  • Panel developed condition-related questions that one would expect to be answered by a site
    • “When should I start having regular mammograms?”

Reading grade level

  • English
    • Collegiate
  • Spanish
    • 10th grade


  • Consumers may have trouble finding complete and accurate information regarding a health problem
  • Consumers relying on the Internet to make treatment decisions, deficiencies in information might negatively affect decisions


  • Reading level is “quite high”
    • 48% of the overall population and
    • 75% of current welfare recipients have “low or very low” reading skills


  • Study limitations
    • Internet is a moving target
    • Small set of search engines
    • Simple search terms
    • Not a “natural experiment” with real people, real problems
    • Use of medical terms (rather than lay terms) in search strategy may have skewed results
    • Searchers may have missed important material


  • Variation among search engines suggest that overall search efficiency could be improved
  • Lack of critical information can be fixed
  • Information should be accurate and free of conflict of interest
  • Uniform rating scale would be of use
  • Information needs to more “readable” or reader friendly”

Consumer kids
