YouTube as a source of information on breast cancer-related lymphedema exercises: A content, quality, and reliability analysis.

This descriptive study aimed to determine the content, quality, and reliability of YouTube videos on breast cancer-related lymphedema exercises. A total of 127 videos were independently assessed, with 103 of them categorized as either informative or misleading content groups. The content (mean score: 4.07 ± 2.29) and quality (mean score: 3.15 ± 1.46) of videos concerning lymphedema exercises were moderate, while reliability (mean score: 2.27 ± 1.64) was low. Among the 103 videos categorized using the content checklist, Global Quality Scale, and DISCERN reliability instrument, 57.3% (n = 59) were informative, and 42.7% (n = 44) had misleading information. The mean scores of the content, quality, and reliability of the informative content videos were substantially higher than the misleading content videos, and of videos uploaded by universities/professional organizations/health care professionals/medical advertisements were higher than the videos uploaded by other sources. Through this study, the researchers have unveiled that the content and quality levels of YouTube videos in lymphedema exercises were moderate, and the reliability level was low.
