Alongside our operational monitoring, we work with several universities to formally evaluate some of our interventions to ensure they remain relevant and effective in tackling domestic abuse offending.
Existing evaluations of CARA have helped us to understand and measure the effectiveness of the CARA intervention, its impact on re-offending, and a cost-benefit analysis. Since the original evaluation led by Cambridge University, CARA has been evaluated internally by Hampshire Constabulary and more recently by the University of Birmingham. Currently, the University of Southampton is leading a multi-site evaluation in partnership with other universities. Nine police forces have signed up to be included in the evaluation.
