Objectives: Confidence is essential in performing midwifery care since the profession places great demands on the ability to work independently with a scientific approach and professional responsibility. Clinical training is extensive during midwifery education and is essential for the development of midwifery student’s confidence and competence. The aim of the study was to describe the factors that increased and decreased confidence for midwifery students in clinical practice. Study design: A qualitative design was used. Data was collected by a questionnaire that measured Swedish studentsâ self-reported assessment of selected midwifery competencies. Two open questions gave the students the possibility to comment on what affected confidence during clinical practice. There were 401 comments analyzed by manifest content analysis. Results: Five categories described the experience of the students. Supervision during clinical training and the relationship with the midwives were most important factors for developing confidence. Further, to be theoretically and practically prepared before entering clinical practice. Regardless of activity the environment has to be learning and give time for reflection. Personal factors could affect professional confidence but above all it takes time to learn and practice midwifery. Factors that decreased confidence were stressed and uninterested supervisors. Patronizing attitudes towards students and the fear of doing something wrong also decreased confidence. Conclusions: Several factors contributes to enhance confidence among midwifery students in clinical training. The most important factor was supervision and the role as supervisor must be emphasized and sufficient time must be allocated to supervising midwives for them to fulfil their commitment.
