Introduction: Although the Internet contains many health Web sites with valid information, it also contains sites with false information.Objective: To learn whether high school students searching health care information believe they are using evidence-based sites and to understand their topics of interest, frequently navigated sites, and trust/confidence in the credibility of information found.Design: Cross-sectional.
Main Outcome Measures:Students at a private high school answered an anonymous survey inquiring about their belief that they were using evidence-based sites, topics of interest, search engines of choice, and their trust in information obtained. Descriptive statistics and multivariate analysis of variance were used to compare trends across grade levels.Results: Of 705 students enrolled, 24.7% were absent or declined to participate. For the remaining students, 497 completed the surveys, representing a response rate of 70.5% (497/705) and a participation rate of 93.6% (497/531). Overall, 82% of students communicated that they believed they were using evidence-based sources when searching for health information (p < 0.0006). Findings showed that 42% searched general health information, and 43% investigated specific medical conditions; topics related to skin and acne were researched significantly more often (p < 0.05). Overall, most students (80%) reported using Google as their number 1 search engine (p < 0.004), 38% reported using WebMD Search (p < 0.0002), and 50% of students used Wikipedia (not significant).Conclusion: Most students trust health information they learn from the Internet. We found it chilling that less than half of students obtained their information from a Web site with health care professionals' oversight.
