Violence, in all its different manifestations, is a universal problem affecting individuals of different age groups, of different ethnic and religious backgrounds, and of different sexual orientations. Family violence and youth violence are interconnected. This special issue advances knowledge about child maltreatment, bullying, youth violence, dating violence, and intimate partner violence. This commentary critically discusses the contributions to the special issue in the context of the most recent research developments in family and youth violence. It concludes that long-term longitudinal studies with frequent assessments are needed to advance knowledge further, especially relating within-individual changes in influencing factors to within-individual changes in outcomes. It is highlighted that the intersection of family violence and youth violence remains a fertile field for further research, and that it is important to provide family, school and community services within an ecological focus.
