“…Another recent treatment study, conducted by some of the same authors and using almost identical study design as Bratton et al (2013), provided evidence for Adlerian play therapy as another level 2 treatment for disruptive behavior (Meany-Walen, Bratton, & Kottman, 2014). While the remainder of play therapy interventions published since the year 2000 remain at level 4, there has been a growing number of 21st-century experimental and quasi-experimental research studies indicating positive treatment effects for several presenting problems, including internalizing problems (Packman & Bratton, 2003), ADHD (Ray, Schottelkorb, & Tsai, 2007), trauma (Schottelkorb, Doumas, & Garcia, 2012;Tyndall-Lind, Landreth, & Giordano, 2001;Shen, 2002), academic problems (Blanco & Ray, 2011), delayed language skills (Danger & Landreth, 2005), teacher-child relationship problems (Ray, 2007;Ray, Henson, Schottelkorb, Brown, & Muro, 2008), and adaptation to medical problems (Bloch & Toker, 2008;Jones & Landreth, 2002;Li & Lopez, 2007;Tsai et al, 2013). The empirical evidence for medical play therapy is particularly notable for its methodological strengths and promising results.…”
