Objective: With growing demand for health information and rapid development of information technology, health information websites are emerging as the most effective media to meet the public's needs for health information. This article is intended to offer a technical view on the design and operations of health information websites. Along this line, employed here is the Technology Acceptance Model (TAM), which has been widely used to predict user acceptance based on Perceived Ease-of-Use (PEOU) and Perceived Usefulness (PU). Methods: We extend the original TAM by including some exogenous variables since it is necessary to understand the role of the antecedents of acceptance constructs when designing an effective health information website for improving user satisfaction. This study focuses on identifying the core functional factors in designing and operating health information websites. Conducted are some multivariate statistical analyses based on data from an extensive survey. Results: The results from the structural equation analysis suggest that functional characteristics should be categorized into three groups: one affecting PU and PEOU, another affecting only PEOU, and the other having no direct effect on either PU or PEOU. In particular, 'usage support' and 'customization' are two key functional characteristics in the extended TAM framework for health information websites. Conclusion: Contrary to expectations, however, the direct effect of PEOU on usage support is hardly observed, which differentiates health information websites from other commercial websites like online shopping malls. As a result, understanding the antecedents of PU takes on more significance.
Understanding the Quality of Informational Health Websites: The Application of the Kano Model
2012
This study reports on an exploratory investigation of quality criteria classification of informational health websites using the Kano model. The results showed that quality features are of three types: (i) basic features which are the minimal requirements the consumers expect; (ii) performance features, which are the ones that maximize the consumers satisfaction with the health website; and (iii) the exciting features which are the delighters, the consumers do not consciously expect. The findings indicate that providing accessible website with high quality content that are friendly usable and trustworthy are basic quality features. On the other hand, features of visually appealing website, and human and/or automated feedback mechanisms are performance features that maximize the consumers satisfaction. Developing a health website that incorporates culturally-appropriate materials and employs interactive learning tools such as simulation or puzzles delights consumers and makes the website a leader in it space.
“Can I Trust You, Doc?”: User Perception Of Online Health Information
Klikdokter.com is one of websites that provides information service about health. Besides, it also provides live chat service i.e., question and answer about health which is directly claimed and answered by the specialist doctors. According to the survey conducted by IndoPacific Edelman and Research Unit and Community Service of Public Health Faculty of Indonesia University, the amount of 79% doctors believes in the most accurate health information source on the internet. Moreover, a study entitle Patients Use of the Internet for Medical Information shows that 53,5% out of 512 patients use internet as a media to find out information about health. The trust of doctors and internet users towards health information is indeed influenced by several factors. Therefore, the aim of this research is to analyze the factors that influence the trust of users towards the health information uploaded on klikdokter,com using ten construct variables. The data is collected from klikdokter.com users with 250 respondents. The data is analyzed using structural equation modeling analysis (SEM). The result shows that factors that influence Trust are perceived information quality, source expertise and argument quality.
The use of a methodology for the evaluation, comparison and quality improvement of Health Web Sites is justified by its widespread adoption and visibility to Internet users. Due to the sensitiveness of their content and impact on users, health related sites should be evaluated. This paper proposes three different dimensions for the development of quality evaluation methodologies of Health Web Sites: contents, services and technical. We consider that these dimensions should be addressed transversally, providing a better overall evaluation.
Quality of Health Web Sites: Dimensions for a Wide Evaluation
The use of a methodology for the evaluation, comparison and quality improvement of Health Web Sites is justified by its widespread adoption and visibility to Internet users. Due to the sensitiveness of their content and impact on users, health related sites should be evaluated. This chapter proposes three different dimensions for the development of quality evaluation methodologies of Health Web Sites: contents, services and technical. We consider that these dimensions should be addressed transversally, providing an integrated and better overall evaluation.

With the exploding growth of the web, health websites have become a dominant force in the realm of health care. Technically savvy patients have been using the web not only to self inform but to self diagnose. In this paper we examine the trust relationship between humans and health websites by outlining the existing literature on trust in health websites. A total of forty-nine papers were examined using a meta-analytical framework. Using this framework, each paper was coded for the antecedents and facets that comprise user trust in health websites. Our findings show that there is little consensus regarding the defining characteristics of the construct of trust in health websites. Further research in this field should focus on collaboratively defining trust and what factors affect trust in health web sites.
A framework for developing better instruments to measure web based health information quality
2010
With the Internet becoming a growing source of health information, evaluating the quality of the webbased health information is essential. A number of consumer-oriented instruments were designed to assess the quality of health information. However, existent tools are incomprehensive, unvalidated, not easy to use, and difficult to understand. The main objective of this study is to provide a framework for systematically developing validated and usable instruments to evaluate the quality of web-based health information. The framework incorporates item-to-total correlation and factor analysis. Next, weighting scores for the quality criteria are assigned based on the application of the Kano model to classify quality criteria as basic, performance or attractive. The development process ends with testing the instrument in terms of its usability, readability, reliability and validity. Among the implications and contributions of this research is improving the quality of the evaluation instru...
