Abstract
The past 2.5 decades have seen explosive growth in research and practice in the area of intimate partner violence (IPV), especially of perpetrators. In the present paper, the author reflects on his observations of key developments in the field and examines research that has increased our understanding of batterers, who they are, and how we might best work with them to end IPV. Issues and controversies that surround batterer treatment and research with batterers are also examined. The author calls for continued development of an empirical base to guide theory development and practice standards, as well as increased dissemination and translation of research into formats that are useful to clinicians.
