Comparison of Quality of Internet Pages on Human Papillomavirus Immunization in Italian and in English

Purpose: Information available on the Internet about immunizations may influence parents' perception about human papillomavirus (HPV) immunization and their attitude toward vaccinating their daughters. We hypothesized that the quality of information on HPV available on the Internet may vary with language and with the level of knowledge of parents. To this end we compared the quality of a sample of Web pages in Italian with a sample of Web pages in English. Methods: Five reviewers assessed the quality of Web pages retrieved with popular search engines using criteria adapted from the Good Information Practice Essential Criteria for Vaccine Safety Web Sites recommended by the World Health Organization. Quality of Web pages was assessed in the domains of accessibility, credibility, content, and design. Scores in these domains were compared through nonparametric statistical tests. Results: We retrieved and reviewed 74 Web sites in Italian and 117 in English. Most retrieved Web pages (33.5%) were from private agencies. Median scores were higher in Web pages in English compared with those in Italian in the domain of accessibility (p < .01), credibility (p < .01), and content (p < .01). The highest credibility and content scores were those of Web pages from governmental agencies or universities. Accessibility scores were positively associated with content scores (p < .01) and with credibility scores (p < .01). A total of 16.2% of Web pages in Italian opposed HPV immunization compared with 6.0% of those in English (p < .05). Conclusions: Quality of information and number of Web pages opposing HPV immunization may vary with the Web site language. High-quality Web pages on HPV, especially from public health agencies and universities, should be easily accessible and retrievable with common Web search engines.

How content contributors assess and establish credibility on the web

The proliferation of user‐generated content (UGC) is one of the distinguishing characteristics of Web 2.0. Internet users contribute content online through platforms such as blogs, wikis, video sharing sites, and sites that allow user feedback. Yet little is known of the credibility practices of these content contributors. Through phone interviews conducted with 29 online content contributors, this study investigates how content contributors assess credibility when gathering information for their online content creation and mediation activities, as well as the strategies they use to establish the credibility of the content they create. These contributors reported that they engaged in content creation activities such as posting or commenting on blogs or online forums, rating or voting on online content, and uploading photos, music, or video. We found that credibility judgments made when gathering information for online content creation and mediation activities could be grouped into three levels: intuitive, heuristic, and strategy‐based. We identified three distinctive ways of establishing credibility that are applied during different phases of content contribution: ensuring credibility during the content creation phase; signaling credibility during the content presentation phase; and reinforcing credibility during the post‐production phase. We also discovered that content contributors tend to carry over the strategies they used for assessing credibility during information gathering to their strategies for establishing the credibility of their own content. Theoretical implications for credibility research and practical implications for developing information literacy programs are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90253/1/14504801163_ftp.pd

Developing a theoretical framework for web credibility assessment—A case of social Q&A sites: preliminary findings

As part of a larger study, this poster reports on preliminary findings of efforts to develop a theoretical framework for assessing the credibility of information on social question-and-answer (Q&A) sites. A literature analysis was conducted to identify relevant criteria for assessing web credibility on social Q&A sites, which were then mapped to an existing framework of web credibility assessment [1]. Specifically, 21 criteria identified by the literature analysis were categorized into one of six types of web credibility assessments—operator (author) trustworthiness, operator (author) expertise, con-tent trustworthiness, content expertise, design trustworthiness, and design expertise—to develop an information platform type-specific framework of in-formation credibility. Results show that existing criteria used in the literature have focused primarily on content-related attributes (e.g., evidence-based, structural completeness, and semantic clarity and comprehensive-ness), but less on operator (author)-related attributes (e.g., credentials) or de-sign features (e.g., interactive design, appropriateness of design, ease of use). Implications of the findings and future research directions are discussed

On the sustainability of web systems evolution

In the last twenty years, the evolution of web systems has been driven along three dimensions: the processes used to develop, evolve, maintain and re-engineer the systems themselves; the end products (the pages, content and links) of such processes; and finally the people dimension, with the extraordinary shift in how developers and users shape, interact and maintain the code and content that they put online. This paper reviews the questions that each of these dimensions has addressed in the past, and indicates which ones will need to be addressed in the future, in order for web system evolution to be sustainable. We show that the study on websites evolution has shifted from server- to client-side, focusing on better technologies and processes, and that the users becoming creators of content open several open questions, in particular the issue of credibility of the content created and the sustainability of such resources in the long term

The Impact of Visual Design on Web Persuasiveness

Many commentators of web persuasion have suggested that content is the key factor responsible for creating credible (and therefore persuasive) websites. Research in a variety of fields has been devoted to identifying accurate methods of determining a website\u27s trustworthiness in order to help organizations promote credibility and teach users to critically analyze it. By focusing on the credibility of content, however, researchers are promoting an unbalanced perspective of web persuasiveness that privileges textual content over visual design. This thesis hypothesizes that visual design significantly impacts web persuasiveness. First, exploration of current theories of web persuasiveness reveals the importance of persuasion in measuring a website\u27s success and the need to expand consideration of persuasive factors beyond the credibility of content. Next, Chapter 2 demonstrates the impact of visual design through explanation of the perceptual process and the theory of halo effect. Then, design principles from theorists such as Tufte, Kress and Van Leeuwen, Mullet and Sano, and Kostelnick and Roberts are suggested as a means for determining whether or not a visual design is \u27attractive.\u27 To study the effects of these design principles (or their absence) on web persuasiveness, I conducted a pilot study where one group of participants used an \u27attractive\u27 website while another group used an \u27unattractive\u27 version of the same website. Results from this study suggest that visual design does have a positive impact on web persuasion

