Abstract

Inpatient aggression in psychiatric settings poses a serious management problem. This study reports the findings of a prospective pilot study on the Dynamic Appraisal of Situational Aggression – Inpatient Version (DASA-IV), a structured risk assessment tool for imminent aggression. The study was conducted in the State Hospital, the high secure psychiatric hospital for Scotland and Northern Ireland. The outcome data were aggressive incidents recorded on the Staff Observation Aggression Scale – Revised (SOAS-R) and incidents noted on the hospital's online recording tool. All measures were completed by nursing staff as part of their daily clinical routine to ensure ecological validity. The DASA-IV was found to be of moderate to good predictive power. Limitations and suggestions for further research are outlined, and the potential for implementation of the tool is discussed.
