Aim of the study: The aim of this study was to examine the presence and characteristics of narcissism in medical students at the University of Split, then to examine the relationship between study groups in the prevalence of vulnerable and grandiose narcissism, and to investigate the incidence of vulnerable and grandiose narcissism by gender and year. Data sources and methods: Respondents were first and third year undergraduate students at OZS in Split. 101 first-year students and 100 third-year undergraduate students of the OZS in Split participated in the research. The study was conducted through an anonymous survey with the prior consent of the Ethics Committee of the University Department of Health Studies in Split. The questionnaire consisted of two parts: a self-assessment scale and questions with offered answers and questions with completion. In the first part of the questionnaire, the questions referred to the sociodemographic characteristics of the respondents (age, gender, years of study, previous traumatic experiences and psychological help). The second part was a validated PNI questionnaire, composed of 52 particles used to measure the two dimensions of pathological narcissism, grandiosity and vulnerability. Results: The results of this study showed that there was no difference in the expression of narcissistic personality traits between students of physiotherapy, medical radiology and medical laboratory diagnostics in relation to students of nursing and midwifery (Z = -.466; p = .641). The results also showed that there was no difference in the severity of grandiose narcissism between students of physiotherapy, medical radiology, and medical laboratory diagnostics compared to students of nursing and midwifery (t = 0.821; p = 0.207). Students of nursing and midwifery did not show more pronounced personality traits of vulnerable narcissism in relation to students of physiotherapy, medical radiology and medical laboratory diagnostics (Z = -. 373; p = .709). Narcissistic personality traits were not more pronounced among female students compared to female students (Z = -.303; p = .762). Vulnerable narcissism was not more pronounced in female students compared to male students (Z = -.091; p = .927). Grandiose narcissism was not more pronounced in male students than female students (t = .248; p = .244). Third - year students showed less pronounced traits of vulnerable and grandiose narcissism compared to first - year students (narcissistic personality traits Z = -.2977; p = .003; vulnerable narcissism Z = .2770; p = .006; grandiose narcissism t =. 065; p = .004). Conclusions: There were no differences in the expression of narcissistic personality traits, grandiose and vulnerable narcissism between all study groups. There were no statistically significant differences in the expression of narcissistic personality traits, grandiose and vulnerable narcissism by gender. Research has shown that the incidence of narcissism was lower in the higher years of study.
