| Abstract: |
The Domestic Abuse, Stalking and Harassment and Honour-Based Violence (DASH) risk assessment is used by most UK police forces to assess risk in domestic abuse cases. This research assesses the efficacy of DASH in identifying offenders who commit deadly, potentially deadly, or persistent acts of domestic abuse. A random sample of 814 offenders were selected from domestic abuse incidents which occurred in the Dyfed-Powys Police area in Wales, UK, between January 2016 to December 2019. Responses to DASH from an offenders’ previous domestic abuse offence were analysed using Signal Detection Theory to calculate the Area Under the Curve. This determined if the level of risk based on the victims DASH responses could effectively predict the seriousness of a future domestic abuse incident. Each DASH item was examined by calculating the odds ratio to determine significant differences between the control group and the deadly offenders and the persistent offenders. The DASH performed well at predicting deadly offenders (AUC=0.67), and moderately well at predicting persistent offenders (AUC=0.60).The odds ratio analyses on the individual items of DASH identified 6 of the 27 questions had a large effect in differentiating between deadly offenders and control cases. 15 questions could identify persistent offenders compared to control cases. Although the DASH was found to be quite effective at predicting deadly and persistent offenders in operational police setting, there are more effective and efficient ways of determining risk levels of domestic abuse cases. The impact on the victim and time administering the DASH can be significantly reduced by asking only those questions found to have a significant effect on determining level of risk. |
