Assessing the readability and quality of online information on benign paroxysmal positional vertigo.

INTRODUCTION: Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo. It can have a significant impact on quality of life, with individuals often seeking information online for reassurance and education. The aim of this study is to assess the readability and quality of online information on BPPV.

METHODS: The terms 'benign paroxysmal positional vertigo' and 'BPPV' were entered into Google. The first 50 websites generated for each search term were screened. Readability was assessed using the Flesch-Kincaid Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG) Index and Gunning Fog Index (GFOG). Quality was assessed using the DISCERN instrument. Spearman's correlation between quality and readability was calculated.

RESULTS: A total of 39 websites met the inclusion criteria. The mean and 95% confidence intervals for the FRES, FKGL, SMOG, GFOG and DISCERN scores were 50.2 (46.1-54.3), 10.6 (9.87-11.4), 10.1 (9.5-10.7), 13.6 (12.7-14.4) and 36.7 (34.6-38.7), respectively. Weak correlation was noted between DISCERN and FRES ( rs = -0.23, p = 0.17).

CONCLUSION: Online information on BPPV is generally of poor quality and low readability. It is essential that healthcare professionals inform their patients of this limitation and advocate for improved online patient education resources that are both high quality and easy to comprehend.
