Videos from Short-video Sharing Platforms as Source of Information on Colorectal Polyps: Cross-Sectional Content Analysis Study
ABSTRACT
Background:
TikTok has demonstrated huge potential in disseminating health information in recent years. However, to our knowledge, no study has examined information about colorectal polyps on TikTok.
Objective:
This study aimed to evaluate the quality and reliability of colorectal polyps-related videos on TikTok.
Methods:
The term “colorectal polyps” (in Chinese) was used to search on TikTok, then the information of the top 200 videos was extracted. The Journal of American Medical Association (JAMA) score, the Global Quality Scale (GQS), and the modified DISCERN were used to evaluate the content and quality of selected videos by two independent researchers.
Results:
192 eligible videos were included for further analysis, which mainly conveyed treatment-related knowledge (78, 40.6%), and disease knowledge (65, 33.9%). Most videos were uploaded by physicians (181, 94.3%). These videos had a median JAMA score of 2 (1-3), GQS score of 3 (1-4), and modified DISCERN score of 3 (1-4). The JAMA scores of videos uploaded by physicians were higher than videos uploaded by non-physicians (P<0.001). The collections of videos about post-treatment considerations were more than other contents (P=0.039). There was a positive correlation between the number of likes, comments, collections, and shares. The duration was positively correlated with the GQS scores (r=0.328, P<0.001), and the number of fans was positively correlated with the JAMA scores (r=0.176, P=0.015).
Conclusions:
There are numerous videos about colorectal polyps on TikTok, but the quality and reliability of these videos still need to be improved. It is necessary to establish a stricter mechanism to audit videos regarding healthy information on TikTok. Clinical Trial: Not applicant
