Abstract:

[Purpose/Significance] This paper aims to provide evidence synthesis crowdsourcing initiators with references to understand user participation behavior, propose and implement relevant behavioral intervention strategies, and guide and promote user participation. [Method/Process] A model of influencing factors of user participation intention was constructed based on the planned behavior theory (TPB), the technology acceptance model (TAM) and motivation theory. Hypotheses were also proposed. The relevant data of the sample objects were collected through a questionnaire survey, and the hypotheses were tested using a structural equation model. [Results/Conclusions] Evidence synthesis crowdsourcing itself is an academic, scientific and non-commercial task. In crowdsourced evidence synthesis, factors such as attitude, self-efficacy and trust significantly impact users' willingness to participate. The academic atmosphere has no significant impact on users' willingness to participate. Monetary rewards, recognition, and skill improvement have a significant positive impact on attitude, while perceived effort has a significant negative impact on attitude, and enjoyment of the activity has no significant impact on attitude. Attitude, self-efficacy, and trust directly influence willingness to participate, while monetary rewards, recognition, skill improvement and perceived effort indirectly influence willingness to participate through attitude. The order of influence of individual motivational factors on willingness to participate, from greatest to least, is as follows: skill improvement, recognition, and monetary rewards. The results show that, compared with monetary rewards, non-material factors are a more important driving force for users to participate in crowdsourced evidence synthesis. In terms of perceived behavioral control factors, efficacy is one of the main cognitive forces that guides users' willingness to participate. The degree of trust directly determines whether users are willing to learn about and participate in the project. Therefore, when organizing crowdsourcing activities and recruiting participants, as well as providing incentive measures, the crowdsourcing party should consider the following aspects: for potential target groups, online training opportunities, development of related learning resources, establishment of interactive feedback mechanisms, and an online community for timely communication can be provided. Participants can be provided with the opportunity to receive signatures, certificates or emails expressing appreciation and encouragement or other forms of recognition. Organizers can provide resources and support to reduce users' perceived burden. This can be done through examples such as organizing training and establishing communities. According to specific circumstances, appropriate monetary rewards can be provided to participants. Organizers should adopt strategies that improve users' self-efficacy, convey relevant information and provide assistance. To gain the trust of users and make appropriate commitments to protect their legitimate rights and interests, organizers are encouraged to provide detailed information about themselves, including the affiliation, research experience of the team and their academic achievements.
