【摘要】 本研究聚焦于用户网络健康信息搜索过程中的交互感知、交互行为及其交互质量，采用实验方法，基于8项模拟仿真工作任务，对招募的64名实验参与者的健康信息搜索过程进行观察和记录，并基于相关性分析和Stepwise多元线性回归分析，对交互感知与交互质量、交互行为与交互质量间的关系进行探究。研究结果表明，用户网络健康信息搜索时的信息交互感知、任务交互感知与交互质量显著相关，且交互感知在一定程度上影响了交互质量，而感知交互绩效与交互质量相关性不显著；用户网络健康信息搜索中的系统交互行为、内容交互行为与交互质量显著相关，且交互行为可成为有效表征或预测用户网络健康信息交互质量的信号指标。本研究揭示了交互感知对交互质量的影响作用，探究了交互行为对交互质量的表征或预测价值，深化了对用户健康信息搜索行为或过程的认知，为智能化健康信息检索与服务的优化设计提供了支持。更多还原

【Abstract】 This study focused on interaction perception, behavior, and quality during users’ online health information searches. We conducted an experiment involving eight simulated work task situations in which we observed 64 participants and recorded when they searched for health information. We performed correlation and stepwise multiple linear regression analyses to analyze the relationships among interaction perception and quality as well as between interactive behavior and interaction quality. The results indicated that users’ information-interaction and task-interaction perceptions during online health information searches were significantly correlated with interaction quality. We also found that interaction perception, to some extent, impacted interaction quality. However, the correlation between perceived interaction performance and quality was not significant. Additionally, system-and content-interactive behaviors were significantly correlated with interaction quality, and we identified interactive behavior as an effective indicator for characterizing or predicting users’ online health information interaction quality. The findings reveal the influence of interaction perception on interaction quality, and suggest the indication or predictive value of interactive behavior on interaction quality. The results help us understand users’ health information searching behavior and processes better and have implications for improving the design of intelligent health information retrieval and services.更多还原
