Goal of this study was to test if there are gender differences in sexual and emotional jealousy and various forms of violence in a relationship, and to determine the contribution of the two types of jealousy to various forms of violence in the relationship. The study included 175 participants. A measure of jealousy is applied defined by method of forced choice and Likert-scale jealousy measures, questionnaire committed partner violence (UPPN) and questionnaire experienced partner violence (UDPN). The results do not support the evolutionary view when both measures of jealousy are used. In fact when the method of forced choice is used the men are more sexually and women are more emotionally jealous while the Likert scale of jealousy implies that women are both sexually and emotionally more jealous. As for gender differences in commiting and experiencing violence in a relationship, it was discovered that girls commit more psychological and physical violence, as well as young men experience psychological and sexual violence. For young men, it was discovered that they commit more sexual violence than girls, experience more physical violence and as well as girls experience psychological and sexual violence. A third hypothesis was not confirmed since for certain types of committed and experienced violence neither type of jealousy proved as a significant predictor.
