Context. One of the challenges in requirement engineering is the ability using survey as a requirement-engineering tool towards the software to refine user’s requirements. For instance, with the development of the way of healthcare, many advances in technology transformed the way of healthcare. E-health application is one of the technologies. As more and more health information that is stored electronically, e- health applications have given rise to trust issue in the area of data sharing. Identified the relationship between trust and data sharing based on the survey method is a valid approach, but the current studies still do not give a definite guideline about how requirement engineering should use a survey method step-by-step to refine the needs of users’ trust into software attributes. Based on the mentioned situation in e-health, defining a method to design survey to elicit requirements is needed. Objective. In this paper, the aim of the study is to design a survey method for refining user’s requirements of trust in requirement engineering based on the current state-of-art. The paper present the research on data sharing in e-health application. Methods. This study presented an action research, which identified the way about how to refine user’s requirement of trust. Survey was the main approach to do investigation among the e-health applications. Three cycles of AR were conducted in this paper, and three versions of questionnaires were designed in the research process in order to identify the factors that affected user’s trust in data sharing in e-health applications. Results. Through the action research, I found out three factors that affected user’s trust in data sharing, then the factors were identified, analysis and summarized, and the relationship between trusts and the factors is describe based on analysis results of the collected data, which obtain from the improved questionnaires. To find out the relationship between trust and the factors help present the process that how to design an accurate survey to refine user’s requirements. Based on the process and results of the action research, the survey guideline to refine user’s requirements of trust is designed and described. Conclusions. Based on the results that obtained in this study, I designed a preliminary survey guideline for refining user’s requirements of trust. This study will help requirement engineering to elicit requirement of trust in e-health based on a new and specific survey method.
