目前用于卫生保健机构的健康素养筛查工具要么太长，无法常规使用，要么只有英语版本。我们的目标是开发一个快速，准确的筛选测试有限的识字能力，在英语和Spanish.METHODS我们管理候选项目的新工具，也测试功能健康素养的成年人（TOFHLA）讲英语和讲西班牙语的初级保健患者。我们测量内部一致性与克朗巴赫的α和评估标准效度通过测量相关性与TOFHLA分数。使用TOFLHA分数< 75定义有限的识字，我们绘制了受试者操作特征（ROC）曲线和计算似然比的截止分数的新instrument.Results的最后一个工具，最新的生命体征（NVS），是一个营养标签，伴随着6个问题，需要3分钟的管理。它是可靠的（Cronbach α在英语中> 0.76，在西班牙语中> 0.69），并与TOFHLA相关。ROC曲线下面积为英语0.88，西班牙语0.72。超过4个正确的答案是不太可能有低识字，而少于4个正确的答案表明有限literation.Conclusion NVS的可能性是适合作为一个快速筛查测试有限的识字在初级卫生保健机构使用。
PURPOSE Current health literacy screening instruments for health care settings are either too long for routine use or available only in English. Our objective was to develop a quick and accurate screening test for limited literacy available in English and Spanish.METHODS We administered candidate items for the new instrument and also the Test of Functional Health Literacy in Adults (TOFHLA) to English-speaking and Spanish-speaking primary care patients. We measured internal consistency with Cronbach's alpha and assessed criterion validity by measuring correlations with TOFHLA scores. Using TOFLHA scores < 75 to define limited literacy, we plotted receiver-operating characteristics (ROC) curves and calculated likelihood ratios for cutoff scores on the new instrument.RESULTS The final instrument, the Newest Vital Sign (NVS), is a nutrition label that is accompanied by 6 questions and requires 3 minutes for administration. It is reliable (Cronbach alpha > 0.76 in English and 0.69 in Spanish) and correlates with the TOFHLA. Area under the ROC curve is 0.88 for English and 0,72 for Spanish versions. Patients with more than 4 correct responses are unlikely to have low literacy, whereas fewer than 4 correct answers indicate the possibility of limited literacy.CONCLUSION NVS is suitable for use as a quick screening test for limited literacy in primary health care settings.