How online search behavior is influenced by user-generated content on review websites and hotel interactive websites

ABSTRACT: Purpose – The purpose of this paper is to advance in research on consumer Psychology of hospitality, since it investigates how online search behavior of users (particularly, information search and choice) is influenced by the opinions of other people in a new context characterized by the generalized use of Web 2.0 applications. Design/methodology/approach – Empirical research was carried out in the hotel sector in Iberian Peninsula, where two Web 2.0 applications are especially relevant for users: the review Web sites and the hotel interactive Web sites. A qualitative method (in-depth interviews with hotel managers) and a quantitative technique (personal surveys to a sample of 830 users) were used to conduct this research. Findings – The results indicates that the perceived influence on behavior of the user-generated content on these Web 2.0 applications is determined, in both cases, by the value of the information, the credibility of the sources and the degree of similarity between the user and the creators of content. Practical implications – Firms should have an active presence in the review Web sites and the hotel interactive Web sites, and use these platforms for market research and communication. Firms should engage users to post content, support their credibility and facilitate the evaluation of the content generators’ similarity. Originality/value – This paper is the first study in the hospitality literature that develops and empirically tests an integrative model explaining the perceived influence on behavior of user-generated content on Web 2.0 applications

Online Information on Dysmenorrhea: An Evaluation of Readability, Credibility, Quality, and Usability

Aims and objectives To evaluate online information on dysmenorrhoea, including readability, credibility, quality and usability. Background Menstrual pain impacts 45%–95% of women of reproductive age globally and is the leading cause of school and work absences among women. Women often seek online information on dysmenorrhoea; however, little is known about the information quality. Design This was a descriptive study to evaluate online information on dysmenorrhoea. Methods We imitated search strategies of the general public. Specifically, we employed the three most popular search engines worldwide—Google, Yahoo and Bing—and used lay search terms, “period pain” and “menstrual cramps.” We screened 60 web pages. Following removal of duplicates and irrelevant web pages, 25 met the eligibility criteria. Two team members independently evaluated the included web pages using standardised tools. Readability was evaluated with the Flesch–Kincaid Reading Ease and Flesch–Kincaid Grade formulas; credibility, quality and usability were evaluated with established tools. We followed the STROBE checklist for reporting this study. Results For readability, the mean Flesch–Kincaid level was 10th grade. For credibility, 8% of web pages referenced scientific literature and 28% stated the author's name and qualifications. For quality, no web page employed user‐driven content production; 8% of web pages referenced evidence‐based guidelines, 32% of web pages had accurate content, and 4% of web pages recommended shared decision‐making. Most web pages were interactive and included nontextual information. Some nontextual information was inaccurate. Conclusion Online information on dysmenorrhoea has generally low readability, mixed credibility and variable quality. Relevance to clinical practice Strategies to improve health information on dysmenorrhoea include avoiding complex terms, incorporating visual aids, presenting evidence‐based information and developing a decision aid to support shared decision‐making. Healthcare providers should be aware of the problematic health information that individuals are exposed to and provide education about how to navigate online health information

MEDQUAL: Improving Medical Web Search over Time with Dynamic Credibility Heuristics

Performing a search on the World Wide Web (WWW) and traversing the resulting links is an adventure in which one encounters both credible and incredible web pages. Search engines, such as Google, rely on macroscopic Web topology patterns and even highly ranked 'authoritative' web sites may be a mixture of informed and uninformed opinions. Without credibility heuristics to guide the user in a maze of facts, assertions, and inferences, the Web remains an ineffective knowledge delivery platform. This report presents the design and implementation of a modular extension to the popular Google search engine, MEDQUAL, which provisions both URL and content-based heuristic credibility rules to reorder raw Google rankings in the medical domain. MEDQUAL, a software system written in Java, starts with a bootstrap configuration file which loads in basic heuristics in XML format. It then provides a subscription mechanism so users can join birds of feather specialty groups, for example Pediatrics, in order to load specialized heuristics as well. The platform features a coordination mechanism whereby information seekers can effectively become secondary authors, contributing by consensus vote additional credibility heuristics. MEDQUAL uses standard XML namespace conventions to divide opinion groups so that competing groups can be supported simultaneously. The net effect is a merger of basic and supplied heuristics so that the system continues to adapt and improve itself over time to changing web content, changing opinions, and new opinion groups. The key goal of leveraging the intelligence of a large-scale and diffuse WWW user community is met and we conclude by discussing our plans to develop MEDQUAL further and evaluate it
