Background/Objectives: Growing concern about narcissistic traits in younger generations and their effects on empathy, communication, and mental health underscores the need for focused research on medical students as future healthcare professionals. Medical training carries a substantial psychological burden that can compromise students’ well-being, professional development, and the future quality of patient care. Personality traits, including grandiose and vulnerable narcissistic dimensions, may shape susceptibility to such psychological distress. Therefore, this study aimed to examine narcissistic traits and their associations with psychological distress among Croatian medical students across study years and trait levels. Methods: In this cross-sectional study, 413 medical students from the University of Split completed self-administered questionnaires during mandatory classes. Narcissistic traits were assessed using the Pathological Narcissism Inventory (PNI) and psychological distress was measured with the Brief Symptom Inventory (BSI). High pathological narcissistic traits were operationally defined as scores within the highest quartile. Statistical analyses included correlation, comparative, and regression analyses. Results: Overall, pathological narcissistic traits were expressed at low to moderate levels and did not differ across academic years. High narcissistic traits were identified in 35% of students, with 15% exhibiting elevated levels of both grandiose and vulnerable dimensions, suggesting an overlap between the two dimensions. Gender differences emerged across both narcissistic dimensions, with women scoring higher on vulnerable and men scoring higher on grandiose narcissism. One-quarter of students met the criteria for clinically significant psychological distress, which was more prevalent in the earlier years of study. High levels of pathological narcissistic traits, particularly vulnerable traits, were significantly associated with clinically significant distress and elevated symptoms across nearly all BSI domains, most notably interpersonal sensitivity and paranoid ideation. Despite this burden, only a minority of distressed students reported seeking psychological help. Conclusions: Elevated pathological narcissistic traits are significantly associated with psychological distress in medical students. The high prevalence of distress, combined with low help-seeking rates, underscores the need for early identification strategies and structured mental health support within medical education. Addressing personality-related vulnerability factors may improve student well-being, enhance professional development, and, ultimately, elevate the quality of healthcare delivery.
