Violence in partnership is a very common social phenomenon that can be deduced from various studies that establish that violent behavior is highly represented already at a younger adolescent age. The research seeks to examine whether the level of self-esteem, misconceptions about a quality relationship, and justifying jealousy contribute to increasing the risk of committing violence in partnership. Previous research has mainly examined the prevalence of violence in partner relationships, but there is not a large number of studies on the correlation between beliefs about a quality relationship, the level of self-esteem and the justification of jealousy and commiting violence in partner relationships in the Republic of Croatia. Participants were collected by social media posts and the snowball method, with the survey conducted on a convenient non-probability sample of young people between the ages of 18 and 30. The results of this research show that there is a statistically significant positive correlation between the wrong beliefs of young people and the risk of committing violence. In other words, with the increase in the occurrence of wrong beliefs about a quality relationship, there is a more frequent occurrence of violent behavior in a partner relationship. A statistically significant positive correlation was found between the justification of jealousy in a partner relationship and the perpetration of violence between partners. The research identified a statistically significant negative correlation between self-esteem and committing violence in partnership. The hypotheses were tested in such a way that, in addition to the examination of the basic relationship of the variables through the Pearson coefficient (r) in the manner in which it was assumed, the model for predicting violence in a partner relationship was also examined, using the method of multiple regression analysis.
