Violent behaviour between inpatients and wardpersonnel is seen from a relational viewpoint. The reactions of the staff show a strong similarity with regressive transferences from the patients. Limit-setting as a method should be employed to contain the individuel behaviour of the patient as also so further the social climate on the ward. The method of limit-setting involves the reality testing of the patient, the transference reactions between patient and staff, clarity in decision-making and regulations, and architectural arrangements. These four levels of influence are separately discussed.
