The study reported here examined the influence of anonymous sources on health websites on the perceptions and attitudes of information seekers. It was hypothesized that, despite the warnings and guidelines established by health organizations, anonymous sources would be perceived to be as credible and influential as sources that were identified. The anonymity effect, drawn from the similarity principle in attribution theory, was forwarded as a theoretical mechanism to explain responses to anonymous sources. The results indicated that anonymous sources were generally perceived by participants to be as credible and influential as identified sources, although the anonymity effect explanation was not supported. The implications of these findings for information seekers and health practitioners are considered. 相似文献

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. 相似文献

This essay examines the rather complex role of anonymity in communication research as revealed in the narratives submitted to this special issue. First, narratives were examined quantitatively to assess the prevalence of issues related to anonymity, with terms such as “anonymous” and “confidential” emerging most often. Next, a thematic analysis of the narratives suggests five tensions discussed in some detail: anonymity or (not and) confidentiality, over-promising and under-delivering anonymity, to sign and record … or not, named vs. anonymous vs. pseudonymous, and whether institutional review boards (IRBs) should be anonymous. The essay concludes with several applied recommendations for IRBs, researchers, and participants as they confront these tensions linked to the role of anonymity in human subjects research. 相似文献

Despite the benefits of using online social support groups, prior research does not provide a solid understanding of the online factors related to an individual’s supportive interaction. Accordingly, this study aims to explore how various aspects of anonymity predict different levels of social support engagement. The current study uncovers that visually identifiable group members are more likely to get supportive responses than are visually anonymous members. Also, when support group members are visually and discursively identifiable, they are more likely to get supportive messages than those who are visually and discursively anonymous. Additionally, the more identifiable support group members are, the more they receive positive messages. Practical implications for the role of social support group members’ anonymity/identifiability on the overall social support process are presented. 相似文献

An experiment was conducted (N = 170) to determine the role of civility and anonymity in online comments received for a news story. Dependent variables were (a) interest in the discussion, (b) favorability toward the comments, (c) favorability toward the commenter, and (d) trust in the information. Participants exposed to uncivil comments viewed the commenter less favorably and reported less trust in the information in the comment. Anonymity had no effect on the dependent variables, in contrast to expectations derived from social presence theory. Findings revealed that politeness of comments affected participants’ overall perceptions of the content of the online discussion. 相似文献

Seeking health-related information on behalf of or because of others is a common activity in everyday life and a topic of constant interest across multiple disciplines. The research aims to characterize recent research progress and provide a comprehensive framework of proxy health information-seeking behavior (PHISB). A total of 47 studies published after 2003 were selected, followed by structural encoding. The main contributions include 1) a summary of the key characteristics of individuals who often access health information through proxy seekers; 2) types of health information surrogates sought and sources employed; 3) a classification scheme of factors influencing PHISB; 4) a synthesis of how health information used and its subsequent outcomes; 5) a theoretical framework for proxy health information-seeking. Results point to an intellectual benchmark for future exploring related issues. The findings can shed light on public health intervention and management, especially through guiding search strategies to help people obtain relevant, helpful, and credible health information. 相似文献

Background: While the Internet is a popular source of health information, health seekers’ inadequate skills to locate and discern quality information pose a potential threat to their healthcare decision‐making. Objectives: We aimed to examine health information search and appraisal behaviours among young, heavy users of the Internet. Methods: In study 1, we observed and interviewed 11 college students about their search strategies and evaluation of websites. In study 2, three health experts evaluated two websites selected as the best information sources in study 1. Results: Familiarity with health websites and confidence in search strategies were major factors affecting search and evaluation behaviours. Website quality was mostly judged by aesthetics and peripheral cues of source credibility and message credibility. In contrast to users’ favourable website evaluation, the experts judged the websites to be inappropriate and untrustworthy. Conclusion: Our results highlight a critical need to provide young health seekers with resources and training that are specifically geared toward health information search and appraisal. The role of health seekers’ knowledge and involvement with the health issue in search effort and success warrants future research. 相似文献

