“…Systematic reviews on bullying interventions showed that to date few programs existed that target cyberbullying (Cantone et al, 2015;Mishna, Cook, Saini, Wu, & MacFadden, 2011;Van Cleemput et al, 2013), and that effects were often limited to increasing Internet safety knowledge (Mishna et al, 2011). Since these reviews, however, several new intervention and prevention studies against cyberbullying among adolescents have been published (Chaux, Velasquez, Schultze-Krumbholz, & Scheithauer, 2016;Cross et al, 2016;Del Rey, Casas, & Ortega, 2016;Gradinger, Yanagida, Strohmeier, & Spiel, 2016;Palladino, Nocentini, & Menesini, 2016;Schultze-Krumbholz, Schultze, Zagorscak, W€ olfer, & Scheithauer, 2016). All these studies showed significant reductions in cyberbullying involvement despite variations in design and focus.…”
