Is the information about occupational health and safety on YouTube reliable for users?

Companies provide employees with occupational health and safety (OHS) training through videos on YouTube. In this study, the reliability of 118 YouTube videos related to OHS was evaluated by two experts using Journal of the American Medical Association (JAMA) and global quality score (GQS) scales. Six video variables - video duration, number of subscribers, likes, views, publication time and comments - were evaluated based on video source (five groups) and type (seven groups). The correlation analysis found a positive significant relationship between all variables except publication time-number of comments. Scores according to video source and type were 1.9 out of 4 on the JAMA scale and 2.3 out of 5 on the GQS scale. These scores show that the videos are inadequate and of poor quality. There was a statistically significant difference between video durations according to video type. Moreover, video sources differ depending on the number of subscribers and comments.
