The aim of the research was to examine the relationship between the Triarhic Model of Psychopathy and violence in the romantic relationship of young people. The study included 226 students. The following questionnaires were used: The Triangular Measure of Psychopathy (Patrick et al., 2009), Questionnaire of Experiences of Violent Behavioral Behavior in Relationship (Ajduković et al., 2011) and Questionnaire of Expected Violent Behavioral Behavior in Relationship (Ajduković et al., 2011). Research has shown that girls are doing more violence, emotional and physical violence in relationships, while boys are doing more sexual violence. The results show that boys are more likely to experience total and emotional violence. Girls and boys are reported to experience physical and sexual violence at the same frequency. With the increase of overall psychopathic results, there is increase in the total violence committed in both sexes. For girls it has been shown that the higher score on the meanness, more emotional violence is committed. For boys it has been shown that the higher score on the meanness, more total, emotional, physical and sexual violence is committed. It has been shown that the higher disinhibition by boys suggests more emotional violence in relationships. The research has shown that there is no statistically significant correlation of the boldness with total violence and its components. By girls, with increase in overall psychopathy results, the results of total violence experienced and experienced emotional, physical and sexual violence are increasing. Boys with an increase in overall psychopathic results are experiencing increase of the total experienced and emotional violence. The research shows, the higher disinhibition by girls suggests more experienced total, emotional, physical and sexual violence. The higher score on the meanness by boys, they are experiencing more total, emotional and physical violence, and the higher disinhibition is, they are experiencing more emotional violence.
