This qualitative study explores the opportunities and challenges of collaboration experienced by social workers and police officers when dealing with cases of intimate partner violence (IPV) and stalking. The study aims to examine their collaborative approaches in risk assessment and risk management by identifying the structures , supports, and foundations crucial for effective collaboration. Our data, collected from twelve interviews and one focus group interview with social workers and police officers, reveals that collaboration was facilitated by assigning specific roles to involved parties, proximity, structure and professionalism. These key factors emerged as crucial and contributing to the effectiveness of the collaborative efforts. Practitioners should consider integrating these key elements into their practices to enhance and improve collaboration when addressing cases of IPV and stalking. The study underscores the need for a well-defined framework and support structures to optimise the collaborative response to such complex and sensitive issues.
