青少年能够在互联网上获取健康信息，部分是因为他们有能力搜索和找到与健康有关的问题的答案。青少年可能有独特的健康和计算机知识需求。虽然许多调查、访谈和焦点小组已经被用来了解青少年在网上寻找健康信息的信息寻求和信息检索行为，但我们无法找到在这种情况下对青少年个体进行的观察。本研究旨在了解青少年如何使用互联网搜索健康信息，以及这可能对获取健康信息产生什么影响。从密歇根州东南部的1所初中和2所高中选取12名学生（12-17岁）作为方便样本，向他们提供6个与健康相关的问题，并要求他们使用互联网寻找答案。研究人员使用捕捉屏幕图像和同步录音的软件记录了68个特定的搜索。后来对录音进行了审查，并对具体的搜索技术和策略进行了编码。对口头交流也进行了定性评价。在观察到的68次搜索中，47次（69%）成功，因为青少年找到了健康问题的正确和有用的答案。学生尝试访问的大多数网站是直接从搜索引擎结果（77%）或搜索引擎推荐链接（10%）中检索到的；只有一小部分是直接访问（5%）或从其他网站链接（7%）。大多数（83%）来自搜索引擎结果的链接来自前9个结果。拼写错误（132个搜索词中的30个）、网站内访问的页面数量（范围从1-15个）和整体搜索策略（例如，使用搜索引擎还是直接访问网站）都是成功的重要决定因素。定性分析显示，参与者使用试错法来制定搜索字符串，随机而不是系统地扫描页面，并且在搜索健康信息时不考虑内容的来源。这项研究为当前青少年的搜索模式提供了一个有用的快照。研究结果对构建青少年搜索行为的真实模拟、改善与青少年相关的健康信息网站的分布和有用性、提高教育者对学生可能遇到的具体陷阱的认识具有重要意义。
Adolescents' access to health information on the Internet is partly a function of their ability to search for and find answers to their health-related questions. Adolescents may have unique health and computer literacy needs. Although many surveys, interviews, and focus groups have been utilized to understand the information-seeking and information-retrieval behavior of adolescents looking for health information online, we were unable to locate observations of individual adolescents that have been conducted in this context. This study was designed to understand how adolescents search for health information using the Internet and what implications this may have on access to health information. A convenience sample of 12 students (age 12-17 years) from 1 middle school and 2 high schools in southeast Michigan were provided with 6 health-related questions and asked to look for answers using the Internet. Researchers recorded 68 specific searches using software that captured screen images as well as synchronized audio recordings. Recordings were reviewed later and specific search techniques and strategies were coded. A qualitative review of the verbal communication was also performed. Out of 68 observed searches, 47 (69%) were successful in that the adolescent found a correct and useful answer to the health question. The majority of sites that students attempted to access were retrieved directly from search engine results (77%) or a search engine's recommended links (10%); only a small percentage were directly accessed (5%) or linked from another site (7%). The majority (83%) of followed links from search engine results came from the first 9 results. Incorrect spelling (30 of 132 search terms), number of pages visited within a site (ranging from 1-15), and overall search strategy (eg, using a search engine versus directly accessing a site), were each important determinants of success. Qualitative analysis revealed that participants used a trial-and-error approach to formulate search strings, scanned pages randomly instead of systematically, and did not consider the source of the content when searching for health information. This study provides a useful snapshot of current adolescent searching patterns. The results have implications for constructing realistic simulations of adolescent search behavior, improving distribution and usefulness of Web sites with health information relevant to adolescents, and enhancing educators' knowledge of what specific pitfalls students are likely to encounter.
