健康素养在研究人员、临床医生、患者和决策者中的重要性大大增加。需要更好的工具和衡量战略。本研究的目的是利用现代健康信息技术和现代心理测量学，开发一种新的健康素养量表。我们设计的健康LiTT作为一个自我管理的多媒体触摸屏测试的基础上项目反应理论（IRT）的原则。我们招募了619名讲英语的初级保健患者在诊所为服务不足的患者。我们测试了三种项目类型（散文，文档，定量），它们可以很好地结合在一起，可靠地测量健康素养的单一维度。Health LiTT评分符合心理测量标准（可靠性为0.90或更高），用于测量低至中等范围的个体受访者。平均健康LiTT评分与年龄、种族/民族、教育、收入和先前的计算机使用相关（p<0.05）。我们创建了一个包含82个项目的IRT校准项目库。需要进行标准设置，以将项目分类并映射到结构上，并确定测量差距。我们正在将Health LiTT纳入现有的在线研究管理工具。这将使Health LiTT管理在用于其他患者报告结果的同一触摸屏上，以及实时评分和健康素养评分报告。
The importance of health literacy has grown considerably among researchers, clinicians, patients and policymakers. Better instruments and measurement strategies are needed. Our objective was to develop a new health literacy instrument using novel health information technology and modern psychometrics. We designed Health LiTT as a self-administered multimedia touchscreen test based on item response theory (IRT) principles. We enrolled a diverse group of 619 English-speaking primary care patients in clinics for underserved patients. We tested three item types (prose, document, quantitative) that worked well together to reliably measure a single dimension of health literacy. The Health LiTT score meets psychometric standards (reliability of 0.90 or higher) for measurement of individual respondents in the low to middle range. Mean Health LiTT scores were associated with age, race/ethnicity, education, income and prior computer use (p<0.05). We created an IRT-calibrated item bank of 82 items. Standard setting needs to be performed to classify and map items onto the construct and to identify measurement gaps. We are incorporating Health LiTT into an existing online research management tool. This will enable administration of Health LiTT on the same touchscreen used for other patient-reported outcomes, as well as real-time scoring and reporting of health literacy scores.
