The deleterious effect of dating violence motivates the empirical exploration of the influential factors that may be targets of prevention. The aims of this study are to investigate violence in couples of university students and explore their relationship with jealousy and other correlates. Method: with a cross-sectional design, we surveyed 84 medical students from the National University of La Plata, Argentina. The instruments used were the Conflict in Adolescents Dating Relationships Inventory, the Multidimensional Jealousy Scale and the DSM 5 Cross-cutting level 2: Substance use and ad hoc items. Results: The scores of violence were generally low, with predominance of emotional verbal violence indicators and a similar pattern in both sexes. The total jealous scores had a normal distribution and were significantly related to intimate partner violence. The manifestations of jealousy with greater prevalence were emotional, especially in women. The valuation of own and foreign fidelity and the consumption of marijuana were significant correlates.
