Resumen: School violence towards peers and teen dating violence are two of the most relevant behaviour problems in adolescents. Although the relationship between the two types of violence is well established in the literature, few studies have focused on mediators that could explain this empirical relationship. We departed from the evidence that relates anger, emotional distress and impaired empathy to teen dating violence and juvenile sexual offending, to explore the role of personal distress, i.e., a self-focused, aversive affective reaction to another’s emotion associated with the desire to alleviate one’s own, but not the other’s distress; as a possible mechanism linking school violence towards peers and teen dating violence in a sample of Spanish adolescents. We also explored the prevalence of emotional and physical teen dating violence, both occasional and frequent, and the differences between boys and girls. A total of 1055 adolescents (49.2% boys and 50.8% girls) aged between 11 and 17 years (M = 14.06, SD = 1.34) who had had at least one romantic relationship within the last year, completed measures of school violence towards peers, teen dating violence, and personal distress. Statistical analyses revealed that occasional and frequent teen dating violence (both physical and emotional) was more frequent in girls than in boys, and that personal distress functioned as a partial mediator, with an overall model fit higher for boys than girls: in boys, partial mediation occurred for both physical and emotional teen dating violence; in girls, partial mediation occurred only for physical violence. The interpretation of the results is tentative given the novel nature of the study, and points to the evidence of the emotional costs of school violence and the importance of emotion and behavior regulation to undermine the social costs of personal distress.
