How to Improve the Credibility and Interestingness of Social Media Healthcare Information?

Social media is a widely accepted medium for interaction and communication. A large amount of information about health care springs out through various social medias. We Chat is a multi-function social media as well as an information sharing platform with largest users in China right now. Many We Chat accounts concentrated on showing and spreading healthcare information. They are trying to attract more readers and spread the information among them. Thus ， it is important to find out what changes people ’ s behavior or attitude toward certain kind of information. This research focuses on the influence of the authority of information sources and authors as well as the format and length of information. Those four factors, compared with those in the formal studies are much more specific and much easier to be quantization especially for measurement. Lab experiment study was applied in this paper. The result comes that the authority of subscriptions and information format affect both perceived credibility and interestingness levels, while the authority of authors only makes difference to credibility level. And the length of information shows no significant influence

Trust of Information on Social Media: An Elaboration Likelihood Model

Social media such as Twitter and Facebook are increasingly being used as a source of information in critical situations such as natural disasters and civil unrests. However, false information exists on social media and trusting false information not only leads users to make wrong decisions but can also have dire impact on the society. This research-in-progress examines how individuals process information on social media to determine whether or not to trust the information. Based on the elaboration likelihood model, a research model elucidating the effects of information quality, source credibility, and majority influence on users’ trust of information on social media is proposed. Further, the moderating effects of personal involvement and users’ prior knowledge are investigated. Results from a pilot survey indicate that majority influence has a stronger effect on trust than source credibility for social media users and they are likely to rely on information quality as well as source credibility and majority influence when their personal involvement is high

Website quality: An analysis of scientific production

A range of different methods and tools have been proposed by both academics and professionals in recent years for evaluating the quality of websites. Some are of general application and can be used to assess any type of website, while others have been adapted to the specialized characteristics of the websites employed in a given sector. This paper undertakes an analysis of existing scientific production in this field, with the aim of identifying its most relevant publications, its principal authors and the specific sectors served by the sites under evaluation. By triangulating review methods, 716 texts, published between 2000 and 2018, were identified in Scopus, Web of Science and other databases and examined. In addition to basic bibliographic information, the number of citations received by each text was recorded using Google Scholar. The area of knowledge in which each author works was also categorized based on his or her specific affiliations. The results point to a growing interest in website quality in a scientific community that has a presence in more than 70 countries. Its authors are drawn from various disciplines, although the highest number of publications is recorded in computer science, business and medical informatics. The most frequently cited texts are in fact seminal books in the associated disciplines of usability, information architecture and user experience. However, as of 2007, the number of texts describing evaluation tools for the websites of specific sectors – most notably, education (33%), health (27%) and commerce (21%) – increased their share. In conclusion, it is evident that website quality is a field of study undergoing constant growth and increasing specialization and one that offers ample opportunities for research

Toward a Typology of Health 2.0 Collaboration Platforms and Websites

During the past decade, the proliferation of social media has infiltrated various sectors of social and business communications. Of particular interest is the growth of health related websites and the healthcare sector’s adoption of social media. In this paper, we develop a typology of health 2.0 collaboration platforms and websites. According to the proposed typology, two major types of actors within health 2.0 websites are health professionals (P) and health consumers (C). Each type of user can serve as either support provider or support recipient. Thus, we define the main types of health 2.0 platforms and websites as professional-to-professional (P2P), professional-to-consumer (P2C), consumer-to-consumer (C2C), and consumer-to-professional (C2P). We describe each type and utilize the typology to investigate 16 popular health 2.0 websites and the collaboration platforms they provide. Our typology can be used as a basis for the future research on health social media

An Experimental Investigation into Promoting Mental Health Service Use on Social Media: Effects of Source and Comments

Mental health is an increasingly prevalent topic of public interest, but remains a complex area requiring focused research that must account for negative perceptions surrounding mental health issues. The current work explores the roles of social media information source credibility and valence of social media comments on health outcomes in such a mental health context. We used a 2 (message source: professional vs. layperson) × 3 (valence of comments: positive vs. negative vs. mixed) online experiment to examine the effects of source and valence of comments on trust, attitudes and intentions related to mental health information and services among 422 undergraduate students. Results supported the hypothesized model in which source influenced cognitive trust while comments influenced affective trust. Cognitive and affective trust both impacted attitudes towards mental health information which encourages the intention to share such information on social media. Additionally, affective trust impacted attitudes towards mental services which influenced intentions to seek them out. Source and valence of comments on social media impact different behavioral intentions regarding the use of mental health services. This study provides insights for future social media campaigns promoting mental health service use

Foul Ball: Audience-Held Stereotypes of Baseball Players

This study experimentally tested whether participants held and/or applied stereotypes of baseball players. Participants were asked to rate white, black, and Latino baseball players based on stereotypes consistently identified in previous literature. Participants saw a photo of a player and an anonymous paragraph from a newspaper that highlighted a particular stereotype. They were then asked to rate the author\u27s credibility. Black players were rated as higher in physical strength and natural ability, consistent with previous literature concerning how athletes were described. However, white and Latin players were not stereotyped. But participants rated white-consistent descriptions as credible and Latin-consistent descriptions as less credible. These results are interpreted through the prism of social identity theory

