This study used eye-tracking technology to explore how individuals with different levels of health literacy visualize health-related information. The authors recruited 25 university administrative staff (more likely to have adequate health literacy skills) and 25 adults enrolled in an adult literacy program (more likely to have limited health literacy skills). The authors administered the Newest Vital Sign (NVS) health literacy assessment to each participant. The assessment involves having individuals answer questions about a nutrition label while viewing the label. The authors used computerized eye-tracking technology to measure the amount of time each participant spent fixing their view at nutrition label information that was relevant to the questions being asked and the amount of time they spent viewing nonrelevant information. Results showed that lower NVS scores were significantly associated with more time spent on information not relevant for answering the NVS items. This finding suggests that efforts to improve health literacy measurement should include the ability to differentiate not just between individuals who have difficulty interpreting and using health information, but also between those who have difficulty finding relevant information. In addition, this finding suggests that health education material should minimize the inclusion of nonrelevant information.
本研究使用眼动追踪技术来探索不同健康素养水平的个体如何可视化与健康相关的信息。作者招募了 25 名大学行政人员（更有可能具备足够的健康素养技能）和 25 名参加成人扫盲计划的成年人（更有可能具备有限的健康素养技能）。作者对每位参与者进行了最新生命体征（NVS）健康素养评估。该评估包括让个体回答有关营养标签的问题，同时观看标签。作者使用计算机化眼动追踪技术来测量每位参与者在与正在提出的问题相关的营养标签信息上花费的固定观看时间，以及他们花费在非相关信息上的时间。结果表明，NVS 得分较低与花费在与回答 NVS 项目不相关的信息上的时间显著相关。这一发现表明，提高健康素养测量的努力应该不仅包括区分那些难以理解和使用健康信息的个体，还应该包括那些难以找到相关信息的个体。此外，这一发现表明，健康教育材料应尽量减少不相关信息的纳入。
