Background: The shared decision-making model has been proposed as the ideal treatment decision-making process in medical encounters. However, the decision to participate in clinical trials rarely involves shared decision-making. In this study, we investigated the perceptions of Japanese clinical research coordinators who routinely support the informed consent process. Methods: This study aimed to (1) identify clinical research coordinators’ perceptions of the current status of shared decision-making implementation and its influencing factors, and (2) obtain suggestions to enhance the shared decision-making process in clinical trials. A cross-sectional survey was conducted using a web questionnaire based on the Theory of Planned behaviour. Invitations were sent to 1087 Japanese medical institutions, and responses from the participants were captured via the web. The shared decision-making process in clinical trials was defined according to the Shared Decision-Making Questionnaire for Doctors. The effect of the attitudes toward shared decision-making, clinical research coordinators’ subjective norms towards its implementation, perceived barriers to autonomous decision-making, and the number of difficult steps in the shared decision-making process on the shared decision-making current status as the shared decision-making intention was assessed by multiple regression analysis. Results: In total, 373 clinical research coordinators responded to the questionnaire. Many believed that they were already implementing shared decision-making. Attitudes toward shared decision-making (t = 3.400, p
