Design outcomes

Primary

Measure	Time frame
The target parameters are - numeric SOAS-R score of the event - numerical subjective event severity The SOAS-R report form is completed when a staff member observes or experiences aggressive behavior by a patient. It consists of five categories, and each category includes multiple options to characterize the actual incident. The five categories capture 1) the provocation leading up to the aggressive incident, 2) the means used by the attacker during the incident, 3) the goal of the aggression, 4) the consequences for the victims, and 5) the immediate actions taken to stop or control aggressive behavior. An overall scoring system was developed to assess the overall severity of an aggressive incident. Each option in the columns is given a score, and the column score is determined by the option with the highest score. The overall severity score is derived by adding the five column scores together. The SOAS-R overall severity score ranges from 0 to 22 points, with scores of 0-7 indicating mild, 8-15 moderate, and 16-22 severe severity. In addition to the five columns, a Visual Analogue Scale (VAS) from 0 to 10 points is added to the SOAS-R form to assess the subjective severity of the incident.	—
