Consumer health information seeking in social media: a literature review

Objective

The objective of this literature review was to summarise current research regarding how consumers seek health‐related information from social media. Primarily, we hope to reveal characteristics of existing studies investigating the health topics that consumers have discussed in social media, ascertaining the roles social media have played in consumers’ information‐seeking processes and discussing the potential benefits and concerns of accessing consumer health information in social media.

Methods

The Web of Science Core Collection database was searched for existing literature on consumer health information seeking in social media. The search returned 214 articles, of which 21 met the eligibility criteria following review of full‐text documents.

Conclusion

Between 2011 and 2016, twenty‐one studies published explored various topics related to consumer information seeking in social media. These ranged from online discussions on specific diseases (e.g. diabetes) to public health concerns (e.g. pesticide residues). Consumers’ information needs vary depending on the health issues of interest. Benefits of health seeking on social media, in addition to filling a need for health information, include the social and emotional support health consumers gain from peer‐to‐peer interactions. These benefits, however, are tempered by concerns of information quality and authority and lead to decreased consumer engagement.     

The Role of Engagement in Learning From Active and Incidental News Exposure on Social Media

The growing reliance on social media as news platforms may lead to more passive news consumption but also offers greater potential for engaging in news. This study investigates the role of engagement with news content on Facebook and Twitter between news exposure and current events knowledge. An online survey (N = 400) tests the relationships between social media news seeking, incidental exposure to news on social media, engagement in shared news content, cognitive elaboration, and current events knowledge. The results show that both active seeking of and incidental exposure to news on both sites are linked to engagement, which is linked to greater cognitive elaboration about the content. Furthermore, engagement mediates the relationship between both types of news exposure and cognitive elaboration. However, engagement and elaboration are not related to knowledge. These results indicate that the key role of social media in news content is not knowledge gain but the ability to engage users who may be passively receiving news on these sites. This study extends the cognitive mediation model of learning from the news in the context of current social media, with updated news consumption norms such as engagement with news on these sites, and incidental news exposure.     

Trust,norms and networks in social media environmental mobilization: a social capital analysis of Under the Dome in China

After the Spring Festival of 2015, an environmental documentary called Under the Dome in which Chai Jing acted as a narrator has caused the public opinion to boom in social media in China. Why could a documentary released by internet attract so much attention and spark such a heated discussion? What are the factors that have influence on the information dissemination of social media environmental mobilization? This paper employed case study and semi-structure interviews to reveal these questions. It turned out that individual trust, group norms and information networks of the social capital played an important role in the social media environmental mobilization. The reason why Under the Dome became a hot issue was that it made full use of the social media users’ trust on the mobilizer, aroused the mobilized’s emotions and combined the network channels of social relationships.

The impact of online social capital on social trust and risk perception

This study investigated how social media use and online social capital might have influenced social trust and risk perception of a public health crisis in China. It also tested the validity and reliability of the online social capital measurement in the context of a Chinese food-safety crisis. Study findings validated the impact of online social capital on social trust and risk perception. In addition, two new dimensions of online social capital scale were identified; these two dimensions are in parallel to Putnam’s [2000. Bowling alone: The collapse and revival of american community. New York: Simon and Schuster] conception of ‘bonding social capital’ and ‘bridging social capital.’ Social and policy implications of the study results are discussed.     

When is Fiction as Good as Fact? Comparing the Influence of Documentary and Historical Reenactment Films on Engagement,Affect, Issue Interest,and Learning

This study advances documentary film effects research by comparing the influence of a political documentary with a historical reenactment film on narrative engagement, affect, learning, and interest. Using the Rwandan genocide as a context of study, a documentary film, The Triumph of Evil, and the historical reenactment fictional film, Hotel Rwanda, were examined. Results revealed significant differences between documentary and historical reenactment film exposure for affective responses and issue knowledge gain. However, increased issue interest and narrative engagement were not significantly different for the two stimulus groups, suggesting that dramatic fictional reenactments of socio-political events lead to increased issue interest as much or more than the live footage and factual account of events offered in a documentary. The results of this study are discussed in terms of their importance for key democratic outcome variables (e.g., knowledge and participation), along with suggestions for future documentary film research.     

