Abstract
Objective:This study evaluated the quality of popular science videos on cerebral infarction on the TikTok platform,analyzed the completeness and scientificity of the content,and explored the correlation between video features and quality scores to optimize health education.Method:On September 14,2024,keywords such as"cerebral infarction OR cerebral embolism"were retrieved to obtain the top 200 videos.Eventually,177 videos were included for analysis.The structured content integrity scoring tool and DISCERN tool were used for multi-dimensional quality assessment,and the correlations between video duration,the number of likes,the number of comments,the number of collections,etc.and the quality score were analyzed.Result:The 177 videos received a total of 9,857,103 likes,471,631 comments,482,371 collections and 4,908,134 forwards.The DISCERN score showed that 93.2％of the videos had"average"or lower quality.The video duration was significantly positively correlated with the DISCERN score(P<0.001).There was no significant correlation between the interaction indicators and the quality score(P>0.05).Conclusion:The overall quality of popular science videos on cerebral infarction on the TikTok platform is relatively low.The video duration is a key factor affecting the quality.It is recommended to increase the video duration and the weight of professional content.关键词
