Abstract

Objective

To analyze the measurement properties of the Brazilian version of the Pain Catastrophizing Scale (PCS) in patients with chronic cancer pain.

Methods

The study was conducted in two hospitals in northeastern Brazil. In addition to the PCS, the following instruments were used: Barthel Index, Hospital Anxiety and Depression Scale (HADS), and Edmonton Symptom Assessment System (ESAS). The measurement properties tested were reliability, internal consistency, and structural and construct validity.

Results

The sample consisted of 120 cancer patients. The majority of the sample was female (65.8%) and had a basic education (60%). Thirty-three different types of cancer were identified; the most prevalent were uterine cancer (22.5%) and leukemia (10%). We identified the presence of a domain in the PCS in the exploratory factor analysis according to the fit indices: Kaiser–Meyer–Olkin test = 0.80 and p value <0.001 in Bartlett's sphericity test. Adequate test–retest reliability (intraclass correlation coefficient = 0.80) and internal consistency (Cronbach's alpha = 0.89) were observed. Correlations between the PCS and HADS subscales fell within the 0.30–0.50 range, as hypothesized. We identified no floor or ceiling effects (<15%).

Conclusion

The PCS presented adequate measurement properties to assess catastrophizing in patients with chronic cancer pain, becoming a useful tool to evaluate these patients.

疼痛灾难量表（PCS）在巴西慢性癌症疼痛患者：一项验证研究。

目的：分析巴西版疼痛灾变量表（PCS）在慢性癌性疼痛患者中的测量特性。方法：本研究在巴西东北部的两家医院进行。除PCS外，还采用了Barthel指数、医院焦虑抑郁量表（HADS）和埃德蒙顿症状评估系统（ESAS）。测试的测量性质包括信度、内部一致性、结构效度和构念效度。结果：样本包括120名癌症患者。大多数样本为女性（65.8%），受过基础教育（60%）。他们发现了33种不同类型的癌症；最常见的是子宫癌（22.5%）和白血病（10%）。我们在探索性因子分析中发现PCS中存在一个域，根据拟合指数：Kaiser-Meyer-Olkin检验=0.80和p值。结论：PCS具有足够的测量特性来评估慢性癌性疼痛患者的灾难化，成为评估这些患者的有用工具。
