BackgroundBecause of the wealth of information available on the internet and increasing numbers of individuals relying on websites as a primary source of information for health-related questions, it is important that the readability of their content is within the comprehension level of most readers.ObjectiveThe study evaluated the quality and readability of English-language Internet information for tinnitus.Research DesignAnalysis of Internet websites on tinnitus.Study SampleA total of 134 websites with tinnitus information.Data Collection And AnalysisThree key words (i.e., tinnitus, ringing in the ear, and buzzing in the ear) were entered in five country-specific versions of the most commonly used internet search engine in August 2016. For each of the 15 searches, the first 20 relevant websites were examined. After removing duplicates, a total of 134 websites were assessed. Their origin (commercial, nonprofit organization, government, personal, or university), quality (Health On the Net [HON] certification and DISCERN scores), and readability (Flesch Reading Ease score, Flesch-Kincaid Reading Grade Level Formula, and Simple Measure of Gobbledygook) were assessed.ResultsMost websites were of commercial (49.3%) or nonprofit organization (38.8%) origin. Their quality and readability was highly variable. Only 13.5% of websites had HON certification. χ² analysis showed that there was significant association between website origin and HON certification [χ²(4) = 132.9, p < 0.0001]. The mean DISCERN scores were 2.39. No association between DISCERN scores and website origin was found. Readability measures showed that on average, only people with at least 10-12 yr of education could read and understand the internet information for tinnitus in websites. Almost all the websites exceeded the most stringent reading level recommended for health information.ConclusionsThe results highlight great variability in the quality and readability of health information, specifically for tinnitus in the internet. These findings underscores the need for stakeholders (e.g., web-developers, clinicians) to be aware of this and to develop more user-friendly health information on websites to make it more accessible for people with low literacy.American Academy of Audiology.
