摘要

[目的/意义] 揭示健康素养(较好/偏低)、AI信任度(偏高/较低)及任务类型(急性病/慢性病)对个体对话式健康信息搜索行为的驱动机制,为人智协同健康服务决策系统设计提供理论依据与实践启示。[方法/过程] 采用实验室实验法,招募72名被试执行健康信息搜索任务,通过Mann-Whitney U检验与Scheirer-Ray-Hare检验分析搜索行为指标差异,并提出驱动机制。[结果/结论] 在“平均查询长度”“提问轮次”等多个健康信息搜索行为指标上,健康素养、AI信任度及任务类型存在显著的主效应与交互效应。健康素养及AI信任度双高个体的“平均查询长度”最长,双低个体最短; AI信任度偏高个体在急性病任务中“提问轮次”显著高于慢性病任务; AI信任度较低个体在慢性病任务中的“后续寻求解释行为”“提问轮次”及“提问关联度”指标均明显高于急性病任务。

Abstract

[Purpose/Significance] To uncover the driving mechanisms of individual conversational health information search behavior by examining the roles of health literacy (higher vs. lower), AI trust (higher vs. lower), and task type (acute illness vs. chronic illness). The findings provide a theoretical basis and practical implications for the design of human-AI collaborative health service decision-making systems. [Method/Process] A laboratory experiment was conducted with 72 participants performing health information search tasks. Mann-Whitney U tests and Scheirer-Ray-Hare tests were employed to analyze differences in search behavior indicators and to propose the underlying driving mechanisms. [Result/Conclusion] Significant main effects and interaction effects of health literacy, AI trust, and task type were found across multiple conversational health information search behavior indicators such as “average query length” and “dialogue rounds”. Individuals with both high health literacy and high AI trust demonstrated the longest average query length, while those with low levels of both showed the shortest. Participants with higher AI trust engaged in significantly more dialogue rounds during acute illness tasks than in chronic illness tasks. In contrast, for individuals with lower AI trust, the “follow-up explanation-seeking behavior”, “dialogue rounds”, and “question relevance” in chronic illness tasks were significantly higher than those in acute illness tasks.
