Criteria for Assessing the Quality of Health Information on the Internet

APHA Action Board Implementation Plan
Resolution #200031 Submitted September 19, 2002

The Action Board "Health Information on the Internet Work Group" has prepared an implementation plan, described below, for Resolution #200031: Criteria for Assessing the Quality of Health Information on the Internet (Attachment 1). The resolution was rated among the top five resolutions in 2000 by the APHA Governing Council. The implementation plan is built on the premise that APHA should take a leadership role in promoting quality standards for health information on the Internet. Not satisfied with merely creating the plan, the Work Group took steps to implement key parts of it. To educate APHA members on this important issue, member Karyn Pomerantz submitted a session abstract which was accepted for the 2002 meeting entitled "Providing Health Information to the Public". The session (#3145.0) will occur on Monday at 12:30pm in the Technology Center. The Work Group wrote an article entitled "Evaluating Health Information Websites" (Attachment 2) intended for placement on the APHA website and wide distribution to APHA partners (see Stakeholder list below). The article identifies several Web-based tutorial programs in English and Spanish that should be helpful to seekers of health information. The editor of the Nation's Health has agreed to publish an article about the topic and the Work Group's report in an upcoming issue, hopefully the November issue. The Work Group also encourages APHA to join with other stakeholders to advocate quality standards for health information provided on the Internet.

Resolution 200031: Criteria for Assessing the Quality of Health Information on the Internet

The American Public Health Association,

  • noting that in 1998 more than 22 million Americans went to the Internet for health-related answers, and expecting this number to grow to 33.5 million in 2000;1 and
  • Finding that nearly 70 percent of those searching for health care information on the Internet did so before visiting a doctor's office;2 and
  • Realizing that the Internet can be a valuable resource for users seeking health information and presents a powerful mechanism for helping users improve their health care decision-making by providing easy and rapid access, exchange, and dissemination of enormous amounts of health information; and
  • Acknowledging that the quality of health information is critically important, as it could potentially affect health outcomes for millions; and
  • Understanding that the quality of health information on the Internet is extremely variable and difficult to assess; and
  • Recognizing that health information is proliferating on the Internet and that there is a growing need for objective, reproducible, widely accepted criteria that can be used to evaluate the quality of the information; and
  • Building on APHA's long-standing commitment to accurate health education (Resolution 7320 and Position Paper 7742), especially on controversial topics (Resolution 85248) on APHA's long-standing belief in preventing health fraud through provision of accurate health information (Resolution 88139), and on APHA's long-standing concern with the role of the electronic media health education (Resolutions 520210 and 762211); and
  • Aware that as of June 24, 1999, the United States Federal Trade Commission had found 800 Internet sites containing inaccurate health claims, and undertook settlements with four businesses accused of deceptively marketing health products on the Internet; and
  • Noting that incidents relating to health-related websites demonstrated the blurring of lines between objective information, advertising, pro-motional content, and proper disclosure;3 and
  • Highlighting the time-sensitive nature of this issues; and
  • Understanding that users must be made aware of the potential for misinformation and recognize the critical need to assess the quality of the information provided; and
  • Discerning that the choice of appropriate evaluation criteria for the information is crucial and that no uniform guidelines for quality assessment of Internet-based health information existed until the Health Summit Working Group produced the policy paper,4 Criteria for Assessing the Quality of Health Information on the Internet;5 and
  • Recognizing that the Health Summit Working Group selected, defined, ranked, and evaluated seven major criteria for assessing the quality of Internet health information: credibility, content, disclosure, links, design, interactivity, and caveats (advisories); and
  • Observing that content providers must be encouraged to develop and post high-quality information, and policymakers and health care professionals must be educated on this important health issue;


  1. Urges individuals and organizations to be-come involved in promoting the application of appropriate criteria for assessing health information on the Internet, whether it be
    • Educating consumers and health care professionals on how to evaluate Internet health information,
    • Using criteria to develop their own Internet health site, or
    • Promoting the use of educational tools to help assess quality;
  2. Supports continued FTC monitoring and enforcement of fraudulent health claims and deceptive health marketing on the Internet;
  3. Endorses the development, publication, and dissemination of criteria for evaluating Internet health information that address such items as those defined by the Health Summit Working Group:
    • Credibility: includes the source, currency, relevance/utility, editorial review process for the information, and financial disclosure,
    • Content: must be accurate and complete, and appropriate disclaimer provided,
    • Disclosure: includes informing the user of the purpose of the site, as well as any profiling or collection of information associated with using the site,
    • Links: evaluated according to selection, architecture, content, and back linkages,
    • Design: encompasses accessibility, logical organization (navigability), and internal search capability,
    • Interactivity: includes feedback mechanisms and means for exchange of information among users,
    • Caveats: clarification of whether the site's primary function is to market products and services or to serve as a primary information content provider.

Evaluating Health Information Web Sites*
Health information is one of the most popular topics on the Internet. People search for answers to many health questions, including "Why don't I feel well?" "What are these symptoms?" "Which treatment is the best and safest for me?" "How can I stay healthy and eat right?" "How do I lose this weight?"

Reading different points of view of the Internet can help us form questions to ask our health care providers and lead us to new solutions. However, we all need to make sure the information we use to make decisions about our health-and our family's health-is reliable. For example, we need to make sure the information does not advise us to try harmful medicines or follow unhealthy diets. The problem is, anyone can post health information on the Internet. There are ways to protect yourself and increase your chances of finding reliable information. You can look for organizations you trust that sponsor Web sites. You can look at more than one Web site and read different points of view.

Here are some easy, basic questions to ask yourself. Use them to help you decide if the Web site is one you can rely on for accurate and useful information.

  • Does the Web site sponsor provide or write the information? The sponsor should be someone you consider a reliable source.
  • Does the site have names and contact information for the sponsors or authors?
  • Does the sponsor or author have a health background? Look for their credentials (degrees, work experience, books they've written). Are they telling a personal story, or is it hard to tell?
  • Does the sponsor or author seem to be trying to sell you something?
  • Has someone you trust recommended this site? Have you talked with a health professional about this site or about information you've obtained from this site?

*This article is intended to be a drop-in for newsletters, fliers, Web sites, or other communication materials. It can also be the basis for developing more extensive guidance for Internet information seekers. The article was developed by the APHA Action Board Work Group on "Criteria for Assessing the Quality of Health Information on the Internet." The listing of Web sites does not imply endorsement of any particular Web site by the American Public Health Association.

  • Does the Web site get its information from reliable sources? Does it make outrageous claims, or is it hard to tell?
  • Does it provide references for the information? Is it someone's opinion, or is it hard to tell?
  • Does it include a broad range of information (both the pros and cons)?
  • Is there information about different ways to improve your health? You may need to look at more than one Web site to support the information you've found, or to learn about different ways to improve your health.
  • Is the information well organized and presented?
  • Is it easy to navigate and easy to read? Does the Web site use words you understand? Will you be able to ask someone to explain the information to you if you don't understand it?
  • Does it protect your privacy? Can you tell how? Can you search for information without giving personal information?
  • Can you follow the links? Do they work?
  • Are there useful definitions or pictures to help make the information clear?
  • Can you tell when the information was written and the site updated? Health information frequently changes.
  • Is the information current and appropriate?

A Quick Checklist: What To Look For

  • A clear purpose
    ***If you cannot check off the majority of these items, you may want to think twice about using this Web site and look for another source.***
  • Names of the sponsors and authors of the information
  • Useful, easy to understand information
  • Specific answers to your questions
  • Links that work
  • Dates to make sure the information is current
  • Privacy protections
