Good correlation has been shown between pain scores derived from 4 different rating scales. The correlation was maintained when presentation of the scales was separated by a series of questions and by physical examination. There is good evidence that the 4 scales are measuring the same underlying pain variable as they calibrate well. There is also evidence that an 11-point (0-10) numerical rating scale performs better than both a 4-point simple descriptive scale or a continuous (visual analogue) scale.
研究表明,源自4种不同评分量表的疼痛评分之间具有良好的相关性。当通过一系列问题和体格检查将量表的呈现分开时,这种相关性依然存在。有充分证据表明,这4种量表测量的是同一个潜在疼痛变量,因为它们校准良好。也有证据表明,11分制(0 - 10)数字评分量表的表现优于4分简单描述性量表或连续(视觉模拟)量表。
