If we want to support survivors of intimate partner violence (IPV) and their families and make them safer, perpetrators cannot be ignored. Evidence for what makes an IPV perpetrator programme most effective, is unclear. Furthermore, some populations, such as those who use substances, may require more tailoredapproaches.Two research programmes, funded by the UK’s National Institute of Health Research, are trialling new non-mandatory group-based interventions for male perpetrators who want to change their behaviour. The REPROVIDE intervention accepts self and agency referrals, including from children’s services and specialist domestic violence services. The ADVANCE integrated substance use and IPV intervention is delivered in substance use treatment services.The symposium will present an overview and initial findings from both programmes to address the following key questions:1. What are the main help-seeking routes and motivations for change for men who perpetrate IPV?2. What is the relationship between substance use and IPV?3. What interventions may be feasible and acceptable to address IPV in non-mandated populations?These questions will be answered by drawing on a mixed methods process evaluation including field notes, observations of group sessions, and interviews with male perpetrators from REPROVIDE; and findings from a meta-ethnography, systematic review and in-depth interviews with men in substance use treatment and their female current or ex-partners from ADVANCE. Preliminary findings from the acceptability and feasibility of delivering the REPROVIDE and ADVANCE perpetrator interventions will also be presented. The implications of these two interventions for the targeting and provision of support for abusive men willbe considered. Opening up the discussion to the audience will enable comparisons between the UK and Australian contexts and the sharing of good practice in the early identification of IPV as well as in the development of appropriate referral pathways and responses
