Violence in the affective-sexual relationships of adolescents is a theme that has been highlighted by the literature as a result of its high rates of prevalence. It has different characteristics, while many factors are shown to be associated with its occurrence. The present study investigated the affective-sexual relationships of adolescents, focusing on the experiences as perpetrators and victims of different types of violence between partners. We conducted a quantitative study with a descriptive, comparative and correlational design, with 124 heterosexual adolescents, aged 15 to 18 years (M = 15.94, SD = 0.65). As measurement instruments we used a sociodemographic questionnaire, the Family Background Questionnaire (FBQ), and the Conflict in Adolescent Dating Relationships Inventory (CADRI). The results showed percentages of violence that ranged from 14.7% for relational abuse committed to 97% for verbal/emotional violence suffered. We identified significant gender differences in the dimensions of threatening behavior (t = -3.172, p = 0.002) and physical violence (t = -3.037, p = 0.003) perpetrated by the participant, indicating that it is the girls who report that they practice this type of violence more often. No significant correlation was observed between experiences of violence in the family of origin and in the relationship with the partner (p > 0.05). However, there was an association between the occurrence of violence in the relationships of the adolescents and the presence of violence in the affective-sexual relationships of friends (p < 0.05). We highlight the importance of expanding the field of theory regarding this phenomenon, in order to assist with future interventions.
