Objective To understand the influencing factors of information adoption intention of short videos on pharmaceutical science popularization,in order to provide theoretical guidance for improving the efficiency of users' adoption and utilization of pharmaceutical science popularization information and carrying forward the publicity of pharmaceutical science popularization.Methods Based on the United Theory of Acceptance and Use of Technology,this paper combines the Information Adoption Model and Perceived Risk Theory to construct a research model from three dimensions:subject,object,and environment.The data was collected through online questionnaires.The Partial Least Squares Structural Equation Modeling(PLS-SEM)approach was used to validate the research hypotheses and analyze the influence paths of the factors.Results A total of 443 valid questionnaires were collected.The R2 of performance expectancy and information adoption intention are 0.358 and 0.545,respectively,which means the model has good analytical power.Information quality(β=0.478,P＜0.01)and source credibility(β=0.162,P＜0.01)have a positive effect on performance expectancy.Performance expectancy(β=0.336,P＜0.01),effort expectancy(β=0.139,P＜0.01),facilitating condition(β=0.261,P＜0.01),and social influence(β=0.158,P＜0.01)have a positive effect on information adoption intention.Perceived risk(β=-0.006,P＞0.05)has no effect on information adoption intention.Conclusion The study found that the information quality and source credibility of short videos on pharmaceutical science popularization together positively affect users' performance expectancy,which indirectly affects information adoption intention.Performance expectancy,effort expectancy,facilitating condition,and social influence all have significant positive effects on information adoption intention.Perceived risk does not have a significant effect on information adoption intention.
