Most of the existing health information quality studies have conducted professional quality evaluation from the perspective of professional researchers, but there are few studies has been conducted on the information quality perceptions from the perspective of ordinary users. This paper aims to explore the development of user's health information quality perception behavior and the factors influencing it in the short video platform. This paper collected subjective data on health information quality perceptions from 26 typical users by Critical Incident Technique and Focus Group Interviews, and conducted open coding on these data. The researchers sorted out 13 key nodes and 3 main stages of health information quality perception from 39 critical incident, and extracted 19 influencing factors in 4 dimensions from the remaining interview data. On this basis, an integrated model of health information quality perception in short video platforms was constructed. The model comprehensively demonstrated the complete process of users' health information quality perception, clarified the basic elements involved in quality perception activities and the details of interactions between elements, and revealed the influencing factors of quality perception.
