Danger Assessment for Law Enforcement

The Danger Assessment for Law Enforcement (DA-LE) is an evidence-based risk assessment screening instrument, administered on scene by law enforcement officers, that identifies victims who are at the highest risk of severe/near-lethal assault.  It acts as a supplement to the police report. 


How it Works

An officer responding to a domestic violence call uses the DA-LE to collect a history of violence. The DA-LE consists of 11 questions.  A score that exceeds a pre-determined threshold indicates a victim at elevated risk of homicide and severe/near-lethal assault.  

The DA-LE is designed to be used in court to inform criminal justice proceedings including bail. The DA-LE can be used as a stand-alone tool or as part of a broader multidisciplinary team such as a Domestic Violence High Risk Team (DVHRT) that works together to prevent homicide. 

 The DA-LE is based on the Danger Assessment, an instrument developed by Dr. Jacquelyn Campbell, PhD, RN, FAAN to help abused women accurately assess the level of danger they are in from their partner or ex-partner. For more information, go to www.dangerassessment.org.

The Research Behind DA-LE

The DA-LE is a collaboration between the foremost researchers in the field of intimate partner homicide and Jeanne Geiger Crisis Center.

To develop the DA-LE instrument, Jeanne Geiger Crisis Center partnered with two leading researchers, Dr. Jacquelyn C. Campbell, PhD, RN, FAAN of Johns Hopkins University School of Nursing and Dr. Jill Theresa Messing, MSW, PhD of Arizona State University School of Social Work.
