Popular science and education of cosmetic surgery in China: Quality and reliability evaluation of Douyin short videos

Abstract

AbstractBackgroundDouyin APP is the short video APP with the largest number of users in China.ObjectiveThis study aimed to evaluate the quality and reliability of short videos about cosmetic surgery on Douyin.MethodsIn August 2022, we retrieved and screened 300 short videos related to cosmetic surgery from Douyin, extracted basic video information, encoded the content and identified the video source. The quality and reliability of short video information were evaluated using the DISCERN instrument.ResultsA total of 168 short videos of cosmetic surgery were included in the survey, and the video sources included personal accounts and institutional accounts. Overall, the total proportion of institutional accounts (47/168, 27.98%) is significantly less than that of personal accounts (121/168, 72.02%); nonhealth professionals received the most praises, comments and even collections and reposts, while for‐profit academic organizations or institutions received the least. The DISCERN scores of 168 short videos of cosmetic surgery were 3.74–4.58 (average 4.22). Content reliability (p = .04) and overall short video quality (p = .02) are significantly different, but short videos published from different sources have no significant difference in treatment selection (p = .052).ConclusionThe overall information quality and reliability of short videos about cosmetic surgery on Douyin are satisfactory in China.Patient or Public ContributionThe participants were involved in developing research questions, study design, management and conduct, interpretation of evidence and dissemination.
