This study investigated the effectiveness of an educational intervention designed to assist university staff in dealing with aggressive incidents. Participants in the study included 18 Admissions Office staff of a large Canadian research oriented university who had noted an increase in the number of aggressive incidents by rejected applicants. An ecological approach was utilized in designing the intervention, selecting a series of key features which comprised the content of the two-day workshop and based on which change was measured. Results of the study indicated that the intervention increased participants' sense of efficacy, their ability to identify a greater number of options to deal with aggressive incidents, and their sensitivity to the causes of aggression. The intervention also reduced participants' stress levels and created more efficient communication during violent incidents. (Contains 58 references.) (Author/JPB)
