Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact firstname.lastname@example.org.
YouTube as a Source of Information on COVID-19: A Pandemic of Misinformation?
30 Pages Posted: 20 Apr 2020More...
Background: The COVID-19 pandemic is the 21st century’s largest public health emergency and its successful management relies on communicating factual information to inform public behaviour. As a social media platform with billions of daily views, YouTube has tremendous potential to both support and hinder public health efforts. However, the usefulness and accuracy of most viewed YouTube videos on COVID-19 have not been investigated.
Methods: Three reviewers coded the source, content, and characteristics of the 150 most viewed YouTube videos on COVID-19. The primary outcome was usability and reliability of videos, analyzed using COVID-19 Specific Score (CSS), modified DISCERN (mDISCERN), and modified JAMA (mJAMA) scores.
Findings: Of 150 videos screened, 69(46%) were included, totalling 257,804,146 views. Nineteen(27·5%) contained non-factual information, totalling 62,042,609 views. Government and professional videos contained only factual information and had higher CSS than consumer (mean difference [MD] 2·21,95% CI 0·10-4·32,p=0·037); mDISCERN scores than consumer (MD 2·46, 95%CI 0·50-4·42,p=0·008), internet news (MD 2·20, 95%CI 0·19-4·21,p=0·027), and entertainment news (MD 2·57, 95%CI 0·66-4·49,p=0·004); and mJAMA scores than entertainment news (MD 1·21, 95%CI 0·07-2·36; p=0·033), and consumer (MD 1·27, 95%CI 0·10-2·44,p=0·028). However, they only accounted for 11% of videos and 10% of views.
Interpretation: Over one-quarter of most viewed YouTube videos on COVID-19 contained misleading information, reaching millions of viewers worldwide. As the current COVID-19 pandemic worsens, public health agencies must better utilize YouTube to deliver timely and accurate information and to minimize the spread of misinformation. This may play a significant role in successfully managing the COVID-19 pandemic.
