The 0-10 Numerical Rating Scale (NRS-11) is widely used with Arabic-speaking pediatric populations. However, there is no data about its validity or reliability. Thus, the aims of this research were to translate the NRS-11 into Arabic and study its dimensionality and construct (convergent and discriminant) validity, and reliability.
A group of 190 Lebanese students between 8 and 18 years old participated. Participants were interviewed online and asked to imagine themselves in a hypothetical painful situation and rate the expected pain intensity using the NRS-11-Arabic and an Arabic version of the Visual Analogue Scale (VAS-Arabic). They were also requested to respond to the pediatric Arabic version of the Pain Catastrophizing Scale (PCS-Arabic). Data collection lasted for a month.
Data showed that the NRS-11-Arabic and the VAS-Arabic scores measure the same common construct. In addition, they showed strong statistically significant correlations between NRS-11 and VAS (ranging from 0.83 for the whole sample and 0.83 and 0.84 for the 8-12-year-olds and the 13-18-year-olds, which support its construct validity). These correlations were higher than those between the NRS-11-Arabic and the PCS-Arabic, which support the discriminant validity of NRS-11-Arabic scores. Test-retest reliability was 0.86 for the whole sample, and 0.89 and 0.82 for the 8-12-year-olds and the 13-18-year-olds, respectively, which shows the reliability of the NRS-11-Arabic scores.
The data provide preliminary evidence of the unidimensionality, validity and reliability of the NRS-11-Arabic scores, thus supporting its use in clinical and research activities involving Arabic-speaking pediatric samples.
0-10 数字评分量表（NRS-11）在讲阿拉伯语的儿科人群中广泛使用。然而，其有效性和可靠性数据尚缺乏。因此，本研究旨在将 NRS-11 翻译成阿拉伯语，并研究其维度和结构（聚合和区分）的有效性和可靠性。
一组 190 名 8-18 岁的黎巴嫩学生参与了本研究。参与者通过在线访谈的方式被要求想象自己处于一种假设的疼痛情境中，并使用 NRS-11-阿拉伯语和阿拉伯语版视觉模拟量表（VAS-阿拉伯语）对预期的疼痛强度进行评分。他们还被要求对儿科阿拉伯语版疼痛灾难化量表（PCS-阿拉伯语）做出反应。数据收集持续了一个月。
数据显示，NRS-11-阿拉伯语和 VAS-阿拉伯语评分测量的是相同的共同结构。此外，它们之间存在强烈的统计学显著相关性（整个样本的范围从 0.83 到 8-12 岁和 13-18 岁的 0.83 和 0.84，支持其结构有效性）。这些相关性高于 NRS-11-阿拉伯语和 PCS-阿拉伯语之间的相关性，支持 NRS-11-阿拉伯语评分的区分有效性。整个样本的重测信度为 0.86，8-12 岁和 13-18 岁的重测信度分别为 0.89 和 0.82，表明 NRS-11-阿拉伯语评分的可靠性。
这些数据提供了初步证据，表明 NRS-11-阿拉伯语评分具有单一维度、有效性和可靠性，从而支持其在涉及讲阿拉伯语的儿科样本的临床和研究活动中的使用。
