Abstract Objective: YouTube is one of the most visited social media websites in the world with a huge database. It is used frequently for information on diseases and symptoms. The purpose of this study is to analyze the content and reliability of the content of videos about vertigo on YouTube. Methods: A search was made on youtube using the keyword “vertigo”. After the exclusion of 81 videos, the remaining 69 videos were analyzed by two independent reviewers. Video demographics, content of videos, quality of content and reliability of information were evaluated using total content scoring (TCS), Global Quality Scale (GQS) and modified DISCERN for each video. A 9-point scale was used to assess the content of videos and the videos were classified as high- and low-content according to this scale. Results: Fourty six (66.7%) of the videos were included in the low-content group, while 23 (33.3%) were included in the high-content group. The mean TCS, GQS and modified DISCERN scores of the videos were 3.42, 2.48 and 2.09, respectively. There were significant positive correlations between GQS and total content score (r=0.873, p<0.001), between modified DISCERN and total content score (r=0.883, p<0.001) and between modified DISCERN and GQS (r=0.900, p<0.001). Conclusion: The results of this study show that the videos about vertigo currently featured on YouTube do not contain enough informational content. Most of the videos focus on maneuvers, and diagnosed patients may be advised to watch certain videos to learn how to perform the maneuvers.
