The Danger Assessment Instrument (DA), in its current form, is a 20-item actuarial test designed to assess the risk of serious or lethal intimate partner violence. It is intended for use with adult women who have suffered physical abuse at the hands of men who are their current or former intimate partners. Although originally developed to assist in safety planning conducted by people delivering services to victims, the DA more recently has been used by some law enforcement agencies to help manage the risks posed by perpetrators. Systematic review of the DA is complicated by the fact that it has been used in several different forms for a variety of different purposes and by the lack of a formal test manual.
