Abstract :Aims: Health-related videos on YouTube make it easy to share information on diseases and address a wide audience. However, there is doubt among specialists about their reliability, quality, and whether they contain correct information. The present study aimed to evaluate the quality of the information provided by searching for “aphasia” on YouTube™. Methods: The results of the YouTube™ search were examined using the keywords “aphasia, Broca, Wernicke, conductive type, transcortical, anomic”. A total of 100 videos were identified, containing at least one of the keywords, relevant to the context, having at least 1000 views, published after 2010, in the English language, and shorter than 60 minutes. Modified DISCERN, Global Quality Score insert ignore into journalissuearticles values(GQS);, Video Information and Quality Index insert ignore into journalissuearticles values(VIQI);, and the Journal of American Medical Association insert ignore into journalissuearticles values(JAMA);, rating, viewer interaction, and meta data were used for evaluating the videos. The scores of the scales indicated by The Kruskal-Wallis H Test were compared between the groups according to the video source insert ignore into journalissuearticles values(news agency, healthcare personnel/specialist, other people);. The data were analyzed with Dunn’s Test as a post-hoc test. Relational analyses and Spearman’s RHO Correlation were used for statistical analyzes. The significance level was taken as p<0.05 Results: A total of 59 videos were taken for assessment, 34% of the videos were uploaded by news agencies, 52.5% by healthcare institutions/specialists, and 13.5% by laypeople. Significant differences were detected between GQS scores insert ignore into journalissuearticles values(χ2=8.66, p=0.01); and VIQI insert ignore into journalissuearticles values(χ2=9.87, p=0.00); according to the video sources. Cohen Kappa scores indicating inter-observer agreement were 0.887. The average DISCERN score was 3.74, the VIQI score was 3.64 and GQS score was 3.67 and the JAMA score was 2.59. Conclusion: The videos about aphasia on YouTube™ were determined to have moderate scores in terms of quality, information accuracy, and reliability. Videos uploaded by healthcare professionals/specialists have higher quality and information accuracy. Especially the news agencies with the highest ratings should be sensitive about publishing accurate information.
