title: [Aggressive behavior of mentally incompetent psychiatrically ill criminals during inpatient treatment].
abstract: OBJECTIVE, METHODS: To assess the amount of violent behaviour among mentally ill offenders NGRI during forensic long-term inpatient-treatment we retrospectively investigated the official incident-reports concerning verbal and physical aggression and damage to foreign property during an 8-year period in Austria's central high-security institution.
  
  
  RESULTS
  29.2% of our patients exhibited violent behaviour with only 7.8% being responsible for 41.1% of all incidents. Mentally impaired patients were significantly overrepresented in the violent group. Physical violence was reported in 25.8% (= 16.48 assaults/100 patients/year). 68% of the total amount of physical violence was directed against fellow patients. Violent behaviour was less driven by psychotic symptoms but rather by current everyday conflicts and stress situations.
  
  
  CONCLUSIONS
  The majority of incidents had only minor consequences. Yet, an inquiry concerning the offenders' intentions and the danger experienced by staff members indicated a reasonable violent potential also in minor assaults which appears to be important with respect to ward climate and distress of staff.
