The aim of this study is to examine the influence of nurses' self-concept (NSC) on clinical decision-making (CDM) among nursing students and hospital nurses. A further aim is to examine whether there is a difference in CDM and NSC between hospital nurses with various levels of experience and nursing students. A cross-sectional study was conducted during 2018 in the Faculty of Dental Medicine and Health and the University Hospital Center, in Osijek, Croatia, EU. The respondents consisted of 568 hospital nurses, and 129 BSc nursing students. Data were collected with the clinical decision-making in nursing scale (CDMNS) and the nurses' self-concept questionnaire (NSCQ). There was no correlation between CDM and NSC in either students or hospital nurses. Hospital nurses generally had significantly higher scores in CDM than nursing students. On the other hand, students had a significantly higher total NSC level. The results of this study suggest that experience has a positive impact on nurses' CDM skills. The high NSC estimated by students enables them to easily take up their clinical roles and approach the patient in a holistic manner, which is an attitude that gradually develops during studies and with clinical experience.
