Social responsibility (SR) is a fundamental value among physicians, who must maintain a positive attitude toward it during medical education by providing community service. This study investigated the impacts of service learning-based social responsibility training (SRT) by evaluating the SR perceptions of medical students who had participated in an SRT program and their views on the impacts of SRT on themselves, their institution, and the studied target groups. Four focus group interviews were held with 32 medical students, following a determined purposeful sampling method. Guided by qualitative content analysis, the data were analyzed through an iterative coding process. The analysis of the students' perceptions of SR revealed 13 themes in the impact of SRT: 7 for medical students, 4 for the medical school, and 2 for the studied target groups. The students explained SR with concepts of responsibility, volunteering, sensitivity, kindness, and community orientation and believed that SRT practices based on service learning effectively deepen the understanding of SR and the needs of the target groups in which they work. Communication, teamwork, leadership, and project management skills were defined as students' achievements. SRT practices had a positive effect on the studied target groups by meeting their physical and emotional needs; furthermore, they increased their medical school's recognition and accountability in society. Therefore, providing service learning-based experiences with reflection opportunities throughout medical education supports the development of medical students' understanding of SR, which can be strengthened with a supportive corporate culture and by improving the faculty's role-modeling and tutoring skills.NEW & NOTEWORTHY Social responsibility is a fundamental value among physicians, who must maintain a positive attitude toward it during medical education by providing community service.
