“…Thirteen of the papers reported on the treatment of one or two individuals (Braithwaite & Richdale, 2000;Davis et al, 2013;Falcomata, Roane, Muething, Stephenson, & Ing, 2012;Fisher, Lindauer, Alterson, & Thompson, 1998;Foxx & Garito, 2007;Foxx & Meindl, 2007;Hittner, 1994;Kern, Carberry, & Haidara, 1997;Kuhn, Hardesty, & Sweeney, 2009;Luiselli, Blew, Keane, Thibadeau, & Holzman, 2000;Matson, LoVullo, Boisjoli, & Gonzales, 2008;Robertson, Wehby, & King, 2013;Sigafoos & Meikle, 1996), and two studies involved 100 or more people Silverman et al, 2014). The higher number of participated studies involved drug treatments (Arnold et al, 2003;Hellings et al, 2005;King & Davanzo, 1996;Marcus et al, 2009;McDougle et al, 1996;McDougle, Kem, & Posey, 2002;McDougle et al, 1998;Owen et al, 2009;Silverman et al, 2014;Troost et al, 2005), while the low number studies were largely psychologically based interventions. Again, this makes sense in that drug interventions for aggression are far less time intensive than psychologically based treatments.…”
