Readability of Online Materials Related to Vocal Cord Leukoplakia

Abstract

Objectives: To assess readability and understandability of online materials for vocal cord leukoplakia. Study Design: Review of online materials. Setting: Academic medical center. Methods: A Google search of “vocal cord leukoplakia” was performed, and the first 50 websites were considered for analysis. Readability was measured by the Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), and Simple Measure of Gobbledygook (SMOG). Understandability and actionability were assessed by 2 independent reviewers with the PEMAT-P (Patient Education Materials Assessment Tool for Printable Materials). Unpaired t tests compared scores between sites aimed at physicians and those at patients, and a Cohen’s kappa was calculated to measure interrater reliability. Results: Twenty-two websites (17 patient oriented, 5 physician oriented) met inclusion criteria. For the entire cohort, FRES, FKGL, and SMOG scores (mean ± SD) were 36.90 ± 20.65, 12.96 ± 3.28, and 15.65 ± 3.57, respectively, indicating that materials were difficult to read at a >12th-grade level. PEMAT-P understandability and actionability scores were 73.65% ± 7.05% and 13.63% ± 22.47%. Statistically, patient-oriented sites were more easily read than physician-oriented sites (P
