摘　　要：[目的/意义]探究多元属性任务情境下用户网络健康信息源选择偏好规律,可为健康信息行为研究提供更多洞见,也是对用户健康心理、健康行为与决策等问题的关切,可促进健康信息系统个性化、智能化服务的优化设计,进而帮助用户高效获取健康信息、解决健康问题、提高生活质量,助力“健康中国2030”的实现。[方法/过程]采用实验研究方法和模拟仿真工作任务情境,招募64名参与者参与实验,通过卡方检验和对应分析法分析实验数据,揭示了多元属性任务情境下用户网络健康信息源选择偏好特征。[结果/结论]在线问答社区、在线健康社区、社交媒体、百科类、专业数据库等排名前5的信息源构成用户网络健康信息的主要来源,这些平台应成为网络健康信息综合治理的聚焦对象;由任务复杂度、任务产出类型、健康话题等分面属性组合而成的任务类型对用户网络健康信息源的偏好有显著影响,即用户在进行不同类型健康任务的信息搜索时,对不同信息源的偏好不同;基于多元属性任务类型与信息源类型的对应关系,构建面向智能化健康信息系统个性化设计的任务类型—网络健康信息源选择偏好模型。[Purpose/Significant]It is important to explore the preference of users'online health information selection in the context of multi-attribute tasks to understand user's health psychology,health behavior and decision-making,and to provide more insights for the health information behavior.This study can promote the personalized and intelligent service design of health information system,and help users efficiently obtain health information,solve health problem and improve life quality,and contribute to the implementation of national strategy of"Healthy China 2030".[Method/Process]The study recruited 64 participants in the experiment.Through Chi-square test and correspondence analysis of experimental and simulated data,it demonstrated the characteristics of users'online health information selection preference in the multi-attribute task.[Result/Conclusion](1)Users mostly select the top 5 information sources,including online question&answer community,online health community,social media,encyclopedia and professional database.These health information platforms/sources should be the focus of comprehensive management.(2)The strength of correlation between the task types,which combined with different attributes,including task complexity,product and health topic,and different online health information sources are significantly different.Users have different preferences for different information sources with different task.(3)Based on the relationships between task types and information sources,a task type-online health information source selection preference model is developed for optimizing the design of health information system.
