Teen dating violence is becoming an increasingly common topic of research and expert discussions, which is not surprising given the high prevalence of this phenomenon and its serious consequences. It occurs during adolescence, a period that is inherently stressful and emotionally intense due to the numeorus changes it brings (Kuzman, 2009). Besides that, it is the period of first romantic relationships. Hodžić (2007) defines teen dating violence as patterns of violent behavior involving manipulation, threats, and coercion, used to control and intimidate a partner. The occurrence of teen dating violence is linked to underdeveloped social skills, with self-regulation being one of them. The connection between self-regulation and teen dating violence is the subject of a small number of studies, none of which have been conducted in Croatia. The aim of this thesis is to examine the relationship between self-regulation and teen dating violence. In order to achieve this, the paper focuses on determining the prevalence of teen dating violence and the level of self-regulation skills among high school students in Zagreb, examining whether there is a difference in the perception of self-regulation skills based on gender and is there a correlation between self-regulation and age, as well as determining the relationship between self-regulation skills and the perpetration and experience of teen dating violence. The data was collected as part of the research project "Research on Peer Violence among Children and Youth in the City of Zagreb." A representative sample of 400 students was selected for this study. The instruments used are: a Sociodemographic Characteristics Questionnaire, a Questionnaire on the Perpetration and Experience of Violence in Adolescent Relationships, and a Self-Regulation Questionnaire. According to the results, adolescents are most frequently exposed to control in an online environment, whether they are the ones controlling or experiencing it. Regarding self-regulation skills, participants rated themselves lowest in the dimension of behavioral regulation. An analysis of rank sums revealed a statistically significant difference between genders in emotional and behavioral regulation. Girls scored higher in the dimension of emotional (U=1500.50, z=-2.79, p>0.05) and behavioral regulation (U=1624, z=-2.208, p>0.05). Although no statistically significant correlation between self-regulation and age was found, a statistically significant correlation was established between teen dating violence and self-regulation. Regarding the perpetration of violence, a statistically significant positive correlation was found between emotional regulation and each form of teen dating violence, also between behavioral regulation and physical, emotional and sexual violence. In cases of experiencing teen dating violence, there was found a statistically significant positive correlation between emotional regulation and each form of relationship violence, as well as between behavioral regulation and each form of teen dating violence.
