The aim of this review article is to present an overview of the, in the Nordic countries, relatively new research area ’children exposed to domestic violence’, and to discuss the implications of this research. The overview shows that the international research is primarily quantitative, focusing on children’s symptoms. Only a small part of the published research studies are qualitative. These studies use the term ‘experience’, rather than ‘exposed’, stressing the child’s subject status. The Nordic research is qualitative, and in line with early North-American studies, uses the term ‘to witness’. Although the field has greatly expanded, the field still have many unanswered questions concerning for example recilience, gender and ethnicity, and lack un understanding of the relational and contextual aspects from the child’s perspective.
