Electronic vs. traditional textbook use: dental students' perceptions and study habits.

This descriptive study assessed dental students' attitudes about computer use as it relates to study habits and use of e-textbook technology. Academic deans and student leaders at all accredited dental education programs in the United States, Puerto Rico, and Canada were asked to forward an e-mail to students explaining the purpose of the study and asking them to participate. The e-mail included an embedded URL link to the survey. A total of 703 complete responses from twenty-four dental schools were received and used in the final analysis. Because the number of students contacted could not be determined, the overall response rate cannot be calculated. Over 65 percent of the respondents reported spending >11 hours per week studying although over 75 percent said they spent little time studying from their textbooks. Over 55 percent were from schools that use e-textbooks exclusively, with 25 percent from schools that exclusively use print textbooks. One-fourth indicated they purchased a traditional printed textbook even when an e-textbook was provided; more than one-third printed information from the e-textbooks rather than reading on the computer. A majority (59 percent) preferred traditional textbook resources over e-textbooks, with over 50 percent reporting not using the required e-textbooks at all. E-textbooks were used by students in this study less frequently than materials/notes provided by dental school faculty. The majority preferred to use traditional resources as references and for augmenting lecture material.

Demand for and availability of online support to stop smoking.

OBJECTIVES: Estimate the frequency of online searches on the topic of smoking and analyze the quality of online resources available to smokers interested in giving up smoking. METHODS: Search engines were used to revise searches and online resources related to stopping smoking in Brazil in 2010. The number of searches was determined using analytical tools available on Google Ads; the number and type of sites were determined by replicating the search patterns of internet users. The sites were classified according to content (advertising, library of articles and other). The quality of the sites was analyzed using the Smoking Treatment Scale- Content (STS-C) and the Smoking Treatment Scale - Rating (STS-R). RESULTS: A total of 642,446 searches was carried out. Around a third of the 113 sites encountered were of the 'library' type, i.e. they only contained articles, followed by sites containing clinical advertising (18.6) and professional education (10.6). Thirteen of the sites offered advice on quitting directed at smokers. The majority of the sites did not contain evidence-based information, were not interactive and did not have the possibility of communicating with users after the first contact. Other limitations we came across were a lack of financial disclosure as well as no guarantee of privacy concerning information obtained and no distinction made between editorial content and advertisements. CONCLUSIONS: There is a disparity between the high demand for online support in giving up smoking and the scarcity of quality online resources for smokers. It is necessary to develop interactive, customized online resources based on evidence and random clinical testing in order to improve the support available to Brazilian smokers.
