Coercion in challenging situations is often seen as a necessary component of psychiatric care. This study aims to describe staff members' reasoning about their choice of action in challenging situations in inpatient psychiatric care. Focus group interviews with 26 staff members were analyzed using qualitative content analysis. The results provide an overview of the integrated structure of participants' reasoning and suggest that staff members' reasoning about choice of action can be described as a matter of either solving the staff's problems or meeting the patients' needs. These results can be of use in further research, educational interventions, and staff development activities.
