“…Moreover, aggressive incidents occurring in a psychiatric ward are shown to be associated with a decreased well-being of working staff, diminished professional behavior, an increased number of absences, and a higher workload (Di Martino, 2002;Estryn-Behar et al, 2008;Nijman, Palmstierna, Almvik, & Stolker, 2005;van der Helm, Boekee, Stams, & van der Laan, 2011). Furthermore, evidence exists for an association between inpatient aggression and a higher number of offenses after treatment (Cochran, Mears, Bales, & Stewart, 2014). The fact that inpatient aggression has such a severe negative impact on both staff and patients and shows possible negative consequences for society makes effective management and prevention of aggression key priorities in mental health settings (Kaltiala-Heino et al, 2007;Masters & Bellonci, 2002;Tremmery et al, 2012).…”
