The objective of this study was to assess the influence of an overseas medical service project on Taiwanese medical education. This study employs grounded theory for the analysis of the collected data, which consisted of the participating students' personal reports. After identifying certain medical-education-related themes in students' personal reports, the importance of these recurring themes was estimated according to the frequency of their appearance in the students' personal reports. It was concluded that five major themes could be identified: communication skills, cultural competency, global health-related knowledge, personal growth and interpersonal relationship development. Compared to the results published previously based on the experiences of Western .students, the authors conclude that overseas medical service has a similar positive influence on Taiwanese medical education as was found with Western medical education.
