Objective To explore the experiences of graduate nursing students in interaction with their supervisors, and to provide reference for improving the quality of graduate nursing education and building a harmonious student-supervisor relationship. Methods A descriptive qualitative research method was used to conduct semi-structured in-depth interviews with 15 nursing supervisors and 11 graduate nursing students. The interview data were analyzed by content analysis method. Results Two themes and five sub-themes were extracted:status of student-supervisor interaction (generally harmonious, student-supervisor gap should be bridged) and the influencing factors (individual′s ability and effort investment, consistency of expectations, and external conditions). Conclusion Student-supervisor interaction is relatively satisfactory, but still needs to be improved by enhancing individual′s ability, reaching consensus on expectations, and improving the external environment, so as to form a closer student-supervisor community.
