Research Context

Summary of Analytic Methods:
An exploratory analysis of tracking data of both crime and policing developments in each case that can inform the development of a targeting and testing strategy to reduce harm from domestic abuse known to police or courts.

Describing pathways of victims and offenders with varying times at risk, with some analyses using standard follow-up periods such as 1, 3, 6,9 and 12 months or 1 year, depending on the shape of the pathway groups.
Some analyses will also compare differences between pathways, such as offenders who are vs. are not subjected to Domestic Violence Prevention Orders (DVPOs) after receiving a Domestic Violence Prevention Notice (DVPN), or victims who seek domestic abuse Non-molestation Orders (NMOs) versus victims who do not seek NMOs but are the subjects of restraint on their offenders by DVPNs or DVPOS. This exploratory analysis will also include a back-end ranking of Cambridge Crime Harm Index (CHI) scores for victims, offenders and dyads, with certain standard time frame (e.g., one year), in relation to the power few concentrations and the implications of those concentrations for potential targeting strategies.

The CHI score will be calculated both before AND after the restraining order was issued/granted, with equal exposure times. Also, the gap between known breaches and subsequent enforcement will be explored by comparing descriptive characteristics of action vs. no action at each stage. Finally, a descriptive breakdown of costs of various pathways will conclude the analyses.

These results can identify evidenced based practice, leading directly to a targeting strategy approved by Chief officers and implemented by Inspectors, Sgts., Constables and others dealing domestic abuse in Merseyside and around the country.

Research Methodology

​Any and all DVPOs, DVPNs or NMOs issued by Merseyside Police or Merseyside courts from 29 May 2014 through 3 February 2017, currently counted at 1,479 cases.

This research will undertake an exploratory analysis of tracking data of both crime and policing developments in each case that can inform the development of a targeting and testing strategy to reduce harm from domestic abuse known to police or courts: demographics of victims, their offenders and their dyad (age, gender, sexual orientation, prior domestic abuse, etc); whether cases have had prior contact with police; the pathways for subsequent official actions, and reported harm by domestic abuse against victims or offenders. Including breach of orders, arrest, prosecution, incarceration or other sanctions, and all crimes in which either victim or offender are the new instant victim or offender in domestic abuse
