The article describes a secondary analysis of an intervention study, a practitioner research project, concerning the prevention of coercion among psychiatric staff members. The aim of the study was to explore how focus on patients’ experiences of coercion influences the staff members’ attempts to prevent such situations of coercion. The data in the secondary analysis were seven reports about the intervention study. The data were analyzed using comparative qualitative content analysis. Three types of staff characteristics, disclosing the philosophy, actions and perspectives of the staff on patients and critical situations which might arouse actions of coercion, were found: „the disease-oriented expert“, „the unnoticed ruler“ and „the dialogue-oriented expert“. The two first characteristics dominated among the staff before the intervention, and the last characteristic dominated after the intervention, revealing a change in attitudes and actions. The three characteristics are discussed in social constructionist and power perspectives, and suggestions for future implication in psychiatric practice put forward.
