Internationally there has been a call for a shift in mental health services towards a decrease in involuntary treatment and an increase in community-based care. So far, most research on reducing coercion has focused on services at the specialist health care level, and knowledge on how primary health care can facilitate and contribute to such a decrease is lacking. Through dialogue conferences and feedback meetings in five mid-sized municipalities in Norway, we have developed a comprehensive intervention for primary mental health care aimed at reducing involuntary admissions. Representatives from primary mental health care, specialist mental health care, GPs, police, persons with lived experience, and family carers participated in the co-creation of the intervention together with the research team. In this presentation, the process of developing the intervention will be presented.
