It’s intriguing to look at self-control as a capacity to reduce aggression. In fact Galić and Ružojčić (2017) state that dispositional self-control, as measured with an according test, moderated negative behavior at work. Similarly, implicit self-control can be related to a reduction of anger and different types of aggression (Keatly, Allom, & Mullan, 2017).
Maybe like from the after-school anti-aggression sports program studied by Shachar, Ronen-Rosenbaum, Rosenbaum, Orkibi, and Hamama (2016), the impressive results including evidence for better self-control skills, reduced anger and less urge for physical aggression, could be replicated for adults. The program required the experiment group to sport five times a week, though. Would be interesting to know down to what intensity and frequency such a program would still yield similar benefits (Shachar et al., 2016).
