The studies indicate that simulation method with real actors is an effective and appropriate education tool for these purposes. The main aim of the study is to describe the effect of the simulation training of psychiatry staff utilising simulation scenarios with actors and to evaluate the impact of the course on the confidence of psychiatry staff when dealing with violence. The participants (120 psychiatric nurses) answered the questionnaire (Confidence in coping with patient-initiated aggression was measured with the scale developed by Thackrey) at the beginning of the course, immediately after the course (paper questionnaire). The participants achieved the most significant progress in the areas of physical intervention during the contact with a violent patient and in their perceived self-confidence when facing a violent patient.
