Abstract:

Objective To understand the influencing factors of short video science popularization on the public’s willingness to perform cardiopulmonary resuscitation，thereby providing the basis for a more accurate short video science popularization education in the future. Methods By using purposive sampling method，16 short video users were selected as interviewee. Based on elaboration likelihood model，the interview outline was used to conduct semi-structured depth interviews. After the interviews，Colaizzi data analysis method was used to analyze and extract data. Results The influencing factors of short video science popularization on the public’s willingness to perform cardiopulmonary resuscitation could be summarized into 2 themes and 6 sub-themes. Video quality is the core factor that affects the willingness to rescue：the suspense and interest at the beginning of the video are necessary prerequisites for stimulating the willingness to rescue；the operability of the video is a source of self-efficacy that enhances the willingness to rescue；the pace of the video is an important factor that affects users’ ability to learn skills and enhances their willingness to rescue；relevant legal knowledge in the video is a reliable way to reduce rescuers’ concerns and increase their willingness to rescue. Information source quality is a external factor affecting the willingness to rescue：the platform’s penetration rate affects the spread of the video and the degree of user acceptance，promoting the willingness to rescue；the credibility of the source affects users’ emotional and cognitive responses，creating an immediate effect on the willingness to rescue. Conclusion This study actively expands the scope of information-based popular science education and supports health education initiatives on cardiopulmonary resuscitation in the new media era. It should emphasize the combination of core and external factors influencing short video science popularization，and enhance the quality of short video content，which will significantly boost the public’s willingness to engage.
