跨源健康信息搜寻的动机、信息源选择及行为路径

本研究旨在探究用户面临多种健康信息源时的跨源健康信息搜寻行为,揭示这类信息搜寻行为的动机、信息源选择和行为路径。结合日记法和半结构化深度访谈法,收集并分析了26名参加者的健康信息搜寻日记及跟踪访谈数据,使用NVivo11分析数据。研究发现医生-用户交流障碍、信任缺失、用户自我调节和用户安全心理的需要是促使跨源健康信息搜寻行为产生的动机。相似病症用户的自我陈述、用户的路径依赖(习惯)、从众心理、信息源的权威性及可信度是影响用户跨源过程中信息源选择的主要因素。此外,用户跨源搜寻健康信息的过程中,其心理需求大于实际需求、凭“感觉”感知网络健康信息质量等特征较明显。本研究构建了跨源健康信息搜寻行为路径模型,研究的结果有助于提升用户健康信息搜寻行为认知,改善其跨源健康信息获取能力,提升其健康信息素养;同时,也为相关部门制定提升公民健康信息素养策略及支持跨源健康信息搜寻行为的信息系统的开发和设计提供了借鉴。     

Improving the Effectiveness of Fundraising Messages: The Impact of Charity Goal Attainment,Message Framing,and Evidence on Persuasion

This experimental study assessed the effectiveness of fundraising messages. Based on recent findings regarding the effects of message framing and evidence, effective fundraising messages should combine abstract, statistical information with a negative message frame and anecdotal evidence with a positive message frame. In addition, building on research into social dilemmas, it was hypothesized that information about charity goal attainment (e.g., the contributions of others) should increase donation intentions. The hypotheses were tested in a 2 (goal attainment: yes/no)×2 (framing: positive/negative)×2 (evidence: statistical/anecdotal) factorial design. Abstract information was more effective when combined with a negatively framed message, whereas anecdotal information was more effective when combined with a positive frame. In addition, donation intentions were higher for messages that addressed charity goal attainment issues.

Health information seeking behaviour: the librarian's role in supporting digital and health literacy

This paper is based on Rachel Butler's dissertation carried out at the University of Sheffield as part of the MA Library and Information Services Management. The study examines people's online health information seeking skills, with the specific aim to identify how libraries and health services can work together in supporting digital and health literacy. A survey approach is used to explore online searching habits as well as librarian and health professionals’ views on health literacy. The key findings indicate that whilst the majority of respondents consider themselves to be health literate, there was an overall agreement that effective education and support could be achieved through the collaboration between libraries and health services, and specifically to signpost information and to provide targeted education. The limitations of the research for dissertation are recognised leading to recommendations that further study focuses on the impact of signposting and education on health literacy.F.J.     

Assessing internet access and use in a medically underserved population: implications for providing enhanced health information services

Background: The relationship between health information seeking, patient engagement and health literacy is not well understood. This is especially true in medically underserved populations, which are often viewed as having limited access to health information. Objective: To improve communication between an urban health centre and the community it serves, a team of library and information science researchers undertook an assessment of patients’ level and methods of access to and use of the Internet. Methods: Data were collected in 53 face‐to‐face anonymous interviews with patients at the centre. Interviews were tape‐recorded for referential accuracy, and data were analysed to identify patterns of access and use. Results: Seventy‐two percentage of study participants reported having access to the Internet through either computers or cell phones. Barriers to Internet access were predominantly lack of equipment or training rather than lack of interest. Only 21% of those with Internet access reported using the Internet to look for health information. Conclusion: The findings suggest that lack of access to the Internet in itself is not the primary barrier to seeking health information in this population and that the digital divide exists not at the level of information access but rather at the level of information use.     

Online health information search and evaluation: observations and semi-structured interviews with college students and maternal health experts

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.

Strategic topic avoidance: an investigation of topic avoidance frequency,strategies used,and relational correlates

This research stresses the need to examine the relationship between topic avoidance and relational correlates (e.g., satisfaction and emotional closeness) from a message production theoretical perspective. Our approach—strategic topic avoidance—offers additional explanatory capabilities as the strategies with which interactants in close relationships avoid topics may be associated with perceptions of the relationship (after accounting for topic avoidance frequency). Moreover, relational correlates may also vary by the combination of overall topic avoidance frequency and certain topic avoidance strategies. The current research, therefore, assessed individuals' topic avoidance frequency levels and the frequency of using topic avoidance strategies in relation to satisfaction and closeness across three different relational types (i.e., significant others, mother–young‐adult, and father–young‐adult relationships). Results suggested that avoiding certain topics, such as current relational concerns, predicted levels of satisfaction and closeness across relationship types; however, cross‐relational differences also emerged. Strategies employed to avoid topics accounted for additional variance in satisfaction and closeness for relationships with significant others and mothers but not fathers. Analyses also demonstrated that overall topic avoidance frequency interacted with topic avoidance strategy use.     

Health Information and Health Literacy: Public Library Practices,Challenges, and Opportunities

This study investigated 18 libraries in two public library systems in Oklahoma to find out how they are addressing health literacy and facilitating access to consumer health information; how library staff members view their roles and responsibilities relative to health information and health literacy; what challenges libraries face; and what strategies are being used. Staff members recognized several challenges to providing health information and to developing programs, including staff and patron difficulties with reference interviews, and patron lack of awareness of library resources. Staff members often had only a partial understanding of health literacy, and were unaware of system strategies to address health literacy or provision of health information.     

Spokespersons and Message Control: How the CDC Lost Credibility during the Anthrax Crisis This paper was presented to the Red River Communication Conference April 22, 2004.

This study evaluates the role of spokespersons and message control in complex organizations facing ambiguous crises. Specifically, the Centers for Disease Control and Prevention's (CDC) response to the anthrax crisis in 2001 is offered as a case study. A textual analysis of CDC telebriefings and corresponding print media coverage of the anthrax crisis reveals the use of multiple spokespersons and poor message control resulted in a seemingly fragmented CDC message and apparent loss of CDC credibility. The study concludes that limiting the number of spokespersons and appropriate use of strategic ambiguity may afford organizations an opportunity to make sense of the situation, avoid confusing and contradictory messages and protect organizational credibility. Recommendations include (1) limiting the number of spokespersons, which allows for greater message control while reducing contradictory and inconsistent messages, (2) maintaining an organizational willingness to revise publicly stated positions as more accurate information becomes available, and (3) actively using strategic ambiguity as a mechanism to protect organizational credibility.