Global risk,domestic framing: coverage of the North Korean nuclear test by US,Chinese, and South Korean news agencies

Comparative framing analysis on coverage of the North Korean nuclear test in the US Associated Press, Chinese Xinhua, and South Korean Yonhap news agencies identified four major media packages. First, a common ‘threat’ frame dominated coverage by all news agencies, represented by reconfiguration of geopolitics and an emphasis on global cooperation in both perception and resolution of the nuclear test. Second, with each nation positioning itself differently in the world power system, the issue was notably domesticated in the news, with Associated Press connecting the nuclear test to the broader ‘War on Terror’ framework found frequently in US media, Xinhua promoting a negotiation principle in handling the issue, and Yonhap framing the test with a ‘Cold War’ perspective. In all three cases, national political interests exerted important impacts on the construction of frames. The compatibility of the seemingly opposite packages (globalizing vs. domesticating) signifies both intensification of worldwide social relations and reassertion of national stands. This finding lends support to the transformationalist view of globalization, which suggests that the nation state still matters in a globalized world, but is being recontextualized in a more complex world of politics and culture.     

Silent Majority: Childhood Vaccinations and Antecedents to Communicative Action

The topic of childhood vaccinations has received much news media attention recently, prompting scholars to examine how the public has responded. In light of this news, and the deep divide that seems to exist between parents who support childhood vaccinations and those who do not, this study examines how and why individuals may involve themselves in communication about vaccinations, particularly on social media or in other online environments. Focusing on the concept of communicative action and drawing from spiral of silence and other research, a survey of mothers (N = 455) found that those who do not support childhood vaccinations are more likely to engage in communication about the issue, including information seeking, attending, forefending, permitting, forwarding, and sharing. In addition, issue importance and affective and cognitive involvement help drive communicative action regarding childhood vaccinations, which could affect public opinion or public perceptions of the issue. Theoretical and practical implications are discussed.     

Communication message cues and opinions about people with depression: an investigation of discussion on Weibo

A content analysis was conducted of the posts generated by mass media organizations and public opinion leaders on the Chinese social media platform Sina Weibo to investigate the associations between several communication message cues and opinions about people with depression (N = 102). The study revealed that the posts of the influential users were more likely to be stigmatizing when they communicated stereotypes, but less likely to be stigmatizing or more likely to be supportive when they made personal, genetic and medical, and social and environmental cause and responsibility claims. The posts were also more likely to be supportive if the influential users presented treatment and recovery information. In addition to finding out what communication cues activate the influential users' stigmatizing or supportive opinions, the study also examined and found the impact of the influential users' opinions on their followers' opinions on this issue (N = 8261). The findings showed that the public opinion leaders were more likely than the mass media to express support for people with depression. This support then translated into supportive responses among their followers toward those living with the disease.     

Health answer quality evaluation by librarians,nurses, and users in social Q&A

Health information consumers and patients increasingly take an active role in seeking health information online and in sharing their health problems and concerns in online support groups and social media venues. However, they may risk being influenced by unreliable and misleading information in such environments, as no intermediaries monitor the quality of this information. This study focuses on evaluating the quality of health information exchanged in one of the social media venues, by investigating how librarians, nurses, and users assessed the quality of health answers in Yahoo! Answers, a social question-and-answering (Q&A) service. Through statistical analysis differences among the three participant groups, how the background characteristics influenced their assessments, and the relationships between characteristics of the content of answers and quality evaluation criteria were each considered in detail. Librarians and nurses shared similar ratings of answer quality, but had differences in their level of medical knowledge and the types of services they offer, resulting in minor differences across criteria. Users perceived the quality of health answers in social Q&A to be higher than librarians and nurses for almost all criteria. Depending on the sources of information presented in health answers, librarians, nurses, and users gave different quality assessments. Implications exist for research into and practice of evaluating the quality of health information, which need to address both search and domain expertise along with the sharing of socioemotional values preferred by users.

The relationships between university students' information-seeking strategies,social-media specific epistemological beliefs,information literacy,and personality traits

Due to doubts about the reliability of information in social media environments, and the epistemological beliefs of individuals who use these media, questioning the source of information and the perception of knowledge structure, is an important research topic. A structural model was constructed to explore structures associated with epistemological beliefs (justification for knowing) and online information-seeking strategies. The model included personality traits and information literacy. Data were collected from 190 university students. PLS-SEM was implemented in the analysis of the data. Analysis revealed that there was a significant relationship between epistemological beliefs specific to social media and information-seeking strategies, and information literacy structure has a direct effect on information-seeking strategies. Agreeableness and neuroticism were related with several dimensions of social media-specific beliefs. It was found that the personality trait which has the greatest effect on online information-seeking strategies is conscientiousness.     

