AbstractPurpose: the aim of the article is to show the role of dating and dating violence victimisation, different socioeconomic characteristics, personal experiences of abuse, perceived social support, and the ability to resolve social problems in happiness among adolescents in Europe.Methods: the study had a cross-sectional design. The study participants were 1.528 students from secondary schools (age 13–16) in Spain, Italy, Romania, Portugal, Poland, and the UK. In order to understand which variables were associated with happiness, we fit multiple regression models.Results: the mean value of happiness is lower when teens are in a romantic or dating relationship and have suffered physical and/or sexual violence [β (CI 95%): -1.32(-2.41; -0.22)].Both not being a victim of bullying and cyberbullying [β(CI 95%):0.90 (0.38; 1.41)] and not witnessing domestic violence against the mother β(CI 95%):1.97(1.06; 2.87)] is associated with relatively higher mean happiness value compared to having such experiences of violence. Also, problem-solving skills [β (CI 95%):0.13 (0.11; 0.14)] and perception of social support [β (CI 95%): 0.03 (0.02, 0.03)] is positively associated with mean value of happiness.Conclusions: there is an association between dating violence victimisation, and happiness among adolescents in Europe. The results suggest the importance of creating healthy, non-violent romantic relationships to build happiness during adolescence, the importance of seeking social support and to provide educational interventions focused on the development of problem-solving skills.
