Background: Studies have shown that people with mental health issues such as psychosis to a greater extent is affected by violence exposure and that healthcare does not identify this issue to a great extent. Aim: The aim of the study was to examine if a web-based course could affect health care staff’s approach and use of procedure in working with violence exposure for their patients. Methods: The selected study groups were health staff working with in- and outpatient care in a psychosis care facility. It was based on a convenience selection sample. The design of the study was a quantitative interventions research with before and after measurement using an Internetbased questionnaire. Results: The result showed that there’s a lack of use in standardized methods and the participants of the study expressed a desire for a routine-based procedure when working with violence vulnerability and exposure. Moreover, education, coaching and guidelines were more frequently requested after the web-based course, but the participants especially requested more local guiding principles in their workplace. Conclusion: The authors can see a clear need for additional studies with the purpose of bringing forth evidence-based methods for how health staff can ask about violence exposure and subsequently, what should or can be done if such information is gathered. The future prospect is thus that more scientific evidence will be able to form clearer and more favourable guidelines in different types of healthcare facilities to accomplish this endeavor.