A Black and White Game: Racial Stereotypes in Baseball

The current study experimentally tested stereotypes and credibility of messages associated with athletes. Participants were asked to rate photos of black and white baseball players based on stereotypes identified in previous literature. They were then given an anonymous paragraph from a newspaper that featured either a stereotype consistent or inconsistent message and asked to rate the author\u27s credibility. Black players were rated significantly higher in physical strength and natural ability, which is consistent with previous literature. However, inconsistent with previous literature, white players were not rated significantly higher in intelligence and leadership. Despite these results, when measuring credibility, this study found white-consistent stereotypes to be credible, whereas black-consistent ones were not. These results are interpreted in light of Devine\u27s model of stereotype processing and in-group, out-group bias

A Revised Model of Trust in Internet-Based Health Information and Advice: Cross-Sectional Questionnaire Study

Background: The internet continues to offer new forms of support for health decision making. Government, charity, and commercial websites increasingly offer a platform for shared personal health experiences, and these are just some of the opportunities that have arisen in a largely unregulated arena. Understanding how people trust and act on this information has always been an important issue and remains so, particularly as the design practices of health websites continue to evolve and raise further concerns regarding their trustworthiness.Objective: The aim of this study was to identify the key factors influencing US and UK citizens’ trust and intention to act on advice found on health websites and to understand the role of patient experiences.Methods: A total of 1123 users took part in an online survey (625 from the United States and 498 from the United Kingdom). They were asked to recall their previous visit to a health website. The online survey consisted of an updated general Web trust questionnaire to account for personal experiences plus questions assessing key factors associated with trust in health websites (information corroboration and coping perception) and intention to act. We performed principal component analysis (PCA), then explored the relationship between the factor structure and outcomes by testing the fit to the sampled data using structural equation modeling (SEM). We also explored the model fit across US and UK populations.Results: PCA of the general Web trust questionnaire revealed 4 trust factors: (1) personal experiences, (2) credibility and impartiality, (3) privacy, and (4) familiarity. In the final SEM model, trust was found to have a significant direct effect on intention to act (beta=.59; P<.001), and of the trust factors, only credibility and impartiality had a significant direct effect on trust (beta=.79; P<.001). The impact of personal experiences on trust was mediated through information corroboration (beta=.06; P=.04). Variables specific to electronic health (eHealth; information corroboration and coping) were found to substantially improve the model fit, and differences in information corroboration were found between US and UK samples. The final model accounting for all factors achieved a good fit (goodness-of-fit index [0.95], adjusted goodness-of-fit index [0.93], root mean square error of approximation [0.50], and comparative fit index [0.98]) and explained 65% of the variance in trust and 41% of the variance in intention to act.Conclusions: Credibility and impartiality continue to be key predictors of trust in eHealth websites. Websites with patient experiences can positively influence trust but only if users first corroborate the information through other sources. The need for corroboration was weaker in the United Kingdom, where website familiarity reduced the need to check information elsewhere. These findings are discussed in relation to existing trust models, patient experiences, and health literacy

Facebook: How Likes and Followers Affect Users Perception and Leadership

The online social network, Facebook, creates a problem in which likes , and followers give a user the appearance of leadership. The accumulation of likes in the online social network environment, such as Facebook, might offer non-legitimate leader status, similar to campaign donations contributing to the appeal of a political candidate. This appearance of Facebook popularity through likes possibly skews the other members\u27 perspective regarding a user\u27s leadership competence. The user often looks official, popular, and influential through the advent of likes and followers. Any opinions of a user with accumulated likes could be taken with greater weight than a user with significantly fewer likes and followers. The objective of this study finds if the accumulation of likes and followers on Facebook leads to perceived user leadership status. The data includes a Facebook user questionnaire survey and subsequent data analysis. This qualitative study may provide a useful expansion of our traditional definition of leadership. The expansion could enhance academic and leadership studies courses with a greater understanding of online social capital

Online Health Information Seeking and Adolescents’ Intention Towards Health Self-Management

The widespread availability of healthcare websites has changed the traditional healthcare system by enabling patients to play an active role in health management. The emerging field of Health 2.0 has enabled both professionals and patients to engage in content generation; changing the traditionally accepted professional healthcare to a new dimension of patient-centric healthcare. With the easy access to health information online, patients are turning to the Internet to look up for symptoms, diagnose health problems, or determine treatment procedures. Anecdotal evidence suggests that individuals’ health management practices can be highly influenced by online health information. Considering the psychological characteristics of adolescents and their high exposure to the Internet, this study investigates the mechanisms of how online health information can motivate adolescents’ behavioral intention towards self-management of their health issues. Our results showed that empowerment, attitude towards the website and privacy concerns significantly predict adolescents’ health self-management behavior. Our findings also revealed that perceived health threat is not directly influencing the intention to self-managed health but instead interacts with other factors to influence intention. The findings provide important implications for theory and practice, by providing a better understanding of an emerging field of health care
