差异性任务情境下用户移动诊疗信息搜索行为分析——一项实验研究
|
摘要
[目的/意义]探究差异性任务情境对用户移动诊疗信息搜索行为的影响,并基于对比分析为移动诊疗信息的产品和服务创新提供改进方法和策略。[方法/过程]选取事实型、解释型和探索型3种代表性任务情境,采用"情境实验+问卷访谈"的方法获取研究样本的行为特征数据并辅助以录屏软件全程记录实验过程,通过人工编码、数据清洗和数据预处理等步骤对收集到的问卷文本和视频数据进行处理,获得36个有效样本和108份有效数据并利用SPSS22. 0进行Mann-Whitney非参数检验。[结果 /结论]差异性任务情境对搜索过程变量均具有显著影响。相对于事实型任务,解释型任务和探索型任务不仅在查询串修改次数、访问网页数和点击链接数上显著更多,而且在搜索策略上也倾向于使用更多的搜索渠道。任务类型对用户在任务完成前后的感知任务难度、感知完成度和客观完成度等指标上有显著影响,其中事实型任务难度最低且客观完成度最高,任务类型对用户的任务认知和感知多渠道搜索有用性无显著影响。
[Purpose/Significance] This study aimed to explore the impact of different task situations on users' mobile medical information search behavior,and provide improved methods and strategies for product and service innovation of mobile medical information based on comparative analysis. [Method/Process] Factual task,explanatory task and exploratory task were selected as three most representative task situations. "situation experiment+questionnaire interview" was adopted to obtain behavioral characteristics data of the research samples and the experimental process was recorded through the screen recording software. The collected questionnaire text and video data were processed through manual coding,data cleaning and data preprocessing,and 36 valid samples and 108 valid data were obtained and Mann-Whitney nonparametric test was performed using SPSS22. 0. [Result/Conclusion] Different task situations had a significant effect on search process variables. Compared with factual tasks,explanatory tasks and exploratory tasks not only significantly increased the number of query string modifications,the number of visited pages and the number of click links,but also tended to use more search channels in search strategies; Task type had significant influence on perceived task difficulty before and after experiment,perceived task completion degree and objective task completion degree. Among them the factual task was the least difficult and the objective completion degree was the highest. However,task type had no significant effect on task cognition and perceived usefulness of multichannel search.
