A quality analysis of pancreatic neuroendocrine tumors videos available on TikTok and Bilibili: Content Analysis
ABSTRACT
Background:
It is an innovative and highly efficient approach for disseminating knowledge about diseases through concise videos on various platforms. However, it remains uncertain whether the pancreatic neuroendocrine tumors (pNET) related videos available on current short video platforms can effectively convey accurate and impactful information to the general public. Our study aims to evaluate the information quality of Chinese short videos on pNET shared on the TikTok and Bilibili short video-sharing platforms.
Objective:
Our study aims to extensively analyze the quality of pNET-related videos on TikTok and Bilibili, intending to enhance the development of social media to provide the general public with more comprehensive and suitable avenues for accessing pNET-related information.
Methods:
A total of 168 qualifying videos pertaining to pNET were scrutinized from the video-sharing platforms Bilibili and TikTok for evaluation and scrutiny. Initially, the fundamental information conveyed in the videos was documented. Subsequently, we discerned the source and content type of each video. Following that, the Global Quality Scale (GQS) and Modified DISCERN (mDISCERN) were employed to appraise the educational value and quality of each video. A comparative evaluation was conducted on the videos obtained from these two platforms.
Results:
The number of pNET videos has seen a significant increase since 2020, with 9 videos in 2020, 19 videos in 2021, 29 videos in 2022, and 106 videos in 2023. There was no significant improvement in the mean GQS and mDISCERN scores from 2020 to 2023, which were 3.22 and 3.00 in 2020, 3.33 and 2.94 in 2021, 2.83 and 2.79 in 2022, and 2.78 and 2.94 in 2023, respectively. The average quality scores of videos on Bilibili and Tiktok were comparable, with GQS and mDISCERN scores of 2.98 vs 2.77 and 2.82 vs 3.05, respectively. The source and format of the videos remain independent factors affecting the quality scores. Videos that are uploaded by professionals (HR = 7.02, P = .002) and recorded in specialized popular science formats (HR = 12.45, P < .001) tend to exhibit superior quality.
Conclusions:
This study demonstrates that the number of short videos has increased dramatically in recent years, but the video quality has not improved significantly. The comprehensive analysis shows that source and format of videos are independent factors affecting video quality, which provides potential improvement measures for the improvement of short video quality.
