Methodology Notes

The National Quality Health Website Survey evaluates a sample of health web sites, representative of most- and least- visited websites (list of eligible "Health and Medical" -related web sites generated by the Internet traffic monitoring service Alexa).

Changes Between HP2010 and HP2020
This objective differs from Healthy People 2010 objective 11-4g in that the wording of the two objectives differs slightly. The Healthy People 2010 objective speaks to assessing the quality of health websites while this objective speaks to assessing the reliability of the information on the websites.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch

The original baseline was revised in 2013 from 51.9 to 47.9 percent of health-related websites that meet three or more evaluation criteria for disclosing information that can be used to assess information reliability due to a change in the data collection methodology. The Internet traffic monitoring service Hitwise was used to draw the original 2009 sample of websites. The revised sample was drawn using the Internet traffic monitoring service Alexa. (While Alexa is similar to Hitwise there are minor differences in sample size and websites sampled.) The target was adjusted from 57.1 to 62.2 percent to reflect the revised baseline using the new target setting method of minimal statistical significance.
