Abstract

Through "health risk calculator" websites, Internet users can obtain personalized and interactive predictions about health risks. While it seems appropriate to provide laypersons with educational health information, prior research emphasizes the importance of understanding behavioral responses when communicating risk information. In order to systematically explore and analyze these relationships in the context of online health information, a new diabetes risk calculator website was developed to serve as an intervention in which the presence of personalization and interactive feedback could be manipulated for randomized experimentation. The website was integrated with pre- and post-intervention surveys in order to assess users in terms of information usage and risk perceptions. In two preliminary experiments, there was a small, unexpected negative impact of personalization on multiple measures of information usage. The implications of these results are discussed in the context of improving the presentation of online risk information for practical and experimental evaluation purposes.

基于web的健康风险计算器的设计、实现和初步评估

通过“健康风险计算器”网站，互联网用户可以获得个性化、互动式的健康风险预测。虽然向外行人提供教育健康信息似乎是合适的，但先前的研究强调了在传达风险信息时理解行为反应的重要性。为了在在线健康信息的背景下系统地探索和分析这些关系，我们开发了一个新的糖尿病风险计算器网站，作为一种干预手段，其中个性化和交互式反馈的存在可以被操纵进行随机实验。该网站与干预前和干预后的调查相结合，以评估用户在信息使用和风险认知方面的情况。在两个初步实验中，个性化对信息使用的多个衡量标准产生了意想不到的小负面影响。这些结果的含义在改进在线风险信息的实际和实验评估目的的背景下进行了讨论。
