Disturbed behavior and patient aggression within psychiatric wards can threaten both patient and staff safety. To manage these patients, psychiatric wards often will use coercive measures such as solitary confinement. Patient aggression arises from a complex interaction between patient characteristics, staff characteristics, and the characteristics of the physical environment of the psychiatric ward itself. Most studies have focused on the dynamics between patient and staff characteristics; little research has been done to investigate how the physical environment of psychiatric wards might influence patient aggression and subsequently the use of coercive measures.
