This pilot study explores the impact of a health topics overview (HTO) on reading comprehension. The HTO is generated automatically based on the presence of Unified Medical Language System terms. In a controlled setting, we presented health texts and posed 15 questions for each. We compared performance with and without the HTO. The answers were available in the text, but not always in the HTO. Our study (n=48) showed that consumers with low health literacy or high stress performed poorly when the HTO was available without linking directly to the answer. They performed better with direct links in the HTO or when the HTO was not available at all. Consumers with high health literacy or low stress performed better regardless of the availability of the HTO. Our data suggests that vulnerable consumers relied solely on the HTO when it was available and were misled when it did not provide the answer.
本试点研究探讨了健康主题概述 (HTO) 对阅读理解的影响。HTO 是根据统一医学语言系统术语的存在自动生成的。在受控环境中，我们呈现了健康文本并针对每篇文本提出了 15 个问题。我们比较了有和没有 HTO 的表现。答案在文本中，但不一定在 HTO 中。我们的研究（n=48）表明，健康素养低或压力大的消费者在没有直接链接到答案的情况下，即使有 HTO 也表现不佳。当 HTO 中直接提供链接或根本没有 HTO 时，他们的表现会更好。健康素养高或压力小的消费者无论 HTO 是否可用，表现都更好。我们的数据表明，弱势消费者仅在 HTO 可用时依赖它，而当 HTO 未提供答案时则会被误导。
