This work represents the first attempt to validate, for the Italian population, the most widespread health literacy assessment tool: the Newest Vital Sign (NVS).
The UK version of this tool was adapted for Italy using a translation/back-translation process. A web-based survey was then administered to a multidisciplinary panel of experts to assess its face validity. Finally, a preliminary study of construct validity was conducted, focusing on efficiency, comprehensibility, reliability, and sensitivity of the items of the test. For the evaluation of these dimensions we adopted Pearson's r correlation and calculated the average scores obtained for the subscales.
Data analysis shows that the NVS-IT can be considered, under every aspect, an adequate tool for the assessment of individual health literacy grade level, given the optimal correlation among the experts' judgments and the average scores above the acceptability threshold.
Our study aims to encourage use of the NVS for the Italian population and, furthermore, introduce a scientific approach to health literacy, an issue that is gaining interest even in our country, though, to date, this has mainly resulted in the production of theoretical works.
本研究首次尝试针对意大利人群验证最广泛使用的健康素养评估工具：最新生命体征量表（NVS）。
该工具的英国版本通过翻译/回译过程进行了意大利语改编。随后对一个多学科专家小组进行了基于网络的调查，以评估其表面效度。最后，进行了一项关于结构效度的初步研究，重点关注测试项目的效率、可理解性、可靠性和敏感性。为了评估这些维度，我们采用了皮尔逊相关系数r，并计算了各分量表的平均得分。
数据分析表明，鉴于专家判断与高于可接受阈值的平均得分之间具有最佳相关性，NVS-IT在各个方面都可被视为评估个人健康素养等级水平的合适工具。
我们的研究旨在鼓励意大利人群使用NVS，此外，引入一种科学的健康素养研究方法，尽管到目前为止，这个问题在我国主要产生了一些理论著作，但它正日益受到关注。
