Clearness qualitative comparative analysis of the spread of TikTok health science knowledge popularization accounts.

Abstract

This study analyzed the popularity of TikTok health knowledge popularization accounts with the objective of creating a template for accounts suited to widely disseminating information, thereby enhancing the public's access to health knowledge on a broader scale. This study is based on 40 Chinese TikTok short video accounts that were active from February to April 2022 and were engaged in health science popularization. Data were validated by structured calibration using three qualitative anchors. It employs the "content-context" and the elaboration likelihood models as the theoretical framework. A qualitative comparative analysis is used to explore the factors affecting the popularity of this type of account mechanism. Among the nine variables involved in the calculation, one reached 0.909091, demonstrating that the number of followers was both a necessary factor and a condition for the popularity of short health science video accounts. There were 16 paths in the complex solution with a consistency of 1, and their overall coverage reached 0.878788, indicating that approximately 87% of the cases could be explained. From the spread of the content and communication situation, professional medical knowledge, current hot topics, professionals, and serious issues were the most likely combinations for rapid spread. From the perspective of the central and edge paths, "likes" exceeding 100,000 and fans exceeding 1 million were essential combinations. The dissemination of medical knowledge has gained significant traction, especially with regard to trending and popular topics. When it comes to the tone of communication, a serious style proved effective in fostering what can be termed "hot communication." From the standpoint of central and peripheral paths, it is crucial that the number of likes in the past month and the total number of fans surpass 100,000 and one million, respectively.
