Evaluating the readability, understandability, and quality of online materials about chest pain in children

An increasing number of individuals use the Internet to obtain health information. However, online health information is unregulated and highly variable. We aimed to assess the readability, understandability, and quality of online information available for “chest pain in children.” This analysis was performed in January 2020, by inputting the search term “chest pain in children” into Google. The 180 search results were evaluated/categorized. The readability was assessed using the Flesch reading ease score, the Gunning FOG readability score, the Flesch–Kincaid grade level, the Coleman–Liau score, the Simple Measure of Gobbledygook readability score, the Fry readability score, and the automated readability index (ARI). The quality was assessed through the Journal of the American Medical Association (JAMA) benchmark criteria. The understandability was evaluated by the Patient Education Materials Assessment Tool (PEMAT) for this study. Sixty-five websites were analyzed (academic and hospital websites (n = 30), physicians and health information websites (n = 35)). Among all websites, the average reading grade level was 9.99. There was no statistical difference between the two groups for the average readability level (p: 0.645). The mean PEMAT score for all websites was 65.09%. There was no statistical difference between the two groups for the average PEMAT score (p: 0.945). For both groups, the understandability score was below 70%. The average JAMA benchmark score was 2.43 ± 1.06, with a statistically significant difference between the academic and hospital websites (2.07 ± 0.91) and physician and health information websites (2.74 ± 1.09, p: 0.009).
