This document provides guidance on how to evaluate the reliability of health information found online. It discusses how many Americans use the internet to research health topics but notes there are few regulations, so information cannot always be trusted. It outlines the "ABCs" of evaluation: accuracy, authority, bias, currency, and comprehension. Specific criteria are provided to assess websites based on these factors. Recommended reliable sources like MedlinePlus and Mayo Clinic are highlighted and their credibility is analyzed using the evaluation criteria. The objective is to help readers become informed health consumers by learning to critically evaluate online health information.

3. Did you know?
• A Pew Internet survey reported that 57% of
American adults use the Internet to find
healthcare information
• The most commonly-researched topics are
specific diseases or conditions; treatments or
procedures; and doctors or other health
professionals.
• A typical search for health information is on
behalf of someone else – information access by
proxy

4. About the Internet
• No one is in charge
• There are few rules and regulations
• Anyone can build a website
• No educational or professional
qualifications are necessary
• Therefore, you cannot automatically trust
information found on the Web

5. Remember the ABCs of evaluation
Accuracy
Authority
Bias
Currency
Comprehension
6. Remember the ABCs of evaluation
Accuracy
• Does the site provide references to scientific
literature? (popular media doesn’t count)
Authority
• Is the information from a credible source?
(check the About Us section and the site’s domain)
Bias
• Who pays for the site? Are ads/sponsored
content clearly labeled?
7. Remember the ABCs of evaluation
Currency
• Are there dates on the material? (under 5 yrs)
Comprehension
• Is the information understandable and the site
easy to navigate?
8. Warning
• Watch out for sites like
– WebMD.com
– Gerd.com
– DrKoop.com
• These sites and other like them may have
some reliable information, but their main
goal is not to educate the user but to
generate money
9. But how can I tell if a health
website is reliable or not?
10. Example website evaluation
• Mayo Clinic’s Healthy Aging center
– http://www.mayoclinic.com/health/healthy-
aging/MY00374
– This site is in the top results for a Google
search of senior health

evaluation criteria
