We searched videos on YouTube (www.youtube.com ) using the following keywords: “health resort medicine,” “spa treatment,” “spa therapy,” “hydrotherapy,” “thermal medicine,” “balneology,” and “balneotherapy” on June 17th, 2021. The first 50 videos were evaluated for each of the keywords (with a total number of 350) by two researchers (FDG, FBEF) specialized physicians in Thermal Spa Medicine. The videos that are digressive, irrelevant, duplicate, and in a language other than English were excluded.
The YouTube videos are supposed to be sorted by relevance. So, the most relevant videos are displayed at the top of the page. However, since the investigators (FDG, FBEF) live in different countries (Turkey and France), the featured videos are sorted into different lines. So, while watching the videos, we used the “screen share” option of the Zoom application and went over one screen to avoid confusion.
