The study involved 98 participants in dealing with internalizing behavior problems and externalizing behavior problems. Participants in the study were divided into experimental group and control group. The calculations show the great effect size (d = 0.59). It shows that the play therapy provides a great influence in reducing behavioral disorders in children. While play therapy provides a great influence in dealing with internalizing behavior problems (d = 0.60) and externalizing behavior problems (d = 0.58).
