Can the 'Up2U' programme reduce violence by domestic abusers, and improve quality of life for victims?

INTERVENTION: Up2U: Creating Healthy Relationships is a modular group‐work therapy programme of six to nine months duration delivered in the community to voluntary referrals, supplementing usual support. Up2U was developed by Portsmouth City Council based on the principles of effective practice in offender rehabilitation, including the training and reinforcement of cognitive skills to moderate the associated underpinning dynamic risk factors for violence. The control arms will simply comprise usual community support with risk assessment and monitoring as for the intervention arm, and without assessment and monitoring. If usual support with assessment and monitoring is no different on the primary outcome measures to usual support alone then the two arms will be collapsed to produce a simple two armed trial. Usual support includes fragmented agency support for relevant needs, which may or may not be coordinated by a multi‐agency community panel (e.g., MARAC). CONDITION: Perpetration of violence and abuse against an intimate partner, with physical and mental health consequences for the victim/survivor. ; Mental and Behavioural Disorders PRIMARY OUTCOME: Violent re‐offending at 12 months as indexed by the frequency of official reports (arrests or cautions), or partner reports (police distress calls). SECONDARY OUTCOME: 1. Partner Quality of Life rated at 6 and 12 months using the SF‐12 and the EQ‐5D; 2. Risk of Re‐offending as assessed at 6 and 12 months using the LS/RNR INCLUSION CRITERIA: 1. To be eligible for referral a person must accept that they use abusive or unhealthy behaviours in their relationship and want to change these behaviours. 2. Referrals must be adult males or females in a relationship, including same sex
