This study investigated the psychometric properties of eight pain intensity measures used with chronic low back pain patients. All measures were similar in terms of scale distribution and rates of incorrect responses, with all scales apart from the Pain Rating Index significantly correlated. Principal axis factoring of data from 92 patients indicated the presence of one general factor on which all pain intensity measures except the Pain Rating Index loaded. The 101-point Numeric Rating Scale and the Box Scale had the strongest relationship, with loadings of 0.90. The Numeric Rating Scale and the Box Scale appear to be the scales of choice for the measurement of pain intensity in the low back pain patient.
本研究调查了用于慢性下腰痛患者的八项疼痛强度测量指标的心理测量特性。所有测量指标在量表分布和错误反应率方面相似，除疼痛评定指数外，所有量表均显著相关。对92名患者的数据进行主成分因子分析表明，存在一个一般因子，除疼痛评定指数外，所有疼痛强度测量指标均负荷于此因子。101点数字评定量表和方格量表的关系最为密切，负荷量为0.90。数字评定量表和方格量表似乎是测量下腰痛患者疼痛强度的首选量表。
