人们发现，疼痛灾难化是腰痛患者残疾和缺勤天数的重要预测因素。最常用的结果测量，以确定疼痛灾难化是疼痛灾难化量表（PCS）。为了使PCS能够在挪威语患者的临床环境和研究中使用，必须翻译PCS。因此，本研究的目的是翻译和跨文化适应PCS到挪威和测试内部的一致性，结构效度和再现性的PCS。PCS在进行心理测量特性测试之前进行了翻译。年龄在18岁或以上的亚急性或慢性非特异性腰痛患者从初级和二级护理招募。通过评价数据质量（缺失、下限和上限效应）、主成分分析、内部一致性（Cronbach α）和结构效度（斯皮尔曼rho）评估PCS的有效性。再现性分析包括测量的标准误、最小可检测变化、一致性限度和组内相关系数。共纳入38名男性和52名女性（n = 90）进行基线检测，平均（SD）年龄为47.6（11.7）岁。61例患者的亚组被纳入进行重测评估。挪威的PCS很容易理解。主成分分析结果支持三因素结构，PCS总分（α 0.90）、沉思（α 0.83）和无助（α 0.86）的内部一致性较好，但放大因子（α 0.53）的内部一致性较差。总的来说，86%的相关性分析符合预定义的假设。可靠性分析显示PCS总分和分量表的组内相关系数为0.74 - 0.87。PCS总评分（范围0-52分）显示测量标准误为4.6分，95%最小可检测变化估计值为12.8分。挪威PCS总分显示出可接受的心理测量学属性的可理解性，一致性，结构效度和再现性时，适用于亚急性或慢性LBP患者从不同的临床设置。我们的研究支持将PCS总分用于临床或研究目的，以识别或评估疼痛灾难化。
Pain catastrophizing has been found to be an important predictor of disability and days lost from work in patients with low back pain. The most commonly used outcome measure to identify pain catastrophizing is the Pain Catastrophizing Scale (PCS). To enable the use of the PCS in clinical settings and research in Norwegian speaking patients, the PCS had to be translated. The purpose of this study was therefore to translate and cross-culturally adapt the PCS into Norwegian and to test internal consistency, construct validity and reproducibility of the PCS. The PCS was translated before it was tested for psychometric properties. Patients with subacute or chronic non-specific low back pain aged 18 years or more were recruited from primary and secondary care. Validity of the PCS was assessed by evaluating data quality (missing, floor and ceiling effects), principal components analysis, internal consistency (Cronbach’s alpha), and construct validity (Spearman’s rho). Reproducibility analyses included standard error of measurement, minimum detectable change, limits of agreement, and intraclass correlation coefficients. A total of 38 men and 52 women (n = 90), with a mean (SD) age of 47.6 (11.7) years, were included for baseline testing. A subgroup of 61 patients was included for test-retest assessments. The Norwegian PCS was easy-to-comprehend. The principal components analysis supported a three-factor structure, internal consistency was satisfactory for the PCS total score (α 0.90) and the subscales rumination (α 0.83) and helplessness (α 0.86), but not for the subscale magnification (α 0.53). In total, 86% of the correlation analyses were in accordance with predefined hypothesis. The reliability analyses showed intraclass correlation coefficients of 0.74 − 0.87 for the PCS total score and subscales. The PCS total score (range 0–52 points) showed a standard error of measurement of 4.6 points and a 95% minimum detectable change estimate of 12.8 points. The Norwegian PCS total score showed acceptable psychometric properties in terms of comprehensibility, consistency, construct validity, and reproducibility when applied to patients with subacute or chronic LBP from different clinical settings. Our study support the use of the PCS total score for clinical or research purposes identifying or evaluating pain catastrophizing.
