Despite wide usage of the Numerical Rating Scale (NRS) for self-report of pain intensity in clinical practice with children and adolescents, validation data are lacking. We present here three datasets from studies in which the NRS was used together with another self-report scale. Study A compared post-operative pain ratings on the NRS with scores on the Faces Pain Scale-Revised (FPS-R) in 69 children age 7-17 years who had undergone a variety of surgical procedures. Study B compared post-operative pain ratings on the NRS with scores on the Visual Analogue Scale (VAS) in 29 children age 9-17 years who had undergone pectus excavatum repair. Study C compared ratings of remembered immunization pain in 236 children who comprised an NRS group and a sex- and age-matched VAS group. Correlations of the NRS with the FPS-R and VAS were r=0.87 and 0.89 in Studies A and B, respectively. In Study C, the distributions of scores on the NRS and VAS were very similar except that scores closest to the no pain anchor were more likely to be selected on the VAS than the NRS. The NRS can be considered functionally equivalent to the VAS and FPS-R except for very mild pain (<1/10). We conclude that use of the NRS is tentatively supported for clinical practice with children of 8years and older, and we recommend further research on the lower age limit and on standardized age-appropriate anchors and instructions for this scale.
尽管数字评定量表（NRS）在儿童和青少年临床实践中广泛用于自我报告疼痛强度，但缺乏验证数据。我们在此展示三项研究的数据集，这些研究中NRS与另一种自我报告量表一起使用。研究A比较了69名7至17岁接受各种外科手术的儿童在NRS上的术后疼痛评分与面部疼痛量表修订版（FPS-R）的得分。研究B比较了29名9至17岁接受漏斗胸修复手术的儿童在NRS上的术后疼痛评分与视觉模拟量表（VAS）的得分。研究C比较了236名儿童（包括一个NRS组和一个性别与年龄匹配的VAS组）对记忆中的免疫接种疼痛的评分。在研究A和B中，NRS与FPS-R和VAS的相关性分别为r = 0.87和0.89。在研究C中，NRS和VAS的得分分布非常相似，只是在VAS上比在NRS上更有可能选择最接近无疼痛锚定的得分。除了非常轻微的疼痛（<1/10）外，NRS在功能上可被视为等同于VAS和FPS-R。我们得出结论，对于8岁及以上儿童的临床实践，暂时支持使用NRS，并且我们建议进一步研究该量表的年龄下限以及标准化的适合年龄的锚定和使用说明。
