Perceptions of Traditional Information Sources and Use of the World Wide Web to Seek Health Information: Findings From the Health Information National Trends Survey

As medical information becomes increasingly available and individuals take a more active role in managing their personal health, it is essential for scholars to better understand the general publics information-seeking behavior. The study reported here explores the use of the World Wide Web to seek health information in a contemporary information-media environment. Drawing from uses and gratifications theory and the comprehensive model of health information seeking, perceptions of traditional information sources (e.g., mass media, ones health care provider, etc.) are posited to predict use of the Web to seek health information and perceptions of information acquired from searches. Data from the Health Information National Trends Survey (HINTS; N = 3982) were analyzed to test study hypotheses. Trust in information-oriented media, entertainment-oriented media, and ones health care provider all predicted Web use behavior and perceptions. The implications of the findings for research on information seeking and the role of the Web in patient empowerment are discussed.

Health information-seeking and perceptions of website credibility: Examining Web-use orientation, message characteristics, and structural features of websites

The study reported here examined perceptions of health website credibility during the process of acquiring health information using the World Wide Web. The relationships between perceptions of website credibility and both message characteristics (e.g., statistics, testimonials) and structural features of health websites (e.g., privacy policy statement, third-party endorsements) were assessed. Additionally, ones Web-use orientation (i.e., searching or surfing) was evaluated as a moderator of the preceding relationships. The results showed a positive relationship between the presence of structural features and perceptions of website credibility as well as a positive relationship between the presence of message characteristics and attitudes about the health topic. Although Web-use orientation moderated the relationship between message characteristics and perceptions of website credibility, the nature of this relationship was inconsistent with study predictions.

The Impact of Anonymity on Perceptions of Source Credibility and Influence in Computer-Mediated Group Communication: A Test of Two Competing Hypotheses

As scholars and practitioners have endeavored to develop computer-based tools that foster effective communication and collaboration in groups, anonymity has played a key role. Anonymity purportedly minimizes status differences, liberates team members from a fear of retribution, and makes members feel more comfortable contributing to discussions. Yet these benefits may be outweighed by the impact of anonymity on receiver perceptions and behavior. Two competing hypotheses, drawn from adaptive structuration theory, were tested in this study to determine the impact of anonymity on receiver perceptions of sources and messages in computer-mediated group communication. The results of the multilevel models offer evidence in support of the discounting hypothesis and suggest that anonymity provided by electronic meeting systems may undermine source credibility and influence.

A Meta-Analysis of Research on Inoculation Theory

A meta-analysis of 54 cases testing the effectiveness of inoculation theory at conferring resistance and examining the mechanisms of the theory was conducted. The analyses revealed inoculation messages to be superior to both supportive messages and no-treatment controls at conferring resistance. Additionally, the results revealed refutational same and refutational different preemptions to be equally effective at reducing attitude change. However, the data were not consistent with some predictions made in narrative reviews of inoculation. No significant increase in resistance as a function of threat or involvement was found. Further, instead of a curvilinear effect for delay on resistance, the point estimates from our meta-analysis revealed equivalent resistance between immediate and moderate delays between inoculation and attack, with a decay in resistance after two weeks.

Examining the Scope of Channel Expansion A Test of Channel Expansion Theory With New and Traditional Communication Media

This article draws on channel expansion theory to explore the selection and use of communication media by organizational members. Channel expansion theory scholars posit that media richness perceptions are dependent on experiences with communication partners, the message topic, and the communication media utilized. This study tests channel expansion theory in the context of new and traditional communication media. Respondents (N = 269) completed questionnaires regarding their use and perceptions of face-to-face, telephone, e-mail, or instant-messaging interactions. Results indicate that experience with channel, topic, partner, and social influence are all significant predictors of richness perceptions, when controlling for age and media characteristics. Findings also suggest that the richness of a medium is not fixed and may be shaped by interpersonal factors, including ones relevant experiences.

Health at High Speed: Broadband Internet Access, Health Communication, and the Digital Divide

The study reported here explored the broadband digital divide in the context of Internet-based health communication. Inequities in the adoption of broadband technology were examined and the comprehensive model of health information seeking (CMIS) was used to make predictions about the implications of broadband Internet for personal health. Data from a population-based survey conducted by the National Cancer Institute in 2005 (N = 5,586) were analyzed. Results showed that those who were younger, more educated, and lived in an urban area were more likely to have a broadband Internet connection in their home. Furthermore, consistent with the CMIS, those with a broadband connection were more likely to use the Internet for health-related information seeking and communication than those with a dial-up connection.

Leveling the Organizational Playing Field—Virtually A Meta-Analysis of Experimental Research Assessing the Impact of Group Support System Use on Member Influence Behaviors

One of the most heralded features of group support systems (GSSs) is their ability to democratize group processes. Through minimizing barriers to communication, GSSs are proposed to create greater opportunities for member influence than those created in groups meeting face-to-face. To test this notion, a meta-analysis was conducted examining the aggregate impact of GSS use on six influence variables across 48 experiments. Results indicate that groups using a GSS experience greater participation and influence equality, generate a larger amount of unique ideas, and experience less member dominance than do groups meeting face-to-face. The impact of GSS use on decision shifts is moderated by the national culture of participants. The implications of these findings for research on GSS use are examined, and directions for future research are offered.

Communicating Social Support in Computer-mediated Contexts: A Meta-analytic Review of Content Analyses Examining Support Messages Shared Online among Individuals Coping with Illness

Research on social support during the past two decades has been marked by a growth in scholarship examining supportive communication in computer-mediated contexts among individuals coping with illness. In an effort to summarize and advance this body of research, a meta-analytic review of content analyses was conducted. Across the 41 content analyses examining social support messages shared in health-related contexts online, informational and emotional support messages were most prevalent. Additionally, the prevalence of particular types of support messages varied based on several stressor dimensions relevant to illness. Nurturant forms of support were more common among content analyses examining health conditions likely to threaten personal relationships as well as among content analyses focusing on health conditions with a greater potential for loss in the form of death. Action-facilitating types of support were more common among content analyses examining more chronic conditions. The findings from this project offer insights about the nuanced ways in which computer-mediated communication is used as a resource for coping with illness.

What can we learn about social network sites by studying Facebook? A call and recommendations for research on social network sites

The substantial growth in research examining social network sites (SNSs) during recent years makes this an opportune time to reflect on the state of SNS scholarship. In this review, we consider what—in the form of specific brands—has been studied. A content-analysis of SNS research published in six interdisciplinary journals between 1997 and 2013 is first reported to better understand the degree to which studies published in these journals have examined various SNS brands (e.g. Facebook, MySpace, Cyworld, Hyves). The results show that more than two-thirds of SNS studies were explicitly limited to a single brand and that Facebook was the brand examined in approximately 80% of these studies. Five implications of this trend are then discussed as potentially limiting what can be learned in aggregate from such a body of SNS scholarship. The review concludes with recommendations for future research on SNSs.

Information Sources and the Health Information-Seeking Process: An Application and Extension of Channel Complementarity Theory

Contemporary information seekers can acquire health information from an unprecedented variety of sources. The reported study applied and extended channel complementarity theory to explain the use of multiple information sources in the health-information-seeking process. Channel complementarity was extended to consider four characteristics (i.e., access to medical expertise, tailorability, anonymity, and convenience) of health-information sources. The information-seeking behavior of 3,392 respondents from the 2007–2008 Health Information National Trends Survey was analyzed to test study hypotheses. Results indicate that, sources were used complementarily based on tailorability and anonymity during health-information sources. Additionally, the likelihood of using complementary sources based on all four characteristics changed during the search process.
