The main aim of this manuscript was to present a preliminary verification of the relations between the Dark Triad of personality traits and health-oriented behaviors in university students. The study involved 143 healthy students (94 female and 49 male) from the Silesian Voivodeship (Poland). The diagnosis of the elements of the Dark Triad of personality was carried out using a psychological examination based on the following tests: TriPM-41, Mach IV, NPI. The intensity of the health behaviors was examined using the Health Behavior Inventory developed by Z. Juczyński. The Health Behavior Inventory is positively correlated with narcissism and its self-sufficiency component and negatively with psychopathic disinhibition. For the Health Behavior Inventory's subscales, a positive relationship was observed between Positive Mental Attitude and narcissism, most of its components, and psychopathic boldness. The analysis of correlations with the division of the subjects into the Dark Triad traits ≤Me and >Me revealed that a significant positive correlation between the general intensity of the health behaviors and the intensity of narcissism mainly concerns university students with a lower level of this trait and its components. Therefore, it can be presumed that narcissism, although considered as a socially aversive trait, is associated with pro-health behaviors.
