ABSTRACTYoung adults struggle to achieve sexual health. Student health centers (SHCs) are uniquely positioned to provide young adults with credible and complete sexual health information. Using the comprehensive model of information seeking for theoretical guidance, we conducted a content analysis to examine the credibility and completeness of sexual health information available to young adults through SHC websites at 400 randomly selected U.S. colleges/universities. Unfortunately, most SHC websites do not provide complete sexual health information, which may decrease the credibility of SHCs as a source of sexual health information for young adults. Topics related to sexual health predominantly focused on prevention and risk topics (i.e. sexually transmitted diseases, contraception, and pregnancy). We offer practical suggestions for SHC webpages to align their sexual health information content with the American College Health Association standards of practice and point to a scholarly focus on content characteristics and information availability to complement information seeking studies. 相似文献

跨源健康信息搜寻的动机、信息源选择及行为路径 总被引：1，自引：0，他引：1
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。 相似文献

Public librarians in South Korea assist users in obtaining information on a variety of topics. However, health-related information and services have a lower profile than other services due to a perceived lack of librarian expertise in searching and evaluating health resources. Although public library users are actively seeking health information, it has become critical for both public librarians and users to develop skills for using and evaluating Internet health resources. Therefore, this study was conducted to identify a set of useful criteria to evaluate online health web sites for both librarians and library users. From a comprehensive literature review, 33 criteria related to health website evaluation were identified. Using this set of criteria, South Korean public librarians and users were asked to rate the importance of each criterion in surveys. A strong consensus was found between the two groups. The top 10 most highly rated criteria from both groups were identified and compared. The results led to the development of an initial set of 12 evaluation criteria for health websites. It is expected that the final set of criteria will be used by public librarians to recommend the best health websites to their users. Although the study was conducted in South Korean public libraries, the findings are applicable in providing evaluation services of health websites to libraries worldwide. 相似文献

The Internet provides an easy and accessible way to deliver medical information about the management of various diseases, both to practitioners and to their patients. As there is no control over who posts information on the Web, there is a risk that the interests of the web producer may bias the quality of information. The quality of medical information on the management of chronic obstructive pulmonary disease (COPD) on the Internet was evaluated, comparing non-commercial and commercial websites. An internet search was conducted to locate relevant websites using a metasearch engine. The quality of websites was scored on a scale of 0-10, based on three items about the credibility of the site and seven items about the accuracy of the information provided by the site. Quality differences between commercial and non-commercial websites were explored. The search revealed 23 relevant websites (12 noncommercial and 11 commercial). The overall quality of non-commercial websites was better than that of commercial websites (median score 7 vs. 4, P = 0.01). Compared to commercial sites, non-commercial websites more often provided information about cessation of smoking (100% vs. 64%, P = 0.03), preventative influenza vaccinations (42% vs. 9%, P = 0.07) and use of long-term oxygen therapy (92% vs. 45%, P = 0.02). Among websites providing information on COPD, commercial sites were much more likely to be of poorer quality compared to sites of non-commercial organizations. In particular, commercial sites do not provide information about simple preventative treatments. There is a need to be vigilant about the quality of health information about COPD on the Internet. 相似文献

Objectives: To develop a patient information leaflet (PIL) to help local patients meet their drug information needs using the Internet, and to perform a preliminary evaluation of this tool. Methods: Development—a cross‐sectional survey of the drug information needs of local patients using a semi‐structured questionnaire; assessment of websites offering free, consumer‐orientated medicines information using set criteria; identification of consensus criteria to evaluate the quality of health‐related on‐line information; evaluation—views on a draft patient information leaflet from a focus group. Results: Those surveyed felt that being directed to high‐quality websites and being provided with assessment criteria for on‐line information would be useful. The three websites fulfilling most of the set quality criteria were Surgery Door ( www.surgerydoor.co.uk ), InteliHealth ( www.intelihealth.com ) and medline plus ( www.nlm.nih.gov/medlineplus ). The six most frequently cited assessment criteria were currency, authorship, commerciality, relevance, links and attribution. A draft leaflet was constructed listing the above three websites and six criteria along with tips on how to search the Internet effectively. A focus group reacted favourably. Conclusion: The Internet is a source of drug information—an information leaflet may help to guide local patients through its variable information quality. 相似文献

Google is the search engine of choice for most Internet users. For a variety of reasons, librarians and other expert searchers do not always use Google to its full potential, even though it provides capabilities not possible in traditional bibliographic databases and other search engines. Applying expert searching principles and practices, such as the use of advanced search operators, information retrieval strategies, and search hedges to Google will allow health sciences librarians to find quality information on the Internet more efficiently and effectively. 相似文献

信息源对数字原住民健康信息可信度判断的启发式实验研究 总被引：2，自引：0，他引：2
互联网已成为消费者健康信息搜寻的重要渠道。Web 2.0环境下互联网信息传播的路径和形态嬗变使在线健康信息环境日趋多样与复杂,用户在异质信息源中选择恰当健康信息的难度显著提升。本文基于启发式信息处理视角,从理论层面梳理启发式与健康信息可信度判断之间的内在关联并构建概念模型。在此基础上,采用实验研究法,以受控健康信息文本与启发式信息线索网页框架构建实验材料,并招募高中生群体这一典型的数字原住民作为被试开展实验研究。实验结果表明,各类健康信息来源中的启发式信息线索对数字原住民的可信度判断具有显著影响,特别是机构信息源线索的出现会显著提高数字原住民的可信度评价。数字原住民对机构信息源的可信度评价显著高于商业信息源与社会化媒体信息源,而商业信息源与社会化媒体信息源之间没有显著差别。研究结论有助于进一步理解数字原住民的健康信息行为模式,并为政府部门和公共卫生机构更好地构建健康信息平台提供参考依据。 相似文献

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. 相似文献

The Government in Britain is set on using the Internet to expand the provision of health information to the general public. Concerns over the quality of the health information have preoccupied commentators and organizations rather than the way users interact with health information systems. This report examines the issues surrounding the provision of electronic health information, and describes an evaluation undertaken of a commercial health website-that of Surgerydoor (http://www.surgerydoor.co.uk/), and comprises two parts. Part one outlines the literature on electronic health information evaluation. It discusses quality issues, but also redresses the imbalance by exploring other evaluative perspectives. Part two describes an evaluation of a health information Internet site in terms of its usability and appeal, undertaken as part of a Department of Health funded study on the impact of such systems. 相似文献

The current study investigates how social media affordances influence individuals’ source credibility perceptions in the presence of risk information, specifically examining how bandwagon heuristics interact with different identity heuristics at the individual level. The MAIN model and warranting theory serve as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. A posttest-only experiment with a self-report questionnaire was administered to participants. Results indicate that different online heuristic cues impact the judgments of competence, goodwill, and trustworthiness. Authority cues strongly influenced source credibility perceptions. A reverse-bandwagon effect was observed in influencing source credibility judgments. 相似文献
