This study compared rates of dating aggression among 16-year-old adolescents in Canada and Italy, as well as differential associations with dyadic risk factors. 664 Canadians (297 boys, 367 girls) and 578 Italians (315 boys, 263 girls) indicated the frequency of physical aggression towards a romantic partner. They also rated the level of conflict and power imbalance in their romantic relationship. The results revealed comparable rates of physical dating aggression in the two countries for both boys and girls. Dyadic risk factors were also significant, with levels of conflict associated with dating aggression in both countries, and power imbalance uniquely linked in Italy. Overall, the results point to dating aggression as a global problem among youth. (Contains 4 tables and 1 figure.)
