摘　　要：健康网站是用户获取健康信息的重要来源,在线健康信息的质量关系到患者、医生、网站运营商等所有相关者的利益。网站页面元素是在线健康信息的载体,用户对信息质量的评价依赖于对页面元素的感知。本研究基于在线健康信息质量评价原则划分页面元素,采集和分析相关页面元素上的注意力分配;利用调查问卷收集质量评价数据,分析质量评价与页面元素注意力分配的相关性;通过凝视提示回顾式发声思考和半结构化访谈获取用户的主观感受,以解释质量评价与页面元素注意力分配之间的关系。研究结果发现,相比于其他页面元素,用户在医生认证资质和广告上的注意力分配较多;用户对健康信息权威性、保密性、公开性和广告政策的评价分别与相应页面元素的注视次数和注视时间正相关,对补充性和归因性的评价分别与相应页面元素的注视次数和注视时间负相关,而对合理性和透明性的评价与相应页面元素的注视次数和注视时间不相关;最后,从用户主观感受的角度揭示了注意力分配和质量评价产生关系的内在原因。本研究丰富了在线健康信息质量评价理论基础和研究方法,研究结论为改善在线健康信息内容质量和健康网站界面设计提供了参考。Health websites are an important source for those seeking to obtain health information,and the quality of online health information depends on the interests of patients,doctors,website operators,and other stakeholders.Users’evalua-tion of the quality of online health information depends on their perception of the elements of the pages carrying it.Based on the principles of quality evaluation of online health information,in this study,the page elements were divided,and data on the allocation of attention to each page element were collected and analyzed.A questionnaire was used to collect quality evaluation data,and the relationship between quality evaluation and the attention allocated to the page elements was ex-plored.To explain this relationship,data regarding users’subjective feelings were obtained through gaze-cued retrospec-tive think-aloud and semi-structured interviews.The results of this study indicate that,compared with the findings regard-ing other page elements,the users had a relatively high fixation count and spent a relatively long periods examining doc-tors’qualifications and advertisements.Evaluations of authority,privacy,financial disclosure,and advertising policies were positively correlated with the fixation count and duration on the corresponding page elements,while evaluations of complementarity and attribution were negatively correlated with the fixation count and duration on the corresponding page elements,and evaluations of justifiability and transparency were not correlated with a user’s fixation count and duration on the corresponding page elements.The internal reasons for the relationships are revealed in the study from the perspec-tive of users’subjective feelings.This study enriches the theoretical basis of,and research methods used for,evaluating the quality of online health information and provides suggestions for improving the quality of health-related informative con-tent and interface design of health websites.
