity, disability, and fear of movement. Test-retest reliability was analyzed with Intraclass Correlation Coefficient (ICC) and internal consistency was analyzed with Cronbach's alpha. Responsiveness was analyzed by effect sizes and the area under the receiver operating characteristic curve (AUC).
RESULTS
The PCS showed significant moderate correlation (rho ≥ 0.40) with fear of movement (95% confidence interval [CI]: 0.23, 0.70), pain intensity (95% CI: 0.14, 0.64), and disability (95% CI: 0.17, 0.66), except the rumination and magnification subscales, which showed significant weak correlation with pain intensity (95% CI: 0.14, 0.58) and disability (95% CI: 0.12, 0.56), respectively. PCS presented good reliability (ICC > 0.7, 95% CI: 0.63, 0.88), and adequate internal consistency (Cronbach alfa > 0.7) and responsiveness based on effect sizes and AUC.
CONCLUSION
The PCS is a valid, reliable, and responsive instrument for assessing individuals with chronic RCRSP.
背景
肩袖相关肩部疼痛（RCRSP）是一种常见的肌肉骨骼疾病。在这种情况下，慢性症状、高强度疼痛和残疾与高水平的疼痛灾难化有关。尽管疼痛灾难化量表（PCS）被广泛用于评估有慢性症状个体的疼痛灾难化情况，但对于评估慢性RCRSP个体，其测量特性仍不明确。
目的
评估PCS在慢性RCRSP个体中的结构效度、信度和反应度。
方法
本研究纳入了83名患有慢性RCRSP的成年个体。结构效度的评估基于假设检验。使用Spearman等级相关系数来验证PCS总分及沉思、放大和无助分量表与疼痛强度、残疾程度和运动恐惧之间的相关性。采用组内相关系数（ICC）分析重测信度，采用Cronbach's alpha分析内部一致性。通过效应量和受试者工作特征曲线下面积（AUC）分析反应度。
结果
PCS与运动恐惧（95%置信区间[CI]：0.23，0.70）、疼痛强度（95%CI：0.14，0.64）和残疾程度（95%CI：0.17，0.66）呈显著中度相关（rho≥0.40），但沉思和放大分量表分别与疼痛强度（95%CI：0.14，0.58）和残疾程度（95%CI：0.12，0.56）呈显著弱相关。PCS表现出良好的信度（ICC>0.7，95%CI：0.63，0.88），以及基于效应量和AUC的足够的内部一致性（Cronbach alfa>0.7）和反应度。
结论
PCS是评估慢性RCRSP个体的有效、可靠且具有反应度的工具。
