健康素养（HL）是一个重要的公共卫生问题。目前的措施在长度和/或可接受性方面存在缺陷。美国开发的最新生命体征（NVS）健康素养工具使用营养标签测量阅读理解和算术技能，只需3分钟即可管理，并已被证明是可接受的研究对象。本研究旨在针对英国人群进行修订和验证。我们采用了一个三阶段的过程;（1）与学术和临床专家一起进行的德尔菲研究，以修改NVS标签，以反映英国营养标签（2）基于社区的认知测试，以评估和提高测试的理解和可接受性（3）根据公认的健康素养标准测试验证NVS-UK，成人功能性健康素养测试（TOFHLA）（Pearson’s r和受试者工作特征（ROC）曲线下面积）和受试者教育水平。样本量计算表明需要250名参与者。入选标准为年龄18-75岁，能够用英语匡威。我们排除了在健康领域工作的人和那些视力受损或由于认知障碍或无法用英语匡威而无法接受采访的人。在德尔菲研究中，28位专家达成共识（3个周期）。认知测试（80名参与者）产生了一个不需要进一步改进的工具。验证测试（337名参与者）显示出较高的内部一致性（Cronbach's Alpha = 0.74）。对TOFHLA的验证表明Pearson相关系数为0.49，ROC曲线下面积为0.81。NVS-UK是HL的有效指标。它的可接受性和易于应用使其成为在英国使用的理想工具。它在公共卫生研究中有潜在的用途，包括流行病学调查和随机对照试验，并使从业人员能够根据患者的需要量身定制护理。
Health literacy (HL) is an important public health issue. Current measures have drawbacks in length and/or acceptability. The US-developed Newest Vital Sign (NVS) health literacy instrument measures both reading comprehension and numeracy skills using a nutrition label, takes 3 minutes to administer, and has proven to be acceptable to research subjects. This study aimed to amend and validate it for the UK population. We used a three-stage process; (1) a Delphi study with academic and clinical experts to amend the NVS label to reflect UK nutrition labeling (2) community-based cognitive testing to assess and improve ease of understanding and acceptability of the test (3) validation of the NVS-UK against an accepted standard test of health literacy, the Test of Functional Health Literacy in Adults (TOFHLA) (Pearson’s r and the area under the Receiver Operating Characteristic (ROC) curve) and participant educational level. A sample size calculation indicated that 250 participants would be required. Inclusion criteria were age 18–75 years and ability to converse in English. We excluded people working in the health field and those with impaired vision or inability to undertake the interview due to cognitive impairment or inability to converse in English. In the Delphi study, 28 experts reached consensus (3 cycles). Cognitive testing (80 participants) yielded an instrument that needed no further refinement. Validation testing (337 participants) showed high internal consistency (Cronbach’s Alpha = 0.74). Validation against the TOFHLA demonstrated a Pearson’s r of 0.49 and an area under the ROC curve of 0.81. The NVS-UK is a valid measure of HL. Its acceptability and ease of application makes it an ideal tool for use in the UK. It has potential uses in public health research including epidemiological surveys and randomized controlled trials, and in enabling practitioners to tailor care to patient need.