Examining cultural identity and media use as predictors of intentions to seek mental health information among Chinese

Mental health is a stigmatized issue in many parts of the world. We conducted a survey of Chinese adults (n?=?661) to examine predictors of intentions to seek information related to mental health. Attitudes and subjective norms positively influenced intentions to seek mental health information, with subjective norms being a stronger predictor. Cultural identity was negatively associated with intentions to seek mental health information, with participants who held a stronger cultural identity being less likely to seek information related to mental health. Media use was positively associated with intentions to seek information. This research highlights that cultural identity may influence mental health information seeking, and that health campaigns could focus more on influencing subjective norms, thereby changing the seeking intention of Chinese adults regarding mental health information. Additionally, practitioners may want to explore possible ways of providing health information to people with strong cultural identity, as they may be less likely to seek out information on their own.     

eHealth literacy and the motivators for HPV prevention among young adults in Kenya

ABSTRACT

The human papillomavirus (HPV) is one of the most common but preventable sexually transmitted infections that affect males and females but knowledge about it and vaccine uptake remain low. As organizations adopt eHealth communication strategies to communicate about HPV, this study examines the association between eHealth literacy (and related elements) and the motivators for HPV prevention that are based on the protection motivation theory. A survey was conducted among 472 young adults in Kenya and results show moderate eHealth literacy (M = 3.21, SD = 1.03) and online information seeking (M = 3.57, SD = 1.08) but low HPV knowledge and risk perception. eHealth literacy was correlated with HPV knowledge, perceived risk, self-efficacy, and response efficacy whereas online health information seeking were correlated with perceived seriousness of HPV infection. This study suggests examining the discrepancy between online information seeking and knowledge and the disparities in eHealth literacy among young adults in HPV communication.     

社会力量参与图书馆建设制度保障研究

采用文献调研、案例研究和政策文本分析等方法,对我国社会力量参与图书馆建设的制度保障进行研究.我国当前社会力量参与图书馆建设活动按性质可分为三类:对政府办图书馆事业的捐赠和支持活动;公益性和半公益性图书馆举办;营利性和非营利性图书馆举办.国内现有图书馆法规对社会力量办馆规定较为笼统,没有区分上述不同性质活动.从国外立法经验看,规范对象多为公益性图书馆,很少涉及营利性、非营利性图书馆.据此,本研究对公共图书馆立法提出一些原则建议.     

Media Dialogue: Perceiving and Addressing Community Problems

Scholars have long debated the role of media and discussion in encouraging tolerance and engagement in politics and community. Theories range from the dismissal of effects to the assertion of powerful influences, and from claims of "media malaise" to the promise of "virtuous circles." Of course, results from research exploring these issues vary by context and methods of study. Yet most past research is plagued by at least 1 of 2 methodological weaknesses: the difficulty of assessing causality in cross-sectional survey designs and/or of attributing the observed effects to information gains rather than to the deliberative process itself. Acknowledging these weaknesses, we rely on data from a quasi-experimental study examining a media dialogue effort. In this study, randomly selected public television members and partners were recruited into various forms of "real world" exposure and discussion about the documentary film Two Towns of Jasper. This documentary highlights the divisions in Jasper, Texas following the racial killing of James Byrd, Jr., who was dragged to his death behind a pickup truck by 3 White men. Controlling for a wide range of preexisting differences, including past political discussion and participation, we compared individuals who had different experiences of the intervention. Results reveal that media consumption was positively related with willingness to discuss the issue of race and participate politically around this issue. Above and beyond media consumption, participation in a heterogeneous citizen's forum that discussed the documentary contributed to awareness of racism, as well as increased willingness to further discuss and participate on this issue. This article highlights the importance of citizen dialogue in combination with media consumption for engagement, and suggests an alterative to forums such as citizen juries, study circles, and deliberative polls.

Improving Bhutan’s academic libraries,recommendations from a situational analysis

Abstract

This paper reports from a survey of media exposure and level of knowledge among senior high school students at various locations in Indonesia. Government budgets for education have recently been dramatically reduced in Indonesia and increasing financial burdens are put on the households, like in many other poor countries. There is a tendency to increasing differences in quality of schooling among social layers and geographical areas. Main conclusions in this research are that information asymmetry exists as a problem in society and that type of school and location matter more than media exposure for students’ knowledge level. Students in public schools generally score significantly higher than those in private institutions. Also, students’ level of knowledge tends to fall with decreasing level of geographical centrality. Our policy recommendations include increased public investment in quality schooling for all.     

Investing in knowledge? Information asymmetry and Indonesian schooling

This paper reports from a survey of media exposure and level of knowledge among senior high school students at various locations in Indonesia. Government budgets for education have recently been dramatically reduced in Indonesia and increasing financial burdens are put on the households, like in many other poor countries. There is a tendency to increasing differences in quality of schooling among social layers and geographical areas. Main conclusions in this research are that information asymmetry exists as a problem in society and that type of school and location matter more than media exposure for students’ knowledge level. Students in public schools generally score significantly higher than those in private institutions. Also, students’ level of knowledge tends to fall with decreasing level of geographical centrality. Our policy recommendations include increased public investment in quality schooling for all.
