Abstract
Domestic violence refers to all incidents of violence and abuse between family members and those who are, or have been, in an intimate relationship. This includes physical, psychological, sexual, financial and emotional abuse. Domestic violence is estimated to cost the public purse in excess of £5 billion every year (Walby, 2004), not including the intangible, long-term, costs of trauma and emotional suffering for children, families and communities.
Project 360 is the first randomised-control trial of a multi-agency approach to dealing with repeat domestic violence in the UK.
Following current procedure, households assessed as high risk by responding police officers are provided with assistance from the Domestic Abuse Support Team (DAST). However, these households make up only four percent of the cases mentioned above. The remaining medium and low risk households do not receive DAST assistance unless seven or more incidents occur within the preceding 365 days. Project 360 extends the service currently offered through DAST by: 1) providing an intervention to households which do not qualify under current procedures; 2) reducing the response time of first contact with victims (currently seven days, on average, for DAST); 3) for households with children, expanding the intervention to pass information directly to schools.
The experimental design of Project 360 will allow us to estimate the causal effect of the intervention on a number of outcomes reflecting the impact on households, victims and children. Combining these outcomes with information on public expenditures we will provide a full cost-benefit analysis of the programme.

Experimental Details
Interventions
Intervention(s)
The intervention targets households that have experienced three incidents of police-reported domestic violence in 365 days. Households that meet these criteria are randomly allocated in either a treatment group or a control group. In the treatment group, victims will be contacted, by phone, by a trained outreach worker within 24hrs of the event. The engagement worker will offer to provide further assistance to the victim and, if assistance is accepted, visit the victim within 24 hours of the call. If children are in the household, schools will be informed that a domestic disturbance has taken place. Victims from households in the control group will receive the services available through current procedures.

Primary Outcomes
Primary Outcomes (end points)
The principal outcomes of interest will be: Number of police call-outs (made by the victim and made by a third party), participation with engagement workers, victim police statements (and withdrawal of statements), victim engagement in legal proceedings, and sentencing of perpetrators.
A second source of primary data will be a victim follow-up survey, conducted one month and four months following an incident. The survey will solicit self-reported measures from victims covering three areas: 1) Perceived safety/security/quality of life, 2) Awareness of and confidence in accessing support services, 3) Ongoing relationship with the perpetrator.
