This quasi-experimental field trial examined the effectiveness of the Lethality Assessment Program (LAP), a police-social service collaboration wherein social service practitioners provide advocacy, safety planning, and referral for services over the telephone during police-involved intimate partner violence (IPV) incidents for women at high risk of homicide.


Although additional research is needed, the study concludes that the LAP is a promising evidence-informed intervention that holds the potential to increase survivors' safety and foster decisions of self-care. Structured telephone interviews were conducted with survivors as soon as possible after the incident of violence and again approximately 7 months later. The majority of participants (61.6 percent) recruited during the intervention phase of the study talked to the hotline advocates, and propensity score-matched analyses indicate that women who received the intervention reported using significantly more protective strategies and were victimized by significantly less physical violence than women in the comparison group.