Cognitive authorities in health education classrooms: A nexus analysis on group-based learning tasks
Socio-technical changes have transformed information practices and challenged conceptions of cognitive authorities, referring to information sources that are deemed credible and legitimate and influence people's thinking. Cognitive authorities in group-based knowledge-construction projects in health education lessons were explored in this study. Nexus analysis was used to analyze participant interviews and video-observed social actions in three secondary school health-education classrooms (Grades 8–9) in Finland. The findings show how group-based projects employing multiple information sources offer opportunities for the distribution and co-construction of cognitive authorities. However, explicit negotiations on the authority of sources were rare. Cognitive authorities appeared as contextual and situational but also guided by broader discourses circulating in the scene of action. By embedding information literacy instruction throughout the curriculum, information professionals and teachers can support young learners to recognize relevant authorities in different spheres of knowledge and to become competent users of health information. 相似文献

Health information seeking is an important part of older adults' everyday lives as they cope with their health conditions. Semi-structured interviews conducted with 21 older adults in the United States were analyzed using Savolainen's everyday life information seeking (ELIS) model, especially its key concepts such as way of life and mastery of life. The interview data revealed that except for health care providers, a spouse or partner was mentioned as a credible interpersonal source of health information among older adults in a marital or romantic relationship. Characteristics of older adults' health information behavior in the ELIS context were identified based on types of way of life and mastery of life. For example, those who had more varied types of hobbies, including cognitive, affective, and social hobbies, were exposed to diverse people as they performed their daily routine, potentially resulting in different sources of useful health information. In couple relationships, those with an optimistic as opposed to pessimistic attitude toward a problem-solving situation played the information provider role rather than information receiver role. 相似文献

This study investigated the effect of perceived teacher burnout on perceived teacher credibility. One hundred eighty-two college students were randomly exposed to a written scenario manipulating the level of perceived teacher burnout (high or low) and responded to a scale measuring perceived teacher credibility in reference to the scenario. Results of one-way multivariate analyses of variance indicated that perceived teacher burnout has a negative impact on perceived teacher competence, caring, and trustworthiness. Low-burnout teachers are perceived as more credible than high-burnout teachers. 相似文献

The extent to which information sources, that stand behind virtually all the news, are perceived by journalists as credible is a key determinant of the likelihood of their obtaining news access and public voice. The nature of source credibility judgment in journalism, however, is disputed between two major schools: while the “visceral” camp contends that it is highly subjective, intuitive and biased, the “discretional” camp perceives it as a far more reasonable and legitimate journalistic tool. The present study attempts to uncover evidence of both “visceral” and “discretional” judgment by studying the conceptual credibility (trustworthiness ratings) and practical credibility (practices indicating trust or skepticism, such as cross-checking and attribution) and the congruence between the two in a sample of 840 news items based on 1870 news sources. Findings were gleaned in face-to-face reconstruction interviews with reporters from nine leading Israeli news organizations, who reconstructed, source by source, the processes behind their items, shortly after their publication. Pro-discretional evidence shows that while journalists perceive their own experience as more credible than that of any other human agent, they do tend to stick with sources they perceive as more credible, the majority of which were relied on in the past, granting them more ready acceptance. Pro-visceral evidence, in turn, demonstrates that even the least credible sources receive substantial news space, some without any cross-checking. Furthermore, reporters ranked their sources' credibility even when they had no former record of trustworthiness. The paper suggests interpreting the composite of these findings as discretional logic with islands of visceral judgment. 相似文献

Immigrants encounter cultural adaptation challenges impacting their health behaviors and outcomes, with health information and cultural factors influencing their actions. A survey of 340 participants from Finland, Norway, and Sweden was conducted, and the data were analyzed using structural equation modelling. Results show that health beliefs and access to health information, mainly via the Internet, significantly predict immigrants' intentions to engage in health-related actions, while perceived barriers negatively affect their adoption of healthy behavior. The findings underscore the importance of information professionals in providing culturally relevant health information and resources to immigrants and emphasize the need for policymakers to consider cultural factors and information sources in health promotion efforts targeting immigrant populations. This study adds value to the information science literature by highlighting the role of information access and cultural context in shaping health-related actions among immigrants in Nordic countries. 相似文献

The purpose of this study is to provide a comprehensive investigation on perceived media credibility in China. In order to assess people's attitudes toward six media formats (television [TV], newspapers, radio, magazines, websites, and mobile devices), a series of surveys were conducted with a random sample of 5807 residents in 10 cities in China. Findings indicated that Chinese respondents perceived TV to be the most credible among all media and that TV was rated as more credible than newspapers. In addition, two official mouthpieces, China Central Television and the People's Daily, were both perceived to be highly credible. But readership in general was a nonfactor in terms of credibility. These findings challenged conventional thinking on media credibility. Implications and directions for future research are discussed. 相似文献
