中文摘要:
      伴随着Web 2.0时代网络健康信息体量的激增,人们普遍对互联网环境下健康信息质量产生忧虑,其主要原因是大量失真健康信息存在于互联网中,对信息接受者主观感知造成误导,并对消费者的健康知情决策带来潜在威胁。消费者在失真健康信息误导下所作出的健康决策可能会引发严重的健康后果,因此理解消费者对网络失真健康信息可信度判断的相关影响因素,对公民健康教育与全民健康促进都将具有积极意义。本文通过系统的文献回顾,分别从信息特征与个体特征视角归纳出消费者对失真健康信息可信度判断的若干影响因素,并提出相应研究问题。研究采用问卷调查法探索各研究问题,问卷设计利用信息话题与信息表征框架两个维度,选取八则失真健康信息作为问卷阅读素材,在对健康素养的测量上借鉴并汉化了国际通用的最新关键指标。研究结果发现:在信息特征方面,失真信息的表征框架与信息话题对消费者可信度判断有显著影响,且二者存在交互效应;在个体特征方面,年龄、性别、健康素养等因素对消费者失真信息可信度判断具有显著影响。图1。 表4。 参考文献61。
英文摘要:
Health information seeking has a long history in human history. Health information empowers consumers to make informed health decisions and plays significant roles in many health activities such as consumers self diagnose, chronic disease management, and patient physician communications. The effectiveness of such empowerment is based on one common assumption, namely the information quality. The accurate information could foster consumer's informed health decisions, while distorted information could lead to severe health crises.
However, in the Web 2.0 era, the quality of online health information is generally problematic. There is considerable health misinformation existing on the Internet. First, this paper defines the term health misinformation from a terminology perspective and distinguishes it from some close concepts such as health rumor or fake news. Further, we argue that the misleading effects of health misinformation result from the bias created in credibility judgment. Therefore, it is necessary to understand how the health misinformation influences consumer's credibility judgment so that the appropriate interventions could be designed.
Credibility can be regarded as an individual's perception of information quality. Because the concept of credibility address both objective information quality and individual's subjective perception, we posit that both the information features and individual characteristics might influence consumer's credibility judgment on health misinformation. Regarding information features, two specific research questions are raised to investigate how the message framing could impact credibility judgment and whether such effects are moderated by different health topics. In regards to individual characteristics, another two research questions are proposed to address the effects of demographics and health literacy respectively.
We manipulate 4 categories of stimuli with two kinds of message framing and two different health topics, each category containing 2 pieces of articles. This study measures several variables, including credibility, health literacy, demographics, perceived relevance, perceived importance, etc. The measurement of health literacy is based on the Chinese version of the Newest Vital Sign. The cross cultural adaption of the instruments is conducted, and reliability is examined. By the open online recruitment, we get 252 valid respondents, total 2,016 records of credibility evaluation observations.
The multiple regressions are employed in data analysis. The results suggested that the various ways of message framing and different health topics could impact consumer's credibility perception significantly. Moreover, there are significant interaction effects between message framing and health topic. The demographic factors and health literacy are also significant predictors for credibility perception in health misinformation context. Based on the discussion, we propose several practical implications for misinformation intervention and health promotion. 1 fig. 4 tabs. 61 refs.
