Background Previous research mainly focuses on how to support nursing students in caring for the patient and on educators’ views of students’ development as professional caring nurses. Against this background, it is important to further investigate nursing students’ perspectives on what it means to become a professional caring nurse. Research aim This qualitative systematic review study aims to identify and synthesize nursing students’ perceptions on the meaning of becoming a caring nurse. Research design and data sources Systematic data searches were (...) conducted by using the electronic databases MEDLINE (Ovid), CINAHL (EBSCO), Academic Search Premiere (EBSCO), and Philosopher`s Index. In total, 13 studies met the inclusion and quality criteria. The articles were analyzed by a systematic review and a thematic synthesis according to Thomas and Harden. Ethical consideration The study followed good ethical practice guidelines outlined in the Northern Nurses’ Federation. Findings The analysis resulted in eight descriptive themes and finally in three analytical themes: Becoming is to get in touch with one’s inner ethic or ethos, Becoming is a movement between courage, understanding, and being touched, and Becoming is strengthened through caring role models and a learning culture. Conclusions Becoming a professional caring nurse is seen as an ongoing movement toward a deeper understanding of oneself and one’s being and bearing. This movement is enabled when nursing students have a sense of self-awareness, courage to stand in their vulnerability, and reflect on their responsibility, caring attitude, and inner values and ethics. The force of becoming is that the attention is directed beyond self to care for and feel empathy for others in a caring manner. Becoming is released through a caring relationship, external confirmation, and good role models. A lack of external support in the movement can potentially prevent the students from becoming a professional caring nurse. (shrink)
