The SOAS-R is an easy-to-use instrument that helps documenting a wide range of aggressive behaviours.

SOAS-R, stands for The Staff Observation Aggression Scale – Revised. With this instrument caregivers can quickly document what exactly happened during aggressive occurrences as the answer options in the instrument’s five columns only have to be marked by the ward staff. It gives a better insight of when and why patients and clients are most likely to engage in aggressive behaviour, to intervene effectively and to prevent an increase of aggression. 

Request more about SOAS-R

The SOAS‐R is a tool for monitoring a wide range of (self‐) destructive acts, which allows for better policies that will result in less aggression.

Proper assessment of aggressive behavior is essential for an understanding of its causes. The most important reason all agressive incidents should be reported is to allow arrangements for prompt measures. Oftentimes aggressive incidents result from minor aggressive incidents that cannot be prevented if care is untimely, therefore reporting incidents when they occur is so important. Another equally important reason to report all agressive incidents is that they must be investigated and their causes found, to prevent the same from happening again to someone else. The SOAS-R is an instrument for monitoring the frequency, nature, and severity of aggressive incidents. The use of the SOAS-R will help get better insight in why and when aggression occurs after which policies can be adjusted in order to reduce violence.
