Up2U: designing and validating a new evidence-based programme for perpetrators of domestic abuse who want to change.

Introduction: Domestic abuse is a pervasive issue rooted in patterns of power and control, contributing to a significant number of high-harm offenses both in the United Kingdom and internationally. While programmes have been aiming to disrupt abusive cycles through the understanding and recognition of harm, there is widespread disagreement on what effective interventions should look like. This study addresses this gap. Methods: A mixed-methods, multi-phase approach was adopted to evaluate the Up2U programme in Dorset, identify current challenges, and offer recommendations for future design based on evidence and best practice. A literature review, a workshop with key stakeholders, interviews, questionnaires, and a focus group with programme providers were conducted. Results: Crucial needs were identified, including the implementation of tailored interventions, hiring skilled facilitators, supporting victims, promoting perpetrator accountability, refining the programme structure, investing in multi-agency collaborations, evaluation, and engagement/retention. Conclusion: Recommendations were drafted aligned with Home Office standards for domestic abuse perpetrator intervention. Designing flexible, evidence-based programmes that center on victim safety while holding perpetrators accountable was a crucial element of the study. Well-trained, supported facilitators and accessible, engaging content are essential for meaningful participation. Ongoing monitoring and impact evaluation to track behavioral changes are proposed.
