Clinical group supervision has existed for over 20 years in nursing. However, there is a lack of studies about the role of supervision in nursing students’ education and especially the focus on ethical reasoning.

The aim of this study was to explore and describe nursing students’ ethical reasoning and their supervisors’ experiences related to participation in clinical group supervision.

The study is a qualitative interview study with interpretative description as an analysis approach.

A total of 17 interviews were conducted with nursing students (n = 12) who had participated in clinical group supervision in their first year of nursing education, and with their supervisors (n = 5).

The study was based on the ethical principles outlined in the Declaration of Helsinki, and permission was obtained from the Regional Ethical Review Board in Sweden.

The analysis revealed that both the form and content of clinical group supervision stimulated reflection and discussion of handling of situations with ethical aspects. Unethical situations were identified, and the process uncovered underlying caring actions.

Clinical group supervision is a model that can be used in nursing education to train ethical reflection and to develop an ethical competence among nursing students. Outcomes from the model could also improve nursing education itself, as well as healthcare organizations, in terms of reducing moral blindness and unethical nursing practice.
